在二维弹道修正方法的基础上,提出固定翼式二维修正弹的修正模型。针对大口径炮弹的飞行情况,设计了修正弹的物理模型。对炮弹及修正部整体三维建模,计算域六面体机构性网格离散。运用CFD流体计算软件,采用滑移网格计算技术对修正部及整体进行了计算分析,得出了修正部旋转舵力矩及控制舵力随马赫数的变化规律,为以后的固定翼修正方式的研究提供了气动依据。

A model of two-dimensional trajectory corrector shell with fixed-wing was proposed based on two-dimensional trajectory corrector method analysis. In view of large-caliber shell's flight situation, the wing shape of two-dimensional trajectory corrector shell was designed. Three-dimensional modeling was conducted for shell and the corrected part. The computation territory hexahedron was separated by structure grid. The CFD hydraulic design software and the slipping grid computation technology were used to compute and analyze the corrected and the whole. The change law of the corrected part's revolving control surface moment and the control rudder strength with the Mach was got, providing aerodynamic reference for future research of fixed wing correction.
