Abstract:
This study presents a theoretical concept design analysis and verification of the new automatic weapon transmission mechanism based and improved on the Italy BELLINI shotgun transmission mechanism. An inertia-driven system is used in the Italian BELLINI shotgun to transmit the recoil energy generated by propellant burning and a high-pressure gas to make the shotgun fire semi-automatically. This study combined the principle of this inertia-driven system with that of a barrel short recoil-operated system to create a new type of transmission mechanism for an automatic weapon to transfer the recoil energy and shoot full-automatically. In this study, computer-aided design, mechanism simulation, and the analysis software ADAMS (Automatic Dynamic Analysis of Mechanical System) were used to design and analyze the new type of transmission mechanism to observe the movement of the new mechanism in the simulation and analyze the performance parameters of its action. Finally, the feasibility of the new transmission mechanism theory for automatic weapons was verified by shooting a sniper gun acting with barrel short recoil fully automatically.
