摘要
为了研究鸭舵式修正机构的修正能力,建立了不同舵高和不同舵偏角的二维弹道修正弹丸三维模型,采用了流体动力学和运动学的联合仿真,重点分析了弹丸的升阻比气动特性、舵片减旋和姿态控制,得出修正效果。得出结论:50 mm高的舵片对射程的修正效果最好,55 mm高的舵片对偏航的修正效果最好;舵偏角越大的舵片对射程和射高的修正效果越好,但对航偏的修正效果不佳,而偏角较小的舵片对航偏的修正效果较好。
In order to study the correction ability of the canard correction mechanism, establishing 3D models of two-dimensional trajectory correction artillery with different heights and different rudder angles and conducting fluid dynamics and kinematics simulation. Using hydro- dynamics and kinematics co-simulation, analyzing aerodynamic characteristics, anti-rotation and position-control of rudder specially. Draw- ing a conclusion ： the rudder with 50 mm height makes the correction-resuh of range best, the rudder with 55 mm height makes the correc- tion-result of deviation best ; the bigger rudder angle, the better the correction-resuh of rang and cross, but the correction-result of deviation is not good and the smaller rudder angle makes the correction-result of deviation better.
