brainlet here. Will the plane take off if its moving on a treadmill?

bend over a bit, I use to do it too, just try to create distance

no

no because friction with the air is needed

Yeah. The jets push air back causing the plane to move forward. Once there's enough air hitting the wings, you have lift. The wheels don't create force really.

yes. it is the jet engines that provide the propulsion, not the wheels. the treadmill wouldn't stop the plane from accelerating. the wheels would just spin faster than if it was on a normal surface.

The net force driving the plane forward is 0 if the treadmill moves fast enough to keep the plane stationary, so the plane will never be able to take off because it has 0 momentum, velocity, and acceleration. Like asking if your car will ever drive down a perfectly flat street while geared in neutral.

Google it faggots

fucking brainlets don't realize that the engines propel the plane and not the wheels

no lift is produced because the plane isnt actually moving it will not take off because it is not interacting with any air molecules.

This poster is correct

So what happens if the conveyor belt matches the speed the engines can pull it?

You can negate the conveyor belt. The engines propel the plane forward, just like they do during flight.

This is the basic conflict that we need to know about before we can determine before we can answer the question.
The people who simply say "UH YES BECAUSE ENGINES" are acting like if the engines were off the plane would sit in 1 place when the belt is on. It would not, it would get thrown off the back of the treadmill.

The treadmill moving will make it more difficult for it to take off. And could lead us to a situation where our engines can't pull us forward fast enough to create the airspeed needed to generate enough lift to get us off the ground.
This is more important with a /model airplane/ where the wheels are often of a construction where rolling causes a significant amount of friction and slows the plane a lot more than a real commercial jet. An actual jet can produce way way more thrust than actually required to get off the ground normally, and friction from wheels rolling is minimal. So an actual jet could most assuredly take off of some sort of GIANT conveyor belt. A model plane sitting on a treadmill like the actual OP's image depicts might not be able to, if it's already at full thrust and struggles to get the required airspeed for sufficient lift, as many models do. Or you might need to grease the axles that the wheels sit on just to make sure it does.

So if the belt and engine start at zero and accelerate up to same speed (in engine terms the engine accelerates to max rpm) and match at the engine's max output even if there's no relative wind the plane will still takeoff?

Would the aircraft still have the same takeoff distance if it was on a conveyor belt?

If you assume there is no friction, the plane will still take off. Wind speed matters but it doesn't matter as much once the plane has enough velocity to generate lift.

I see what you're saying, the wheels will spin at a higher speed but they're designed to create low friction so even if you're at max thrust you can still pull forward (if your wheels are good enough I assume).
