It is extremely complicated and challenging to build an engine to power an aircraft at hypersonic speeds as its engines need to work by pushing the air back faster than the speed of travel.
Hyper-X consisted of the X-43A (a 12-foot-long unmanned research vehicle with a scramjet engine) and a rocket booster to push the X-43A to hypersonic speeds at an altitude of approximately 100,000 feet.
AFPN) -- For an aircraft to achieve hypersonic speeds, ranging from 6,000 to 15,000 mph (Mach 9 to Mach 22), and reach altitudes between 100,000 to 150,000 feet, it needs an airframe structure designed to survive intense heat and pressure.
They understand how this happens at slower speeds, but they still are grappling with which factors influence it at hypersonic speeds.
The mission marked the first time a scramjet engine had successfully powered a vehicle in flight at hypersonic speeds.
It also was expected to provide aerodynamic and aerothermodynamic data at hypersonic speeds.
In the decades-long quest to develop reusable aircraft that can reach hypersonic speeds Mach 5 and above engineers have grappled with two intertwined, seemingly intractable challenges: The top speed of traditional jet-turbine engines maxes out at roughly Mach 2.
For PSAAP, modeling the unstart phenomenon requires a clear understanding of the physics and then reproducing mathematically the immensely complex interactions that occur at hypersonic speeds, which explains why researchers from various backgrounds are working together on the project.
NASA officials on Monday were putting together a board to investigate Saturday's rocket failure, which destroyed the pilotless, 12-foot-long X-43A that the agency hoped to fly at hypersonic speeds over the Pacific Ocean.
The test facilities simulate flight from subsonic to hypersonic speeds at altitudes from sea level to space.
Instead of whizzing around in a circle, the electromagnetic field shoots the armature along the length of the rails, building up to hypersonic speeds.
