摘要
Abstract
According the principle of slowdown depending on increasing resistance, this paper designs one￣dimensional trajectory correction projectile,and establishes the 3d model of projectile and correction mechanism. Combined with external bal istic theory and correction mechanism working characteristics,fluid dynamics software FLUENT is used to establish the one dimensional trajectory correction shel bal istic simulation model,then the simulation analysis of the flow field around a fixed grenade is done and the high explosive shel ’ s resistance, viscous force, resistance coefficient and viscosity coefficient are obtained, therewith its correction ability is analyzed by contrast, Theoretical basis is provided for the engineering design of the correction mechanism.关键词
