Question 3: Consider a trapezoidal wing with no geometrical twist flying at 30ft/s and a span of 50 ft and a wing area of 312.5ft^2. The airfoil section has ao=-1. The geometric angle of attack is 3". Assume the circulation distribution along the wing can be approximated by a sine series N Γ(0) = 2bVΣ A„ sin no 1 with A1-0.014247, A2-0, A3-0.000851, A4-0, A5-0.000615, A6-0 and A7=-0.000024. a. Write out the equation of the circulation I as a function of Ⓒ (y=-b/2 cose) b. Find the equation of the 3D lift coefficient C. Calculate the 3D lift curve slope d. Calculate the span efficiency factor Calcukate the induced drag coefficient e.
