Chord Line Definition
The chord line refers to an imaginary straight line that runs through an airfoil from its leading edge to its trailing edge. It is an essential reference line in the study of aerodynamics, used to calculate the lift and drag forces acting on the airfoil.
The chord line serves as a baseline for measuring the airfoil’s dimensions, such as the chord length and the camber. It is the line that separates the upper and lower surfaces of the airfoil, and its length is equal to the distance between the leading and trailing edges.
The position and orientation of the chord line can vary depending on the design of the airfoil. For example, some airfoils may have a curved chord line to provide better lift-to-drag ratio, while others may have a straight chord line for simplicity.
In summary, the chord line is a crucial concept in aerodynamics, providing a standard reference line for the measurement and analysis of airfoils.
