The Correct Option is A
Solution and Explanation
Step 1: Define Supercritical Airfoil.
A supercritical airfoil is designed to delay the onset of shock waves and reduce the effects of wave drag at high subsonic speeds, near transonic conditions.
Step 2: Purpose of Supercritical Airfoil.
The purpose of a supercritical airfoil is to increase the drag divergence Mach number. This means the airfoil allows the aircraft to fly at higher subsonic speeds without a significant increase in drag due to shock waves.
