The precise Mach number at which a craft can be said to be flying at hypersonic speed varies, since individual physical changes in the airflow (like molecular dissociation and ionization) occur at different speeds; these effects collectively become important around Mach 5–10. The hypersonic regime can also be alternatively defined as speeds ...
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. [1]
It is powered by a solid-fuel rocket motor and is capable of achieving hypersonic speeds of at least Mach 5, though more specific details about its flight profile have not been disclosed. [3] According to Rick Loy, Senior Program Manager for the Missile and Fire Control division at Lockheed Martin, the Mako is “compatible with any aircraft ...
Nation: U.S.A. | Length: N/A | Weight: N/A | Range: 350+ miles | Speed: Mach 5+ The Hypersonic Air-breathing Weapon Concept, or HAWC, is a joint project between the U.S. Air Force and the Defense ...
The alliance says its speed has been put at Mach 8, or almost 9,900 kilometers per hour (6,138 mph). Hypersonic is defined as any speed above Mach 5 (3,836 mph).
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 ... go as fast as Mach 6 and “make the hypersonic ...
The North American X-15 is a hypersonic rocket-powered aircraft operated by the United States Air Force ... (6,294 km/h) (Mach 5.51) 21.2 mi (34.1 km) ... Mach Max speed
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 flight of over six minutes and reached speeds of over Mach 5 for 210 seconds on 1 May 2013 for the longest duration powered hypersonic flight.
