摘要

FIELD: engines and pumps.SUBSTANCE: group of inventions describes test method of GTE for gas dynamic stability by means of the developed inlet aerodynamic device provided with a retractable intercepter and a graduated scale with fixation of boundary and intermediate positions in the air flow with various degree of aerodynamic shading and disturbance of the flow in full range of 0 to 100%. The developed versions of experimental evaluation of gas dynamic stability have been used during pilot, pilot-industrial and batch production and at the stage of operation of aircraft engines and improve evaluation reliability of gas dynamic stability, determination of the boundaries of the engine transition to surging, and safety margin of 2-5% of the critical value is set.EFFECT: use of the group of inventions opens new possibilities of conducting tests for gas dynamic stability both at the stage of production and adjustment of a test specimen of the engine, and at the stage of performance of proof test immediately at industrial production and operation of engines, including after the overhaul with the test effectiveness providing the best quality of the engine at all stages.15 cl, 2 dwg
