AE 2020 Homework #5 Due 4/12/11 1. Using the Biot-Savart law, calculate the velocity at the center of a vortex square with sides of length h, and a strength of Γ. 2. A plane is flying at an altitude of 1000 m. The wing has a straight leading edge, a span of 10 m, a root chord length of 2 m and a tip chord length of 1 m with straight taper. The loaded weight of the plane in level flight is 24513 N. The
