Abstract
L'invention concerne écran (1) comprenant : une coque (2) thermo-comprimée à base de fibres liées entre elles par un liant thermoplastique, de manière à former une coque poreuse pourvue de propriétés d'absorption acoustique, ladite coque comprenant une face interne (3) et une face externe (4) ; une feuille (5) métallique de protection thermique vis-à-vis dudit moteur, ladite feuille recouvrant tout ou partie de ladite face interne, ladite feuille étant fixée par sa périphérie (6) de façon sensiblement étanche à ladite coque, ladite feuille présentant une pluralité de bossages (7) permettant de la maintenir généralement écartée de ladite face, de manière à créer une couche d'air (8) protégeant ladite coque de la chaleur accumulée par ladite feuille.
