Flexible Confined Detonating Cord Assembly - Ensign

Flexible Confined Detonating Cord Assembly (FCDCA)
PRODUCT TECHNICAL DATA SHEET
DESCRIPTION:
Flexible Confined Detonating Cord Assembly (FCDCA)
is a linear explosive component widely used in the aerospace
industry for detonating signal transfer. The device consists
of a linear explosive cord, wrapped in a flexible confinement
tube which has end tips that can be connected into manifolds
or other ordnance devices.
KEY FEATURES:
• Provides confinement of the ordnance event
and gaseous products • Insensitive to unintended ignition from mishandling
or ballistic damage
• Rugged, flexible and lightweight
APPLICATION:
PROPERTIES:
• Fully proven on Tactical Missiles,
• Hermetically sealed and tested to a wide
Strategic Missiles and Space Launch Vehicles
range of temperatures
• Ideal for systems that require a robust,
• Available in any length and with numerous
high-strength, flexible energy transfer line
end tip types and thread sizes
• Designed to withstand demanding aerospace • Lockwire provisions come standard
environmental conditions
• RCC 319 Range Compliant
• Ideal for installations with tight bend radii

Construction:
Explosive End Tips:
•Type I and Type III end tips containing HNS-1A.
MDF Cord Materials:
• The explosive cord consists of an aluminum sheath containing HNS-IIA explosive.
Overwrap and Braiding Materials:
• Tefzel® Thermoplastic Elastomer, Kevlar® and Stainless Steel.
Free Spinning Threaded Nuts:
• Enable the FCDCA to be fastened into a manifold or other device.
• Different diameters and thread sizes to prevent incorrect installation.
OPERATION:
A detonation is required to initiate the FCDCA, which enables a detonating signal
to be transmitted along the length of the Mild Detonating Fuse (MDF) cord where
it is output from the tip at the opposite end. Manifolds may be used as interfaces
to distribute the signal from one FCDCA to another. The FCDCA transmits a
detonating signal from an ordnance initiating device to an output device such as
a Destruct Charge, Linear Shaped Charge or Frangible Joint.
