Abstract

"AERONAVE COM AEROFóLIOS AUXILIARES EMBUTIDOS SE ABRINDO PARA FRENTE PARA CONTROLE DE GUINADA" Uma aeronave (50) compreende uma primeira (68) e uma segunda (70) asas posicionadas em lados opostos de um eixo longitudinal, uma primeira superfície de controle se abrindo para frente (52) afixada a uma superfície superior da primeira asa (68), e uma segunda superfície de controle se abrindo para frente (54) afixada a uma superfície superior da segunda asa (70), onde cada uma das primeira (56) e segunda (58) articulações é inclinada (01, 02) com respeito a uma direção perpendicular a um eixo longitudinal da aeronave. Um método de provisão de controle de guinada de uma aeronave também é provido. o método compreende as etapas de provisão de um primeiro aerofólio auxiliar inclinado se abrindo para frente em uma superficie de topo de uma primeira asa da aeronave, provisão de um segundo aerofólio auxiliar inclinado se abrindo para frente em uma superfície de topo de uma segunda asa da aeronave, e operação dos primeiro e segundo aerofólios auxiliares diferentemente para a criação de um momento de guinada. A criação de momentos de guinada sem qualquer força para baixo tem aplicação em asas de envergadura flechada, em que as pontas estão atrás do centro de gravidade da aeronave. A vantagem está na redução da seção transversal de radar em relação a aerofólios auxiliares tradicionais (articulados para frente, abrindo-se para trás) em que deve haver um aerofólio auxiliar no lado de fundo para contrabalançar a força para baixo criada pelo aerofólio auxiliar de topo.
