Experimental Analysis of Bio-Inspired Vortex Generators on a Blade with S822 Airfoil

Vortex generators are used in aircraft wings and wind turbine blades. These devices allow them to maintain a stable turbulent behavior the wake. generators, or VGs, improve transition from laminar boundary layer regime, avoiding abrupt shedding. HAWT turbines have high rotational velocity. Currently, being redesigned with fixed vortex achieving higher energy production. This paper presents tunnel analysis of fixed-wire blade S822 airfoil active VGs bio-inspired by flight-stabilizing feathers peregrine falcon. Vibrations measured on show reduction intensity at velocities close 15 m/s. The wake fluctuations velocities. An FFT spectral showed differences between components. When activating oscillation constant frequency, vibrations was observed for around 20
