How a scramjet works

WebIn a ramjet, the combustion chamber - where the air is mixed with fuel and ignited - only works at subsonic speeds. So the intake slows the air down, releasing some of its energy as a shock wave, but this reduces fuel efficiency. The scramjet is an innovation on the ramjet in which the combustion chamber is specially designed to operate with ... Web20 de mai. de 2024 · That’s why scramjets, though conceived in the 1950s, still remain a work in progress. In the early 2000s, NASA’s X-43 used scramjets for about 10 seconds in flight. Since 2013, the United States Air Force X-51A Waverider has held the duration record with a 210-second burn that pushed the plane to Mach 5.
