an existing structural acoustic splitter 11 as a result of these structural alterations there is eliminated the need for the flowpath fairing support and stator case stiffener 3 being of full hoop construction the structural acoustic splitter 11 improves lpc case concentricity resulting in longer performance retention extending the flowpath fairing 1 to form structural acoustic splitter 11 also improves noise attenuation via an increase in acoustically treated surface area in a preferred embodiment low compressor bleed exhaust ports 2 are periodically cut through the structural acoustic splitter 11 by doing so the metallic structure and bolts supporting these ports are eliminated low compressor bleed exhaust ports 2 may be glued in from the inner or outer diameter bolted in or otherwise fastened to structural acoustic splitter 11 the structural acoustic splitter 11 can still accommodate thermal growth along the engine axis by including an aft slip joint 21 at the fegv interface 9 positive circumferential radial and axial restraint is still maintained by the conventional bolted joint 10 with reference to fig3 there is illustrated in detail an aft slip joint 21 in accordance with the present invention aft slip joint 21 is formed from full hoop slot 31 into which is inserted an end of structural acoustic splitter 11 surrounding the end of structural acoustic splitter 11 and in contact with an inner surface 37 of full hoop slot 31 there is dispersed a sacrificial wear material 33 as structural acoustic splitter 11 undergoes thermal expansion and contraction it slides forwards and backwards inside of full hoop slot 31 sacrificial wear material 33 serves to prevent.
