摘要
FIELD: machine building.;SUBSTANCE: invention relates to multi-engine helicopter power plant structure comprising gas turbine engines connected with power transmission reduction gear, differing by that it comprises at least one hybrid gas turbine engine (20), which is capable of operating in at least one standby mode during a steady-state flight at cruise speed of the helicopter; at least two control circuits (30; 40) of each hybrid gas turbine engine (20); wherein each circuit (30; 40) comprises electric machine (31; 41) connected to hybrid gas turbine engine (20) and adapted to bring its gas generator into rotation, and at least one power supply source (33, 43) of said electric machines (31; 41); wherein each re-actuation circuit (30, 40) is designed so that said gas turbine engine (20) can be switched over into at least one operating mode from plurality of preset modes.;EFFECT: allows to achieve very good readiness of re-actuation system.;9 cl, 7 dwg
