An Engineer Designed A New Wing Body And Was Tested In A Wind Tunnel The Experimental Data Measured From The Wind Tunne 1 (65.9 KiB) Viewed 40 times

An engineer designed a new wing body and was tested in a wind tunnel. The experimental data measured from the wind tunnel are the following:< Lift = 0 at Angle of Attack a = -1.5⁰. Coefficient of lift = 0.52 at Angle of Attack a = 5⁰ CM,cgwb = -0.01 at a = 1⁰ CM,cgwo = 0.05 at a = = 7.88⁰ C. G. at 0.35c (1) Find the lift curve slope (awb) of the wing. (ii) Find the static margin of the wing. (iii) Find the location of the aerodynamic center and the value of CM,acwb 2 Where, CM,acwb Pitching moment coefficient about aerodynamic center awb: Lift curve slope of wing awb: Angle attack of wing hacwb: Distance between wing leading edge and aerodynamic center Given that: CM,cgwb = CM,₁acwb + awbawb (h-hacwb)<
