Question

Is shape of the airfoil depends on thickness?

(a) True

(b) False

The question was asked during an interview.

I want to ask this question from Airfoil Nomenclature in portion Incompressible Flow over Airfoils of Aerodynamics

Answer 1

Correct answer is (a) True

To elaborate: The shape of the airfoil depends on the thickness of the airfoil. The thickness of an airfoil varies along the chord. The thickness is measured perpendicular to the chord line. In NACA series the last two digits indicate the percentage of thickness.
