火箭弹垂直发射的动力学建模与仿真
首发时间:2008-12-30
摘要:火箭弹在飞行过程中,在某些阶段进行姿态控制,有助于提高火箭弹的性能[1]。本文首先建立火箭弹垂直发射的弹道模型,然后研究升阻比、弹道倾角等参数的变化对火箭弹射程的影响,并分别对这两种情况进行了仿真。仿真结果表明,滑翔飞行时,在一定程度上增大升阻比,有助于增大火箭弹的射程。另外转弯结束时,弹道倾角的变化对火箭弹射程也有一定影响

Vertical Launching of Rocket Projectile Dynamical
Abstract:In the rocket missile flight , some time go on attitude control can improve rocket missile performance . At first the ballistic model of rocket missile vertical launch is established , then research lift-drag ratio and trajectory angle to influence of firing range . At last , the both instance go on simulink . The result of simulink indicate in some extend augment lift-drag ratio make for augment rocket missile firing range in sliding flight . In addition trajectory angle change to influence of rocket missile firing range in the turn around is finished .
Keywords: vertical launching lift-drag ratio trajectory obliquity range
