Abstract

1,061,327. Turbine and compressor blade mounting. DAIMLER-BENZ A.G. Sept. 28, 1965 [Oct. 2, 1964], No. 41170/65. Heading F1T. A guide blade ring for a turbine or compressor of a gas turbine engine comprises blades B which are inserted radially outwardly through slots in an outer annular shroud A. An inner annular shroud C is then placed into position and each blade is drawn back radially until an extension 21 enters a slot or a recess in the outer wall 22 of the shroud C. When the required clearance g has been set, each blade is then welded to the shroud A, the weld extending around the entire periphery of the blade profile. As shown, the weld may be of greater thickness at each end so as to completely fill the gaps e, f between the blade and the flanges 11, 12 of the shroud A. The outer end 14 of the blade is of shallow U-shape to conform to the cross-sectional shape of the shroud A. The blades act as spokes to centralize the shroud C, the clearance g allowing relative thermal expansion.
