    • A cylindrical device connected to the nose of a projectile for imparting n to the projectile fired from a non-rifled bore of a cannon. The device has at least two coaxial, adjacent, and integrally connected cylindrical segments of different diameter. The segment having the larger diameter is positioned most rearwardly of the projectile, relative to the nose of the projectile, and the periphery of this segment has circumferentially spaced angled slots for catching air moving past the projectile to spin the projectile. The segment with the smaller diameter attaches the cylindrical device to the aft end of the nose of the projectile and directs the flow of air to and through the angled slots of the segment having the larger diameter.
    • 连接到射弹的鼻子的圆柱形装置,用于从炮的非膛孔射出的射弹旋转。 该装置具有不同直径的至少两个同轴,相邻和一体连接的圆柱形段。 具有较大直径的段相对于射弹的鼻部位于抛射体的最后面,并且该段的周边具有周向间隔开的成角度的狭槽,用于捕捉通过射弹移动的空气以旋转射弹。 具有较小直径的段将圆柱形装置附接到射弹的鼻部的后端,并将空气流引导并穿过具有较大直径的段的成角度的槽。

    • The missile (10) comprises at its rear end in flying direction (A) tail f (14, 16, 18) whose front edges (14F, 16F, 18F) are sharpened at both sides. Intermediate the tail fins, outflow openings (22) are arranged on the body (12) to eject therethrough fuel into the supersonic external flow forming about the body (12). Due to supersonic flow, there are generated shock wave fronts extending from the front edges (14F, 16F, 18F) and being reflected by adjacent tail fins, said shock waves of the shock wave fronts interfering with the supersonic flow passing along the body so that recirculation fields are formed between the tail fins. The said recirculation fields are formed within the range of corner flow and outlfow openings (22) so that fuel discharged from the latter is burnt down with the formation of a locally stable flame. As a result of the volume increase resulting from the combustion, a high-pressure area develops between the tail fins. The pressure produces a force directed transversely to the flying direction and causing a control of the missile (10).
    • 导弹(10)在其后端沿飞行方向(A)包括其前边缘(14F,16F,18F)在两侧被锐化的尾翼(14,16,18)。 中间的尾翼,流出口(22)布置在主体(12)上,以将燃料喷射到围绕主体(12)形成的超音速外部流中。 由于超音速流动,产生从前边缘(14F,16F,18F)延伸并被相邻尾翼反射的冲击波阵面,所述冲击波前面的所述冲击波干扰沿身体传递的超音速流动,使得 在尾翼之间形成再循环场。 所述再循环场形成在角流和外侧开口(22)的范围内,使得从后者排出的燃料燃烧形成局部稳定的火焰。 由于燃烧引起的体积增加,在尾翼之间形成高压区域。 压力产生横向于飞行方向的力并引起对导弹的控制(10)。
