Baughman, H E

A rotary machine to be driven by a flow stream, such as wind or a water stream, includes a housing with a semi-cylindrical back wall and horizontal top and bottom walls. A plurality of intake ducts open across the front of the housing to direct flow against a plurality of vertical vanes carried on and around a cylindrical rotor within the housing. The ducts on one side of the front-to-back centerline project air streams directly in, in the direction of rotation, while those on the other side of the centerline reverse the stream so that they will also impinge upon the vanes in the same rotational direction. The vanes are configurated as airfoils so that, in addition to the reaction to the flow impingement, there will be a lift vector in the direction of rotation. In one embodiment, the airfoil vanes are disposed in rows of two or more from outside to inside, closely spaced to form venturi slots between them.
