Those rockets practically ran on vodka they had to use a 70-30 mixture to keep things cool in the combustion chamber

Ik

It's really cool what they could do 60 years ago

Ethanol is really good, because you can water it down

How did the machine those metal parts before CNC

Kerosene doesn't mix with water

Yes

They must have used some kind of mechanical CNC-style machine

Mixing with water reduces efficiency , it’s only for the engine to not melt

Yeah

Kerosene also has advantages, as long as you're using regenerative cooling

How did they cool the lunar assent engine.

It had a pintle injecter

Yeah, so an ablative combustion chamber wouldn't be good with a pintle injector

But how does a hypergolic not corrode the regen cooling channels

Idk

Hypergolics are just nasty

Yes

I just stay away from those

Is ammonia hypergolic with lox

I think it is

Cough username cough

oh

Lol

I just realized how ironic that was

The proton is a weird rocket

Shit

Yeah

I mean, it does have a very good payload capacity

And like 3 uperstages

All hypergolic

With a ISP of less than 290

They call it "the devil's venom"

And a horrible dry mass

It's an old rocket, so it's to be expected

Still

They're just begging to test the angara

They wanted to launch human moon missions on that

When the n-1 hit the fan

Yeah, that would have been a disaster
