Will the plane take off?? Finally going to be answered.***

[RAM_Designs 5,000+ posts]

While I am sure it *may* work, it isn't very pratical.

what "may" work? A normal plane can't take off when it's not moving...ever.

Depends...

Say they drop the plan on the treadmill and both are going 0 mph.

If the treadmill accelerates faster than the plane. the plane will fall off the treadmill.

Just like if you put the treadmill on max speed...if you walk, you will fall off the treadmill. Just like if you put it on slow, you would run over the edge.

That is why I constructed my bet in the way I did. You are going to need a long threadmill to ensure

a) you don't fall off the back

b) you don't run off the edge before you have lift

Well I know that the experiment should work. I thought you were referring to tigerbass' "launching a plane on a treadmill, while it's not moving(the plane).

If the airplane drives on to the tm and the tm is 1/4 mile long, there will be successful flight.

tiger bass you REFUSE to accept the fact that you are iggnorant about how the forces involved interact.

the plane will take off

you seem to think that the plane is coupled directly to the treadmill like a car. when the plane is in fact coupled only in relation. the forward trust applied to a plane is not in relation to the ground, it is in relation to the air. this is where you seem to get confused. because there is a big difference between true and relative groundspeed. and true and realative airspeed. you would know this if you were a pilot

the fact that the treadmill is under the plane makes no difference to the forward trust applied by the planes engine. the treadmill goud be moving at 10x the groundspeed of the plane and the plane would still gain speed. everyone that says the plane won't move because the velocity = 0 is iggnorant to the fact that the plane is not directly coupled to the ground like a car is.. a plane does not need the ground to gain speed. just the air.

ground speed is irelavant to air speed

yup that's right. a planes ground speed doesn't matter only its air speed. this is why in theory if you had a steady 200mph headwind you could have a plane lift of the ground without having any forward volocity in relation to the ground

so to anyone that has no flying experience:

ground speed is irelavant to air speed

air speed is irelavant to ground speed

air sped is what matters

ground speed doesn't mean squat

Fuck........

I've become one of them. A stupid person.

Well, I'm going to go end myself now.

your not stupid, just ignorant. which means you lack the proper knowledge in the subject to be discussing the matter in the manner you are

I take it you figured it out, either through my post or one similar, good for you. The first step to recovery is admitting you have a problem, lol. If it makes you feel any better, your way of originally thinking of it did give me a cool idea. If it worked that way stopping a plane would be awesome. Have it approach a carrier at 700mph. Hit a treadmill going 700mph in the opposite direction. As soon as it hits the planes wheels would simply spin in place at 700mph, no movement. Then simply apply equal braking to the treadmill and wheels. Tell me that doesn't look cool in your head........

I kinda like the arresting hook method better. plus planes don't hit the deck at 700mph. it closer to 150-200 depending on the aircraft. tires would explode if they they had to land at supersonic speeds

 

[Tiger Bass 5,000+ posts]

The forward momentum at those speeds would tear the plane apart if it was stopped that quickly.

You're all arguing your points and I think we all know what's going to happen. They're going to try it probably two or three times, then some huge mechanical error will occur, resulting in a "plausible" prediction.

Looks cool in my head until I actually think about how stupid that is.
