A wind powered turbine comprises a plurality of vanes 1 tangentially angled about the axis 2 of a drum-like frame. The frame is arranged to rotate about its longitudinal axis 2 and it has a tubular member 5 mounted co-axially with the longitudinal axis 2, within the path swept by the vanes 1 as they rotate. The tubular member 5 constrains the wind to follow an arcuate path between entry and exit points where it reacts with the vanes 1 of the turbine.

A wind powered turbine for driving an engine, comprising a plurality of aerofoil section vanes tangentially angled about a longitudinal axis of a drum-like frame arranged to rotate in a path about its longitudinal axis and having a cylindrical member mounted co-axially with the longitudinal axis and within the path swept by the vanes as they rotate, wherein the vanes are adjustable between a first position at which leading and trailing edges of each vane are at substantially the same distance from the shaft so as to form a substantially closed cylinder, and a second position in which vanes moving into wind add to the rotational forces on the turbine by means of an aerofoil effect, and in which the leading edge of a vane moving into the wind is closer the cylindrical member than the trailing edge so that the vanes cooperate with the cylindrical member to constrain the wind to follow an arcuate path between entry and exit points where it reacts with the vanes of the turbine, each vane having an intermediate region between its leading and trailing edges, and each vane being tapered from its intermediate region to its trailing edge such that the vane has a greater cross-section at its intermediate region than at its trailing edge.
