Characteristic of blade

Pictures show the new generator wind blade and the wind blade's detail structure.

The impeller wing section design done carefully by the aerodynamics expert, according to the airscrew structure, takes shape by the intensity glass fiber reinforced plastic, the end joint tech has the extremely low starting and cut-in point, ensures the low wind start and stable quiet running.the wind power utilization ratio enhance up to 0.26 from the traditional 0.5, the extremely high wind power utilization ratio.

Our Hummer Dynamo limited company contrasts the domestic and foreign several small wind-driven generator match blade manufacturer's blade, through many tests in the foundation, the independent development has designed one kind of new wind blade.s

In view of the traditional glass fiber reinforced plastic wind blade cannot bear the gale, the low temperature easy break, the gale area service life not to surpass for 5 years and other flaws. Our hummer company developed high strength wind-driven generator wind blade which has controlled the type straight. This wind blade structure is firm, can bear 8 levels of gales.

Our hummer mini wind-driven generator adopts outside rotor unique design, reached "own energy consumption low, the wind power utilization ratio to be high?the high request. The new wind blade used cut -wind structure, the generator movement does not have the axial force, but can protect outside rotor maximum. Enabled the wind power utilization ratio enhance from traditional 0.26 to 0.43, has achieved the breeze start truly.s

Hummer wind blade's successful application causes the problem that gale area such as Inner Mongolian prairie and coast where the wind-driven generator's wind blade damage rate highly, is readily solved. Simultaneously made the entire wind turbine's service life prolong three to five years. Because hummer mini wind-driven generator wind blade use "the end joint tech? stable quiet running, also reduced the noise and has brought enormous convenient for user's use and replacement.s

The wind blade according to the airscrew structure and technics to manufacture, the wind blade has passed through the transient equilibrium test, firm and durable, design life for 8-10 years.s

After studying rotors blades at home and abroad, Hummer company independently designs a new type blade basing on a lot of tests

The traditional blades made in glass fiber reinforced plastic is not resistant to strong wind, it is easy to break at lower temperature and lasts less 3 years if used in strong wind areas. While Hummer's blade is solid and resistant to wind 8-grade up, which overcome the shortcomings of traditional products .
