FIELD: engines and pumps.
SUBSTANCE: invention relates to turbo compressor rotors with the rear bearing support arranged above the combustion chamber. The joint of the shaft with the deflector and turbine disk contains the turbine disk and deflector fitted on the turbine shaft shank splines. The turbine disk and deflector are fitted on the shaft splines via flexible elements with a mounting surfaces between them, the disk being enveloped by the deflector. The said joint splines are rectangular. The proposed invention allows increasing the engine reliability by maintaining the turbine disk and deflector alignment relative to the shaft under all operating conditions.
EFFECT: higher reliability.
