Abstract

1,069,377. Compressor blade fixing. ROLLS-ROYCE Ltd. Feb.23, 1966, No.7875/66. Heading F1T. The compressor stator blades 21 are retained in the casing 15 of a gas turbine engine by projections 19 from the shroud platform 20 of each blade engaging in annular grooves 18 in rings 16 secured to the casing. Circumferential movement of the blades 21 is prevented by a locking plate 24 engaging an axial groove 23 in a blade platform 20 and grooves (22), Fig. 3 (not shown), in rings 16. The plate 24 substantially wholly blanks off the annular channel 17 between rings 16 to prevent the circumferential circulation of air therein. Since adjacent platforms 20 abut, only one plate 24 is necessary for the complete blade ring, but eight to ten, or one plate for each platform may be used. In an unstepped compressor casing the rings 16 are extended axially at their peripheries so as to abut together each locking plate 24 being further supported by a groove in the extensions. The mounting construction is applicable also to compressor rotor blades.
