A composite acoustic liner has a septumized cellular core. Septa are installed in the core as the individual core cells are being formed. Individual tools are used to both form the cells of the core and index the septa within the cells. The septa and the cellular core are cocured.

Septumization of cellular cores

A laser cuts overlapping ribbons of acoustic material into acoustic devices. An automatically controlled manipulator includes an end effector having groups of placement tools for simultaneously placing multiple acoustic devices in a cellular core. The placement tools include mandrels provided with vacuum pickups for picking up and holding the acoustic devices during transport to the core. A vision system aligns the placement tools with the cells of the core. The end effector includes a thermal radiation device for bonding the acoustic devices to the core.

Automated production of acoustic structures

A method and apparatus comprising a first composite layer and a second composite layer in which the second composite layer is associated with the first composite layer. The first composite layer and the second composite layer form a structure. The second composite layer has a conductivity configured to dissipate an electric charge on a surface of the structure and limit a flow of an electrical current in the second composite layer in which the electrical current is caused by an electromagnetic event.

Electric charge dissipation system for aircraft

An acoustic liner having a honeycomb core is fabricated by forming septa in a sheet of material, and assembling the sheet of material and the core. During the assembly process, the septa are respectively inserted as a group into cells of the core.

Septumization of honeycomb sandwiches

An induction welding system is provided. The system includes at least one induction coil configured to generate an alternating magnetic field, and a smart susceptor film sized to be positioned between a first component and a second component to be welded to the first component. The smart susceptor film includes a thermoplastic resin, and a plurality of metal alloy wires disposed in the thermoplastic resin such that the plurality of metal alloy wires are oriented substantially parallel to the generated alternating magnetic field.

Systems and methods for use in induction welding

A method, apparatus, and composite fuel tank for manufacturing a structure is provided. A first composite layer and a second composite layer are placed on a mold. The second composite layer and the first composite layer are cured. The first composite layer and the second composite layer form the structure. The second composite layer is configured to dissipate an electric charge on a surface of the structure.

A method and apparatus for attenuating sound. Air, through which acoustic waves are traveling, is received within a core comprised of a plurality of cells. The sound created by the acoustic waves is attenuated using a set of channels through a number of cell interfaces between cells of the plurality of cells by allowing the air to flow between the cells of the plurality of cells through the set of channels.

Sound attenuation using a cellular core

Honeycomb cores for use in aerospace applications include two honeycomb core sections operably joined at a splice joint, the splice joint defined by a foam adhesive that is sandwiched between a sheet of film adhesive. Methods of assembling honeycomb cores also are disclosed herein.

Honeycomb cores with splice joints and methods of assembling honeycomb cores

The disclosure provides a thermoelectric composite sandwich structure with an integrated honeycomb core and method for making. The thermoelectric composite sandwich structure comprises two prepreg composite face sheets and an integrated honeycomb core assembled between the face sheets. The honeycomb core comprises a plurality of core elements bonded together with a core adhesive. Each core element has a first side substantially coated with a negative Seebeck coefficient conductive material having a plurality of first spaced gaps, and each core element further has a second side substantially coated with a positive Seebeck coefficient conductive material having a plurality of second spaced gaps. The honeycomb core further comprises a plurality of electrical connections for connecting in series the first side to the second side. A temperature gradient across the honeycomb core generates power.
