Abstract

Techniques for joining nodes and subcomponents are presented herein. An additively manufactured first node or subcomponent has a groove. An additively manufactured second node or subcomponent has a tongue configured to extend into and mate with the groove to form a tongue-and-groove connection between the first and second node or subcomponent. In some aspects, the tongue-groove connection may extend substantially around a periphery of the node or subcomponent. In other aspects, a first subcomponent having a fluid pipe interface may be coupled via a tongue-groove connection to a second subcomponent having a fluid pipe interface, thereby enabling fluid to flow between subcomponents of the resulting integrated component.

First claim

What is claimed is:

1. An apparatus, comprising:
an additively manufactured first subcomponent comprising a tongue structure; and
an additively manufactured second subcomponent comprising a groove structure configured to mate with the tongue structure,
wherein the first subcomponent includes a first fluid pipe interface,
the second subcomponent includes a second fluid pipe interface, and
the first fluid pipe interface is mated with the second fluid pipe interface to enable fluid flow between the first subcomponent and the second subcomponent.

2. The apparatus of claim 1 , wherein the tongue structure is mated with the groove structure to form the at least a portion of a component for use in a transport structure.

3. The apparatus of claim 2 , wherein the component comprises a gear case.

4. The apparatus of claim 2 , wherein the component comprises a load-bearing component.

5. The apparatus of claim 1 , wherein the tongue-and-groove structures are configured to seal a first peripheral region and a second peripheral region of the respective first and second subcomponents.

6. The apparatus of claim 2 , further comprising an adhesive applied between the tongue-and-groove structures.

7. The apparatus of claim 6 , wherein the adhesive is applied via a fill port providing a flow to a first area between the tongue-and-groove structures.

8. The apparatus of claim 7 , wherein the adhesive is drawn via a vacuum port to a second area between the tongue-and-groove structures distal from the first area.

9. The apparatus of claim 2 , further comprising a tongue centering feature disposed longitudinally within one side of the tongue structure.

10. The apparatus of claim 5 , further comprising first and second seal grooves disposed longitudinally along the first peripheral region adjacent first and second sides of the tongue structure, the seal grooves configured to accept a compliant seal.

11. The apparatus of claim 10 , further comprising at least one clamping feature disposed between the first and second peripheral regions and adjacent the first or second seal grooves, the at least one clamping feature configured to provide a void between edges of the first and second peripheral regions for preventing galvanic corrosion of dissimilar materials.

12. The apparatus of claim 11 , wherein the at least one clamping feature is removable.

13. The apparatus of claim 5 , further comprising at least one seal expansion void channel disposed longitudinally along the second peripheral region adjacent the groove structure.

14. The apparatus of claim 5 , further comprising at least one seal compression feature disposed longitudinally along the first peripheral region adjacent the tongue structure.

15. The apparatus of claim 5 , wherein the first and second peripheral regions comprise at least a portion of an outer wall of the gear case.

16. The apparatus of claim 1 ,
wherein the first fluid pipe interface includes a second tongue structure,
the second fluid pipe interface includes a second groove structure into which the second tongue structure is mated, and
wherein the second tongue-and-groove mated structures are sealed to enable the fluid flow between the subcomponents.

17. The apparatus of claim 1 ,
wherein the first fluid pipe interface includes a second groove structure,
the second fluid pipe interface includes a second tongue structure mating with the second groove structure,
wherein the second tongue-and-groove mated structures are sealed to enable the fluid flow between the subcomponents.

18. An apparatus, comprising:
an additively manufactured first subcomponent comprising a first outer wall and a first fluid pipe interface adjacent an edge of the first outer wall, the first fluid pipe interface comprising a first casing including a tongue structure extending outward relative to the edge of the first outer wall; and
an additively manufactured second subcomponent comprising a second outer wall and a second fluid pipe interface adjacent an edge of the second outer wall, the second fluid pipe interface comprising a second casing including a respective groove structure positioned to receive the tongue structure when the first and second subcomponents are joined,
wherein the first and second fluid pipe interfaces are sealed flush via a connection between the tongue-and-groove structures to enable fluid to flow between subcomponents.

19. The apparatus of claim 18 , wherein the tongue structure is disposed substantially around a periphery of the first casing.

20. The apparatus of claim 19 , wherein the groove structure is disposed substantially around a periphery of the second casing.

21. The apparatus of claim 18 , wherein the edge of the first outer wall is configured to join an edge of the second outer wall along a periphery of the first and second outer walls via a second tongue-and-groove connection.
