带一组助推火箭的三级火箭(或航天飞机),当这种并(串)联型多级火箭的各级有效喷速依次递增时,求出了其最大速度值的变化规律;此时最大速度方案等一系列问题也被同时解决了。最后指出了串联型多级火箭和并(串)联型多级火箭的一个重要不同点。
The three-stage rocket (or space shuttle) with a group of boosting rockets obtains the variation law of the maximum velocity value when the effective jet velocity at all levels of the parallel (serial) When the maximum speed program and a series of other problems have also been solved. Finally, it points out an important difference between tandem multi-stage rockets and parallel (tandem) multi-stage rockets.
