PLEASE !!!

Someone can say me what the man is saying ?

It's very important.

Thanks

[inDoKid101]

the man is saying on how the plane takeoff

it all depend on plane wieght

i hope your happy for stealing this vid :)

[pikemaster92]

you know. I hate people who ''steal'' vids from someone who has worked on it for AGES and these people who stole it act like they made it and take all credit for it. THIS video belongs to Spice1. It's his video and i hate people who steal it.

to me, seeing 400 tonnes in flight is a testament to human ingenuity. love it.

It is true that the faster flowing air generates less pressure than slower flowing air. However, if you're not correctly informed, you are misleaded by this video and in that sense, it's incorrect.

the video isn't wrong, its just simplified

the Kutta-condition dictates that the trailing edge of the wing must be a sharp point, but it doesn't prove the video wrong

[Coolboybadboy]

The normal airpressure under the wing lifts into this partial vaacum, which enables the airplane to fly.

(By the way, the 4. point is the Bernoulli law.)

4: when the airplane is in motion, air rushes past the wing. The air passing the upper surface moves a longer distance in the same time as the air passing the lower surface. And therefore moves past the upper surface faster. This difference in airspeed increases as the airplane itself moves faster, and creates a partial vaacum along the upper wing surface.

Well let's see, what the man telling in the vid. Not sure that I understand well, i'm a bit poor in english...

1: All ordinary aircraft must have forward speed to fly.

2: Unintelligible for me :(

3: ..... the wing has been designed it so, that its upper surface is more curved than its lower surface.
