KrisFlyZ 0 #1 April 29, 2007 Interesting reading... Induced Angle of Attack This is probably not applicable to wingsuits. How nature equiped birds to deal with induced drag The following link shows stream lines around an airfoil as the angle of attack is varied. Note the position of the stagnation point. http://www.diam.unige.it/~irro/profilo1_e.html Shows streaklines the stagnation point for an airfoil at 0, 15 and 30 degrees. Note where the stagnation point is at zero angle of attack. http://www.diam.unige.it/~irro/profilo1a_e.html [url "http://www.aerospaceweb.org/question/nature/q0237.shtml"> V Formation of birds and upwash effects Maybe we will figureout how to fly like birds and then no one will want to take Scott Bland's place in the formation.
