Abstract

1470322 Cooling turbine vanes GENERAL ELECTRIC CO 22 March 1974 [28 March 1973] 12827/74 Heading FIT Cooling of turbine or compressor rotor vanes 10 is effected by providing one or more convoluted cooling passages 13, 14 in the vane aerofoil portion 12, and passing a cooling liquid therethrough from the root 18 to an annular manifold 16 having a discharge nozzle 17 for the cooling'liquid, each convolution of each cooling passage extending in a generally chordwise direction over the major part of its length. The passages may be of square cross-section, with the liquid not completely filling each passage. One or more passages may extend spirally around the aerofoil section, or separate passages be formed on the pressure and suction sides. Convoluted cooling passages 23, 24 may be provided on the platform 20 to connect cooling passages, e.g. 13, to continually supplied reservoirs (21), (22), Fig. 2 (not shown), in the rotor disc rim. The blade may be made by investment casting with leachable ceramic bodies to form passages in the platform and root. Practical examples are given for the maximum permissible radial separation between successive convolutions in a single cooling channel.
