Energetic sub-systems of the highest quality and reliability, for a range of mission critical systemsCADs and PADsChemring designs and manufactures Cartridge Actuated Devices (CADs) and PropellantActuated Devices (PADs) used for a variety of functions including crew egress andweapon sub-systems. These products can also be used to start turbines and engines,as part of explosive ordnance disposal systems or for decoy dispersion and missilegyroscope energisation. Actions can be summarised as follows:• Puncturing containers(e.g. to release high pressure gas)• Pushing mechanical loads (e.g. opening valves)• Locking a device to prevent rotary or linear motion• Releasing a device to enable rotary or linear motion• Operating a sprinkler bulb• Operating a switch or delay• Cutting wires or small boltsPin Pullers and Pin PushersAlso known as protractors and retractors, our Pin Pullers and PinPushers are controlled-release mechanisms used in applicationsrequiring instant detachment of structural fittings, mechanisms,rods, cables, booms or parachutes. After functioning as structuraldevices and carrying full tensile or shear loads, these productsrelease upon command by an attached Chemring initiator. Fullretraction or protraction of the pin is achieved by pressurized gasdriving against the piston pin.ActuatorsActuators are highly reliable, compact single shot devices whichcan push, pull, cut or shear with a power-to-weight ratio in excess of10,000:1. They operate within milliseconds of receiving the appropriateelectrical impulse, a rate which is almost impossible to achieve witha mechanical source of energy. Actuators are ideal for remotecontrolled applications.Ejection Release UnitsCartridge Ejection Release Units (CERUs) provide gas pressure tooperate Aircraft Ejector Release Units (EJUs), for stores ejection oncombat aircraft.Gas GeneratorsGas Generators are self-contained units that can either be electricallyor percussion operated. Typical operating times vary between 25milliseconds to 250 seconds with operating temperatures in the range of-32°C to + 60°C. Specialised propellants can be incorporated to extendthe temperature range from -54°C to +150°C. Typical applications include:• Fluid Displacement• Liquid Fuel Igniters• Pressurisation of hydraulic power supplies• Ejection Release Units• Buoyancy Devices• Inflation of flame retardant fabric structuresOther CAD / PADs• Igniters and Fuseheads• Detonators• Cutters• Explosive Bolts• Release / Low Shock Bolts• Separation Nuts• Detent Actuators‘Metron’ Actuators.Gas Generators.4 Energetic Sub-Systems Delivering global protection

Energetic sub-systems of the highest quality and reliability, for a range of mission critical systemsSpaceSeparation SystemsAs a trusted supplier of space qualified components, Chemring products are designed to operate underextreme conditions. Our Separation Systems can reliably undertake a range of mission critical functions, withguaranteed levels of performance and reliability. Such functions might include the release of structures orcomponents such as multi-stage launch vehicles, separation of nose cones and capsules, or the release ofbooster rockets, tanks and other jettison equipment.Pyrotechnic Separation NutsGeneral features include lightweight, high-load capability, extremely lowshock output with complete gas and particle containment. These nutsactuate on very low pressure with large bolt insertion tolerance.Chemring also supplies ultra-low shock separation nuts, using asimilar design.Non-Pyrotechnic Separation NutsWe have developed an extreme low-shock output, non-explosiveseparation nut. These nuts are actuated by a miniature electric motoron low energy with large bolt insertion tolerance. Unique featuresinclude 25 times resettable and reusability and no need for disassembly.Separation BoltsOur separation bolts are designed and manufactured for use inapplications where rapid structure separation is demanded. Chemring’sSeparation Bolts have been fully qualified for fairing separation on theATLAS and DELTA launch vehicles. Bolts do not fragment; rather, theyseparate into two parts, one of which is ejected from the structure.Cutters (Bolt, Rod and Cable)Chemring cutters are designed for robustness and can be used in spaceas well as in deep submergence applications, for cutting reefing lines,electrical cables, steel cables or aluminium, titanium and steel boltsor rods. Over the past 20 years, our cutters have demonstrated highreliability on countless earth-orbital missions. Chemring cutters are builtwith the option to be single blade or mechanically redundant.Sample range of Separation and Release Units.Non-Pyrotechnic Electric Separation Nuts.www.chemring.co.ukEnergetic Sub-Systems 7

Energetic sub-systems of the highest quality and reliability, for a range of mission critical systemsMissilesChemring supplies a wide range of components supporting a number of critical missile,bomb and torpedo programmes across an international military customer base.Launch and FlyChemring manufactures actuators, retention mechanisms, motors and weapon release cartridges to enable arange of ‘Launch and Fly’ activities. Typical cartridge operating times are from 0.01 seconds to 10 seconds withoperating temperatures from -32°C to +60°C, although specialised propellants can be incorporated to extend therange from -54°C to +150°C. Other valves and separation systems allow fluid/gas flow and enables sequencedlaunch and fly events.Firing CablesLow altitude firing cables that are 360° shielded for EMC/EMIprotection.Piston ActuatorsUsed to crush a fuze, in order to start an explosive train or to arma Safe and Arm device.Bridgewire InitiatorsLow voltage, dual hot bridgewire cartridges that initiate numerouscomponents on a platform, including ignition of a gas generator formissile launch.Separation NutsTo attach the aft of a missile to a shipping canister or capsule launchingsystem and to restrain it until initiation.Cable CuttersElectrically initiated cable cutters sever electrical cable bundles eitherprior to launching, or during flight.High-pressure Pneumatic CylindersThese are used to start a sequence of control surface deployments,such as opening an inlet door to a sustainer motor.Lug Retraction DevicesUpon actuation of a cartridge, a spring loaded spreading rod extends toretract lugs into the missile body to reduce its radar cross section.Wing and Tail Retention MechanismsUsed to retain missile wings/tails during storage. Upon actuation, afrangible pin fails allowing missile wings/tails to rotate into a deployedorientation.Wedge Retention MechanismsDesigned to hold aerodynamic features in place during flight. Uponinitiation, features are allowed to release from the missile.The Joint Air to Surface Standoff Missile (JASSM) uses a rangeof flight components, including our wing retention mechanisms,shown above.The Tomahawk cruise missile uses a number of Chemringcomponents within its launch sequence.8 Energetic Sub-Systems Delivering global protection

Energetic sub-systems of the highest quality and reliability, for a range of mission critical systemsMissilesPyromechanical ValvesChemring supplies a number of pyromechanical valves, designed to be lightweight and reliable, which arecritical to the liquid and gaseous fluid systems for complex missile programmes. Valves can be either designedin a ‘normally open’ or ‘normally closed’ configuration, which ensures that valve combustion gases are fullycontained. Valves are typically associated with fuel flow and are initially designed to isolate fuel during storage,by sealing it within the fuel tank. Upon actuation, these valves allow unrestricted fuel flow to the missile and inparallel, unrestricted flow of pressurized air back into the fuel tank. Our valves are also employed in missile Divertand Attitude Control (DAC) systems.Safe & Arm Units (SAUs) and Flight TerminationOur electro-mechanical safe arm devices provide dual explosive output for remote safing/arming andsubsequent initiation of ordnance items. Our fully qualified products are suitable for system use and target droneapplications. Chemring designed, developed and qualified the SAD-505 for the US Air Force F-4 target drone.Qualified to MIL-STD-1516, this device provides remote arm and dual initiation for ordnance products. It featuresremote indication status and remote or manual safing.Chemring supplies a range of valves to critical missile programmes, including the THAAD (Terminal High Altitude Area Defense) programme.Chemring supplies a range of Safe and Arm units, including electronic Safe and Arm fuzes for the PAC-3 (Patriot Advanced Capability) programme.www.chemring.co.ukEnergetic Sub-Systems 9
