- Sweep angle
Hide Solution
Verified By Collegedunia
The Correct Option is D
Solution and Explanation
The sweep angle is the angle between the line of 25% chord of a wing and a line perpendicular to the root chord. This measurement is important for determining the aerodynamic characteristics of wings, particularly in high-speed aircraft to delay the onset of shock waves and reduce drag.
