Abstract

This invention relates to a turbine arrangement (10) and an aerofoil blade arrangement (20) for a fluid driven turbine. The aerofoil arrangement includes a primary aerofoil blade (21) which is displaceably securable relative to a hub (12) of the turbine in order for the primary aerofoil blade to be rotatable about an axis perpendicular to a rotational axis of the hub; and a secondary aerofoil blade (23) which extends from the primary aerofoil blade (21). The secondary aerofoil is securable in a fixed position relative to the primary blade, so that displacement of the secondary aerofoil blade results in rotation of the primary aerofoil blade, in order for the secondary aerofoil blade to control an angle of attack of the primary aerofoil blade to an optimum angle.
