Overview

The aerospace environment routinely exposes cables and materials to harsh conditions and contaminants such as fuels, oils, and chemicals that can degrade aircraft structures and cause cable failure in sensitive avionics.

Vapor-Sealed Assemblies for Lifetime Performance

GORE Microwave Sealed Airframe Assemblies prevent the ingress of water vapor, jet fuel, and other harsh contaminants. Our durable assemblies are qualified for civil and military airborne applications and meet stringent MIL-T-81490 mechanical and environmental requirements.

Also, our 7 Series maintain low insertion/return loss and phase performance over the entire life cycle. Not only that, they provide outstanding shielding effectiveness against electromagnetic interference that can compromise signal integrity over long distances and reduce the quality of signal transmission.

When it comes to installation, maintainers will find it much easier to route our assemblies in confined areas of an aircraft because they have a smaller cable diameter, increased flexibility, and a tighter bend radius. So, our assemblies won’t break or fail, like other standard airframe assemblies that are more rigid.

All of this means superior electrical and mechanical performance over the aircraft’s lifespan, reduced system downtime, and lower total costs for civil and military aircraft operators.

Gore’s 7 Series maintain low insertion/return loss and phase performance over the aicraft lifecycle.

Applications

GORE Microwave Sealed Airframe Assemblies, 7 Series are engineered to perform reliably in a variety of civil and military aerospace applications, including:

  • airframe interconnects for electronic defensive systems (signal detection, interception, identification)
  • commercial and business aircraft SATCOM connectivity
  • electronic payload interconnects including active electronically scanned array (AESA) radar

If you have any questions or to discuss your specific application needs, please contact a Gore representative.

Benefits

GORE Microwave Sealed Airframe Assemblies, 7 Series provide manufacturers with many benefits that improve electrical and mechanical performance such as:

  • durable vapor sealing prevents ingress of contaminants
  • flexible cable assemblies for ease of installation
  • easy routing in confined spaces due to small diameter
  • outstanding shielding effectiveness from durable cable construction
  • low insertion loss for a given diameter
  • maintains insertion loss, return loss and phase performance over entire life cycle
  • meets the mechanical and environmental requirements for airframe cables defined in MIL-T-81490
  • comprehensive qualification data available to support product claims

For more information about the benefits of our cables, please contact a Gore representative.
