Let's say hypothetically you have an airplane on a conveyor belt

45 posts in this topic

And due to some mechanism or whatever you can make the belt act like a treadmill and have it go the same speed as the forward velocity of the airplane (in an attempt to "cancel out" the velocity) ... Would the plane be able to take off?

Is it in a vacuum and what color is the Plane?

What is the tire pressure of the LH tire?

Hello,

Yes it would take off. It doesn't matter how fast the conveyor belt moves, the aircrafts forward velocity is unrelated to the velocity of the belt. None of the aircrafts velocity is obtained from its wheels as they are all free spinning and not powered. The only real consideration would be is the belts overall length longer than the takeoff run of the aircraft in question?

Well the wheels might spin so fast that they break down and the plane crashes and burns before it can achieve take off speed. :D Otherwise, yes, the plane will take off, as the wheels do not provide any forward motion, they spin in freewheel.

But if the backward speed of the belt = the forward speed of the airplane, then the absolute forward speed of the airplane has to be zero, so it can not ever take off.

If the brakes are on, and you are using the speed of the treadmill to move the plane forward in order to achieve lift... you're gonna need a huge treadmill capable of moving a plane about 200 plus MPH, at least. Unless it's a bi-winged jobber or glider.

Really man... why waste time with treadmills?

Why not use gravity swings that use parabolic motion to slingshot planes and ships into flying?

Or elastics?!?

Hey, at least I'm not sitting here trying to negate "forward velocity" by sticking a plane on a treadmill.

sheesh

I hate to burst everyones bubble but that airplane is going nowhere if it doesn't get off the treadmill.
