The higher the lift-to-drag ratio, the more efficient the turbine blade is at converting wind energy into torque, which produces more electricity from the generator. Turbine blades have the highest lift-to-drag …

Factors that Affect Drag

Windmill construction and its working principles

2019-11-17 · • The force of the lift is stronger than the drag and this causes the rotor to spin. • The rotor is connected to the generator, either directly (if it''s a direct drive turbine) or through a shaft and a series of gears (a gearbox) that speed up the rotation and allow for a physically smaller generator.

Effect of Drag on the Performance for an Efficient Wind ...

2012-1-1 · The lift/drag ratio ( shown in Fig. (4)) has a significant affect upon the efficiency of a wind turbine and it is desirable that a turbine blade operates at the maximum ratio. The nature of the flow pattern around an aerofoil is determined by the Reynolds number and this significantly affects the values of the lift and drag coefficient.

Aerodynamics of Wind Turbines: Drag

2014-10-6 · Both lift and drag increase with the square of the wind speed. The reason why drag is much more of a problem for a racing bicyclist than for, say, a runner, is that a fast runner will be moving at speed of some 6 m/s (21 km/h, 13 mph), whereas a racing bicyclist is moving at a speed of some 12 m/s (42 km/h, 26 mph).

Analysis of Aerodynamic Forces Acting on the Blade

The drag force, F D is parallel to V R. The vector sum of F L and F D is F R which has a torque producing component, F T and a thrust producing component. The former is what drives the aero-turbine rotationally and the later tends to flex and also overturn the aerogenerator. The vector diagram is centred on the centre of lift …
