Recoilless firearm launch tube - has breech with propulsive and aerodynamic braking systems working in succession

摘要

The recoil-less firearm has a launching tube (4), open at each and for a projectile (1) and has a moving breech (3). A propulsion charge (2) is placed between the projectile and breech. The breech has a braking and propulsion assembly (5). The breech has an aerodynamic brake (6) actuated after the firing and propulsion braking phases. The aerodynamic brake consists of fins, pivoted on the front of the breech. It can also include a fabric parachute fixed to the fins. The brake is held by inertia and later released.
