Abstract

947,553. Gas turbine rotors. ROLLS-ROYCE Ltd. May 9, 1962, No. 17925/62. Headings FIG and FIT. A compressor or turbine rotor disc for a gas turbine engine has blades with cooling fluid conduits, means for supplying cooling fluid to one surface of the rotor disc, the surface being provided adjacent its outermost edge with the inlet ends of angularly spaced apart passages having outlet ends communicating with the cooling fluid conduits, each inlet end being disposed so that rotation of the disc causes the cooling fluid to be forced into the passages and through the fluid conduits. Blades 16 are mounted in grooves 18 of a rotor disc 15 and locked axially between plates 21, 22, plate 22 having flanges 23, 24 carrying an annular sheet metal member 30. Member 30 has inlet ends 32 of passages 33 having curved outlet ends communicating with apertures 36 in plate 22 and inlets 34 in the roots of blades 16. Each of the inlet ends 32 is disposed at an angle not exceeding 15 degrees to member 30 and each passage 33 has upper and lower surfaces diverging at 20 degrees. The inlets 34 communicate with internal conduits in the blades 16 and outlet 35 directed downstream. Rotation of the disc 15 thus causes cooling air to be forced through the conduits. In a modification, Figs. 5, 6 (not shown) member 30 is replaced by angularly-spaced cast metal members.
