Hurricane Stealth Storm Wind Turbine Blades (set of 5 blades) total blade length 40 Inches
Building a DIY turbine and thinking of using water pipe? Not so fast we have got the parts for you. Safe time and do DIY the safe way
Our blades have great surface area and a lot of great features great for low wind startup and eliminates the need for furling. Great for turbine with output generators 800-1200 watts. Using smaller blades will result in less output as the diameter of the blade determines kinetic energy or torque input to the generator or permanent magnet alternator
Could be used as replacement for Hy Energy, Aleko Skymax and of course as used on Vector and XP Turbines. If buying as a replacement blade contact seller prior to purchase to check for blade weight and or compatibility
Hurricane Wind Power is making our wind turbine blades available that we use on our XP and Vector wind Turbines. We have had good luck with these blade which feature one major advantage over our competitors!
It called Dynamic blade braking:
Hurricane Stealth Storm Wind Turbine Blades utilize their airfoil as a method of breaking eliminating the need for furling and the associated wear that comes with the turbine being violently moved about in high winds which contribute both to bearing wear, blade tension and many other undesirable forces acting on small wind turbines in high speed wind operation.
Hurricane Stealth Storm Wind Turbine Blades utilize asymmetrical and twisted aerodynamic design which ensures rotor capture maximum power from wind (Cp>0.32 in low wind) and operates in amazingly low noise and minimal vibration.
Large ratio of tip section chord to root section chord and variable chord airfoil blade ensures rotor start-up easily and running smoothly with high torque & RPM at low wind conditions Aerodynamic blades designed with over-speed dynamic blade braking systems ensure the generator is well protected in higher winds.
Reinforced nylon glass-fiber using advanced thermoplastic engineering and precision injection molding technology for higher strength, flexibility and reliability .Cp.>0.32 at low wind
Typical wind turbines have three moving parts The generator head, yawing and mechanical furling body parts, Hurricane replaced mechanical furling by using advanced electromagnetic and Dynamic blade braking which only take two moving parts, this in turn improves generator reliability significantly as it is subject to less mechanical failure and bearing wear from stress and impact.
Smart Stealth Blade Aerodynamics Braking and Electromagnetic Speed Limitation
Abandoned the traditional failure-prone mechanical furling system, the blade itself is designed with over-speed braking system which will generate a reverse reluctant torque to lower the blade rotation speed so that the blades and generator can be well protected in higher wind, it solved safety and reliability problems facing by most small wind turbines. Combination of Electromagnetic braking and aerodynamic braking maximizes energy capture by extending turbine’s operating speed range into higher and lower wind speed which are missed by the old style wind turbines
As with all things that have with moving parts there will be some noise and vibration, and wind turbines are no exception, most noise and vibration are caused by turbine blades rotation in the wind and generator resonating with the rotor and tower, and generator bearings Hurricane stealth blades are well designed and work quietly in both low and high wind.
The blades have exceptional consistency and aerodynamic outline with a mass distribution which ensures the rotor/ blade set operates with minimal vibration and very low noise. Perfectly matched to the Hurricane White Lightening XP and Vector wind generators the blade cause much less resonance of the wind turbine and tower.
Blade Aerodynamics Braking limits blade to rotate at the rated RPM which could avoid higher noise and vibration caused by extreme wind. Wind turbine with minimal vibration and low noise can be mounted on rooftop safely and its operation won’t affect the resident.
