Simulation of hypersonic speed (Mach 5) While the definition of hypersonic flow can be quite vague and is generally debatable (especially due to the absence of discontinuity between supersonic and hypersonic flows), a hypersonic flow may be characterized by certain physical phenomena that can no longer be analytically discounted as in supersonic flow.
Artist's concept of X-43A with scramjet attached to the underside NASA's B-52B launch aircraft takes off carrying the X-43A hypersonic research vehicle (March 27, 2004) The X-43A aircraft was a small unpiloted test vehicle measuring just over 3.7 m (12 ft) in length. [4]
The X-15's highest speed, 4,520 miles per hour (7,274 km/h; 2,021 m/s), [1] was achieved on 3 October 1967, [2] when William J. Knight flew at Mach 6.7 at an altitude of 102,100 feet (31,120 m), or 19.34 miles. This set the official world record for the highest speed ever recorded by a crewed, powered aircraft, which remains unbroken. [3] [4]
A Chinese aerospace firm has completed the first test flight of a passenger plane that it claims can fly at Mach 4 – more than twice the speed of Concorde.. Beijing-based Space Transportation ...
The first manufactured object to achieve hypersonic flight was the two-stage Bumper rocket, consisting of a WAC Corporal second stage set on top of a V-2 first stage. In February 1949, at White Sands, the rocket reached a speed of 8,290 km/h (5,150 mph), or about Mach 6.7. [1]
At Mach 0.65, u is 65% of the speed of sound (subsonic), and, at Mach 1.35, u is 35% faster than the speed of sound (supersonic). An F/A-18 Hornet creating a vapor cone at transonic speed just before reaching the speed of sound. The local speed of sound, and hence the Mach number, depends on the temperature of the surrounding gas.
Quarterhorse, the Air Force's next hypersonic aircraft, has taken an epic leap. The SR-71 Blackbird successor is a step closer to breaking the airspeed record.
Mach 7 or variation, may refer to: . Mach number for seven times the speed of sound . Hypersonic speed of 7 times the speed of sound; Mach-VII (Marvel Comics), comic book superhero alter-ego of Marvel Comics character Abner Jenkins
