Multi-Mode Hand Grenade - Shivalik

Modular in design: Two modules, i.e, fuze and main body, light in weight: Gross weight is 490 g in defensive mode and 260 g in offensive mode.

Serves as both Offensive and defensive grenade i.e Lethal radius of 3 to 5 m from point of burst in offensive mode. In defensive mode, it incapacitates human being with in the radius of 8-10 m from the point of burst Uniform fragmentation pattern. More number of fragments (>4000) embedded in plastic matrix to provide higher splinter density of fragments. Time delay 3 sec and arming delay of 0.5 sec provides additional safety to the thrower. Maintenance free and highly reliable. Operational temperature range of -20 ºC to 55 ºC and storage temperature range of -50 C to 75 C .

Mechatronic fuze for multi-mode hand grenade operates in three modes, viz., time delay, impact, and dual. Pre-launch safeties have been provided through mechanical components whereas post launch safeties and intelligence have been incorporated using embedded system based electronic hardware and software. The detonator is misaligned with the rest of the explosive train during storage and transportation. The fuze is powered by primary lithium battery. The fuze has been designed to withstand accidental drop for thrower’s safety. The time delay for arming and initiation of detonator is factory settable with a high precision. The fuze has a provision of self-discharge system to avoid delayed initiation after a preset delay.

AMCA is envisioned to use carbon-fibre composites (C-FC), and titanium alloy steels for airframe construction. C-FC materials will be used in 80% of airframe by weight. It will also be used in the fuselage (skins and doors ), wings (ribs , skin, and spars), tailfin, elevons, rudder, air brakes and landing gear doors. The advantage of using composite materials is that it makes an airframe lighter and stronger at the same time compared to an all-metal design. AMCA is supposed to employ the highest percentage of composite materials for any other aircraft. Employment of composite materials helps in the fact that there are fewer joints and rivets, which increases the aircraft’s reliability and lowers its susceptibility to ural fatigue cracks in its structure with the majority of these being bismaleimide (BMI) and composite epoxy material. AMCA will also use structural nanocomposites, namely carbon nanotube reinforced epoxy. Stressed ducts in S-shape are rivetted with airframe with the loaded bulkheads constructed off composite materials spanning the aircraft from air intake to engine shafts.

toss bombing’ or the ‘over-the-shoulder maneuver,’ is accomplished by flying towards the target at a lower altitude, pulling up to a sharp vertical plane and releasing the bomb just past vertical while executing a loop, essentially ‘throwing’ the bomb back toward the target compensating for the gravity effect on the bomb(s). This tactic allows the pilot time to put sufficient distance between his aircraft and the target before the bomb exploded.

And these ( or something like this ) is what the IAF mirage 2k most probably does with its gravity nuclear bombs the picture of which I had previously posted long ago .

Haven't these gravity bombs been discarded with new precision bombs arriving?
