Abstract: |
An application of a low frequency dry coupled penetration method in the detection of the internal bonding quality of the thermal insulation structure of the solid rocket motor was introduced in this paper. A contrast test block was designed to calibrate the detection sensitivity of the method. And the method was used to detect the actual products. It is proved that the method is suitable for the detection of the internal bonding quality of the thermal insulation structure. |
