A prototype design and performance of the Savonius rotor based irrigation system Roth, Neal Joseph


Important stages in the development of a wind energy operated irrigation system, which is simple in design and easy to maintain, are described from model tests in wind tunnels through to a prototype prepared for field tests. The attention is focussed on gross features of the protoype including the blade geometry and aspect ratio; mast, sleeve and bearing assemblies; braking system and a load matching concept. Described towards the end are the field test arrangements of the prototype and associated instrumentation. Even according to the most conservative estimate, the prototype tests suggest that the windmill should be able to deliver around 3000 liters of water per day (eight hours of wind) to a head of 5 m in a 24 km/h wind.
