CONTROL METHOD OF JET TURBINE DOUBLE-FLOW ENGINE WITH AFTERBURNER Russian patent published in 2012 - IPC F02C9/00 

FIELD: machine building.

SUBSTANCE: control of jet turbine double-flow engine with afterburner in augmented modes consists in the following: as measured values there used is fuel consumption (G_{F mcc}) characterising the fuel consumption to the main combustion chamber (MCC), rotation frequency (n_r) characterising the rotation frequency of low pressure shaft, pressure (p_c*) characterising total air pressure after compressor; as control value there used is temperature (t_in*) characterising total inlet air temperature of engine and angle (α_tl) characterising the position of throttle lever (TL). In order to influence the actuating element determining the fuel supply to the afterburner, fuel consumption G_ta supplied to afterburner in augmented conditions is used as the value characterising the control signal, and it is determined in compliance with the programme as per the law (G_{F mcc} + G_ta) / (P_c*n_r) = f(T_in ^*, α_tl).

EFFECT: invention allows supporting the required thrust in augmented conditions at deterioration of characteristics of the engine components with operating time.
