Plane on a treadmill poll...

[joecoolfreak]

CORRECT! in fact it negates them! +1 for someone with some damn sense.

How does the ground moving in the opposite direction affect lift, drag etc....
Here...lets do another experiment... a plane is flying 3 feet over the ground and then fly's over a huge treadmill...how would that effect the plane? The answer is it wouldn't. The only purpose of a plane's wheels touching the ground is to reduce rolling resistance until the plane reaches a high enough speed to take off. It doesn't matter how fast they go or slow. The plane's speed is determained by how fast it's engines can draw air through and push it.

did you open my link? I think that explains it pretty clearly.

how does the treadmill make wind pass over the wings? it doesn't! thus the plane won't fly.
the propeller dosen't "push the air over the wings of the plane. it simply "moves" the plane when the wheelz aren't touching the ground. to KEEP THE AIR FLOWING OVER & UNDER THE WINGS!
yes the planes "speed" is determined by the engine. NOT IT'S ABILITY TO FLY!

someone, anyone I don't care who.

go out and buy a remote controlled airplane. make sure not to get 1 that's TOO BIG. as it won't fit on the threadmill.

this weekend we can go to my gym crank up a threadmill put the plane on it and watch it do nothing except buzz.

and when I prove this foolish theory wrong I get to keep the airplane. But(and it's not like this is possible anyways) if I am wrong I will pay the challenger double the cost of the plane.

any challengers wanna lose some cash?

*saturday night after 9pm I will not be avaiable. UFC 61 will be on!!!*

--> Put on some skates.

--> Stand on a treadmill.

--> I will tie a rope around your waste and ENSURE that it is EXACTLY parallel to the ground. (to not exert any downward force on the mill)

--> I tug on the rope... what happens between the skates and the treadmill?

Your answer here is gonna tell me a lot about your thought process (and lack therof... LOL).

I would then be pulling myself FASTER than the treadmill. what's your point? I could go forward without the treadmill and with alot LESS effort. so why? are you trying to make it HARDER for the plane to fly?

why don't you take up my challenge?

I don't think you people know what you're trying to do.

This is the part that you don't get....there is no power supplied to the wheels. The propeller moves the plane regardless of whether or not the wheels are touching the ground. The speed of the ground in any direction is completely moot. Let me use yet another example to prove you wrong. Lets say we are talking about a plane with skids or floaters that lands and takes off from the water. Is it possible for the plane to take off against the current? Of course. The sea plane doesn't have to find a spot where the water isn't moving... Why? because the means of thrust as your article pointed out is from the engines and ultimately from the turbine or propeller. That thrust is completely independant of the ground as it pulls air or pushes it and the treadmill isn't even part of the equation.

moot? I don't think so.

only if the plane is GOING FASTER THAN THE CURRENT! fast enough to take off!

if I'm sooo wrong. take my challenge. free $$$ for you.

now, if you're talking about making the plane go FASTER than the threadmill. then yes it could take off...if it gained enough speed. NOT if it traveled @the same speed(remain in 1 spot) as the treadmill. plain and simple

If it remained in the same spot...see Baby J's answer...ie the plane isn't going anywhere, so it's speed is 0 and therefor the treadmill wouldn't be moving. The hypothetical treadmill here matches the speed of the plane itself, not the wheels.

so what's your point? if you're going to make the plane go faster than the treadmill then what's the point? you're just making it harder for the plane to fly. not impossible, just harder. wtf is the point?

You are not making it harder, you are just making the wheels spin faster. The entire point is that people like you have a hard time grasping that there are vehicles that move by the thrust of something other than their wheels and thats why some people automatically assume that the plane won't fly. A plane's wheels are nothing more than bearings to lower the rolling resistance to taking off. It's not like anyone is suggesting that we build a runway that is a moving sidewalk. It is just an exercise for the mind to think "outside the box".
