Chord length along distance y Calculator

The chord length ($c(y)$) of an airfoil section located at an arbitrary spanwise station $y$ is the straight-line distance between the leading edge and the trailing edge of the airfoil, measured perpendicular to the direction of the airflow. It is a fundamental geometric parameter that characterizes the shape and dimensions of the airfoil section at a specific spanwise location. 

• $c(y)$: Local chord length at the spanwise station $y$, measured in meters ($m$).
• L′(y): Lift per unit span at the spanwise station $y$, typically measured in newtons per meter ($N/m$).
• q∞​: Dynamic pressure of the free-stream air, measured in pascals (kg/m^3).
• cl​: Lift coefficient for the airfoil section at the spanwise station.
