| Abstract: | Taking the certain turboshaft engine for example, the variation of guide vanes angle with the eccentricity and deformation of joint ring was calculated and analyzed. The experimental verification of the compressor surge margin was accomplished. This research provides data support for case-based turboshaft engine troubleshooting. It can provide reference for the improvement development of the certain turboshaft engine. |
