On the Use of Cambered Plate Airfoils for Small Wind Turbines

The use of constant thickness, cambered plates is being explored as a means to reduce the cost of rotors for small wind turbines. Literature suggests that at low Reynolds numbers there is an advantage over conventional airfoils, and tests conducted on a 2.5 m ducted rotor indicate a constant thickne...

Description
Summary:The use of constant thickness, cambered plates is being explored as a means to reduce the cost of rotors for small wind turbines. Literature suggests that at low Reynolds numbers there is an advantage over conventional airfoils, and tests conducted on a 2.5 m ducted rotor indicate a constant thickness airfoil to be a viable solution. An operational turbine with a 3 m rotor was developed and is currently being tested. Data supports predictions and shows encouraging results.
