导弹电磁发射技术使用电能代替化学能作为发射能源,是一种对导弹及导弹发射技术具有革命性影响的新概念发射技术。以提高效率和功率密度为目标,提出了一种基于磁通切换永磁直线电机的导弹电磁发射技术方案。该方案兼具感应直线电机动子结构简单坚固和永磁直线电机功率密度高的优点,适合高速运行且易于模块化扩展。直线电机选择双边绕组磁路串联结构以降低了次级动子的质量,高功率脉冲电源使用电容储能并采用多逆变器并联方案。原理样机试验结果表明:该方案在最大运行速度和最高工作频率下速度控制快速、平稳,制动过程安全可靠。
The use of electric energy instead of chemical energy as the launch energy for missile electromagnetic launch technology is a new concept launch technology that has a revolutionary impact on missile and missile launch technologies. In order to improve the efficiency and power density as the goal, a magnetic flux switching based on permanent magnet linear motor missile electromagnetic emission technology program. The scheme has the advantages of simple and strong mover structure of induction linear motor and high power density of permanent magnet linear motor, which is suitable for high-speed operation and is easy to modularized and expanded. Linear motor selection of bilateral winding magnetic series structure to reduce the quality of the second mover, high-power pulse power storage capacitor and the use of multi-inverter parallel program. The prototype test results show that: the program in the maximum operating speed and maximum operating frequency speed control fast, stable, safe and reliable braking process.
