SAD-(40mm)-2
SAD (M-802) Closed

FUZE 447

1. The sophisticated fuze has a number of safeties which are removed by set back and centrifugal forces developed on ammunition firing. The time for functioning of the fuze is easily set by the soldier which makes the ammunition function in air burst mode, at a pre-set time.
2. The fuzehas distinct sections of clock-work mechanism, centrifugal safety device and detonator safety device. Though design is intricate due to additional safeties yet it is reliable and effective. The fuze functions in air burst and direct action modes.
3. Having more number of safeties, the fuze is very safe in storage and transportation.

Characteristics Time Mechanical Fuze
Usage HE ammunition fired from shoulder mounted 84mm RCL Gun
Metal Mainly Aluminium
Weight 720 g
Number of components 127
Dimensions ɸ84 × 120mm

 

Fuze-213-2

FUZE 213 MK5 (M-3)

1. On firing, set back force releases the plunger, which in turn allows the hand to move. At a pre-set time, the hand drops intothe cavity of the dome which releases the striker to initiate the ignition train.
2. This fuze also functions in Percussion mode on nose hit at the terminal end.
3. The setting for its functioning is made upto 80 seconds with steps of 0.5 seconds.
4. It is a Time Mechanical fuze, kept in safe marked position and provides safety in handling, transportation and storage. It is easily operable by soldiers.
5. The fuze functions in reliability of ± 1% from set time.

Characteristics Nose fuze, functioning on Time and Percussion mode
Usage Bomb 81mm Illuminating
Metal Aluminium Body houses the clockwork mechanism – mainly made of brass components
Weight 615 g
Number of components 84
Dimensions ɸ60 × 117mm

 

Fuze-117-2

FUZE PERCUSION DA NO 117

1. On fire,the sleeve and segments holding the striker are operated due to set back and centrifugal forces. The striker motion releases the weight, which gets into armed condition. The safeties being released, the striker on impact impinges on the detonator, setting the detonation wave to be activated.The fuze functions even at a low angle of impact.
2. The fuze, acting in Direct Action mode, is simple in design but rugged and reliable.
3. The mechanical safeties are released by set back and centrifugal forces which otherwise keep the fuze in a non-functional state.

Characteristics Nose fuze operating in Direct Action mode
Usage Artillery ammunition 105mm IFG HE
Metal Mainly Brass
Weight 1140 g
Number of components 22
Dimensions ɸ60 × 127mm

Fuze-DA5A-2

FUZE DA 5A

1. On fire from the mortar, set back force releases the mechanical safeties of the detent, ball and shutter. On direct impact, the striker initiates the explosive train for the bomb to function at the terminal.
2. The fuze provides mechanical safety to the ammunition in handling, storage and transportation.
3. Simple in design but rugged in construction, the fuze is reliable in operation and safety.

Characteristics Nose Fuze; simple in design
Usage 51mm HE Mortar Bomb
Metal Mainly Aluminium
Weight 270 g
Number of components 21
Dimensions ɸ51 × 82mm

 

Fuze---162-2

FUZE 162 MK8 (M-2)

1. On firing, set-back force pushes the detent, allowing the steel ball to roll down,which releases the striker to push forward. The shutter moves out of its safe position and the detonator housed in the shutter is brought in armed position. On direct impact at target, the striker hits the detonators, setting out the ignition train.
2. The design of the fuze is simple yet effective and reliable.
3. The safety cap protects the wind shield and the striker additionally during storage and transportation.

Usage 81mm smooth bomb Mortar HE ammunition
Metal Mainly Brass
Weight 505 g
Number of components 16
Dimensions ɸ38 × 91mm

 

SAD-(40mm)-2
SAD (M-802) Closed

SAFETY AND ARMING DEVICE

1. SAD is an integral part of Electronic Fuzes, providing mechanical safeties in addition to electronic safeties in the fuze.
2. The set-back force pushes the Detent down, while the centrifugal force makes the two detents retract, which unlocks the rotor gear making it free to move. Centrifugal force causes off-centre rotor mechanism to rotate, bringing the detonator in the line of fire.
3. The electronic trigger mechanism and micro electric detonator are amplified by the detonator set in the rotor.

Usage Any of 105mm, 130mm and 155mm 52 calibre gun ammunition
Metal Mainly Brass

 

MTD_02-2

MTD

1. MTD is an inexpensive, safe and fool proof method to train the crew to handle 81mm Mortar HE Ammunition. The device is used with sabot, which not being destructed can be used for 1000 firings.
2. On firing, cartridge alongwith sabot assembly is ejected from the mortar and while sabot after a short distance of 2-3 m detaches projectile follows the trajectory desired.
3. Function of the device is observed as smoke, sound and Flash at the set target.

Usage Training of crew members to simulate handling and loading of 81mm mortar HE bomb
Metal Aluminium and Brass
Weight 470 g
Number of components 16
Dimensions ɸ39 × 230mm

STABILIZER ASSEMBLY

1. The fin blades are kept in a close position by the polymer ring. On firing, the ring is broken while the shell comes out of the barrel, making the blades free to move. The centrifugal force makes the fin blades to fly out, giving stability to the shell during flight.
2. Simple design makes assembly easy to function.

Usage 125 mm HE ammunition
Metal Aluminium Alloy body and steel blades
Weight 3437 g
Number of components 5
Dimensions ɸ128 × 211mm

 

Primer-Electrical-1A-2

PRIMER 1A

1. Primer, used to ignite propellant charge, is operated electrically. The electric current ignites Cap of the primer while the gun powder in it magnifies the igniferous power which in turn ignites the propellant charge.
