COMBINED CLUTCHES KIT Russian patent published in 2023 - IPC F16D47/02 F16D13/42 B64C27/14 

FIELD: aircraft engineering.

SUBSTANCE: structures of helicopter transmissions. Set of combined clutches consists of a dry-type disc clutch with a steering rod passed through the hollow shaft of the engine gearbox, a compensating clutch with claws fixed on flanges with elastic elements put on them, and a freewheel clutch. The clutch is made with the possibility of kinematic interaction with the release bearing located outside the clutch. The rod provides constant compression of the clutch disc pack after the engine is started and warmed up. The compensation clutch is two-way and has the ability to compensate for both angular and translational transverse displacements of the engine.

EFFECT: engine movement compensation is achieved.
