The Rutland 910-3 Furling wind turbine is based upon the 913 design but with an added 'furling' device.
This tilts the turbine horizontally at wind speeds exceeding 35 mph, making it most suitable for land applications. This protects from the damage and stress subjected on the turbine and tower during high wind speeds. Therefore this turbine is most suited to unmanned power generation in environments where extreme conditions and high speed winds are common. Examples of prior Rutland projects include applications in Antarctica and the Himalayas.
Wind turbines
Swept area
The Rutland FM 910-3 has a blade diameter of 0.91 metres. This means it has a swept area, or capture area of 0.65 square metres. The swept area is all important when comparing wind turbines, since it directly relates to the amount of passing wind energy the turbine blades can intercept.
Rutland FM 910-3 power output curve
The graph below shows the power produced (in watts) for the Rutland FM 910-3 at different wind speeds, based on data supplied by the manufacturer.
Whilst the above graph gives an indication of the instantaneous power you might expect from the
Rutland FM 910-3 turbine, working out annual power production is more complex.
The only way to know for sure is by measuring your wind speeds using an anemometer for a period of time and then working out what a generator like this would produce.
Luckily, we've invented something that makes this easy, called the
Power Predictor!
Power output
This turbine produces roughly 24 Watts power at wind speeds of 5m/s and can produce up to 300 Watts of power at high wind speeds.
Cost
The cost of this turbine alone is £510 including VAT, however an extra £100 - £140 must be allowed if a a tower and mounting kit is required.
