FIELD: transport.
SUBSTANCE: invention relates to aircraft engineering, particularly, to rotorcraft rotors. Propulsive and motion-transfer assembly (1), particularly, for rotorcraft comprises reduction gearmotor first and second assemblies (2) and (4) to drive at least one rotor of rotorcraft. Each of said reduction gearmotor first and second assemblies (2 and 4) incorporates a mechanical differential (6, 24) including first input shaft (8, 26), second input shaft (10, 28), output shaft (12, 30), and first and second motors (14, 32 and 16, 34) engaged with said first and second input shafts (8, 10, 26, 28). Output shaft (12, 30) of every assembly (2, 4) can spin jointly with rotor (23, 41) of rotorcraft.
EFFECT: decreased weight, simplified design, faultless operation.
