You would need to revisit the second law, every action there is an equal and opposite reaction. Conver move one wheels spin other way, thrust is created on way, a resultant force is seen the other way. Ps, bernouli’s principal does not create enough lift to make a plane fly, it is a resulatant of the wind striking the underside of the wing, if the angle of attack on the wing of a piper cub would be zero it would take a relative speed of 250mph for it to take of. It will take off, engineering principles say so.
Read the articile Damn second law, leave Mr. Bernoulli alone
we actually discussed this last night in my HVAC since my teacher also teaches fluid mechanics and thermo fluids lab
The conveyor belt doesnt mean shit, because the wheels don’t mean shit when it comes to the plane taking off. The only difference is the wheels are going to spin twice as fast when the plan takes off.
i think itll still take off without a problem, but it might take a bit more thrust as a result of moving at a slightly slower speed due to bearing friction in the landing gear.
thats the thing it will move, if there is thrust acting on the air behind the plane, the is a resultant force pushing the place foward. The treamill has nothing to do with it. the tradmill is basically there to give a normal force so the plane would not fall. put a skatebord on a treadmill, now hold it in place, no movement, now put a force against the top of the bored, the bored its self will move foward, same concept.
Hmmm… the plane is moved by pushing air. The wheels just spin double speed. The air is what pushes the plane… not the wheels. I think I see what you are getting at now.
I didn’t read the whole thing because I am sure its filled with…whatever…but the plane won’t have any air moving over its wings to help provide lift. The engines simply provide thrust which moves the air over the wings fast enough to facilitate lift. Since the plane isn’t moving through the air, no lift.
