A flow path duct system for a propulsion system of an aircraft includes a base defining a flow surface. The base has an internal surface and an external surface. A plurality of perforations are formed through the base between the internal surface and the external surface. A plurality of supports define a plurality of cavities. The plurality of supports extend outwardly from the external surface of the of the base. One or more of the plurality of cavities are in fluid communication with the one or more of the plurality of perforations. A backing surface is secured to the plurality of supports. The plurality of supports are disposed between the base and the backing surface. The one or more of the plurality of cavities are in fluid communication with an internal volume defined by the internal surface of the base through the one or more of the plurality of perforations. The base, the plurality of supports, and the backing surface can be integrally formed together as a monolithic, load-bearing structure.

Propulsion flow path duct systems and methods

Systems, methods, and apparatus for an electromagnetic (EM) panel are disclosed. In one or more embodiments, a disclosed electromagnetic (EM) panel comprises an outer skin, an inner skin, a core disposed between the outer skin and the inner skin, and at least one receiver to receive at least one first signal. In at least one embodiment, at least one receiver is disposed within an opening on the outer skin of the EM panel. At least one receiver is an optical sensor(s) and/or a radio frequency (RF) antenna(s). In one or more embodiments, the EM panel further comprises at least one transmitter to transmit at least one second signal. In at least one embodiment, at least one transmitter is disposed within an opening on the outer skin of the EM panel. At least one transmitter is a laser(s) and/or a RF antenna(s).

Conformal load bearing distributed sensing arrays

A composite member that includes plies of composite material and an integral antenna. The integral antenna includes one or more plies of conductive material. A pin is connected to and extends outward from one of the conductive plies. The pin extends through openings in one or more of the composite plies that are positioned between and/or around the one or more plies of conductive material.

Method to embed an antenna within a composite panel

A method for designing an antenna including defining an operating frequency of an antenna radiating element located within an antenna cavity structure; determining a non-loaded depth of the antenna cavity structure; determining a reduced depth of the antenna cavity structure; determining a reduction factor to reduce the non-loaded depth to the reduced depth; and selecting a dielectric material, at least partially forming a radome structure covering the antenna radiating element, to achieve the reduction factor.

Cavity antenna with radome

An antenna assembly includes a base including one or more feed transitions, a support panel separated from the base, a patch secured to the support panel, and one or more T-shaped probes that couple the feed transition(s) to the patch. The T-shaped probe(s) are separated from the patch.

Electronically scanning antenna assembly

Embodiments of the present disclosure provide an antenna assembly that includes a plurality of separate and distinct antenna modules that are interconnected together to form an antenna layer. Each of the antenna modules may include a support structure including a core frame connected to a core support, and a backskin connected to one or both of the core frame and the core support. The antenna assembly may also include an alignment grid configured to receive and align each of the antenna modules, and/or a matching layer configured to receive and align each of the antenna modules.

Modular antenna assembly

An antenna includes an antenna cavity structure that defines an antenna cavity and that has a cavity opening. The antenna also includes an antenna radiating element located within the cavity opening and operable to emit electromagnetic radiation that has a frequency and a wavelength and a radome structure covering the cavity opening. The radome structure includes a dielectric material and defines an antenna window that is transparent to the electromagnetic radiation. Due to the dielectric material of the radome structure, the antenna cavity has a depth less than one-fourth of the wavelength of the electromagnetic radiation and the cavity is filled with a low-dielectric material.

A broadband stacked multi-spiral antenna array comprising two or more spiral antennas with a dielectric layer having a generally uniform thickness positioned between each pair of stacked antennas, which are all center-fed and in-phase. The antenna array may be embedded in a non-conductive material, such as fiberglass embedded in a resin, a honeycomb core sandwich, or structural foam, that may be used to form a structural element of a mobile platform. The structural element may include a via providing a pathway for coaxial cables. If two structural elements are hatch covers on the port and the starboard sides of an aircraft, the use of a stacked multi-spiral antenna array in each structural element provides two roughly hemispherical coverage patterns which together provide an omni-directional coverage pattern. The stacked multi-spiral antenna array may also include a reflecting cavity placed at the bottom of one of the spiral antennas.
