What is the front part of an airfoil called?

The front part of an airfoil is referred to as the leading edge. This term is essential in understanding airfoil design and aerodynamics, as it is the section that first encounters oncoming airflow. The shape and design of the leading edge play a significant role in determining how air flows over the airfoil, influencing lift and drag characteristics. A properly designed leading edge can enhance performance by reducing turbulence and improving overall aerodynamic efficiency.

In contrast, the trailing edge is found at the back of the airfoil and is where the airflow reattaches after flowing over the surface. Thickness refers to the overall measurement of the airfoil from the top to the bottom, which can also affect aerodynamic properties but is not specifically the front part. Camber describes the curve of the airfoil's upper and lower surfaces, which influences lift but does not pertain to the leading edge itself.
