介绍了GJB 150.3A高温试验方法的由来以及与GJB 150.3之间的联系和区别。重点对该方法中试验项目的剪裁、试验程序的选择、试验条件的确定以及试验顺序的安排进行了分析,并以某型直升机机载天线为例,详细说明了该试验方法的应用,最后就其未来发展趋势进行了探讨。
The origin of GJB 150.3A high temperature test method and the connection and difference with GJB 150.3 are introduced. This paper mainly focuses on the tailoring of test items, the selection of test procedures, the determination of test conditions and the arrangement of test sequences in this method. Taking a helicopter airborne antenna as an example, the application of the test method is described in detail. Finally, Its future development trend is discussed.
