摘　　要：研究了增程弹丸气动布局对弹道增程效果的影响,主要是针对弹丸有无舵片以及安装舵片的位置两种情况分析,建立对应的弹体模型,并对其进行气动仿真,得出相应的升力系数和阻力系数,并计算出升阻比,进而判断有无舵片以及舵片的安装位置对弹道增程效果的影响.仿真结果表明:有舵片相对无舵片的弹丸增程效果明显,升阻比最多增加25.17%,最少增加0.49%;舵片安装位置不同,其增程效果也存在明显差异,并且升阻比在距离弹头90 mm时增加最为明显.因此认为在满足全弹气动布局、飞行稳定的基础上,在弹丸适当位置安装舵片并相应改变攻角,可有效增加弹丸射程.This paper studies the influence of the extended range projectile aero dynamic layout for the in creased range on the trajectory mainly in two cases,whether there is a rudder piece and the positian of the rudder.For each cases,this paper established the corresponding models and carried on the odynamic simmlation.By the simulation,we got the lift coefficient and drag coefficient calculated lift to drag ratio,and then determine the influence of two cases.Srmnlation results show that increasing arudder piae has an obvious effect than without a rudder piece,lift-drag ratio increased by 25.17% at most and 0.49 at least.Its extendedrange effects are obviously different with the different position of rudder and the lift to drag ratio has the most signiticant corease when it was 90 mm from the warhead.Therefore,based on the aerodynamic layout and flig stability,installing a rudder piece at corresponding position and changing angle of atlack,which can effectively increase the projectile range.
