寿命无极限:飞机寿命管理新理念

Ultimate Service Life:New Concept for Aircraft Life Management

飞机的使用寿命问题归根到底是如何科学地解决飞机结构的飞行安全与经济使用的矛盾,而这个矛盾迄今仍是人类未能从根本上解决的世界性难题。通过对飞机使用寿命、寿命理念等问题的深入研究、探讨和ICMS创新技术的研制与应用,总结提出了以"寿命无极限"(L=X)为代表的飞机寿命管理新理念。指出寿命是用出来的而不是定出来的。对时兴的"老龄飞机"称法之合理性提出了质疑。对于飞机是否进入老化失效期的判断依据提出了3方面因素。阐述了用技术和经济指标综合评估确定飞机的使用寿命,是现代飞机设计制造与使用维修所发生的重要变化,是对维修管理的新挑战。新理念与新技术能够引发和推动飞机定寿、延寿和寿命管理的技术革命。与时俱进、更新统治人们意识的传统寿命理念,以积极的心态关注、应用新技术,掌握飞机使用寿命评估的话语权,是当今各层面管理者需要面对和重视之问题。

The topic of aircraft life management has always been the contradiction between flight safety and economic operation; and this conflict has been a global problem. Through the research and application of the term of life, aircraft life theory and ICMS technology, a new theory featured by ＇ultimate service life＇ （L =X） is raised. Life is determined by means of usage rather than defied; and this casts doubts on the term of ＇aging aircraft＇. Three factors are mentioned for the recognition of whether the aircraft has entered into the phase of aging and expiration. To estimate the life of aircraft jointly through the examination of technical and economic indicator is new phenomenon for modern aircraft design, manufacture and maintenance, meanwhile new challenge in the aspect of repair management. New concept and new technology introduce and promote technical revolution of recognition of aircraft life, life extension and life management. To keep pace with the times and update traditional aircraft life theory, pay attention to the application of new technique and keep right of speech is the problem faced by the administrators.
