With the increasing effects of corrosive environment on the aircraft structures, calendar life has become a severe trouble of the air force at present and in the future. In this paper, the engineer background, the core technology, the existing status quo and the problem of the military aircraft calendar life at home and abroad were expounded. Several key problems were studied emphatically, such as corrosion feature, corrosion mechanism, failure mode, probabilistic distribution and development of corrosion d...
