Energetic Sub-Systems sector brochure - Chemring Group PLC

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
