ADJUSTABLE INSERT FOR SANDWICH STRUCTURES

摘要

An insert for use in a sandwich-type structure, such as a honeycomb panel, is provided that includes a plug and a sleeve. The sleeve includes a plurality of resilient beams, and when the plug is inserted into the sleeve, the resilient beams are elastically deflected by an exterior surface of a wall of the plug such that the insert is adjustable in height and can be positioned properly in an axial/insertion direction to accommodate sandwich-type structures of varying thickness. The result is an insert that maintains a flush profile with both opposing face sheets of the sandwich-type structure, thus reducing discontinuities in surface profile of the overall assembly.

1. An insert for use in a sandwich-type structure, the sandwich-type structure including face sheets attached to a core, the insert comprising:
a plug comprising:
an outer flange;a central portion having a wall extending from the outer flange, the wall defining an exterior surface; andan aperture extending through the outer flange and the central portion; and a sleeve configured for sliding engagement with the plug, the sleeve comprising:
an outer flange;a central portion defining an extension having a plurality of resilient beams; andan aperture extending through the outer flange and the central portion, the aperture of the sleeve being in communication with the aperture of the plug in an axial direction, wherein when the sleeve is slid into engagement with the plug within the sandwich-type structure, the plurality of resilient beams are elastically deflected by the exterior surface of the wall of the plug such that the insert can be positioned properly in the axial direction to accommodate sandwich-type structures of varying thickness.
