Unformatted text preview: m = -π h Hint: Use an approach identical to the worked-out example 4.2 in the text. 3. Consider a symmetric airfoil, with a flap hinged at x= x f . This flap is deflected by an angle δ so that the camber line looks like the sketch below. Show that the lift generated by the flap deflection is given by: ( 29 [ ] ( 29 ( 29 σ δ π cos 1 2 1 : such that defined is where 1 cos sin 2 1 2 2 4 / ,-=-= +-= f c m l x C in C Hint: Use an approach similar to problem #2 above....
