Abstract:
A centrifugal direct injection engine comprising:a) an open-ended compartment having a combustion chamber at a closed end thereof, an exhaust nozzle at its open end and a narrow portion defining a throat being disposed between said combustion chamber and said exhaust nozzle;b) a propellant injection manifold rotatably mounted within said combustion chamber, said propellant injection manifold configured for rapid rotation within said combustion chamber;c) said propellant injection manifold having a plurality of nozzles;d) means for introducing a fuel and an oxidizer into said combustion chamber through said propellant injection manifold and said nozzles in said propellant injection manifold, the fuel and oxidizer mixing in said combustion chamber; ande) said propellant injection manifold being formed with a plurality of heat exchange channels for heating the oxidizer introduced through said propellant injection manifold and said nozzles into said combustion chamber;f) means for igniting the fuel and oxidizer mixture within said combustion chamber;g) at least a portion of said nozzles positioned to cause and sustain rotation of said propellant injection manifold within said combustion chamber after initial ignition of the fuel, whereby combustion is said combustion chamber is self-sustaining.
