The front edge of the airfoil is a crucial aspect of its design and performance. This edge, known as the leading edge, is the part of the airfoil that first encounters the airflow as the aircraft moves through the air. The aerodynamic characteristics of the leading edge play a significant role in generating lift.

When air flows over the airfoil, the shape and design of the leading edge influence how the air separates and attaches to the surface, which impacts the overall aerodynamic efficiency and performance of the rotor blade. Effective design of the leading edge can help in minimizing drag and maximizing lift, which are vital for the optimal functioning of a helicopter.

Distinguishing this from other elements, the back edge refers to the trailing edge where air exits the airfoil. The center of gravity is a different parameter that involves the distribution of the aircraft's weight and balance, and the curvature of the airfoil relates to its camber, which affects lift but is not limited to the leading edge. Understanding these components is essential for a thorough grasp of helicopter aerodynamics.
