回复:喷射式火箭的动力来源跟大气密度到底有啥关系?

你都说了喷射(气)式了,你觉得还跟空气密度没有关吗?
解释交给 openAI:

Yes, if the air pressure is thinner, a rocket would generally require more fuel to achieve the same level of thrust and acceleration.

The thrust produced by a rocket engine depends on the principle of action and reaction. The engine expels high-speed exhaust gases in one direction, and as a result, the rocket experiences an equal and opposite force pushing it forward. The density of the surrounding air affects this process.

When a rocket is launched, it pushes against the air molecules in its path. If the air pressure is higher (thicker air), there are more air molecules to interact with, resulting in increased resistance or drag. This increased drag can hinder the rocket's acceleration.

In contrast, if the air pressure is lower (thinner air), there are fewer air molecules for the rocket to push against, reducing the drag. While this may seem advantageous, it also means that there are fewer molecules available for the rocket to gather oxygen from to support combustion in the engines.

To compensate for the reduced air density, a rocket may require more fuel to maintain its desired thrust level. The additional fuel helps to ensure an adequate supply of oxidizer (e.g., liquid oxygen) for combustion, compensating for the reduced availability of oxygen in the thinner air.
