FIELD: aircraft engineering; aircraft engines.
SUBSTANCE: proposed disk-to-rotor shaft connection unit contains shaft with splines made on its surface in place of disk mounting. Flange of disk is provided with mating splines. Splines of disk and shaft are screw-like, in form of multistart thread, with helix angle not less than 25°.
EFFECT: improved reliability of engine owing to provision of rigid connection of disk and shaft.
