CONTROL SYSTEM OF POSITION OF GUIDE VANES OF COMPRESSOR OF DOUBLE-FLOW GAS TURBINE ENGINE Russian patent published in 2011 - IPC F04D27/00 

FIELD: engines and pumps.

SUBSTANCE: control system of position of guide vanes of compressor of double-flow gas turbine engine includes drive of guide vanes of compressor; shaping unit of programme value of air compression degree in fan, the output of which is connected to the first input comparison element, the second output of which is connected to output of divider. System is equipped with shaping unit of corrected rotation frequency of low pressure rotor the inputs of which have the possibility of being connected to sensors of rotation frequency of low pressure rotor and engine inlet air temperature, and output - to input of shaping unit of programme value of air compression degree in the fan, which are in-series connected with shaping units of corrected rotation frequency of high pressure rotor, shaping units of restriction programme of position of guide vanes, logic restriction; inputs of shaping unit of corrected rotation frequency of high pressure rotor have the possibility of being connected to sensors of rotation frequency of high pressure rotor and air temperature at the engine input; at that, system is equipped with shaping unit of restriction programme of position of guide vanes of compressor the inlet of which is connected to drive of compressor guide vanes, and outlet is connected to inlet of logic restriction unit; inputs of divider have the possibility of being connected to air pressure sensors after and before fan; comparison element output is connected to isodromic governor the output of which is connected to input of pulse-width modulation unit, the output of which is connected to the first input of switch, to the second input of which the output of logic restriction unit is connected, and output of switch is connected to drive of guide vanes of compressor.

EFFECT: effective function of GTE owing to providing optimum operation of compressor in all GTE operating modes.
