| Abstract: |
| Service life system of aircraft was introduced. The service environment and service life of typical aircrafts were elaborated. The corrosion cases of typical aircraft structures were listed, and the causes of corrosion failure were analyzed. Based on the comprehensive analysis of the corrosion and calendar life questions of aircraft in our country, it was concluded that corrosion is the main damage mode led to aircraft structural failure and is also the main factor seriously affecting flight safety and economic repair of aircraft. Some focal point questions of calendar life and corrosion protection of aircraft structures were discussed. |
