Question

Is supersonic flight uses supercritical airfoil?

(a) True

(b) False

The question was posed to me in unit test.

Asked question is from The Cambered Airfoil topic in division Incompressible Flow over Airfoils of Aerodynamics

Answer 1

Right choice is (a) True

To elaborate: To do different types of maneuvers at a speed Mach greater than 1. So, the designers use negative camber airfoil this is called super critical airfoil. It is used for near supersonic flight and produces high lift to drag ratio at near supersonic flight than a traditional airfoil.
