No I will not argue with you; When I present basic facts and get:
"No :..because: er uh:
"Pressure gradient".
Yeah uh "pressure gradient" that's it.
So there...



TECHNICAL SOUNDING Words(techno babble) have meanings and I don't think: "PRESSURE GRADIENT" means what YOU think it means.

But I refuse to waste my time To argue pointlessly on line.

so 54 minutes: educate yourselves. on a little basic physics of gasses and forces.

Eschew ignorance!!! keerist it's A VIDEO zero effort to learn.

Just gonna leave this here: Argue amongst your flat earth selves if you wish.. Have good evening.

Everything else has progressed in the computer age except for space flight??? Odd

I worked on the Shuttle program at Rockwell International.

Rocketdyne was one of the divisions and they invented the aerospike.

Its an interesting concept. Not sure why they did not use it more, but I am sure there were trade studies.

When I worked on the Advanced Launch System, aka Big Dumb Booster, we did hundreds of trade studies optimizing every aspect of the vehicle.

I had all the deliverables, i.e., the products of that contract that we delivered to NASA. The volumes filled up several filing cabinets.

Sorry to say all the volumes and drawings were lost over the years as they moved me to different projects.

Anecdote: We were behind schedule and over budget on our design studies. One of the old VPs said, "Get the Apollo veterans in here!".

We hired about 10 retirees. They got more done in a week than 150 engineers had accomplished in 3 months. Why? They already had studied everything we needed to know.

Back in the 1960s they had 60,000 people working at my division and the amount of new science and engineering that came out was staggering.

You can get results like that when the budget is 1% of GNP and every talented person in the world is dying to come help. Hell, we were going to the Moon! We attracted some serious talent.

BTW, I often wonder how much we have lost since then. Its not just the "idiocracy effect". Kids don't get the same education I got.

Actually, those guys landing boosters on the barges is incredibly impressive.

You have to understand that we pushed every element in the periodic table to its max capability.

For example, the Space Shuttle Main Engines develop 700 HP per CUBIC INCH.

Have we discovered a better fuel than Lox/Hydrogen? Have we developed alloys with better thermal conductivity than copper?

What other turbine material can go from liquid hydrogen temp to 3000F in a microsecond without disintegrating?

We DO have a few new materials, but they are not revolutionary.

The key to new vehicles is the engines efficiency, specific impulse, and power-to-weight.

Not easy.

My fave is nuke-thermal using slush hydrogen propellant with a specific impulse of 900 seconds. You could have a vehicle the size of a 737 that takes off from a runway and goes straight to orbit without staging or drop tanks. Refuel and you can visit all of the inner Solar System out to Jupiter.

Its just a political decision.

I'm not a flat earther or a rocket don't work in space guy, but I don't think this answered the question of why a rocket works in space.

are they still using inconel for the rocket turbines ?
