Abstract: An analysis and research on propagative mechanism of detonation wave in combustionof blended gases is carried out. Meantime, a methed to determine velocity of detonation wave is putforward, and calculation of characteristic parameters of detonation wave preduced in blended gascombustion of liquid fuel (gasoline, kerosene) -air is made. All these are made in order to providetheoretical bases for design, analysis of working principle, priperty and cycle, and experimentalresearch of pulsed detonation engines.

Key words: Gas mixture;Detonation wave;Wave propagation;Pulsed detonation engine
