Let’s consider flat wrapping is to be used for lofting. If wing has taper ratio of 0.4, span of 26.6ft and root chord Cr is 76in then, find the area to be covered by flat wrapping.

Let’s consider flat wrapping is to be used for lofting. If wing has taper ratio of 0.4, span of 26.6ft and root chord Cr is 76in then, find the area to be covered by flat wrapping. Correct Answer 118ft2

Given, Cr = 76in = 76*12ft = 912ft, span b=26.6ft, taper ratio t=0.4 Area S is given by, S = Cr*b*(1+t)/2 = 912*26.6*(1+0.4)/2 = 16981.44 in2 = 16981.44/144 ft2 = 118ft2.
