Question:
If an aeroplane is taking off but is on a conveyor belt that is moving at the same speed as the plane, would the plane take off?
Just would like to see peoples responses
Its a question to get everyones minds thinking for once

Its nothing to do with the wheels as the wheels arent powered

The answer is that it would work
Clue - how does an aeroplane produce thrust?
Clue - how does an aeroplane acheive lift?

It would only take off if it lifted off the conveyor - if it's stuck to the conveyer and hence forced backwards as hard as it is pushing and forwards and therefore stationary - then there would be no air going under the wings to produce the lift.
however if it's sitting on the conveyor and the engines are at full speed and it detaches from the conveyor at all it may get the speed then needed to lift off - hence the same way a plane can use its jet engines at full speed to pull up high into the sky at take off

lol just what I thought Surely if just the engine's were enough to lift the plane without any actual movement forward (to get air under the wings) - then the plane should be able to sit on the run way, apply brakes and full thrust - release brakes and take off straight away. Which doesn't happen.

what?? no mate. The aircraft is effectively stationary, it has no forward motion, there is no airflow over the wings, it cannot take off.

FLMAO the engines only provide forward motion. even at full power, if the conveyor belt is negating the forward movement, the aircraft is stationary. an aircraft ONLY flies when it has a pressure difference between the upper and lower wing great enough to produce lift. Bernoullis principle

Of course it will take off
It has jet engines ffs, the engines produce thrust through the air not the conveyor belt.
The contact between the wheels and road is irrelevant

I see what jules is saying - the plane would still move forward?
