Title
(EN) SPLICING OF CURVED ACOUSTIC HONEYCOMB
(FR) RACCORDEMENT DE STRUCTURE ACOUSTIQUE EN NID D'ABEILLES INCURVÉE
Abstract
(EN)
Honeycomb sections are bonded together with seams made up of an adhesive that is carried by a honeycomb seam support or a linked-segment seam support. The seams are particularly useful for splicing together curved honeycomb sections that contain acoustic septum. The curved acoustic honeycomb sections are spliced or seamed together to form engine nacelles and other acoustic dampening structures.
(FR)
Des sections en nid d'abeilles sont liées ensemble par des jointures constituées d'un adhésif qui est supporté par un support de jointure en nid d'abeilles ou un support de jointure à segment lié. Les jointures sont particulièrement utiles pour le raccordement de sections en nid d'abeilles incurvées qui contiennent un septum acoustique. Les sections de structures acoustiques en nid d'abeilles incurvées sont raccordées ou jointes ensemble pour former des nacelles de moteurs et d'autres structures d'amortissement acoustique.
