飞机实验室低温试验方法研究

Low Temperature Test Method for Aircraft in Climatic Laboratory

为了在实验室内进行飞机整机的低温试验,对低温试验方法进行了研究。通过分析国内外相关低温试验标准和国外飞机实验室低温试验,从试验目的、试验特点、试验条件、试验控制、试验科目、试验步骤、试验中断处理等方面,研究了飞机实验室低温试验方法。应用该试验方法,在国内首次完成了某型飞机的实验室低温试验,试验内容涵盖飞机系统、飞机地面保障设备和飞机地面保障程序,获得了在外场试验难以甚至几乎无法获得的试验数据。研究的试验方法适用于飞机实验室低温试验,将有助于我国飞机低温环境适应性设计。

The work aims to study the low temperature test method to test full-scale aircraft at the low temperature in climatic laboratory.Through the analysis on low temperature test standards at home and low temperature test methods for aircraft in climatic laboratory abroad,the low temperature test method for aircraft was studied from test object,test characteristic,test severity,test control,test subject,test step,test interruption,etc.Based on this method,a full-scale aircraft was tested at low temperature in climatic laboratory for the first time in China,including aircraft systems,ground protection equipment and maintenance program.The test data which were difficult or almost impossible to obtain in field tests were also obtained.The proposed test method is applicable to full-scale aircraft test at low temperature in climatic laboratory and conducive to aircraft adaptability design in low temperature environment.
