Abstract

1,211,534. Axial-flow compressors; blade fixing. ROLLS-ROYCE Ltd. Nov. 6, 1967 [Nov.12, 1966], No. 50817/66. Headings F1C and F1T. In an air compressor for a by-pass gas turbine engine, stator blades 15 are secured at their radially inner ends to the compressor casing by members 17 the upstream parts of which form shrouds of the blades and the remaining parts thereof forming flexible extensions to accommodate relative radial displacement due to differential expansion between the blades and casing. The flexible extensions form a part of the flow passage through the compressor. One, two or more blades may be connected to each member, the blades being brazed to the members. Casing portions 11, 12 and vane structure 13 are cast as a single unit from aluminium alloy, and the blades are of titanium.
