Title:
ROTARY-AIR-VALVE FIRING PATTERNS MAKING RESONANCE DETUNING
Document Type and Number:
Japanese Patent JP2010223221
Kind Code:
A
Abstract:
To provide an engine which tries to improve a method to fire PDC (pulse detonation combustion) such that any resonance (resonation) frequency is detuned.
The engine (100) includes a compressor stage (101), a plurality of pulse detonation combustors (103), and a rotary inlet valve structure (105) having a plurality of inlet ports (104) through which at least air flows to enter the plurality of pulse detonation combustors during operation of the engine.A turbine stage (111) is disposed downstream of the pulse detonation combustors. Further, the ratio of the pulse detonation combustors to the inlet ports is a non-integer.
