摘　　要：提出一种采用双级装药进行膛内二次发射以提高弹丸初速的新技术,为提高大口径自动武器的初速提供了一条新思路,并建立了双级装药弹膛内二次发射内弹道模型,揭示了装填条件中弹丸质量配比、装药质量配比、延迟时间和预紧力约束等变化时对膛压和初速的影响规律。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 projectiles and charges, delay time and pre-tightening force, on bore pressure and muzzle velocity were shown.
