props and wings are basicaly the same thing, a aerofoil moving though air causing lift... so.. why on props is the thrust, or the amount of air being passed though considered important, when with wings, any downdraft is argued to be unimportant and that the lift is caused by the high pressure below VS the low pressure above is what creates the lift. shouldnt it be the same for both?, or is the air blown by a prop proof of the lift caused by the low and high pressure created by the section. after all ,we dont measure the planes lift by the amount of air it throws down as it flys.
ollie?
