For a cambered airfoil, the center of pressure does not vary with_____(a) Chord length(b) Angle of attack(c) The shape of the airfoil(d) Location of the aerodynamic centerThe question was asked in an interview.I'd like to ask this question from The Cambered Airfoil topic in division Incompressible Flow over Airfoils of Aerodynamics

Answer»

Correct option is (d) LOCATION of the AERODYNAMIC center

To elaborate: This solution is best ANSWERED from the FORMULA for the center of pressure which is xcp=\(\frac {C }{4}\)(1+\(\frac {\pi }{c_l}\)(A1-A2)). Moreover, the aerodynamic center is located at the quarter-chord but the center of pressure keeps changing with the other three parameters.
