Reference excerpt

High Energy Materials Research Laboratory (HEMRL) is one of the premier laboratories of the Defence Research and Development Organisation (DRDO) located in Pune Maharashtra. Main area of works of the lab include research and development of high energy materials and related technologies. HEMRL is organised under the Armaments Directorate of DRDO. The current director of the lab is Dr A P Dash. HEMRL has a core strength of 600 personnel, comprising chemists, physicists, mathematicians, chemical, mechanical and electronic engineers. It is recognised as a postgraduate centre for basic and applied research and is an ISO-9001:2015 certified laboratory.

History The precursor to HEMRL was the Chemical Examiner's Office which was established in 1908 at Nainital. In 1960, it was renamed as Explosives Research & Development Laboratory (ERDL) and was located in Pashan, Pune. In 1963, it was placed under DRDO control as a full-fledged R&D laboratory. ERDL was renamed as HEMRL in March 1995 in order to emphasise its work in all aspects of high energy materials research.

Areas of work HEMRL is the main DRDO laboratory and one of the few labs in India that is involved in basic and applied research in all areas of high energy materials. Under this mandate, it conducts R&D in formulation, design and development of propellants, high explosives, pyrotechnics, polymeric materials, liners/insulators, and other materials. These include studies on the physiochemical and combustion characteristics of materials, the study of detonation phenomena and the development of new systems. HEMRL also carries out the synthesis of new explosive materials and compounds of importance in the field of HEMs. Design and development of pilot plants for synthesis of high energy materials and related non-explosive chemicals is also carried out. After the development of technologies and products, HEMRL is involved in the successful production and transfer of technology of these products to appropriate agencies.

Facilities In addition to a number of laboratory analytical instruments, HEMRL has state-of-the-art research and production facilities for the study of explosive, propellant and pyrotechnic phenomena. These include facilities for Measurement of flame intensity and temperature, study of detonation phenomenon, determination of mechanical properties of propellants & polymers and facilities for static Rocket testing and Non destructive testing of materials. HEMRL also has labs and pilot production plants for synthesising high energy materials and their allied chemicals.

Projects and Products HEMRL handles different projects for the Indian Ordnance Factories, Indian Armed Forces and other organisations like BARC and the Indian Space Research Organisation.

In 2024, HEMRL successfully designed and implemented an indigenous, cost-efficient manufacturing process for large-scale production of amorphous boron powder (BP) using metallothermic reduction of boric anhydride.

Technologies for civilian use In common with other DRDO labs, HEMRL also develops spin-off products for civilian use.

Air Regenerating Composition This composition is used for maintaining breathable air within a closed space. It regenerates air inside confined space by liberating oxygen and simultaneously absorbing carbon dioxide. It can be used in civil applications like rescue work in mines, fire/ toxic environments, toxic gas/chemical plant operation, mountaineering expeditions, complete air regeneration inside a spacecraft, under sea exploration and mining etc.

Chemical Kit for Detection of Explosives (CKDE) A compact, low-cost and handy explosive detection kit has been designed and perfected for field detection of traces of explosives. The kit yields a colour reaction, based on which explosives can be detected in minutes. It is used for identification of all common military, civil and home-made explosive compositions, and is being used by Police and BSF for the detection of explosives.

Indian CL-20 A new high explosive is in the making at a DRDO lab here that could replace other standard explosives of the armed forces such as RDX, HMX, FOX-7 and Amorphous Boron. Scientists at the Pune-based High Energy Materials Research Laboratory (HEMRL) have already synthesised adequate quantity of CL-20, the new explosive, in their laboratory. The powerful explosive can substantially reduce the weight and size of the warhead while packing much more punch. The compound, 'Indian CL-20' or 'ICL-20', was indigenously developed in HEMRL using inverse technology. CL-20, so named after the China Lake facility of the Naval Air Weapons Station in California, US, was first synthesised by Dr Arnold Nielson in 1987. CL-20 or Hexanitrohexaazaisowurtzitane is a Nitramine class of explosive which is more powerful than HMX which in turn is more powerful than RDX CL-20-based shaped charges significantly improve the penetration over armors and could potentially be used in the bomb for the 120-mm main gun mounted on the MBT Arjun tanks. The CL-20 in its reduced sensitivity enables easy handling and transportation and reduces the chances of mishap and loss to men, money, materials and machines.

Accidents On 25 April 2002, an explosion at a solid propellant processing unit and its resulting fire killed six HEMRL personnel, including two scientists. A court of inquiry was ordered. The explosion was due to sudden reaction between sensitive chemicals. On 30 September 2009 an explosion took place at this laboratory leading to suspension of explosives processing for a week.

Worked examples

Example 1 — a first encounter with High Energy Materials Research Laboratory

Start with the simplest possible case. Write down what High Energy Materials Research Laboratory claims or describes in one sentence, then invent the smallest concrete situation in which that sentence is true. In engineering, the smallest case is usually a single object, a single equation or a single measurement. Check that every symbol or term in your sentence has a meaning in that case.

Example 2 — changing one variable

Take the situation from Example 1 and change exactly one quantity: double it, halve it, or set it to zero. Predict what should happen to High Energy Materials Research Laboratory before you calculate. Comparing your prediction with the result is the fastest way to find out whether you understand the idea or only the words.

Example 3 — an exam-style question

Typical questions about High Energy Materials Research Laboratory ask you to (a) state it precisely, (b) apply it to given data, and (c) explain a limitation. Practise writing all three answers in under five minutes; the third part is what separates a full-mark answer from an average one.

Applications of High Energy Materials Research Laboratory

In research: High Energy Materials Research Laboratory appears in engineering research whenever the underlying quantities have to be modelled precisely. Papers usually cite it as a starting assumption and then explore where it breaks down.
In technology and industry: Engineering practice reuses High Energy Materials Research Laboratory in design rules, simulations and safety margins. Knowing the idea lets you read a specification sheet and understand why the numbers look the way they do.
In the classroom: High Energy Materials Research Laboratory is common in secondary-school and first-year university syllabi. It links to neighbouring topics 1960 establishments in Maharashtra, Defence Research and Development Organisation laboratories, Materials science institutes, so understanding it makes those chapters shorter.
In everyday life: Look for High Energy Materials Research Laboratory outside the textbook — in sport, cooking, traffic, electronics or the sky above you. An example you found yourself is remembered far longer than one you were given.
