Abstract
779,056. Turbine guide vane assembly. ROLLS-ROYCE, Ltd. Dec. 2, 1954 [Feb. 12, 1954], No. 4272/54. Class 110 (3). In a nozzle guide vane assembly such as a guide vane assembly of a gas turbine, the vanes are secured at each end in the adjacent parts of supporting structure and each vane has the securing connection at one end at least effected through flexible strip adapted to accommodate relative thermal expansion by bending. The guide vanes 12 which are disposed between rotor blading stages 10, 11 are mounted at their radially inner ends in apertures in rigid annular shrouds 13 and are welded thereto. The outer ends of the vanes pass through apertures in individual flexible strips 17 and are welded thereto. The strips extend beyond the leading and trailing edges of the vanes and are inclined in a direction parallel to the blade chords. The ends of the strips 17 are welded at their ends to annular members 18, 19, the member 18 having a radial flange by which it is bolted to the turbine stator casing 20, while the member 19 engages spigot-wise within the casing 20 and has axial freedom relative thereto. The vanes are hollow and are formed of sheet metal.
