| Abstract: |
| Based on technical properties of industrial CT technology and the common defects of nozzle divergence cone insulation for the rocket motor, the quality of nozzle divergence cone insulation was investigated in this paper. The results showed that industrial CT had instructive significance in improving the quality of the nozzle divergence cone insulation and optimizing the corresponding preparation technology. Especially, the technology of 3-D reconstruction, which provides powerful support for the normal operation of the rocket motor, has better effect in product quality guarantee. |
