Terminal Ballistics Research Laboratory (TBRL)

Terminal Ballistics Research Laboratory (TBRL)

Historical Background
Terminal Ballistics Research Laboratory (TBRL) was envisaged in 1961 as one of the modern armament research laboratories under the Department of Defence Research & Development. The laboratory became fully operational in 1967 and was formally inaugurated in January 1968 by the then Defence Minister. While the main laboratory is situated in Chandigarh, the firing range, spread over an area of 5000 acre, is located at Ramgarh in Haryana, 22 km away from Chandigarh. Over the past three decades, the Laboratory has grown into an institution of excellence and has become one of the major technical bases in the field of armament studies in DRDO.

The Laboratory facilitates basic and applied research in the fields of high explosives, detonics and shock waves, evolving data and design parameters for new armament stores and assessing terminal effects of ammunition under indigenous development/foreign origin.

Achievements
Battle Range for Small Arms
TBRL has designed battle range for practicing small arms firing. This has reduced the area required as compared to conventional range. Consultancy for construction of such ranges is being provided to various units of Army/Para-military forces.

Indigenous Plastic Bonded Explosives
Developed and established technology for Plastic Bonded Explosives (PBX), the latest class of HE compositions with high VOD and higher detonation pressures

Indigenous Digital Blast Data Recorder
This recorder was developed based on a new design technique, for direct measurement of important blast wave parameters

Indigenous Transducer for Blast-Measurement
Developed a blast pressure transducer for measuring pressures upto 14 kgm sqcm. It has a sensitivity of 1400 pc/kgm sqcm with a natural frequency of 200 KHz. These transducers are in regular production and being used by a no. of Laboratories. Impulse Generator : It has been developed for the simulation of impulse noise (=190 dB ) and testing of artificial earplugs used by Armed Forces Medical Services

Bund Blasting Device (BBD)
Designed and developed Bund Blasting Device for breaching operation.

General Purpose Anti-personnel Grenade
Multi-mode hand grenade designed and developed with reliability >95%.

Riot Control Non-lethal Bullet
Designed and developed a non-lethal ammunition in two service calibres, viz. 7.62 mm and .303-inch for effective control of unruly rioting mobs.

IGLOO Magazine
A new construction technique of laced reinforced concrete construction in which continuous bent shear lacing alongwith longitudinal reinforcements on both faces of structure element are used for improving the ductility and energy absorbing capacity of the structure has been developed for a capacity of 5 Ton explosives. This design is being used by a no. of DRDO labs, Ordnance factories, DGQA and service depots.
