FIELD: control of gas- turbine engines. SUBSTANCE: pressure differential of air at flow regular and rotational speed of rotor are measured on engine equipped with flow regulator. Signal of preset differential at flow regulator is shaped in proportion to rotational speed of rotor and supply of cooling air is changed in proportion to deviation of measured differential from preset one. EFFECT: enhanced efficiency. 3 dwg
