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.
Claims11
An extended expander cycle system, comprising:
- a rocket engine having a plurality of channels;
- a plurality of fuel supplied one-wheel-turbopumps, each of said plurality of fuel supplied one-wheel-turbopumps comprising a fuel pump, a fuel turbine, a first fuel conduit, and a second fuel conduit,
- wherein a fuel is received by said fuel pumps via said first fuel conduit, pressurized through said fuel pumps of the fuel supplied one-wheel-turbopumps, transferred to said plurality of channels for heating via said second fuel conduit, transferred from said plurality of channels to said fuel turbines via said second fuel conduit, processed by said fuel turbines and transferred to said rocket engine via said first fuel conduit of said plurality of fuel supplied one-wheel-turbopumps;
- and
- a plurality of oxidizer supplied one-wheel-turbopumps each of said plurality of oxidizer supplied one-wheel-turbopumps comprising an oxidizer pump, an oxidizer turbine, a first oxidizer conduit, and a second oxidizer conduit,
- wherein an oxidizer is received by said oxidizer pumps via said first oxidizer conduit, processed through said oxidizer pumps of the oxidizer supplied one-wheel-turbopumps, transferred to said plurality of channels for heating via said second oxidizer conduit, transferred from said plurality of channels to said oxidizer turbines via said second oxidizer conduit, processed by said oxidizer turbines and transferred to said rocket engine via said first oxidizer conduit of said plurality of oxidizer supplied one-wheel-turbopumps;
- wherein utilization of said plurality of channels for both said fuel and said oxidizer provides adequate energy for fuel and oxidizer pressurization.
4 more elements
A method of operating an extended expander cycle system, comprising:
- processing a fuel through a pump side of a one-wheel-turbopump, heating said fuel through a plurality of channels coupled to a rocket engine, processing said fuel through a turbine side of said one-wheel-turbopump, and delivering a processed fuel to said rocket engine for combustion,
- processing an oxidizer through said pump side of said one-wheel-turbopump, heating said oxidizer through the plurality of channels coupled to the rocket engine, processing the oxidizer through said turbine side of said one-wheel-turbopump, and delivering a processed oxidizer to said rocket engine for combustion, wherein both fuel and oxidizer are heated in same said rocket engine.
