It could move at extremely high speeds without generating a sonic boom. It would appear at one location, then disappear, then re-appear at another location. Using that, an aircraft could move from one position in the sky to another without traversing the intervening space.
The other possibility, that of non-local motion, has been left unexplored. Remember those two terms in the non-local form of gamma? We are using only one of them for propulsion-the spatial velocity one that depends on Newtonian mechanics. “Example: there are two kinds of position and two kinds of velocity. More advanced schemes bypass the sonic boom problem altogether: The air behind the shock is very low in density and this reduces the heat transfer effects.” The electric energy drives the air radially away from the craft and transforms the traditional conical shock wave into a weaker parabolic one. Such a vehicle might be “blunt bodied, lens-shaped or saucer-shaped” and would fly blunt face forward (like an Apollo heat shield). The ultimate goal is to build earth-to-orbit vehicles that reduce transportation costs by a factor of 100 to 1000. vehicles so designed could travel at Mach 25 (orbital velocity) but be subject to Mach 3 conditions in the region behind the shock wave. See “Mitigation/Elimination of Sonic Shock Waves”, : “. (Just don’t ask for a window seat.)īetter methods of eliminating sonic booms have been known for decades. It’s powered by turbofan engines, and has vertical fins on the rear to direct sound up and away from the ground. Rather than a tube with wings attached, this design uses a unified body and wings built together. The image above shows what a hybrid wing-body aircraft might look like. It’s hoped that new designs will avoid the sonic booms that cause so much disturbance, and instead produce more of a soft thump, or supersonic ‘heartbeat.’ Another illustration of what a quiet supersonic aircraft might look like. NASA thinks new aircraft designs can prevent this, and it starts with abandoning the ‘tube and wings’ model that current passenger aircraft design adheres to. This shockwave can travel up to 40 kilometres (25 miles), and can even break windows. When an aircraft passes the speed of sound, a shockwave is created in the air it passes through. The problem with supersonic flight-and the reason it’s banned- is the uber-loud boom that it creates. And if all goes according to plan, the first test-model could be flying as soon as 2020. If NASA’s 2017 budget is approved, the agency will re-start their X-Plane program, the same program which was responsible for the first supersonic flight almost 70 years ago. NASA has plans to develop new supersonic passenger aircraft that are not only quieter, but also greener and less expensive to operate.
