火箭弹垂直发射动力学建模与仿真

首先建立了火箭弹垂直发射的弹道模型,然后研究了升阻比、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,在一定程度上增大了升阻比,有助于增大火箭弹的射程;另外在转弯结束时,弹道倾角的变化对火箭弹射程也有一定影响。

Modeling and Simulating of Rocket Projectile Dynamic Vertical Launch

In the rocket projectile flight,some time go on attitude control can improve rocket projectile performance.At first the ballistic model of rocket projectile vertical launch is established,then it researches lift-to-drag ratio and influence of the angle of flight path on the firing range.At last,both instances go on simulating.The results of simulation indicate some increase of lift-to-drag ratio to make for increasing the rocket projectile firing range in sliding flight.In addition,the influence of trajectory angle change on the rocket projectile firing range when the turning is finished.
