Is that a sensor on the nozzle or are you active cooling that 🙃 Also all that... for just 30 pounds of force. Still good though for small drones i belive.

I'd imagine that's a prewarmer/active cooler for the liquid oxygen and engine. The line is pretty big and wrapped in aluminium foil for insulation. if I were to build a rocket engine with 3d printed metal a active cooling setup would be optimal and then taking the oxidiser up in temperature would make the pumping process easier.

小弟,看着你这些项目,我大概猜到你想做什么。如果你最终的目的是可控回收火箭的话,我建议你现在就开始对引擎的control plate进行状态空间的设计,最好在Matlab/simulink里面做到hardware in the loop emulation. 不要满足于单控制量输出的性能,因为飞行过程中的变量只多不少,切相互之间的相关度很大,跟理想模型中,互为独立变量的假设相去甚远。 祝你成功👍

@@lshang882 Lets see,.. 'relatively' low cost, compared to more exotic materials, and looks like you're feeding the fuel through the walls to actively cool it to stay clear of the melt-point. And the exhaust looks very consistent, did you do the thing with the exhaust bell shape, to match atmospheric pressure? Looks like an elegant design with low parts count :)

In this engine, the electric pump is used to precisely control the fuel flow, while the valve adjusts the oxygen flow, both ensuring efficient and stable operation.
