METHOD FOR CONVERTING AIRFLOW LOW-GRADE ENERGY

The way of transformation of low-potential energy of airflow is applicable in powerful helio-energy producing. The way is based on formation in a vertical airflow the concentrically located power channels by a partition rigid and massive wind turbine on a number independent sections due to installation in an airflow light concentric energy-differentiative bushes between which compound blades are established, for example, from sheet steel. Thus external surfaces of the energy-differentiative bushes, executed mainly also compound and facilitated, are strapped with bandage ropes, and on surfaces and-or inside blades are placed wing holding rods, the ropes perceiving on the basic loading from an air stream, influencing on easy compound blades. Wing holding rods or ropes are fixed with a prestressing is relative bandage surfaces of energy-differentiative bushes, and also in case of high specific power consumption of the wind turbine, applied additional cross-section together pulling ropes or the strengthening edges located on surfaces of wing blades perpendicularly to holding rods, ropes. By means of similar rods, the ropes located along forming surfaces of energy-differentiative bushes, in independent sections of the wind turbine is created presstressing, high-strength and light bearing rope or a rod design. Last provides an opportunity of achievement of the maximal linear and angular speeds of surfaces of energy-differentiative bushes. The energy-differentiative bushes mechanically incorporate to independent bearing of rotation. The way is based also on formation independent electrogenerating sections, replacing the single low-speed electrogenerator, connected by means of the named independent bearing of rotation and magnetic poles with corresponding energy-differentiative bushes, and electric coils with magnetic conducting systems are placed motionlessly concerning base. Such design of the wind-turbogenerator allows to reduce considerably the charge of ferrous metal, aluminium and copper, to lower the cost price and to raise reliability, and also maintainability of the installations realizing a way. In case of performance similar wind-turbogenerator the lowered or average capacity, can contain the energy-differentiative bush connected by means of components of blades and bearing prestressed rods with the second rotating bush on which poles of magnetic stimulating systems are fixed, and electric coils and magnetic conductors are placed on base in a free inter
