GORE® Aerospace Cables and Materials Brochure - Military Applications

High Data Rate Cables

Whether you need high-performance cables, reliable signal transmission or aerospace materials to reduce maintenance and downtime, you can be confident that GORE® Aerospace Cables and Materials for Military Applications deliver long-lasting reliable performance.

All Resources For GORE® MIL-STD-1760 Assemblies

Overview

Long-lasting, dependable performance is essential for military applications that use MIL-STD-1760 assemblies to ensure the success of any flight operation. But, our customers have told us that they have to replace frequently standard umbilical assemblies that use screw-on MIL-DTL-38999/31 land yard connectors because they don’t withstand pylon installation and operation.

Guaranteed 100 Store Releases

Introduced to NATO in the mid-1990s, we identified a need to provide a reliable, easy-to-use umbilical assembly with a connector system that didn’t fail during installation or operation. GORE MIL-STD-1760 Assemblies combined with the Harris Field Replaceable Connector System (FRCS) are successfully qualified against specification with proven, consistent disconnect loads. Certified for more than 100 ejected releases, our assembly with the FRCS has delivered more than 3,500 successful store releases on many airborne platforms such as:

  • A-10 Warthog
  • B-1B
  • F-15e, F-16 and F-35
  • Super Lynx
  • Tornado GR4
  • Typhoon

Easy Pylon Installation

GORE® MIL-STD-1760 Assemblies

Our MIL-STD-1760 assemblies can withstand repeated flexing without mechanical or electrical failure and have a proven flex life of more than 100,000 flexes for easy routing in limited spaces of aircraft pylons. With a robust, yet flexible construction, they reduce downtime and life-cycle costs because they don’t have to be replaced after each use.

Also, our assemblies can be attached to and removed from ASI (Aircraft Store Interface) and MSI (Mission Store Interface) while operating in an NBC (Nuclear Biological Chemical) environment in accordance with MIL-STD-1472, Paragraph 4.10. The technology enables fast and easy connector system replacement while maintaining proven product performance.

Features & Benefits

GORE MIL-STD 1760 Assemblies combined with the Harris Field Replaceable Connector System (FRCS) provide features that make them an ideal replacement for standard umbilical assemblies and connectors.

  • average release load of 550 + 85N (125 + 20 lb/f)
  • maximum release load of 880N (200 lb/f)
  • fail-safe operation up to 45˚ pull-off angle
  • consistent operation up to 75 mm of lanyard slack
  • all above tested during ejected pit releases up to 5 m/s
  • operational temperature range of -60˚ C to 150˚ C
  • Certified for 500 manual disconnects

GORE MIL-STD 1760 Assemblies provide manufacturers with many benefits that improve electrical and mechanical performance such as:

  • Harris FRCS with jam-free, push-on/pull-off connection that has been tested and guaranteed 100 ejected releases
  • superior electrical and mechanical performance in extreme environments
  • proven flex life more than 100,000 flexes for improved pylon installation and easy routing
  • robust construction for reduced life-cycle costs because they don’t have to be replaced after each use
  • a variety of connector options including standard shell size 25 and 17 store disconnects
  • a variety of standard cable assembly Class I and II offerings, or customized versions to meet any aircraft integration requirements
  • fully qualified, tested and flight-proven on many airborne platforms for reduced downtime, increased aircraft availability and lasting performance

Testing

Installed GORE MIL-STD-1760 Assembly

Gore and Harris performed validation testing on GORE MIL-STD-1760 Assemblies with the Harris Field Replaceable Connector System (FRCS) compared to standard umbilical assemblies that use screw-on MIL-DTL-38999/31 land yard connectors. We configured the test on stores with racks that were adjusted to represent accurately various pylon stations, including retention methods. Then, we captured the data during the test to validate connector loads and store velocity.

Our results showed that 1 out of 10 new standard umbilical assemblies with screw-on connectors separated within the specification load. But, GORE MIL-STD-1760 Assemblies with the Harris FRCS delivered consistent disconnect loads and can guarantee 100 fully instrumental drops.
