Abstract

1291302 Rotor blade assemblies DEFENCE, SECRETARY OF STATE FOR 19 April 1971 [14 March 1970] 12353/70 Heading FIT A bladed rotor comprises blades 11 having roots 13 engaging slots in rotor 12, the blades having platforms 15 between which and a portion of the rotor disposed radially inwardly of the slots, are sealing plate segments 20 overlapping at their ends to form an annular sealing plate, the segments being locked to the blades and rotor at their radially outer and inner peripheries. One of the locking elements comprises circumferential grooves 17 and 21 in which one or more locking wires is situated to extend around substantially the whole of the rotor's circumference. This locking element may be between the sealing plate segments and either the rotor or the blade platforms. The sealing plate may have an axially extending portion on which is mounted a labyrinth seal. The blades may have inter-locking shrouds.
