A wind power rotor has a first and second rotor device. The first rotor device rotates about a first axis of rotation and has at least two rotor blades moving on a peripheral track about the first axis of rotation. The rotor blades are such that they describe a virtual first shell surface of a virtual first rotating body upon rotation about the first axis of rotation. The second rotor device rotates about a second axis of rotation and has a second rotating body with a closed second shell surface. The second rotating body is arranged at least partially inside of the virtual first rotating body. The first rotor device can be driven by wind in a first direction of rotation and the second rotor device has a drive device, and can be driven in a second direction of rotation which is opposite that of the first direction of rotation.

The present invention relates to a rotating blade body for turbines using the Magnus effect with an axis of rotation of the turbine parallel to the direction of the motor fluid, characterised in that it is defined by a first sector or end head, more distant from said axis of rotation of the turbine, and by a second sector or rod, connecting said first sector and said axis of rotation of the turbine, said second sector having an average diameter smaller than the diameter of said first sector, said first sector being inscribed within a solid of revolution whose profile is determined so as to maintain a constant value of lift in each section.

A sectorized nozzle for a turbine engine turbine including an inner sectorized annular platform and an outer sectorized annular platform connected together by radial airfoils, at least one of the platforms including a plurality of orifices for passing air in a neighborhood of its upstream end, the orifices being distributed over the circumference of the platform and opening out at their ends remote from the airfoils into a circumferential annular cavity of the sector of the platform, which cavity is closed by a metal sheet fastened to the platform sector and pierced by orifices for feeding cooling air.

An energy generating device for generating energy from a flowing fluid, especially from a wind flow and/or from a water flow, comprises: a rotation body, the rotation body extending along an axis of rotation between a first point and a second point and the rotation body being adapted to rotate about the axis of rotation and the rotation body being formed from at least a first, a second, and a third rotation segment, wherein the rotation segments are joined together and arranged along the axis of rotation, and they form a region at least partly surrounded by fluid, wherein the second rotation segment is situated between the first and the third rotation segment and has a different diameter than the first and third rotation segment; and a generator device mechanically connected to the rotation body, wherein the generator device is adapted to generate energy which is produced from the rotation of the rotation body.
