  • Oblique Wave Detonation Engine May Unlock Mach 17 Aircraft

    schwit1 shares a report from New Atlas: UCF researchers say they've trapped a sustained explosive detonation, fixed in place, for the first time, channeling its enormous power into thrust in a new oblique wave detonation engine that could propel an aircraft up to 17 times the speed of sound, potentially beating the scramjet as a hypersonic propulsion method. [...] Rotating detonation engines, in which the shockwaves from one detonation are tuned to trigger further detonations within a ring-shape...
