通过对并联型多级火箭的特征速度表达式的仔细分析,指出了当并联型的多级火箭其载荷减小时,如何重新分配各组的推进剂量以达到原来的速度要求。所以它是火箭载荷减小问题(1)的继续。
Through careful analysis of the characteristic velocity expressions of the parallel multi-stage rocket, it is pointed out how to redistribute the propellant doses of each group to meet the original speed requirements when the parallel multi-stage rocket reduces its load. So it is the continuation of the rocket load reduction problem (1).
