摘要:
为了研究修正组件反旋与不旋对弹箭气动特性的影响,在CFD软件中采用滑移网格方法对双旋二维弹道修正弹在不同攻角、马赫数下的气动特性进行了数值模拟,得到了气动特性变化规律,研究了鸭舵在不同滚转角下弹箭的修正能力,着重分析了修正组件反旋与不旋时该弹气动特性的差异。研究表明,修正组件反旋以后阻力系数与升力系数有所下降,非零攻角下该弹始终会有侧向力存在,通过控制同向舵的周向位置可以对射程和飞行方向进行修正。
Abstract:
In order to study the effect of reverse-rotation and non-rotation PGK on the aerodynamic characteristics of missile,moving mesh provided by CFD software was used to simulate the dual-spin two-dimension trajectory correction projectile(TCP)at different angles of attack and Mach number,and the change law of aerodynamic characteristics was obtained. The correction ability of canards at different roll angles was studied. The difference of the aerodynamic characteristics of TCP was analyzed in the case of reverse-rotation and non-rotation PGK. The research shows that the drag coefficient and the lift coefficient decrease while the PGK rotating reversely,and the projectile always has lateral force under the nonzero angle of attack,but the distance and direction of the flight can be corrected by controlling the circumference position of symmetrical rudders.
