Abstract
A compartmentized muffler plug for the tail pipe of a jet engine is disclosed where the compartments are formed by conically shaped axially disposed partitions whose base bears against the wall of the plug and is in compression to accommodate radial growth and the sound suppression openings to the grazing flow are disposed to face the slanted walls of the partition to enhance sound suppression.
