【 摘 要 】

The civil aircraft must have the ability to the global operation. The aircraft may experience the high temperature, the low temperature, the high humidity, ice and other extreme climatic environment. Environmental worthiness plays an important role in the integrated capability of the civil aircraft. Environmental worthiness evaluation is a major part of the civil aircraft engineering. According to the environmental worthiness to diversified environmental factors, we can establish the criteria for environment classification. The environmental worthiness model of the civil aircraft was set up using the grey theory. The rationality and feasibility of the model was validated by the example. The results indicate that the environmental adaptability of the aircraft was ranked "poor" to "better". The result can supply the reference data for the environment adaptability requirement for thedesign of the civil aircraft.
