Notice. New forum software under development. It's going to miss a few functions and look a bit ugly for a while, but I'm working on it full time now as the old forum was too unstable. Couple days, all good. If you notice any issues, please contact me.
Hereby I want to draw your attention to my latest public report KD 791 which can be copied for free from my website: www.kdwindturbines.nl at the menu KD reports. The title of this report is: "Calculations executed for the 3-bladed rotor of the VIRYA-5B3S windmill (lambda design = 6.5, stainless steel blades) meant for connection to the axial flux generator of Hefei Top Grand type TGET450-5KW-300R for grid connection or water pumping".
