Plane Conveyor Belt Mythbusters Bigger Plane Scene

[lceus]

Isn't it possible that the wheels themselves created drag, but by removing that drag on the wheels you can get up to speed and gain lift? This idea needs an engine to be on though.

Another equally redundant experiment they did is whether a helicopter can fly if its mounted on a flat surface.

[byakumaruZ]

The reason is the plane doesn't accelerate using the wheels that are supposed to be holding onto the ground, like cars. It uses the propeller to create thrust which isn't affected by whatever goes on underneath the wheels.

Since the wheels aren't attached to any motors that help with the moving, all they do is... maybe, spin twice as fast?

[Bman00]

Well he was moving forward which creates lift. The wheels do nothing for a plane but create the movement they need to create wind against the flaps/wings; just like the wind you feel when you ride your bike very quickly. move forward and brake, (which might be debatable with reverse-thrusters.) Stupid experiment.

[samugrose]

seriously.. this does not change a thing. if this experiment had worked as the mythbusters described it, which it did not, then the plane would roll in place, not taking off, due to no air coursing over the wings leading to take off.

[Conflab]

@samugrose no, you misunderstand the whole point.

the myth is that the plane would stay in place; it doesn't because the wheels are free spinning. It makes little difference what speed the ground is going because the planes velocity comes from pushing air, not from pushing against the ground.

[samugrose]

@Conflab so i'm to understand that the entire myth was essentially about a few wheels moving in time with a treadmill? and i'm aware that the plane does not "push against the ground." i never even implied that. the only thing i mentioned regarding the plane's takeoff was air coursing over the plane's wings, which IS the only reason planes take off in the first place. this whole myth is just retarded.

[CaptSly]

I thought the nose gear was supposed to touch the pavement after the mains....

[TonyAirlines]

That would usually result in the nose wheel breaking off from the pressure.

[RobGatzke]

Wasn't the plane supposed to take off from where it was sitting? I thought that was the point.

[hugecool]

No, the point is that some people think that the treadmill can stop the plane from moving forward, leading to it not taking off

[taledarkside]

@RobGatzke

It is the point. If you watch the "ENTIRE" episode, mythbuster claimed it was going to stay still and they would see if it would take off.

The first experiment, the plane never took off. So they cheated and make a really large tarp. defeats the myth

[iNfx1]

2:31 for anyone that wants to skip the crap.

[kevc015]

What? I don't get it.

The plane's wheels were moving faster than the conveyor belt. You can see that when the plane, when still on the ground, are moving past the cones.

New experimental design please?

[speedstriker]

Well, Mark is one brave man to volunteer for this stunt. Good one!

[pilotnerd101]

HAHAHAHAHA watch at 2:35. Adams segway rolls away. i laugh really hard for some reason everytime i see that. its a ghost!!!! or computers. or a ghost!!!!!

[pilotnerd101]

what kind of plane was that?!?!? i want one. what does it cost, 80K? if its 100K i will just step up to a cessna 162

[shaighai]

Ufffffffff - they are truely suprised by the result ?????????

How much dumber can they get?????

I would instantly revoke this pilot's flight license for beeing this stupid.

Idea for next stunt:

"Jamie, do you think the plane could take off if we two blow in the opposite direction??? whoa, i'm sooooooooooooooooo suprised what will happen!!!!!"

[ways2die]

I don't understand how they could think they wouln't get off the ground. I would think that even if the tarp was moving before the plane, the plane could still take off. I don't under stand science all that much but thats be where my logic says 'come on it will still lift up'.

[mitchio83]

They were not suprised. They attempted to explain why the aiplane would take off through the whole episode.

[wackowillie]

Thats so wrong....

Tne plane was going so much faster then the tarp and truck was!

[khryzalids]

it doesnt matter if the truck was going slower or faster...because the plane its not getting speed by its wheels...

[Bobby61557]

I dont know what the mystery is The prop propells the plane forward not the wheels so the winf off the prop would still go under the wings moving or not moving surface shouldnt have been a factor

[smcudb]

wow guess they never heard of lift and the plane is rolling at the start what a joke hay i have one ...melt steel with karosene and paper theres a myth that need to be busted ..WAKE UP PEOPLE

[NRen2k5]

@smcudb lol, let me guess - you're a 9/11 "Truther"? Somebody needs a life....

[Smartathanyou]

uh...duuuuhhh
