ABSTRACT:
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.
