Official Betting on Plane treadmill thread.

wait I have a question that may affect whether or not I want to be in on this...

is the treadmill's speed variable or constant? As in, does the treadmill speed up as the plane speeds up or are they going to keep it at a certain rate?

WTF does the weather have to do with anything?
Treadmills are indoors.

people betting that it won't take off(and not the inconclusive bets), are FVCKING MORONS...have fun losing your money.

i dont see why there is so much debate on if this is going to work or not.
if a car is being dynod is there any downforce created?

NO

there is no air moving, just the tires.

no air moving=no lift.

then did you bet? back up your statement.

btw, your statement isn't comparable to the experiment.

tragic flaw grasshopper...

Here is my bet. $200 or a multitue of people to total $200. (If you only want to bet $1 or so, that is fine.)
Place your bets with me.

I say that the plane WILL take off.

Any takers?

Betters:

shortyg83 $10

Flipx99 ($10 says the experiement either fails or is inconclusive)

canaan $50

i say it flies too.

x2 it flies, Wheels spin freely they arent drive wheels, so its not like a dyno.

but im a poor college student no bets //content.invisioncic.com/y282845/emoticons/frown.gif.a3531fa0534503350665a1e957861287.gif

workin' on it.

I said I was going to up my bet to $75 if the other guy came in for the HU install, but he didn't. Another guy came in for an amp install though...but I'm not adding any more $. I'll let you off easy w/ $50 //content.invisioncic.com/y282845/emoticons/smile.gif.1ebc41e1811405b213edfc4622c41e27.gif

Well, its off the to Bar-n-Grill for a burger and a beer.

Wish I could bet, but I am on Jntar's side.

The only way it won't fly is if they screw it up, or they are not describing the myth fully.

Plane flies from propeller thrust, not the wheels thrusting. As said over and over, the plane will still build up speed to take off, the wheels will just move 2X faster underneather it. . .

I want to hear your setup...

So.. you're saying we could potentially save the space required for planes to take off and we haven't yet..

Holy shit. Someone call the Navy. I bet they would love to get a hold of information like this.

They could have saved billions upon billions of dollars putting a treadmill onto aircraft carriers instead of designing planes to launch in shorter distances or take off vertically.

No we are saying the treadmill will have no effect either way, whichever way the treadmill goes it will only contribute a tiny amount to the plane taking off or landing. The frictional force exerted by the wheels is a minimal force when describing both the accelation and deceleration of the plane. If you could somehow NOT deploy the wheels on a plane and land it on a treadmill moving VERY fast in the opposite direction,sure you can land a plane in a small space that way, but it'd literally be a crash landing onto a platform. As soon as the wheels go down they energy is simply spinning the wheels. If the only force driving the plane was the force of the wheels against the ground then yes, we could use a treadmill, but it's not. The main force is the massive amounts of air that the turbines displace. They shoot air backwards which moves the plane forwards, regardless of what the wheels are doing. If the wheels are not moving they'll begin to roll forward, adding a bit of extra acceleration to the plane. If they were rolling backwards they will continue to do so until the planes speed moving across treadmill exceeds that of the treadmill. Then they will roll forwards.

Ps. This is sort of a tricky problem. As a 3rd year physics student I had to analyze it for a good 30 seconds to figure it all out.
