established a program for re designing the a f32t 9 exhaust augmenter shown in fig1 and the a f37t 10 exhaust augmenter similar to fig1 except without bolting flange 85 and the deflector a panel of which is shown in fig8 to extend service life cycle as will become clear to those skilled in the art embodiments configured according to teachings of the present invention are based upon concepts and technologies not included in current configurations notwithstanding underlying fundamental materials incorporated into embodiments of the present invention have been proven in other demanding applications such materials have been applied to embodiments for substantially increasing performance life of exhaust systems through application of a synergistic combination of proven specially selected and relatively inexpensive acoustic components esak embodiments have been designed in kit form to enable the objectives recited hereunder to be accomplished by proper installation of kits in the field or otherwise via maintenance protocols contemplated as already being in situ thus now referring to fig4 and 10 a layer of loose rolled basalt is installed at the bottom portion of an augmenter cavity this basalt roll is encapsulated with an acoustical blanket 26 next a high temperature acoustical pillow 45 is installed atop the acoustical blanket also referring to fig5 and 6 this pillow is then encapsulated with a stainless steel wire mesh screen 46.
