| Abstract: | For the interior ballistic process of kill element bag launching system of kill vehicle, a novel method using numerical simulation and experiment is proposed in this paper. The structure and the work principle of the bag launching system are explored. The projecting model is constructed using classical interior ballistic theory, and the gasbag volume and the valid thrust area models are built according to gasbag expanding. The results of numerical simulation and experiment prove the rationality of this model. The theoretical research methods are presented for the constructional design of bag launching system of kill vehicle. |
