Abstract

740,597. Turbine and compressor blades. GENERAL MOTORS CORPORATION. Nov. 7, 1953, No. 30875/53. Class 110(3) A gas turbine or compressor blade is hollow and has a tubular liner therein, the wall of the liner being corrugated and also perforated so that cooling fluid such as air. may pass from the liner to impinge on the inner surface of the blade wall. The blade comprises a root portion B formed of two parts 18, 19 and a vane portion A, comprising two wall portions 13, 14, bonded together at the leading and trailing edges, secured to the root portion. The liner C comprises two wall portions 23, 24 longitudinally corrugated and perforated at 29, bonded together at the leading and trailing edges, closed at the blade tip end 27 and open at the root end. A T- shaped plate 21 is secured between the two root portions by pins 37 engaging the corrugation 36 and the liner C is secured to the plate. The root portions 18, 19 are shaped to correspond with the corrugations of the liner so that coolant air introduced through ducts 32, 33 into the chamber 34 passes only through the liner. The ends of the chamber 34 are closed by pegs 35. The liner is stepped at 31 since the blade chord decreases towards the tip. The parts 14, 19 may alternatively be formed as a single forging or casting, and likewise the parts 13, 18.
