Abstract

According to an aspect, a waveguide system includes a first node, a second node, and a double-ridge waveguide. The double-ridge waveguide includes a metallic shell surrounding a waveguide core that forms a communication and radio frequency power transmission path in an aerospace environment. The first node is configured to propagate at least one communication channel and a radio frequency power transmission through the waveguide core to the second node during operation of the waveguide system in the aerospace environment.

First claim

a first node;
a second node; and
a waveguide having first and second ridges, the waveguide comprising a metallic shell surrounding a waveguide core that forms a communication and radio frequency power transmission path in an aerospace environment, wherein the first node is configured to propagate at least one communication channel and a radio frequency power transmission through the waveguide core to the second node during operation of the waveguide system in the aerospace environment, wherein the metallic shell of the waveguide comprises a plurality of ribbed supports distributed along an axis of transmission between a first transmission volume and a second transmission volume of the waveguide core.

2. The waveguide system of claim 1 , further comprising a plurality of nodes connected by two or more instances of the waveguide.

3. The waveguide system of claim 1 , wherein the waveguide core is sized to propagate the at least one communication channel, and the radio frequency power transmission at a frequency range between 4 Gigahertz and 8 Gigahertz.

4. The waveguide system of claim 1 , wherein a metallization thickness of the metallic shell is equal to or greater than a skin depth to confine electromagnetic radiation within a structure formed by the waveguide.

5. The waveguide system of claim 1 , wherein the waveguide core comprises a polymer material through which the at least one communication channel and the radio frequency power transmission are propagated.

6. The waveguide system of claim 5 , further comprising a polymer intensifier having a different dielectric property than the polymer material, wherein the polymer intensifier is formed between a first transmission volume and a second transmission volume of the waveguide core.

7. A system for a gas turbine engine, the system comprising:
a first node of the gas turbine engine;
a second node of the gas turbine engine, wherein the second node is configured to interface with at least one sensor or at least one actuator of the gas turbine engine; and
a double-ridge waveguide comprising a metallic shell surrounding a waveguide core that forms a communication and radio frequency power transmission path, wherein the first node is configured to propagate at least one communication channel and a radio frequency power transmission through the waveguide core to the second node during operation of the gas turbine engine, wherein the waveguide core within the metallic shell of the double-ridge waveguide comprises a polymer material through which the at least one communication channel and the radio frequency power transmission are propagated.
