Question 10

In regards to the flare countermeasure infra-red DSTL 22 what is it’s burn and delay times

Burn time - 5 sec max
Pulse duration - 10ms
Ejection velocity - 35 to 55 m/sec

Question 11

Why do they have weighted noses in the dstl 22 and other flares

Answer 11

To increase inertia and thus reduce the declaration of the payload.

Stainless steel provides high mass and corrosion resistance. It is bonded to the end of the flare payload and stays with it throughout its trajectory

Question 12

What is the roll of the alloy wrap

Answer 12

1. Environmental seal for it pellets
2. Promotes primer propagation by acting as a monetary gas seal
3. Safety function to prevent inadvertent ignition

Question 13

What is the CEOFE.

Answer 13

It is used to rupture the frangible disk on the fire exstingusher. Allowing stuff to flow under it’s own pressure. Each CEOFE has dual squibs each provides sufficient energy to propel slug.

Question 14

What is the role and how does the cartridge impulse - ARD 863-1A1W work.

Answer 14

It is used to eject various stores and release equipment from aircraft at bombs, fuel tanks, launchers, racks, pylons and other EO

a bridge wire is electrically inflated causing it to become incandescent causing the ignition composition to ignite, inturn ignites the propellant charge. High pressure operates the store release /ejector mechanism.

Question 15

How and what does a sequencer do

Answer 15

Is to ignite IR Pellets only after they have cleared the dispenser. Ignition is positively prevented whilst the payload is being ejected.
