GJB 150.3A高温试验方法的应用及分析

摘要

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 relation and discrimination between GJB 150.3A and GJB 150.3 were introduced. Some technical points involved in this test method were analyzed, including tailor of test item, choice of test program, selection of test condition, and arrangement of test sequence. As an example, the way to use this test method for a kind of helicopter′s antenna was thoroughly illustrated. Finally, the technical development trend was discussed.
