Abstract
Systems and methods are provided for an aircraft propulsor thrust reverser with a fastening system. The fastening system may include a male spool and a female spool configured to be threaded into the male spool. The male spool and the female spool may be coupled to a honeycomb structure and may evenly distribute force to the honeycomb structure to prevent plastic deformation of a honeycomb core of the honeycomb structure.
Claims20
An aircraft propulsor comprising:
- a core engine;
- and
- a thrust reverser comprising an inner wall located proximate the core engine, the inner wall comprising:
- a honeycomb structure comprising a first facesheet, a second facesheet, a honeycomb core disposed between the first facesheet and the second facesheet, and an aperture, and
- a fastening system disposed within the aperture, the fastening system comprising:
- a male spool comprising a male spool body, wherein:
- an external threaded portion is disposed on at least a first end of the male spool body,
- a male through hole is disposed within the male spool body, and
- a male flange portion is disposed on a second end of the male spool body, is coupled to the first facesheet, and is configured to distribute load to the honeycomb structure;
- and
- a female spool comprising a female spool body, wherein:
- an internal threaded portion is disposed on at least a first end of the female spool body and coupled to the external threaded portion to fasten the male spool and the female spool to the honeycomb structure,
- a female through hole is disposed within the female spool body, and
- a female flange portion is disposed on a second end of the female spool body, is coupled to the second facesheet, and is configured to distribute load to the honeycomb structure.

A fastening system for a structure, the fastening system comprising:
- a male spool comprising a male spool body, wherein:
- an external threaded portion is disposed on at least a first end of the male spool body,
- a male through hole is disposed within the male spool body, and
- a male flange portion is disposed on a second end of the male spool body and is configured to couple to a first facesheet of a honeycomb structure and distribute load to the honeycomb structure when the male flange portion is coupled to the first facesheet;
- and
- a female spool comprising a female spool body, wherein:
- an internal threaded portion is disposed on at least a first end of the female spool body and is configured to couple to the external threaded portion to fasten the male spool and the female spool to the honeycomb structure,
- a female through hole is disposed within the female spool body, and
- a female flange portion is disposed on a second end of the female spool body and is configured to couple to a second facesheet of the honeycomb structure and distribute load to the honeycomb structure when the female flange portion is coupled to the second facesheet.
