PYROTECHNIC CUTTER

Pyrotechnic cutters are used to sever a multitude of materials and cross-sectional shapes. Common targets used with ordnance cutting devices include: steel, electrical or fiber optic cables, aluminum, titanium, copper, kevlar, vectran, zylon, bolts, tubes and woven fiber cords/lines and straps.

HOW OUR CUTTERS WORK

Pyro cutters can be mechanically, electrically or laser initiated. After initiation, energetics drive a blade to forcibly slice the target material. Energetic loading, blade geometry, anvil geometry, and structural materials are all variable based on target and application requirements. Time from input of firing energy to completely severing the target material is on the order of several milliseconds for most applications.

FUNCTIONS

Pyrotechnic cutters are used to sever steel, electrical or fiber optic cables, bolts, tubes and woven fiber cords/lines on a multitude of applications. Typical applications for pyro cutters are stage separation systems, staging parachute systems ( reefing lines ), opening electrical or fiber optic line circuits, releasing pre-loaded / folded assemblies ( i.e. wing, fin, etc.) and releasing cargo or munitions restrained by cords, flight termination systems (FTS) and balloon tethering.

APPLICATIONS

We have designed and manufactured 100’s of different cutters for 100’s of applications. Qualified and used in various military, commercial, and aerospace platforms including spacecraft, launch vehicles, aircraft (military and commercial), satellites and multiple missile platforms.
