Chord Line


In aviation, chord line refers to an imaginary straight line that runs from the leading edge to the trailing edge of an airfoil. It is the line that connects the two endpoints of the airfoil's curved surface. The length of the chord line is used to determine the size and performance of an airfoil. The chord line is also used to calculate the angle of attack, which is the angle between the chord line and the relative wind. This angle is important because it affects the lift and drag of the airfoil. The chord line is a fundamental concept in aerodynamics and is used extensively in the design and analysis of aircraft.
