Rotor has disk and ring, which are connected through planks. Ring is made in the form of flat rim. Blades are pivotally attached to rotor by means of axially aligned fingers for rotation around axis defined by pivot joint fingers. Upper finger is positioned in upper part of blade and in disk opening with its threaded portion and is fixed on disk by nut. Lower finger is positioned in blade mid portion and is extending through opening in flat rim of rotor ring. Each blade is fixed by means of stop screw with nut attached on disk lower surface. Disk and ring with blades are positioned for rotation by shaft mounted on bearings in casing and connected to drive mechanism and to split bushing secured on disk and put onto shaft at side opposite to drive mechanism. Bearings and casing are arranged above said disk and ring with blades to define load feeding zone inside blades. EFFECT: increased efficiency and reduced power consumption. 5 dwg
