Abstract

1,123,586. Mounting turbine blades. LICENTIA PATENT-VERWALTUNGS G.m.b.H. Sept. 3, 1965 [Sept. 4, 1964], No. 37756/65. Heading F1T. An adjustable stator blade for an axial-flow gas turbine comprises two adjusting screws 21, 22 screwed into the blade root 18 and fitting snugly between the walls 25, 30 of an annular groove 17 which is formed by an admission casing 14 and a shroud ring 15. An annular flange 20 projects into an annular groove 19. Adjustment of the blade angle through a range of 6 degrees is effected by adjustment of the screws 21, 22, the shroud ring 15 being removed to provide access to the screws. At its other end, the blade is provided with a pivot formed by spherical segments 27 engaging an annular groove 28 provided with packing 33.
