前言近年来,在从事高低压发射火箭的课题研究中,由于要探讨炮口速度对射击密集度、射程等的影响,面临着大量的理想外弹道计算任务。然而,按《外弹道学》(我院203教研室,1973.7,下同)的方法作计算,采用逐次逼近、查表插值及西亚切解法等等,都很麻烦,且不太准确。 为了提高计算效率和计算精度,我们编拟了这份适用于DJS—6机的通用源程序。它既适用于火箭,又适用于普通炮弹;既适用于开式发射火箭,又适用于闭式发射火箭;既适用于大射角,又适用于小射角。由于仅要求用它来作弹道方案选择,故未考虑弹道修正计算问 Preface In recent years, in the research of high and low pressure rockets launched, due to the influence of muzzle velocity on firing intensity, range and so on, there are a large number of ideal external ballistic computation tasks. However, it is cumbersome and not accurate to calculate by the method of “outer ballistics” (203 Department of our hospital, 1973.7, the same below) using successive approximation, look-up table interpolation and Western Asia tangent method. In order to improve computational efficiency and computational accuracy, we have compiled this universal source program for DJS-6 machines. It applies to rockets, but also for ordinary shells; both for open-launched rockets, but also for closed-launched rockets; both for large angle, but also for small angle. Since it is only required to use it for ballistic option, ballistic correction calculation is not considered
