One wheel turbopump

Abstract

An extended expander cycle system comprising a rocket engine having a plurality of channels; a plurality of fuel supplied one-wheel-turbopumps; a plurality of oxidizer supplied one-wheel-turbopumps; wherein utilization of the plurality of channels for both fuel and oxidizer and utilization of plurality of fuel and oxidizer supplied one-wheel-turbopumps provides adequate energy for fuel and oxidizer pressurization.

1 . A one-wheel-turbopump comprising:
 a housing;   a wheel rotatably mounted within said housing;   a pump structurally coupled to said wheel;   a turbine structurally coupled to said wheel;   a seal separating said turbine from said pump;   a first conduit coupled to said housing serving as a pump inlet and a turbine outlet; and,   a second conduit coupled to said housing serving as a pump outlet and a turbine inlet.   
     
     
         2 . The one-wheel-turbopump of  claim 1  further comprising securing means coupled to said housing adapted to secure a plurality of one-wheel-turbopumps together. 
     
     
         3 . The one-wheel-turbopump of  claim 1 , wherein said pump is a radial pump, a centrifugal pump or an axial pump. 
     
     
         4 . The one-wheel-turbopump of  claim 1 , wherein said pump is both a centrifugal pump and an axial pump. 
     
     
         5 . The one-wheel-turbopump of  claim 1 , wherein said turbine is a radial turbine, an impulse turbine or a reaction turbine. 
     
     
         6 . The one-wheel-turbopump of  claim 1 , wherein said turbine is both an impulse turbine and a reaction turbine. 
     
     
         7 . The one-wheel-turbopump of  claim 1  wherein the one-wheel-turbopump is stackable. 
     
     
         8 . The one-wheel-turbopump of  claim 1  wherein said one-wheel-turbopump is 3-D printed.
