The present invention relates in general to a recoilless weapon (1) and, in particular to a new high- and low pressure system for recoilless weapons (1). The invention provides a recoilless weapon (1) comprising a launch tube (2) open at muzzle (3) and breech (4) ends thereof, a projectile (5) and a counter mass (6) residing in said recoilless weapon (1), the recoilless weapon (1) further comprises a high pressure part (7) containing a propellant charge (8) for propelling the projectile (5) and the counter mass (6) out of the launch system (1), a low pressure part (9) containing the counter mass (6), a blocking element (16) in the rear part of the launch tube (2) and gas-openings (10) between the high pressure part (7) and the low pressure part (9) The invention is characterized in that the projectile (5) is positioned in a first start position, where the projectile (5) is blocking the gas-openings (10) and where the projectile (5), upon ignition of the propellant charge (8), moves to further positions (12′) in the launch tube (2), where the gas-openings, successively, are unblocked by the projectile (5). |
