초록

An acoustic muffler for a turbine engine exhaust comprises an outer shell of tubular configuration, a tubular liner disposed within the shell, and a plurality of dividing walls extending between the liner and the outer shell so as to divide the generally annular space between the liner and shell into a plurality of chambers circumferentially spaced about the muffler. A central longitudinal axis of the liner is radially offset from the central longitudinal axis of the shell such that the chambers have different depths in a radial direction of the muffler,...
