GAS TURBINE ENGINE AUTOMATIC CONTROL SYSTEM Russian patent published in 2008 - IPC F02C9/28 

FIELD: engines and pumps.

SUBSTANCE: invention relates to gas turbine engine automatic control systems (GTE ACS). The GTE ACS incorporates the following components connected in series, i.e. rotor rpm meter, the first comparator element and a minimum algebraic selector, a rotor rpm corrector channel and an adder, a differentiating corrector and a key, the key output being connected to the adder second input, a gas turbine engine, a gas temperature meter, the second comparator element, a comparator, a differentiator and a memory unit, the gas turbine engine second output being connected to the rotor rpm meter. The second comparator element output is connected to the algebraic minimum selector second input. The comparator second input is connected to the first comparator element out, the output of the former being connected to the key second input. The differentiating corrector output is connected to the memory unit second input, the said memory unit output being connected to the adder third input. The first comparator element second input is connected with the rotor rpm controller, the second comparator second output being connected to the gas temperature controller. The system incorporates additionally an electronic isodromic controller and static actuator. Note that the said isodromic controller input is connected to the algebraic minimum selector while its output is connected to the rotor rpm corrector input. The static actuator input is connected to the adder output, while its output is connected to the GTE input.

EFFECT: higher selecting control dynamic accuracy due to ruling out the overtemperature and temperature jumps.
