100-KW HINGELESS METAL WIND TURBINE BLADE DESIGN ANALYSIS AND FABRICATION

摘要

The design, fabrication and analysis of aluminum wind turbine rotor Hades is discussed. The blades are designed to meet criteria established for a 100 kilowatt wind turbine generator operating between 8 and 60-milc-per-hour speeds a:40 revolu¬tions per minute. The design wind speed is 18 miles per hour. Two rotor blades are used on a new facility which includes a hingeless hub and its shaft, gearbox, generator and tower. Experi¬ence shows that, for stopped rotors, safe wind speeds are strongly dependent on blade tensional and bending rigidities which the basic D spar structural blade design provides.
