| Abstract: | A new scheme of two-stage charge for the secondary propulsion in bore was proposed to in-crease the muzzle velocity of the projectile of large caliber automatic weapons. An interior ballistic model of the scheme was established. The effects of loading factors, such as mass matchings of projec?tiles and charges, delay time and pre-tightening force, on bore pressure and muzzle velocity were shown. |
