<p>1. An airfoil for air-plains with short take-off and landing capability, and cruis speeds up to about 700 km/h having a center line (S) which includes a first forward point (b1 ) at about x/l = 0,15 with a first camber maximum of about 1,54% of the length (I), a rear point (b2 ) at about x/l = 0,7 with a second camber maximum which is about 1,94% of the length (I), a point (b3 ) located between the forward and the rear point (b1 and b2 ) and at about x/l = 0,4 representing a camber minimum of about 1,4% of the length (I), and where a profil droplet is superposed an the center line (S) and even thickness distribution (D), having a forwad point of about YD /l = 0,059 at about x/l = 0,42 by a point YD /l = 0,08, a point at about x/l = 0,7 of about YD /l = 0,052 and by a rear point of about YD /l = 0,003 5 and said profile also having a nose radius (r) of about r/l = 0,014 5.</p> |
