Abstract

A flexible muffler for use in an aircraft environmental system includes a flexible body having a porous inner layer and an air impervious outer layer both supported by a helically wound adhesively attached reinforcing cord. The flexible body includes a pair of connecting end caps at opposed ends thereof which are joined to the flexible body in an air tight attachment. The resulting muffler provides acoustic energy absorptive and is readily flexed and bent to accommodate space restrictions within the environmental control system of the aircraft.
