Abstract

The windmill consists of a main support with guy lines. The support is connected to a central star wheel which has six radial arms. Each arm carries smaller star wheels also with six arms. Each arm carries a three bladed propeller, which directly drives a generator. The propellers may have a feathering mechanism and the generator may alternatively be geared to the propeller to allow several generators to be mounted on one shaft.
