Standard umbilicals using screw-on lanyard, quick-release connectors often have to be replaced because they’re stiff, hard to handle and don’t survive pylon installation or operation. Replacing them is expensive, time-consuming and can delay critical missions. Heeding the call from military customers, W. L. Gore & Associates offers GORE MILD-STD-1760 Assemblies as the only affordable, sealed hybrid solution with a reliable connector system proven over time to solve these common pitfalls.
PROVEN SAFE OPERATIONS WITH HIGH FLEX LIFE
Successful missions depend on aircraft platforms that use reliable, long-lasting MIL-STD-1760 umbilicals. But, our customers have told us that they often have to replace standard umbilicals using screw-on lanyard, quick-release connectors. Why? Because they’re stiff, hard to handle and don’t withstand pylon installation or operation. Maintenance is time-consuming and costly because it involves removing many aircraft components to replace the damaged umbilicals with new ones.
Gore offers the only sealed hybrid solution proven over time to solve all of these problems. An affordable, easy-to-install umbilical with a connector system that doesn’t fail when installed or during operation.
CONSISTENT DISCONNECT LOADS
GORE MIL-STD-1760 Assemblies with the L3Harris™ Field Replacement Connector System (FRCS) are the only solution proven to guarantee safe operations with a low bend force over wide temperatures. They’re also proven to protect against electromagnetic interference (EMI) with at least 85% optical coverage. Not only that, our assemblies have a life beyond 100,000 flexes in harsh aerospace conditions without ever failing to do their job.
We thoroughly test and qualify our assemblies according to stringent military specifications. They’re certified for more than 100 ejected releases and 400 manual disconnects. For more than 25 years, our assemblies have delivered 100% successful store releases on many defense airborne platforms.
EASY PYLON INSTALLATION
Robust and highly flexible, our assemblies can be easily installed in limited spaces of aircraft pylons. They’re available in a variety of wire types by protocol with a smaller cross-sectional diameter compared to standard umbilicals. They can be easily attached and removed from ASI (Aircraft Store Interface) and MSI (Mission Store Interface) while operating in an NBC (Nuclear Biological Chemical) environment. Our assemblies reduce maintenance, downtime and product lifecycle costs because they don’t have to be replaced after each use.
GUARANTEED 100 STORE RELEASES
We worked with L3Harris to compare the performance of our assemblies with their FRCS against standard umbilicals that use screw-on MIL-STD-38999/31 lanyard connectors. We configured a simulator on stores with racks adjusted to represent various pylon stations accurately, including retention methods. Then, we captured the data to validate connector loads and store velocity during ejected pit releases.
Our results showed that 1 out of 10 new standard umbilicals separated within the specification limit after 100 drops. Also, 50% of the umbilicals were unserviceable after only 3 drops, and 25% failed to disconnect at all and ended up in the pit. But, GORE MIL-STD-1760 Assemblies with the connector system delivered consistent disconnect loads and can guarantee 100 fully high-speed instrumental drops.
