Chemring designs and manufactures Cartridge Actuated Devices (CADs) and Propellant Actuated Devices (PADs) used for a variety of functions including crew egress and weapon systems. These products can also be used for a large variety of military and commercial functions ranging from crew egress and weapon systems to the activation of fire suppression systems in buildings and vehicles. 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 bolts

Pin Pullers and Pin PushersAlso known as protractors and retractors, our Pin Pullers and Pin Pushers are controlled-release mechanisms used in applications requiring instant detachment of structural fittings, mechanisms, rods, cables, booms or parachutes. After functioning as structural devices and carrying full tensile or shear loads, these products release upon command by an attached Chemring initiator. Full retraction or protraction of the pin is achieved by pressurized gas driving against the piston pin.

METRON ActuatorsActuators are highly reliable, compact single shot devices which can push, pull, cut or shear with a power-to-weight ratio in excess of 10,000:1. They operate within milliseconds of receiving the appropriate electrical impulse, a rate which is almost impossible to achieve with a mechanical source of energy. Actuators are ideal for remote controlled applications.

Ejection Release UnitsCartridge Ejection Release Units (CERUs) provide gas pressure to operate Aircraft Ejector Release Units (EJUs), for stores ejection on combat aircraft.

Gas Generators

Gas Generators are self-contained units that can either be electrically or percussion operated. Typical operating times vary between 25 milliseconds to 250 seconds with operating temperatures in the range of -32°C to + 60°C. Specialised propellants can be incorporated to extend the 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 structures

Other CAD / PADs• Igniters and Fuseheads• Detonators• Cutters• Explosive Bolts• Release / Low Shock Bolts• Separation Nuts• Detent Actuators

Pyrotechnic Separation NutsGeneral features include lightweight, high-load capability, extremely low shock output with complete gas and particle containment. These nuts actuate on very low pressure with large bolt insertion tolerance.Chemring also supplies ultra-low shock separation nuts, using a similar design.

Non-Pyrotechnic Separation NutsWe have developed an extreme low-shock output, non-explosive separation nut. These nuts are actuated by a miniature electric motor on low energy with large bolt insertion tolerance. Unique features include 25 times resettable and reusability, and eliminates the need for disassembly.

Separation Bolts Our separation bolts are designed and manufactured for use in applications where rapid structure separation is demanded. Chemring’s Separation Bolts have been fully qualified for fairing separation on the ATLAS and DELTA launch vehicles. Bolts do not fragment; rather, they separate 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 space as well as in deep submergence applications, for cutting reefing lines, electrical cables, steel cables or aluminium, titanium and steel bolts or rods. Over the past 20 years, our cutters have demonstrated high reliability on countless earth-orbital missions. Chemring cutters are built with the option to be single blade or mechanically redundant.

Missiles


Pyromechanical ValvesChemring supplies a number of pyromechanical valves, designed to be lightweight and reliable, which are critical to the liquid and gaseous fluid systems for complex missile programmes. Valves can be either designed in a ‘normally open’ or ‘normally closed’ configuration, which ensures that valve combustion gases are fully contained. 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 in parallel, unrestricted flow of pressurized air back into the fuel tank. Our valves are also employed in missile Divert and Attitude Control (DAC) systems.

Safe & Arm Units (SAUs) and Flight Termination Our electro-mechanical safe arm devices provide dual explosive output for remote safing/arming and subsequent initiation of ordnance items. Our fully qualified products are suitable for system use and target drone applications. Chemring designed, developed and qualified the SAD-505 for the US Air Force F-4 target drone.
