摘要
为满足现代战争需要,大幅度提高火炮初速至关重要。提出了一种基于电磁线圈发射的火炮增速技术,弹丸火药发射过程中,该增速技术通过电磁线圈发射装置在弹丸薄壁上产生电磁力,进一步推动弹丸加速,从而达到增速效果。基于电磁线圈发射的场路耦合有限元模型,分别对不同身管材料的磁阻型线圈发射和同步感应型线圈发射进行分析,并研究身管厚度对发射性能的影响,结果表明逆磁性绝缘身管的同步感应型线圈发射性能最佳,且身管越薄,发射性能越好。最后对25级线圈发射器的增速性能进行估算,结果显示可将原出膛速度为600 m/s的弹丸加速到757.19 m/s,增速率为26.2%。分析表明基于电磁线圈发射的火炮增速技术可以极大地提高火炮初速,具有广阔的应用前景。
In order to meet the needs of modern war,it is very important to greatly increase the muzzle velocity of artillery.A gun acceleration technology based on electromagnetic coil launching is proposed.In the process of firing projectiles by power guns,the acceleration technology generates an electromagnetic force on the thin wall of the projectile through the electromagnetic coil launcher to further promote the velocity of the projectile so as to achieve the acceleration effect.Based on the field circuit coupling finite element model of electromagnetic coil launch,this paper analyzes reluctance coil launch and synchronous induction coil launch of different barrel materials,and studies the influence of barrel thickness on launch performance.Results show that synchronous induction coils in a diamagnetic insulated barrel have the best launch performance.The thinner the barrel,the better the launch perfor-mance.Finally,the acceleration performance of a 25 stage coil launcher is estimated.Results show that the projectile with the original exit velocity of 600 m/s can be accelerated to 757.19 m/s,and the[JP3]acceleration rate is 26.2%.Analysis shows that the gun acceleration technology based on electromagnetic coil launching can greatly improve the muzzle velocity of the gun,and has broad application prospects.[JP]
