摘要

实现高初速条件下的高精度发射性能是电磁轨道发射技术的重要研究课题，为了实现这些目标，相比于常规火炮发射过程，需要针对全新的科学问题开展研究，其中包括：1）电枢挤进过程中初始接触的均匀一致性；2）内弹道一致性；3）膛内发射动力学；4）伴随电弧磁流体的膛口脱壳动力学；5）超高速飞行一致性；6）脉冲放电一致性。从弹道学角度开展理论及实验研究，涵盖了包括起始弹道、内弹道、中间弹道、外弹道在内的整个发射过程。基于相关理论及关键技术，设计了小口径电磁轨道炮发射系统，配备了一体化射弹及高重复频率高精度脉冲电源系统。开展了电磁轨道炮发射实验，实现了高精度发射性能。实验结果表明，发射初速超过2000m/s，发射系统具备良好一致性，炮口初速误差小于5‰。

Abstract

Achievingthehigh muzzle velocity and high precision in launching process is an important research subject for electromagnetic railgun

a direct-fire weapon.Thelaunch processoflaunch processis differentfrom that ofconventional artillery. Therefore

some completely new scientific issues need to be investigated to achieve the esearch objective

including 1)the uniformity and consistency of initial contact between the armature and the rail during the engraving process of armature loading; 2)the interior ballistics consistency; 3)the in-bore launch dynamics; 4)the discarding sabot dynamics of muzzle with arc magnetic fluid; 5)the flight of hypervelocity projectile;and6)the consistency of pulsedischrage. This paper carries out theoretical and experimental research from the perspective of ballistics

covering the entire launching process

including initial ballistics

internal ballistics

intermediate ballistics

andexternal ballistics.Asmall-caliber electromagnetic railgun launch systemis designedbased on relevant theories and key technologies

which isequipped with an automatic loading system

a high repetition rateandhigh-precision pulsed power supply system

and an integrated launch package (ILP). The electromagnetic railgun launch experimentsareconducted

and the high-precision launch performanceis realized. The experimental results demonstrate that the muzzle velocity exceeds 2000m/s

the launch systemhasgood consistency

and the muzzle velocity error is less than 5‰.
