Continuous Detonation Combustor Operating on a Methane–Oxygen Mixture: Test Fires, Thrust Performance, and Thermal State

Aerospace
Test fires of a rotating detonation engine (RDE) annular combustor operating on a methane–oxygen mixture were conducted. Compared to the original RDE combustor previously tested, it was modified in terms of changing the layout of the water cooling system,
