摘要

To prove the validity and reliabilityrnof engine surge eliminating system ,surge test isrnconducted through disturbed board installed inrnnacelle inlet of flight bed. The test by installedrnthe board blockage ratio of 30%、40%、50% onrnthe ground and the board blockage ratio of 40%rnin the air were accomplished successfully .Thernresults and date of experiment were discussedrnand analyzed in this paper.
