Benefits of pyrotechnics
- The functioning time of such equipment is extremely short
- While and even after functioning the equipment retains all gas generated by the pyrotechnic components and has no external outgassing
- Our cutters are designed to cut up to several millimeters of different kinds of metallic or composite hardware (steel, copper, etc.), in rods or in cables, those cables possibly combining different layers of different material (Kevlar, plastic, optical fiber, etc.)
Defence applications
- Flight Termination Systems of different families of missiles : the function of the cutter is then to cut the cables actuating the steering rudders of the missile
- Wing deployment actuation on a cruise missile : the function of the cutter is to cut a rod which then releases the mechanism which enables the wing deployment
- Emergency release of helicopter winches : in case of emergency the function of the cutter is then to release the payload pulled by a winch (for instance a sonar)
