Cord Cutter

EBAD is the global leader in ordnance and pyrotechnic devices for the launch vehicle, missile, and spacecraft markets. Pyrotechnic Cutters are devices for the severance of rods, tubes, cables, bolts or other hold downs. Actuation of the device is by electrical signal and it is rapid, reliable and effective.

Principle of Operation

The pressure cartridge, inside the device, is electrically initiated. Once initiated, the fully confined output produces enough gas pressure within the Cord Cutter to first break a shear pin, forcing the cutter blade down the shaft to impact on the target material, thus severing it. The shape of the blade has been optimized for a 900 pound Kevlar braided cord or a 800 pound Vectran braided cord. The blade comes to rest on an anvil. The actual time from the current application to full severance of the material will be less than 20 milliseconds.

The Cord Cutter has been specifically designed and qualified to function underwater to a depth of 5 feet. Its wide operational temperature range and high level of demonstrated reliability make it an ideal choice to sever a variety of cord applications.

Construction

EBAD’s Cord Cutter has a Stainless Steel housing that contains all the critical components. The design and construction allow for high pressure seal capability during and after actuation. The cutter is designed to prevent fragmentation or leakage of exploded gases externally or into the flow passages. The entire assembly is environmentally sealed. The Cord Cutter has a Stainless Steel blade designed to cut through a 900 pound Kevlar braided cord or a 800 pound Vectran braided cord.
