摘要： A weapon arranged to travel in a given orientation when in flight, has a body and a ribbon. The body has a payload casing and a spindle rotatably mounted at the rear of the payload casing. The ribbon is formed into a flexible loop for trailing behind the body in flight. This ribbon is attached to the spindle. The ribbon has an impelling surface shaped to apply a torque to the spindle when in flight.

摘要： A grenade device for use with and for ejection from an artillery shell is ovided. The device includes a stabilizing propeller and a grenade body. The propeller has two opposite blades disposed on opposite sides of a rotation axis. Each blade has an upper tilted portion and a lower substantially flat portion and a connecting return bend tip portion. Each such portion has a leading edge and a trailing edge. Each upper tilted portion has a transverse angle of attack. The upper tilted portions have a common longitudinal upper projected axis. The lower flat portions also have a common longitudinal lower projected axis. The common longitudinal upper projected axis and the common longitudinal lower projected axis form a projected displacement angle therebetween. The propeller is made from a flexible metal or fabric ribbon. The blades are folded in a nested arrangement before descent. During descent, the blades unfold to their overall aerodynamic shape. The propeller has a windmill type of rotation during descent. The grenade body may have an alternator as part of an electronic fuze, which is connected to a shaft, that is connected to the propeller coaxially therewith along the rotation axis for energizing the alternator.
摘要翻译： 提供了用于与炮弹弹出并用于从炮弹弹出的手榴弹装置。 该装置包括稳定螺旋桨和手榴弹体。 螺旋桨具有设置在旋转轴线的相对侧上的两个相对的叶片。 每个叶片具有上倾斜部分和下基本上平坦的部分以及连接的返回弯曲末端部分。 每个这样的部分具有前缘和后缘。 每个上倾斜部分具有横向迎角。 上倾斜部分具有共同的纵向上部突出轴线。 下部平坦部分也具有共同的纵向下部突出轴线。 共同的纵向上部突出轴线和公共纵向下部突出轴线在其间形成投影位移角。 螺旋桨由柔性金属或织物带制成。 叶片在下降之前以嵌套的方式折叠。 在下降期间，叶片展开至其整体空气动力学形状。 螺旋桨在下降期间具有风车类型的旋转。 手榴弹体可以具有作为电子引线的一部分的交流发电机，该电子引信连接到轴，其沿着旋转轴线与其同轴地连接到推进器，以激励交流发电机。

摘要： A flexible wing which is connected to a submunition provides a substantia vertical descent and provides torque which power submunition electronics. The flexible wing is deployed in a low drag configuration to avoid collision with other submunitions. The flexible wing is canted to allow rotation of the wing.
