ABSTRACT
This report describes the concept and final design phases of the EEC DGXVII contract. Under this contract and with the consponsorship of EEC/DGXVII and the Greek Public Power Corporation (PPC), the laboratory of Aerodynamics of the Nat. Techn. University of Athens and PPC undertook the design and construction of a 100 KW horizontal axis wind generator (HAWG); the machine is designed to operate on the island of Skyros at a site where wind measurements indicate a mean annual wind speed of 6.5 m/s. The features and characterestics of the wind generator as they evolved from a series of trade off studies include an upwind variable speed rotor of 20 m diameter with three fixed pitch blades, a planetary step-up gear box, a hydraulic low speed shaft disc brake, an electric high speed shaft disc brake and an 175 KW electric motor of 1500 RPM. Sismic analysis of the HAWG and its foundation indicated that an earthquaqe loading is of critical importance to the structural integrity of the system. The final design package of the machine consists of the components specifications, the anticorrosion measures due to sea proximity and of approximately 100 construction drawings; the Greek Aerospace Industry or BIEX probably will be the main subcontractor for the construction of the machine.
