The periodic combustion propulsion system comprises at least one periodic combustion chamber configured to contain periodic combustion and at least one supersonic exhaust nozzle coupled to the at least one periodic combustion chamber. The supersonic exhaust nozzle is configured with a variable exhaust expansion ratio.
Claims6
A periodic combustion propulsion system comprising:
- a periodic combustion chamber including a body having an exhaust port configured to release periodic combustion reactions as propulsive fluid;
- and
- a supersonic exhaust nozzle coupled to said periodic combustion chamber, said supersonic exhaust nozzle including an inlet coupled to a flexible side wall and an outlet coupled to said side wall distal from said inlet, said supersonic exhaust nozzle inlet being coupled to said periodic combustion chamber at a location proximate to said exhaust port, said flexible side wall and said outlet having variable dimensions correlated to periodic combustion in said periodic combustion chamber.
