Embodiment Construction

[0081] According to the present disclosure, a method for rebuilding a structure comprising rebuilding core panels, a rebuilding structure comprising said rebuilding core panels, and a method for rebuilding a core panel in a rebuilding structure are disclosed. Guidance and equipment for honeycomb core panels. Other aspects relate to reconditioned acoustic panels and structures comprising honeycomb core panels, wherein the panels comprise reconditioned honeycomb core segments including but not limited to in acoustic panels and structures comprising the acoustic panels honeycomb core section. Aspects of the present disclosure further include contemplating reconditioned non-acoustic honeycomb core panels, and such panels reconditioned according to the methods disclosed herein and structures comprising reconditioned non-acoustic panels.

[0082] Acoustic panels include structures that are specially designed to absorb, control, or reflect sound from a specific area. For example, a...

Abstract

The present invention relates to structural reconstruction of honeycomb core panels. Methods for rebuilding structures and rebuilding honeycomb core panels, rebuilding structures including rebuilding honeycomb core panels, and guides and cutting apparatus for rebuilding honeycomb acoustic panels and rebuilding honeycomb non-acoustic panels are disclosed.

Description

technical field [0001] The present disclosure generally relates to structures for noise reduction and structures including such regions. More specifically, the present disclosure relates to the reconditioning of acoustic and non-acoustic panels for structures, methods of restoring the acoustic performance of such structures, and structures including reconditioned areas. Background technique [0002] Aircraft engine assemblies generate high noise levels due to high velocity airflow through inlets, rotating tables, exhaust nozzles, etc. To reduce this noise level and comply with noise regulations governing commercial aircraft, high-bypass type aircraft engine assemblies incorporate acoustic panels in various locations on the engine, such as in the nacelle inlet, thrust reverser, and the like. These acoustic panels (sometimes referred to as acoustic treatments) may include a baffled cellular or "honeycomb" core material oriented or "sandwiched" between a perforated inner skin ...
