A shaped charge engine includes an annular blast-forming chamber formed by joining inner and outer housings. A central through hole in the inner housing allows exhaust gases to exit. The outer housing comprises a generally round disk with an inner conical concave depression and through holes for the insertion of fuel and ignition. The blast chamber is preferably taper-conical in shape, wider at the base, and gradually decreasing in cross-sectional area as it rises to the apex. This construction forms a circular pinch point or throat toward the apex that produces a primary or first stage compression area. A secondary compression zone is created at the apex of the outer housing, just beyond the throat, producing hypersonic gases as generally opposing exhaust streams collide and are forced to exit the through hole in the inner housing. The shaped charge engine may be used in a variety of applications, including as a pulsed direct propulsion device, as a turbine driver, or in a wide array of tools and appliances.

1. A shaped charge engine, comprising:an inner housing; an outer housing joined to the inner housing to define a blast-forming chamber; a plurality of fuel injectors adapted to inject fuel into the chamber at generally diametrically opposite locations; and a central opening in the blast-forming chamber between the inner and outer housings defining a primary convergence zone; whereby exhaust gases traveling through the primary convergence zone from generally opposite locations collide at a secondary convergence zone substantially at the center of the shaped charge engine to produce a hypersonic exhaust; and, wherein the inner and outer housings are constructed of a non-circular, polygonal cross-sectional shape from a perspective orthogonal to the exhaust direction.
