Report KD 617 from November 2016 has been added to the menu “KD-reports”. 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 2 mm 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.
