Method for installing and removing modularized silencer baffles

1. A method, comprising:

assembling a plurality of baffle sections in first and second directions to form a silencer baffle configured to mount in a fluid conduit along a fluid flow path, wherein assembling the silencer baffle comprises:

arranging the plurality of baffle sections in the first direction along at least one rod extending through an interior surrounded by a baffle shell of each baffle section of the plurality of baffle sections;

coupling together the plurality of baffle sections against one another in a plurality of rows via mating interlock structures along opposing sides of adjacent baffle sections of the plurality of baffle sections, wherein each row of the plurality of rows is oriented in the second direction, wherein coupling together the plurality of baffle sections comprises slidingly engaging the mating interlock structures of the adjacent baffle sections of the plurality of baffle sections in the first direction such that the opposing sides move parallel to one another, and the mating interlock structures block separation of the adjacent baffle sections in the second direction crosswise to the first direction; and

stacking the plurality of baffle sections against one another in the first direction in a plurality of columns crosswise to the plurality of rows, wherein the first direction is oriented along an axis of each column of the plurality of columns.

2. The method of claim 1 , wherein arranging the plurality of baffle sections in the first direction along at least one rod comprises arranging the plurality of baffle sections along an axis of the at least one rod.

3. The method of claim 1 , wherein assembling the silencer baffle comprises stacking the plurality of columns of baffle sections along the at least one rod, and coupling together the plurality of rows of baffle sections via the mating interlock structures.

4. The method of claim 1 , comprising installing the silencer baffle inside the fluid conduit, and coupling the at least one rod to opposite first and second panels of the fluid conduit.

5. The method of claim 1 , wherein coupling together the plurality of baffle sections comprises forming an airfoil shape of the silencer baffle, wherein the second direction extends from a leading edge to a trailing edge of the airfoil shape, wherein the first direction extends along the leading edge.

6. The method of claim 1 , wherein the silencer baffle comprises a pattern along an exterior surface of one or more of the plurality of baffle sections, and the pattern has a plurality of openings, a plurality of recesses, a plurality of protrusions, or a combination thereof.

7. The method of claim 1 , wherein each baffle section of the plurality of baffle sections has a sound absorption material disposed within an outer shell.

8. The method of claim 1 , comprising:

inspecting the silencer baffle after installation in the fluid conduit; and

servicing, repairing, or replacing one or more baffle sections of the plurality of baffle sections of the silencer baffle.

9. The method of claim 1 , wherein arranging the plurality of baffle sections in the first direction along at least one rod comprises inserting a first rod in the first direction through a first rod passage in each baffle section of a first series of baffle sections of the plurality of baffle sections.

10. The method of claim 9 , wherein arranging the plurality of baffle sections in the first direction along at least one rod comprises inserting a second rod in the first direction through a second rod passage in each baffle section of a second series of baffle sections of the plurality of baffle sections, and the first and second rods are laterally offset from one another in the second direction crosswise to the first direction.

11. The method of claim 1 , wherein coupling together the plurality of baffle sections comprises coupling together male and female joint portions of the mating interlock structures of adjacent baffle sections of the plurality of baffle sections in the first direction.

12. The method of claim 11 , wherein the male and female joint portions comprise male and female rail portions, male and female dovetail joint portions, or a combination thereof.

13. The method of claim 1 , wherein coupling together the plurality of baffle sections comprises coupling together a leading edge baffle section and a trailing edge baffle section in the first direction.

14. The method of claim 13 , wherein coupling together the plurality of baffle sections comprises coupling together one or more intermediate baffle sections between the leading and trailing edge baffle sections in the first direction.

15. The method of claim 1 , comprising installing the silencer baffle in the fluid conduit coupled to a machine.

16. The method of claim 15 , wherein the machine comprises a turbine engine.
