Thanks, I know there are equations to make a proper combustion chamber though. I know that the chamber needs to be a certain length and diameter in relation to the nozzle.

Good evening all, I was wondering if anyone would be able to point me in the right direction to equations in regards to designing a proper combustion chamber for a rocket engine, as well as for the throat/De Laval nozzle as well. I've looked around and I can't seem to find anything that...

I was wondering if anyone here happens to know the temperatures related to the SSME's ( or any rocket motor like it ) exhaust just as it passes through the nozzle? Actually, temperatures in the combustion chamber, nozzle, etc would be beneficial to know as well. Thanks again.

Sure. I guess that would work. Anyone got a direction to point for me to do some calculations with differing altitudes and stuff for max Q etc?

What would happen, if you could somehow launch a space worthy rocket from an LTA at an altitude higher than max Q? How much more efficient, etc would it be to have V naught at an altitude where max Q is?

Well, I was thinking because they can lift ~50 tonnes or more, and so if you had no cargo, and a small pressurized cabin then I would hope it would be possible to even higher up than 100,000 feet.

I'm still just saying theoretically though, how high could it go.

If the cabin of the dirigible were to be pressurized, how high do you think it might be possible for it to float up?

Does anyone happen to know the highest a zepplin has gone, and what the theoretical max it could reach? What would be the restrictions that would keep it from reaching a higher altitude?

On the same lines of space rockets, anyone know where I can get the volume of exhaust gases created by oh say the solid rocket motors, or the like?

I had read somewhere, don't have where at the moment, that at lower speeds the efficiency of the rockets are much less efficient. But as the velocity of the craft approaches the exhaust velocity it become extremely efficient.

Would it be possible to get probably the first 15 or 30 seconds in increments from about 500 to 1000 ms?

Well, first off I finally got around to making an account here. Enough with the introduction, let's get to business. I have been trying to find to no avail the acceleration that the shuttle experiences. I know that the shuttle is designed to go up to about 3G's but what I am really looking...
