A method is provided for forming a structured panel. During this method, a cellular core is formed that comprises a corrugated ribbon configured with a plurality of baffles and a plurality of septums. Each of the septums extends longitudinally between and connected to a respective adjacent pair of the baffles. At least one element of the corrugated ribbon includes a structural reinforcement. The forming includes: feeding a ribbon of material between a first roller and a second roller, corrugating the ribbon of material with the first roller and the second roller to provide the baffles and the septums, and stamping the structural reinforcement into the element with the first roller and the second roller. The cellular core is bonded to a first skin. The cellular core is bonded to a second skin. The cellular core is vertically between the first skin and the second skin, and the first skin is configured with a plurality of perforations.

Forming a structured panel with one or more structural reinforcements

A structured panel is provided that includes a first skin with a plurality of perforations, a second skin and a core. The core forms a plurality of cavities vertically between the first skin and the second skin. Each of the cavities is respectively fluidly coupled with one or more of the perforations. The cavities include a first cavity. An element of the core is configured with a multi-layered structure. The multi-layered structure includes a first layer and a second layer attached to the first layer. The first layer is configured with a first rib projecting into the first cavity.

Structured panel with multi-panel structure(s)

An inner fixed structure (IFS) seal arrangement may comprise an IFS comprising an inner skin, and outer skin, and a cellular core located between the inner skin and the outer skin, an IFS seal, a seal retainer configured to retain the IFS seal, and a cooling flow channel disposed between the outer skin and the seal retainer.

Sealing cooling inner fixed structure

A panel is provided for attenuating sound. This panel includes a perforated first skin, a second skin and a core. The core forms a plurality of cavities vertically between the perforated first skin and the second skin. The core includes an array of corrugations that include a first baffle, a second baffle and a first septum. The cavities include a first cavity formed longitudinally between the first baffle and the second baffle. The first cavity is fluidly coupled with perforations in the first skin. The first septum extends from the first skin and the first baffle to the second skin and the second baffle. The first septum divides the first cavity into fluidly coupled sub-cavities. At least one element of the panel includes at least one first rib and at least one second rib, the first rib extends along a first trajectory and the second rib extends along a second trajectory that is non-parallel with the first trajectory.

Structured panel with structural reinforcement(s)

An electric heater () for integration into an acoustic panel () having sound-penetrating pores () communicating with a sound-canceling medium. The heater () includes an electrically conductive layer () with resistance-setting apertures () filled with sealant (). Openings (), which contribute to the sound-penetrating pores (), extend through the sealant-filled apertures (). The acoustic panel () can be assimilated into an aircraft component, such as a nacelle inlet lip, which requires both noise-reducing and ice-protecting features.

Electric heater for integration into an aircraft acoustic panel

An aircraft component includes a first segment having a first leading edge surface that extends to a first end of the first segment. The aircraft component also includes a second segment having a second leading edge surface that extends to a second end of the second segment. The second end is substantially adjacent to the first end of the first segment, and is connected to the first end. The first leading edge surface includes electrical resistance heating that extends to the first end of the first segment. In addition, the second leading edge surface includes electrical resistance heating that extends to the second end of the second segment. The electrical resistance heating is capable of providing ice protection heating immediately on either side of a juncture between the connected first and second ends.
