| Abstract: | The engine components, and whole engine test, flight projects and test purposes in the development process were analyzed based on the aeroengine relevant standards. The necessary of the limit enhancement test was proposed by classifying the tests. The methods,application principle and effectiveness of the limit enhancement test method for the accessory reliability were presented according to the failure mode and mechanism analysis. Aiming at high cycle failure, performance stability and durability, the reliability test condition and loading design requirements of engine were illustrated, and the suggestion of loading spectrum selection for the engine was proposed |
