曲线运动导弹的尾焰模拟研究

Research on Simulation for Missile Exhaust Plume in Curvilinear Motion

根据预置曲线运动导弹的轨迹,应用粒子系统对曲线运动导弹的尾焰进行模拟研究。为使模拟效果更逼真,研究了公告板技术、纹理映射技术和融合技术。应用公告板技术对粒子系统进行了优化,应用纹理映射技术和融合技术对火焰粒子进行渲染。模拟结果表明,导弹尾焰能随预置的导弹曲线轨迹运动且保持与曲线相切,且在任意视点观察时都具有真实感效果。

According to the missile trail with preset curvilinear motion, the missile exhaust plume is simulated by using particle system. In order to realize more realistic results of simulation, the research is made on ways to apply billboard technology, texture mapping technology and blending technology. Billboard technology is applied to optimize particle system, and texture mapping technology and blending technology are applied to render the particles of missile exhaust plume. The results of simulation show that the missile exhaust plume can move together with the missile in preset curvilinear motion and can keep tangent to the preset curve, so that the realistic simulation effect can be achieved from any viewpoint.
