Abstract
Un ensemble (10) d'affaiblissement d'ondes de choc et d'ondes acoustiques, composé d'écrans poreux (12), forme une enceinte remplie d'un milieu ou d'un matériau (14) d'affaiblissement d'ondes de pression approprié présentant des caractéristiques coulantes. La configuration de base peut être suspendue ou maintenue en place par une structure rigide (16). Lorsque le milieu (14) d'affaiblissement de pression est un liquide, l'ensemble (10) d'affaiblissement est pourvu d'un revêtement interne (30) destiné au confinement du liquide. Plusieurs ensembles (10) d'affaiblissement peuvent être utilisés, des ensembles adjacents étant séparés par une petite fente (40). Le milieu (14) d'affaiblissement peut être un liquide, une émulsion gazeuse, une mousse aqueuse ou un gel (avec ou sans gaz entraîné). Selon une variante, des matières particulaires solides (62) présentant les caractéristiques mécaniques en masse d'un fluide, peuvent être utilisées comme milieu d'affaiblissement d'ondes de pression, et peuvent comprendre un adhésif ou autre opposant une résistance au mouvement relatif des particules (62) afin de simuler des effets de viscosité. Des éléments de l'ensemble peuvent comprendre des matières absorbant l'énergie thermique par l'intermédiaire de réactions chimiques endothermiques, telles que des matières intumescentes augmentant l'effet d'affaiblissement de pression.
