Abstract

<B>AERONAVE AEROFLUTUANTE<D> Em uma nova aeronave aeroflutuante, uma estrutura de hélices de aerofólio girável em torno de um eixo vertical compreende um conjunto de hélices superiores (30, 32, 34) e um conjunto de hélices inferiores (36, 38), todas tendo força de sustentação variável, as hélices superiores convergindo em direção às hélices inferiores a partir da base até a ponta. Longarinas (84), localizadas no interior das pontas das hélices, mantém as pontas das hélices superior e inferior separadas entre si para reduzir os efeitos de interferência, e também sustentam os motores (74, 76) e os propulsores.
