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.

penetrate up to 150 mm of armour
Rocket 66mm HEAT M72A6
describe the function of the fuze
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)
Cart 84mm ASM 509
Describe the Cart 84mm ASM 509
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
Cart 84mm ASM 509
operation in flight and impact
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
Cart 84mm ASM 509
what is the Fail safe mechanism
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
