1. A two-stage pulse detonation system, comprising:
- at least one pre-combustor configured to burn a mixture of a hydrocarbon fuel and a gas;
at least one converging-diverging nozzle coupled to said at least one pre-combustor and configured to allow at least some of said burned mixture to pass through said at least one converging-diverging nozzle; and
at least one geometric resonator coupled to said at least one converging-diverging nozzle and configured to receive said at least some of said burned mixture and detonate at least a portion of said received burned mixture.

Abstract
A two-stage pulse detonation system includes a pre-combustor and a geometric resonator connected via a converging-diverging nozzle to the pre-combustor to create a high temperature and high pressure conditions in the resonator in order to create optimal conditions for detonation initiation. A mixture of a fuel and a gas is burned in the pre-combustor and is passed through the nozzle into the geometric resonator, where the burned mixture is detonated. The detonation propagates through the resonator exit nozzle thus generating thrust.
