摘要
研究了用超声干耦合单面检测方法对固体发动机喷管复合材料扩张段进行阵地探伤的可行性和判伤标准。探讨了该方法对扩张段的探测能力及检测试件的最佳检测工艺条件 ,并给出了实验结果。
The feasibility and judgement standard of the positional defect inspection of nozzle composite divergence cone of SRM by means of dry coupling single side ultrasonic detection are investigated.The inspection ability of the method and optimal operation conditions for specimen are discussed and some tested results are given.
