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. [2]
The subsonic speed range is that range of speeds within which, all of the airflow over an aircraft is less than Mach 1. The critical Mach number (Mcrit) is lowest free stream Mach number at which airflow over any part of the aircraft first reaches Mach 1. So the subsonic speed range includes all speeds that are less than Mcrit.
The carrier aircraft first flew in April 2019, at the Mojave Air and Space Port, reaching 15,000 ft (4,600 m) and 190 mph (305 km/h) during a 2 hour 29 minute flight. [ 8 ] [ 9 ] Stratolaunch underwent a change of ownership and direction when Jean Floyd took over as CEO in 2019, reacquiring staff and growing to 87 employees by the beginning of ...
In Hermeus’s hypersonic design, a ramjet, which can only operate at high speeds as it uses this air to pressurize air and fuel in the combustion chamber, kicks in and carries the theoretical ...
Named after a legendary bird of prey, Stratolaunch’s Roc carrier plane has a wingspan of 385 feet. Massive air carrier tests launch off coast of Vandenberg. Are hypersonic flights next?
Stratolaunch was then reported to be aiming for a first flight within a few weeks and a first launch from the carrier in 2020. [24] The aircraft first flew on April 13, 2019, at the Mojave Air and Space Port, reaching 17,000 feet (5,200 m) and speed of 165 knots (306 km/h) in a 2 hours 29 minutes flight. [25]
The X-15 set speed and altitude records in the 1960s, crossing the edge of outer space and returning with valuable data used in aircraft and spacecraft design. 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 ...
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.
