Assignee: RTX CORPORATION
Field: Engines, pumps, turbines (Mechanical engineering)
Classification: CPC F  B | IPC B  F

Claim 0:
1. A powerplant, comprising:
a pre-burner;
a combustor fluidly coupled with and downstream of the pre-burner;
a second pre-burner fluidly coupled with and upstream of the combustor;
a power turbine fluidly coupled with and downstream of the combustor;
a mechanical load rotatably driven by the power turbine; and
a propellant system configured to direct fluid oxygen and fluid hydrogen to the pre-burner to provide an oxygen rich fuel mixture for combustion within the pre-burner, and the propellant system further configured to direct the fluid hydrogen to the combustor for combustion within the combustor with oxygen within combustion products received from the pre-burner; and
the propellant system further configured to direct the fluid oxygen and the fluid hydrogen to the second pre-burner to provide a second oxygen rich fuel mixture for combustion within the second pre-burner, and the propellant system further configured to direct the fluid hydrogen to the combustor for combustion within the combustor with oxygen within second combustion products received from the second pre-burner.
