FIELD: aviation.SUBSTANCE: invention relates to aircraft fuel systems designs. Twin-engine rotary-winged aircraft is equipped with a plant for fuel supply of engines (2, 3, 4) of aircraft motor group (1). Two main engines (2, 3) are made with the ability of starting at least one rotor (5) of the aircraft in flight independently. Auxiliary engine (4) is able to start auxiliary devices (6), is mechanically connected with rotor (5) but not able to start it in flight independently. Auxiliary engine (4) is supplied with fuel by auxiliary pumps (33, 32) taking fuel from the main tanks (11, 12). Main engines (2, 3) are respectively supplied with fuel from the said main tanks (11, 12).EFFECT: ability of embedding the fuel supply assembly designed for the auxiliary engine into the general fuel supply system of the motor group.8 cl, 2 dwg |
