火箭飞行中燃气相对速度的讨论

Discussion on the Relative Velocity of the Burning Gas in the Flying Rocket

举例分析了有关文献中关于火箭飞行原理的问题,其实质论点就是燃气的相对速度是相对于燃气喷出后的火箭,而不是相对于燃气喷出前的火箭.

This paper deals with the issue of the principle of flying rocket in physic books through examples. The essential view is that the relative velocity of the burning gas directs at the rocket after the burning gas has ejected, rather than the rocket before the burning gas has ejected.
