Correct Answer : overall aerodynamic concepts, location of components etc
Explanation : A good sketch is the one that highlights as much as detail as it can. It should include overall aerodynamic concepts, internal placements of components, landing gear location etc.
Correct Answer : Option (A) : 3.42 per m
Explaination : Given, Stop=10m2, Aside=14m2, 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.
Correct Answer : Option (A) : 4m²
Explaination : Given, planform area = 2m².Since, wing is paper thin wetted are = 2*planform area = 2*2 = 4m².
Correct Answer : Option (B) : 16.16m²
Explaination : Given, Aw = 64.64m².Now, average projected area A = Aw/4 = 64.64/4 = 16.16m².
