Thread: Velocity Loss From Summer to Winter.

Jeez guys we are getting into principles of flight here as far as aerofoil designs and lift. I havnt studied any of that stuff for over a decade. In saying that you are right to the best of my knowledge Sneeze.
The idea is to create high pressure under the aerofoil and low pressure at the top. Therefore creating lift. Most rotor blades are symetrical however and change the angle of attack by applying pitch.
As far as a projectiles resistence thru "air" I am not sure on the measured effects, but do see a difference from a low pressure day to a high pressure day in my calcs for said range. It can be a bit and enough to miss at range if not taken into consideration.
