以带一组助推火箭的三级火箭为例,详细讨论了喷气速度递增时此多级火箭何时才是加满最好,以及加满不是最好时最好点在哪里,由此完善了多级火箭的最大速度问题的理论。
Taking a group of three-stage rockets with booster rocket as an example, we will discuss in detail when the multi-stage rocket will fill up the best when the jet speed increases and where is the best point when filling up is not the best The theory of multi-stage rocket’s maximum speed problem.
