Abstract
751.127. Turbine and compressor blades. GENERAL MOTORS CORPORATION. March 5. 1954 [March 12, 1953], No. 6439/54. Class 110(3) A turbine or compressor blade comprises two parts 13, 14 which abut face-to-face, each part comprising a -portion of the aerofoil and a portion of the root, the parts being secured together by means of a dovetail joint which extends longitudinally of the blade. The concave blade part 13 is formed with a dovetail tongue piece 21 and the convex part 14 is formed with a dovetail groove 22. The abutting faces of the two parts are formed with grooves 23, 24 which upon assembly form a longitudinal passage 26 extending from the blade root to adjacent the blade tip, for the flow of cooling air. The tongue piece 21 is cut away to form transverse passages 34 which communicate with the passage 26. The abutting face of the convex blade part 14 may be recessed at 29 so as to constitute with the concave part 13 a narrow slit 31 through which cooling air may escape. The blade root is of the fir-tree type and axial movement of the blade in the rotor slot is prevented by means nf a pin passed
