Trailing edge term.

Trailing edge term.

• A. Leading edge
• B. Trailing edge
• C. Camber line
• D. Mean line

Answer: (B)

The trailing edge is the rear boundary of an airfoil—the edge where the upper and lower surfaces meet at the back, opposite the front leading edge. It defines where the flow leaves the airfoil, affecting drag and the overall aerodynamic behavior of the blade. The camber line is the curve that traces the airfoil’s mean curvature between surfaces, while the mean line is a reference line roughly halfway between the upper and lower surfaces used to describe thickness. So the term for the rear edge is the trailing edge.
