Claim 0:
1. A flow turbine rotor comprising:
a shaft (3); and
rotor blades (1) with aerodynamic profiles defining leading and trailing edges,
the rotor blades (1) coupled to the shaft (3) via a mount (4) and extend in twisted manner from the mount (4) in such a way that a twist of the rotor blades (1) around the shaft (3) varies with a height of the rotor blades (1);
an angle α, measured as an angular deviation along a rotational direction of the shaft (3) between an angular position of a trailing edge of a respective rotor blade of the rotor blades (1), at a height h1/4 along the shaft (3) located on ¼ of a length H of the shaft (3), measured parallel to the shaft (3) from the mount (4) of the shaft (3), and an angular position of the trailing edge of the respective rotor blade of the rotor blades 1, at a height h1/2 along the shaft (3) located on ½ of the length H, measured parallel to the shaft (3) of the flow turbine rotor, is at least 20 percent smaller, than an angle β, measured as an angular deviation along the rotational direction of the shaft (3) between the angular position of the trailing edge of the respective rotor blade of the rotor blades (1), at the height h1/2 corresponding to ½ of the length H measured parallel to the shaft (3) of the flow turbine rotor, and the angular position of the trailing edge of the respective rotor blade of the rotor blades (1), at a height h3/4 along the shaft (3) located at ¾ of the length H of the shaft (3), measured parallel to the shaft 3 of the flow turbine rotor.
