The invention relates to a turbine blade wheel for large water depths, the form of the cross-section of the wheel, comprising blades (4) and consisting of a part (7) that is straight or only slightly curved, being, under no circumstances, at a tangent to the outer circular part of the wheel, said cross-section also consisting of a curved part (8) for connection between parts (7) and (9). Said form, in association with the circular movement of the blades (R) as a result of the rotation of the wheel, follows a circular path of the incoming plane water jet, without hitting the other blades. |
