这是一个很普通的工程问题,在爆炸前关掉发动机,发动机就不会爆炸了。 SpaceX的发动机都是为了复用设计的,本来设计就特别结实和鲁棒,同时也装了很多即时监控传感器。飞行过程中,火箭系统以毫秒级间隙密度监控发动机,有问题的发动机会被自动关闭,根本就走不到爆炸那一步。 传统的火箭因为没有冗余设计,失去任何一个发动机都意味着失败,所以既没有关机设计也没有那么高密度的监控,发动机即使状态不好也只能硬顶,能够顶到工作时间完成就成功,顶不住就爆炸

说的好像很有道理,可是去年年底starship第二次发射推进器不是因为一个发动机出故障爆炸了!?还根本走不到爆炸那一步?不是事实摆在那里,我都信你说的了。
Following stage separation, and as the booster began its descent stage, “several engines began shutting down before one engine failed energetically,” resulting in a chain of events that ultimately resulted in the destruction of the Super Heavy, the company explained. SpaceX identified filter blockage as the culprit, in which oxygen-rich liquid from the engines clogged the filters. This led to the shutdown of several engines and an explosion about three and a half minutes into the flight, while Starship was flying 56 miles (90 kilometers) over the Gulf of Mexico. SpaceX claims to have already implemented a fix.
