OIL SYSTEM OF TURBOJET ENGINES PLACED ON THE ROTOR BLADES OF A HELICOPTER Russian patent published in 2021 - IPC B64C27/18 B64D15/02 F02C7/06 

FIELD: aircraft engineering.

SUBSTANCE: invention relates to the field of aviation, in particular to the designs of jet drives of rotors. The oil system of turbojet engines placed on the rotor blades of a helicopter is designed to supply oil to engines while simultaneously performing the function of protecting the rotor blades from icing. A make-up oil tank (4) is mounted on the shaft (3) of the main rotor, which is connected to the oil system by a make-up pipeline (6). The oil system for each of the engines (1) placed on the corresponding blades (2) includes an oil supply pipeline (9), a hydraulic motor (10), on which the high oil pressure is lowered to operating pressures, and the torque from the hydraulic motor (10) is transmitted via a joint shaft (30) to a high-pressure pump (21), a pipeline (11), nozzles (13), crankcases (14, 15, 16) of the front, middle and rear supports. The oil cooler (23) is made in the form of a series of parallel channels evenly located in the nose of the blade (2) along its length, and provides oil cooling and protection of the blade (2) from icing.

EFFECT: reduction in the dimensions of the power plant is achieved.
