FIELD: turbines.SUBSTANCE: invention is intended to improve characteristics at acceleration of gas turbine gas generator due to reduction of electric energy extraction, in particular, during transition phases, in order to preserve sufficient boundary of surge working curve. For this purpose, invention considers increased capacity of gas generator acceleration/deceleration by means of on-board electric mains voltage regulation on aircraft. In one version, after starting gas turbine onboard circuit voltage is adjusted by means of specified value of voltage (CT) controlled by steps of determining state of loading/unloading (E, E, E) of main source of electricity generation of on-board network. Determination of state is performed depending on demand in power takeoff (P) required for movement of aircraft.EFFECT: after that step, follows step of determining with selecting given voltage value (CT) between several levels (U, U, U) depending on loading/unloading state determination, and follows step of using selected preset value for control circuit of voltage supplied to onboard network.12 cl, 3 dwg |
