Thanks, though to be honest, I have no idea what they are. Research time.

Here is the whole thing in single video.

It's not very complicated.
On all chemical engines, there are turbopumps to suck fuel and oxydizer from the tank to send them to the combustion chamber. But those turbopumps require a LOT of power to work. So the solution to provide such power is to use a fraction of the propellants for this.

For this purpose, there's a pre-burner that consumes a part of the propellants, and its exhaust is used to power the turbopumps. Now, what does this exhaust become?

• On an open cycle engine, this exhaust is evacuated through a pipe. Note that this doesn't significantly contribute to thrust, as the gases have to pass through the nozzle to be accelerated. Open cycle engines are easier to design, but less efficient because a part of the combustion energy is lost that way.
• On a closed cycle engine, this exhaust is redirected to the combustion chamber, so it will pass through the nozzle and generate more thrust. Those engines have a higher Isp, but they also are way more complex and expensive to design.

The full flow engine is simply a variant of the closed cycle design.

I have my next project: IJN I-19. I'll be going off this stuff for the most part, as well as Wikipedia and this blueprints site I cannot recall right now:

Beauty of a submarine. Sunk USS Wasp and USS O'Brien, and damaged USS North Carolina. My favorite submarine. Not much on Wikipedia, but her service history is very interesting.

Haaa...
You have been caught in first post.
Using Stretched engines is cheating.

I only did it once, and I didn't know the stuff I know now. I never have stretched engines after that, not even for hobbie builds.

I-19 - chan!

And I don't even use that rocket anymore. I have a more efficient one, which can go farther and looks better, with no stretched engines.

Hell yeah my friend! I wonder which submarine I should do next...
