Study on Change Law of Scan Angle for Terminal Sensitive Projectile

扫描角及其变化规律是影响末敏弹系统性能和命中率指标的重要因素。文中针对末敏弹稳态扫描阶段运动特性,建立末敏弹在绕铅垂轴旋转主伞带动下围绕悬挂点运动的绕心方程,进而得出扫描角变化解析模型,通过解析模型得到影响扫描角的主要设计参数,并仿真分析这些设计参数对扫描角变化的影响规律。研究结果可为末敏弹扫描角参数设计提供依据。

The scan angle and its variation rule are important parameters affecting the performance and hit probability of the terminal sensitive projectile.In this thesis,the perturbation equation for the terminal sensitive projectile moving around the suspension point is established under the action of rotating main umbrella around the vertical lead axis,according to the motion characteristic of terminal sensitive projectile with stable scanning.The main parameters affecting the scanning angle are analyzed by establishing the analytical model of terminal sensitive projectile stable scanning motion.The effect of these parameters on the scanning angle is studied by analysis and simulation calculation.The results can provide basis for the parameter design of stable scanning.
