Noise reduction sandwich panel, notably for an aircraft turbojet engine. In order to produce a noise reduction sandwich panel having a structure with two degrees of freedom, inserted separative components (20) are placed into the hexagonal cells (16) of the unique waffle core of the panel. More specifically, the separative components (20) have an substantially circular external peripheral edge, which allows them to be easily assembled, in spite of the deformations of the walls (18) of the cells (16) due to manufacturing tolerances and to the optional forming of the waffle core. Advantageously, several separative components (20) are supported by a same positioning unit (22), which then allows relative displacement between the separative components.

A flexible core element having a large bonding surface area suitable for sandwich type construction comprising a plurality of first hexagonal nodes defining a first surface, a plurality of second hexagonal nodes defining a second surface spaced apart from and parallel to the first surface, and a plurality of rectangular wall members which interconnect said first hexagonal nodes to said second hexagonal nodes and define the depth of the core element. Each hexagonal node corresponds to an open hexagonal cell on its obverse surface and serves as a bonding surface. The core element is fabricated from a continuous sheet of material that has been die-cut with a repeating geometrical design, creased and folded, concertina style, in upon itself to make a double-sided core material that is flexible, able to vent, exhibits good bend and shear strength, and has a large surface bonding area rendering it suitable in the construction of lightweight sandwich panels and offering a wide array of other applications.

Spatial location systems can be based on multi-resolution grids such as mixed aperture combinations of hexagonal cells. A particular finest resolution can be selected based on a suitable combination of intermediate grid apertures such as arbitrary combinations of aperture 3, aperture 4, and aperture 7 hexagons. Location identifiers can be uniquely assigned by generating child cells from a parent cell so that the generated child cells do not overlap child cells of other parent cells. One or more child blocks can be used at any resolution to avoid such overlap. For aperture three and aperture four hexagonal cells, blocks of four and three child cells, respectively, can be used to provide unique location identifiers.

A honeycomb structure body is composed of hexagonal cells and an outer peripheral wall. Each hexagonal cell is surrounded by six cell walls of a hexagonal arrangement. The cell walls are divided into standard cell walls and reinforced cell walls. The strength of each reinforced cell wall is stronger than that of each standard cell wall. The reinforced cell walls form a strength reinforced area. Each component in the strength reinforced area has an approximate straight-line shape observed on a cross section in the diameter direction of the honeycomb structure body. Both ends of each component in the strength reinforced area are contacted to the outer peripheral wall.

A honeycomb structure has hexagonal cells surrounded by partition walls and a cylindrical outer peripheral wall covering the honeycomb structure. The partition walls have sides and intersection points. Six sides form a hexagonal cell. Three sides as the partition walls are joined to each other at a corresponding intersection point. The sides are divided into sides of basic partition walls and strength reinforcement sides as strength reinforcement partition walls. The strength reinforcement partition wall is thicker than the basic partition wall. Three strength reinforcement sides are joined at a corresponding strength reinforcement intersection point. Each strength reinforcement side in one group joined at one strength reinforcement intersection point is not connected continuously to each strength reinforcement side in another group joined at another strength reinforcement intersection point. The strength reinforcement intersection points are arranged on an entire surface of a radial cross section of the honeycomb structure.

A vapor display device includes a water tank [101], an expansion chamber [102] for creating vapor (which may contain scents), an airbox [104] for creating a laminar flow of air and vapor, and a projector [107] for projecting light onto the vapor display screen. The airbox has a series of mesh and honeycomb panels, preferably made of hexagonal cells having 3/16 inch width. Preferably, the vapor consists of water droplets having mean diameters in the range from 10 to 20 microns, and the laminar flow of air and vapor comprises between 1% and 5% water vapor. Potentiometers allow user control of vapor density, vapor flow speed, and airflow speed. A modular design allows the device to be used in different orientations.
