Demonstration – Blast Mitigation

SHIVA KAWACH
A path breaking blast mitigation technology

The Wonders are Evident

In order to test the efficiency and efficacy of Shiva Kawach, the technology was subjected to real time test situations in various demonstrations in tandem with field formations of the Indian Army as well as controlled explosions at Terminal Blast Research Laboratories, the testing and certifying arm of DRDO.

TEST CARRIED OUT ON NON-ARMOURED VEHICLES

Following the National Award in 2012, the Ministry of Home Affairs released a few non armoured (TATA 1212) trucks to further check the capability of Shiva Kawach.

Various such tests (and incremental developments) during the subsequent years culminated in a live animal test being conducted at TBRL in 2019 where live animals (rats & rabbits) were placed in the carriage area of a (TATA 1212) truck. The carriage area of such vehicles which generally ferry our jawans is at a height of 1200 mm from the ground. A 10 Kg TNT charge was placed flush with the ground under the carriage area of the truck (to simulate real time IED explosion) and detonated after conforming to well laid out procedures.

The floor of the truck had been secured with Shiva Kawach securely installed at the underbelly of the floorboard so as to be the line of defence between the explosive and the live animals.

Procedure followed for the test:

A standard non-armoured TATA 1212 was requisitioned from Ministry of Home Affairs.
Live and sedated rabbits (2 numbers) and a number of rats were placed in the carriage section of the truck.
Shiva Kawach was placed duly secured at the bottom surface of the floor board of the truck.
A 10 Kg TNT charge was placed flush with the ground under the carriage area of the truck, at standoff of 1200 mm from floor board
The charge was detonated, with the detonator placed at the bottom centre of the charge facing upwards to maximise blast effect on the truck.

Astonishing Results:

Lives Were Safe:

Shiva Kawach effectively & incontrovertibly deflected a major force of the blast away from intended target (live animals) and kept them out of harm’s way even though a significant explosion had gone off at only 1200 mm distance.

Post blast condition of live sedated small animals. — The rabbits in the carriage area of the truck were safe and unharmed as seen in the pictures. Rabbits were secure and suffered no short term or long term consequences as a result of the episode.

These animals were kept under observation for 28 subsequent days and they did not show any damage or abnormal behaviour.
Post the study period of 28 days a female rabbit from the test went on to conceive and deliver healthy babies.
Medical tests, MRI’s and X-ray’s of the subject animals exhibited no internal damage or post blast trauma.
Hence, Shiva Kawach not only saved the animals from blast effect but even safeguarded the animals from post-traumatic blast injury.

DEMONSTRATION ON VEHICLE’S FLOORBOARD

Additionally to verify the claims and capabilities of Shiva Kawach to the floorboard of the vehicle, a 10 Kg TNT charge was detonated at a standoff of 1.2 meters from a 3 mm MS plate held firmly in place in a special facility at TBRL in what is called a rigid wall test.

Two tests, one with Shiva Kawach installed and the other unprotected (control test), were conducted with similar charge, similar orientation of charge and similar standoff.

The results of the two tests are exhibited below

With Shiva Kawach

3mm thick MS Plate exposed to blast of 10 Kg TNT at 1.2 meters standoff, with Shiva Kawach protection

3mm thick MS Plate protected by Shiva Kawach, withstanding the 10 Kg TNT blast at standoff of 1.2 meters.

From the 10 Kg Explosive side. 3mm thick MS Plate protected by Shiva Kawach is evenly bent by 0.06m (60mm).

Without Shiva Kawach

3mm thick MS Plate exposed to blast of 10 Kg TNT at 1.2 meters standoff, without Shiva Kawach protection

Instant rupture of 3mm thick MS Plate exposed to blast of 10 Kg TNT at 1.2 meters standoff.

3mm thick MS Plate was cut in two equal pieces one flew 400 meters away one 35 meters away
