Plane on a conveyor belt

[zbrown]

Wow how did i miss this..... the rules of this experiment are vague

I am not gonna get into the whole conveyor part because you will not change what people think

there is only one point i want to make

Lets just disregard the conveyor and say we chain the plane to a stake in the ground behind it, so it cannot move forward at all.....

1. A prop plane with a enough thrust will lift off the ground even being stationary, if there is enough air moving across the wings from the prop

2. I dont car what anyone says, a jet/rocket powered plane (even with unlimited thrust) is going nowhere as there is no air being moved across the wings

3. Gary is a Homo

its just like a car on a dyno.. strap wings on you car and see if it will fly....................negative

How does a VSTOL aircraft take-off????? hmmmmmmm

1. Maybe

2. Completely irrelevant to what we are talking about, but yes, a stationary plane will not take off (excluding Harrier, etc...) This plane is NOT stationary however and there is nothing holding it still.

3. LOL

Obviously I was talking conventional............hmm .... better clear up the space shuttle and Saturn V will go somewhere to for the smart asses

I can see how some can be confused though....... the question kind of states that the plane will not move forward in relation to its relative original position

atleast someone could take it that way...

and you and I both agree a stationary plane is going nowhere, cept what i said about a prop plane

Gary is still a homo....

[Grr]

fuck U, i think im the only one that actually posted a clear scientific answer in this thread. You can think whatever you want, but the proof is in my post, simple as that.

Hey zac, if the plane remains stationary, there is no conveyor belt, and the whole question takes place in the 17th dimension, and ive been there man, its crazy, you dont want to know

Actually, it doesn't. It says the plane moves one way and the conveyor moves the other way. It doesn't say the conveyor stops the plane from moving.

Gary is still a homo....

You'd know better than I would (or so I hear)

I basically tried to use simple english to explain what you did with science. Thank you for putting it out there in scientific form though, it was greatly appreciated.

You are making the assumption that it's the speed of the plane making it take off, and this is incorrect. Speed is all relative. When you are walking inside a moving train with it, you aren't going at 60 miles per hour. You're going at a meter a second.

Actually this is inaccurate, as you are moving 60 plus miles an hour, if the train crashed, you'd still be going 60 miles an hour until you hit something.

^^^^ yeah thats Newtons 1st law. Also if you're in a train and its going 60mph and you're walking 1m/s then depending on the direction of the velocities you're going 60mph+1m/s or 60mph-1m's

And Grr I totaly get you're whole physics explanation, I just have too much of a life to sit down and be a scientist. You're science makes sense for the most part its just you're forgetting lift and also Bernoulli's principle. Theres enough thrust to make it fly but there's no lift.

[GarageAlchemist]

yea, you worded that better than I

Hardly the same thing. On a car, the wheels propel the vehicle. On a plane, its the prop or turbine.

can you explain why there is no lift?

[bubba]

^ exactly...the plane is moving forward at the same speed as it would on a runway same airflow, lift etc...all the conveyor belt does is make the wheels spin twice as fast...so unless the wheels blow and it crashes and burns it will fly, lol

[zbrown]

Ha.... I just threw the "Gary is a homo" thing in there to piss you off

I will have to go back and read your physics lesson cuz i didn't read this whole thread

And i still think it is easy for people to be confused and think that the plane cannot/is not moving forward in space

he is saying there is no lift on the wings if the plane isn't moving forward (he is correct)(prop plane will though)...... he thinks it is not moving forward

I rethunk this for a while today. There is no way the belt will hold it back. But the start of this myth was so planes could take off in smaller areas ( off boats and crap ) Wich is not possible because the belt in no way effects the speed or airflow around the aircraft. So basically a conveyor belt will not affect the plane in any way. The take off distance will be exactly the same just with the wheels spinning super fast. I thought you guys meant if the conveyor belts hauling ass and the plane just happens to be on it rolling it'll take off.

Please show proof of said statement that the conveyor will help shorten the runway space needed. It wasn't part of the original question.

Other than that, glad you finally got it.
