Abstract
A rim seal (70) for a rotor (48; 90) of a gas turbine engine (10) includes a seal portion (74) extending circumferentially across a rim cavity (68) of a rotor, the seal portion configured to seal the rim cavity and a first foot portion (76) extending radially inwardly from a first end (78) of the seal portion. A rotor assembly for a gas turbine engine includes a rotor disc (50; 94) and a plurality of rotor blades (52; 92) secured to the rotor disc defining a rim cavity between the rotor disc and a rim portion (66) of the plurality of rotor blades. A rim seal is located in the rim cavity and includes a seal portion extending circumferentially across the rim cavity, the seal portion configured to seal the rim cavity. The seal portion has an increasing radial thickness with increasing distance from a first end (78) of the rim seal and from a second end (78) opposite the first end.
