Rocket engine assembly

A compact pulse rocket engine assembly comprising:

• an elongated substantially cylindrical housing containing an elongated axially extending combustion chamber;
• a nozzle means located within said housing in fluid communication with and adjacent to an end of said combustion chamber;
• a pair of axially extending charging chambers located within said housing adjacent an opposite end of said combustion chamber, one of said chambers for receiving a fuel and the other of said chambers for receiving an oxidizer, each of said charging chambers and said combustion chamber extending along axes parallel to one another;
• two valve means located within said housing, one of said valve means extending through one of said charging chambers to said combustion chamber and providing for the injection of a fuel into said combustion chamber and the other of said valve means extending through the other of said charging chambers to said combustion chamber and providing for the injection of an oxidizer into said combustion chamber, each of said valve means including (a) a hollow valve body slideably mounted within said housing, said valve body having a fluid passageway therein providing the sole means for fluid communication between one of said charging chambers and said combustion chamber, each of said valve bodies and passageways providing for impingement of fuel and oxidizer upon one another along the axis of said combustion chamber said valve body having an end adjacent said combustion chamber defining a differential area piston;
• (b) a valve stop located within said hollow body for controlling the flow of fluid from said charging cavity through said passageways in said hollow body to said combustion chamber and;
• (c) biasing means for resiliently urging said valve stop to a closed position for prohibiting fluid flow from said charging chamber through said valve body to said combustion chamber;
• actuation means for overcoming said biasing means and moving said valve stop to a position to permit fluid flow from said charging chamber through said passageways to said combustion chamber;
• linkage means interconnecting each of said valve means for ensuring that said valve bodies move in unison, said linkage means comprising a pin extending transverse to the axes of and interconnecting and linking the valve bodies of each of said valve means;
• means for introducing an oxidizer into one of said charging chambers, and;
• means for introducing a fuel into the other of said charging chambers.
