If for a given fuselage Stop=10m^2, Aside=14m^2, L = 10m then, find the ratio of wetted area to the volume of fuselage.(a) 3.42 per m(b) 6.68 per m^3(c) 8.36 m(d) 4.001I have been asked this question by my college director while I was bunking the class.This intriguing question originated from Configuration Layout topic in portion Configuration Layout and Loft of Aircraft Design

Answer»

Correct answer is (a) 3.42 per m

The EXPLANATION: GIVEN, Stop=10m^2, Aside=14m^2, L = 10m.

Now ratio of wetted area AW and volume V is given by,

Aw/V = 2*L*(Stop + Aside) / (Stop*Aside)

Aw/V = 2*10*(10+14) / (10*14) = 20*24/140 = 3.42 per m.
