Abstract:
An airborne dropping device for distributing interference medium including electronic raspberry and interference medium having an infrared (IR) signature, the dropping device comprising:a magazine having a feed-out opening directed rearwards with respect to a motional direction of the dropping device, wherein a plurality of packs of the interference medium are arranged sequentially within the magazine; and a feed device comprising rotary members which, on receipt of a feed command, stepwise feeds each of the plurality of packs of interference medium towards the feed-out opening, said rotary members each including a camshaft, wherein a number of stop positions of the camshaft is equal to a number of cams on the camshaft, wherein, when the camshaft is in one of the stop positions, a radial outer periphery of one of the cams acts as a stop for feed-out of a next interference medium pack, wherein, when the camshaft is in motion, a front flank of said one of the cams, in a motional direction of the camshaft, acts both as a separation member between successive interference medium packs and as an acceleration member for a front interference medium pack when the front interference medium pack leaves the feed-out opening, wherein each camshaft is arranged parallel-driven along at least two opposite side edges of the feed-out opening, wherein the camshaft included in each of the rotary members is mechanically coupled at least through an intermediate gear unit to a belt-driven gear train, said mechanical coupling preventing an uncontrolled exit of the next interference medium pack from the feed-out opening when a belt in the belt-driven gear train is broken, and wherein a motion of each of the camshafts is stepped up by a number of whole multiples relative to the motion of the feed device.
