Question

2, (10 %) Please find the standard mean chord length and the mean aerodynamic chord length, where the standard mean chord length c is defined as b/2 -b/2 dy or, S = bc and the mean aerodynamic chord length-is defined as b/2 -b/2 b/2

Answer 1

Standard mean cuord length c^- c^- = integral_b/2^b/2 C dy/ integral _ -b/2 ^b/2 we know that integral_ -p^p dy = 2 integral_ - p^p dy therefore 2 integral_0^b/2 C dy/2 integral_0^b/.2 dy = c[y]_0^b/2/[y]_0^b/2 = c b/2/b/2 c^- = s/b mean aerodynamic clarod lenght C^_ C^- = integral^b/2_-b/2 C^2 dy/integral_-b/2^b/2 C dy C^- = bc^2/s
