FIELD: power industry.
SUBSTANCE: group of inventions relates to a device for generation of energy from fluid medium and to a blade used in it, and can be used in particular in wind generators. A blade for the device for energy generation from fluid medium includes a guide surface inside which fluid medium shall move to rotate the blade about rotation axis Xo that together with axes Yo, Zo forms an orthogonal system of coordinates Xo, Yo, Zo. The above blade is restricted with front edge (4) and rear edge (5), constricted between front edge (4) and rear edge (5) and passes along midline (10). Projection of midline (10) onto plane Xo, Yo has the first curvature. Plane Xo, Yo is formed with a possibility of containing midline (10) at front edge (4).
EFFECT: group of inventions is aimed at improvement of output power of an energy generation device.
