Abstract
Electro-magnetic decoy-launcher ammunition has an external housing, which houses an impeller in its lower section and encloses a charge of electro-magnetic decoy material which can be ejected by a thrust device when the impeller is excited. The charge remains in its tubular transfer container, and the thrust device is mounted within the transfer container and comprises a semi-rigid disc actuated by a piston, fitted with a peripheral projection, which defines with the disc an annular housing for a split ring for taking up play and a felt washer ensuring that the device is fireproof.
Claims5
Electro-magnetic decoy-launcher ammunition, comprising an outer body having a lower portion, impeller means in said lower portion of said body, thrust means, a charge of electro-magnetic decoy enclosed in said body to be ejected by said thrust means when the impeller means is excited, means defining a tubular transfer container in which the charge remains inside the outer body, said tubular transfer container being closely fitted into said outer body, said transfer container having a bottom portion, said thrust means comprising a thrust piston in said bottom portion of the transfer container, said thrust piston including means defining an internal downwardly directed recess, peripheral sealing means for providing a seal against the inner surface of the transfer container, a top defining a plane surface, and a semi-rigid disc co-operating with the plane surface of the thrust piston and in contact with the charge on its other side, said impeller means being disposed to cause the propelling agent to co-operate with the internal recess of the thrust piston.
