Abstract
A pulse detonation device is used to create high temperature high pressure pulses, such as for generating thrust for an aircraft or rocket. The device has a rotating cylinder located within a sleeve. A jacket is spaced outward from the sleeve. The seal and the sleeve are rotatable relative to each other. Each has ports which align with each other to communicate the annular passage with the annulus between the jacket and the sleeve. The jacket has at least one outer port. An outer valve in the exterior of the jacket opens and closes the outer port. A first portion of a fuel mixture, such as oxygen, is supplied to the inner passage within the cylinder, to flow into the annulus through the inner ports. The second ingredient of the fuel mixture, such as fuel, is supplied through the outer valves and outer ports to the annulus. An igniter in the annulus creates a detonation wave.
