Abstract

turbo-máquina, e, aeronave. uma cascata (80) para um dispositivo reversor de empuxo destinado a ser montado em uma turbomáquina de uma aeronave, a cascata (80) incluindo primeiras partições (82) se estendendo em uma primeira direção (da), segundas partições (83) se estendendo em uma segunda direção (dc) ortogonal à primeira direção (dc), as segundas partições (83) se estendendo em uma terceira direção (dr) secante a um plano que compreende primeira e segunda direções (da e dc) entre uma primeira e uma segunda extremidade (85 e 86). cada segunda partição (83) forma, com planos de referência (pr) paralelos à segunda direção (dc) e à terceira direção (dr), uma pluralidade de ângulos diferentes ( 1 a 4) em posições (h1 a h4) distintas da altura (h) das segundas partições (83) separando a primeira extremidade (85) da segunda extremidade (86) das segundas partições (83), cada ângulo ( 1 a 4) sendo formado entre um plano de referência (pr) e a tangente à segunda partição (83) tomada na interseção entre o dito plano de referência (pr) correspondente e a segunda partição (83) na posição (h1 a h4) da altura (h) da segunda partição (83) correspondente.
