Helicopter on a Turntable
Discussion
So there's a helicopter on a turntable.
The turntable turns at exactly the same speed as the blades but in the opposite direction.
If it doesn't break/fall apart/explode would it take off?
ETA. the tail rotor cannot overpower the turntable.

No, because the lift required for it to take off is generated by the motion of the blades through the air.The turntable turns at exactly the same speed as the blades but in the opposite direction.

In this case the blades would be stationary relative to the air and therefore would generate no lift.

If you assume the helicopter spins with the turntable, no, thats why helicopters on stationary turntables known as helipads don't take off until the blades turn. But the whole point of the great conveyor belt wars was the issue of whether the aircraft moved independently of the belt or whether the belt prevented it gaining airspeed because the pilot had left the brakes on. So expect a dispute about what the helicopter will do. The turntable turns at exactly the same speed as the blades but in the opposite direction.
