Patent

CA 2415089

The present invention relates to a method and an arrangement for shells (1a, 1b) fired from launch weaponry, using some of the barrel pressure built up in the barrel during the launch phase for an additional active function over and above that of giving the shell (1a, 1b) in question its trajectory velocity. According to the invention, during the launch phase, some of the propellant powder gas accelerating the shell is therefore introduced into a chamber (12, 38, 60) which is arranged in the same and which is delimited in at least one direction by an element (8, 31, 58, 52, 53) which is movable relative to the rest of the shell and on which the barrel pressure acting on the shell simultaneously acts to maintain the original direction as long as the shell is located inside the barrel during the launch phase. This technique can thus be used to remove protective casings covering the fins, in order to push out fin units and to deploy initially retracted fins.

L'invention concerne un procédé et un arrangement destinés à des munitions (1a, 1b) tirées depuis un armement de tir, utilisant une partie de la pression créée dans la chambre lors de la phase de tir pour une fonction active supplémentaire autre que celle donnant à la munition (1a, 1b) en question sa vitesse de trajectoire. Selon l'invention, durant la phase de tir une partie du gaz de poudre propulsive accélérant la munition est donc introduite dans une enceinte (12, 38, 60) disposée dans la munition et délimitée, dans au moins une direction, par un élément (8, 31, 58, 52, 53) mobile par rapport au reste de la munition et sur lequel la pression régnant dans la chambre, agissant sur la munition, agit de manière simultanée afin de maintenir la direction originale aussi longtemps que la munition reste à l'intérieur de la chambre lors du tir. Cette technique peut ainsi être utilisée afin d'éliminer des protections placées sur les dérives, de façon à pousser puis à déployer les unités de dérive initialement rétractées.
