For a finite wing, induced drag increases with an increase in aspect ratio.(a) False(b) TrueThe question was posed to me in class test.I need to ask this question from Prandtl’s Classical Lifting-Line Theory topic in division Flow over Airfoils over Finite Wing of Aerodynamics

Answer»

The correct choice is (a) False

Best explanation: The INDUCED drag coefficient for a finite wing is inversely dependent on the ASPECT ratio. Thus, the induced drag INCREASES with the decrease in aspect ratio and VICE versa for a finite wing with the same LIFT.
