What is thrust?...Explain what thrust is and how you gain it from your vacuum chamber.

I seriously doubt that you people know what thrust is. That's why I ask the question.
I don't expect the likes of you to grasp any of it. You're just a clown.

And I'll just add this:
If a rockets engine requires leverage against atmosphere to create thrust. Why do they gain thrust as they gain altitude?

Surely it would loose thrust as the atmosphere gets less and less dense and thus less molecules to create the leverage against.
They don't gain thrust as they gain altitude. They lose thrust but keep a normal speed due to fuel burn, making the rocket lighter with every vertical push into and against, atmosphere.

Apart from air density at 80,000 metres is over 1 hundred thousand times less than ground level.

All vacuum engines are tested in vacuum chambers. And they all give out more thrust in a vacuum than in atmosphere.
How in the hell can you test a vacuum engine inside a vacuum chamber without it ceasing to become a vacuum chamber?

Also, what the hell is a vacuum engine?

What is thrust?...Explain what thrust is and how you gain it from your vacuum chamber.

They have tested a variety of rocket engines at plumb brook. It is the largest vacuum chamber in the world. Used to test rockets at simulated altitude and has been used to test rockets in a vacuum aswell.

Thrust is equal to:
F = m dot * Ve + (pe - p0) * Ae
m dot=mass flow rate
ve=exhaust velocity
pe=exhaust pressure
po=Atmospheric pressure
Ae=Area

The main reason it functions better in a vacuum is. Ve (exhaust velocity) There is no/little back pressure restriction on the exhaust so exhaust mass can flow easier and faster in a vacuum resulting in a higher thrust.

The reason why it is called a vacuum engine is the Ae or (nozzle area) is much larger than an atmospheric engine. The reasoning is because a rocket nozzle is most efficent when nozzle pressure is equal to external (atmospheric pressure). They are designed to have the largest area nozzle possible without adding too much mass to the craft in a vacuum situation. This is to keep the nozzle pressure as close to zero and as efficient as it possibly can in a vacuum.
Unbelievably contradicting.

How so?

Also, the thrust of a rocket is the reaction to the force with which the rocket expels mass, namely the force which accelerates the rocket. Satisfied now?

This subject has nothing to do with the earth being flat, nor is is a 'debate'.

Ergo it is bullshit from the get-go...

False dialectic bullshit on a proven shill-forum.

Fuck off the lot of you.

Back to real science; this is all you'll get from now on:

A rocket in space very much resembles a pressurised vessel separated from a vacuum by a valve.

Which is remarkably similar to the conditions of the Joule free expansion experiment.

Once the valve of the Joule expansion experiment was opened, the pressurised gas released into the vacuum was found to do no work.

http://pubs.acs.org/doi/pdf/10.1021/j150043a002

http://web.mit.edu/16.unified/www/FALL/thermodynamics/notes/node33.html

http://www.etomica.org/app/modules/sites/JouleThomson/Background2.html

This proves a gas-powered rocket would also do no work in a vacuum.

PROVES, markjo.

Here is the definition of 'work':

No work=no force=no movement.

conservation of momentum:

mass of fuel burned*speed burned fuel is ejected=mass of spacecraft*delta-v of rocket.

If you burn 50 kg of fuel and it ejects at 1000 m/s, and your rocket weighs 5000 kg, it would change the rocket's velocity by 10 m/s

How DARE you suggest that an experiment designed specifically to CONFIRM conservation of energy, & thus conservation of momentum, somehow defies it?

How fucking DARE you?!?

Papa lying again. Using useless information claiming it as fact.

Joules free expansion has more to do with a refrigeration system than it does a rocket.

You don't know what that experiment is experimenting about. You have misinterpreted it. Just like you don't understand Newton's Three laws.

For every action there is an equal and opposite reaction. This is the DENPRESSURE law.
What does "equal and opposite" mean in 3(4?)-dimensional space? 
How is the law proven to be true?  How can it be observed in action? or verified? 

What is a reaction? 
When does a reaction start?  or end?

You moved it because you are a shill & did not want non-members to be able to view it you silly little fraud.

Because I was correct all along & you know it.

Your other fraud-mod shill ID, tehEnjynerr, did exactly the same thing before disappearing.

Thanks for proving beyond any shadow of a doubt that you are a shill & this is a shill-run forum though.
