FIELD: internal combustion engines.
SUBSTANCE: object of invention is structure of power plant of multi-engine helicopter, which contains gas turbine engines (5, 6), characterized by that it includes the following: at least one hybrid gas turbine engine (5) configured to operate in at least one standby mode during an established flight of the helicopter, wherein other gas turbine engines (6) operate independently during said settled flight; air turbine (30) mechanically connected to gas generator (17) of hybrid gas turbine engine (5) and configured to actuate said gas generator (17); means of extracting air under pressure from gas turbine engine (27) of turbine engine (6) and pipeline (31) for delivery of said bleed air to said air turbine (30).
EFFECT: invention discloses a method of amplifying a gas turbine engine in standby mode of a multi-engine helicopter and a structure of a helicopter power plant, comprising at least one gas turbine engine, which can be in standby mode.
