Abstract

Eine Beschleunigungsvorrichtung (10) zum Beschleunigen eines Projektils (16) weist ein Beschleunigungsrohr (12) mit einer eine Beschleunigungsrichtung (14) definierenden Längsachse und einen Treibspiegel (18) mit einer Projektilaufnahme (32) an seinem in der Beschleunigungsrichtung (14) vorderen Ende zum Aufnehmen eines Projektils (16) auf. Das Beschleunigungsrohr (12) weist in seinem in der Beschleunigungsrichtung vorderen Endbereich einen Treibspiegelstopper (30) zum Aufhalten des Treibspiegels (18) auf und ist an seinem in der Beschleunigungsrichtung hinteren Ende mit einer Druckerzeugungsvorrichtung (34) gekoppelt. Zum Erzielen höherer und besser reproduzierbarer Projektilgeschwindigkeiten weist die Druckerzeugungsvorrichtung (34) wenigstens zwei Ventile (50) zum Einleiten eines Gases in eine Treibkammer (54), welche in dem Beschleunigungsrohr (12) in Beschleunigungsrichtung hinter dem Treibspiegel (18) gebildet ist, auf.

Figure imgaf001
An acceleration device (10) for accelerating a projectile (16) has an acceleration tube (12) with a longitudinal axis defining an acceleration direction (14) and a sabot (18) with a projectile receptacle (32) at its front end in the direction of acceleration (14) Picking up a projectile (16). The accelerator tube (12) has a sabot stopper (30) for arresting the sabot (18) in its forward end portion in the acceleration direction, and is coupled to a pressure generating device (34) at its rear end in the accelerating direction. To achieve higher and more reproducible projectile speeds, the pressure generating device (34) has at least two valves (50) for introducing a gas into a drive chamber (54) formed in the acceleration tube (12) in the direction of acceleration behind the sabot (18).
