Consider below wing. Calculate the value of span of wing marked by ‘?’.(a) 3.3m(b) 6.66m(c) 3.36m(d) 6.96mThis question was addressed to me in examination.Origin of the question is Configuration Layout topic in chapter Configuration Layout and Loft of Aircraft Design

Answer»

Correct OPTION is (a) 3.3m

For EXPLANATION: Given, Cr = 4M, Ct = 2m, S = 20m^2

Taper ratio t = Ct/Cr = 2/4 = 0.5.

Hence, wing span of given wing b/2 = S/Cr*(1+t) = 20/4*(1+0.5) = 20/4*1.5 = 3.3m.
