摘　　要：本文依托于某型号飞机冬季严寒地区停放的温度环境实测数据,研究了严寒地区地面停放飞机的温度诱发环境分析与预测的方法,确定了机内温度随外界自然环境温度的变化规律,基于统计归纳与传热分析方法,分别建立了能够准确预测飞机舱内温度的双层回归模型和多模式换热模型,并应用实测数据对预测模型精度进行了验证。最后,总结了严寒地域飞机温度环境分析与预测的方法,给出了不同预测方法的对比与选取建议,并对研究应用进行了展望,为提升航空装备低温环境适应性、优化环境试验条件与精准保障提供了一个有效途径。Based on the measured data of the temperature environment that the aircraft parked in the cold area in winter,this paper studies the method of temperature-induced environent analysis and prediction that aircraft parked in the cold area,determines the change law of the temperature inside the aircraft with the temperature of the external natural environment,and establishes a bilayer regression model and a multi-mode heat exchange model that can accurately predict the temperature in the cabin of the aircraft based on the statistical induction and heat transfer analysis methods,and verifies the accuracy of the prediction model by applying the measured data.Finally,the methods of analysis and prediction of the environment in which the cold temperature is lower than the aircraft temperature are summarized,the comparison and selection suggestions of different prediction methods are given,and the research application is prospected,which provides an effective way to improve the adaptability of the low temperature environment of aviation equipment,optimize the environmental test conditions and accurate guarantee.
