Since 2016, Hanwha Defense Corporation has been working on applying electromagnetic launch technologies such as induction coilguns to cold-launch systems that can launch guided missiles. First, a design procedure of a multistage coilgun system based on the pulsed power driven by capacitor banks was developed using the Taguchi method, and a laboratory-scale three-stage coilgun capable of launching a 21.68-kg projectile at a maximum speed of 27.5 m/s was built and the results of the experiment were announced in 2018. In this article, we design, fabricate, and present the experimental results of a pulsed power-based four-stage induction coilgun using the proposed procedure to prove the validity of the electromagnetic launch technology for heavy missile launch. In this experiment, a 100-kg projectile was fired under 4-kV charging conditions, the maximum speed of the projectile was 25 m/s or more, and an efficiency of 15% was achieved without considering the mass of the armature. In this study, by accelerating a 100-kg projectile to 27 m/s, the feasibility of an electromagnetic launcher developed for heavy missile launch was verified.

用于发射重型弹丸的脉冲功率四级感应线圈炮的设计、制造和实验结果


自2016年以来，韩华防务公司一直致力于将感应线圈炮等电磁发射技术应用于可发射制导导弹的冷发射系统。首先，使用田口方法开发了基于电容器组驱动的脉冲功率的多级线圈炮系统的设计程序，并开发了能够以27.5 m的最大速度发射21.68 kg弹丸的实验室规模的三级线圈炮。 /s 建成并于 2018 年公布了实验结果。在本文中，我们使用所提出的程序设计、制造并展示了基于脉冲功率的四级感应线圈枪的实验结果，以证明该方法的有效性用于重型导弹发射的电磁发射技术。本实验中，在4 kV充电条件下发射100 kg弹丸，弹丸最大速度为25 m/s或更高，在不考虑电枢质量的情况下，实现了15%的效率。在这项研究中，通过将100公斤弹丸加速到27 m/s，验证了为重型导弹发射而开发的电磁发射装置的可行性。
