Hypersonic flight. Hypersonic flight is flight through the atmosphere below altitudes of about 90 km (56 mi) at speeds greater than Mach 5, a speed where dissociation of air begins to become significant and high heat loads exist. Speeds over Mach 25 have been achieved below the thermosphere as of 2020. [citation needed]
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.
Hypersonic weapon. An Air-Launched Rapid Response Weapon (ARRW) carried by a B-52 bomber. Scramjet-powered hypersonic cruise missile. Comparison of Ballistic Missile and Hypersonic Glide Vehicle (C-HGB) Flight Trajectories for the LRHW Program. A hypersonic weapon is a weapon capable of travelling at hypersonic speed, defined as between 5 and ...
On August 21, 1961, a Douglas DC-8-43 (registration N9604Z) exceeded Mach 1 in a controlled dive during a test flight at Edwards Air Force Base. The crew were William Magruder (pilot), Paul Patten (copilot), Joseph Tomich (flight engineer), and Richard H. Edwards (flight test engineer). [38] This is the first supersonic flight by a civilian ...
The Hypersonic Air-breathing Weapon Concept (HAWC, pronounced "hawk") is a scramjet powered hypersonic air-launched cruise missile project at the U.S. Defense Advanced Research Projects Agency (DARPA), [1] that had a successful hypersonic flight announced in September 2021. [2][3] It is a kinetic energy weapon, without an explosive warhead. [4]
The Boeing X-51 Waverider is an unmanned research scramjet experimental aircraft for hypersonic flight at Mach 5 (3,300 mph; 5,300 km/h) and an altitude of 70,000 feet (21,000 m). The aircraft was designated X-51 in 2005. It completed its first powered hypersonic flight on 26 May 2010. After two unsuccessful test flights, the X-51 completed a ...
Chimera is a pre-cooled, full-range, air-breathing, turbine combined cycle (TBCC) hypersonic engine combining a pre-cooled turbine with a ramjet. At low speeds Chimera operates as a turbine, while at higher speeds the engine transitions to ramjet mode. The precooler helps bridge the gap between these modes increasing the performance of the turbine.
Hypersonic glide vehicle. Chinese DF-ZF hypersonic glide vehicle mounted on the DF-17 ballistic missile. A hypersonic glide vehicle (HGV) is a type of warhead for ballistic missiles that can maneuver and glide at hypersonic speed. It is used in conjunction with ballistic missiles to significantly change their trajectories after launch.
