Come on guys, its been beaten to death already. We are all going to believe what we want to believe; no amount of convincing is going to change anyone's mind anymore...

 

LOL that is a good one , of course the plane will fly, it does not get it thrust from the wheels of the airplane , it comes from either the prop or thrust of the engine. I myself have taken off into the air with zero ground speed once in the Piper cub , only because off 55 mph wind right down the runway and the help of 6 guys keeping the airplane on the ground till I added T.O. power and had them let go of the aircraft and had zero ground movement. if the wind had been anymore then that I dont know that I would have done that because I would have been flying backward then , but it was one heck of a experience.

 

You know what I find most interesting about this thread is when people get huffy about the difference of opinion that we have .... and yet they keep coming back to read more Get a grip ... it is a FRIENDLY discussion, not WWIII.

It is a GREAT test to check people's communication skills. Some are eloquent articulators .... and some are wrench throwers. Some of us are having fun ribbing our DTR friends and others seem to get their pride stepped on .
Life is too short to get your panties in a wad. Just enjoy it until you get tired of it ... and then move on .

PISTOL

 

shut up butt-head

 

... chalk one up for the wrench throwers .

i was gonna come up with some super-witty remark, but i have nothing

 

You two kids keep up like that and I will make you sit on the couch AND HOLD HANDS for a hour!! (That was pure torture when my mother did that to me and my siblings)

 

I hereby eat my words....gulp........The Dang Plane WILL fly. I should have gone back and read the original post before stickin my foot in my mouth.

 

no, Mr. Jackson, that would be "bad"-touching

 

Friction is the only thing keeping the plane from flying. The planes tire must move faster than the belt for the plane to gain ground speed.

Picture a plane on the moving runway. The engine is just above idle. The tires and runway are moving at the same speed and the plane is motionless. The throttle is pushed to the stop. The prop or jet keeps making more and more thrust and the runway moves faster and faster matching the speed of the tires. Something has to give. When the plane makes enough thrust the tires will lose traction with the runway and slide. When this happens the plane is moving in relation to the ground. The engine is making full power and pushing the tires down the moving runway. We all know the tires would blow and the plane would not take off. But since the question was so vague and what if, my tires would hold up. As long as the plane could make enough thrust to overcome the tires traction and fricton with the runway it would fly.

Could any of this ever happen? No.

Is it pointless to argue on the internet? Yes

 

Why are the brakes on?

 

7.8345 MPH .... yup i came up with that anwser all by myself.... lol ... yes you can throw used parts at me now


Dangousity

 

If I understand the question correctly I think that the plane would take off but if the plane developed lift at 50 mph on the ground it would need to go 100 mph on the conveyor to develop the same amout of lift.

 

the conveyor belt would go 100 mph in the other direction and forward movement would cease.

 

Ahhhhhhhhhhh just re-read it. The trick is that it's a VTOL plane like a harrier
