So that the higher pressure in the chamber, the more you can expand it through that nozzle to speed it up out the nozzle.

So they're basically just using that to cram it together.

You choke it down.

There's a throat.

You call it the DeLavelle nozzle.

It converges and then diverges.

And what's happening is you're taking that high-pressure gas.

The higher pressure it is, the more you can expand it out the nozzle.

Right.

It's, I have, I have like, when I talk about this stuff, sorry, I have like, it takes me normally an hour to explain, like I have an hour long videos on, on how, how these pumps and stuff like that work.

So I'll try to keep it succinct for you.

But, but that's all they're doing is they're shooting it.

They're shooting mass out the back and it's an equal and opposite reaction.

Just like a fire hose too.

You know, a fire hose doesn't push against firefighter because the water's hitting the air.

and pushing the air, and that air pushes back on the hose.

It's literally the mass flowing out of the nozzle is what's pushing equal and opposite to the fireman and against the hose.

And the same with the recoil of a gun.

It's not the bullet hitting the air that makes the gun shoot back at you.

If you take a gun into space, it's still going to have recoil because it's shooting the mass, so the equal and opposite reaction happens to you.
