FIELD: electrical engineering.
SUBSTANCE: method consists in that the turbine impellers are driven by wind flow entrapped by their surfaces and that reflected from the central unit and annular spinner. Note here that the guide vanes pre-spin the air flow for the impellers. The aforesaid annular spinner inner shape represents a widening nozzle, its front being furnished with the sail to entrap wind flows reflected from the landform and to form with the said sail the Laval nozzle inner section. The impellers and guide vanes are arranged right behind the nearest annular spinner section. The proposed device incorporates the turbine impellers and guide vanes driving the generator, the central unit arranged within the section of the guide vanes, the annular spinner representing the widening nozzle, its front being furnished with the sail to entrap wind flows reflected from the landform and to form with the said sail the Laval nozzle inner section. The sail lower part making an inner profile represents a flat surface, the impellers and guide vanes can be arranged in several rows to make a multi-stage turbine and the multi-stage generator is arranged below the sail and ahead of the impellers, the generators being fitted on the turbine shaft and coupled to the turbine by clutches as the wind power increases. The Laval nozzle critical section inlet features a variable shape due to a membrane or the central unit.
EFFECT: power generation in remote and hard-to-reach regions.
