Will it take off?

that ^ and.....

There really should be an emoticon for beating your head against a dead horse.

Or a dead pilot. []

Oh the inanity!!!? Oh the restraint I shall impose upon myself in response.

[oldenough]

Are there still people here who believe it won't take off???.....[:'(]

Yes. She can see Russia from her kitchen sink.

I can't believe this thread is still around.[:|]

Yes the plane flies, its free wheeling wheel speed does not affect its flight, end of [a long] story.

[ZAKO]

And a kite flies without wheels

[germerikan]

ah but what if it was laying on a treadmill??

And a kite flies without wheels

[ZAKO]

I use the tredmill,,,Puff Puff !!!!!

[Coytee]

It's been a while... I wonder if with the passage of some time and perhaps some new faces, we have any new clarification?

[ZAKO]

And the International Space Station can fly without Air.. But its in constant freefall..

[BigStewMan]

flight? Impossible. it's a cheap trick done with mirrors.

[Mongo171]

flight? Impossible. it's a cheap trick done with mirrors.

And smoke...don't forget the smoke!

Which I means when the conveyor kicks on, immediately before forward thrust is applied, the aircraft just sits motionless and free-wheeling atop the conveyor, because it has magical frictionless tires and wheel bearings. Simply magical the way that works.

Q: If you did a transplant, and replaced the jet engines with Boomzilla's Cornwall III speakers, would the plane still take off?

A: No way, because both speaker boxes have had such severe corner drops they can no longer perform as designed, and then he tries to impugn Klipsch![6]

Observation: He would still try to sell the jet as an as designed Boing F18, tho.

Thrust should be applied and carefully timed to the treadmill by the pilot so the plane would not lose too much ground when the treadmill starts up, just as a person walking/running on a treadmill must time himself to the motion of a treadmill.

However shortly afterward the wheels would become freewheeling to the speed of the treadmill, while the planes propeller or jet engine would pull the plane through the air and into flight.

The answer is stll, and always, YES.

So if these poor wheels can never keep up with these mighty and powerful airframes, how come all these planes don't gyrate wildly and flip over when they land?At some point airframe speed and wheel speed are going to be the same before the plane takes off, because the purpose of the idler wheels with low friction bearings is to allow the support structure to move at the same speed as the airframe, enabling it to take flight. If the wheels do not make it, they'll get left behind. []

Looking back at the original question, they never mention the wheels... they say this.. the conveyor has a system that tracks the speed of the plane and matches it exactly in the opposite direction. The wheels are a red herring.

The airframe has exactly zero relative speed at all times, no net distance displacement, and no lift, because it is effectively parked at the flag placed at its nose.

Now you can do all sorts of tricks with the conveyor, or have both freefalling in air, etc., but if you set the flag at the plane nose on the ground, and the F-18 nose does not pass the flag on the ground, it won't take off. []

The wheels are what the conveyor contacts they are not as you put it a red herring. The conveyor has very little affect on the plane and after a certain point even if the conveyor is travelling many times the planes speed in the opposite direction it will not move the plane or prevent the planes movement or flight. Because plane wheels are freewheeling and do not create the planes excelleration which is done only by air and either the planes propeller or jet motor, the conveyor cannot prevent the plane from moving.

You are the one who misunderstands the original question and writing something into it which simply is not there, in other words if the plane can never move no matter what will it move? obviously no, but this is not the question and the conveyor is not capable of preventing the plane from either moving or flying.
