Rotor of a propulsive, wind driven machine - windmill

This invention contains description of rotor of propulsive machine, driven by wind which blows in approximatelly perpendicular direction to the machine's main shaft and where some elements of rotor are performing self-alining under infulence of wind.This invention complies with International Patent Clasification and is clasified under IPC F03D 03/06. This invention solves tehnical issue of design of a propulsive machine, driven by wind which blows in approximatelly perpendicular direction to the vertical machine's main shaft, and which has blades that constantly and automatically adjust their shape, under influlence of changeable angle between vectors of velocity of the wind and velocity of the blades. Propulsive wind driven machine is a device that transformes energy of natural wind into favorable mahanical energy, which is then trasfered to consumers. Rotor of machine of this kind is usualy equipped with several blades, that are subject to influence of wind. Rotor of propulsive wind driven machine is in the same way equipped with blades, similar to semi-circle shaped bins of an anemometer. Rotor of propulsive wind driven machine is distiguished by the fact that it's blades are built of two half-blades, whose relative position is self alining, depending on momentary angle between vectors of velocity of the wind and velocity of the blades, in other words they assemble-pack together during their movement against the wind, so their air drag is reduced.
