Automating Wing Angle Changes inside the LARCASE Price – Païdoussis Wind Tunnel

Student researchers at ETS designed an aerodynamic balance to automatically rotate parts of their reduced scale models at precise angles inside a wind tunnel in order to calculate lift, drag and moment coefficients. This aerodynamic balance was installed in the subsonic Price-Paidoussis wind tunnel of the Montreal Aeronautical Research Laboratory in Active Control, Avionics and Aeroservoelasticity (LARCASE), at the Ecole de technologie superieure (ETS). The balance significantly reduces the duration of wind-tunnel testing of model reduced scale rotating parts.
