Abstract

Turbina eólica de eixo vertical É descrita uma turbina eólica de eixo vertical, do tipo compreendendo uma torre (2, 2'), um eixo motor (5) vertical que conecta o rotor (20) a um gerador elétrico (4). A turbina compreende uma máquina eólica (10) composta por diversas unidades (11), empilhadas compondo uma coluna. Cada uma de ditas unidades (11) compreende um rotor eólico (20) disposto dentro de um módulo aerodinâmico (40), destinado a comprimir, acelerar e direcionar o fluxo de ar recebido externamente pelo dito módulo aerodinâmico (40) em direção ao dito rotor eólico (20). O módulo aerodinâmico (40) compreende uma superfície inferior (41) e uma superfície superior (42), ambas em forma de disco, centralmente vazadas, paralelas entre si e transversais em relação ao eixo de rotação do eixo motor (5). Entre as ditas superfícies (41, 42) é disposta uma pluralidade de defletores (43), paralelos entre si e transversais em relação as ditas superfícies (41, 42), dito defletores formando um ângulo em relação aos raios de ditas superfícies (41, 42). Os ditos defletores (43) se projetam desde a superfície inferior (41) até a superfície superior (42) e desde a borda externa (44) até a borda interna (45) a qual define a região cilíndrica sede para o rotor eólico (20). O rotor eólico (20) compreende uma base inferior (21) e uma base superior (22), ambas em forma de disco, paralelas entre si e transversais em relação ao eixo de rotação do eixo motor (5). Entre as ditas bases (21, 22) é disposta uma pluralidade de aletas (30), com formato de calota cilíndrica, as quais se projetam desde a borda externa (24) das ditas bases (21, 22) para o centro.Vertical Shaft Wind Turbine A vertical shaft wind turbine of the type comprising a tower (2 ', 2'), a vertical drive shaft (5) connecting the rotor (20) to an electric generator (4) is described. The turbine comprises a wind machine (10) composed of several units (11), stacked forming a column. Each of said units (11) comprises a wind rotor (20) disposed within an aerodynamic module (40) for compressing, accelerating and directing the air flow received externally by said aerodynamic module (40) towards said rotor. wind power (20). The aerodynamic module (40) comprises a lower surface (41) and an upper surface (42), both disc-shaped, centrally hollowed, parallel to each other and transverse to the axis of rotation of the driving axle (5). Between said surfaces (41, 42) are arranged a plurality of deflectors (43), parallel to and transverse to said surfaces (41, 42), said deflectors forming an angle with respect to the radii of said surfaces (41, 42). 42). Said deflectors (43) extend from the bottom surface (41) to the top surface (42) and from the outer edge (44) to the inner edge (45) which defines the seat cylindrical region for the wind rotor (20). ). The wind rotor (20) comprises a lower base (21) and an upper base (22), both disc-shaped, parallel to each other and transverse to the axis of rotation of the driving shaft (5). Between said bases (21, 22) are arranged a plurality of cylindrical cap-shaped fins (30) which project from the outer edge (24) of said bases (21, 22) to the center.
