运8系列飞机结构定寿属国家“九五”重点型号科研项目,是我国首次大中型军民用运输机的结构定寿。它需要同时满足国军标和民用航空器适航条例,是一项跨学科、多领域、综合技术难度与复杂程度极高的系统工程。通过对机体结构进行疲劳定寿,给出了运8系列飞机结构的使用寿命,为型号研制积累了宝贵经验。
Yun 8 series of aircraft structure Ding Shou is a national “Nine Five” key scientific research projects, is China’s first large and medium-sized military and civilian transport aircraft structure Ding Shou. It needs to meet both the national military standard and the airworthiness regulation of civil aircraft at the same time. It is an interdisciplinary and multidisciplinary systematic project with extremely high technical difficulty and complexity. Through the fatigue life of the body structure, gives the service life of Yun 8 Series aircraft structure, accumulated valuable experience for the model development.
