Aiming at the problem of large pore defects (Φ20~Φ40mm) contained in the solid rocket motor grains, according to the X-ray inspection results, one of the grains was selected to establish a three-dimensional model with pores.
In view of the problem that the solid rocket engine drug column contains atmospheric hole defects (20 to 40mm), according to the results of X-rays, one of the drug columns is selected to establish a three-dimensional model with pores.
According to the results of X-ray inspection, a three-dimensional model of a solid rocket motor grain with large pores (Φ 20 ~ Φ 40mm) is established,<br>
