Abstract

Abstract A wind operated generator employing counterrotating propellers with an alternating current generator positioned between the blades of the propellors and spacing the same. The propellors and generator parts are mounted on concentric shafts supported in a positive drive structure in which the shafts are tied together through gearing to insure positive starting and counterrotation of the propellers in a positive equal drive system. A governor associated with one of the shafts governs the operational speed of rotation of both propellers to protect the propellors and generator.
