What is Charge block 600g used for??

A

used for dems and material destruction
also used as an initiating charge for other items of ordnance
initiated by 38g primer

41
Q

Charge block 600g

what is the warning on the Charge block 600g ?

A

Exudation of MNT/DNT/TNT isomers and/or TNT/Comp B High Explosive (HE) can occur as it
deteriorates with age and/or is exposed to elevated temperature. The exudate is friction and crush
sensitive and may form a potential ‘flash path’. It also poses a Toxicity Hazard during handling i.e.
dermal exposure path.

AP capabilities of the Rocket 66mm HEAT M72A6

A

penetrate up to 150 mm of armour

47
Q

Rocket 66mm HEAT M72A6

describe the function of the fuze

A

Operation of the M412A1 Fuze
- On setback, leaves disengage - rotor turns clockwise - rate retarded by a geared escapement
- after set back, fuze arms - safe arming distance of 12m
- spring loaded escapement winds down (0.67 sec)
- When armed, rotor aligns the electric detonator to the firing block contacts and the graze action
cocked striker. Both detonators align with the fuze booster pellet, achieving explosive train
alignment
- On impact
o The ceramic piezo-electric crystal element in the windshield is crushed
o Produces an electric charge, transmitted via internal wires within the inner cavity of the
warhead - initiates the detonator
o This detonates the fuze booster pellet - detonates the warhead charge (from the rear)

48
Q

Cart 84mm ASM 509

Describe the Cart 84mm ASM 509

A

anti structure munition` designed to defeat targets in light construction
can be used to engage with light armoured vehicles
shell is filled with blast enhanced explosive

49
Q

Cart 84mm ASM 509

operation in flight and impact

A

Arming Sequence
- Percussion cap initiated, igniting composition, propellant
- resultant gas pressure imparts motion to shell, and forces a pressure plunger located in the fuze
holder through a hole in the base disc located behind the detent pin of the SAI unit
- The pressure plunger moves the detent pin upwards, releasing the ball which in turn releases
the escapement locking pin
- Acceleration and the escapement locking pin spring force the escapement locking pin
downwards, releasing the escapement
- The main spring turns the rotor lock 180o to the unlocked position
- acceleration also forces the driving plunger downwards and the spring-loaded driving pin in the
rotor is released
- The driving plunger is blocked against the pin since the rotor cannot be turned - retained in its
position by the rotor lock that has not yet completed its 180o turn
- When the rotor lock has turned to the unlocked position and the acceleration ceases, the
plunger spring forces the plunger upwards, turning the rotor into the armed position
- Also - setback plate returns to the initial position against the grounding clip. This means that the
piezoelectric system is short-circuited even after the rotor has reached the armed position and
no current reaches the electric detonator.
Target Impact
- Upon impact, shock wave is generated that piezo-electric crystal converts into electrical energy
(sufficient to make the diode conductive)
- (I) mode
o diode closes the electric detonator circuit achieving initiation
- (D) mode
o system is short circuited preventing current from reaching the electric detonator
o The magnetic inertia pellet, which is attached to the base disc, is forced forward on
impact and strikes the delay detonator
o Delay detonator ignites and initiates the electric detonator. This gives a delay of about
30 ms

50
Q

Cart 84mm ASM 509

what is the Fail safe mechanism

A

if the escapement is released during transport or handling before the driving plunger is pressed down, the rotor lock will turn 260 degrees into the fail safe position
