Quasi-Steady Analysis of a Small Wind Rotor with Swept Blades

It is well known that wind power generation addresses the energy needs of small and remote populations as one alternatives to petroleum-based energy’s greenhouse effect. Although there are several publications on rotor design performance analysis, more should be written about starting turbines, mainly ones, where can a big issue. The present paper evaluates impact swept blade angle aerodynamic torque, thrust force, minimal speed required start operation compact horizontal-axis turbine. presents novel investigation influence blades turbine drivetrain. methodology uses element moment theory coupled Newton’s second law, in which Palmgren’s extended approach employed. When proposed compared experimental data available literature, it exhibits good agreement. However, when starts run, results show do not always enhance torque coefficient or reduce force indicated some scientific papers. For backward-swept blades, maximum value decreases 4.0%. Similar behavior found for forward-swept blades. Therefore, study evaluate many foils operational environments confirm this statement.
