Abstract: It researches missile operational system simulation experiment, in view of the problem that when using Vega Prime’s particle system module for the simulation of missile efflux plasma which is moving with high speed, the particles are discrete that impact the simulation visualization effect. In order to solve the missile efflux plasma simulation problem, it proposes the solution that using Vega Prime together with OpenGL. It models the missile efflux plasma based on the particle system principle, applies OpenGL into Vega Prime according to the event issued subscription mechanism of Vega Prime. The efflux plasma that simulated by the proposed method is shape lifelike and sporty. It meets the demands of the instantaneity and authenticity in the simulation and solves the defect of simulating missile efflux plasma by Vega Prime.

摘要： 研究基于Vega Prime的导弹作战系统仿真实验，针对使用Vega Prime的粒子特效模拟高速飞行导弹尾焰会出现尾焰不连续而影响仿真可视化效果的问题，提出将Vega Prime与OpenGL相结合的方法。基于粒子系统基本原理，对导弹尾焰进行建模；依据Vega Prime的事件发布订阅机制将OpenGL引入到Vega Prime中。模拟的尾焰形态逼真，动感十足，满足仿真实时性与真实性要求，解决了Vega Prime模拟导弹尾焰存在缺陷的问题。
