摘要
在"T"字型双边直线电机原型推进器的基础上,提出感应电磁推进器初级绕组电磁"U"字型结构,并分别采用串联和并联的供电方式为驱动线圈供电;由于双边型推进器属于开放式,漏磁较大,因此在双边型的基础上加以改进,提出"U"字型半封闭式推进器模型;在保持励磁线圈材料、感应线圈材料与质量不变的前提下,研究了感应线圈形状以及其供电方式与电磁推进器的推进速度、推进效率、推进稳定性等性能指标的关系;分析结果表明:"U"字型推进器发射性能整体优于"T"字型推进器;串联供电方式优于并联方式。
Learn from the T type double-sided linear induction propeller,a new type drive coil structure of induction electromagnetic propeller was proposed.It was U type linear induction propeller.Power was supplied to the drive coil in tandem and in parallel respectively.The U type semi-closed electromagnetic propeller was proposed due to the large magnetic leakage and the openness of the T type linear electromagnetic propeller.The relationship between the shape of the drive coil,the mode of the power supply and the muzzle velocity,the efficiency,the stability of the electromagnetic propeller have been researched.The result indicates that the propelling property of the U-shaped is better than the T’s and the tandem power supply mode is better than the parallel’s.
