Abstract
769,148. Turbine and compressor blade assemblies. GENERAL MOTORS CORPORATION. May 9, 1955, No. 13329/55. Class 110 (3). A compressor or turbine stator blade assem bly comprises inner and outer arcuate members of strip metal secured together, blades being inserted radially through slots in one of the members, each blade having a root in the form of a flat platform which is sandwiched between the two arcuate members to secure the blade against radial movement, and a shoulder which by interlocking engagement with a slot in one of the members, secures the blade against rotation. In a first embodiment the inner arcuate member 3 is of channel section as shown in Fig. 5, and has surfaces 8 and upstanding flanges 9, and is formed with apertures 10 of polygonal shape. A blade 12 having a platform 15 and a shouldered portion 17 is passed through each aperture 10, the shouldered portion 17 engaging the aperture 10 and being of corresponding shape prevents rotational movement of the blade. The outer arcuate member 4 which is formed with apertures 11 is then placed in position, tangs 16 on the blade roots passing through the apertures 11. The upstanding flanges 9 are finally crimped over the outer edges of the member 4. In a second embodiment (Fig. 7, not shown) both the inner and outer arcuate members 3 and 4 are of channel section and the corners of the tangs 16 on the blade roots are staked to the' outer arcuate member 4. In Fig. 9 the outer arcuate member 4 is received within the channel of the inner member 3 and is welded thereto at 30. In Figs. 10 and 11, the flanges of the inner arcuate member 3 are formed with castellations 24 which engage in notches 23 formed in the edges of the outer member 4, the parts being welded at 25, 28 after assembly. The blade roots are similar to those of the first embodiment. In a further embodiment, the end of the blade root projecting through the outer member is riveted over and the rivets of the plurality of blades form the only means by which the inner and outer members are connected together.
