Taking off requires a upward net force. This is caused by LIFT. So, with Newton helping us out a bit here, we will prove that the plane cannot take off:

Starting out, at v=0, the plane is not moving through the air, hence the total net force is still a vector pointing DOWNWARD (this is the airplane's weight). When the airplane starts moving (by providing forward thrust) the conveyor belt reacts and does not let the plane roll forward RELATIVE TO THE AIR. Velocity relative to air is STILL zero.
Key point here: if the airplane does not move THROUGH THE AIR, the lifting force is NOT generated.

And thus the airplane does not take off.

 

Your analogy of the sea plane is correct in that there is friction (water again a fixed object, the planes belly), however the plane we are talking about has wheels that turn (unless they forgot to release the brake). Lets reverse our action, lets say the plane is going to land on this moving conveyor belt, your saying it can't, I'm saying you won't hear the "errk" of the tires because the conveyor belt will be traveling the same speed. When the brakes are applied and the wing flaps down the plane will slow as will the conveyor.
My .02 cents worth, we are still at the lounge.

 

Can I join you guys? I'm buyin! lol

 

OK I lied this is my last post.
Hoss you might want to check this out. http://www.avweb.com/news/columns/191034-1.html
I hope the link works.
I'am not even gonna say if it will fly or not. My head hurts.

 

Okay...I've got a Triple 7 pilot that says the plane won't move. That means I win.

 

Yes... 10 mph.. my understanding is this is a typical bulldozer:

the track on top is the same as the track on bottom.

 

OR:

The plane can take off only under these circumstances.

If the engines were routed directly infront of the leading edge of the wing thereby creating pressure difference between the top and bottom (lift) of the wing effectively making it a vertical takeoff machine

 

The problem with their experiment is that it did not meet the conditions set forth in the scenario. They DID have a conveyor runway, but it did not exactly match the speed of the wheels (otherwise the plane would have never moved).

 

I think that's the rub. The conveyor matches the speed off the wheels not the plane.

YES, YES, YES! You got it! That's what I've been trying to say! Now if I can just get Hoss & derk to think past earthly bonds.

 

The speed of the plane is 0 mph.

 

Hoss, You are a very intelligent man (should have gone to Baylor, buts that's another story ) think this through before you type another post.

To your theory, you are correct if the wheels are driving the plane. BUT the wheels are not driving the plane. The engine is pushing on the atmosphere independant of the conveyor. The only way to cancel out the forward motion of the thrust of the plane is to tie it down or create a headwind to match the thrust, but even in the latter senerio the plane would lift off at rotation (lift off) speed and fly. (ground speed 0)

 

Geico266,

Look what you started....WE WANT ANOTHER BIG BRAIN TEASER!!!!

 

I just a bill in the mail for wasted bandwidth from Jack & TOP.

We could have built the conveyor!
