If rockets don't work in space how do satellites get into position?

They don't, Mr. 'I can't-believe-it's-not-a-bot' Inquisitive.

But nice distraction from my destruction of markjo...

here it is again, for those who missed it:

No, I didn't forget about the vacuum.

Yes, you did.

You have to, or your fraud-rokkits can't function in your fraud-shpayze.

What's next?

Oh, this:

gas has mass and therefore any acceleration of that gas results in a force .

Fantastic - The Force!

Just like Star Wars eh?

So, anyhoo; you seem to have learned Newton's 2nd Law: F=ma...

Good! That's progress.

Now, simply extrapolate your gas-with-force into a Resistance-less vacuum environment, apply Newton's 3rd Law & Bingo!

Rockets do not work in Space.

Thangyew & Goodnight!

Here is a post from a few months back where mainframes showed he did not even know what the general physics definition of the term 'evacuated' is:

I mean; look at this garbage:

Quote from: Mainframes on October 28, 2015, 06:25:30 AM

Quote

Free expansion is an irreversible process in which a gas expands into an insulated evacuated chamber. It is also called Joule expansion.

It is not that gas cannot do work in a vacuum. It is that gas does no work when expanding into an evacuated chamber because all of the effect net to zero.

What, exactly, is in that 'evacuated chamber' that the gas does no work whilst expanding into?

Could it be a vacuum?

Why yes; yes it IS a vacuum.

Thus, mainframes completely contradicts himself in one sentence!

& what 'because all of the net effect to zero' means is anybody's guess...

He does this all the time, yet expects us to believe he has a masters in science...

LOL!!!

Cool story bro...

His latest post shows that he has learnt nothing since.

Also note that, for all their talk of the combustion chambers of shpayze-rokkit enjynns such as the J2, the clown derfers seem rather reluctant to actually show us any of these miraculous devices...

This is because, if they did, it would be obvious that they were entirely open to the infinite vacuum of space, & could not possibly work as claimed.

*Yawn!*

Of course I know what the term evacuated means. That's why I used it. The emphasis was on the fact that a chamber is involved. Free expansion requires a closed system otherwise it simply does not hold.

Now, simply extrapolate your gas-with-force into a Resistance-less vacuum environment, apply Newton's 3rd Law & Bingo!

How many times do I have to tell you that the expanding gasses are acting against the walls of the combustion chamber, not the vacuum of space?

Are you retarted?

Are you illiterate?

Or are you just a troll who enjoys wasting everyone's time?

How many times do I have to tell you that the expanding gasses are acting against the walls of the combustion chamber, not the vacuum of space?

Pathetic.

You are incapable of rational thought.

Please stop replying to me.

A resistance less environment means that the gas is not impeded BUT it still must be accelerated. Therefore a force acts on the gas. Newtons third states equal and opposite reaction occurs. Therefore the gas exerts a force on the rocket.

Rockets DO work in space!

So no counter argument then. Back to your bridge and stick to goats Papa.

Just spam out your rattling billiard balls analogy & be done with it, psycho.

You don't even understand the composition of matter and how gases behave. Muppet.

i have a degree and you clearly don't. I can feel the jealousy oozing from your every pore. Sorry little boy, go back to masturbating in your parents basement.

If there is no resistance within the combustion chamber, then there is nothing to stop the gas from expanding and exerting a force against the combustion chamber.

Presto, rockets do work in a vacuum.

It's amazing that you can go to the effort of digging up months old irrelevant posts but you can't be arsed to answer a simple question like whether or not hypergolic liquids can mix in a vacuum and spontaneously combust to produce gasses in a vacuum.

Maybe if you put as much effort into researching mass flow as you do in your trolling, then you might actually learn something.

When you want to wake up from your fantasy world I'll be around waiting.

I don't know what it is you are waiting for, but I'm still waiting for a quote.

It sure is nice not responding to your crap.

Anyways, I'm waiting for you to acknowledge that you said something wrong.
Even the resident Looney Tune thinks you are wrong.

Define proof. The typical definition (evidence exclusively for something) is untenable in any realistic, scientific context.

Oh, look, I did so months ago & again this week:

  Can two hypergolic liquids be sprayed together in a vacuum and spontaneously combust producing combustion gasses?

Oh, look; I already answered this months ago!

Quote from: markjo on October 27, 2015, 07:15:33 AM

Just out of curiosity, does that include hypergolic propellants that ignite on contact when sprayed into a combustion chamber?

LOL!!!

What does it matter?

If the combustion chamber is open to the vacuum (which I'm still not sure you agreed upon or not, as you are such a shitposting snake... Luckily we all know damn well it IS open to the vacuum anyway), then any gas produced will simply expand, freely, following the path of least resistance & doing no work.

No matter how you twist & turn, all the laws of physics tell us that a gas-powered rocket simply cannot function in a vacuum.

Because YOU CANNOT PUSH ON NOTHING.

*Yawn!*

Do you recall me urging you to get tested for Alzheimers, markjo?

Well, no, of course you don't...

Because your Alzheimers made you forget I did so.

It is a terrible disease.

I can only repeat my above request that you seek treatment for your memory problems.

Also, stop TALKING about your magical combustion chambers & SHOW us one; the J2 will suffice.

Thank you please Mister The Liar!

Thank you please Mister The Liar!

Definition of a liar: Anyone who disagrees with Emeritus Professor of Rokkit Engines in Space, Dr Papa Legba, who knows everything about choked flow in de Laval Nozzles and supersonic flow!

Ii is reported that he has developed a way to propagate influences back up a supersonic gas flow.  This is reported to lead to great advances in hypersonic aircraft design, leading to a great reduction in shock wave generation and may lead to an imminent NoBull Prize.

Stop parroting your fellow Australian youtube mega-Troll Kris de Valle & learn to read.

Also, stop TALKING about your miraculous shpayze-rokkit 'combustion chambers' and just SHOW us one.

The J2 would be nice; it went to teh munn, you know!

Toodle-pip, Twelve-Steps!

The J2 would be nice; it went to teh munn, you know!

And how it came back; how did the braking/deceleration process from ~40,000 km/h to "parachute deployment speeds" work?

Can you flow more into a chamber than out of the chamber?

Tell you what, why don't you SHOW us exactly what these magical shpayze-rokkit Combustion Chambers you are all so obsessed with look like, then we can all have a good guess?

The J2 being the one I suggest...

Thank you please!

Answer the question first.

Ok so the answer is yes, you can flow more into a chamber than out of it. This ends your claims that a rocket can't work in space.

I didn't say that it was.

You suggested the J2.

I provided a more modern example.

Are you suggesting that the J2 combustion chamber is somehow functionally different from the example that I provided?

The combustion chamber of the J2 does not 'function' at all.

Please stop trying to slip voodoo past Legba.

Legba sees all voodoo.

All voodoo all the time.

Please to stop voodoo now bad man markjo thank you please!

Anyhoo; you did at least provide some kind of photo of a 'combustion chamber' (lol!).

We will examine, & laugh out loud, at it at a later date.

But tonight is Christmas Eve; all Legba intends to do is have Fun.

Clown Derfers will entertain Legba!

All Clowns to make Clowning for entertain Legba now please!

Thank you please!

How can it not function? You agreed you can flow more into a chamber than out of it.
