Abstract
formas de realização de um rotor de tubos de espuma de múltiplos diâmetros (10) incluem um primeiro conjunto de fendas radialmente afastadas, estendendo-se longitudinalmente (11a) localizadas em direção a uma extremidade do nariz (13) do rotor de tubos e um segundo conjunto de fendas afastadas radialmente, que se estendem longitudinalmente (11b) localizadas na direção de uma extremidade da cauda (23). cada conjunto de fendas termina em uma seção de banda (15a; 15b) do rotor de tubos, de modo que, em conjunto, os dois conjuntos de fendas não atravessem todo o comprimento do rotor de tubos. uma versão unitária de comprimento padrão do rotor de tubos de espuma inclui apenas o primeiro conjunto de fendas (11a). um conjunto de fendas intermediárias mais curtas, deslocadas em uma direção circunferencial dos primeiro e segundo conjuntos de fendas e parcialmente sobrepondo essas fendas, pode ser incluído na seção de banda. devido às fendas, e devido à espuma de células abertas, o rotor de tubos de espuma diminui ou aumenta de diâmetro à medida que entra em um trecho de diâmetro diferente do trecho que acabou de ser percorrido.
