Now what has the SOURCE of the air pressure got to do with the discussion? A great deal. Without gravity, air pressure would be zero, and volume would be infinite. As a student pilot, if you have no gravity, you could have smaller wings on your airplane, right? Well, no. The gas 'laws' are approximations and fail to be predictive except within certain ranges, just as Newtonian physics are valid only in certain ranges.. Doing wing sectional sims, I used the centrifugal force of the displaced air over the wing surfaces. It is a fairly simple algorithm, in accord with physics, and works surprisingly well. It also stalls well, since Energy=Force x distance, and once the airstream kinetic energy is bled off, the airstream reverses and follows the wing to give turbulence. Good Stuff. Ken |
