Research on Type Design and Compliance Verification Method of ETOPS for Civil Aircraft Engine

Abstract

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.
