I don't think plane can take off from conveyor belt. Because according to bernoulli's principle Air air molecules need to flow around the wings to create lifting force. Even plane move fast enough on conveyor belt. Plane speed so slow relatively surrounded air. Because if plane move on run way plane go through the air molecules. But in this case plane engine suck surrounded air in to the engine and pushed from back. It create force to move plane forward but not lifting force on the wings. This is the way I think this question. Please tell me if I wrong.

Hmm, I always thought that with this one the plane could take off but the logic in the question means it just cant actually move initially, so its the semantics of the question but the bulk of actual the physics around the scenario means that it would take off it we substitute ground speed, got it now thanks. The conveyor wont actually let the plane move. I think a lot of folk get this right but for the wrong reason.

If the aircraft had zero-friction & indestructible wheels it would takeoff normally as the conveyor belt has no means to product an opposite force on the aircraft. However, if you don't have the aforementioned wheels then the wheels would be destroyed on the takeoff attempt.

No, the plane cannot takeoff if it was on a conveyor belt because it will snap the conveyor belt. If the conveyor belt got upgraded to handle more weight, it wouldn’t be able to have fast speed.

Actually the question as posed -- conveyor belt designed to match the speed of the wheels -- I think the answer is no. Yes there's thrust and the engines don't care about the wheels, but lets say the airplane starts to accelerate forward. The wheels spin faster so the conveyor belt is designed to spin faster with it keeping the plane still. No matter how much thrust the engines generate, if the conveyor is designed to match the speed of the wheels all the engines should be doing in effect is accelerating the wheels until they basically explode (or the conveyor belt does assuming it does what it's claimed to do per the original intent). The plane cannot take off without air flowing over the wings and that won't happen if the conveyor belt always matches the speed of the wheels.

this came up at work some 3 years ago i my answer has not changed. My answer is no it will not take off and the reason id the tyres will fail from overspeed before the plane has moved very far, the reason is as soon as you start to move the plane is say moving at 1m per second then the conveyor will match this but that will now make the wheels do 2m per second and so on in a runaway feedback loop till the tyres tear apart and then the plane is going nowhere

Theoretically it MAY work, but, the problem is that for a plane to “run” in place until it “gets” to speed, there is not enough airflow on the wings to lift it. Practically speaking, it is impossible to build a conveyer belt of that size to move that fast while having enough support for the weight of the plane.....actually, if it is possible for the plane to build enough thrust, and the conveyer belt can suddenly accelerate, without delay, to the take off speed of the plane, then it will allow the plane to take off at much shorter distance....kind of like how jet fighter on aircraft carriers....but I feel sorry for anyone on board....

I think it will still take off because the whole point of long runways is to buy time for the plane to pick up speed and it will still do the same thing if the runway is 'spinning".

Ok so here is my take on the whole thing. (I’m absolutely *not* confident about my answer XD) I think at the beginning, the engines spool up and the plane starts to move, so does the belt. The plane while behave like a car on a dyno (a test stand if you will). But I think, because the power is provided by the engine and not the wheels, at some point the thrust will be to great for the wheels to be kept on the belt and the plane will skip over the conveyor belt. But it will not take of as there is no air movement around the wings and therefore no lift.

No, it won't takeoff because there won't be any wind coming from the opposite direction that generates lift as the plane is at the same position

They actually did this on Mythbusters. Great episode. If it was a car. It wouldn't go anywhere. But it's not a car, it's a plane and the wheels have nothing to do with moving the plane. You'd need a wind tunnel instead to be your "conveyor". Then you could maybe stall the wings

I think the plane in the first example *might* still take off, if you take friction into account: If the conveyor belt has any friction at all, at some speed it would take enough air with it to "blow" onto the plane, increasing air speed, thus the wheels won't be needed anymore. If it didn't have friction (to avoid this scenario), the wheels wouldn't have any friction there either, so the plane could take off just sliding instead
Brown7219 6 uur geleden
What if the brakes were applied and the conveyor run in the opposite direction? What would this mean for ground speed vs airspeed? Would the airflow generate lift as normal, enabling take-off?
Rapunzel 1701
Rapunzel 1701 6 uur geleden
Sorry Joe, answer #1 is wrong. You would just have the wheels spinning at 2X airspeed. Wheel/ground speed & direction is irrelevant. You even state this directly at 6:55. Unless the trick answer is that friction overcomes thrust, but you would need far more than 2x speed on the belt.

Hey Captain Joe, I would really appreciate a video on why you shouldn't be afraid of flying. I know a lot of data and sources already exist that prove that flying is safer than even walking up a flight of stairs, but some people can't fathom the idea that cruising at 35,000 feet above the ground is actually safer than walking up or down a flight of stairs and driving on the road. There are a lot of videos on NLfast about this topic but someone of your image would be able to make a real impact in reassuring scared flyers.

Thrust + airfoil of wing(airflow) = Lift. Take away the airflow because it’s stationary. I’d say it won’t create lift.

The wheels themselves in the first scenario would have to roll really really fast to produce an enormous amount of drag 🤣 the drag created from the wheels turning, would have to be equal to the thrust 😅

I can't believe this is even a question. It's like asking if a car will drive forward if the headlights are facing backwards. The wheels have nothing to do with what makes the plane accelerate or fly.
Pablo Gonzalez

Joe you're overthinking it man. The wheels freewheel. They can spin backwards, forwards or not at all they don't affect the thrust acting against the air. The aircraft takes off either way what changes is the wheel rpm.

I just get started to watch it on 1:00. And the answer is definitely no. Aircraft need the lift and drag force to take off.

Beg to differ. If the conveyor belt works against the wheels the WHEELS would be standing still. That would mean the conveyor belt moves forward in the same direction as the thrust. Your graphic at 2:58 shows the conveyor belt to move in opposite direction. This won't stop the wheels, but instead make them turn at double speed. So with a Vr of 150knts the wheels would be turning 300knts. You may now a tire, but taking of is no problem. No need for infinite speed.
