The device (1) has a launching tube (10) intended to receive a projectile (9) and a compressor (3) used to feed a primary container (2) with pressurized gas. The container supplies the gas through a valve (7), and a secondary container (6) is connected to the tube through a fast relaxation unit. The secondary container is powered at fixed pressure, and comprises a set of units e.g. cylindrical body (6a), adapted to modify internal volume (V) of the secondary container before pressurization to obtain a range required for the projectile. |
