DETACHABLE GAS TURBINE ENGINE REACTIVATION UNIT, POWER PLANT ARCHITECTURE OF MULTIMOTOR HELICOPTER EQUIPPED WITH SUCH UNIT AND CORRESPONDING HELICOPTER Russian patent published in 2019 - IPC F02C7/277 F02C7/32 

FIELD: machine building.

SUBSTANCE: detachable unit for reactivation of a gas turbine engine of a helicopter, comprising a gas generator equipped with a drive shaft and configured to operate in standby mode during an established flight of a helicopter, includes a detachable housing containing an output shaft, and controlled means of rotation of the output shaft of the housing. Controlled means of rotation of housing output shaft, called gas turbine engine reactivation facilities, contain first and second reactivation devices, as well as mechanical means connecting housing output shaft with gas generator drive shaft with possibility of disconnection. First reactivation device is installed on the housing and contains a shaft called the first input shaft of the housing, which is mechanically connected to the output shaft of the housing, and controlled means of rotation of the first input shaft of the housing. Second reactivation device is installed on the housing and includes a shaft called the second input shaft of the housing, which is mechanically connected to the output shaft of the housing, and controlled means of rotation of the second input shaft of the housing. Other inventions of the group relate to the design of a power plant of a multi-engine helicopter containing the above detachable unit for reactivation of a gas-turbine engine, as well as to a helicopter containing the above structure of the power plant.

EFFECT: group of inventions makes it possible to provide the possibility of the gas turbine engine switching to the standby mode in case of necessity due to application of the detachable reactivation unit.
