摘　　要：机载设备的环境适应性是民用飞机设计的一个重点研究方向。飞机在使用过程中会遭受各种液体,从而对机载设备产生不同程度的影响。基于气候环境数据和飞机实际使用场景,依据飞机结构特征,定义了民用飞机液体环境和分区,分别对不同的分区进行液体环境分析和研究,制定了机载设备的防水、流体敏感性和结冰等液体环境试验要求,可应用于机载设备液体环境适应性评估与验证。In the actual design of civil aircraft,the environmental adaptability of airborne equipment is a key re⁃search direction.The aircraft will be subjected to various fluids during the operation,which will have different de⁃grees of influence on the airborne equipment.This paper defines the civil aircraft liquid environment and partitions based on climate environment data and actual aircraft operating environment,based on the structural characteris⁃tics of the aircraft,and analyzes the liquid environment of different partitions respectively,and formulates the liq⁃uid environment test requirements such as waterproofness,fluids susceptibility,and icing of the airborne equip⁃ment,which can be applied to the assessment and validation of the liquid environment adaptability of the airborne equipment.
