Answer 3

• Illuminant Assembly

- Mounting Bracket Assembly

Question 4

Describe the complete functioning of the Flare Surface Trip A301 when set up for ‘Pull Pin’ operation

Answer 4

• Tension on the trip wire causes the pull pin to be removed, which allows the lever to fly up under spring tension
• The striker mech impacts the percussion primer in the fuze assembly
• The percussion primer initiates the ignition transfer charge, which then ignites the flare priming composition on the surface of the flare pellets
• The fuze assembly ejects from the case and the flare burns to completion

Question 9

Describe ‘Actions upon Release’ for the LUU 2A/B Flare

Answer 9

• Timer knob pulled by lanyard and clock activated
• Clock mechanism initiates release spring, ejecting timer assembly
• Timer assembly deploys para chute
• Force of the chute applies force to ignition lanyard, activating flare ignition system and igniting candle
• Case and candle are consumed and an explosive bolt is initiated collapsing canopy and Flare falls to the ground/sea

Question 10

Question 12

What is the light intensity of the candle of the Flare Aircraft LUU 2 A/B when functioned

Answer 12

2,000,000 candlepower

Question 13

The Marker Marine AN25 MOD 3 will activate in fresh water? True/False

Answer 13

False

Question 14

Describe the functioning of the Marker Location Marine Mk 58 Mod 1 from the Activation phase

Answer 14

• Sea water enters the battery cavity hole and serves as an electrolyte to activate the Mk 72 mod 1 battery
• Current from the battery initiates the Mk 13 mod 0 squib which ignites the starter mix of the first pyrotechnic candle. The starter mix, inturn, ignites a transfer time fuse which carriers ignition to the second candle starter mix which ignites the final burning.
• Each candle, in the marker, burns for a minimum of twenty minutes

• Signal Carrier
• Signal Composition

Question 19

The Sig Illum M125A1 emits 9000 candlepower on function, how much candlepower does the M127A1 emit

Answer 19

125,000 candlepower

Question 20

Question 26

What are the two grades of cart 12.7mm MP NM140 Raufoss and what is the difference between the 2

Answer 26

- Grade A and Grade B | - Grade A manufactured to a higher tolerance

Question 27

Explain the operation of the projectile 12.7mm MP NM140 Raufoss from impact

Answer 27

- Nose of the projectile is compressed and the incendiary ignited. - Projectile passes through the target - Pressure continues to build up within the nose - The incendiary composition ignites the high explosive - Increase in pressure-deflagration turns to detonation, producing a blast and fragments - The second incendiary charge then ignites and burns for approx. 1 second
