Report KD 802 can be copied for free from my website at the menu KD-reports. The title of this report is: “Calculations executed for the 3-bladed rotor of the VIRYA-1.99 windmill (lambda design = 4.5, stainless steel blades) with the hinged side vane safety system using the generator of Hefei Top Grand type TGET260-0.5KW-350R for 24 V battery charging”. The advantage of this wind turbine is that no building permit is required in The Netherlands because the rotor diameter is smaller than 2 m.
