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.
Il Boeing X-51A WaveRider è un velivolo sperimentale spinto con scramjet sviluppato in collaborazione tra Boeing, NASA, DARPA, USAF e Pratt & Whitney Rocketdyne per viaggiare a regime ipersonico. Il programma WaveRider è diretto dagli Air Force Research Labs.
14 ago 2012 · The aircraft remained in air for 200 seconds at a top speed of Mach 5. Fuelled by military fuel JP-7, the scramjet engine of X-51 is designed to run for five minutes (300s), while the unmanned experimental supersonic aircraft X-43 is fuelled by hydrogen and runs for just 100s.
The X-51A program is a technology demonstrator and was not designed to be a prototype for weapon system. It was designed to pave the way to future hypersonic weapons, hypersonic intelligence, surveillance and reconnaissance, and future access to space.
3 giu 2010 · The X-51A successfully made the longest supersonic combustion ramjet-powered hypersonic flight to date off the southern California coast on May 26. It was powered by a SJX61-2 that was first validated in a NASA wind tunnel. The air-breathing scramjet engine, built by Pratt & Whitney Rocketdyne, burned for more than 200 seconds to accelerate the ...
25 apr 2016 · The X-51 is hauled into the air by the host ship (B-52) and then air-launched. The X-51 initially utilizes the power of a modified Lockheed Martin MGM-140 ATacMS (Army Tactical Missile System) solid rocket booster to help clear the host ship and reach initial speeds (approximately Mach 4.5).
26 feb 2010 · The X-51 is expected to fly about 900 kilometers under jet power in about five minutes, 30 times longer in duration than the X-43A flights. Boeing has built four X-51 aircraft for the...
