PILOTLESS AIRCRAFT (VERSIONS) Russian patent published in 2017 - IPC G05D1/04 B64D35/08 

FIELD: aviation.

SUBSTANCE: in first version of the pilotless aircraft has two engines running on one propeller, shafts of which are connected by gears or controlled socket, or who work at a common gearbox with two pinions and connected with reducer by overspeed or clutch couplings. The power of the engine close to the propeller is 170-230% of the power of the second engine. In the second version, a pilotless aircraft has two engines working on a propeller through a gear unit in which the torque of a more powerful engine is transmitted directly, and the torque of a less powerful engine is transmitted via a downshift. Both engines are connected to the gear unit by overspeed or clutch couplings.
