Turbopump exhaust.



A turbopump, mounted on the front of the engine, delivers the propellants in the desired quantities and at the proper pressures to the engine.


The turbopump contains a gas generator, a two-stage, axial-flow turbine, and two centrifugal pumps on a common shaft. Each pump supplies one of the propellants to the engine.


The monopropellant for driving the turbine is 90 percent hydrogen peroxide (H2O2). An electrohydraulic power servo system governs turbine speed to the selected power requirement.
