Analysis on Dynamic Characteristics of Jet Flow During the Separation of Cluster Munition
摘要
Abstract
In order to analyze the effect of jet interaction on the dynamic characteristics during the gasbag separation of cluster munition,the three-dimensional dynamic model was built,and the flow field of the cluster munition under the action of combustion gas interference was simulated in the different places of the gasbag based on the statistical results of gasbag experiments. The interaction process of separation between the gas jet and the flow was reveled,and the effect of the jet flow on the dynamic characteristics of the bullets was analyzed. Numerical simulation results show that the action process for the bullets is about 15 ms caused by the initial jet flow disturbance,and the parameters of the aerodynamic separation show intensive nolinear characteristics. The effect of the gas interference on the bullets is different because of the location of jet.关键词
