    • Apparatus is disclosed which provides for the controlled deployment of a flexible samara blade used to orient and decelerate a submunition cannister which is dispensed at altitude and allowed to free fall to earth. Spin pins are anchored in and extend outwardly from the downstream end of the cannister. Placement of the pins is such that the flexible samara blade can be wrapped around the pins to place the blade in a stowed condition within the periphery of the cannister end prior to launch of the submunition. Caps on the pins are used to inhibit the stowed blade from slipping off the pins. The blade is wrapped around the pins in a direction opposite to the direction of rotation of the submunition during launch. Launching the submunition in a spinning state creates a centrifugal force in the weighted tip of the samara blade causing the wing to unwrap from the stowed to the deployed state. The pins keep tension in the unfolding wing and preclude erroneous twist-up of the flexible blade.
    • 公开了一种设备,用于控制部署用于定向和减速子弹药罐的柔性samara刀片,所述子弹药罐在高度被分配并被允许自由落体。 旋转销被锚固并从罐的下游端向外延伸。 销的放置使得柔性samara刀片可以缠绕在销上,以在发射子弹药之前将刀片放置在罐末端的周边内的收纳状态。 引脚上的盖子用于禁止收起的刀片从引脚上滑落。 在发射期间,刀片沿着与子弹药旋转方向相反的方向缠绕在销上。 在旋转状态下启动子弹药在萨马拉叶片的加重尖端产生离心力,导致机翼从收起的展开状态展开。 针脚在展开的机翼中保持张力,并防止柔性叶片的错误扭曲。

    • A submunition having an infrared detector disposed in a nose portion thereof, the detector having a narrow angularly-displaced field of view, and vanes for causing the submunition to rotate at an essentially constant rate while in flight, thus to cause the infrared detector to scan a target area and to detect the presence of a target having a selected higher temperature than the background infrared radiation. The submunition includes a small explosive charge sheet disposed on its outer surface and concentrated in one area, and firing pulse generation means for firing the charge. When the infrared detector scans past a detectable target within the target area, it produces a detection signal that triggers a firing pulse from the firing pulse generation means, thereby firing the explosive charge to create a lateral impulse or offset of the submunition. Timing means is provided to cause the impulse to be produced in the exact direction to correct the terminal trajectory of the submunition to intercept the detected target, so that the warhead carried by the submunition can cripple or destroy the target. This novel correctable-trajectory submunition is therefore seen to be a low-cost device having high kill probability when air-dropped in clusters, thereby providing very high cost effectiveness.

    • A control system for an ammunition having a longitudinal axis and adapted to move in a flight direction, particularly a wingless ammunition falling in ballistic flight, comprises a body having a rear curved surface with a gas generator in the body for producing gas under pressure. A nozzle is mounted to the body and oriented to direct a gas jet produced from the pressurized gas rearwardly and tangentially over the curved surface with respect to the flight direction of the ammunition. The gas jet produces reduced pressure on its side of the ammunition to alter the flight thereof.

    • An air dispensed assembly in the form of a submunition cannister is disclosed which has the capability to perform a lateral maneuver during the final 1500 ft. of descent before impact. Maneuvering is accomplished by deploying a samara blade shaped wing from the rear of the submunition cannister after ejection from the casing of the launching shell. The wing is sized and provided with an angle of attack which causes the cylindrical shaped cannister to spin as it descends downward at approximately a constant rate of descent. A passive infrared sensor in the nose of the cannister provides target information to a data processor which generates steering commands to appropriately alter the wing angle of attack so as to bring about a corrective lateral change in direction. When within lethal range of the sensed target, the warhead in the submunition is detonated.
