关于多级火箭的优化理论(28)

On the Optimization Theory of Step-rockets(28)

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。

According to a three-stage rocket with a group of rocket boosters, a method is raised to evaluate the right time of topping up the rocket when the exhaust gas velocity of every stage increases in order and the optimum point when the topping up isn＇t the best solution. The theory of the maximum speed of step rockets is perfected.
