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.(a) 118ft^2(b) 200ft^2(c) 1600in(d) 10mThis question was addressed to me by my school teacher while I was bunking the class.Question is from Configuration Layout topic in chapter Configuration Layout and Loft of Aircraft Design

Answer» CORRECT OPTION is (a) 118ft^2

To elaborate: 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 in^2 = 16981.44/144 ft^2 = 118ft^2.
