A journaled rotor is provided for rotation about an axis to be disposed transverse to a fluid flow path and the rotor includes a plurality of mounting portions spaced radially outwardly from and circumferentially about the axis having a plurality of vane assemblies rotatably mounted therefrom for angular displacement about axis generally paralleling the axis of rotation of the rotor. Vane assembly displacement control structure is operatively connected to the vane assemblies for angularly displacing the vane assemblies relative to the corresponding mounting portions 180 degrees each 360 degrees of angular displacement of the rotor and in directions opposite the direction of angular displacement of the rotor upon rotation of the latter. The vane assemblies are variously optimumly angularly positioned relative to the corresponding mounting portions and each other to effect substantially maximum thrust therefrom on the rotor as a result of fluid flow thereagainst from one side of the axis of rotation of the rotor. The vane assembly displacement control structure includes an adjustment feature operative to effect simultaneous adjusted angular displacement of the vane assemblies relative to the corresponding mounting portions independent of rotation of the rotor and the adjustment feature includes fluid flow direction sensing structure operative to sense changes in the direction of fluid flow toward the axis of rotation of the rotor and to accordingly variously angularly position the vane assemblies about their axes of rotation relative to the mounting portions in order to maintain the optimumly angularly displaced positions thereof relative to the changed fluid flow direction. One disclosed form of the invention includes a control for the adjustment feature whereby the vane assemblies may be manually variously angularly positioned relative to the corresponding mounting portions of the rotor toward positions displaced relative to the direction of fluid flow against the rotor whereby the vane assemblies will be inoperative to drive the rotor. Further, a second form of the invention includes structure whereby the vane assemblies each comprise a plurality of vanes which may be remotely feathered toward positions parallel to the fluid flow acting upon the rotor.
