Abstract
BIPLANO TANDEM COM FUSELAGEM DE PISO MúLTIPLO. Refere-se a presente patente de invenção a uma aeronave com duas asas, sendo uma asa montada abaixo e na parte dianteira, e a outra asa montada acima e na parte traseira, de uma fuselagem de piso múltiplo formada pela união de dois ou mais de dois corpos alongados superpostos verticalmente de modo a aumentar o entreplano ou separação vertical entre as asas, e assim reduzir a interferência aerodinâmica e o arrasto induzido das mesmas, bem como: a) obter reduções da ordem de trinta por cento tanto na envergadura da aeronave facilitando a sua hangaragem e manobrabilidade no solo, como no peso da estrutura primária das asas. b) obter uma redução no peso da estrutura primária da fuselagem pelo seu apoio duplo em duas asas, sua maior altura, e devido aos menores raios de suas superfícies externas. Reduções estas tomadas em comparação com um monoplano equivalente com o mesmo valor de superfície total de asa, e com uma fuselagem circular de mesma seção transversal.TANDEM BIPLANO WITH MULTIPLE FLOOR FUSELING. The present invention relates to a two-winged aircraft, one wing being mounted below and at the front, and the other wing mounted above and at the rear, of a multi-floor fuselage formed by joining two or more of two elongate bodies superimposed vertically to increase the wingspan or vertical separation between the wings, thereby reducing the aerodynamic interference and the induced drag of the wings, as well as: a) to obtain reductions of the order of thirty percent in both the wingspan of the aircraft facilitating its hangarage and maneuverability on the ground, as in the weight of the primary wing structure. b) obtain a reduction in the weight of the primary fuselage structure by its double support on two wings, its higher height, and due to the smaller radii of its outer surfaces. Reductions take these compared to an equivalent monoplane with the same total wing surface value, and with a circular fuselage of the same cross section.
