GAS TURBINE ENGINE COMPRESSOR MECHANIZATION CONTROL DEVICE Russian patent published in 2018 - IPC F04D27/00 

FIELD: engines and pumps.

SUBSTANCE: invention relates to the field of gas turbine engine building and can be used in GTE electronic and hydromechanical, and hydromechanical automatic control systems (ACS). Gas turbine engine (GTE) compressor mechanization control device contains the engine turbocharger (TC) speed sensors at the engine inlet, computing device for the TC given speed value calculating and calculating according to the given laws, depending on the guide vanes (GV) and the air bleed valves (ABV) specified positions given TC speed, GV and ABV actual position meter, GV and ABV actual positions comparing mechanism with the specified ones, former of the control action on the GV and ABV drives until the GV and ABV actual positions become equal to the specified ones. Computing device is made in the form of volumetric cam with the engine specified throttle characteristic recorded thereon. One of which inputs is connected to the fuel metering device in the engine combustion chamber, the second one is to the air pressure sensor at the engine inlet. Output is connected to the GV and ABV positions setting device. At that, the device further comprises GV and ABV positions adjusting device by the engine TC speed measured value.

EFFECT: positive effect of the invention is to simplification of the GTE compressor mechanization control mechanism, which leads to its cost-cutting and increase in reliability.
