针对如何提高地空导弹初始发射速度和战场隐蔽性的问题,设计了一种新型地空导弹多极矩电磁发射器。多极矩电磁发射器的结构装置为弹射线圈产生电磁弹射力,多极矩线圈来产生持续轴向加速力,以单级六极矩线圈为例,采用电磁场有限元方法进行发射过程仿真并提出了该发射器的设计流程。以某型地空导弹的发射性能为指标,根据建立的发射器原理和仿真模型计算得出了该发射器的线圈和电路参数,实现了地空导弹多极矩电磁发射器的设计。

In order to improve the initial emission velocity and the battlefield concealment of surface-to-air missile, a new type of muhipole electromagnetic emitter for surface-to-air missile was designed. The structural device of multipole electromagnetic launcher produced elec- tromagnetic ejection force for the ejection coil, and the muhipole coil was used to generate a continuous axial accelerating force. Taking a monopole six polar moment coil as an example, electromagnetic field finite element method was used to simulate the launching process and the design procedure of the launcher was proposed. Taking the emission performance of a certain type of surface-to-air missile as the index, according to the principle of emitter and the simulation model to calculate the coil and the circuit parameters of the emitter, the design of multipole electromagnetic launcher of surface-to-air missile was realized.
