Abstract
A device for ejecting radar chaff comprising a magazine having a number of tubular cells in which chaff bundles are displaced towards an ejection end of the cell. The displacement of the chaff bundles is obtained by means of a plunger device which is longitudinally movable in each cell. Each plunger device is driven by a wire running from an attachment point on the plunger device to the ejection end, and therefrom to a driving wheel. The wire also drives a knife element. The knife edge of the knife element performs a cutting movement substantially longitudinally of the cell, the cutting movement preferably being rotational and in the opposite direction to the direction of movement of the chaff bundle.
Claims5
A device for ejecting radar chaff comprising an elongate magazine having a number of longitudinal, tubular cells in each of which a bundle of chaff may be displaced by displacement means in the direction of an ejection end of the magazine at which end means are provided for detaching the chaff from said bundle by opening a cover surrounding the bundle, characterized in that said displacement means comprises for each cell a plunger device movable longitudinally in the cell and a wire connected to the plunger device and running therefrom in a loop towards the ejection end and back to a driving means for driving said wire, and in that said means for detaching the chaff comprises a knife element having a knife edge adapted to extend into the moving chaff bundle at said ejection end and to perform a cutting movement directed substantially longitudinally of the cell.
