Abstract
A pulse detonation apparatus utilizes an inner housing which rotates relative to an outer housing. The inner housing has spherical inner seal surfaces that rotate with it. The outer housing has mating spherical seal surfaces that rotationally receive the inner seal surfaces. Ports extend through the inner seal surface and the outer seal surface. These ports register at least once per revolution. An inlet supplies a fuel mixture to the interior of the inner housing and each time the inner and outer housing ports align, the fuel mixture is transmitted into an annular detonation chamber where an igniter ignites the mixture to create a detonation wave. Circular seals surround the outer housing port to provide sealing against the high pressure, high temperature detonations. Purge air is admitted into the detonation chamber, a new fuel mixture is delivered to the detonation chamber, and the cycle is repeated.
