FIELD: mechanical engineering. ^ SUBSTANCE: proposed stator of compressor of gas-turbine engine horizontally-split housing, turnable vanes of guide-vane assembly, control mechanism, lever secured on housing, and tie-rod. Control mechanism includes angular levers and rack, and tie-rod is adjustable in length. Turnable vanes of guide-vane assembly are installed in housing, are connected by levers with rings of drive and are connected through control mechanism to tie-rod hinge-connected to link of rack and short arm of additional lever. Long arm of additional lever is connected to hydraulic cylinder. Cross section of drive ring is H-section, and one of walls of drive rings is provided with slots to arranged ends of levers of turnable vanes. Sizes of slots are chosen to provide process clearance between each ring of drive and lever in process of assembling. ^ EFFECT: optimization of operation of compressor stator owing to improved reliability of operation at simultaneous increased accuracy of adjustment of turnable vanes of guide-vane assemblies in process of assembling and during operation. ^ 3 cl, 6 dwg |
