摘　　要：根据国产新材料在某型飞机上的应用情况,按照积木式试验层次规划了国产新材料装机应用疲劳考核验证试验,确定试验考核部位及考核内容;结合研发试验情况,确定了与进口材料性能相当或满足型号寿命设计要求的双重试验考核指标;基于规模最小和疲劳精准考核并重的原则,进行疲劳考核试验群优化设计,建立了一套可用于新材料在飞机型号应用的疲劳考核验证技术。根据试验研究结果,给出了国产新材料在某型飞机上的装机应用结论。According to the application of domestic new materials in the aircraft, the building block test plan is carried out, and the content of test evaluation is determined. According to the condition of research and development test, the double test evaluation index is determined, which is equal to the performance of imported materials or meets the life design requirements. Base on the principle of minimum scale and equal weight of precision assessment, the optimal design of test group is carried out. A set of fatigue test and verification technology which can be used for the application of new materials in aircraft model is established. According to the experimental data, the feasibility of engineering application of domestic new materials in the aircraft is confirmed.
