FIELD: engines and pumps.
SUBSTANCE: low-pressure turbine comprises vanned discs engaged with turbine shaft via bevelled claw. Vanned discs and bevelled claw comprise circular flanges with ledges composed of alternating solid and hollow parts at inner and outer periphery, respectively. Solid parts have passages for fasteners. Every solid part is engaged with periphery of the disc or bevelled claw by asymmetric concaved recesses. Other inventions of the set relates to low-pressure turbine disc and bevelled claw and gas turbine engine with such turbine.
EFFECT: longer life of disc flanges and bevelled claw.
