Report KD 617 from 2016 can be copied for free from my website:
www.kdwindturbines.nl. The tittle of this report is: "Design report of the VIRYA-2.02 rotor (lambda design = 6, B = 2, tapered stainless steel blades)". The geometry of the VIRYA-2.02 rotor was already given in chapter 5 of report KD 616 but the design calculations are given in KD 617.
The 2-bladed VIRYA-2.02 has blades which are made from a stainless steel sheet size 2 * 250 * 833 mm. This sheet is cambered first and then ground into two tapered blades. The two blades are connected to each other by a stainless steel connecting strip size 3 * 166 * 416 mm which is cambered at the ends and twisted. To give an impressing of this rotor, figure 1 out of KD 617 is added as an attachment.
