Aerospace Engineering > GATE 2019 > Induced Drag
Consider an airplane with a weight of 8000 N, wing area of 16 m^2, wing zero-lift drag coefficient of 0.02, Oswald's efficiency factor of 0.8, and wing aspect ratio of 6, in steady level flight with wing lift coefficient of 0.375. Considering the same flight speed and ambient density, the ratio of the induced drag coefficient during steady level flight to that during a 30° climb is _______ (round off to 2 decimal places).
Correct : 1.32 to 1.35
