Abstract

La présente invention concerne un dispositif de propulsion pour une munition (20) telle qu'une grenade utilisable avec un tube lanceur (60), comprenant une bague porte retard (140) et une douille propulsive (150), caractérisé par le fait que le dispositif de propulsion comprend un module (160) porté par la bague porte retard (140) ou la douille propulsive (150) et en communication fluidique avec une chambre (158) de détente des gaz générés par la charge de propulsion (156), le module (160) comportant des évents (165) d'ouverture réglable permettant de libérer des gaz vers l'extérieur du dispositif de propulsion, entre la surface extérieure du corps (20) de la munition et la surface interne du tube lanceur (60) pour permettre l'expulsion des gaz libérés à l'atmosphère vers l'avant du tube lanceur (60) et ainsi régler la portée de fonctionnement de la munition (20).The present invention relates to a propulsion device for a munition (20) such as a grenade usable with a launcher tube (60), comprising a delay carrier ring (140) and a propellant sleeve (150), characterized in that the propulsion device comprises a module (160) carried by the delay carrier ring (140) or the propellant sleeve (150) and in fluid communication with a chamber (158) for expanding the gases generated by the propulsion charge (156), the module (160) comprising vents (165) with adjustable opening allowing gas to be released to the exterior of the propulsion device, between the exterior surface of the body (20) of the ammunition and the interior surface of the launcher tube (60) to allow the expulsion of gases released to the atmosphere towards the front of the launcher tube (60) and thus adjust the operating range of the ammunition (20).
