METHOD FOR DETERMINING EXTINCTION TURBOMACHINE COMBUSTION CHAMBER Russian patent published in 2016 - IPC F02C9/46 

FIELD: motors and pumps.

SUBSTANCE: invention relates to methods for determining the extinction of the combustion chamber of a gas turbine engine, preferably aviation applications. Method consists in that the measured pressure $$P_{IN}^{\ast }$$ and temperature $$T_{IN}^{\ast }$$ air entering the gas turbine engine, formed setpoint characterizing extinction chamber defined current value is compared with a predetermined additional measured fuel consumption G_t a combustion chamber formed minimum fuel consumption G_{t min} a combustion chamber formed functional dependence (G_t/P_k)_pr=f(n_{hp pr}), where the and if at the same time the current value fuel G_t greater than the calculated fuel consumption as defined by the functional dependence (G_t/P_k)_pr=f(n_hppr), G_t more G_{t min}, and in the absence of the engine stop signal forming an information signal "extinction of the combustion chamber", and outputs a control command to switch the ignition of the combustion chamber assembly.

EFFECT: invention improves the accuracy of determining the extinction of the combustion chamber, and improves reliability of the gas turbine engine.
