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
Not safe at all
And didn’t the have the NK-33 at that time
Haha ya
That was an environmental disaster
It killed all the wildlife in Baikonur
Even with kerosene you have a huge problem of a RUD
Yeah
Pretty much with any highly energetic fuel
Methane or any other cryo boils away
If not combusted
Hydrogen is pretty good, but it has it's own problems
Yes
It has a reeeeally low density
It leaks through the tanks
And makes the engines have horrible engineering problems
Yea
With the TWR
Expander cycle is the best
The RS-25 is a good one, but it's super complex
Yes it’s too expensive if it’s not reused
It's like 40 million dollars for a single unit
And the rs68 failed to live up to its promises
A expander bleed cycle is the best option for a hydrolox first stage
Yeah
It has good thrust and low complexity
It’s impossible to do that with a closed expander
For a first stage
Yeah
The Raptor is probably the best, since it uses Methane
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
