Description
“POTENCiALiZADOR NATURAL PARA PÁS AERADAS EM HELICES DE GERADORES EÓLICOS” [01] A presente patente de invenção refere-se a potencializador para pás de hélices aeradas em geradores eólicos proporcionando maior rotação por minuto “RPM” e aumento da força mecânica nas mesmas. Geradores de energia eólica são conhecidos tipicamente por grandes hélices com pás grandes e longas, e que são ocas devido sua forma construtiva em resinas de alta resistência como epóxi ou fiberglass, muito mais leves, mais flexíveis e baratas. [02] Esta invenção tem na borda de ataque das pás furos para entradas de ventos que são conduzidos por dutos internos, atravessando toda a largura das pás e saindo pelo borda de fuga em sua traseira fazendo com que os ventos que por ali passam aumentem a velocidade em RPM. [03] Uma das vantagens deste tipo de inovação é que alem de melhorar o desempenho da hélice também minimiza o efeito de turbulência que prejudica o fluxo dos ventos porque distribuem melhor o fluxo de ar toda seu comprimento aliviando inclusive o estresse mecânico nas pontas das pás, que é muito forte sempre devido ao seu grande comprimento razão que permitira maior RPM. [04] Este sistema poderá ser aplicado tanto em hélices de novas torres eólicas como nas já existentes e neste caso as pás da hélice deverão ser trocadas por novas já incorporando a entrada e saída dos ventos da mesma no sistema acima explicado. [05] De acordo com as ilustrações anexas e seus pormenores a captação dos ventos e sua distribuição, mostram bem o efeito que causam modificando assim seu desempenho de velocidade e força, sendo todo o sistema mostrado e suas particularidades nas figuras a seguir. [06] Figura 1. - mostra uma pá de hélice de torres eólicas em visão frontal, detalhando como corre o duto internamente da mesma, mostrando a entrada e saída dos ventos. [07] Figura 2. - mostra que externamente acompanhando o duto interno tem uma ranhura ondulada que também vai auxiliar na condução dos ventos externos. [08] Figura 3. mostra bem a entrada dos e saída dos ventos internos e externos, [09] Figura 4 mostra a saída dos ventos na linha do borda de fuga das pás. [10] Figura 5 mostra a entrada dos ventos na dianteira das pás ou borda de ataque e com isto impulsiona as pás de hélice para frente aumentando assim sua velocidade e conseqüentemente sua potência. [11] De acordo com as ilustrações anexas e seus pormenores as pás (1) do gerador eólico (não mostrado) possuírem internamente dutos (2) dispostos transversamente em relação à pá, sendo dotados de entrada (3) e saída (4) do fluxo de ar. [12] Os dutos (2) podem estar dispostos em ângulo em relação à pá conforme mostrado nas figuras 1 e 2 sendo este ângulo positivo ou negativo ou ainda o duto (2) pode atravessar a pá (1) de forma reta. [13] A pá pode ser dotada ainda de ranhuras externas (5) em um ou nos dos lados preferivelmente acompanhando cada um dos dutos internos (2) [14] Com o aumento do fluxo de ar a partir dos dutos (2) e das ranhuras (5) a pá aumenta sua eficiência energética. [15] Na forma exposta e proposta por esta patente de invenção, este dispositivo inovador de baixo custo na sua construção e simplicidade se justifica pelo desempenho que poderá ser alcançado."NATURAL POTENTIALIZER FOR AERIAL BLADE SHIELDS IN WIND GENERATOR HELICES" [01] The present invention relates to wind turbine blade propellant enhancer in wind generators providing greater "RPM" rotation per minute and increased mechanical force therein. Wind power generators are typically known for large propellers with large and long blades, which are hollow due to their constructive shape in much lighter, more flexible and cheaper high strength resins such as epoxy or fiberglass. [02] This invention has at the leading edge of the blades holes for wind inlets that are driven through internal ducts, traversing the full width of the blades and exiting the trailing edge at its rear causing the passing winds to increase the speed. speed in rpm. [03] One of the advantages of this type of innovation is that in addition to improving propeller performance it also minimizes the turbulence effect that impairs wind flow by better distributing air flow over its entire length while relieving mechanical stress on the blade tips. which is very strong always due to its large length ratio which will allow higher RPM. [04] This system can be applied to both new and existing wind tower propellers and in this case the propeller blades should be replaced with new ones incorporating the wind in and out of the propeller in the system explained above. [05] According to the accompanying illustrations and their details, the wind uptake and its distribution clearly show the effect they have on modifying its speed and strength performance, the whole system being shown and its particularities in the following figures. [06] Figure 1. - Shows a propeller blade of wind towers in front view, detailing how the duct runs internally, showing the entry and exit of winds. [07] Figure 2. - shows that externally accompanying the internal duct has a corrugated groove that will also assist in driving the external winds. [08] Figure 3. shows well the inlet and outlet of internal and external winds, [09] Figure 4 shows the outlet of winds at the trailing edge line of the blades. [10] Figure 5 shows the entry of winds at the front of the blades or leading edge and with this propels the propeller blades forward thus increasing their speed and consequently their power. [11] According to the accompanying illustrations and their details the blades (1) of the wind generator (not shown) have internally ducts (2) disposed transversely to the blade and are provided with inlet (3) and outlet (4) of the air flow. [12] The ducts (2) may be arranged at an angle to the blade as shown in figures 1 and 2 with this angle being positive or negative or the duct (2) may cross the blade (1) straight. [13] The blade may also be provided with external grooves (5) on one or both sides, preferably accompanying each of the internal ducts (2) [14] With increased air flow from the ducts (2) and slots (5) the blade increases its energy efficiency. [15] In the form set forth and proposed by this patent, this innovative low cost device in its construction and simplicity is justified by the performance that can be achieved.
