KD 634 added, KD 490 reviewed

Report KD 634 has been added to the list of free public KD-reports. The title of this report is: Calculations executed for the 3-bladed rotor of the VIRYA-3.4 windmill (lambda design = 4.5, galvanised steel blades) driving a centrifugal pump through a Polycord transmission with i = 2.5 and a vertical shaft in the tower centre. Report KD 623 has been added to the references of report KD 490: Water pumping with a windmill.

Polycord data sheet added to KD 320

The original pdf file of report KD 320 about the Polycord transmission of the VIRYA-2.8B4 was larger than 2 Mb and therefore it could not be added to my website completely. The data sheet of the Polycord transmission in between the rotor shaft and the vertical shaft was therefore removed. This data sheet has be scanned again but now on a lower resolution of 100 dpi and the report is now small enough to present it completely.
