Is prandtl lifting line theory predicts lift distribution over a three dimensional wing?(a) True(b) FalseI had been asked this question during an online exam.The query is from Prandtl’s Classical Lifting-Line Theory topic in division Flow over Airfoils over Finite Wing of Aerodynamics

Answer»

Correct choice is (a) True

Easy EXPLANATION: The prandtl lifting-line theory is a mathematical MODEL that predicts lift distribution over a three dimensional wing based on its geometry. It is ALSO known as the lanchester-prandtl wing theory. The theory was expressed independently by Frederick W. lanchester in 1907.
