Correct Answer : Lofting done by using various conic curves
Explanation : When lofting is done by using conic curves then, it is termed as conic lofting. Conic lofting may include only circles but it is not mandatory that if conic lofting is mentioned then, it will have circles only.
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.
