摘要:
为使常规火炮发射1 kg弹丸的炮口速度在2 000 m/s以上,该文提出一种浮动串联双药室火炮发射技术。分析了该发射技术的工作原理和发射过程的4个不同阶段,建立了发射过程的经典内弹道模型,并进行了数值模拟,求解出采用该技术发射时各弹道参数的压力-时间和速度-时间变化规律,分析了双药室装药种类和装药量、药室间的破孔压力、弹丸启动压力对弹丸炮口速度的影响。研究结果表明,当第二药室装1.2 kg 5/7火药、药室间的破孔压力为100 MPa、弹丸的启动压力为180 MPa时,弹丸获得最大炮口速度2 547 m/s。
Abstract:
To make the muzzle velocity of 1 kg projectile shot by a conventional cannon be above 2 000 m/s,a shooting technology with two floating tandem chambers is proposed.The operational principle and the four different stages of the shooting technology are analysed.This paper gives the interior ballistics equations of the various stages,solves the changing laws of projectile’s moving and the in-bore pressure distribution by applying the technique,for example,the law of press-time and the law of velocity-time.Several major factors influencing the muzzle velocity of projectiles are analysed,concerning the powder variety and weight of first chamber and second chamber,the diaphragm rupture pressure of two floating tandem chambers and the projectile shot-start pressure.It is concluded that the maximal muzzle velocity of projectiles can reach 2 547 m/s when the second chamber has 1.2 kg 5/7 powder,the diaphragm rupture pressure of two floating tandem chambers is 100 MPa and the projectile shot-start pressure is 180 MPa.
