Cluster Analysis for Typical Ground Environment Areas of Civil Airports and Regional Difference Analysis for Corrosion of Civil Aircrafts

Based on the corrosion data of a series of aircraft for recent 10 years, meteorological and environmental indicators of aircraft base airports, using dynamic clustering method, the environmental areas of aircraft base airports were divided firstly, and then four types of corrosion environment area for corrosion behavior of this series aircraft were got out with similar affecting laws. Secondly, the corrosion frequency of different types of airport environment was investigated by analysis of variance. The results show that the aircraft corrosion frequency in different airport environments varied as region varied. This research provides an important reference for working out a civil airport environment spectrum and selecting the parameters for the acceleraed corrosion testing.
