电磁弹射学习笔记
现在这模式有点G2搞军备竞赛的FEEL，航天这块人类开发度还很低，未来景气度延续性确实会比较高。
现在的发射模式主要一次性的燃料发射，能量消耗较大，成本较高。
垂直电磁弹射利用电磁能作为初始动力, 类似于电磁炮, 通过地面建造的巨型垂直电磁轨道/线圈系统, 在极短时间内对搭载卫星的微型火箭(或抛射体)施加巨大的电磁力, 使其加速至高超音速(如2马赫以上)。火箭在飞出电磁加速段后, 再启动自身化学推进系统, 进入预定轨道。发射过程拆分为“电磁推射第一程”+“火箭动力第二程”，实现能量供给方式的变革
电磁弹射成本低，可以循环利用，能够满足快速组网的需求。
马斯克在25年年底在推特上构想了电磁发射的可能性。
拉回到国内，其实电磁这块也有一些商业上的突破
总的来说我觉得，这算是一条β属性目前强度一般，都是有延续性的线。
主要还是目前彻底产业化还是有点远，但是技术还是比较好。
产业链个股
其中上游难度是最高的，西部超导，联创光电最近炒的比较火爆也是这个原因。
后续会比较关注中游的湘电。
湘电这家公司肯定是有点技术的，它的两大特种产品是很牛的，舰船综合电力系统 + 电磁弹射，集合了好几个国家科技进步特等奖和一等奖项目技术。电磁弹射用于航母，两栖攻击舰，电磁炮，弹射导弹，核聚变业务等，并在持续拓展应用范围，半年报中就有路基车载电磁弹射项目，据传已有产品面世。舰船综合电力系统的应用面更广，几乎大部分的特种船舰都会用到。这两项技术在全球都是遥遥领先的。
业绩的话，保守拍3亿，也就是80倍PE，2.6倍PB。好在是国资，不会有大雷。
适合波段式操作
