Performance analysis for hydraulic retarder components of aero-engine

Aiming at the practical problems in the development and production of a hydraulic retarder of aero-engine,using reverse design and analyzing the structural principle of the hydraulic retarder and the corresponding test parameter requirements,a simplified model was established.A conclusion consisting with the actual engineering was obtained by combining the theoretical calculation,comparative test,AMES?im simulation and other means.The results show that on the basis of reliability level of the product,the orig?inal technical index was not reasonable,and the modified technical index can solve the difference between design index and engineering practice.The research results can provide a basis for the design and improve?ment of the leakage test of the hydraulic retarder components of the aero-engine,and also provide a refer?ence for the design,improvement and engineering troubleshooting of the components of the same structure.
