Fluid flow turbines

摘要

A fluid flow turbine includes a rotor (5) and a first vane (1) having at least a part thereof positioned in front of the rotor (5) and having a tail extending towards the axis of the rotor (5). The first vane (1) serves to direct the fluid so as to flow to one side of the axis of the rotor (5), and a second vane (2) is positioned on the other side of the rotor (5). <IMAGE>
