When discussing aircraft and their ability of flight, you may see the term airfoil being used just as much as wings when describing the lift generating surfaces that make powered flight possible. While the two terms are not quite interchangeable, they are very much connected. In general, an airfoil is simply a specific shape that allows for lift generation, thus being the standard shape that wings are constructed in. Alongside this, fans, propellers, stabilizers, and other various surfaces may also utilize the airfoil shape, proving its usefulness for the manipulation of airflow and aerodynamics. To help you better understand how flight is made possible, we will provide a brief overview of airfoils and their various characteristics.
