ABSTRACT:
A pulse detonation apparatus utilizes a rotatable core feed cylinder. The core feed cylinder is carried within a inner sidewall of a stationary annular detonation chamber. The core feed cylinder has ports in the sidewall that will register with ports in the inner sidewall of the annular detonation chamber at least once each revolution. A fuel valve means mounted to the outer sidewall of the annular detonation chamber supplies pulses of gaseous fuel. The oxygen content at the forward end of the detonation chamber is richer than toward the rearward end. The fuel is ignited to create a detonation wave. A purge gas flowing through the core feed cylinder enters the detonation cavity after the detonation wave has discharge for purging.
