Abstract

1,033,759. Turbine blades. ROLLS-ROYCE Ltd. May 17, 1965, No. 20833/65. Heading F1T. A turbine blade has a main cooling air bore 11 extending from the root to the tip of the blade and communicating with further radially extending bores 14, 15 by way of slots 20 having a converging portion 26 and a portion 27 of constant width. Fins 23 in bore 14 adjacent leading edge 16 assist the cooling. Bore 15 communicates through a slot 25 with the blade external surface adjacent trailing edge 17. In a modification, Fig. 2 (not shown), slots 20 converge continuously from bore 11 to bores 14, 15 except at the radially inner and outer ends of the slots which have portions 21 of constant width. Fins 24 are also provided in bore 15.
