This is a culmination of the efforts of many personnel over the 49 00:03:43,640 --> 00:03:46,300 years to get to this milestone of an accomplishment. 50 00:03:49,380 --> 00:03:52,120 And at an experimental research base in Florida. 51 00:03:57,900 --> 00:04:02,480 Senior Chief Josh Pearsall and his crew are preparing to evaluate one of the 52 00:04:02,480 --> 00:04:05,480 first completed FSEs ever delivered to the Navy. 53 00:04:08,940 --> 00:04:13,240 Today's mission is operational test of the thrust system over water. 54 00:04:13,680 --> 00:04:17,240 We're going to be operating at high weight and power. 55 00:04:21,360 --> 00:04:24,860 Engineers have created a craft like no other on the ocean. 56 00:04:27,310 --> 00:04:29,590 The ship -to -shore connector is the U .S. 57 00:04:29,850 --> 00:04:32,130 Navy's latest and greatest amphibious vehicle. 58 00:04:35,470 --> 00:04:40,550 Built to conquer the planet's coastlines, this versatile vehicle can 59 00:04:40,550 --> 00:04:44,550 the sea and land to deliver troops and cargo to remote locations. 60 00:04:48,670 --> 00:04:53,350 Powered by four gas turbine engines that produce an excess of 24 ,000 61 00:04:53,350 --> 00:04:54,350 horsepower, 62 00:04:56,140 --> 00:05:01,400 The ship -to -shore connector can reach speeds of 35 knots in waves up to 4 feet 63 00:05:01,400 --> 00:05:08,040 high and transport a payload of either 145 combat 64 00:05:08,040 --> 00:05:14,980 Marines or 74 tons of equipment, enough to carry the Abrams M1A1 65 00:05:14,980 --> 00:05:17,280 tank fitted with a full -width mine plow. 66 00:05:22,560 --> 00:05:26,760 Once the finished vehicle enters active service, it must be able to access 67 00:05:26,760 --> 00:05:30,160 environments that would be impossible to reach with other landing craft. 68 00:05:32,740 --> 00:05:36,580 The uniqueness of the platforms that the Navy and Marine Corps team are working 69 00:05:36,580 --> 00:05:41,240 with industry to design have to be able to be better than just a normal craft or 70 00:05:41,240 --> 00:05:42,219 a normal boat. 71 00:05:42,220 --> 00:05:46,580 So we talk about a deployed scenario and the lack of infrastructure in a foreign 72 00:05:46,580 --> 00:05:51,100 location. We absolutely have to provide solutions that allow us to execute these 73 00:05:51,100 --> 00:05:53,020 missions across a myriad of scenarios. 74 00:05:54,440 --> 00:05:58,280 For inspiration, engineers must look to the innovators of the past. 75 00:06:07,580 --> 00:06:13,960 On the British coast, physicist Andrew Steele has traveled to discover the 76 00:06:13,960 --> 00:06:16,520 secrets of a historic military innovation. 77 00:06:19,470 --> 00:06:23,430 To you and me, this just looks like a cold day at the beach. But to engineers 78 00:06:23,430 --> 00:06:25,210 the military, this represents a challenge. 79 00:06:25,630 --> 00:06:29,990 How can you move seamlessly between land and water and back again without having 80 00:06:29,990 --> 00:06:33,470 to spend ages loading and unloading boats? And if you're in the military, 81 00:06:34,170 --> 00:06:35,330 basically being a sitting duck. 82 00:06:37,890 --> 00:06:41,810 It's a problem English engineer Sir Christopher Cockrell spent years 83 00:06:41,810 --> 00:06:42,810 contemplating. 84 00:06:44,790 --> 00:06:45,790 His solution. 85 00:06:46,040 --> 00:06:50,360 A whole new type of vehicle eliminating the boundary between sea and land. 86 00:06:51,520 --> 00:06:52,980 The hovercraft. 87 00:06:59,680 --> 00:07:06,640 This amazing machine is the SRN5, the Saunders Row Nautical 5 hovercraft. And 88 00:07:06,640 --> 00:07:10,960 it's the world's first production hovercraft based on the pioneering work 89 00:07:10,960 --> 00:07:11,960 Christopher Cockrell. 90 00:07:12,360 --> 00:07:13,820 And isn't it beautiful? 91 00:07:14,100 --> 00:07:17,120 It looks sort of retro and yet futuristic at the same time. 92 00:07:18,680 --> 00:07:25,040 After making its debut flight in 1964, the SRN -5 was the first hovercraft to 93 00:07:25,040 --> 00:07:26,200 enter military service. 94 00:07:29,220 --> 00:07:31,720 This craft was a real trailblazer. 95 00:07:32,060 --> 00:07:35,760 It still got essentially all the same technology as powers a modern 96 00:07:35,940 --> 00:07:39,680 And this was the first commercially successful hovercraft in the world. 97 00:07:41,930 --> 00:07:46,650 The SRN -5 was the result of more than five years of research and development. 98 00:07:48,270 --> 00:07:51,150 Capable of floating across both land and water, 99 00:07:52,290 --> 00:07:56,190 Cockrell's game -changing technology would go on to transform the nature of 100 00:07:56,190 --> 00:07:57,470 amphibious operations. 101 00:08:00,390 --> 00:08:04,530 Given that this vehicle can do something that sounds miraculous, hover in midair 102 00:08:04,530 --> 00:08:08,770 and move over almost any kind of terrain, it's really based on some 103 00:08:08,770 --> 00:08:09,770 simple physics. 104 00:08:10,310 --> 00:08:14,990 One of the big innovations in the SRN5 was that enormous Rolls -Royce engine at 105 00:08:14,990 --> 00:08:18,450 the top there, which is powering the whole hovercraft. And what does it 106 00:08:18,670 --> 00:08:21,370 Well, the first crucial thing is this fan in here. 107 00:08:21,590 --> 00:08:23,650 It doesn't look like a fan that you might normally see. 108 00:08:23,850 --> 00:08:24,950 Its blades are vertical. 109 00:08:25,190 --> 00:08:29,390 It's something called a centrifugal fan. And this fan acts as the lift fan. It's 110 00:08:29,390 --> 00:08:32,710 the crucial thing that makes this a hovercraft. It sucks air from the 111 00:08:32,710 --> 00:08:36,950 and uses it to fill up this enormous skirt underneath the vehicle and lift it 112 00:08:36,950 --> 00:08:39,090 all up off the ground, reducing that friction. 113 00:08:42,789 --> 00:08:47,690 To make the hover work, air from the fan is channeled into a thin curtain around 114 00:08:47,690 --> 00:08:53,330 the perimeter of the vehicle, lifting it off the ground and trapping a cushion 115 00:08:53,330 --> 00:08:54,830 of air under the hovercraft. 116 00:08:57,810 --> 00:09:01,670 The second critical part of this vehicle is that there, the thrust fan, an 117 00:09:01,670 --> 00:09:05,370 enormous set of rotor blades. And what that does is it sucks air and pushes it 118 00:09:05,370 --> 00:09:07,210 backwards, thrusting the hovercraft forward. 119 00:09:08,130 --> 00:09:13,190 Another critical innovation on the SRN5 is this thing, the hovercraft skirt. 120 00:09:13,490 --> 00:09:16,170 It traps the air, meaning less of it can escape. 121 00:09:16,370 --> 00:09:19,670 And because it's made of this flexible, rubbery material, it can adopt the 122 00:09:19,670 --> 00:09:23,270 contours of whatever terrain it's moving over, giving it incredible flexibility. 123 00:09:25,450 --> 00:09:29,210 Cockrell's design revolutionized ship -to -shore operations forever. 124 00:09:31,210 --> 00:09:36,070 This beauty is basically a modern version of the SRN -5, and it operates 125 00:09:36,070 --> 00:09:37,450 exactly the same principles. 126 00:09:38,470 --> 00:09:40,870 So how do those principles work in practice? 127 00:09:42,070 --> 00:09:44,510 They're just driving straight towards the sea. 128 00:09:44,730 --> 00:09:51,550 And how have engineers modernized the design for the most 129 00:09:51,550 --> 00:09:54,290 advanced ship -to -shore vehicle in naval history? 130 00:09:55,110 --> 00:09:58,350 We can make a landing almost anywhere on the planet with this technology. 131 00:10:01,450 --> 00:10:06,050 Engineer Christopher Cockrell developed the concept behind the SRN -5 in the 132 00:10:06,050 --> 00:10:07,050 1950s. 133 00:10:08,250 --> 00:10:13,190 Its fan and skirt design allowed the hovercraft to do what no other vehicles 134 00:10:13,190 --> 00:10:14,190 the time could. 135 00:10:16,730 --> 00:10:21,510 By flying on its air cushion, the craft can transition between land and sea 136 00:10:21,510 --> 00:10:25,830 without stopping, a game -changing innovation that revolutionized landing 137 00:10:25,830 --> 00:10:26,830 operations. 138 00:10:29,010 --> 00:10:33,590 Physicist Andrew Steele is about to experience this remarkable capability 139 00:10:33,590 --> 00:10:34,590 hand. 140 00:10:35,550 --> 00:10:40,010 So, let's get those fans going and fire this baby up. 141 00:10:54,730 --> 00:10:58,530 We're just driving straight towards the sea, which is completely crazy. 142 00:11:00,770 --> 00:11:01,930 That is bizarre. 143 00:11:02,370 --> 00:11:05,270 Just driving smoothly from the beach straight into the sea. 144 00:11:06,630 --> 00:11:08,590 It's a chilly morning out here. 145 00:11:12,350 --> 00:11:15,730 Now the holograph's up and running, we've got that miffed fan blowing the 146 00:11:15,730 --> 00:11:18,410 into the cushion underneath us. We're just hovering out here. 147 00:11:21,470 --> 00:11:26,440 More than 60 years after its introduction, the hovercraft has helped 148 00:11:26,440 --> 00:11:28,800 how the military moves from ship to shore. 149 00:11:30,820 --> 00:11:33,800 You can really see why the hovercraft is such a breakthrough. 150 00:11:34,260 --> 00:11:38,120 It's such a simple idea, but it's such a powerful, versatile vehicle. 151 00:11:38,520 --> 00:11:39,900 One of the most versatile on the planet. 152 00:11:41,700 --> 00:11:43,180 All right, Ben, take us home. 153 00:11:58,860 --> 00:12:03,660 By supersizing the air cushion innovation pioneered by Cockrell, 154 00:12:03,660 --> 00:12:07,020 made the SSC the most capable hovercraft on Earth. 155 00:12:09,580 --> 00:12:13,320 We can reach up to 70 % of the world's coastline on the hovercraft. 156 00:12:13,780 --> 00:12:16,980 We can make a landing almost anywhere on the planet with this technology. 157 00:12:19,060 --> 00:12:23,740 Today, pilot Josh Pearsall and his team in Florida are preparing to put the 158 00:12:23,740 --> 00:12:25,440 advanced air cushion to the test. 159 00:12:25,690 --> 00:12:28,610 on one of this amazing vehicle's first flights. 160 00:12:35,010 --> 00:12:41,990 By flying six 161 00:12:41,990 --> 00:12:47,290 feet above the surface, the SSC can overcome obstacles that would make 162 00:12:47,290 --> 00:12:49,470 impossible for traditional landing craft. 163 00:12:52,910 --> 00:12:58,620 It allows us to go Almost anywhere over water and land itself, whether it's 164 00:12:58,620 --> 00:13:02,420 sand, dirt, ice, you name it, it can go there. 165 00:13:08,840 --> 00:13:10,020 In Louisiana, 166 00:13:11,180 --> 00:13:15,860 engineer Ryan Schaffernacher has access to the impressive inner workings of the 167 00:13:15,860 --> 00:13:17,060 oversized air cushion. 168 00:13:18,460 --> 00:13:21,520 So I'm standing inside the bag of the SSC. 169 00:13:22,080 --> 00:13:25,380 Directly above me is where we install the lift fan volute. 170 00:13:25,820 --> 00:13:29,580 Inside that volute is the lift fan impeller. The impeller drives air 171 00:13:29,580 --> 00:13:34,020 this duct inside the bag and also drives air upwards through the bow thruster. 172 00:13:35,760 --> 00:13:40,880 And in order to enhance Cockrell's early design, the SSC's engineers have 173 00:13:40,880 --> 00:13:43,380 devised an updated take on the skirt system. 174 00:13:45,240 --> 00:13:48,400 So here we're installing the advanced skirt for the SSC. 175 00:13:48,780 --> 00:13:52,880 It is a vulcanized rubber over Kevlar fiber reinforcement. 176 00:13:54,460 --> 00:13:57,100 The air cushion works via the lift band. 177 00:13:57,440 --> 00:14:01,940 So through our main engines, we transform that power through the lift 178 00:14:01,940 --> 00:14:03,520 drive air pressure into the skirt. 179 00:14:03,760 --> 00:14:06,260 The skirt is a bag and finger type system. 180 00:14:06,600 --> 00:14:10,860 The fingers direct that air pressure to the exterior of the craft, providing 181 00:14:10,860 --> 00:14:11,860 it's lift. 182 00:14:14,680 --> 00:14:17,060 By powering two giant fans. 183 00:14:17,840 --> 00:14:21,340 The enormous skirt is filled with air in a matter of seconds. 184 00:14:22,820 --> 00:14:26,740 Hundreds of individual fingers wrap around the perimeter to create a curtain 185 00:14:26,740 --> 00:14:29,000 air that lifts the SSC off the ground. 186 00:14:31,080 --> 00:14:36,200 Each finger can move independently, allowing them to flex when traveling 187 00:14:36,200 --> 00:14:39,140 uneven surfaces to improve ride quality and handling. 188 00:14:40,780 --> 00:14:44,920 And the small cross -section of each finger helps reduce friction to enable 189 00:14:44,920 --> 00:14:46,020 increased speeds. 190 00:14:48,270 --> 00:14:52,010 The skirt is the key for the craft. It's what makes this an air -cushion 191 00:14:52,010 --> 00:14:54,550 vehicle, right? It's what makes it fully amphibious. 192 00:14:55,070 --> 00:14:57,950 Without this technology, it wouldn't be able to perform mission. 193 00:15:01,690 --> 00:15:06,670 But the SSC requires more than just its advanced skirt to operate effectively. 194 00:15:07,830 --> 00:15:13,110 A key factor in enabling us to be able to transport people and cargo to the 195 00:15:13,110 --> 00:15:14,370 beach is speed. 196 00:15:15,350 --> 00:15:17,450 We're in a contested environment oftentimes. 197 00:15:18,090 --> 00:15:22,550 We're against an adversary, and we need to be able to quickly maneuver so that 198 00:15:22,550 --> 00:15:25,810 we can support and execute our mission in a timely and efficient manner. 199 00:15:27,830 --> 00:15:31,530 And the key to achieving this objective is plenty of power. 200 00:15:34,650 --> 00:15:40,370 What we have before us here is the Rolls -Royce MT -7 gas turbine engine. There 201 00:15:40,370 --> 00:15:43,910 are four of these on the SSC platform, which provide propulsion. 202 00:15:45,480 --> 00:15:49,940 These impressive engines drive a pair of thrust propellers that measure in at 203 00:15:49,940 --> 00:15:54,320 almost 12 feet across and push the FSC forward at high speed. 204 00:15:55,280 --> 00:15:58,240 So let's look at the performance overall for the craft. 205 00:15:58,460 --> 00:16:01,560 We're looking at a top speed somewhere between 30 to 40 knots. 206 00:16:01,800 --> 00:16:06,680 This engine was selected because of its lightweight and its pound -for -pound 207 00:16:06,680 --> 00:16:08,120 punch in the way of power. 208 00:16:14,000 --> 00:16:16,440 At the experimental test base in Florida, 209 00:16:17,620 --> 00:16:23,320 Senior Chief Josh Pearsall is one of the few people to have experienced the 210 00:16:23,320 --> 00:16:25,220 speed of the SSC firsthand. 211 00:16:26,540 --> 00:16:29,120 I am very impressed by what I've seen of it so far. 212 00:16:29,640 --> 00:16:34,280 The advantages of being able to move fast that allows us to rapidly deploy 213 00:16:34,280 --> 00:16:38,380 forces around the world and build up the force that we need in any terrain. 214 00:16:40,680 --> 00:16:45,500 As part of today's test flight, Josh gets to put these powerful engines 215 00:16:45,500 --> 00:16:46,500 their paces. 216 00:16:46,920 --> 00:16:48,100 All right, here we go. 217 00:16:48,440 --> 00:16:49,840 Start in one and two, Bravo. 218 00:16:50,400 --> 00:16:51,420 Start in one and two, Bravo. 219 00:16:56,640 --> 00:17:02,840 Combined, the SSC's engines produce around 40 ,000 pounds of thrust, the 220 00:17:02,840 --> 00:17:04,780 equivalent of an F -35 jet. 221 00:17:05,960 --> 00:17:07,440 Got rotation all around. 222 00:17:07,920 --> 00:17:08,920 Roger. 223 00:17:13,710 --> 00:17:18,910 And with such mighty mechanical muscle at its disposal, this all -new 224 00:17:18,910 --> 00:17:22,849 powerhouse will be able to accomplish its mission at previously impossible 225 00:17:22,849 --> 00:17:23,849 speeds. 226 00:17:29,190 --> 00:17:32,130 It's a critical element of the SSD's design. 227 00:17:33,010 --> 00:17:37,330 But the demands of the military's mission pose more challenges for 228 00:17:38,110 --> 00:17:42,750 You have to make design selections that are both lightweight to allow the craft 229 00:17:42,750 --> 00:17:43,559 to fly. 230 00:17:43,560 --> 00:17:47,800 but also rigid enough to perform a very heavy payload transition from the ship 231 00:17:47,800 --> 00:17:48,800 to the shore. 232 00:17:49,440 --> 00:17:53,680 To find a solution, they must turn to the great innovators of the past. 233 00:17:54,340 --> 00:17:59,000 You can imagine soldiers getting ready to fly this plane into battle. 234 00:18:04,660 --> 00:18:08,360 To move some of the U .S. military's most heavy -duty equipment. 235 00:18:10,320 --> 00:18:16,360 In some of the planet's hardest -to -reach locations, engineers have created 236 00:18:16,360 --> 00:18:18,420 awe -inspiring amphibious vehicle. 237 00:18:23,660 --> 00:18:25,560 The ship -to -shore connector. 238 00:18:29,980 --> 00:18:36,820 Designed to be deployed from transport ships known as sea bases, the SSC can 239 00:18:36,820 --> 00:18:39,100 fly at high speeds across the open ocean. 240 00:18:41,640 --> 00:18:46,360 and deliver a payload weighing the equivalent of 11 African elephants to 241 00:18:46,360 --> 00:18:47,360 any terrain. 242 00:18:52,720 --> 00:18:57,840 But the need to launch its operations from far offshore can create challenges 243 00:18:57,840 --> 00:19:02,080 that the Navy's engineers and the manufacturing team in Louisiana need to 244 00:19:02,080 --> 00:19:03,080 overcome. 245 00:19:04,160 --> 00:19:09,410 We're typically looking at going from ship... that are over the horizons 246 00:19:09,410 --> 00:19:11,530 anywhere between 10 to 20 miles. 247 00:19:11,810 --> 00:19:17,510 And then allowing cargo and Marines and personnel to get from the ship to the 248 00:19:17,510 --> 00:19:18,510 shore. 249 00:19:18,770 --> 00:19:23,750 Typically, this can be in a contested environment, so we have to be agile. 250 00:19:28,950 --> 00:19:35,050 All hovercraft of this type must be able to launch from mothership, transition 251 00:19:35,050 --> 00:19:39,270 across the water, and navigate a range of obstacles on the way to shore, 252 00:19:39,550 --> 00:19:41,670 potentially including hostile fire. 253 00:19:43,150 --> 00:19:45,330 There's absolutely no room for compromise. 254 00:19:45,570 --> 00:19:48,990 Agility is a core feature of design for this platform. 255 00:19:50,870 --> 00:19:56,190 To maximize maneuverability, engineers have equipped the SSC with a trio of 256 00:19:56,190 --> 00:19:57,190 steering solutions. 257 00:19:58,110 --> 00:20:04,010 The SSC platform is designed with three primary effectors for maneuverability. 258 00:20:04,400 --> 00:20:08,280 Those components are the controllable pitch propeller, the rudders, and the 259 00:20:08,280 --> 00:20:09,280 thruster. 260 00:20:09,720 --> 00:20:13,660 What you see before you are six controllable pitch propeller blades. 261 00:20:13,960 --> 00:20:18,580 The two rudders you see on the port and the starboard side provide maximum 262 00:20:18,580 --> 00:20:20,440 steering capability for the platform. 263 00:20:21,260 --> 00:20:26,060 80 % of the craft's maneuverability factors are controlled right here with 264 00:20:26,060 --> 00:20:28,100 rudders and the controllable pitch propeller blades. 265 00:20:31,470 --> 00:20:35,550 By adjusting the pitch of the propeller blades, the amount of thrust generated 266 00:20:35,550 --> 00:20:36,550 can be varied. 267 00:20:38,270 --> 00:20:41,910 When the blade angle is increased, more thrust is produced. 268 00:20:42,710 --> 00:20:46,130 And when the blade angle is decreased, thrust is reduced. 269 00:20:47,890 --> 00:20:52,090 The rudders then interrupt the airflow coming from the propellers pushing the 270 00:20:52,090 --> 00:20:54,030 stern of the craft in the desired direction. 271 00:20:58,990 --> 00:21:03,270 The bow thrusters provide that fine -tuning aspect of maneuverability. 272 00:21:05,070 --> 00:21:09,490 By directing a stream of pressurized air from the SSC's lift fan through 273 00:21:09,490 --> 00:21:14,990 rotatable nozzles, the bow thrusters move the craft in the opposing 274 00:21:19,170 --> 00:21:20,650 Off the coast of Florida. 275 00:21:21,350 --> 00:21:22,990 Just enough to get through the bridge. 276 00:21:25,260 --> 00:21:29,280 Senior Chief Josh Pearsall is testing out the SSC's agility. 277 00:21:35,100 --> 00:21:40,020 Under his direction, the pitch propellers, rudders, and bow thrusters 278 00:21:40,020 --> 00:21:42,260 tandem to precisely maneuver the craft. 279 00:21:43,380 --> 00:21:44,760 All right, here we go. 280 00:21:44,980 --> 00:21:45,980 Roger. 281 00:21:48,100 --> 00:21:53,220 Capable of seamless transitions between forward, reverse, and lateral movement. 282 00:21:53,580 --> 00:22:00,120 The SSC can even turn 360 degrees inside its own footprint, allowing it to 283 00:22:00,120 --> 00:22:02,460 navigate through congested terrain with ease. 284 00:22:04,720 --> 00:22:09,300 But agility alone is not nearly enough for the SSC to meet its mission. 285 00:22:14,020 --> 00:22:19,610 A key consideration in the design process for SSC... There's weight and 286 00:22:19,610 --> 00:22:24,050 savings. We have to ensure that there's a balance between what each component 287 00:22:24,050 --> 00:22:26,990 weighs with how much payload we can take ashore. 288 00:22:29,230 --> 00:22:34,730 The bottom line for SST is every pound matters, whether we're talking that from 289 00:22:34,730 --> 00:22:37,970 the perspective of weight savings or how much payload we can take ashore. 290 00:22:39,430 --> 00:22:44,490 For a light but tough hovercraft, the SST's engineers must look to the 291 00:22:44,490 --> 00:22:45,490 of the path. 292 00:22:53,740 --> 00:22:58,460 Engineer Dan Dickrell has traveled to the Military Aviation Museum in Virginia 293 00:22:58,460 --> 00:23:03,060 Beach to discover an incredible piece of aeronautical history. 294 00:23:11,820 --> 00:23:13,820 This is the Yonkers 52. 295 00:23:14,180 --> 00:23:16,500 It was the first cargo plane made out of aluminum. 296 00:23:17,320 --> 00:23:18,660 Look at this thing. 297 00:23:18,900 --> 00:23:19,900 It's immense. 298 00:23:20,520 --> 00:23:22,880 It feels like modern aviation has arrived. 299 00:23:26,960 --> 00:23:32,700 Designed by Ernst Zindel, the Junkers 52 made its maiden flight in 1930. 300 00:23:34,980 --> 00:23:40,000 And its revolutionary all -metal construction meant it could carry an 301 00:23:40,000 --> 00:23:41,580 6 ,000 -pound payload. 302 00:23:42,560 --> 00:23:45,420 A huge upgrade from wooden airframes. 303 00:23:48,040 --> 00:23:53,200 You get a sense of how much space is in here, all of this volume. You can 304 00:23:53,200 --> 00:23:56,860 imagine. All of the supplies that could fit in here and the soldiers getting 305 00:23:56,860 --> 00:23:59,420 ready to fly this plane into battle. 306 00:24:01,940 --> 00:24:06,740 A key factor in making this aircraft capable of carrying all that cargo is 307 00:24:06,740 --> 00:24:07,740 skin. 308 00:24:11,220 --> 00:24:16,340 On the side of the aircraft, we can see this unusual corrugated shape. That's 309 00:24:16,340 --> 00:24:20,940 because... This aircraft is made almost entirely out of aluminum alloy called 310 00:24:20,940 --> 00:24:23,920 Duralumin, which was discovered by Alfred Wilm. 311 00:24:26,880 --> 00:24:31,120 Wilm was a German metallurgist, and his breakthrough alloy would go on to 312 00:24:31,120 --> 00:24:33,160 revolutionize aviation engineering. 313 00:24:36,120 --> 00:24:39,360 When you look at this inspection panel, you get a good sense of how this 314 00:24:39,360 --> 00:24:40,480 aircraft is constructed. 315 00:24:40,800 --> 00:24:44,800 You can actually see the structural elements that compose. 316 00:24:45,200 --> 00:24:50,620 the aircraft, and then also you can see the skin. This is all made of duralumin, 317 00:24:50,760 --> 00:24:55,080 that really, really strong material that enables the plane to carry as much 318 00:24:55,080 --> 00:24:57,100 cargo capacity as possible. 319 00:24:58,620 --> 00:25:02,860 By manufacturing from a metal that was both light enough for flight and strong 320 00:25:02,860 --> 00:25:07,440 enough to hold heavy payloads, the Yunkers proved that airborne cargo 321 00:25:07,440 --> 00:25:08,440 was possible. 322 00:25:09,800 --> 00:25:14,820 This plane, as big as it is, only weighs about 5 ,600 kilograms or about six and 323 00:25:14,820 --> 00:25:15,799 a half tons. 324 00:25:15,800 --> 00:25:17,480 It's a remarkable airplane. 325 00:25:19,940 --> 00:25:24,580 Ville's development of aluminum alloy was crucial to aviation history, but it 326 00:25:24,580 --> 00:25:25,920 was not a smooth process. 327 00:25:26,560 --> 00:25:29,720 It's still quite bendable, and this was very disappointing to Ville. 328 00:25:30,560 --> 00:25:34,320 To build the Navy's lightest and strongest hovercraft of all time. 329 00:25:34,720 --> 00:25:39,020 The engineers behind the shift -to -shore connector will need to use Wilm's 330 00:25:39,020 --> 00:25:41,960 -won innovation in a modern and massive way. 331 00:25:42,440 --> 00:25:45,880 Collection of this material is critical to the success of this vehicle. 332 00:25:48,040 --> 00:25:53,040 When the Junkers 52 debuted in 1930, it was an aviation wonder. 333 00:25:53,820 --> 00:25:58,940 Lighter and tougher than previous planes, the massive carrying capacity 334 00:25:58,940 --> 00:26:03,320 courtesy of Duralumin, an aluminum alloy discovered by German metallurgist 335 00:26:03,320 --> 00:26:04,320 Alfred Wilm. 336 00:26:08,240 --> 00:26:12,940 Engineer Dan Dickrell is demonstrating how this revolutionary material came to 337 00:26:12,940 --> 00:26:16,480 exist. What I have here is a regular piece of aluminum. 338 00:26:16,940 --> 00:26:20,140 Nothing special about it. It's not very strong. It's quite bendable. 339 00:26:20,480 --> 00:26:24,760 This is not very well suited for use in aircraft. 340 00:26:25,340 --> 00:26:29,280 Will knew this, and so what he did is he tried to employ the same techniques 341 00:26:29,280 --> 00:26:35,700 that were used to strength -harden steel. So how we do that is 342 00:26:35,700 --> 00:26:37,020 we create... 343 00:26:38,160 --> 00:26:40,120 An intense source of heat. 344 00:26:40,340 --> 00:26:42,020 In this case, I'm going to use this blowtorch. 345 00:26:42,480 --> 00:26:46,240 And I'm going to heat treat this piece of aluminum. 346 00:26:46,460 --> 00:26:50,540 If we were going to do this on steel, the same technique would be to heat it 347 00:26:50,540 --> 00:26:53,080 to around 700 degrees Celsius. 348 00:26:53,760 --> 00:26:56,760 And then you quickly quench it. 349 00:26:57,380 --> 00:27:02,120 And then we check and see how the strength properties of this aluminum 350 00:27:03,200 --> 00:27:06,320 It's still quite bendable. And this was very disappointing to film. 351 00:27:07,550 --> 00:27:13,450 He had left his laboratory, his tools, and he came back a few days later and re 352 00:27:13,450 --> 00:27:16,570 -examined the aluminum. And what he discovered was this. 353 00:27:17,150 --> 00:27:20,810 It looks the same, but this is age -hardened aluminum. 354 00:27:21,110 --> 00:27:24,290 When I try and bend it, it's a lot tougher. 355 00:27:24,510 --> 00:27:28,050 And this was the magic behind age -hardened aluminum. 356 00:27:28,330 --> 00:27:33,610 That over time, the atomic structure had changed, enhancing its mechanical 357 00:27:33,610 --> 00:27:36,410 properties. And that's what makes this material brilliant. 358 00:27:36,990 --> 00:27:40,870 for aircraft usage is because it is very light and it is very strong. 359 00:27:45,370 --> 00:27:49,370 Vilm's discovery went on to totally transform the aviation industry. 360 00:27:50,590 --> 00:27:54,790 And many modern aircraft are still built with age -hardened aluminum today. 361 00:27:56,330 --> 00:28:01,030 Without the invention of this amazing material, the idea of cargo -carrying 362 00:28:01,030 --> 00:28:02,670 flight would still be impossible. 363 00:28:11,440 --> 00:28:13,780 At the experimental test base in Florida, 364 00:28:14,700 --> 00:28:20,620 Colonel Paul Morita knows that the ability to move more cargo can be key to 365 00:28:20,620 --> 00:28:21,860 success of an operation. 366 00:28:24,720 --> 00:28:27,380 A lighter landing craft is an increased payload. 367 00:28:27,720 --> 00:28:31,800 That means more troops, more vehicles, more combat power, and more sustainment 368 00:28:31,800 --> 00:28:36,160 ashore. The reason that's important is because the quicker that we can get our 369 00:28:36,160 --> 00:28:40,000 combat power ashore, the faster we can prosecute operations. 370 00:28:40,590 --> 00:28:41,630 Once we hit the beach. 371 00:28:44,350 --> 00:28:50,390 By adopting Vilms Aluminum Innovation, the SSC is both strong and light enough 372 00:28:50,390 --> 00:28:54,310 to transport a payload almost 22 times greater than the Yonkers. 373 00:28:55,170 --> 00:28:57,790 A staggering 74 tons. 374 00:28:59,190 --> 00:29:05,690 The SSC allows us to carry extremely heavy loads, like some of our heavier 375 00:29:05,690 --> 00:29:08,830 trucks, some of our artillery systems, and some of our armored vehicles. 376 00:29:10,220 --> 00:29:15,160 At fully loaded capacity, this exceptional hovercraft can move the 377 00:29:15,160 --> 00:29:20,060 weight of 30 Humvees, an essential ability that empowers the troops on the 378 00:29:20,060 --> 00:29:21,060 lines. 379 00:29:22,040 --> 00:29:25,460 These vehicles are important to our operations because it gives us mobility, 380 00:29:25,740 --> 00:29:29,940 gives us speed, and inherent in that is extra firepower as well. 381 00:29:34,360 --> 00:29:36,140 At the factory in New Orleans. 382 00:29:38,090 --> 00:29:42,430 The engineering team is working with this amazing metal as they prepare 383 00:29:42,430 --> 00:29:44,550 vehicle to roll off the production line. 384 00:29:46,370 --> 00:29:51,270 So to construct the hull and the above -deck modules, we use 5083 aluminum. 385 00:29:52,450 --> 00:29:57,330 It's a choice that's undoubtedly influenced by Junker's pioneering cargo 386 00:29:59,510 --> 00:30:02,370 Aircraft and the SSD share a similar design. 387 00:30:02,610 --> 00:30:04,710 They're both very, very sensitive to weight. 388 00:30:05,900 --> 00:30:10,760 The way that aircraft are constructed using aluminum, just very similar to 389 00:30:11,260 --> 00:30:14,880 the same kind of structural engineering approach, the same type of materials. 390 00:30:17,200 --> 00:30:22,520 But the demands placed on the SSE means strength is just as important as weight. 391 00:30:24,360 --> 00:30:29,000 The SSE is designed so that you can carry very, very heavy payloads, 392 00:30:29,000 --> 00:30:30,840 the Abrams M1A1 tank. 393 00:30:31,040 --> 00:30:34,320 That tank needs to be able to roll on top of the SSE. 394 00:30:35,290 --> 00:30:39,030 The modules that we designed for the SSE need to be able to withstand those 395 00:30:39,030 --> 00:30:40,030 kinds of loads. 396 00:30:42,730 --> 00:30:47,350 In this cell, we're building up the fixed and deployable ramps for the SSE. 397 00:30:47,910 --> 00:30:51,330 You can see the stiffeners that are used to strengthen up the module. 398 00:30:51,730 --> 00:30:56,190 We use 5083 aluminum plate and extrusion to build these and then install them on 399 00:30:56,190 --> 00:30:57,190 the craft. 400 00:30:58,070 --> 00:31:01,350 Collection of this material is critical to the success of this vehicle. 401 00:31:09,580 --> 00:31:13,600 Engineers have designed an amphibious vehicle more capable than any other. 402 00:31:14,660 --> 00:31:19,520 But working in destructive offshore conditions presents plenty more 403 00:31:20,980 --> 00:31:24,860 When you look at the different environments that we're called upon to 404 00:31:24,860 --> 00:31:28,720 in, it's some of the harshest environments on the globe. 405 00:31:30,000 --> 00:31:34,640 To find answers, they must turn to the great innovators of the past. 406 00:31:35,210 --> 00:31:39,370 I'm just kind of in awe of my engineering ancestors. 407 00:31:46,330 --> 00:31:50,950 The Ship to Shore connector is the most advanced hovercraft on the planet. 408 00:31:53,810 --> 00:31:58,470 Built to deliver U .S. troops and heavy cargo into hard -to -reach locations, 409 00:31:58,770 --> 00:32:01,650 it's the ultimate amphibious vehicle. 410 00:32:04,450 --> 00:32:08,350 Driven by a pair of propellers that measure almost 12 feet across, 411 00:32:10,190 --> 00:32:16,730 the SSD can hover on a six -foot cushion of air and fly across the water 412 00:32:16,730 --> 00:32:21,950 straight on to 70 % of the planet's coastlines to deliver its outsized 413 00:32:21,950 --> 00:32:26,030 an achievement unmatched by any other landing craft. 414 00:32:32,140 --> 00:32:37,960 But if this brand new vehicle is to achieve its objectives once deployed, it 415 00:32:37,960 --> 00:32:41,400 to be tough enough to survive the rigors of military operation. 416 00:32:42,220 --> 00:32:48,860 When you look at the different environments that we're called 417 00:32:48,860 --> 00:32:53,800 upon to operate in, it's some of the harshest environments on the globe. 418 00:32:54,340 --> 00:32:58,880 And SSC has to deliver, has to be able to take Marines and their cargo from the 419 00:32:58,880 --> 00:32:59,920 ship to the shore. 420 00:33:01,710 --> 00:33:06,450 To function in near -impossible conditions characterized by corrosive 421 00:33:06,450 --> 00:33:12,450 water, abrasive sand, and punishing temperature extremes, the SSC must be 422 00:33:12,450 --> 00:33:13,450 to last. 423 00:33:14,690 --> 00:33:20,590 We have to consider our ability to maintain the craft as it operates over 424 00:33:20,590 --> 00:33:24,590 -year service life. We're talking about wear and tear on the vehicle, individual 425 00:33:24,590 --> 00:33:28,530 components. how long they last, how durable they are. 426 00:33:28,970 --> 00:33:33,490 Each component has to have that factor of consideration before we install it or 427 00:33:33,490 --> 00:33:35,570 incorporate it into the design of FSC. 428 00:33:37,350 --> 00:33:42,070 For inspiration on marine durability, engineers must look to history's great 429 00:33:42,070 --> 00:33:43,070 innovators. 430 00:33:51,670 --> 00:33:53,510 In Evansville, Indiana. 431 00:33:53,910 --> 00:33:54,910 Hi, Rick. 432 00:33:55,130 --> 00:33:57,130 Hello, Mark. I've got to put this on. 433 00:33:57,410 --> 00:34:02,270 Okay. Professor Mark Valenzuela is about to take a once -in -a -lifetime ride on 434 00:34:02,270 --> 00:34:04,210 an icon of military engineering. 435 00:34:07,550 --> 00:34:14,449 Just thinking about 36 men kind of anticipating their arrival onto Omaha 436 00:34:14,449 --> 00:34:18,889 Beach in a boat like this is kind of amazing. 437 00:34:21,790 --> 00:34:23,969 This is an LCVP. 438 00:34:26,030 --> 00:34:31,770 or a landing craft vehicle personnel, one of the most important vessels of 439 00:34:31,770 --> 00:34:32,770 War II. 440 00:34:39,870 --> 00:34:40,469 Built 441 00:34:40,469 --> 00:34:50,469 to 442 00:34:50,469 --> 00:34:54,550 navigate the challenges of shallow waters and land troops directly on the 443 00:34:54,550 --> 00:34:55,550 of Europe, 444 00:34:57,940 --> 00:35:04,240 The LCVP was a game -changing innovation, but its design was far from 445 00:35:07,740 --> 00:35:13,740 The original ones were made out of wood and wood panels, so that would need to 446 00:35:13,740 --> 00:35:17,580 be pieced together using screws and bolts. 447 00:35:18,300 --> 00:35:23,660 Anytime you create that hole in the material, you're really compromising the 448 00:35:23,660 --> 00:35:24,720 integrity of the material. 449 00:35:27,340 --> 00:35:32,640 To improve the durability of the LCVP, military engineers needed a new 450 00:35:36,660 --> 00:35:41,320 Luckily, an inventor by the name of Gaines Slater had made a discovery that 451 00:35:41,320 --> 00:35:42,600 could help solve the problem. 452 00:35:45,260 --> 00:35:50,320 By bonding glass fibers inside a hardening resin, Slater invented a 453 00:35:50,320 --> 00:35:52,160 plastic known as fiberglass. 454 00:35:55,740 --> 00:36:00,260 Stronger and lighter than steel, and highly resistant to rot and extreme 455 00:36:00,260 --> 00:36:01,260 temperatures. 456 00:36:02,840 --> 00:36:07,420 It was an ideal solution for building a new and improved generation of this 457 00:36:07,420 --> 00:36:08,740 iconic landing craft. 458 00:36:10,480 --> 00:36:17,060 Here it is, the fiberglass LCVP, and it is a magnificent boat. 459 00:36:19,200 --> 00:36:21,420 First deployed during the Korean War. 460 00:36:22,030 --> 00:36:27,450 The redesigned LCVP is the earliest known military vessel to be mass 461 00:36:27,450 --> 00:36:29,230 from fiber -reinforced plastic. 462 00:36:30,930 --> 00:36:36,410 We can kind of get that sense of that fiberglass, that hollow thumping sound. 463 00:36:36,670 --> 00:36:37,930 This is in beautiful shape. 464 00:36:41,430 --> 00:36:46,710 The introduction of this incredible composite material offered the new LCVP 465 00:36:46,710 --> 00:36:47,710 number of advantages. 466 00:36:50,280 --> 00:36:54,900 In terms of that manufacturing with fiberglass, we can make it as big as we 467 00:36:54,900 --> 00:36:58,640 to. So we aren't limited by the size of the planks that we would use in regular 468 00:36:58,640 --> 00:36:59,640 plywood. 469 00:36:59,800 --> 00:37:05,280 And so because we can fabricate it in fewer pieces and fewer joints, there's 470 00:37:05,280 --> 00:37:09,120 going to be fewer weaknesses associated with all of those joints. 471 00:37:11,000 --> 00:37:16,120 The radical new strength available via fiberglass produced a more durable, 472 00:37:16,120 --> 00:37:18,280 -hitting LCVP than ever before. 473 00:37:19,560 --> 00:37:25,020 To build on its remarkable success, the engineers behind the ship -to -shore 474 00:37:25,020 --> 00:37:27,300 connector will need to take Slater's lead. 475 00:37:27,600 --> 00:37:31,740 Using composites allows us to achieve some very complex arrow shapes. 476 00:37:32,120 --> 00:37:35,660 And adapt his innovative idea for the 21st century. 477 00:37:37,020 --> 00:37:41,560 In order to build the most capable and durable hovercraft the U .S. Navy has 478 00:37:41,560 --> 00:37:44,720 ever seen, engineers need the right materials. 479 00:37:45,840 --> 00:37:48,820 the team is looking to their forefathers for inspiration. 480 00:37:51,040 --> 00:37:55,860 When military engineers needed to redesign the Landing Craft Vehicle 481 00:37:56,000 --> 00:38:02,060 or LCVP, in the 1950s, they turned from plywood to fiberglass. 482 00:38:03,020 --> 00:38:07,300 So we can kind of imagine plywood panels that would be used to form the shape of 483 00:38:07,300 --> 00:38:12,080 this hole. These two pieces of paper just kind of butted against each other. 484 00:38:12,280 --> 00:38:16,420 We need some way to be able to hold these panels together. 485 00:38:16,700 --> 00:38:20,800 What we could do is kind of simulate these mechanical fasteners just using 486 00:38:20,800 --> 00:38:25,460 staples. But once I start to introduce these staples, those holes then become 487 00:38:25,460 --> 00:38:28,700 these points of weakness in this material. 488 00:38:28,940 --> 00:38:33,310 It might actually be easy for us to be able to... break them open like this, 489 00:38:33,590 --> 00:38:37,810 especially along those joints. And so you'll notice that the failure is 490 00:38:37,810 --> 00:38:38,810 all along that. 491 00:38:39,510 --> 00:38:43,130 So this is one of the weaknesses that we see with the use of plywood. 492 00:38:43,430 --> 00:38:48,430 The advantage, of course, with fiberglass is to be able to use one 493 00:38:48,430 --> 00:38:52,590 sheet that doesn't have to rely on any of these joints or any of these 494 00:38:52,590 --> 00:38:53,850 mechanical fasteners. 495 00:38:55,530 --> 00:39:00,650 Thanks to the introduction of reinforced plastic, many fiberglass LCVPs are 496 00:39:00,650 --> 00:39:04,330 still seaworthy, while none of their plywood predecessors are. 497 00:39:05,310 --> 00:39:11,690 Taking a look at this marvel of engineering from the 1950s, and I'm just 498 00:39:11,690 --> 00:39:14,590 in awe of my engineering ancestors. 499 00:39:25,530 --> 00:39:31,470 Today, at the production facility in New Orleans, Ryan and the team are relying 500 00:39:31,470 --> 00:39:35,390 on fiber -reinforced plastics for key components of the SSC. 501 00:39:36,770 --> 00:39:41,890 So we're using composite technology, the latest epoxy and carbon fiber. We use 502 00:39:41,890 --> 00:39:46,030 that for our lift band volute, the bow thruster, our drive shaft, the prop 503 00:39:46,270 --> 00:39:48,070 the rudders, as well as the propellers themselves. 504 00:39:49,490 --> 00:39:54,170 Composites are very corrosion resistant by their nature, so they're able to 505 00:39:54,170 --> 00:39:58,450 withstand the very difficult operating environment, for instance, salt water 506 00:39:58,450 --> 00:40:00,270 those kind of heavy humidity environments. 507 00:40:01,430 --> 00:40:07,430 And just like the pioneering landing craft of the past, the SSC's durability 508 00:40:07,430 --> 00:40:10,190 improved through its use of these innovative materials. 509 00:40:12,390 --> 00:40:16,750 Using composites allows us to reduce the total part count on this craft and also 510 00:40:16,750 --> 00:40:20,830 allows us to achieve some very complex arrow shapes, such as the lift band 511 00:40:20,830 --> 00:40:24,410 balloon that you see behind me. And we're allowed to do that with fewer 512 00:40:24,610 --> 00:40:28,930 We were able to achieve these shapes by molding the parts all in one. 513 00:40:29,130 --> 00:40:33,370 So with having fewer parts, that's less parts that you have to maintain, so that 514 00:40:33,370 --> 00:40:34,710 improves the lifetime of the craft. 515 00:40:40,080 --> 00:40:45,560 Thanks to the impressive engineering behind this amazing machine, the 516 00:40:45,560 --> 00:40:48,820 of moving from ship to shore can be easily conquered. 517 00:40:51,580 --> 00:40:56,240 The SSC is absolutely one of the most amazing vehicles on the ocean, or the 518 00:40:56,240 --> 00:41:00,220 for that matter. This vehicle can do things that no other vehicle can do. 519 00:41:05,580 --> 00:41:09,860 The capability of the SSC is amazing. It's definitely in a league of its own. 520 00:41:10,160 --> 00:41:14,340 It's next generation, and it's going to allow the Marine Corps to get combat 521 00:41:14,340 --> 00:41:17,900 power ashore much, much more quickly than currently. 522 00:41:19,100 --> 00:41:25,800 By looking to the pioneers of the path for inspiration, adapting 523 00:41:25,800 --> 00:41:26,800 their ideas, 524 00:41:27,900 --> 00:41:32,900 updating their designs, and overcoming huge challenges, 525 00:41:35,950 --> 00:41:40,250 The Ship to Shore Connectors team has built a boundary -pushing piece of 526 00:41:40,250 --> 00:41:46,470 amphibious engineering and succeeded in making the impossible 527 00:41:46,470 --> 00:41:48,270 possible. 528 00:41:49,150 --> 00:41:53,010 The Ship to Shore Connector platform is absolutely one of the most amazing 529 00:41:53,010 --> 00:41:54,850 platforms you'll ever see at sea. 530 00:41:55,090 --> 00:41:57,710 It's simply in a class of its own. 531 00:41:57,760 --> 00:42:02,310 Repair and Synchronization by Easy Subtitles Synchronizer 1.0.0.0 50470
