Is a higher aspect ratio flat plates has a higher lift?(a) True(b) FalseI had been asked this question in an online quiz.This interesting question is from Downwash and Induced Drag in section Flow over Airfoils over Finite Wing of Aerodynamics

Answer»

Right choice is (a) True

To elaborate: The higher aspect ratio flat plates had higher lift and LOWER DRAG, a plane of fixed SIZE and WEIGHT would need LESS propulsive power the faster it flew, the counter-intuitive effect of induced drag will produce on the wing.
