前言当前,野战火箭武器性能是否赶上或超过世界先进水平,主要衡量指标之一,是其射击密集度。因此,在研制过程中,特别是在作参量方案选择时,往往需要算出方向密集度随一个或几个参量的变化曲线,以寻求最佳方案。这就需要大量地进行密集度的理论计算。然而,按目前外弹道学教科书的手工计算方法,即使只算出密集度随一个参量的变化曲线,计算工作也相当繁重。况且,按参考资料[1]的方法,计算精确度很难预定,特别是对弹体有自转运动(低旋尾翼弹和涡轮弹)时求解推力偏心引起的角散布的方法,是以近似处理为前提
Foreword At present, whether the performance of field-propelled rocket weapons catch up with or exceed the world’s advanced level is one of the main measures of their firing intensity. Therefore, during the development process, especially when selecting the parameter scheme, it is often necessary to calculate the curve of the directional density with one or several parameters to find the best solution. This requires intensive theoretical calculations. However, according to the current manual calculation method of the outer ballistics textbook, the calculation work is rather heavy even if only the variation curve of intensity with one parameter is calculated. Moreover, according to the method of reference [1], the calculation accuracy is hard to predict. Especially for solving the angular dispersion caused by thrust eccentricity when the projectile has self-rotating motions (low-mantle and turbo-bomb), the method of approximate processing As a prerequisite
