    • A spin stabilized payload projectile 10, in order to separate a projectile base connected with projectile body 11 and to eject a payload 13, is provided with an ejection charge 15 in its nose region, with such ejection charge being activated with a certain delay by a nose fuze 14. To prevent damage to the nose fuze 14 by the gas pressure generated by ejection charge 15, a pressure reducing element 20 is disposed between nose fuze 14 and the ejection charge. In a particularly advantageous embodiment of the invention, this pressure reducing element 20 is composed of a cone or a cone frustum whose base face faces nose fuze 14 and whose tip faces ejection charge 15. The tip of pressure reducing element 20 is provided with an opening 20a through which a firing jet travels from nose fuze 14 to ejection charge 15 for the purpose of activating charge 15. After activation of ejection charge 15, pressure reducing element 20 is deformed into a substantially gas tight disc.

    • An improved twist brake for the separable payload of a twist or spin-stabilized flare or smoke projectile is described. A pair of pivotable wings, secured at one end to a portion of a central shaft of the payload, is normally engaged by the inner surface of a guide shoe which prevents contact of the wing with the separable housing of the payload. Cooperable projections and slots on the guide shoe and the central support shaft prevent substantial axial and circumferential movement of the shoe, while permitting outward movement of the wings and the guide shoes when the payload separates from the housing. During such separation, the guide shoe is also separated from the wings so that the latter can pivot to their maximum extent to provide an optimum rotational braking action on the payload.
    • 描述了用于扭转或旋转稳定的火炬或烟雾弹丸的可分离有效载荷的改进的扭转制动器。 一对可枢转的翼,一端固定在有效载荷的中心轴的一部分上,通常由引导靴的内表面接合,该导向板防止翼与有效载荷的可分离壳体接触。 引导靴和中央支撑轴上的可协调的突起和槽防止了鞋的大量的轴向和周向移动,同时当有效负载与壳体分离时允许翼和导靴的向外运动。 在这种分离期间,导靴也与翼分离,使得后者可以枢转到最大程度,以在有效载荷上提供最佳的旋转制动作用。
