摘要
在无控火箭靶弹的基础上,加装控制舵片改装为有控火箭靶弹。建立简化的舵控火箭靶弹三维模型,并利用数值计算的方法采用Fluent软件对火箭靶弹的气动特性进行了仿真分析。通过仿真得到弹加尾翼(无控)和全弹(弹+翼+舵,有控)的气动参数在舵偏角为0°时随攻角、马赫数的变化规律,以及不同舵偏角下的压力云图。
In this paper,the rocket target without control is equipped with control rudder piece to be rudder control rocket target.The simplified model of a rudder control rocket target is established,by using Fluent software,the aerodynamic characteristics of the rudder control rocket target are simulated and analyzed,and the pneumatic parameters of the rudder control rocket target at rudder angle of 0degree are obtained,as well as the stress nephogram under different rudder angle.
