摘要
在弹丸稳定飞行的假设条件下 ,根据弹丸滑翔飞行的特点 ,建立了滑翔段弹丸运动的数学模型。在小扰动前提下推导出描述弹丸扰动运动的状态方程 ,据此分析了滑翔段弹丸飞行的一些固有特性和操纵特性 ,推导出滑翔段弹丸的倾角随攻角的变化关系 ,所得结果对于滑翔弹丸的设计具有一定的参考价值。
Mathematical model of motion for a projectile in the gliding phase is established on the assumption that it flies steadily, according to the characteristics of flight of the gliding projectile. The state equations of the projectile under disturbed motion are derived under the assumption of small disturbance, and some natural characteristics and manipulative characteristics of the flying projectile in its gliding phase are also analyzed. The variable relation of the projectile's obliquity and angle of attack is finally derived. The results presented are of reference value for the design of the gliding projectile.
