Abstract (en)
[origin: WO8605581A1] The propulsion means (1) for reducing the base drag of a projectile (12) is comprised of a central ignition channel (4) and an ignition device (16). In order to improve the ignition facility of the propulsion means (1) the surface (1a) delimiting the central channel (4) presents a conical shape which becomes narrower towards the rear portion. Furthermore, the surface (1a) presents steps (1b). The housing (16a) of the ignition device (16) is provided with ignition channels (16b) which are inclined with respect to the longitudinal axis (100).

Le moyen de propulsion (1) pour réduire la trainée de culot d'un engin ballistique (12) est constitué d'un canal central d'allumage (4) et d'un dispositif d'allumage (16). Afin d'améliorer la susceptibilité d'allumage du moyen de propulsion (1) la surface (1a) délimitant le canal central (4) présente une forme conique se resserrant vers l'arrière. En outre, la surface (1) présente des gradins (1b). Enfin, la boîte (16a) du dispositif d'allumage (16) est pourvue de canaux d'allumage (16b) disposés de façon inclinée par rapport à l'axe longitudinal (100).
