Objetivo THE AIM OF THE PROJECT IS TO DEVELOP AN INTEGRAL (ONE PIECE) STALL REGULATED ROTOR WITH THE FOLLOWING IMPORTANT ADVANTAGES : - ELIMINATION OF THE COSTLY PITCH MECHANISM FOR TURBINES OF THAT SIZE. -ALL COMPOSITE ROTOR AVOIDING THE USUALLY DELICATE CONNECTION OF COMPOSITE MATERIALS TO A STEEL HUB. THE FOLLOWING TECHNICAL PROBLEMS RELATED TO THIS SPECIFIC APPROACH HAD TO BE SOLVED : - PREDICTION OF STALL BEHAVIOUR OF ROTORS OF THIS SIZE IS RATHER TRICKY. THEREFORE THE PROTOTYPE ROTOR WAS EQUIPPED WITH ADJUSTABLE TIPS SO THAT THE STALL LEVEL CAN BE EXPERIMENTALLY TUNED. FOR SERIAL PRODUCTION THE ADJUSTABLE TIPS WOULD BE REPLACED WITH CHEAPER FLYING EMERGENCY TIPS OR THE ROTOR CAN BE COMPLETELY FIXED (NO MOVING PARTS) DEPENDING ON THE STRATEGY FOR THE BACKUP SAFETY SYSTEM. - THE TRADITIONAL CONNECTION OF COMPOSITES TO STEEL HAD TO BE REPLACED BY SOME KIND OF TRANSITION METHOD SO THAT FORCES AND MOMENTS INTRODUCED BY THE ROTOR COULD BE TRANSFERRED TO THE CENTRAL HUB. FOR THIS SPECIFIC PROBLEM A "CLAMPING" HUB WAS DESIGNED THAT SURROUNDS THE CENTRAL PART OF THE ROTOR AND TRANSFERS THE PRESSURE BY MEANS OF RUBBER CUSHIONS BETWEEN ROTOR AND HUB. FURTHERMORE THOSE RUBBER BLOCKS HAVE THE ADVANTAGE OF ELIMINATING ROTOR INDUCED VIBRATIONS AND THEY ALSO PROVIDE A CERTAIN DEGREE OF FREEDOM FOR THE ROTOR IN THE HUB SO THAT LIMITED TEETHER MOTIONS CAN OCCUR.
