METHOD OF CONTROLLING LOW-PRESSURE ROTOR RPM IN BYPASS GAS TURBINE ENGINE Russian patent published in 2012 - IPC F02C9/28

Abstract RU 2446300 C1

FIELD: engines and pumps.

SUBSTANCE: proposed method comprises controlling low-pressure rotor rpm, and comparing it with program magnitude to apply control signal to rpm adjustment actuator by influencing jet nozzle critical section. Note here that said low-pressure rotor program rpm is set to make the sum of low-pressure rotor rpm program magnitudes depending upon at temperature at engine inlet and engine control lever position.

EFFECT: higher efficiency of gas turbine engine operation.
