| Abstract: | Numerical simulation of shock response of the flight structure for laser propulsion is carried out for single pulse and multi-pulse using the commercial code ABAQUS.The method that solved the focal area of deforming parabolic of revolution was established.The results show that the change of the focal area due to structure deformation can not be ijnored,this should be considered in designing the flight vehicle. |

| Keywords: | Laser propulsion Shock response Focal area |
