Zusammenfassung: | A rotor disc of a gas turbine rotor assembly is provided. The rotor disc may support blades attached thereto. The rotor disc may have a plurality of fixing members defined therein through its peripheral surface and circumferentially spaced apart from one another. The fixing members may extend axially from a front end portion to a rear end portion of the disc. Profiled slots may be defined betweenpairs of adjacent ones of the fixing members and may be configured to receive complementary profiled blade root portions. A plurality of disc lips may project axially forward from a surrounding surface of the disc in the front end portion. A disc lip may be disposed at a tip portion of a fixing member, adjacent a leading edge of the disc to minimize air leakage at a disc/blade interface. A rotor assembly with such rotor disc and blades attached thereto is also provided.
