Abstract

Flexible blades 2, on a turbine, allow the turbine to rotate in the same direction, even if the flow is reversed. An example of its use is in a wave generator, where a water wave forces air backwards and forwards through the turbine, rotating it in one direction only. Another example of its use is to affix the blades to a vehicle's wheels. This is stated to have the effect of assisting or driving the vehicle forward with the wind blowing through the wheel from either side of the vehicle.

Description

Uni-directional Turbine
Description
The Turbine has blades that are flexible. The blades flex or bend with the direction of fluid passing through the turbine, either directly through or in the opposite direction. The blades flex to such a degree that a rotational force is exerted on the Turbine shaft or axle.
The turbine solves the problem that a fixed blade turbine will reverse its rotation when the fluid flow is reversed. The Uni-directional turbine has an advantage in that the Inertia of the rotating turbine continues in the same direction with the reversal of fluid flow.

    Uni-directional Turbine Claims Flexible turbine blades rotate the turbine in one direction, whether the fluid flow through the Turbine stays the same or flows in the opposite direction.
