A heat shield includes an inner portion, an outer portion, first and second insulating portions, and a deflecting portion. The inner portion includes a reflective material to reflect thermal energy that radiates from a heat/acoustic source. The outer portion includes a rigid material to provide structural support for the heat shield. The first and second insulating portions are intermediately positioned between the inner and outer portions. The deflecting portion is intermediately positioned between the first and second insulating portions to deflect acoustics from the heat/acoustic source. A method for manufacturing the heat shield is also disclosed.
L'invention concerne un écran thermique comprenant une partie interne, une partie externe, une première et une seconde parties isolantes, et une partie de déviation. La partie interne comprend un matériau réfléchissant afin de réfléchir l'énergie thermique qui rayonne depuis une source thermique/acoustique. La partie externe comprend un matériau rigide afin de fournir un support structurel à l'écran thermique. La première et la seconde parties isolantes sont en position intermédiaire entre les parties interne et externe. La partie de déviation est en position intermédiaire entre la première et la seconde parties isolantes afin de dévier les sons issus de la source thermique/acoustique. L'invention porte aussi sur un procédé de fabrication de l'écran thermique.
