We have embraced our global leadership role to progressively replace our lead-sheathed linear explosives with environmentally conscious materials. We’re dedicated to sustainability business practices while still providing the most effective linear explosives to withstand high temperatures and provide the high performance that thousands of customers have come to rely on.
Our linear explosives – an explosive powder/material loaded into a tube that’s formed into long lengths – are manufactured in multiple sheaths including lead, tin, copper, silver and aluminum. We possess the ability to load high explosives (such as HNS, PBXN-5, HMX, and PETN) and deflagration materials (rapid deflagration material, time delay mixes, auto-ignition powders and more) to support a variety of linear parts and assemblies.
PacSci EMC’s linear products are available for a number of aerospace, defense and commercial solutions. Some of those include but not limited to:
- Emergency Egress (EES)
- Canopy Fracturing or Canopy Fracturing Initiation (CFS/CFIS)
- Transparency Removal (TRS)
- Missile/Drone/UAV Flight Termination/Destruct (FTS)
- Payload Deployment or Placement
- Stage Separation Events
- Thrust Termination
- Skin Severance
- Thermally Activated Safety Systems (TASS)
- Engine Start Event Sequencing
- Oil & Gas Industry Applications
PacSci EMC produces three types of MDC loaded detonating ETLs. Each has an end fitting with loaded boosters and threaded fittings for installation in to other components. The ETLs we produce and their unique features are:
Ridged lines, bent to customer required configurations and designed for rugged environments (high traffic, heat, etc.). These lines are hermetically sealed within a stainless steel tube and end fittings and when functioned, contain all byproducts of combustion. Information to come for High Pressure SMDC Details/Envelope
Confined Detonating Cord (CDC): Flexible lines designed with layers such as polyethylene, fiberglass, Kevlar and stainless steel braiding to ensure confinement of detonating byproducts when functioned. Information to come for High Pressure SMDC Details/Envelope
designed as a cost effective and robust ETL for primary use in missile, munitions and target vehicle Flight Termination System (FTS) applications where byproducts of combustion containment is not a requirement
(RDCTLs) are semi-rigid lines loaded with RDC inside an aluminum or stainless steel tube. They have the flexibility to route in modern aerospace and defense structures and the strength to withhold their shape and provide damage tolerance and reliability. RDCTL’s smaller diameter and lighter weight make them ideal when weight and volume are critical to a vehicle. RDCTL are designed with three types of end fittings to allow for various combinations of input stimulus and output requirements.
- High Energy (HE) generating or accepting a detonation event.
- Low Energy (LE) generating or accepting a pressure or flame front event. This line can’t initiate an HE end fitting.
Percussion Primer (PP) accepting a mechanical input from a firing pin striking this end fitting. RDCTLs with this end fitting allow the replacement of traditionally explosive loaded parts with inert devices (i.e. Inert Arm Fire Initiator, Inert Gas/ RDCTL Initiator, Inert Acceptor, etc.). The output from this line can be LE or HE.
PSEMC’s Expanding Tube Assembly (XTA) technology – also known as Expanding Shielded Mild Detonating Cord (XSMDC) for some aircraft applications – is a formed steel tube containing an MDC. Formed into an oval shape and sealed on both ends by loaded booster shells or manifolds, the tube can be used as a separating device for stage separation, unlock medium or canopy jettison and thrust mechanism to induce thrust between two structures. This proven design is reliable and lightweight and offers contamination-free assembly for multiple aerospace applications.
