If an AIRPLANE is on a TREADMILL will it take off? (Physics)

[chroneos]

Well what say you misc?

[Redfish225]

No, who was lift?

[McDoubles]

yeah because thats how i take off

















notsrs

[chlaxman]

Yes. Airplanes don't generate forward velocity through the wheels.

[RS8]

nope. the wheels would spin, but there is no moving air around the plane to create a pressure differential for it to take flight

bunch of fukin aeronautical engineers above me

[chroneos]

Yes. Airplanes don't generate forward velocity through the wheels.

Seems to be some disagreement...

[peacebraah]

Only if you have a super long treadmill and the plane starts moving forward

Of course it would.. Lol tall are ****ing retarded

ouch, first victim

The moving air is caused by the engine/propeller, not the wheels.

oh here we ****ing go again with this thread

[NoobGains23]

Well what say you misc?

Assuming the treadmill has a maximum speed (which all do) then yes the plane will take off.
The planes jet engines will create more thrust than the treadmill can create backwards speed, as a result the thrust will be more than the reverse roll caused by the treadmill. The plane will struggle but will eventually take off by going forwards faster than the treadmill can pull it backwards

[ErnieMccracken]

Need to put a giant fan in front of the treadmill.

[chlaxman]

Seems to be some disagreement...

That's because peoplethink of their cars. That's not how a plane generates horizontal velocity.

[jwlee7ucla]

motorless airplanes glide in the sky.

motorful airplanes fly in the sky.

motor = lift?

but what was missing wheels?

[xavengedx23]

due to Bernoulli's principle.

Fukc this *******

[stressedpotato]

Yes. Airplanes don't generate forward velocity through the wheels.

This. The wheels can spin as fast as they want the wrong way but the thrust comes from the engines.

Then who was harrier?

[ironicinori]

Itt *******s don't know how plane engines work. Short answer is yes it will take off. A plane on a treadmill WILL NOT BE MOVING IN PLACE. So it will have to be a long ass treadmill, and won't look as cool as you think it will.


































They literally did it with a real airplane on Mythbusters, I don't have to be an aerospace engineer to be smarter than you simpletons.

[IPoopStandingUp]

I tried this once but instead of an airplane i used my wheelchair bound cousin.

the results werent very good

[woofermazing]

Wheels don't move airplanes, thrust from the engine moves the plane forward.

And if you had some super special treadmill that was able to always match the speed of the wheels, the wheels would get ripped off at a critical angular velocity before stopping the plane from moving forward.

I love this thread, and I love trouncing people that say it won't take off in them.

The thrust of the engines is independent of the wheels. The thrust will move the plane forward regardless of treadmill speed. The plane moving forward (from the thrust) will create flow over the wings, which will create lift, allowing the plane to take off.

I have a degree in aerospace engineering, so suck it.

[MusicProducer]

Wait, is the airplane holding onto the handlebars of the treadmill?

[NoobGains23]

It really depends on what type of treadmill.

In this hypothetical scenario of a giant treadmill, we assume that the treadmill will move as fast as the plane does, so the plane remains stationary and will never achieve lift.

This. I get why people think it will take off (the thrust comes from air being blasted out of the jet engines) but as long as the treadmill meets the speed of the airplane, it will never take off.
A plane still needs a lot of air to travel under the wings for it to achieve lift, which it can only do by moving forward (or a huge wind blowing in the opposite direction, which the treadmill cant create).

A better question would be, 'Would a plane take off if there was a fan facing it, blowing the same volume of air as the jet engines can produce thrust'. The answer is yes, but it wouldn't move forward, but it would lift off the ground.

arent we assuming the plane is stationary in regards to the environment??

This is some subtle trolling. Well done.

Yeah but they didn't use a real plane and a real huge treadmill, not sure what to believe.

The riddle has always been that the treadmill always matches the same opposite speed as the plane achieves. So where does this airflow over the wings come from?
