    • Within the tactical operating distance, the projectile body in a short-range projectile ought to exhibit as far as possible the same performance characteristics as the corresponding normal or full-range projectile. To bring about the short flight path of the short-range projectile during travel of the projectile along its flight path, the following range shortening variants are applicable: (i) the projectile nose is formed of a suitable plastic material, the surface thereof being subject to considerable change under the action of air friction during flight such that the air resistance or drag increases and the flight path is shortened, particularly in the subsonic range; (ii) the projectile surface is covered or coated at least at preselected locations with a layer of suitable plastic material, such layer being subject to considerable change or erosion under the action of air friction, whereby the air resistance or drage increases and the flight path is shortened; and (iii) the projectile surface is roughened or provided with suitable grooves and smoothened by means of a layer of appropriate plastic material, such layer disappearing or disintegrating under the action of air friction during flight and the original roughened or grooved projectile surface bringing about a shortening of the flight path.
    • 在战术作战距离内,短距离射弹的射弹体应尽可能与相应的正常或全射弹相同的性能特征。 为了在射弹沿其飞行路线行进期间实现短程射弹的短程飞行路径,以下范围缩短变体是适用的:(i)射弹鼻子由合适的塑料材料形成,其表面为主体 在飞行期间的空气摩擦作用下发生相当大的变化,使得空气阻力或阻力增加,并且飞行路径被缩短,特别是在亚音速范围内; (ii)抛射体表面至少在预选位置被覆盖或涂覆有一层合适的塑料材料,这种层在空气摩擦的作用下经受相当大的变化或侵蚀,由此空气阻力增大,飞行路径 缩短了 和(iii)抛射体表面被粗糙化或设置有合适的凹槽,并且通过适当的塑料材料层进行平滑,这种层在飞行期间在空气摩擦的作用下消失或分解,并且原始的粗糙或凹槽的抛射体表面带来了 缩短飞行路线。
