Think of it like this if you blow on a thin peice of paper from the bottom it would go up but if you were to blow on it from the top then it would go down. So when the blades on a helicopter rotate it creates air resistance below it there fore making it easy for it to fly.

In terms of impulse and momentum why is it important that helicopter blades deflect air downward?
