Abstract

Un silencieux d'échappement (15) d'une unité de puissance auxiliaire (APU) comprend des caractéristiques de refroidissement pour protéger le revêtement externe (14) et d'autres composants de la chaleur générée par les gaz passant par un conduit d'échappement (20). L'écoulement d'air de refroidissement à travers un passage d'air de refroidissement (28) en contact thermique avec le silencieux d'échappement (24) éloigne la chaleur des autres composants à proximité et du revêtement de l'avion.
