AirPlane on a Teardmill and Mythbusters

[oonighttrain]

I'd like to know how long this freakin converyor belt is!

oh.. no one told you??? its really 3 conveyor belts.. 2 for th erear wheels and 1 for the front...

THE THING IS,IT DONT MATTER!! THE CONVEYOR BELT HAS NOTHING TO DO WITH IT!! THE PLANES ENGINES ARE SEPERATE FROM THE WHEELS.. THE WHEELS DONT POWER THE PLANE! THE ENGINES (PROPS/JETS) DO!! THEY ARE PROPELLING AIR!!

..Chit Train!! I didn't realize until this post that you were promoting Shane & Bob!... they take care of folks.

yes they do!! great guys!! ive been using them for 6 years now!!

..Matter of fact, the last ride I went on was with Shane & Bob... we retrieved that 800 summit from the mad. arm last mar. The one the Utah man drowned with..... Sad, sad deal.

bob told me about that when we were there.. sad deal for sure!!!

..Back to business.. The plane flies. The wheels can be turnin' 10 gazillion MPH. & it'll become airborne. & it won't take any longer than from a normal runway. Glad I figured it out before Alex & Jamie air it this week. ( & that red head is a good lookin' old hide, ain't she??)

man, those two idiots are gonna say "the plane doesn't fly, cause we couldn't replicate it." Because they half-a$$ everything they do, and don't use a lot of sound practices to prove out these theories. I understand it, cause they don't have a lot of time for each myth, but still, "you can't robin hood an arrow." Are you fuggin' kidding me?

 

[Sidehiller]

It's possible to prove something is possible, but impossible to prove something is impossible. Think about that one.

I'm glad you said that!

..I've never seen it done, the arrow thing. But I did watch that episode & it left me kinda shakin' my head... all you gotta do is hit the first shaft dead on & it's a kill! Years ago I saw a pic of two civil war era rifle slugs melded together that had collided in mid flight... How do you replicate that??

Engines produce thrust, wind speed over wings produce lift.

Engines produce thrust, wind speed over wings produce lift.

and your point is.....

 

[Mtn Cat 900]

So the speed of the conveyor belts perfectly match the thrust of the engines so that the plane has NO forward movement whatsoever in relationship to the ground, right?
Conveyor belt speed/wheel speed = 300MPH
True ground speed = 0MPH
True airspeed = 0MPH
Speed of air over wings = 0MPH
The airplane has less of a chance of getting airborne than the XP has of winning the "MOST RELIABLE SLED OF THE YEAR" award.

..That's the story I stuck with fer a long time too.. til it hit me like a taco bell wet fart.. Plane flies dewd...

Matching the conveyor speed and the thrust is like matching an orange and a Pat Boone song, one has absolutely NOTHING to do with the other!

ANY thrust, and the plane has forward speed, regardless of what is going on with it's FREEWHEELING wheels.

The plane on the conveyor belt won't fly but if you park one right behind it you might lift it off the ground with the jet wash from the engines of the first jet providing the needed airflow over/under the wings.

 

[sortastock]

..Plane ain't goin' nowhere.. You must have lift from, not air speed really, but from the movement of air under, & above the wings.. OK,, this is where it gets tricky. Yes, the engines ARE going to produce movement of air, but only through the intake to the turbines. This IS going to produce thrust, but the conveyor will compensate in a negative manner by accelerating the belt speed. Thus, no air transfer over the wings. Remember, the shape of the top of the wing is designed to cause a sort of vacum towards the tailing edge of the wing, producing lift from the top of the wing as much as the angle of the whole wing itself. Example: Yer suckin' through a straw, you's pulls up the liquid through the void in the straw...Movement of matter.. BUT, this movement doesn't cause the whole glass to jerk violently out of yer hands from the intake of the liquid through the straw!
End of story,,,now I can get back to the MAX thread where the really important chit is goin' on..

Well boys, this is why some people are not engineers... This is sooooooo simple, I don't understand how some guys here can't understand that the amount of lift generated is NOT a function of wheel speed... 5 year olds understand that this plane will take off... Am I being had- are these guys messing with me?

Okay, I just re-read some of the reply's... and had to fuggin scream...We're hear to help though, so somebody pitch in, how can the following be made more clear:

Lift is INDEPENDENT of wheel speed.

Understanding this will lead you to the correct answer:

The plane takes the fug off.

Yup... Like I said, in a post you obviously overlooked, where I pulled my head out & realized the error of my ways.. The wheels are just wheels in this scenario.. that's all.

ANY thrust, and the plane has forward speed, regardless of what is going on with it's FREEWHEELING wheels.

and you have the magical device that can prove relative motion? You must be a millionaire.

think about it this way, a plane with zero thrust on a conveyor belt will move backwards. A plane on a conveyor belt with thrust = ground speed will have a net movement of zero. A plane on a conveyor belt with thrust > ground speed will move forward creating wind speed over the wing which will create lift.

Thrust directly relates to ground speed. Sure the wheels are "freewheeling" but they have to have some kind of force to drive them forward, right? Or are we sitting here talking about a Harrier jet? Thats the only jet I know of that doesn't need ground speed to develop wind speed to develop lift.

Lift is INDEPENDENT of wheel speed.

read the above.
