MODULATION OF INLET MASS FLOW AND RESONANCE FOR A MULTI-TUBE PULSE DETONATION ENGINE SYSTEM USING PHASE SHIFTED OPERATION AND DETUNING

摘要

An engine contains a compressor stage, a plurality of pulse detonation combustors and a plurality of inlet valves, where the inlet valves direct a mass flow into the pulse detonation combustors. A control system controls at least one of a phase shift, firing frequency and a τopen/τcycle ratio of the pulse detonation combustors based on a mass flow and/or a resonance within the engine.
