摘要
提出采用传统火炮发射与基于火箭喷射原理相结合的组合发射工作模式,采用修正的Lagrange假定,建立了相关的内弹道理论模型。通过数值求解和多方案对比优化,得出组合发射方案,在最大膛压、弹丸行程等不变的条件下,取随行率约30.5%,弹丸初速可提高9.4%,炮口动能增加19.7%。但最大弹底压力与最大膛底压力之比由无随行的0.67提高到0.97。
A firing work pattern combined with traditional gun launching and rocket spraying theory was presented for some artillery. The interior ballistic theoretical model was established by modified Lagrange assumption. The optimizing combined firing scheme was obtained through numerical calculation and comparing multi-schemes. Based on the invariable maximum bore pressure and projectile travel, adopting ration of traveling charge as by 30.5%, the initial velocity of projectile can be increased by 9.4% and the kinetic energy nearby the gun muzzle can be increased by 19.7% in this scheme. The ratio of maximum projectile base pressure to chamber base pressure was increased from 0.67 to 0.97.
