    摘要: A base bleed unit arranged to increase the range of fire or to reduce the time of flight for shells and projectiles includes a housing (1) surrounding a fuel charge (6) and associated igniter (4), extending from the rear portion of a projectile body (2) and including at least one outlet nozzle (5, 5ʹ, 5ʺ) for combustion gases, which by means of a mass flow, and possibly combustion adjacent to the base plane, reduce existing base drag. According to an embodiment of the invention, the housing (1) comprises a caseshaped member 1 attachable against a projectile body (2), having at least one igniter (4) arranged adjacent to an internal plane of a restricting wall surface at the housing (1), located in an opposed relationship to the portion of the housing (1) attachable against a projectile body (2). The combustion flame of the igniter (4) is hereby maintained directed towards the fuel charge (6) and away from the outlet nozzle/nozzles (5, 5ʹ, 5ʺ). Advantageously, a number of outlet nozzles (5, 5ʹ, 5ʺ) are used, arranged spaced in an annular relationship to each other, and preferably inclined towards the outer peripheral portion of the restricting wall surface. A number of igniters (4) are advantageously used, located in recesses or blind holes taken up by the inside plane of the restricting wall surface. It is further advantageous to arrange the open portion of each igniter (4) partly covered by a covering means, thus accomplishing a reduced outlet area. According to a second embodiment, the housing (1) may also be formed by attachment of a bottom member to a projectile body (2) having a rearwardly open projectile extension, said bottom member including one or a number of igniters (4).

    摘要: Um die Anzündempfindlichkeit eines Treibsatzes zur Boden­sogreduzierung eines Artilleriegeschosses zu verbessern und eine sichere und sofortige Anzündung unmittelbar nach dem Rohraustritt des Geschosses auch bei geringen Rohr­durchlaufzeiten und hohen Mündungsgeschwindigkeiten zu ge­währleisten, erhält die den Zündkanal 4 begrenzende Wand 5 oder eine kanalseitig angeordnete anzündverstärkende Schicht 2 des Treibsatzes 1 eine oberflächenvergrößernd aufgerauhte Struktur. Dadurch wird im Wandbereich des Zündkanals 4 trotz hoher Sogwirkung eine sichere und so­fortige Anzündung des Treibsatzes 1 unmittelbar nach dem Rohraustritt des Geschosses erzielt. Die Struktur der oberflächenvergrößernden Aufrauhung kann unterschied­lich sein und besteht beispielsweise in einer nicht dar­gestellten Art aus Querrillen, Noppen oder Poren. Die Tiefe der aufgerauhten Schicht liegt bevorzugt in einem Bereich zwischen 1 mm und 3 mm. Beim Einsatz eine anzünd­verstärkenden Schicht 2, beispielsweise einem pyrotechni­schen Belag, kann ggfs. die Anzündeinrichtung 16 entfallen.
