双转子涡喷发动机容畸变能力的试验研究

EXPERIMENTAL RESEARCH ON DISTORTION TOLERANCE CAPACITY OF A TWIN-SPOOL TURBOJET

本文介绍了某型双转子涡喷发动机在地面试车台上进行的进口流场压力畸变试验。重点分析了进口周向压力畸变和径向压力畸变对某型双转子涡喷发动机性能及可靠性的影响 ,为发动机 /进气道的匹配提供试验依据。

The inlet pressure distortion experiments of a twin-spood surbojet were completed at the ground test-ring.Under a variety of conditions of the inlet circumferential and radial pressure distortion,the distorting flow field,distorting index,critical distorting angle and sensitivity have been measured separetely by the steady and dynamic measuring systems.Meanwhile,the emphasis was placed on analysing the effect of inlet circumferential and radial pressure distortions on the performance and reliability of the twin-spool turbojet,the results of the analysis provide the experimental basis for matching between the engine and its intake.
