Is it difficult to predict the amount of lift that a wing geometry will generate?(a) False(b) TrueI had been asked this question in an online quiz.My question is from Prandtl’s Classical Lifting-Line Theory topic in portion Flow over Airfoils over Finite Wing of Aerodynamics

Answer»

Correct answer is (b) True

Explanation: It is difficult to PREDICT analytically the overall amount of lift that a wing of GIVEN geometry will generate. The lifting line theory yields the lift distribution along the span-wise DIRECTION, based only on the wing geometry and flow conditions.
