Currently in California and I’m sure I heard a tv presenter say at launch the Saturn 5 burnt a A380 max fuel capacity, 259t every 19 seconds for 2m 41 seconds.
Mind boggling.
its the fuel pumps that get me !Mind boggling.
almost 50 million watts, just to pump the fuel into the engine !
but as you say 2800 gallons (12,710 litres) of fuel per second is one hell of a flow so 320,000 litres in ~25 seconds

Yes, it's a gas turbine, which is the rocket engine. It's the same thing.
Which isn't a jet engine, which the a380 has.. Somewhat confusing..
Didnt mean jet (i know i typed it in haste then edited it ), but the fuel pump certainly isnt a rocket engineWhich isn't a jet engine, which the a380 has.. Somewhat confusing..
mind you, its small fry compared to the two 670MW turbines I have about 40 meters away, though they are a little longer

Quote wiki
"A rocket engine uses stored rocket propellants as reaction mass for forming a high-speed propulsive jet of fluid....Compared to other types of jet engines, rocket engines are the lightest and have the highest thrust"

Liquid fueled rocket like what we are talking about.
Try one of those without a fuel pump.
? still dont get where your going.Try one of those without a fuel pump.
The fuel pump is not the rocket, its a pump driven by a gas turbine, not a rocket in itself. It delivers fuel and oxidiser to the injectors. Overall you could say it forms an essential part of the F1 rocket engine, but its not a rocket in of itself.
ie, i dont get

A rocket engine is a fuel pump which has a few turbines.

I’ve struggled to keep up with them all, the problem is finding interesting new info as obviously the majority of the programs are all the same
I find a few good documentaries make their way to Apple iTunes, although I have recorded many of these in the last few days I think I shall get a few digital copies if they get to iTunes. Then Take my time. Price depending of course.I have the Saturn V tests on DVD, a firm called Spacecraft Films put then to gather from NASA footage (hells bells, just checked the prices 2nd hand!!!! might not be on sale anymore). They are rather good and no commentary if memory serves but DVD, not sure if they have had a bump to Blu-ray. A lot of what I have seen in the recent TV stuff comes from footage available (not all easy to get admittedly).
This does need airing.

Personally I keep an eye on threads like this as you get some great info and insights.
