Abstract: The technical field of the invention relates to devices providing for the ejection of a plurality of payload elements from the casing of a carrier shell. The ejection device according to the invention includes a pyrotechnic composition placed in a head and intended to create, after ignition, a gas pressure that pushes a piston over a short distance so as to displace towards a base a moving assemblage having a pusher plate and payload elements, and to eject the base, the piston then being stopped relative to the head and having an orifice which allows the gases to pass towards the moving assemblage so as to push the latter. The device includes braking means disposed between at least a part of the moving assemblage and the shell casing. This invention is applicable to mine-dispersing carrier shells.

Abstract: The technical field of the invention is that of carrier artillery shells. The carrier shell according to the invention is intended to transport at least one payload and contains a casing on which is placed at least one spinner band, the casing being closed at one of its ends by a base and at the other by a head inside of which is placed a gas-generating pyrotechnic composition intended to act on a piston at the time the payload is ejected; the shell being characterized in that the means by which the payload is spun by the casing includes lugs provided on an extension of the head and which interact with notches provided on an upper face of the piston, as well as means to cause the piston and the payload itself to spin together. This invention is applicable to mine-dispersing shells.
