Adaptive gurney flap for rotor blades

open access: yes, 2013
Desde muito tempo vários esforços tem sido feitos de maneira a optimizar o rotor dos helicópteros com o objectivo de reduzir a emissão de poluentes. Durante vários anos foram feitas várias optimizações estrutrais na pá do rotor. Estudos recentes numéricos e experimentais mostram que para melhor a performance do rotor várias considerações aerodinâmicas ...

Proportional Control of Aerodynamic Forces Using an Active Gurney Flap on a Wind Turbine Blade Section

open access: yesWind Energy
Real‐time, proportional deployment of an active Gurney flap (AGF) located near the trailing edge of the wind turbine blade on the pressure surface is used to modulate aerodynamic performance. Wind tunnel experiments are conducted using an AGF model based
