METHOD OF CONTROLLING FUEL FEED IN GAS TURBINE ENGINE COMBUSTION CHAMBER Russian patent published in 2017 - IPC F02C9/26 

FIELD: engines and pumps.

SUBSTANCE: specifying the required start time depending on temperature and air pressure at the inlet to the engine, additionally measuring the current time from the beginning of the run. The magnitude of the acceleration of the rotor on the mode of small gas required to implement the specified start time, continuously determine the startup process before reaching the small gas mode according to the following formula: (dn/dt)_start=(n_start-n_cur)/(t_start-t_cur) where n_start - rotor speed at a small strip; n_cur - current rotor speed; t_start - required startup time; t_cur - current time from the beginning of the run.

EFFECT: improvement of reliability of gas turbine engine on launch modes through the formation required to accelerate the rotor, which is refined continuously during startup until the preset mode.
