Q

Function of Signal Distress Day/Night Smoke and Flare

A

Three layers of flare comp (red) housed in
aluminium liner.
Percussion igniter assy (primer, cambric / celluloid
strip) – extends centrally through filling:
Igniter striker held in safe position by “safety fork” which
engages a groove in outer end of the striker.
A “D” ring is secured through a swivel link to the safety
fork.
D Ring and swivel located immediately beneath the end
cap.
Pull and twist D ring:
This action allows the safety fork to release the striker
from the safe detent which strikes the percussion cap.
Produces flash that ignites the primed cambric and
celluloid strip running centrally through the main filling.
Burning cambric / celluloid strip ignites flare or smoke
composition dependant on which end is activated.

Q

SDDN No1 Mk5 description

A

Flare/(Smoke) Unit. The flare/(smoke) unit consists of three layers of flare composition (a smoke composition) housed in an aluminium liner. A percussion igniter extends through a central hole in the unit. The igniter’s striker is held in a safe position by a safety fork which engages a groove in the outer end of the striker; a D ring is secured through a swivel link to the safety fork. The D ring and swivel link are located immediately beneath the threaded end cap.
