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. Time Delay duration runs from very short times such as 1 millisecond up to several minutes.
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 system 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 Delta IV launch vehicle. CED can design the time delay for your specific requirement to include Crew Escape Events, Stage Separations, Sequencing, Engine Start, Safe Separation, and Multipoint Initiation.
