Time Delay Devices Aircraft, Missiles, Space  

Pyrotechnic time delays offer the level of reliability required for crew escape systems in today’s fighter and transport aircraft, as well as stage separation in launch vehicle systems. These time delays provide sequencing and simultaneity of events with minimal input power making them ideal for egress, stage, payload, or fairing separation systems. CED manufactures qualified products with time delays ranging from 0.25 to 4+ seconds.

These devices offer the flexibility of multiple initiation methods and multiple outlet media. Input can be provided by Electro-Explosive Devices (EEDs) such as Standard 1A/1W initiators, Semiconductor Bridge (SCB), Laser Initiators, Exploding Bridgewire (EBW), and Through-Bulkhead Initiators (TBI). It can also be provided by a standard primer using a firing pin which can be used in a lanyard pull device in a parachute ripcord or stage separation system.

Linear products can also provide the impetus to initiate the pyrotechnic time delay with pressure output or detonation output. Output is provided to the next-in-line device or system as gas pressure or a detonation that functions a device such as a cable cutter, separation nut or valve. It can also provide output to a linear product such as FLSC, FCDC, or CDF in order to transfer output from one location to another or to multiple locations.

CED time delays are in use worldwide in aircraft such as the T-38, F-5, F-16, F-15, F-18, B-1, B-2, and C-17 as well as the Atlas V and Delta IV launch vehicles. CED can design the time delay for your specific requirement such as Crew Egress, Stage Separation, Sequencing, Engine Start, Safe Separation, and Multipoint Initiation.

Pyrotechnic and Pneumatic Actuators Aircraft, Missiles, Space  

CED Pyrotechnic and Pneumatic Actuators produce linear motion quickly, accurately, and reliably. Whether it is a pushing, pulling, or rotating motion, CED has supplied actuators for the most complex systems to include Fin/Wing Deployment, inlet door opening, spoiler retracting, arming/safing, canopy removal, stage separation, stores release/eject, payload release, parachute release, hatch/door removal, faring removal, or silo door opening. CED has designed, developed and produced numerous linear actuators. These actuators are functioned by pneumatic, hydraulic, or gas input sources.

The ability to design and analyze the configuration and to model the performance of the linear actuation system is an expertise of CED unmatched in this industry. CED engineers use CED’s proprietary SIBAC software to simulate propellant combustion and predict system dynamic response. A design can be modeled and reconfigured in a simulation, evolving in a design that that meets customer requirements when first developed.

Pyrotechnic Cutters, Separation Nuts and Bolts Aircraft, Missiles, Space  

CED has significant expertise in the design, development, testing and production of Separation Nuts and Bolts, and Pyrotechnic Cutters. These devices are used for “hold-and-release” or severing mechanisms. This expertise requires an in-depth understanding of dynamics and propellant combustion, as well as the material deformation/fracture and detonation mechanics.

CED’s pyrotechnic cutters have been manufactured for various commercial and military applications, including missile separation, crew egress, payload deployment and flight termination. CED designs and develops low shock, highly reliable separation nuts and bolts for applications in launch vehicle, satellite, and payload systems. CED separation nuts and bolts are used today in systems for attach and release of payloads, and stores and booster motors. CED separation nuts vary in size from ¼ inch to 1 ½ inch bolt sizes. Input for a separation nut can be provided by initiators, gas output from a transfer lines, or pneumatic pressure.

CED also manufactures Bolt Catchers and Retractors used in conjunction with Separation Nuts. These items are designed to retain (extract) a tension bolt after separation.

These are specifically designed for use in conjunction with Separation Nuts as standard hardware for separation systems. The bolt catchers and improved bolt retractors are designed to retain (extract) a tension bolt after separation. They prevent potential structural damage or component malfunction due to bolt ejection.

Thrusters Aircraft, Missiles, Space  

Thrusters push apart structural elements or to eject fastened components. Many types of vehicles have long used our thrusters. As with our pyrotechnic devices, thrusters are designed to withstand the severe environments of aerospace use.

Prior to actuation, the thruster serves as a mechanical fastener. It is actuated by a command signal delivered to a power cartridge or explosive end-tip. The gas energy is instantly released into a simple, highly reliable piston assembly which slides outward to apply a useable separation force.

Applications include:

  • Eject, jettison or separate structures
  • Pilot ejection capsules
  • Remove missile launch covers or radar lens protectors
  • Eject instrument packages and parachute canisters from re-entry vehicles
Pin Pullers and Pin Pushers Aircraft, Missiles, Space  

Our Pin Pullers 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, Pin Pullers release upon command by one of our initiators. Full retraction of the pin is achieved by pressurized gas driving against the piston pin.

Pyro Valves Aircraft, Missiles, Space  

CED manufactures Normally Closed Valves, Normally Opened Valves, and Sequencing/Selecting Valves, which are used in major military aircraft platforms, missile systems, and launch vehicles. Valves are functioned with Stored Gas Pressure, Electro Explosive Devices (EED) or by lanyard Pull/primer Initiation (LPI). Pyrotechnic valves are ideal for minimal power systems requiring absolute sealing or opening of a flow path and simultaneous function or sequencing of multiple events. Two distinct types of valves are provided; a media control valve and selecting valve.

CED’s media control valves function with liquid or gas media for cryogenic systems, stage separation systems, wing or fin actuation, and cover removal systems. Media control valves provide opening or closing of valves in a variety of sizes. CED provides large and small valves for use in aircraft, missile, launch vehicle and space applications.

CED provides selecting or sequencing valves offering manual selection of egress events and logical pyrotechnic selection of egress, separation and arming events. Pyrotechnic valves provide an extremely fast, extremely reliable method of opening or closing a flow path with small amount of power or lanyard pull input.
