(a) Flat wrap technique is cost effective

(b) Flat wrap is very costly

(c) Flat wrap is not lofting method

(d) Flat wrap is very much lift producing

This question was posed to me in an online quiz.

Origin of the question is Configuration Layout topic in division Configuration Layout and Loft of Aircraft Design

Answer 1

The correct choice is (a) Flat wrap technique is cost effective

The best I can explain: Flat wrap method is used for flat surfaces. Complex curvature are required more money to fabricate. If a surface is flat-wrapped then we can directly wrap a flat sheet around its cross section. By doing so we can reduce the cost and hence, it is cost effective.
