Question

Is NASA designed low speed airfoils?

(a) True

(b) False

I have been asked this question in unit test.

This interesting question is from Modern Low Speed Airfoils in portion Incompressible Flow over Airfoils of Aerodynamics

Answer 1

Right answer is (a) True

The explanation is: During 1970s, NASA designed a series of low-speed airfoils that have performance superior to the earlier NACA airfoils. The standard NACA airfoils were based almost exclusively on experimental data obtained during 1930s and 1940s.
