In a study published earlier this month, People's Liberation Army researchers discussed a model that could help the military land its future hypersonic UAVs.
Their research looked at an"unpowered return guidance scheme" for unmanned aerial vehicles traveling at five times the speed of sound. At that speed, and from an altitude of 19 miles, the engine of the hypersonic UAV would need to be shut down 125 miles from the intended landing runway,According to the abstract by Dai et al.
Neither humans nor the fastest of computers would be able to intervene and provide course corrections at Mach 5, the newspaper said in its latest report into under-development, next-generation PLA technology. The solution, the researchers said, was to improve the software"to better predict possible landing scenarios."
To slow down the UAV, the military scientists would have it perform subtle S turns, but only within the stress limits allowed by the aircraft's wings or body, the study said.
that, by 2035, could ferry 10 passengers to anywhere on Earth within an hour. By the mid-2040s, the aircraft could be delivering 10,000 tons of cargo and 10,000 people to space—or moon—stations every year.that could manipulate the shock wave at the nose of a moving aircraft or missile to allow for faster and safer travel.
