Abstract
A contained Davis gun system enables misfire and hang-fire handling for fire out of battery (also known as soft recoil). The gun system decreases structural dynamic activity of the gun barrel during launch with resulting increases in system accuracy. The gun system further presents synergistic advantages when combined with a conventional recoil system in a double recoil design. The gun system includes a non-recoiling barrel and a recoil system engineered to contain a recoiling inertial breechblock capable of translating within the gun barrel. The recoil system includes a brake and a spring secured to a mount fixture. The breechblock enables the loading of the propellant and the projectile within the barrel, and further enables pressure to be contained within the barrel during firing. The recoil system applies a load to the breechblock, which is a function of the breechblock position and its velocity within the barrel. A part of the kinetic energy imparted to the breechblock is stored as potential energy within the spring, and the remaining kinetic energy is dissipated by the brake as heat. Prior to firing, the barrel and the recoil system are coupled to the firing platform. When th…
