CONSTRUCTION OF THE BLADES
• Challenging
• Very stiff and very light
• Only 130 gram
• 1.2m length of the blades
• Preferred thickness only 1-2cm
• Trailing edge thickness 1mm

SCALED MODEL WIND TURBINE
• Development of hardware
• Pitch control mechanism 40 deg/s
• Wind turbine blades (scaled weight) (0.2 kg)
• Total weight 5kg
• Less (stiff) cables for powering and instrumentation, and improve routing of the cable (e.g. underwater)
