FIELD: mechanical engineering; air industry.
SUBSTANCE: invention relates to design of fan support for aircraft and ground application gas-turbine engines. Proposed support contains rotor including disk, trunnion with fitted-in bearing inner race, contact ring, front and rear labyrinth bushings and mating sealing rings of stator. Disk trunnion is made cylindrical to place of connection with disk. Front and rear labyrinth bushings are made integral, and sealing rings of stator are made integral also. Solid labyrinth bushing is fixed on rotor trunnion by pins.
EFFECT: improved specific parameters of engine, reduced weight of support and increased its manufacturability.
