原苏联民航飞机耐久性和损伤容限设计与试验技术发展概况

 根据1991年中苏首届航空结构强度学术交流会上原苏方的有关技术报告,简单地综述了原苏联飞机结构耐久性和损伤容限(包括热应力)分析方法和试验方法。这些方法建立在正确的理论分析及大量的试验和使用经验基础上,合理地确定新机的寿命期限和逐步地延长在役飞机的寿命期限,确保飞机结构的完整性。

THE GENERAL SITUATION OF DESIGN AND TEST TECHNIQUE DEVELOPMENT ON CIVIL AIRCRAFT DURABILITY AND DAMAGE TOLERANCE OF PREVIOUS USSR

According to the relative technical reports of previous Soviet Union in procceedings of the first sino-soviet symposium on aircraft structure strength, 1991, the analysis and test methods on durability and damage tolerance (involving thermal stress) of aircraft structures in previous USSR are simply summarized in this paper. The methods are based on correct theoretical analysis and a lot of tests and servicing experience. By means of the methods, the life limit of a new aircraft is properly determined and the life limit of a servicing aircraft is extended step by step and aircraft structure integrity is ensured.
