Question

Is NACA 0012 is symmetric airfoil?

(a) True

(b) False

The question was asked by my school principal while I was bunking the class.

My question is taken from The Symmetric Airfoil topic in section Incompressible Flow over Airfoils of Aerodynamics

Answer 1

The correct answer is (a) True

For explanation: The NACA 0012 is symmetric airfoil because the mean camber line and chord line intersect in the same line.so, there is no camber in the NACA 0012 airfoil. That the reason the first and second digits are will become zero, and the thickness of NACA 0012 airfoil is 12 percent.
