Structure Design And Simulation Techniques Of Twice Throwing On Aerial Submunition

This paper presents experimental and computer simulation studies of the twice throwing structure of aerial submunition. The main points are as follows:1) Experiment researchThe twice throwing system structure of the aerial submunition has been designed according to the technical target, including the external-combustion type gasbag throwing system and the central tube bursting-type throwing system. The experiment studies of the gas-charge experiment of the gasbag and the throwing experiment of the sub system have been carried out, then find out the effect of the correlative parameters . Via studies of experiment and theory, make the throwing system perfect at last.2) Theoretical researchBased on the classic interior ballistic theory and exterior ballistic theory, the theoretical models in the throwing procedure of cargo-projectile have been established. The affection of several designing parameters on throwing performance of the throwing system , the flying stabilization and moving laws of sub-projectiles have been studied. According to the theoretical research, the throwing system structure is optimized. The theorial results show that the technical target is achieved by using the throwing system presented in this paper.
