Laser Displacement Sensors for Wind Tunnel Model Position Measurements [PDF]
Sensors, 2018 Wind tunnel measurements of two-dimensional wing sections, or airfoils, are the building block of aerodynamic predictions for many aerodynamic applications. In these experiments, the forces and pitching moment on the airfoil are measured as a function of the orientation of the airfoil relative to the incoming airflow.
