摘　　要：国际上航空发动机制造商多采用等效安全的方法表明其型号设计对特定条款的符合性。以GE公司获得型号合格证的GEnx系列航空发动机为典型案例,针对通常符合性表明难度较大的FAR-33.27条款,在剖析其对应型号合格证数据单的基础上,分析等效安全表明技术方法并在此基础上概括出关键技术和准则要求,即经验证的自主分析方法、前期已取证型号的支持、替代性技术方法的相似准则要求。研究结果可为我国民用航空发动机研制中条款可能的等效安全表明方法以及未来型号合格审定提供参考和借鉴。The international aero-engine manufacturers usually adopt the method of equivalent level of safe-ty(ELOS)to present the compliance of airworthiness requirements.GEnx series aero-engines were consid-ered as a typical case to analyze the technical method of ELOS for FAR-33.27 in airworthiness certifica-tion.Results show that critical technique methods and criterion requirements can be summarized as the veri-fied GE design practice methodology,the support from earlier certificated aero-engine and the similarity criterion requirements for proposed alternative method.The conclusions provide the reference for possible ELOS technical methods and support for the future certification process of China.
