ABSTRACT:
Compression waves are formed by detonating a mixture of fuel and air confined within a chamber that has a constricted output opening. The mixture is ignited instantaneously throughout a peripheral region of the chamber opposite the output opening, and this region is shaped relative to the dimensions of the chamber and the output opening so that the burning of the mixture accelerates toward the output opening and inward from the peripheral region. This dynamically compresses and detonates the mixture to form a high pressure compression wave and direct it out of the output opening. The instantaneous ignition can be by plasma jets or flames injected into the ignition region from an ignition chamber adjacent to the detonation chamber. The device can directly transform the chemical energy of a fuel into a high pressure thrust directed against a relatively movable resistance to serve as a prime mover suitable for many tasks. It can drive a piston, plunger, or rotor vane; provide propulsive thrust; or direct a compression wave through open air.
