METHOD OF CONTROLLING GAS TURBINE ENGINE IN ACCELERATION AND THROTTLING DYNAMIC CONDITIONS Russian patent published in 2008 - IPC F02C9/28 

FIELD: engines and pumps.

SUBSTANCE: control over the gas turbine engine dynamic acceleration and throttling conditions is effected by measuring turbo-compressor rotor rpm n_tk and acceleration comparing with preset varying fuel feed flow rate into the combustion chamber depending upon the departure of current from preset Note here that the turbo-compressor inlet air temperature T_in* is measured, the turbo-compressor rotor rpm n_tcr reduced in compliance with the temperature T_in* by formula the magnitude of is defined from two preset relations and for acceleration and throttling conditions respectively. Now the engine actual thrust parameter is measured, compared with the preset magnitude to generate the acceleration signal I=1 or throttling signal I=0 to be sent to the magnitude generation unit. Fuel feed into the combustion chamber is varied to meet the aforesaid relations.

EFFECT: better quality of adjusting two-shaft two-section engine with valves bypassing air from low-pressure channel booster stages in dynamic conditions.
