251 00:14:23,680 --> 00:14:27,180 And then how do you do that in a fuel-efficient way? 252 00:14:27,180 --> 00:14:28,720 For inspiration, 253 00:14:28,720 --> 00:14:31,350 the team looked to the engineers of the past. 254 00:14:42,900 --> 00:14:48,440 Mechanical engineer Dan Dickrell is in Niagara, New York. 255 00:14:48,440 --> 00:14:49,940 This facility is 256 00:14:49,940 --> 00:14:52,510 the bell aerospace company airplane factory. 257 00:14:52,510 --> 00:14:55,340 It's a really impressive piece of history 258 00:14:55,340 --> 00:14:59,650 in terms of airplane manufacturing. 259 00:14:59,650 --> 00:15:01,780 He's gained exclusive access to the site 260 00:15:01,780 --> 00:15:05,390 of the greatest advancement in personal flight. 261 00:15:05,390 --> 00:15:08,560 It's a cool, cool experience to be here right now. 262 00:15:08,560 --> 00:15:12,030 In the 1950s, bell aerospace was attempting to develop 263 00:15:12,030 --> 00:15:14,760 a flight-suit for the U.S. military, 264 00:15:14,760 --> 00:15:18,070 an innovation for the soldiers of the future. 265 00:15:18,070 --> 00:15:20,030 Bell challenged its engineers... 266 00:15:20,040 --> 00:15:22,040 "how do you make a person fly?" 267 00:15:24,610 --> 00:15:26,610 Aeronautical engineer Wendell Moore 268 00:15:26,610 --> 00:15:29,980 believed rocket propulsion was the solution. 269 00:15:29,980 --> 00:15:32,780 In the late '50s, he developed an incredible piece 270 00:15:32,780 --> 00:15:34,550 of military equipment... 271 00:15:39,460 --> 00:15:41,960 The first controllable rocket pack. 272 00:15:45,660 --> 00:15:48,500 So, this is it. It's the bell rocket belt. 273 00:15:51,530 --> 00:15:56,140 It's pretty cool to be up close and personal to this very basic, 274 00:15:56,140 --> 00:15:57,910 yet historic thing. This is not a model. 275 00:15:57,910 --> 00:15:59,540 This actually flew. 276 00:16:02,650 --> 00:16:03,880 Check this thing out. 277 00:16:03,880 --> 00:16:06,950 It's got a polystyrene and fiberglass harness... 278 00:16:06,950 --> 00:16:08,550 That's where the pilot goes. 279 00:16:08,550 --> 00:16:10,020 We see these controls. 280 00:16:10,020 --> 00:16:13,020 There's throttle, there's directional thrusters. 281 00:16:13,020 --> 00:16:16,020 The aluminum foil sort of hoses that come down... 282 00:16:16,030 --> 00:16:19,760 This is actually the rocket... The rocket nozzles themselves. 283 00:16:19,760 --> 00:16:21,060 We swing around the back, we can 284 00:16:21,060 --> 00:16:23,530 Se there's these three storage tanks. 285 00:16:23,530 --> 00:16:25,870 There's nitrogen in there and hydrogen peroxide 286 00:16:25,870 --> 00:16:28,340 in the two outer tanks. 287 00:16:28,340 --> 00:16:31,110 Compressed nitrogen gas in the central chamber 288 00:16:31,110 --> 00:16:35,780 pushes hydrogen peroxide out of the two surrounding tanks, 289 00:16:35,780 --> 00:16:39,910 bringing it into contact with a silver catalyst. 290 00:16:39,920 --> 00:16:41,850 This causes the hydrogen peroxide 291 00:16:41,850 --> 00:16:45,750 to instantly decompose into water and oxygen, 292 00:16:45,760 --> 00:16:48,020 sparking a huge reaction. 293 00:16:50,190 --> 00:16:53,630 That hydrogen peroxide reaction is really, really energetic, 294 00:16:53,630 --> 00:16:55,160 creates a lot of heat. 295 00:16:55,160 --> 00:16:56,930 So that water gets turned into steam, 296 00:16:56,930 --> 00:17:00,370 expands through 5,000 times its volume, 297 00:17:00,370 --> 00:17:05,140 and exits these nozzles at over a thousand meters per second. 298 00:17:05,140 --> 00:17:07,240 This almighty force was powerful enough 299 00:17:07,240 --> 00:17:09,210 to life man from earth. 300 00:17:11,210 --> 00:17:15,650 Extraordinary energy created by chemistry. 301 00:17:15,650 --> 00:17:19,390 So what I have here is effectively a small car 302 00:17:19,390 --> 00:17:21,760 that will be rocket-propelled. 303 00:17:21,760 --> 00:17:27,390 All right, so let's draw in some hydrogen peroxide. 304 00:17:27,400 --> 00:17:30,900 I'm going to add this to these silver spheres. 305 00:17:30,900 --> 00:17:32,930 This makes a lot of heat. 306 00:17:32,940 --> 00:17:34,540 We can see the reaction is happening. 307 00:17:34,540 --> 00:17:37,640 It is propelling the car down the table. 308 00:17:37,640 --> 00:17:40,440 We see the hot gasses coming out, 309 00:17:40,440 --> 00:17:42,080 and even though it's going slowly, 310 00:17:42,080 --> 00:17:43,680 it's the same premise 311 00:17:43,680 --> 00:17:46,450 that's used in Wendell Moore's rocket belt. 312 00:17:46,450 --> 00:17:50,450 We can harness the power of a chemical reaction 313 00:17:50,450 --> 00:17:53,390 and make all sorts of mechanical motion happen. 314 00:17:53,390 --> 00:17:56,890 Science. 315 00:17:56,890 --> 00:17:59,690 Just like the jet suit's team of engineers, 316 00:17:59,700 --> 00:18:03,000 Wendell Moore used the most astonishing science of his day 317 00:18:03,000 --> 00:18:05,100 to launch man into the air. 318 00:18:07,500 --> 00:18:12,140 But in 1961, the bell rocket belt did just that. 319 00:18:15,380 --> 00:18:18,410 Propelling its pilot around 32 feet high, 320 00:18:18,410 --> 00:18:22,980 it reached a controlled 34 miles per hour. 321 00:18:22,990 --> 00:18:25,820 But despite impressive aerial displays, 322 00:18:25,820 --> 00:18:27,720 Wendell Moore's space-age invention 323 00:18:27,720 --> 00:18:29,990 had one major limitation. 324 00:18:32,090 --> 00:18:34,460 The bell rocket belt was not successful in the end 325 00:18:34,460 --> 00:18:36,060 because its thrust-to-weight ratio 326 00:18:36,070 --> 00:18:37,600 was just not good enough. 327 00:18:37,600 --> 00:18:40,470 You only had about 20 seconds of flight time in this version, 328 00:18:40,470 --> 00:18:42,800 and that was not practical in the battlefield. 329 00:18:42,810 --> 00:18:44,140 But Wendell Moore had proven that 330 00:18:44,140 --> 00:18:45,610 personal flight was possible. 331 00:18:45,610 --> 00:18:47,170 It's just that the propulsion system 332 00:18:47,180 --> 00:18:48,880 is what needed some tweaking. 333 00:19:00,920 --> 00:19:02,260 Inventor Richard Browning 334 00:19:02,260 --> 00:19:03,760 and his team of engineers 335 00:19:03,760 --> 00:19:06,760 owe a huge debt to the early rocket-men, 336 00:19:06,760 --> 00:19:08,160 who unknowingly ruled out 337 00:19:08,160 --> 00:19:10,900 the inefficient chemical power of hydrogen peroxide 338 00:19:10,900 --> 00:19:14,430 as a propulsion solution. 339 00:19:14,440 --> 00:19:18,010 But another technology powered by kerosene stood out... 340 00:19:20,010 --> 00:19:22,480 The micro-jet engine. 341 00:19:22,480 --> 00:19:24,880 It didn't take us very long to really settle on jet engines 342 00:19:24,880 --> 00:19:28,220 as a very likely good solution. 343 00:19:28,220 --> 00:19:31,690 It's a very small, lightweight form of thrust relative 344 00:19:31,690 --> 00:19:33,620 to how much it produces. 345 00:19:33,620 --> 00:19:36,790 The power involved is enough to take that mass supersonic, 346 00:19:36,790 --> 00:19:39,930 and the fuel in kerosene is actually extremely energy-dense, 347 00:19:39,930 --> 00:19:41,630 and yet at the same time, not very volatile 348 00:19:41,630 --> 00:19:43,400 and not really that prone to explosion. 349 00:19:43,400 --> 00:19:47,270 It's actually pretty safe as fuels go. 350 00:19:47,270 --> 00:19:50,440 At arguably the most prestigious aeronautical event 351 00:19:50,440 --> 00:19:53,740 in the world, 352 00:19:53,740 --> 00:19:57,740 80,000 spectators and top aircraft specialists 353 00:19:57,750 --> 00:19:59,780 flock to Farnborough air show 354 00:19:59,780 --> 00:20:01,750 to witness the latest innovations... 355 00:20:06,490 --> 00:20:09,320 ...including the fastest body-controlled jet suit 356 00:20:09,330 --> 00:20:14,900 in the world, powered by over 315 pounds of thrust, 357 00:20:14,900 --> 00:20:18,630 produced by five innovative micro-jets, 358 00:20:18,630 --> 00:20:24,440 with the potential to one day fly 3,200 feet in the sky. 359 00:20:24,440 --> 00:20:27,340 So, you come down here. We're going to stop about here. 360 00:20:27,340 --> 00:20:29,810 Today, pioneering pilot Richard Browning 361 00:20:29,810 --> 00:20:32,280 prepares to take flight. 362 00:20:32,280 --> 00:20:34,050 You're going to take off and go that way. 363 00:20:34,050 --> 00:20:37,150 - Yep, and you're going to go... - I'm going to go that way. 364 00:20:37,150 --> 00:20:39,490 So, just how do these tiny jet engines 365 00:20:39,490 --> 00:20:42,420 produce enough thrust to get Richard off the ground 366 00:20:42,420 --> 00:20:45,960 and showboating for his captive audience? 367 00:20:45,960 --> 00:20:48,660 If you can imagine, it's like having two Ferraris 368 00:20:48,660 --> 00:20:51,530 at full power, acting on the human body. 369 00:20:51,530 --> 00:20:54,100 That's the amount of power we've got going through us. 370 00:20:54,100 --> 00:20:58,070 It will take some custom work and a healthy dose of kerosene 371 00:20:58,070 --> 00:21:01,510 to make this impossible engineering a reality. 372 00:21:17,430 --> 00:21:19,460 The micro-jet engine. 373 00:21:19,460 --> 00:21:21,860 The tiny solution to a big problem 374 00:21:21,860 --> 00:21:24,330 facing the revolutionary jet suit 375 00:21:24,330 --> 00:21:27,570 and the audacious engineers behind it. 376 00:21:27,570 --> 00:21:29,970 It didn't take us very long to really settle on jet engines 377 00:21:29,970 --> 00:21:32,710 as a very likely good solution. 378 00:21:32,710 --> 00:21:34,810 This kerosene-fueled powerhouse 379 00:21:34,810 --> 00:21:37,380 is not only a comparatively safe option, 380 00:21:37,380 --> 00:21:39,810 but an extremely forceful one, too. 381 00:21:42,080 --> 00:21:46,450 What's expelled from the back of a jet engine is mainly air. 382 00:21:46,460 --> 00:21:50,460 In this case, ejected at 1,600 miles per hour. 383 00:21:53,860 --> 00:21:57,260 The super-powered process starts at the engine's front. 384 00:21:57,270 --> 00:21:59,330 Air flows in through an inlet. 385 00:21:59,340 --> 00:22:01,970 It's compressed, combined with the kerosene fuel, 386 00:22:01,970 --> 00:22:07,010 and ignited, which produces a hot air flow or gas. 387 00:22:07,010 --> 00:22:10,040 Forced through a nozzle, it rotates a turbine, 388 00:22:10,050 --> 00:22:14,610 which helps ingest more air, generating immense thrust. 389 00:22:16,590 --> 00:22:18,620 The team has spent months developing 390 00:22:18,620 --> 00:22:20,190 customized jet engines, 391 00:22:20,190 --> 00:22:24,320 or gas turbines, at their secret test facility. 392 00:22:24,330 --> 00:22:25,830 So, this is the solution. 393 00:22:25,830 --> 00:22:28,530 This represents the ultimate in gas turbine technology. 394 00:22:28,530 --> 00:22:30,800 It spins about 117,000 rpm, 395 00:22:30,800 --> 00:22:34,670 so we're looking at nearly 2,000 revolutions every second. 396 00:22:34,670 --> 00:22:39,840 The gas is coming out the back at over 1,700 miles per hour 397 00:22:39,840 --> 00:22:42,040 at about 700 degrees Celsius. 398 00:22:42,040 --> 00:22:44,180 This is, in terms of brute power, 399 00:22:44,180 --> 00:22:45,680 the highest power density 400 00:22:45,680 --> 00:22:48,480 that you can get out of any particular kind of engine. 401 00:22:48,480 --> 00:22:50,850 To put the power of these engines into perspective, 402 00:22:50,850 --> 00:22:52,790 when we've got all of our engines integrated on the suit, 403 00:22:52,790 --> 00:22:55,420 we're producing nearly a thousand horsepower. 404 00:22:55,420 --> 00:22:58,260 And if you can imagine, it's like having two Ferraris 405 00:22:58,260 --> 00:23:01,190 at full power acting on the human body. 406 00:23:01,200 --> 00:23:03,163 That's the amount of power we've got going through us. 407 00:23:03,170 --> 00:23:05,500 And that's all being produced by these very lightweight 408 00:23:05,500 --> 00:23:10,300 gas turbines, each weighing no more than 1.85 kilos. 409 00:23:12,110 --> 00:23:14,980 According to design engineer Sam Rogers, 410 00:23:14,980 --> 00:23:17,640 this ingenious compact, lightweight solution 411 00:23:17,650 --> 00:23:21,420 radically increases flying time. 412 00:23:21,420 --> 00:23:26,520 The micro-turbine allows us to have a high level of thrust 413 00:23:26,520 --> 00:23:28,620 for a much longer period of time. 414 00:23:28,620 --> 00:23:31,460 We're now into the minutes rather than seconds. 415 00:23:31,460 --> 00:23:34,090 It means we can have reasonable flight time 416 00:23:34,100 --> 00:23:36,660 whilst still having a reasonable fuel efficiency 417 00:23:36,670 --> 00:23:40,300 at the same time. 418 00:23:40,300 --> 00:23:41,700 In little more than a year, 419 00:23:41,700 --> 00:23:44,840 the team has gone from barely getting off the ground 420 00:23:44,840 --> 00:23:47,240 to 4-minute-long flights. 421 00:23:53,650 --> 00:23:56,150 But once airborne, they face another seemingly 422 00:23:56,150 --> 00:23:59,120 impossible problem... steering. 423 00:23:59,120 --> 00:24:01,490 You're not using wings, elevators, rudder. 424 00:24:01,490 --> 00:24:03,060 We're got none of that. 425 00:24:03,060 --> 00:24:06,090 We honestly didn't have an idea of how we were going to do this. 426 00:24:09,130 --> 00:24:12,630 But just how do you control and steer over 1,000 horsepower 427 00:24:12,630 --> 00:24:14,370 strapped to your body? 428 00:24:16,870 --> 00:24:19,910 We honestly didn't have an idea of how we were going to do this. 429 00:24:19,910 --> 00:24:22,440 A solution to their seemingly impossible problem 430 00:24:22,440 --> 00:24:25,010 lies with the innovators of the past. 431 00:24:33,220 --> 00:24:38,460 The space & rocket center in Huntsville, Alabama... 432 00:24:38,460 --> 00:24:41,500 The home of America's first space program. 433 00:24:43,630 --> 00:24:46,130 Veteran astronaut general Bob Stewart has spent 434 00:24:46,130 --> 00:24:48,670 almost 300 hours in space. 435 00:24:52,840 --> 00:24:55,510 Stewart was the first active-duty army pilot 436 00:24:55,510 --> 00:24:58,550 to ever make a space flight. 437 00:24:58,550 --> 00:25:01,550 When you're there, it's a complete sense of freedom. 438 00:25:01,550 --> 00:25:03,450 You can have lunch on the ceiling, 439 00:25:03,450 --> 00:25:06,920 you can lift huge weights, you can get on the side wall 440 00:25:06,920 --> 00:25:08,660 and jump through the middle of the cabin 441 00:25:08,660 --> 00:25:12,760 and try to grab peanut M&Ms as you go. 442 00:25:12,760 --> 00:25:14,360 However, working in space 443 00:25:14,360 --> 00:25:18,130 can also be a dangerous business. 444 00:25:18,130 --> 00:25:19,730 This is mission control Houston. 445 00:25:19,740 --> 00:25:22,540 The hatch is now open. 446 00:25:22,540 --> 00:25:24,800 Astronauts often had to conduct repairs 447 00:25:24,810 --> 00:25:28,280 outside the safe confines of the shuttle... 448 00:25:28,280 --> 00:25:29,480 Mark, we got about 60 to go. 449 00:25:29,480 --> 00:25:31,510 60 centimeters. 450 00:25:31,510 --> 00:25:35,380 ...and were tethered to prevent them from floating away, 451 00:25:35,380 --> 00:25:38,320 at the cost of maneuverability. 452 00:25:38,320 --> 00:25:41,350 The primary problem with being tethered in space 453 00:25:41,360 --> 00:25:42,990 is that restriction. 454 00:25:42,990 --> 00:25:45,460 I want to go out here to fix something, 455 00:25:45,460 --> 00:25:47,890 and my tether is 3 feet too short, 456 00:25:47,900 --> 00:25:50,330 and I'm sitting here so close, and yet so far. 457 00:26:00,440 --> 00:26:03,640 You get to thinking, "what if I could figure some way to do" 458 00:26:03,650 --> 00:26:08,620 without that tether, so that I'm no longer constrained?" 459 00:26:08,620 --> 00:26:11,720 Yeah, that's it, and you can head toward the airlock. 460 00:26:13,990 --> 00:26:17,290 In 1984, NASA engineer Charles E. Whitsett 461 00:26:17,290 --> 00:26:20,790 came up with a solution that would free up the astronauts 462 00:26:20,800 --> 00:26:22,760 and allow them to make untethered flights 463 00:26:22,760 --> 00:26:25,930 outside the craft, 464 00:26:25,930 --> 00:26:31,440 an invention that could help out the jet suit team, 465 00:26:31,440 --> 00:26:37,340 known as the manned maneuvering unit, or M.M.U. 466 00:26:37,350 --> 00:26:40,810 With this machine, we could fly freely, 467 00:26:40,820 --> 00:26:43,620 and it is just the most delightful flying machine 468 00:26:43,620 --> 00:26:45,350 that I have ever encountered. 469 00:26:47,720 --> 00:26:50,460 It is the easiest thing I have ever operated. 470 00:26:50,460 --> 00:26:51,930 I told the people on the ground 471 00:26:51,930 --> 00:26:54,190 that I could thread a needle with this thing. 472 00:27:00,500 --> 00:27:01,940 It allowed Bob Stewart and his fellow astronauts 473 00:27:01,940 --> 00:27:04,840 to make the first-ever untethered space walk. 474 00:27:06,910 --> 00:27:08,070 Good boy. 475 00:27:08,080 --> 00:27:10,880 Thank you for bringing me home. 476 00:27:10,880 --> 00:27:13,550 The M.M.U. Gave astronauts complete control 477 00:27:13,550 --> 00:27:17,020 in the most unforgiving of environments. 478 00:27:17,020 --> 00:27:19,650 If I want to roll the vehicle, 479 00:27:19,660 --> 00:27:21,250 I roll it with this axis right here, 480 00:27:21,260 --> 00:27:24,020 just with those fingertip-type motions. 481 00:27:24,030 --> 00:27:27,590 If I want to pitch it, it's a rotation like this. 482 00:27:27,600 --> 00:27:30,660 So, by combinations of these movements, 483 00:27:30,670 --> 00:27:32,500 I can make the machine do anything 484 00:27:32,500 --> 00:27:35,800 I want to as far as the attitude that I'm in. 485 00:27:35,800 --> 00:27:39,270 If I want to go somewhere, I do that with my left hand... 486 00:27:39,270 --> 00:27:41,780 The translational hand controller. 487 00:27:41,780 --> 00:27:43,840 And it is a push-in-the-direction-you-want- 488 00:27:43,850 --> 00:27:45,280 to-go type of control. 489 00:27:45,280 --> 00:27:47,610 This would back me up, this would go forward, 490 00:27:47,620 --> 00:27:51,420 this slide me to the right, slide me to the left, 491 00:27:51,420 --> 00:27:53,490 and push me up or down. 492 00:27:55,690 --> 00:27:57,420 This mind-blowing maneuverability 493 00:27:57,430 --> 00:27:59,930 was down to precision thrust control. 494 00:28:02,030 --> 00:28:05,630 Three thrusters located on each of the suit's eight corners 495 00:28:05,630 --> 00:28:07,530 were oriented at different angles, 496 00:28:07,540 --> 00:28:11,810 producing intricate and effortless steering. 497 00:28:11,810 --> 00:28:13,570 26 pounds of nitrogen 498 00:28:13,580 --> 00:28:18,210 provided propulsion for a six-hour flight. 499 00:28:18,210 --> 00:28:20,080 I felt very relaxed in this thing, 500 00:28:20,080 --> 00:28:24,380 and it was like sitting in an easy chair. 501 00:28:24,390 --> 00:28:27,820 After three space shuttle missions, 502 00:28:27,820 --> 00:28:30,020 NASA retired the M.M.U. 503 00:28:30,030 --> 00:28:32,330 It makes me sad to see 504 00:28:32,330 --> 00:28:35,700 that NASA made the decision to discontinue it. 505 00:28:35,700 --> 00:28:37,730 And about six of us guys went to the bar 506 00:28:37,730 --> 00:28:41,940 and had a beer and cried about it 507 00:28:41,940 --> 00:28:45,610 because it's a lovely flying machine. 508 00:28:45,610 --> 00:28:49,210 Though successful, ultimately untethered flights in space 509 00:28:49,210 --> 00:28:52,250 were deemed too risky. 510 00:28:52,250 --> 00:28:57,520 But the M.M.U. Will forever remain an icon of space flight. 511 00:28:57,520 --> 00:29:01,190 When you reach far and you try to grasp things 512 00:29:01,190 --> 00:29:06,390 so far beyond your capability, and you make it work, 513 00:29:06,390 --> 00:29:09,430 that is a great, great feeling. 514 00:29:12,130 --> 00:29:14,000 Richard Browning and his team are familiar 515 00:29:14,000 --> 00:29:16,170 with that sense of triumph. 516 00:29:16,170 --> 00:29:20,040 It's exciting and exhilarating and certainly focused the mind. 517 00:29:20,040 --> 00:29:23,110 They'll draw inspiration from the revolutionary ideas 518 00:29:23,110 --> 00:29:27,580 behind the M.M.U. To launch man into the future. 519 00:29:46,640 --> 00:29:49,600 Much like the manned maneuvering unit of the '80s, 520 00:29:49,600 --> 00:29:51,140 Richard Browning and his team 521 00:29:51,140 --> 00:29:56,310 are also directing thrust to maneuver their jet suit. 522 00:29:56,310 --> 00:30:00,280 But unlike the historic M.M.U., it's the pilot who moves, 523 00:30:00,280 --> 00:30:04,120 or vectors, the engine's nozzles to give precise control. 524 00:30:07,220 --> 00:30:09,620 To our surprise, what started to bear fruit 525 00:30:09,620 --> 00:30:10,960 was not the idea of individually 526 00:30:10,960 --> 00:30:12,890 controlling the throttles of each engine. 527 00:30:12,890 --> 00:30:15,360 It was not vectoring them with adjustable nozzles. 528 00:30:15,360 --> 00:30:17,660 It was actually vectoring them using your arms. 529 00:30:17,670 --> 00:30:20,230 The geometry of those arm mounts is very, very specific, 530 00:30:20,240 --> 00:30:23,240 and suddenly, it unlocked a huge amount of stability and control. 531 00:30:23,240 --> 00:30:25,270 It feels entirely planted. 532 00:30:27,740 --> 00:30:30,510 The solution is to have three main points of thrust 533 00:30:30,510 --> 00:30:33,450 to form a stable tripod of air. 534 00:30:33,450 --> 00:30:36,280 All five engine nozzles are fixed. 535 00:30:36,280 --> 00:30:39,920 Those on the arms can be adjusted by simple movements, 536 00:30:39,920 --> 00:30:43,360 creating a stable three-point vector control system 537 00:30:43,360 --> 00:30:45,160 unique to the jet suit. 538 00:30:47,460 --> 00:30:50,100 So, this is the solution that we've found worked best, 539 00:30:50,100 --> 00:30:52,770 creating that three respective controls. 540 00:30:52,770 --> 00:30:55,340 So, one, two, and then three on the rear. 541 00:30:55,340 --> 00:30:56,800 And then between those three, 542 00:30:56,810 --> 00:30:59,740 you balance all of those thrust vector. 543 00:30:59,740 --> 00:31:03,640 For example, to lose altitude, you flare out the engines, 544 00:31:03,650 --> 00:31:05,880 which are operating at 100% all the time, 545 00:31:05,880 --> 00:31:07,950 and it will reduce your vertical thrust vector 546 00:31:07,950 --> 00:31:09,080 and you will descend. 547 00:31:09,080 --> 00:31:10,720 As you bring the arms in, 548 00:31:10,720 --> 00:31:12,550 you're increasing your vertical thrust vector, 549 00:31:12,550 --> 00:31:14,990 and you'll start to gain altitude. 550 00:31:14,990 --> 00:31:17,690 And then very small changes in those thrust vectors 551 00:31:17,690 --> 00:31:22,560 are enough to actually initiate roll or sliding side to side. 552 00:31:22,560 --> 00:31:24,260 And it's all to do with weight-shifting 553 00:31:24,270 --> 00:31:26,430 and thrust vector control. 554 00:31:28,940 --> 00:31:30,900 Maneuvering these cutting-edge jets 555 00:31:30,910 --> 00:31:34,340 is finessed for hours above the safety above water. 556 00:31:34,340 --> 00:31:37,110 Shadowing a nimble jetski proves the perfect way 557 00:31:37,110 --> 00:31:40,050 to fine-tune this skillful control. 558 00:31:40,050 --> 00:31:43,350 But with any flight, the stakes are high. 559 00:31:43,350 --> 00:31:46,620 It's critical that pilot Richard knows all five engines 560 00:31:46,620 --> 00:31:48,320 are operating smoothly. 561 00:31:52,430 --> 00:31:57,230 Engineer Alex Wilson is facing this communication challenge. 562 00:31:57,230 --> 00:31:59,000 When you're flying along at 30 miles an hour, 563 00:31:59,000 --> 00:32:01,330 10 feet above the ground, it's quite important you're able 564 00:32:01,340 --> 00:32:03,500 to monitor the amount of fuel that's left in your tank. 565 00:32:03,510 --> 00:32:04,940 It's quite a critical thing. 566 00:32:04,940 --> 00:32:05,970 You don't want to drop out of the sky 567 00:32:05,970 --> 00:32:08,370 because you've run out of fuel. 568 00:32:08,380 --> 00:32:09,980 Alex and the team's solution 569 00:32:09,980 --> 00:32:12,780 wouldn't look out of place in a Sci-Fi movie. 570 00:32:15,520 --> 00:32:20,520 The jet suit employs the latest engine control unit engineering. 571 00:32:20,520 --> 00:32:22,760 State-of-the-art electrical systems monitor 572 00:32:22,760 --> 00:32:28,060 and control each engine to optimize efficiency. 573 00:32:28,060 --> 00:32:30,430 An ultra-lightweight carbon helmet and visor 574 00:32:30,430 --> 00:32:35,370 with built-in display are wirelessly linked to the suit, 575 00:32:35,370 --> 00:32:39,840 constantly updating the pilot with engine and fuel data. 576 00:32:39,840 --> 00:32:42,710 The control board is the brains of the whole system. 577 00:32:42,710 --> 00:32:45,140 That monitors all of the five engines' data 578 00:32:45,150 --> 00:32:47,380 so that you can package this into the most important 579 00:32:47,380 --> 00:32:50,150 vital systems information to send up to the heads-up display 580 00:32:50,150 --> 00:32:52,290 so Richard can monitor his temperature, 581 00:32:52,290 --> 00:32:54,820 his rpm, most importantly, his fuel systems 582 00:32:54,820 --> 00:32:57,590 so he knows how much fuel he's got left. 583 00:32:57,590 --> 00:32:59,260 So head-up display. 584 00:32:59,260 --> 00:33:00,993 All right, so this is a new one, where we've taken... 585 00:33:01,000 --> 00:33:02,700 Alex is continuously developing 586 00:33:02,700 --> 00:33:04,060 the electrical systems. 587 00:33:04,070 --> 00:33:05,730 Do you want to try it on? 588 00:33:05,730 --> 00:33:09,070 Yeah, I do. 589 00:33:09,070 --> 00:33:10,940 He's currently testing improvements 590
