A conveyer belt would shorten landing length, though.
Quick question: Can we all agree that if the treadmill speed > wheel speed the plane will never take off?
If there is a hypothetical force keeping the wheel speed (as determined by how fast the wheels are spinning) from never being greater than the treadmill speed, yes, the plane will not move forward.
NO, once again the airplane doesn’t give a flying fuck what it’s wheel speed is, it flies when there is sufficient airflow across the wings to create lift.
Yes, because that can only happen when the speed of all involved parts is 0.
(Unless you have a really strong headwind, then your ground speed can be 0, your treadmill speed can be 0, your wheel speed can be 0, but you still get lift.)
So what is your answer to the question below?
It doesn’t matter if the treadmill is running backwards at the speed of sound. Once the plane applies thrust it moves forward and when the airspeed is sufficient to create lift, the plane flies. PERIOD. That’s it, there is no more.
I don’t see your answer to my question.
You plane is on floats now. Does that help you understand this?
I still don’t see your answer to my question.
You’re trying to make the treadmill speed a function of the speed of the wheels. But in the real world, the wheel speed is a function of the ground/treadmill speed. So in your scenario, what do you believe determines the speed of the wheels?
If you’re maintaining the concept of infinite friction between the wheel and treadmill surface, then how could it be possible for (treadmill speed > wheel speed)?
Your question presupposed violating the laws of physics. At that point, we have no way to guess what you’d see. The treadmill would instantaneously speed up to infinity, the wheels would go just a little bit faster, and the plane would take off.
While the axle is moving forward or backward relative to ground, the wheel speed increases or decreases, respectively, relative to the treadmill speed.
Well, except for the part where the whole kit-n-kaboodle gets turned into a black hole.
In my scenario, the acceleration force of the plane determines the speed of the treadmill through some sort of control system (I gave an analogy of this earlier using sun & planet gears). So the speed of the wheels is ultimately a function of the plane’s thrust.
And what force is causing the axle to move backward relative to the ground?
But my question is based on the assumption that the plane takes off (???). I’m asking what would you see watching the video focused on the wheel/treadmill interaction.
You are asking the question, “what if A+1=A”?
The answer is that that is not a valid mathematical formulation.
And you keep asking, “well, what if it is, what then?”
In the simplified, ideal scenario, nothing. In the closer-to-real-world scenario, friction.
