aircraft parachute flares. The SUU-25F/A dispenser is
made up of four aluminum tubes housed in a supporting
frame and covered with aluminum skin. Each tube is
loaded with a pair of flares configured with a flare
adapter kit. The dispenser allows the flares to be ejected
one at a time, thereby doubling the mission capability
over previous models. Each tube has two flares. The
forward bulkhead (A) of the dispenser has breech
assemblies for eight impulse cartridges (one for each
flare). Four aft retaining links (B) attached to the rear
bulkhead keeps the aft flares in the dispenser tubes until
they are ejected.
When initiated by the pilot, the impulse cartridge in
the number 1 breech will be fired. The resulting gas
pressure is routed into the launcher tube. Gas pressure
buildup will be sufficient enough to force the flare aft
and shear the aft retaining lock shear pin, allowing a
single flare to be ejected from the launcher tube. A
stepper switch automatically steps the firing circuit in
the dispenser to the next tube. Each subsequent
activation of the firing circuit steps the stepper switch
and repeats the process for the remaining tubes.
AN/ALE-29A Countermeasures Chaff
dispensing set (chaff dispenser) (fig. 8-35) is an
electronic device installed in most Navy combat
aircraft. The chaff dispenser ejects cartridge-loaded
configurations of Mk 46 or MJU-8/B decoy flares and
RR-129 or RR-144 chaff.
Decoy flares are used during evasive maneuvers
against heat-seeking missiles. Chaff rounds consist of
extremely fine shredded metal strips in a cylindrical
metal container. When ejected, the metal strips cause a
installations or radar-controlled missiles.
GUIDED MISSILE LAUNCHERS
A guided missile launcher provides mechanical
and electrical means of suspending and air launching a
guided missile from an aircraft. The launcher either
ejects the missile or the missile leaves the launcher rails
under its own power. Each of these type launchers is
discussed briefly in the following text.
