Abstract

1460714 Turbine or compressor rotors ROLLS-ROYCE (1971) Ltd 24 May 1974 [26 June 1973] 30252/73 Heading FIT A turbine or compressor rotor for a gas turbine engine includes a longitudinally curved soft wire sealing member 28 loosely disposed in a radially outwardly tapering groove 27 between the adjacent faces of each pair of blade platforms or tip shrouds. Plates 30, 31 lock the blade roots and members 28 axially of the rotor. Members 28 also act as vibration dampers. A projection on one or both of the adjacent faces prevents member 28 from falling radially inwards.
