弹道图的作用与射表相同,由于是曲线形式,所以称弹道图。本文对小型气象火箭运动的动力学方程组进行了探讨。提出了风权、弹道风的概念及其计算公式,以及如何利用运动方程的数字电子计算机结果绘制风权曲线、风补偿曲线。同时介绍了弹道图的功能与使用方法,并以某批次飞行试验为例说明利用弹道图方法预报弹道的精度。最后,为计算箭体及不开伞的箭头(在开伞有故障情况下)的实际落点,提出了进行弹道验算的简便方法。
The function of the ballistic map is the same as that of the shooting surface. Since it is in the form of a curve, it is called a ballistic map. In this paper, the dynamics equations of small meteorological rocket movement are discussed. The concept of wind power and trajectory wind and its calculation formula are put forward, and how to draw the wind power curve and wind compensation curve by using the digital computer results of motion equations. At the same time, the function and usage of the ballistic map are introduced. Taking the flight test of a certain batch as an example, the accuracy of the trajectory prediction by the ballistic map method is illustrated. Finally, in order to calculate the actual landing point of the arrow and the parachute arrow (in the case of a parachute failure), a simple and convenient method of ballistic checking is proposed.
