为指导单翼末敏弹的结构设计,分析了单翼末敏弹弹体和单翼间的安装连接方式,定义了三个翼安装角,给出了翼安装角的力学描述方法。利用基于四元数法的动力学模型,以某型单翼末敏弹的结构参数和气动参数为依据,仅改变翼安装角进行数值积分计算,得到了扫描角、扫描频率、下降速度和扫描间距与三个翼安装角间的关系。结果表明,在其它参数不变的情况下,三个翼安装角对扫描角、扫描频率、下降速度和扫描间距均有很大影响。

In order to guide the structure design of the single-fin Terminal Sensitive Ammunition (TSA), the installation and connection mode between the projectile and the single-fin was analyzed. Three fin-setting-angles were defined, meanwhile their mechanical description method was given. Using the dynamic model of quaternion method, based on the structural and pneumatic parameters of a certain type TSA, the numerical integral calculation was performed during which only the fin-setting-angle changed. The relationship between scanning angle, scanning frequency, falling speed, scanning interval and the 3 fin-setting-angles was achieved. The results show that the three finsetting-angles have a great influence on the scanning angle, scanning frequency, falling speed and scanning interval when other parameters are unchanged.
