摘　　要：航空发动机延程运行(ETOPS)资格是飞机延程运行的基础,为了给国内航空发动机ETOPS型号设计及适航符合性验证提供指导,研究ETOPS适航规章形成的历程及航空发动机早期ETOPS资格的设计和试验要求。分析发动机ETOPS适航条款与飞机ETOPS适航条款的关系,提出一种民用航空发动机ETOPS型号的设计及符合性验证方法。结果表明:本文提出的验证方法为指导民用航空发动机早期ETOPS型号设计和符合性验证提供了依据。Aircraft engine extended operations(ETOPS)eligibility is the basis for aircraft extended operations.In order to provide the guide for the domestic aircraft engine ETOPS type design and airworthiness compliance verification,the formation process of the ETOPS airworthiness regulation and the design and test requirement for aircraft engine early ETOPS eligibility are studied.The relationship between the engine ETOPS regulation and aircraft ETOPS airworthiness regulation is analyzed.An aircraft engine ETOPS type design and compliance verification method is proposed.The results show that the proposed verification method in this paper can provide a reference for early ETOPS type design and compliance verification of domestic civil aircraft engine.
