How tf did this happen

There was a car that somehow got there that got missed when they closed the roads

I love the red stone rocket engine

Yes it was watered down ethanol to not melt the engine

It uses water expansion for the turbo pump

*peroxide

Into steam to drive the pump

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

How did the machine those metal parts before CNC

Yes

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

How did they cool the lunar assent engine.

It had a pintle injecter

But how does a hypergolic not corrode the regen cooling channels

Yes

Is ammonia hypergolic with lox

Cough username cough

Lol

The proton is a weird rocket

And like 3 uperstages

All hypergolic

With a ISP of less than 290

And a horrible dry mass

Still

They wanted to launch human moon missions on that

When the n-1 hit the fan

And didn’t the have the NK-33 at that time

Haha ya

Even with kerosene you have a huge problem of a RUD

Methane or any other cryo boils away

If not combusted

Yes

Yes

And makes the engines have horrible engineering problems

With the TWR

Expander cycle is the best

Yes it’s too expensive if it’s not reused

And the rs68 failed to live up to its promises

A expander bleed cycle is the best option for a hydrolox first stage

It has good thrust and low complexity

It’s impossible to do that with a closed expander

For a first stage

True

It depends on your design consideration

The raptor is probably the the most complex modern engine

The pressures in the GG lines are 500+ bar oxygen

But the main advantage of a full flow is low turbo pump temps

Because one is so fuel rich and the other is so oxidizer rich

When it’s ready

FAA with starship currently

T-38 inbound to boca chica!!!

The best airplane is the wb57 change my mind

SN9 is ready to fly

the FAA just scrubbed it
