Report KD 805 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-3.5B3 windmill (lambda design = 6, wooden blades, Gö 711 airfoil) with the hinged side vane safety system using the generator of Hefei Top Grand model TGET320-1KW-350R for 24 V battery charging”. KD 805 replaces KD 705 about the VIRYA-3B3 using the same generator.

At 16-6-2026 a new chapter 7 has been added to KD 805. The title of this chapter is: “Drawings of the VIRYA-3.5B3”. The drawings of the 2-bladed VIRYA-3.5 have been modified such that now there is a detailed drawing of all components of the VIRYA-3.5B3.
