考虑到单翼末敏弹的稳态扫描段对其作战效能的影响至关重要,结合其强非对称的气动力结构参数,利用基于四元数法动力学方程的计算机仿真,逐一列举并探讨了翼长、转角、弹重、翼端物重和弹体相对中心对称轴转动惯量对铅直落速、扫描频率、扫描角及扫描间距的影响。仿真结果表明通过调整上述结构参数可以得到理想的扫描参数,其规律也为设计满足具体实战环境所需的单翼末敏弹提供了较好的理论依据。

For the importance of the stable scanning phase in the single-fin TSA' system efficiency, the computer simulation which is based on using quaternion to represent the Euler kinematics was used to list and analyze the strong asymmetric aerodynamic force structure's impacts to this phase. The vertical falling velocity, scanning frequency, scanning angle and scanning distance can be influenced by the variation of the single-fin's length, angle, the weight of the ammunition, the heavy object's weight on the single-fin and the ammunition's moment of inertia to its central symmetry axis. The computer simulation results show that the ideal scanning parameters can be got by adjusting the structure parameters. The rules extracted from the computer simulation also provide significant theoretical foundation in the real single-fin TSA's design.
