摘要
本文针对弹丸滑翔飞行的运动特性 ,根据能量守恒原理 ,采用能量分析法对弹丸在滑翔段的弹道特性进行了研究。分析了弹丸理想滑翔飞行弹道的特点 ,推导出弹丸实现滑翔飞行的必备条件 ,以及弹丸滑翔飞行距离的计算公式、计算方法以及近似估算公式 ,对滑翔飞行初始时刻的选择进行了初步讨论。
A study on the trajectory properties of a gliding projectile was done according to the energy conservation law. The necessary conditions for gliding flight were deduced, and the method of calculation, approximate formula for estimating the gliding range were also proposed. At the same time, selection of the initial time of the gliding flight was discussed. The results are meaningful to the design for the gliding projectile regarding the aerodynamics and the control system.
