Abstract

HéLICE AXIAL COM FLUXO OTIMIZADO. Uma hélice axial (1), com fluxo otimizado, girando em um plano (XY) em tomo de um eixo geométrico (2) compreende um cubo central (3), cujo diâmetro e menor do que o diâmetro do motor de condução (3a), uma pluralidade de lâminas (4) possuem uma base (5) e uma ponta (6), as lâminas (4) sendo delimitadas por uma borda de condução convexa (7) e por uma borda de cauda convexa (8), cujas projeções no piano de rotação da hélice são cada uma definidas por segmentos de arco circular; as lâminas (4) são compostas de seções que possuem perfis aerodinâmicos (18) cada uma possuindo uma diminuição do comprimento e um aumento da forma curvada começando na borda em direção ao cubo; em direção ao cubo cada lâmina (4) possui uma porção em forma de caixa (20) que forma um amplo assento (21) provendo o alojamento para um motor de condução (3a) possuindo um diâmetro que corresponde substancialmente ao assento (21).
