Model of low-thrust pulse detonation device with valveless fuel feed

A model pulse detonation engine of low thrust is designed. A valveless fuel and oxidant feed was used to ¦ll a combustion chamber. The detonation was formed in the §ow of mixed fuel and oxidant. The in§uence of oxidant on the engine operation mode, the in§uence of ring obstacles and prechambers on de§agration-to-detonation transition (DDT), andthe in§uence offuel onengine outputparameterswereinvestigated. Air€hydrogen and air€hydrocarbonmixtures were used.
