Plane on a treadmill poll...

[Hulud]

it will take off
lets close this cause i need a good laugh

[{X}Echo419]

Echo never called or anything else...offer still stands for those who refuse to believe

sry, I was busy as hell this weekend and I didn't want to call you and be like, "ell, umm. I donno. let me call you back."
so, I'll ttyl. sry

Model airplane expieriment is not worth the trouble anyways.. it may visually help some people see the concept but not prove anything really.

[StupidBikerBoy]

This things still goin?

[speedminded]

This things still goin?

yep, some people can't quite think outside the box.

[speedminded]

*bump* What's the verdict?

[joecoolfreak]

Oh lord..not this again *sighs*

[wantboost]

If the treadmill creates a current then no.

[StupidBikerBoy]

*bump* What's the verdict?

LMAO

you love this shit don't you?

[Flip]

LOL, ITS OVER!!!!!! NO MORE!!!!

Snakes on a plane on a treadmill...the sequal.

[The Golden Child]

wasnt there a thread like this awhile back ??

[97prelude]

No... backwards and forwards movement = the plane is standing still, even though the wheels are moving. Planes count on airflow to get lift.... you don't feel a breeze when you run on a treadmill.. therefore, no lift = no flying.

It doesnt matter. the wheels are independent from everything else. The wheels will just move at the normal takeoff speed of the plane+the speed of the treadmill. the plane will use up just as much of the conveyor as it would a runway. its an easy concept, if u dont understand it, then u probably dont have much goin on up top.

[Vteckidd]

yes

[ScreaminZetec]

no, your wrong. the plane doesnt have to overcome anything. the plane will take off as it would normally. the wheels would just be spinning really fast.

right but it still needs airflow over the wings to create lift. So it either needs a very strong head wind or it need forward movement. And the reason a plane takes off on an aircraft carrier is the cat as well as the carrier steamin at 20 knots into the wind which createst the airflow over the wing. So the plane does need the movement to generate life. Cause if it's stationary on the treadmill and just rolling on its wheels that doesnt creat life as there is no airflow over the wings.

Right, but the treadmill WOULD NOT stop the forward movement of the plane. The plane would take off like it normally would on a standard runway...this runway, however, would just happen to be a treadmill. It would still take off.

Again, being on a threadmill/conveyor has ZERO effect on anything except the speed of the wheels while it is accelerating then taking off. It will act NO differantly than every single other runway in the world.

A treadmill or conveyor in no way what so ever will prevent the forward movement of an aircraft. period.

I agree 100%, thats what I was getting at, I just didnt state it clearly.

[speedminded]

BUMPPPPPP

[joecoolfreak]

The plane can't take off

[speedminded]

The plane can't take off

He never showed did he?

[joecoolfreak]

Nope =-)

[joecoolfreak]

He never showed did he?

Of course not

[speedminded]

Just instigating...

i already edited

[speedminded]

Well can it take off?!

[joecoolfreak]

only if the auto-pilot is engaged...

[Kyle]

Well we don't even know what speed the plane is traveling at.

[joecoolfreak]

Well we don't even know what speed the plane is traveling at.

And it wouldn't matter.

[Mike Lowrey]

Answer = No.

[man]

Well we don't even know what speed the plane is traveling at.

Just say yes and move on...

[buffdaddy18]

oh my god....... I can't believe this thing got brought back up.


YES IT WILL FREAKING TAKE OFF!

/thread

[Calvin200sx]

Hopefully this will clear up all discussion.

There are four forces that govern an airplane at any given time: lift, weight, thrust and drag. Lift and weight oppose each other but can be disregarded in this question because all we are talking about it whether or not the airplane can accelerate in reference to the surrounding air. Once we get acceleration and airflow we can get the lift and weight but we don't need to talk about that now.

The throttle of the airplane is advanced and propeller/jet of the airplane produces thrust. We now have a forward vector, say 500 pounds of force, for a small cessna. In order for the plane to remain stationary an equal and opposite force needs to be introduced. Everybody follow? This opposite force would be drag.

We need to account for 500 pounds of drag. Right now the only drag is the force of friction in the wheel bearing. Has anyone here ever tried to push a cessna? It's not very hard...maybe 50 pounds of force at the most. So now we have 450 pounds of force acting in the forward direction. The conveyor belt itself does not impart any friction or drag to the airplane. It will accelerate, gain airspeed, and take off

Let's think of it a different way. Let's say the plane is landing. It approaches the runway at 100 knots and is 1 foot above the ground. As posed in the original question the conveyor belt is moving in an equal and opposite direction. So it's moving 100 knots backwards. As soon as the plane touches down, what happens? nothing...it continues its rollout as if the runway were stationary. It doesn't just automatically come to a stop. The airspeed indicator of the plane would read 100 but the wheel speed would be 200. (apologies to Youens at flightinfo.com)

People cannot separate a car/bike/walking on a treadmill with an airplane. Same thing would happen if you put the airplane on ice and hit the throttle, it will still accelerate at the exact same rate as on a runway (not a safe operation however). Try that with a car/bike/your foot and you'll get drastically different results."

All that matters is if there are any snakes on this plane.

[santacruz77]

no but a helicopter will :boobies:

[man]

no but a helicopter will :boobies:

Why are people still fighting this?

[StupidBikerBoy]

Oh god

[Kyle]

All that matters is if there are any snakes on this plane.

I was actually thinking about that, I was like hey this thread could use a snakes on a plane post...

[JoeyKazez]

Ok heres what i think. I don't know if anyone else already posted something similar to this but thats way too much work to find out. I think that it would, because planes do not use the power too their wheels (much) during takoff, The thrust from the plane would push it along, and make it go at a normal speed. Imagine someone on rollerskates on a treadmill, they would be able to pretty much stay in place, but if someone pushed them, no matter how fast the treadmill went it would still push the person forward, since there is not much friction on the wheels.
