| 摘 要： | 载人飞船主要通过火箭的助推将飞船送入太空。事实证明,飞船升空一定要用多级火箭才行,那么到底要用多少级火箭发射才适宜呢?文中以Maple为工具,建立了火箭发射载人飞船的加速度模型,给出了计算各级火箭助推产生的末速公式,并合理解释了需要使用三级火箭发射载人飞船的道理。

| Abstract: | Manned spaceship was launched to space mainly by the propelling of rockets.It proves that the launching of spaceship must be propelled by layers of rockets,but how many layers are needed?This paper,based on Maple,discusses the establishment of acceleration mode of rocket-launched manned spaceship,provides the formula of the last speed for calculating the propelling of layers of rockets,and reasonably explains the necessity of applying three layers of rockets to propelling manned spaceship. |
