Question

Modern low-speed airfoils were developed using numerical methods using the computer directly. The given statement is_____

(a) Partially true

(b) False

(c) True

(d) Incomplete

The question was posed to me during an interview.

The doubt is from Modern Low Speed Airfoils topic in chapter Incompressible Flow over Airfoils of Aerodynamics

Answer 1

Right option is (a) Partially true

The best I can explain: The modern low-speed airfoils were developed using numerical techniques on the computer which was followed by wind- tunnel testing to confirm the computer results. This gave the definite airfoil properties for the new airfoils.
