AirPlane on a Teardmill and Mythbusters

Was watching Mythbusters last night and it was announced that the long awaited Air Plane on the tread mill myth will be next week on Wednesday.

Finally there will be an answer. LOL :D
 
it flies

personally, I don't trust these guys much... they had an episode where they "proved" that you couldn't robin hood an arrow with another arrow... yet I've seen and done this myself more than once...
 
The airplane will fly but not very easily. You have to add the treadmill speed to the ground speed to get the neccessary take-off speed...But there won't be enough lift for that...so you have to go FASTER than normal wind speed for it to lift.

Haha. This has to be sarcasm.
 
..The plane will keep on attempting flight until such a time as the pilot/co-pilot duo become frustrated to the point that they start drinking all the liquor on board.. At which time they will cease their insane folly of flight & try to taxi back to the tarmack.. The question is,, what happens when they get sideways on the conveyor & the ensueing "head wind" produces lift on the forward edge wing & flips the craft into a barrell roll?? It ain't gonna be pretty, but I wanna be there with a video cam!!!!:D:D
 
seriously

..Plane ain't goin' nowhere.. You must have lift from, not air speed really, but from the movement of air under, & above the wings.. OK,, this is where it gets tricky. Yes, the engines ARE going to produce movement of air, but only through the intake to the turbines. This IS going to produce thrust, but the conveyor will compensate in a negative manner by accelerating the belt speed. Thus, no air transfer over the wings. Remember, the shape of the top of the wing is designed to cause a sort of vacum towards the tailing edge of the wing, producing lift from the top of the wing as much as the angle of the whole wing itself. Example: Yer suckin' through a straw, you's pulls up the liquid through the void in the straw...Movement of matter.. BUT, this movement doesn't cause the whole glass to jerk violently out of yer hands from the intake of the liquid through the straw!
End of story,,,now I can get back to the MAX thread where the really important chit is goin' on..:D:D
 
alright it doesnt matter how fast the conveyor is going the thrust is going to push the plane forward. the power isn't going to the wheels it is using the atmosphere....the wheels are going to spin as fast as the conveyor is moving but the plane will still go forward thus creating lift. sooooo if the plane does not combust due to the fact that the bearings in the wheels aren't able to hold, the plane will take off.

boy do you have a lot to learn about physics

it flies

obviously the wings will shear off when they hit the treadmill posts thus being unable to fly.

OK... If you could get a treadmill without posts, it would fly.:D


People seem to forget that planes move forward because of thrust. The wheels are not powered and basically freewheel. It wouldn't matter if the treadmill were spinning in the opposite direction 50 times faster.

Sounds like if Mythbusters don't screw it up, we will have documented proof soon.:eek:

Yer right bonzo!! I just drug out the vacum,(intake, exhaust, like a jet engine.) stuck the nozzle against the dog's head(he was sleeping) & turned it on..... He shot through the living room like chit shootin' through a goose! Ricocheting off the patio door, rattling the wind chimes outside, finally screeching to a cowering halt underneath the kitchen table..:D:D

I love science.
