Abstract
L'invention concerne un ensemble (2) pour turbomachine, comprenant : - un distributeur (3) annulaire par rapport à un axe (A) de révolution et comprenant une pluralité d'aubes (4) dont des faces (10) latérales adjacentes sont disposées bout à bout, ces faces (10) latérales comprenant des fentes (11) limitées par des parois, et situées en vis-à-vis dans les faces (10) latérales adjacentes de deux aubes (4) circonférentiellement successives, et - des plaquettes disposées individuellement dans les fentes (11) en vis-à-vis de deux aubes (4) circonférentiellement successives, les plaquettes étant courbées de sorte que, dans les fentes (11), les plaquettes soient déformées sous contrainte et retenues par pression sur les parois des fentes (11), caractérisé en ce que les fentes (11) présentent, selon un plan radial, un profil arqué.
