Design and verification of airworthiness compliance of equivalent endurance test cycle of turbofan engine
In order to optimize the endurance test cycle of the turbofan engine and reduce the number of triple red-line configuration modifications during the test,the equivalent design and compliance verification method of the endurance test cycle were studied.The damage characteristics of the original endurance test cycle and endurance test cycle at different stages were analyzed,and a design and verification method for the airworthiness compliance of the equivalent endurance test cycle based on the principle of equivalent damage was proposed to reduce the number of triple red-line configuration modifications.A simulated characteristic test piece was designed by taking the high-pressure turbine blade of a certain engine as an example.The proposed design and verification method for the airworthiness compliance of the equivalent endurance test cycle of a turbofan engine can be used as a reference for the optimization of the test cycle of the endurance airworthiness certification test of the whole engine,and the proposed design scheme of the simulated characteristic test piece can support the equivalent damage test of the simulated characteristic test piece.
