The present invention relates to a rotating blade body (10) for turbines using the Magnus effect (20) 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 (11), more distant from said axis of rotation of the turbine, and by a second sector (12), connecting said first sector (11) and said axis of rotation of the turbine, said first sector (11) being circumscribed within a first ovoid of construction of Rankine-Fuhrman, with minor axis (D 1 ) comprised between 1/5 and 1/6 of the diameter (Ø) of the turbine axis and with major axis (L 1 ) equal to 10 times said minor axis (D 1 ), said first sector (11) having a larger diameter at its point farthest from said axis of rotation of the turbine and equal to D 1 and length at least equal to said larger diameter; said second sector (12), of connection between said first sector (11) and said axis of rotation of the turbine, being circumscribed within a second ovoid of construction of Rankine-Fuhrmann, with a major axis (L 2 ) corresponding to the diameter (Ø) of the turbine and with minor axis (D 2 ) equal to 1/10 of said major axis (L 2 ), said second sector (12) having a larger diameter at its point farthest from said axis of rotation of the turbine and a length equal to the distance between said first sector (D 1 ) and said axis of rotation of the turbine.
