Numerical Simulation And Experiment Study Of Mine Throwing

This paper mainly presents the throwing technology of the air-dropping mine, including the design of the throwing system structure, the experimental study, the establishment of the mathematic-physical model and computer simulation. The main points are as follows:1) Structural design and experiment researchAccording to the study objective and the technical target, the throwing system structure of the air-dropping mine has been designed, and the experimental studies of opening and throwing has been finished. The experimental results show that the tactical and technical targets is achieved by using the gasbag throwing structure of the external-combustion and the downward throwing design.2) Theoretical researchBased on the classic interior ballistic theory and exterior ballistic knowledge, the theoretical models of the mine throwing have been established. Then, the interpolation and Runge-Kutta methods are applied to obtain the numerical results of the model by Visual C++. The affection of several designing parameters on throwing performance of the throwing system , the flying stabilization and moving laws of the mine have been studied. According to the theoretical research, the throwing system structure is optimized.
