The present disclosure related to a method for manufacturing a structure with cellular cores that can be used in a structural panel of a turbojet nacelle, including at least one block of cellular cores. The at least one block of cellular cores includes a central portion with core honeycomb cells, and two side portions each including side honeycomb cells. The side honeycomb cells have edge honeycomb cells situated on edges of a side part of a block, and adjacent honeycomb cells. In particular, the method includes: A) forming junction walls on the side honeycomb cells by opening the edge honeycomb cells, the junction walls being capable of interacting for forming a junction area; B) unfolding the junction walls thus formed in step A; and C) joining the junction walls thus unfolded in step B and belonging to two different side portions end-to-end.

Method for manufacturing a structure with cellular cores for a turbojet nacelle

The invention relates to a honeycomb core structure () for use in a structural panel for a jet engine nacelle, comprising at least one block with a honeycomb core (A, B) having a central part () with core honeycomb cells () and at least two lateral parts () each comprising a number of honeycomb joining cells () of which at least one part of the honeycomb joining cells () has at least one additional wall () to form a join, the honeycomb core block(s) (A, B) being connected by at least one joint zone () formed by punching two additional walls () superimposed one or the other and provided by honeycomb joining cells () belonging to the distinct lateral parts (). The invention further relates to a structural panel and a nacelle comprising such a structure () and a method for producing such a structure ().
