DARPA continues push toward high-speed aircraft with new Integrated Hypersonics program

DARPA continues push toward high-speed aircraft with new Integrated Hypersonics program: "DARPA has repeatedly indicated an interest in developing hypersonic aircraft and weapons systems which are capable of Mach-20 speeds and thus able to reach any region of the planet within an hour. To this end, the agency has announced its new Integrated Hypersonics (IH) program, which draws upon previous research and aims to create a hypersonic X-plane (HX) ready for testing by 2016."

The case in point is the Rotor dynamic wall from Climblock, which replaces the vertical wall with a rotating drum."
