Abstract

[0001] resumo patente de invenção: "tira de proteção multifuncional contra erosão". a presente invenção refere-se um artigo de perfil aerodinâmico que inclui um revestimento compósito (5) que tem uma primeira superfície (s1) e uma segunda superfície (s2) oposta à dita primeira superfície, formando uma borda dianteira (4). a borda dianteira (4) é, durante a sua utilização, submetida a um fluxo de ar (a) de encontro à borda dianteira (4) em pontos de estagnação (sp). a borda dianteira (4) compreende um membro alongado (9, 9'...9''''', 30, 32, 36, 38, 39). a superfície externa (o) do membro alongado está disposta nivelada com a primeira superfície (s1) do revestimento compósito (5), de tal modo que uma superfície aerodinâmica essencialmente lisa da borda dianteira (4) é formada. o membro alongado é adaptado para servir de proteção contra a erosão da borda dianteira e para funcionar como um eletrodo (ca, er) de um sistema de geração de plasma (40).
