The invention relates to a turbine or propeller aggregate of the type comprising at least two rotors provided with blades, the rotors being completely surrounded by a fluid and arranged to rotate simultaneously around both their respective axes crosswise to the plane of rotation and a common central axis of rotation for the rotors, parallel to the plane of rotation. The object of the invention is to provide a constructively simple and sturdy turbine or propeller aggregate, which in comparison with known aggregates will be cheap in manufacture and have a high efficiency. These objects are met in that the blades 10, 11 of the rotors 9 are essentially planar and arranged in tandem and at an angle of 90 degrees relative to each other in pairs, and that the blades of the rotors 10, 11 are laterally reversed relative to each other in two positions of rotation during the course of a revolution, both around their axes of rotation 13 and around the common central axis 14. <IMAGE> |
