Awing with an elliptical planform is flying through sea-level air at a speed of 55 m/s. the wing is untwisted, has the same section from root to tip and its loading is w/s = 1000 n/m2 . the 2d lift curve slope is a0 = 5.7. the span of the wing is 15 m and the aspect ratio if 5. find, a) the sectional lift coefficient. b) the sectional induced-drag coefficient. c) the effective, induced and geometric angles of attack if l=0 = -2 degrees.
