The plane moving is what creates lift. For example when I run on treadmill the wind doesn’t blow through my hair.

@JackJames The wheels aren't powering is so the treadmill would have friction but the jets are what actually propel the plane. So i dont see how this wouldnt still fly.
If this was the case, gliders wouldn't be able to take off or any plane on water.

@StevenIzzi the jets would push it forward. Even with jets you have to create lift. That’s the movement of wind over and under the wings. So if you created a giant wind tunnel and under the same circumstances, that would work.

@JackJames Once the engines overcome the gravitational force of the plane. During this phase the wheels move in relation to how fast this force is overcome. To get lift the plane has to move fast enough with forward momentum. Since the conveyer matches the wheels in the opposite direction once we know the force times acceleration of the engine capability to determine if the force is enough to overcome the opposing force
Aka if the engines are capable to move the plane forward against the initial opposing force, yes, it will fly. If not, no.
Remember the wheels are NOT a method of propulsion. For a plane, the wheels only serve to reduce drag against the ground--there would be a lot more friction if the belly of the plane sat on the ground.
This is a kind of basic force vector math problem.
The force of the motor (which pushes against the air) is applied rearward. The rolling resistance of the wheels is an opposing force vector applied opposite the force of the motor. Gravity is a downward vector and the lift provided by the air rushing over the wings is an upward vector.
Gravity and lift are unchanged when comparing the scenarios with and without the conveyor belt.
The force of the motor applied to the air is also unchanged.
The only thing that's changed is that there's now a force vector applied to the wheels in the SAME direction as the direction in which they turn (the conveyor belt). But this has nothing to do with the motor's force vector. It just makes the wheels turn faster.

Absolutely! Conveyor belts are the new frontier!
