A centerbody for a gas turbine engine includes a thermal control system which minimizes the thermal stresses between the centerbody and at least one stiffener. The centerbody stiffener extends radially inward from a centerbody shell. A cavity is defined within each centerbody stiffener. The thermal control system includes a plurality of openings circumferentially disposed around the centerbody. Each opening extends through the centerbody shell into each cavity. The openings include pairs of entrance openings and exit openings which permit circumferential flow to develop within the centerbody cavity.

The method set forth in claim 1, further comprising the step of: providing inclined edges at the distal end of the rail to permit the slider member to taper inwardly toward the relaxed position as the slider member is discharged from the distal end of the rail. 8. The method set forth in claim 1, further comprising the step of: reducing the height of the rail at the distal end thereof to permit the rail to be received between the intermediate body portion and the side walls as the slider member is discharged from the distal end of the rail. 9. The method set forth in claim 1, further comprising the step of: providing an opening in a top portion of the rail at the distal end thereof to permit a separator finger projecting downwardly from the intermediate body portion of the slider member to be at least partially received between the interlocking fastening strips as the slider member is discharged from the distal end of the rail. 10. The method set forth in claim 1, further comprising the step of: providing a tool above the rail to obstruct the slider member from becoming disengaged with the rail as the side walls of the slider member are being resiliently spread apart. 11. The method set forth in claim 10, wherein the step of providing a tool above the rail to obstruct the slider member from becoming disengaged with the rail as the side walls of the slider member are resiliently spread apart comprises: positioning the intermediate body portion of the slider member between the rail and the tool. 12. An apparatus for assembling resilient slider members onto interlocking fastening strips, the slider members each having a pair of spaced-apart side walls and an intermediate body portion therebetween, the apparatus comprising: a rail for a slider member which converges with interlocking fastening strips at a distal end thereof; the apparatus moves the slider member along the rail toward the distal end thereof; the apparatus spreads apart the side walls of the slider member to accept the interlocking fastening strips therebetween as the slider member is moved along the rail toward the distal end thereof; the apparatus returns the spread apart side walls of the slider member to a relaxed position, the side walls are positioned to obstruct removal of the slider member from the interlocking fastening strips, as the slider member reaches the distal end of the rail; and the apparatus discharges the slider member from the distal end of the rail to assemble the slider member onto the interlocking fastening strips. 13. The invention set forth in claim 12, wherein the rail is generally U-shaped and the side walls of the slider member engage respective side portions of the generally U-shaped rail. 14. The invention set forth in claim 13, wherein each side wall has a shoulder and the shoulders of the slider member engage respective side portions of the generally U-shaped rail. 15. The invention set forth in claim 12, wherein the distance between respective side portions of the rail widens to provide a gap between the side walls which is large enough to receive the interlocking fastening strips therebetween. 16. The invention set forth in claim 15, wherein the distance between the side portions of the rail progressively widens as the rail converges toward the interlocking strips. 17. The invention set forth in claim 12, wherein the distance between respective side portions of the rail narrows to provide a gap between the side walls which is small enough to obstruct removal of the slider member from the interlocking fastening strips. 18. The invention set
