Abstract

Novelty: Replacement of sailcloth blades (1) with new-technology perforated polyester fabric blades (3) practicable for windmills. Purpose: Protection of wind mills from strong winds; avoidance of tiresome daily works (folding and deployment of sailcloth blades); service life of blades increased by four times.
