Explosive Bolts

Explosive Bolts are used for fastening mating components or devices together to then allow rapid structural separation when commanded. Also known as pyrotechnic fasteners, explosive bolts feature machined geometries to control the separation location and breaking strength. An explosive charge, located within a machined cavity in the bolt, or externally for Piston Bolts (Propulsive Bolts), provides the energetic stimulus required to cleanly separate the bolt at the predetermined break plane.

A pyro cutter uses energetic materials and a cutting blade to sever objects. It is a cartridge actuated device which, when initiated, will sever/cut 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.

The key factors for the cutter are the design of the cutter blade and the control of the cutting capacity to ensure that the bolts can be completely cut.

The design of a pyrotechnic cutter is an actuating component of a hold-down and release device, and it consists of an igniter, a casing, a detonator, a shear pin, a sealing ring, a cutter, a cutting board, and an end cover.

Description

Explosive bolts efficiently secure two objects and strategically explode, jettisoning those objects on command when commanded. These bolts initiate a perfect failure at the pivotal moment they need to. This part is designed for missile, launch vehicles, spacecraft and marine applications where rapid structure separation is demanded. Standard explosive bolts and ridge cut explosive bolts are available in a wide range of sizes, configurations and tensile capacities from as little as 200 pounds to as much as 1,000,000 pounds. As an explosive bolt manufacturer, our experts are here to support you in meeting your structural loading, envelope and environmental requirements and guide you on ways to mitigate shrapnel and products of combustion.
