Wind turbine rotor, wind turbine rotor module, wind panel with the wind turbine rotor module, method for manufacturing the wind turbine rotor

Apparatus comprising:

• a wind turbine rotor, wherein the wind turbine rotor
• is adapted to rotate about an axis of rotation,
• includes an axially elongated tube portion, wherein the tube portion includes
• an annular inner surface, wherein the inner surface bounds an inner space,
• an annular outer surface, wherein the outer surface includes
• a plurality of angularly spaced blades, wherein each blade comprises an axially elongated pleat,
• wherein in axially transverse cross-section each blade on the outer surface includes
• a longer wall and a shorter wall, wherein the longer wall
• extends through a longer outer wall angle on the outer surface that is larger than a shorter outer wall angle on the outer surface through which the shorter wall extends on the outer surface,
• extends on the outer wall surface between a first longer wall end and a second longer wall end, wherein the second longer wall end is disposed further radially outward from the axis of rotation than the first longer wall end,
• wherein the shorter wall
• extends on the outer wall surface between a first shorter wall end and a second shorter wall end,
• wherein the second shorter wall end corresponds to the second longer wall end of the longer wall of the respective blade, and the first shorter wall end corresponds to a first longer wall end of in immediately angularly adjacent blade that extends on the outer wall surface.
