针对普通高速旋转弹丸低命中率问题,建立了有舵弹丸与无舵弹丸数值仿真模型。仿真研究了有舵弹丸相对无舵弹丸关于阻力、升力、滚转力矩及其系数以及射程和横偏的影响,结果表明:在保证弹丸飞行稳定的基础上,有舵弹丸在减旋情况下相对于无舵弹丸射程、射高､横偏减小;适当控制鸭舵姿态可以修回安装鸭舵机构带来的射程损失,同时对发生偏离弹丸进行有效修偏。

In the issue of the accuracy of common high speed rotating projectile accuracy was low, the numeric simulation model of projectile with canard rudder and the non rudder projectile was established. The simulation of the influence of rudder projectile on non-rudder projectile about drag, lift, rolling moment, its coefficient, range of fire and the lateral misalignment showed that on the base of projectile flight stability, in the anti rotation case, the range of projectile, the height and the transverse deflection of the rudder projectile relative to the non rudder projectile were reduced. Proper control of the canard rudder attitude could repair the range loss caused by the installation of the canard rudder mechanism and could repair the deviation of the projectile effectively.
