Abstract:
A shaped charge engine, comprising:an inner housing; a dome-shaped outer housing joined to the inner housing to define a plurality of blast-forming chambers, each blast-forming chamber having at least one fuel injector to inject air-fuel mixtures, at least one igniter to ignite the air-fuel mixtures, a central opening between the inner and outer housing defining a primary convergence zone, wherein the inner housing is generally annular in shape and includes a substantially conical projection that, together with the outer housing, forms the primary convergence zone, such that each blast forming chamber is positioned to deliver exhaust products to collide substantially simultaneously with exhaust products delivered from an adjacent blast forming chamber; a secondary convergence zone located to receive substantially simultaneously the exhaust products delivered through the primary convergence zone of each blast-forming chamber, whereby the exhaust products from the blast-forming chambers travel through the primary convergence zone from generally opposite locations collide at the secondary convergence zone approximately at the center of the shaped charge engine to produce a moving charge of exhaust gas; and a turbine rotor mounted configured to receive the exhaust products to provide rotary torque.
