How Flexible Detonating Cord Works

Flexible Detonating Cord (FDC) is a type explosive transfer line consisting of metal-sheathed energetic material drawn in a round configuration with booster shell end tips.

Typical FDC is manufactured using Mild Detonating Cord (MDC) with minimal outer covering. An outer sheathing of flame retardant semi-rigid tubing produces a durable and flexible energy transfer line that permits easy routing in confined spaces. Its inherent reliability can be enhanced in system applications through the use of crossovers of the same energy transfer lines. High energy output tips are available with various explosive loads tailored to application requirements. End tip configurations can be provided to replicate Shielded Mild Detonating Cord (SMDC) Assemblies.

PacSci EMC FDC’s provide point to point detonation signal transfer allowing for the networking of explosive / pyrotechnic components. The loaded booster end tips are used for reliable detonation input and output. The detonation output can transfer to other FDC’s, to drive mechanical components (pin pullers, cable cutters, etc.) or to initiate larger explosive charges. FDC’s are best suited to application where containment of combustion by-products is not required and flexibility in routing during installation is desired. FDC is primarily used in missile, munitions and target vehicle Flight Termination System (FTS) applications, where byproducts of combustion containment is not required

PacSci EMC FDC’s are range safety approved for programs such as Standard Missile, Rocket Systems Launch Platform (RSLP), Payload Launch Vehicle (PLV), Supersonic Sea Skimming Target (SSST) and Minotaur IV.
