Abstract

<B>"ROTOR DE HELICóPTERO DE úNICA Pá"<D>. A presente invenção descreve um rotor principal de única pá para helicópteros projetado de forma que o componente de elevação da pá normal ao eixo de rotação do rotor, é compensado através da força de inércia obtida através do ajuste automático da posição do centro do rotor de massa relativo ao seu eixo de rotação, este sendo fornecido com a posição do centro do rotor de massa, que é determinada pelo ângulo de conicidade da pá.
