Will a plane take off on a treadmill?

Now before you go debating this again wait til Wednesday at 8 and let the Mythbusters do it for you.

Jan 30 9pm EST (that's 8 for us)

treadmill isn't practical so they're using a conveyor belt, same concepts apply. Finally, we can put this to rest.

Fuckin A!!!!!!!!!!!!!!! I was hoping they would take this one on............ FINALLY!

oh and my vote stands on no it wont, from the last debate

My vote is yes it will

go time traveler style and go back in time, fuck his grandma, then shoot forward in time and then fuck his mom. Then return back to present state and call him a the product of two incest whores and hes your son and show video of you plowing the both members of his family. .

a TREADMILL and a CONVEYOR belt are NOT THE SAME!!

do you go to the gym and get on a conveyor belt to run? NO Treadmill is ment to keep the object on it in one place, a conveyor belt is ment to MOVE objects.

a plane will NOT take off from a treadmill, it most likely will take off from a conveyor belt if the speed is great enough

Ummmmm, wat?

Wing creates lift as air moves over/under it.

Are they blowing a fan on it?

and was there a thread on this I missed?

this was debated on this forum? My vote: Unless air passes over the top of the wing faster than it does the bottom, there is no pressure difference (lift) and it wont fly.

Simple laws of physics won't allow it to take off. I can't believe it was debated, or that it is on mythbusters.

I disagree... Treadmill is just a short rotating belt. Conveyor belt is just a bigger version.

If the plane is facing in the direction of belt travel then eventually with enough speed plane would fly. If plane is facing opposite of belt travel then no lift will occur.

no, it wont...as long as it's staying in place relative to the ground, not the conveyor.

ground speed/speed at wheels has nothing to do with how much lift a plane produces, it's the airspeed that does that. Therefore, if the plane is giving just enough power to equal the resistance from the wheels spinning over the conveyorbelt, it will stay in place on the belt, have no airspeed, and do.....nothing.

Not this again, but I agree with you. If the plan has no wind over the wing, it will stay in place, if they are making a conveyer with rollers to hold the plain in place it will not fly. This would be similar to putting a motorcycle on a dyno, it won't move forward because the wheels are locked in one spot.

It def wouldnt, its physics. The only thing your doing with a conveyer belt is rotating the wheels. If there is no air being blown against he wings then there is no lift.....i dont see where there is even an arguement

Take a piece of paper. Hold it up to your bottom lip and blow. You will see it start to lift. This is how a plane flies.

Wheels just keep it from skidding on it's belly. I really cannot believe this thread or mythbusters.

I'm gonna have fun watching this thread and hope it is like the one from a few years ago.

seems like common sense to me.

I think a better mythbuster thing would be, can your airplane be lifted off the ground with a huge gust of wind, being destroyed as the wind stops and the plane falls. that way, something would happen, and it would be destructive at that

the R/C flying sounds pretty cool. I'd assume that it's not a real airplane they're rigging up to fly remotely...but it'd be cool to see that, until they crash a perfectly good plane though lol

no, not enough to fly

But it might bounce around a bit and they might consider that "flight"

true, but i think (considering they are testing at speed at take-off) that it still wouldnt fly, as even though the prop is helping with lift, it isnt over the surface of the entire wing. not only that, the prop won't need to spin as fast as it would on takeoff as it is only creating enough thrust to equal the friction from the wheels, not move a whole plane through the air at 70mph.

I still vote a huge no. anyone want to place bets??

Assumptions:

- conveyor belt is 10,000 feet long, moving toward the jet
- frictionless wheel bearings
- jet applies no engine thrust

Result: wheels spin but jet does not move. (frictionless bearings means no force is imparted to the jet beyond the wheels)


- conveyor belt is 10,000 feet long, moving toward the jet
- frictionless wheel bearings
- jet applies engine thrust required for normal takeoff

Result: wheels spin at 2x normal speed, jet accelerates forward and lifts off at normal takeoff speed.

They should do the jump a motorcycle with a running car one. I sent that in but it got rejected. I even mentioned that thousands of CLSBers and hundreds of thousands of bikers need to settle this.

It's a propeller.... Wheels spinning don't do anything to the lift required on the wings...

Those who believe it will work, take a piece of paper and put it up to your lower lip. Blow and watch the paper lift. This is what makes an airplane fly.

The shape of an airplane wing is not flat. It is rounded on the top.

Google search, "physics of flight"

click on some links and take some notes.

from the preview, jamie said that they would 'set the conveyor belt at the speed the plane takes off at, and see if the plane will take off'. Sounds to me like they are doing the second one...

still a dumb myth imo, all they are doing then is seeing if the engine has enough thrust to move the plane while the wheels are spinning at takeoff speed + speed of the plane relative to the ground.

One point to consider, how can they build a conveyor belt a few thousand feet long??? so in both cases no
