Abstract

TITRE : MUNITION TELESCOPEE COMPRENANT UN PROJECTILE SOUS-CALIBRE STABILISE PAR UN EMPENNAGE DEPLOYABLE L’invention concerne une munition (1) de type télescopée, comprenant un étui (2) à l’intérieur duquel sont logés un projectile sous-calibré (16) équipé d’un sabot (11) éjectable segmenté, un chargement propulsif (8) et un dispositif d’allumage (4) du chargement propulsif, caractérisée en ce que ledit projectile sous-calibré (16) comporte un prolongement (10) recevant un empennage (19) mobile entre une position repliée contre ledit prolongement et une position déployée, ledit sabot (11) maintenant ledit empennage (19) dans ladite position repliée, ledit sabot (11) enveloppant ledit empennage (19) pour l’isoler afin d’empêcher le contact entre ledit empennage (19) et ledit chargement propulsif (8). FIG. 1TITLE: TELESCOPED AMMUNITION COMPRISING A SUB-CALIBER PROJECTILE STABILIZED BY A DEPLOYABLE TAILPIECE of a segmented ejectable sabot (11), a propellant charge (8) and an ignition device (4) for the propellant charge, characterized in that the said sub-caliber projectile (16) comprises an extension (10) receiving an empennage (19) movable between a folded position against said extension and a deployed position, said shoe (11) maintaining said empennage (19) in said folded position, said shoe (11) enveloping said empennage (19) to isolate it in order to prevent contact between said empennage (19) and said propellant charge (8).
