Based on aviation technology (helicopter propeller) advantages and international standards to develop
wind turbine blade;

Structure damping technique (HT’s patent) can decrease blade vibration in low temperature;

HT tip proprietary technique can increase blade aerodynamic performance and decrease operation noise;

“Mirror-surface” mould technique can increase blade surface fineness and then improve blade aerodynamic
performance;

Vacuum infusion process can improve product quality;

Used material adopts aviation structure adhesive formula has good low-temperature-resistance;

High precision balancing technique can reduce weight difference in one set blades, furthermore improve
wind turbine startup and operation performance;

High precision location technique at blade root can increase blade mounting efficiency.
