随着国际适航组织对适航法规的不断修正和完善,危险情况下对机翼油箱及相关系统安全和客舱的保护成为民用飞机设计的主要关注和研究领域。同时,以波音公司和空客公司为主要大型商用飞机制造商竞争格局的形成,动力装置翼吊布局成为在役飞机最主要的动力装置布置形式,在这种条件下,应急情况动力装置、吊挂、机翼油箱结构的安全性设计和客舱安全及飞机经济性成为摆在每一个飞机主制造商面前的一对矛盾,也成为适航局方的主要的关注问题。
With the continuous revision and improvement of airworthiness regulations by international airworthiness organizations, the protection of wing tanks and related system safety and cabin in dangerous situations has become the main concern and research field of civil aircraft design. At the same time, with Boeing Company and Airbus as the major commercial aircraft manufacturers, the competitive landscape is formed. The layout of power plant wing suspension has become the most important power plant layout of active aircraft. Under such conditions, the emergency power plant and crane Hanging, the safety design of the wing tank structure and cabin safety and aircraft economy have become a contradiction in front of every aircraft main manufacturer, which has also become a major concern of the Airworthiness Authority.
