1,179,899. Compressor blade fixing. GENERAL ELECTRIC CO. Aug. 31, 1967 [Dec.2, 1966], No.39916/67. Heading F1T. An axial-flow compressor stator or rotor blade assembly comprises a support member having a circumferential row of aerofoil blades projecting from it and including axially spaced supporting rings having opposed surfaces of substantial annular depth respectively disposed at the leading and trailing edges of the blades, and a mounting foot associated with each blade, each foot being bonded to its associated blade and to the opposed ring surfaces. Fig. 2 shows a stator blade assembly for the fan of a turbo-fan engine, comprising blades 30 of laminated construction, preferably comprising epoxy resin reinforced by glass or other fibres, extending between a casing 28 and an inner ring 32 each formed of honeycombed sheet metal 36 sandwiched between skins 34. Mounting feet 40, Fig. 3, are bonded to each end of each blade 30 and bonded at end surfaces 50 to annular surfaces 38 of the casing 28 and inner ring 32, as by means of epoxy resin adhesive. The blade enters a slot 44 in each mounting foot, with notches 48 registering with ribs 46. The gaps between the blades may be filled by aluminium strips 54.
