This invention relates to a bladed rotor for a gas turbine engine which comprises a disc having blade carrying slots in its periphery. In order to seal the spaces between the blade platforms and the disc an annular array of sealing plates is provided. The plates are supported directly from the disc by a rivet, pin or the like which passes through the disc in between the blade carrying slots, in this way avoiding any additional loading on the blades themselves.

A bladed rotor for a gas turbine engine comprising a rotor disc having axially extending blade retention slots in its periphery, a plurality of rotor blades each having a root which engages with one said slot to support the blade and at least one annular assembly of sealing plates adapted to provide a seal between the blade platforms and the disc, a retaining member associated with each said plate, each said retaining member extending through the plate and through that portion of the periphery of the disc lying between said blade retention slots, said retaining member assuming loads of its respective plate and distributing such loads across the thickness of said disc thereby eliminating localized stress build-up in said disc from the respective one of said plates and also eliminating loads from the respective one of said plates on said blades, said retaining member restraining the respective plate against axial, radial and circumferential motion.
