Problem 5.4 Answer again the question of Problem 5.3, but now for the case where the wing is represented by a combination of two horse-shoe vortex systems, which are located in the same plane (viz. z=0). For both horse-shoe vortices the section that corresponds to the bound vortex is evidently located at the quarter-chord line of the wing (x=z=0). Let the first horse-shoe vortex extend over the entire wing span (free vortices at y=-b/2 and +b/2) and the second one over half the wing span (free vortices at y=-b/4 and +b/4). Assume that both horse-shoe vortices have the same, constant circulation strength . N.B.: Start by making a good sketch of the vortex geometry!
