Abstract

758,669. Axial-flow compressor stator casings. ROLLS-ROYCE, Ltd. Oct. 22, 1954 [Nov. 6, 1953], No. 30854/53. Classes 110(1) and 110(3) The stator casing of an axial-flow compressor comprises two (or more) part - circular sections 10, each having internal reinforcing webs 12. The stator blades 21 have root portions 22 each formed with axial projections 23 which engage in corresponding grooves 20 formed in the radially-inwardly-projecting flanges 18 of the ring part 16. Each ring part 16 is also formed with axial projections 17 which are engaged in corresponding grooves 15 in the sides of the reinforcing webs 12. The flanges 18 of each ring part 16 are also formed with axially-projecting flanges 24, the flanges of adjacent ring parts abutting at the working temperature of the machine so that the reinforcing webs 12 are protected from hot working fluid. The parts are located circumferentially by means of washers 25 accommodated in recesses 26 in the abutment flanges of the casing halves, the washers overlapping the ends of the ring halves and the roots 22 of the end blades 21. The casing is made from light alloy such as magnesium-base alloy, and the blade carrying rings 16 are made from an alloy having good hot strength properties. Specification 621,544 is referred to.
