A pulse detonation engine has a pulse ignition system, a plurality of detonation chambers (15), an oxygen source (33), and a fuel source (35). The oxygen source and the fuel source supply oxygen and fuel, respectively, to both the pulse ignition system and to the detonation chambers. The pulse ignition system creates detonation waves by igniting a first series of fuel mixtures inside a plurality of igniter tubes (39) equal to the number of detonation chambers (15). One detonation wave is delivered by each igniter tube into each detonation chamber for igniting a second series of fuel mixtures inside the detonation chambers. The detonation waves increase in magnitude as they travel through the detonation chambers before exiting the rearward ends of the detonation chambers. After detonation, the detonation engine is purged of residual gases by a ventilation system (81) and the process is repeated sequentially as described.

[ We claim:] [1.] A pulse detonation engine, comprising in combination:an oxygen source;a fuel source;a detonation chamber having an upstream end, an open downstream end, an oxygen port and a fuel port which are supplied with oxygen and fuel from the oxygen source and the fuel source, respectively, and a detonation wave port adjacent to the upstream end;a pulse detonation igniter tube having a downstream end communicating with the detonation wave port of the detonation chamber;an oxygen valve means for admitting oxygen from the oxygen source into the igniter tube;a fuel valve port located in the igniter tube downstream from the oxygen valve for communicating fuel from the fuel source to the igniter tube; andan igniter for detonating fuel and oxygen admitted into the igniter tube to create detonation waves, each of the detonation waves passing through the igniter tube, through the detonation wave port and into the detonation chamber for igniting fuel and oxygen admitted therein to enhance the magnitude of each of the detonation waves which discharge from the downstream end of the detonation chamber; andcheck valves located between the igniter tube and the detonation chamber for reducing a detonation port area, the check valves enhancing the strength of each of the detonation waves and preventing backlash waves from entering the igniter tube from the detonation chamber.
