Particle-image velocimetry (PIV) is performed on the upper surface of a pitching airfoil in the NASA Glenn Icing Research Tunnel. PIV is a laser-based flow velocity measurement technique used widely in wind tunnels. These experiments were conducted as part of a research project focused on enhancing rotorcraft speed, efficiency and maneuverability by suppressing dynamic stall.

The 9x15 low speed tunnel tests take off and landing of aircraft. The laser velocimetry system for flow measurement show here, with the color blue and green lasers, measures engine exhaust that comes back up from the ground. The STOVL model n the 9x15 low speed wind tunnel, building 39, is similar to the British Harrier aircraft.
