ABSTRACT:
A regenerative liquid propellant engine system includes a body having opposed ends. A combustion chamber is disposed in the body. A reservoir of liquid propellant is also disposed in the body. A regenerative piston is slidably disposed in the body for delivering the liquid propellant to the combustion chamber. When combustion occurs in the combustion chamber the piston is driven into the liquid propellant reservoir and the liquid propellant is injected into the combustion chamber to produce combustion products. A storage tank stores a quantity of liquid propellant and a pump delivers the liquid propellant from the storage tank to the liquid propellant reservoir. The regenerative piston produces the necessary pumping pressure to operate the pump, thus, the mechanical complexity and inefficiencies of other pumping techniques is avoided.
