Design and research of high temperature superconducting maglev new boost system

传统的电磁轨道助推发射技术中,被发射物体往往与导轨直接摩擦,导致高速刨削等一系列问题,严重影响发射装置的使用寿命。针对有效载重100 t、加速度15g、发射初速度300 m/s的发射指标,提出了高温超导磁浮发射方案并进行了理论计算。利用高温超导磁浮对被发射物体进行承载,以超导直线电机进行驱动,同时结合真空管道减小发射阻力,并针对发射过程进行了稳定性分析,从根本上解决了轨道发射中的高速刨削问题。研究结果表明:该真空管道磁浮发射方案针对高载重、高加速系统具有一定的可行性,给未来的电磁发射技术提供了一种新的解决思路。

In the traditional electromagnetic rail boost launch technology,the launched object often rubs directly with the guide rail and there are a series of problems such as"high-speed planing",which seriously affect the service life of the launch device.Aiming at the launch index of 100teffec-tive load,15gacceleration and 300 m/s initial launch velocity,a high temperature superconducting(HTS)vacuum tube magnetic levitation launch scheme was proposed and theoretical calculation was carried out.The HTS magnetic levitation was used to carry the launched object,and the supercon-ducting linear motor was driven.Meanwhile,the vacuum tube was used to reduce the launch resis-tance,and the stability analysis was carried out for the launch process,and thus the problem of high-speed planing in rail launching was fundamentally solved.The research results show that the vacuum pipeline magnetic levitation launch scheme is feasible for the high load and high acceleration system,which may serve as a new solution for the future electromagnetic launch technology.
