At hypersonic speeds
to spark combustion is the major challenge.
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.
Ultimately, a better understanding of the transition to turbulence at hypersonic speeds
will allow designers to build lighter, faster, more efficient craft capable of traveling at even higher speeds of Mach 15 or more.
During the experiment the scramjet climbed to about 100,000 feet in altitude aboard a sounding rocket, accelerated from Mach 6 to Mach 8, and operated about 12 seconds - a big accomplishment for flight at hypersonic speeds
The test facilities simulate flight from subsonic to hypersonic speeds
at altitudes from sea level to space.
NASA researchers are working to develop a new kind of lightweight inflatable spacecraft outer shell to slow and protect vehicles as they blaze through the atmosphere at hypersonic speeds
With 120-millimeter slugs flying at hypersonic speeds
, the time to kill or be killed is measured in seconds.
are described as falling between the range of Mach 5 and Mach 10, or 3,840 miles per hour and 7,680 miles per hour.
July 17, 2012 /PRNewswire-USNewswire/ -- NASA Space Technology Program researchers will launch and deploy a large inflatable heat shield aboard a rocket traveling at hypersonic speeds
this weekend during a technology demonstration test from the agency's Wallops Flight Facility on Wallops Island, Va.
It would use the same combination of buoyancy and electric propulsion to steadily accelerate over several days to hypersonic speeds
that would allow them to reach orbit.
Huge blobs of the material, held together by magnetic forces, streak into space at hypersonic speeds
The Pratt & Whitney Rocketdyne scramjet engine is the world's first air breathing hydrocarbon-fueled and -cooled propulsion system capable of powering vehicles at hypersonic speeds
