METHOD OF AVIATION GAS TURBINE ENGINE CONTROL AT TAKEOFF IN CASE OF FIRE Russian patent published in 2017 - IPC F02C9/26 

FIELD: engines and pumps.

SUBSTANCE: reception of the signal "V1. The speed of decision-making" is controlled, the parameter T_n/c characterizing the thermal condition in the engine nacelle is measured and compared with a predetermined value . In case of the simultaneous presence at takeoff of the signals "Fire in the nacelle" and "V1. The speed of decision-making", the current n_t is recorded for using as a set value for maintaining stable flow rate of fuel into the combustion chamber. In case of the signal "Fire in the nacelle," with simultaneous fulfillment of the condition, reducing fuel consumption to that appropriate to the mode of engine flight idle is carried out. Moreover, in case of maintaining these conditions for 1-3 seconds, the fuel supply into the combustion chamber is completely stopped. In the case of cancelling the signal "Fire in the nacelle", the engine work mode fixation is stopped.

EFFECT: invention allows to improve the flight safety on takeoff.
