Monolayer or bi-layer acoustic absorption panel manufacturing method for engine i.e. jet engine, nacelle of aircraft, involves attaching core blocks in edge-to-edge manner and drying blocks, so that recesses are imbricated with each other

摘要

The method involves forming a honeycomb core by edge-to-edge assembly of a set of honeycomb core blocks (B1, B2). Pocket recesses (A1, A2) are opened before the edge-to-edge assembly of the set of honeycomb core blocks, where the pocket recesses are located on edges of the set of honeycomb core blocks to be attached. The set of honeycomb core blocks is attached in an edge-to-edge manner, and is dried so that the open pocket recesses are imbricated with each other. The imbrication of the open pocket recesses is maintained by fixation components such as couplers. An independent claim is also included for an element surrounded by an engine nacelle of an aircraft.
