Aeolon - Model AL91A2 -Wind Turbine Blade
The AL91A2 wind turbine blade, developed by Aeolon, represents a sophisticated engineering feat in wind energy technology. With a blade length of 91 meters and designed under IEC S standards, it exhibits a maximum chord length of 4.8 meters and a pre-bending of 6.5 meters. The blade's mass totals 23.7 tons excluding T-bolts, which add an additional 615 kilograms. The center of mass is positioned at a radius of 25.876 meters. Structured to last for 20 years, the blade is constructed from E/H-glass reinforced epoxy. Operationally, it is equipped for a rated power of 5.x MW, a rotor diameter of 185 meters with three blades, and is capable of pitchable and variable-speed power control. The speed range is between 5-10 rpm, with a rated tip speed of 87.13 m/s and rated rotor speed of 9 rpm, achieving an optimal tip speed ratio of 11.2 and a performance coefficient at optimal TSR of 0.477. The blade connection is secured through an insert principle with a bolt hole circle diameter of 3200mm and uses 128 tension bolts of size M36X4.0 10.9, with the outer root diameter measuring 3310mm.Most popular related searches
