69(Ⅰ)式40火箭弹是在69(Ⅰ)式火箭弹的基础上改进后定型生产的一种新型火箭弹,该弹由于战斗部的形状、装药量的大小,初速的大小以及弹道形状和不同距离上的弹道高与69(Ⅰ)式火箭弹有较大变化,因此,该弹使用69式火箭筒射击,按照发射69(Ⅰ)式火箭弹的要求进行校筒和装定射击诸元,射弹普遍打低。据我们对射弹偏差情况的统计,在正常情况下对300m距离上的目标射击,全部射弹的平均偏差量约
69 (Ⅰ) Type 40 Rocket is a new type of rocket that is modified and finalized on the basis of Type 69 (Ⅰ) rockets. Due to the shape of the warhead, the amount of charge, the size of the initial velocity and the trajectory The ballistic height and shape of the rockets at different distances vary greatly from those of type 69 (I) rocket launchers. Therefore, the bomb uses a 69-type rocket launcher to carry out school-shooting and setting firing of various types of rockets in accordance with the requirements for launching 69 (I) , Projectiles generally lower. According to our statistics on the deviation of the projectile, under normal circumstances, the average target deflection of the projectile at a distance of 300m is about
