Abstract

L'invention concerne un élément de retenue (22, 54) destiné à maintenir une tuile de protection thermique sur une structure support (43) au moyen d'au moins une portion de fixation (23) pouvant être fixée à la structure support et d'au moins une portion de retenue (24) dotée d'une tête de retenue (25) qui est conformée pour s'engager dans un dispositif d'engagement présent au niveau de la tuile de protection thermique. Dans le cas d'une portion de fixation fixée à la structure support (43) d'une portion de retenue s'engageant au niveau de la tuile de protection thermique, la portion de fixation (23) comporte un côté supérieur (28) dirigé vers le côté froid de la tuile de protection thermique. L'élément de retenue permet d'éviter de façon particulièrement efficace un calaminage de la structure support dû à l'aspiration de gaz chaud. Pour cela, la portion de fixation (23) comporte au moins un passage d'air de refroidissement (34 , 55) qui possède un orifice d'entrée (35 , 68) et au moins un orifice de sortie (37, 38, 62) ménagé dans une face latérale (32) et/ou sur le côté supérieur (28) de la portion de fixation. Le passage d'air de refroidissement permet d'imposer à l'air de refroidissement qui entre par l'orifice d'entrée (35, 68) et qui sort par le ou les orifices de sortie une direction d'écoulement (50, 51, 59, 63, 61) respective qui présente une composante de vitesse parallèle au côté froid et qui évite un refroidissement par impact de la tuile de protection thermique maintenue par la portion de retenue. Ici, la portion de fixation peut être disposée sur la structure support de telle sorte que le passage d'air de refroidissement (34, 55) correspond à au moins un conduit d'air de refroidissement (45) disposé dans la structure support.
