| 成果简介 | NOVELTY - Invention relates to wind power engineering, in particular to means of preventing and combating icing. Wind turbine blade consists of two casings, inner casing and outer casing. In the small volume of the blade, which is limited by the inner and outer casings, there is performed a pulse supply of the air flow directed from the blade base to its top. External casing of blade, at least in places most prone to icing, is made with perforations providing connection of specified small volume of blade with external surface. A blown fluoroplastic nonwoven material is fixed on the outer surface of the blade. Perforated second casing is designed to create air layer around outer surface of blade, preventing contact of said outer surface with outer incident flow perpendicular to blade. Layer of fluoroplastic nonwoven material is designed to create shock-wave action on formation of ice on the outer surface of the blade, as a result of pulsed supply of air flow into a small inner volume of the blade and provides a lower percentage of air moisture in the air layer around the outer surface of the blade than in the incoming air flow and its uniform distribution around the blade, its stability. Amplitude of airflow pulses is set by external control module depending on meteorological conditions. USE - Wind power engineering. ADVANTAGE - Prevention and control of wind turbine blades icing to improve its aerodynamic characteristics. 4 cl, 4 dwg |
