Principles of flight?

[Bridget]

I'd be keen for an experiment

[Brick]

argueing on the internet is like the special olympics, even if you win your still a retard

its not really arguing, its more of a debate

yea or that
id say as soon as get gets to wat ever speed it needs to to get enough lift to rise it will, but as soon as its lost that help from the belt it wud lose to much speed and fall down after 2 seconds

[ollieboy]

I can't believe I waded through three pages of this sh*t

There is only one *one* 1 way to know for sure

And that is a pratical experiment

I'm keen if you are

Im keen as well

[no_8wire]

if there was no friction in the wheels then the plane should sit there at 0 km/h ground speed. the plane could then accelerate up to take off speed.

i guess this question depends what variables you want to include.

yes it could accelerate its take off speed. however it still wouldnt be moving and therefore not creating any lift force/ real air speed...therefore its supposed "takeoff" speed would be non exsistant...

no no no... the ground speed and air speed would both be 0.

it then accelerates to lift off velocity. and walla... take off

and what ever take off velocity was, double that and thats the velovity of the surface of the wheels of the aircraft.

Its lift off velocity is depedant on the amount of air/speed of air under wings.
If the plane is not moving as its velocity on the belt is "0" effectivly( speed plane-speed belt = 0).

There is no way therefore that the plane could reach a speed to take off, as no matter what speed it was it still wouldnt be moving, and there would be no air movement to creat lift.

I prefer to think of it as discusing theory....

[Bridget]

well I give up, lol

Seriously man

All I have seen so far is "it will/won't take off because my website/text book told me so!"

Allthough, it would probably be very difficult to actually do in real life

I dont want to sound like a penis but just to correct that the lift is dependant on the air above the wings believe it or not.

[Bridget]

Very difficult to do in real life... but I think someone should at least try it the a toy plane... haha

[no_8wire]

so fivebob what is YOUR answer?

[V8MOFO]

lets see now, The whole point of the travelator is that the plane doesn't move. Otherwise there is no point to the question.
I think what you are missing, is that this is a physics question on how lift works, not a question on how planes work.
Like I said before, engines dont blow air over wings, they counter drag.

Now, the plane is not moving relative to the air. Here is a little equation to work out the lift.


Without air velocity there is no lift. You can give it all the thrust you want in horizontal direction but it simply wont fly.[/img]

YAH some one UNDERSTANDS!!!!!!!!!!

come one, thats what I was trying to say ages ago.

Sorry I should have completed the sentance...dependant on the difference of velocity between the air flow over& under the wing

ooh nom you joined the dark side.

[Bridget]

I declare I don't care no more, I'm burning up and out and growing bored... lol *sigh* this is crap I don't want to think about it anymore.

okay then WE understand! ( OB, N8, V8 )

Cool, Hey I double posted when I was correcting a spelling mistake

[no_8wire]

which time?
