![]() “An airliner take-off acceleration is around 0.3g, and this is only for a small portion of the flight,” says Goodall. “If there’s some kind of accident, or sabotage, then the air will go out relatively quickly, and the pressure will drop under one thousandth of the atmospheric pressure, it could be very dangerous,” Jufer says. Just like with Hyperloop, many things could go wrong for Shifu’s supersonic train. But it’s widely used in Asia because of larger infrastructure and a reduction in cost as a result. Humans can easily tolerate the 0.5g (G-force) suggested for Hyperloop, but it probably won’t be acceptable to the travelling public in general.”Īlthough magnetic levitation was developed in Britain in the 1940s, it has failed to catch on because of the cost. “The proposed acceleration and deceleration levels are high. Shufu’s train is likely to “feature a transport system reducing air resistance, with a low vacuum environment and supersonic shape,” says Roger Goodall, a professor at Loughborough University who was involved in the original magnetic levitation projects in the UK, more than 70 years ago.

Magnetism because wheels would not be able to reach supersonic speeds because of friction. It can reach any point in the world within hours.What does one need to make a train surpass the speed of sound? Magnetic levitation and vacuum tubes – think Hyperloop – are key, says says Marcel Jufer, a professor at the Swiss Federal Institute of Technology in Lausanne (EPFL). ![]() The B-2 can travel 6,000 nautical miles without refueling and 10,000 nautical miles with only one refueling. The B-2 can reach a high subsonic speed and can also reach an altitude of more 50,000 feet. The B-2 is 69 feet long, 17 feet high and has a wingspan of 172 feet, half the length of a football field. Our employees also lead vehicle engineering, logistics and product support for the aircraft. From the extensive programmed depot maintenance that ranges from the complete restoration of the jet’s exterior surfaces to software engineering, testing and development. Northrop Grumman continues to upgrade and enhance the B-2’s capabilities, and service every B-2 aircraft. ![]() It has appeared in movies including “Independence Day,” “Armageddon,” “Iron Man 2,” “Cloverfield,” “Airplanes,” “Rampage” and, most recently, “Captain Marvel.” With an unmistakable silhouette and flying wing design, it’s easily one of the most recognized aircraft in the world. When Hollywood needs a “super bomber” to make a cameo and fight off a giant monster or an alien invasion, the red carpet is rolled out for the B-2. It then flew back to Missouri for another 30-hour flight for a total of more than 70 consecutive hours. The aircraft’s performance is even more impressive in that the B-2 made a quick pit stop for a 45-minute crew and service change with engines still running. In 2001, the Spirit of America and five other B-2s were the first to enter Afghan airspace for a record setting 44-hour mission. The B-2 holds the record for longest air combat mission in history. The B-2s flew less than 1 percent of the total missions, yet destroyed 33 percent of the targets during the first eight weeks of conflict.Ĥ – Beast Mode: Longest Aerial Combat Mission in History They attacked multiple targets, then flew directly back. Two B-2s flew more than 31 hours from Whiteman Air Force Base in Missouri to Kosovo. ![]() The B-2 saw its first operational use during Operation Allied Force. The B-2, one of the most survivable aircraft in the world, is the only aircraft to combine long-range, stealth and a heavy payload on a single platform. The B-2 went into enemy territory on Night One in support of Operation Allied Force (Serbia) Operation Enduring Freedom (Afghanistan) Operation Iraqi Freedom (Iraq) and twice in Libya in support of Operation Odyssey Dawn and Operation Odyssey Lightning. must go to war, the B-2 is there on the first night. Related manufacturing processes were also created. That list included tools, a software laboratory, composite materials, special test equipment, and 3-D modeling and computer systems. To bring the B-2 to life, Northrop Grumman had to invent all components from scratch.
