基于再生式液体炮( RLPG)及差动原理,提出了一种提高炮射智能弹药初速的新型随行装药方案,其特点是能在保持射弹过载不变条件下,大幅度提高火炮工作容积利用率和初速。这种装药技术便于与次口径脱壳弹设计技术匹配,设计出高升阻比滑翔弹,从而更有利于提高火炮的射程。导出了差动随行装药火炮内弹道模型。数值计算表明,160 mm口径火炮采用这种新型装药方案,在限定最大膛压为350 MPa、射弹底部最大压力为 p2 m≤318 MPa、飞行弹重为43.4 kg及弹丸行程为7.64 m 的条件下,取随行药量9.2 kg、主装药量13.41 kg,弹丸初速相对常规装药可提高26%,火炮工作容积利用率提高约28%。飞行弹丸采用次口径滑翔弹时,弹径为130 mm,采用修正质点外弹道模型计算得到的火炮最大射程可增大到99 km。

A new charge concept for increasing intelligent ammunition muzzle velocity based on differential traveling charge tech-nology which is able to largely increase gun working volume utilization rate and muzzle velocity within the limits of given projec-tile overload was proposed. With adaption of sub-caliber sabot projectile design technology,this charge technique facilitates the design of high lift-drag ratio gliding projectile,and increases artillery range. A differential traveling principle interior ballistic nu-meric model was established. Assuming traveling charge mass 9. 2 kg and main principal charge mass 13. 41 kg,the calculation of 160 mm gun with the new charge technique demonstrates that the projectile muzzle velocity increases by 26% and gun working volume utilization rate increases by 28%,and under the conditions of maximum bore pressure up to 350 MPa,projectile bottom maximum pressure p2m≤318 MPa,projectile mass 43. 4 kg and travel 7. 64 m. Through calculation with modified particle external trajectory model for 130mm sub-caliber gliding projectile,this charge technique can extend maximum range to 99 km.
