An aircraft with elliptic wing planform has parasite drag coefficient

1.	An aircraft with elliptic wing planform has parasite drag coefficient as 0.6. Lift coefficient of wing is 0.25 and aspect ratio is 7.5. If induced drag co-efficient is 0.0235 then, find total drag coefficient for the wing.(a) 0.06235(b) 0.5235(c) 0.6(d) 0.0235The question was posed to me by my school teacher while I was bunking the class.My question is taken from Wing Geometry-2 topic in section Airfoil and Geometry Selection of Aircraft Design
Answer» The CORRECT ANSWER is (a) 0.06235 The explanation is: Given, PARASITE DRAG co-efficient = 0.6, INDUCED drag coefficient = 0.0235 Total drag coefficient = Parasitic drag coefficient + induced drag coefficient = 0.6+0.0235 = 0.06235.
