Following diagram represents _______________(a) cambered wing lift curve(b) drag polar(c) thrust loading(d) power loadingI had been asked this question during an interview for a job.This interesting question is from Aerodynamics in division Aerodynamics of Aircraft Design

Answer»

Correct answer is (a) cambered wing lift curve

Explanation: A typical, lift curve is shown for Cambered airfoil. As shown in the diagram, camber wing with cambered airfoils will produce lift at SMALL angle. Drag POLAR is used to provide INFORMATION about drag characteristics. THRUST LOADING is defined as ratio of weight to thrust.
