Just combustion chamber and nozzle, no preburners, turbopumps and other stuff

Here's what I've already found: https://space.stackexchange.com/questions/41150/what-is-the-heaviest-part-of-a-rocket-engine

Yes, I have tried to find some information on this and the best what I've found is here: https://space.stackexchange.com/questions/41150/what-is-the-heaviest-part-of-a-rocket-engine I'm interested in complex and high-thrust engines like SSME and Raptor

What is rocket engine combustion chamber plus nozzle's mass approximate percentage of the total engine's mass? Thanks

How low is Space Shuttle thermal protection's heat conductivity? Thank you

My theoretical installation needs to produce ~5 kg of liquid methane per second to rapidly fill a large fuel tank

I am speaking of methane

What type of operated gas liquifaction units has (things being equal) the least dimensions, mass and is easiest to transport? Thank you

I was studying theoretical physics in the university for 2.5 years before giving up this speciality. If I study physics ~2 hours daily plus 3 hours every weekend myself and individually with teacher, will I be able to do serious research (write papes that will be cited and will have influence...

I know that the word 'postulate' means something without explanation, so probably there are no words like 'electrons have stable orbits and radiate only when transiting from one to another, because .....' in quantum mechanics books, but were there at least worthy of mentioning attempts to...

What will happen with the electromagnetic wave reaching an antenna when this antenna is not resonant on the frequency of the wave: will it reflect from antenna or pass through it? Thank you

Thank you very much for all the help! It is very valuable!

Thank you!

I want to be, as well as possible, prepared for work as an aircraft mechanic (info about business jets is also good for me). My aeronautical engineering university degree does not teach much about technical/mechanical aspects of aircraft engines.

Yes, I am interested in that because I want to work as an aircraft mechanic. I am getting university degree in aeronautical engineering soon, but we did not study much about technical/mechanical aspects of turbofan engines so I want to improve my knowledge in this myself to be prepared for the...
