Research on the Torque and Starting Characteristics of a Turbopump Turbine [PDF]
Journal of the Korean Society of Propulsion Engineers, 2013 Torque characteristics of a turbopump turbine was analyzed using the turbine performance test result. Specific torque of the subject turbine could be expressed as a linear function of corrected rotor speed at a fixed pressure ratio and it has been confirmed by the test result.
