Pressure, Ion Probe, and Flow-Visualization Measurements in Inside-Injector Rotating Detonation Engines

In this proposed study we investigated the more general detonation structure by using the Inside-injector Rotating Detonation Engines.Using a hypersonic-propagation detonation wave, engines can have higher thermal efficiency cycle and specific thrust than conventional jet and rocket engines. Particularly, a rotating detonation engine is now studied in the world. Since it has a simple double-cylinder structure with continuous detonation propagation, in which the detonation initiation is needed once only when the engine starts. Detailed visualization analysis experiments for the flow in a rotating detonation engine are needed immediately.
