PROPULSIVE AND MOTION-TRANSFER ASSEMBLY, PARTICULARLY, FOR ROTORCRAFT Russian patent published in 2015 - IPC B64C27/12 

FIELD: transport.

SUBSTANCE: invention relates to aircraft engineering, particularly, to rotorcraft rotors. Propulsive and motion-transfer unit (1) comprises hydrostatic transmission (2). The latter includes first hydraulic machine (18) to convert mechanical power into hydraulic power and first hydraulic machine (26) to convert hydraulic power into mechanical power. It includes also second hydrostatic transmission (8) including second hydraulic machine (62) to convert mechanical power into hydraulic power and second hydraulic machine (70) to convert hydraulic power into mechanical power. Each of said first and second hydrostatic transmissions (2, 8) includes high-pressure branch (24, 68) and low-pressure branch (30, 74) each communicating in every first and second hydrostatic transmissions (2, 8) to perform hydraulic communication of hydraulic machines. Said unit (1) comprises valves (108, 112) to communicate (106) low-pressure branch (30) of first hydrostatic transmission (2) and low-pressure branch (74) of second hydrostatic transmission (8) and to communicate (110) first hydrostatic transmission branch (24) with second transmission branch (68).

EFFECT: higher safety at failures.
