Abstract
857,800. Axial-flow compressors. GENERAL ELECTRIC CO. April 21, 1958 [April 29, 1957], No. 12546/58. Class 110 (1). A compressor comprises adjustable stator vanes 14 having shafts 24 which extend through openings in the casing 12 and annular support rings 37, surrounding the casing. Actuator rings 44 for adjusting the vanes are rotatably mounted on the support rings. The shafts 24 are mounted in sleeves 32 engaging seats on the casing. The rings 44 are supported on rollers 42 mounted in grooves 26 in the support rings. Arms 52 secured to the shafts 24 carry pins 50 engaging tapered cam slots 48 in the rings 44. The rings 44 are moved circumferentially around the casings to adjust the stator vanes by a piston-rod 106 actuating a master bellcrank 91 coupled to the rings 44 by a link 88 and further bell-cranks 86. The piston may be responsive to the speed, inlet temperature or discharge pressure of the compressor, or in the case of the compressor of a gas-turbine engine, to the engine control lever position. By selection of the lengths of the arms 52 and of the distances between the pivot points 77, 82 of the bell-cranks 86 for each stage, the angular vane adjustment for each stage may be the same despite differing space requirements between each stage. Alternatively the blade adjustment at each stage may be different by making the distance between the pivots 77, 82 different at each stage.
