  • Patent number: 4756253
    Abstract: 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.
