发明名称 Windmill
摘要 This invention involves a windmill apparatus and method of operation therefor. The windmill has a mirror-image pair of blade assemblies mounted for rotation about a common horizontal axis. Each blade assembly has a vortex creating or directing means positioned substantially thereabout which serves to channel the incoming wind about the horizontal axis to create a vortex of whirling winds. The creation of the vortex intensifies the driving force of the incoming wind to increase the rotational velocity of each blade assembly and the efficiency of the windmill. A common aligning means for the pair of blade assemblies serves to continuously align the windmill into the incoming wind with the horizontal, rotational axis of each blade assembly substantially perpendicular to the direction of the incoming wind. A back portion of each directing means has an upper section that captures a part of the incoming wind above the closed path of rotation of each blade assembly and deflects it downwardly to strike the blade members in each assembly at a substantially right angle to create a high torque force thereon. The invention also includes a governor arrangement responsive to increases in the force of the incoming wind above a predetermined amount. The method of the present invention includes the steps of mounting a plurality of blade members for rotation about an axis and directing the incoming wind about that axis to create a vortex of whirling winds to drive the blade members of each assembly.
