Question: A straight wing is elliptic and untwisted, and is installed symmetrically in a wind tunnel with its centerline along the tunnel axis. If the air in the wind tunnel has an axial velocity V and also a small uniform angular velocity ω about its axis, show that the distribution of circulation along the wing is given by
Γ = 2sA2 sin 2Θ
and determine A2 in terms of ω and the wing parameters. (The wind-tunnel wall corrections should be ignored.)
