Re: A Plane Problem

But it's not accelerating anywhere :-(

It's just making it's poor baby wheels spin faster whilst maintaining its position on the treadmill.

If the treadmill was moving forwards at 180mph or something as well, then I could accept this, but if the engines are just making the plane try to move forward (which is being cancelled out by the fact that the object which the plane is sitting on is moving equally backwards) then it's not going to actually be moving anywhere.

Thus no airflow over wings.

Thus no lift.

I'm open minded, but someone better explain it in very ****ing simple terms to change my mind.

Re: A Plane Problem

The plane does move forward and does get airflow over the wings.

The wheels aren't what powers the plane, it's the engines, and since the wheels have no effect on where the plane goes, a treadmill has no effect on where the plane goes either.

The issue is not so much that the conveyer cancels out the plane's forward thrust, but that, because the plane's wheels are free spinning, the opposite motion has no effect whatsoever on the plane's ability to accelerate

I don't know if that's clear I'm pretty confusd myself. I understand it but it's difficult to explain


IN FACT it WASN'T resolved by mythbusters.

First some small-scale tests were performed with a model airplane on a treadmill and the plane was able to take off. For the large-scale test, the MythBusters used a 400 pound ultralight aircraft with a 2000 foot tarp under it. The tarp was pulled backwards to simulate a moving runway. The ultralight pilot had no trouble taking off. This is because the thrust of the airplane engines acts on the air, not on the ground.

This guy's spelling isn't the best but he thinks the same as i do on this subject:

tom:
flawed test. The original hypothises was that the plane would not be moving over the ground. That was not the case in this test. Plane was moving before it took off and creating air over the wings which is what it takes for a plane to create lift. That light sport plane used in the experiment has a big engine for its weight and does not need much air flowing over the wings in order for it to fly. Myth is definetyley not busted that was the worst put together experiment I ever saw. Do it right myth guys and read up on basic aerodynamics so you know what should happen for a plane to fly.

January 30, 2008 at 10:17 PM



* THE TREADMILL MEANS THAT THE PLANE IS STATIONARY RELATIVE TO THE GROUND

* WITHOUT FORWARD MOTION THERE IS NO AIRFLOW OVER THE WINGS

* WITHOUT AIRFLOW OVER THE WINGS THERE IS NO LIFT

* WITH NO LIFT THE PLANE DOES NOT TAKE OFF!!!

Re: A Plane Problem

The treadmill doesn't mean the plane is stationary relative to the ground at all dude. The treadmill acts on the wheels of the plane which, while now turning really fast, in no way impede it's movement forward. Thus the plane will move forward, air will pass over the wings and it will take off.

Where it the hypothesis does it state that the plane wouldn't be moving over the ground? It states that the treadmill will rotate at the same speed as the plane in the opposite direction. There is no way to conduct an experiment where the plane wouldn't move forward in these conditions since it defies the laws of physics.

Re: A Plane Problem

The treadmill is meant to move at the same speed as the plane. No power the treadmill won't move, once the plane starts to accelerate the treadmill will match this speed in the opposite direction, all this will cause is for the planes wheels to move at twice the speed of the plane itself. The wheels, and how the plane interacts with the surface it is taking off from have no bearing on it's ability to move or gain lift.

Re: A Plane Problem

The engines provide thrust. The thrust pushes the plane forwards. The plane rolls forwards because the wheels roll along the static runway by virtue of the fact that they're attached to what would be a static airplane if it weren't for the engines pushing it and the wheels removing most of the friction against the ground.

If I park my jet propelled car outside of Woolworths on a road that is a magic treadmill, no matter how fast I try to go by increasing the throttle, the treadmill is moving equally the other way, so in twenty minutes time when I get out the car, I'll still be outside Woolworths.

Attach wings to my car, and unless there's a 180mph wind coming at me, I'm not taking off.

Re: A Plane Problem

The wheels don't provide any thrust, they are simply there to remove the friction that would otherwise occur which would stop the plane from moving.

I'm not continuing with the argument any more. Once i'm a multi-billionaire though i'm going to set up this experiment properly. In fact f*ck it, Billy Gates shouldn't be sending money to Africa to help the poor and needy there. He should be finding out the answers to the questions that matter the most ... namely this!

Re: A Plane Problem

No, Jakiri is right.

The engines are creating the thrust, but the thrust is only there because of the air (Newton's third law). The thrust has nothing to do with the wheels, which although are on a treadmill, they have no part in the propelling of the aircraft.

It'll still move forward and it'll still take off, although I agree with whoever said that the wheels might fall off first.

Re: A Plane Problem

I argued under the impression that the for the purpose of this dilemma, the plane was being held stationary by the runway (by whatever means).

But like people have said, while following the original question verbatum (that means 'word for word') - there's nothing to suggest the plane is being held in one place by the motorised runway, and so one has to assume the plane is being thrust forwards by it's engine.

With the presence of forward momentum there's no way the plane couldn't take off, save for the sake some poorly placed trees for example.

The reason why I argued so vehemently is that I believed there to be a purpose to the question. From the original criteria set out in the question, the moving runway is not a factor. Given this, the argument is "Can a plane take off?" In which case the answer is going to be 'Yes' (again, save for unspecified degratory factors).

On the assumption the question had a purpose, in which case the runway would have to be a factor - then the runway in question would need to be operating at such a speed it created enough friction on the wheels to keep the plane stationary - in this case the plane wouldn't take off.

But as I've learned that's not what the question asked at all (even if deep down, it REALLY REALLY wanted to). So yeah, the plane takes off.

So if Ste mother was turning tricks on a treadmill would anyone ever take off?

The real question is:

"If Ste's mother was turning tricks on a treadmill would anyone ever get off?"

And the answer to that is "Yes, but because Ste's momma is so ugly they'd only be able to do so by dismounting from said treadmill."

Re: A Plane Problem

I can't believe im posting on a 5 year old POS GD thread.... what is my life coming to.

Quote:
The original hypothises was that the plane would not be moving over the ground. That was not the case in this test.

Imagine a rope tied from the front of the plane to the post at the front of the treadmill. If you pull that rope, everyone should be able to see that the plane will move forward. The essentially frictionless wheels are irrelevant, they just spin faster.

The effect of the engine is the same. It pulls the plane forward through the air.

Your problem is that your premise would not work. The only way the plane will remain stationary with the engine on is if there is so much friction between the wheels and the surface that it creates the same force going the opposite direction... but in that case it would have been forced off the back of the treadmill while idle.

I am going to go cry now.

I'm fairly sure that I made a post on this thread a couple of years ago of something along similar lines, that the question makes no sense based on the sum total of the information provided.

The only way to discuss the premise of the question is to put it into logical contexts. Most of the discussion that has taken place has been postulation, and the idea that a question asked, merits a logical approach to formulating an answer. In this case, given that the provided 'conditions' of such an experiment couldn't exist without extreme hypothetical solutions, a logical answer can not be reached under such illogical circumstances.

The only 'arguing' seen in this thread wasn't ever about whether the plane could take off or not, people were merely arguing over how to approach the question.

I'm sure I didn't word it quite like that though.

Still, it was one of my favourite threads I've seen on a forum.
