Hello everyone This is my first post. I am currently making a simulation of a P-51 Mustang in Blender3d. ("www.blender.org"[/URL]) as the other ones are from the Wright section of the NASA website as well. If someone could explain these in simple terms for me (as I am only a tenth Grader) (or jsut tell me how to get the Static pressure, as thats the main problem) it would be appreciated. The Lift and Drag calculations are from [PLAIN]http://wright.nasa.gov/airplane/lifteq.html" [Broken].
