Abstract

"CUBO DE RODA DE ROTOR EM PLANO MACIO". Uma montagem de cubo de roda de rotor para uma aeronave de asa rotativa tem um membro central e uma pluralidade de garras de lâmina adaptadas para fixação da lâmina do rotor ao membro central. As garras de lâmina são articulavelmente fixadas ao membro central, e são capazes de articularem sobre um eixo geométrico de articulação geralmente normal a um plano de rotação das lâminas. A articulação permite movimento em plano das lâminas em relação ao membro central. Um amortecedor é operavelmente conectado a cada garra de lâmina para amortecimento do movimento em plano da lâmina associada, cada amortecedor sendo seletivamente comutável entre pelo menos duas taxas de mola.
