Aartech will supply uncapacitor-based systems to Indian Army


Aartech Solonics Limited has bagged the order to supply its state-of-the-art KranKing Uncapacitor based systems for ‘A’ Vehicles. These systems will prove extremely effective for the operations of tanks/ ICVs particularly in High Altitude Areas with extremely low temperature conditions in which batteries fail to perform. Having a 10x life, they can handle 100x number of charge-discharge cycles and can be charged almost instantly as compared to present day battery options in use. The system comes laden with various advanced features for testing, monitoring and protection. It includes independent energy harvesting sources to ensure engine starting in emergency situations. Aartech is a 30+ year old techno-preneurially driven company that works in the field of selected and specialized energy applications. It has the R&D facility recognized by DSIR (Department of Scientific & Industrial Research), DST, Govt of India. The company has pioneered in introduction of several innovations and system solutions such as power generation, transmission, distribution, defence, railways, continuous process industries, renewables and various other industrial applications in India and abroad.




India- third largest military spender


The latest data released by Stockholm International Peace Research Institute (SIPRI) says that, India is the third biggest military spender in the world, behind the US that spends more than 10 times and China that spends almost four times its defence budget. Total global military expenditure rose to $ 1981 billion in 2020, an increase of 2.6% in real terms from 2019 even as the global gross domestic product contracted by 4.4% due to Covid pandemic’s economic impact. It is clear that the pandemic didn’t affect global military spending in 2020. The top five big spenders also include Russia and the UK and together they account for 62% of the global military expenditure. China’s military expenditure grew for the 26th consecutive year. Its uninterrupted increase is by far the largest among the top 15 countries over the 2011-2020 decade. Pakistan got 23rd rank in the list. India’s annual military expenditure includes a huge pension bill for 33 lakh million veterans and defence civilians. In 2021-22 defence budget, the pension bill was Rs 1.15 lakh crore out of the total outlay of Rs 4.78 lakh crore. India maintains an over 15 lakh strong armed forces as it has two active and unresolved borders with China and Pakistan. Thus, the revenue expenditure for day-to-day running costs and salaries far outstrip the capital outlay for military modernization leading to critical operational shortages in different areas from fighters to submarines. Owing to military confrontation with China in Eastern Ladakh, India has made several emergency arms purchases from abroad. As per the SIPRI’s report, India’s defence expenditure can be attributed to its ongoing tensions over the Kashmir issue with Pakistan and renewed tensions with China. Add to it India’s general rivalry with China for being the main regional power in Asia and Oceania. Because of the weak domestic defence-industrial base, India continues to be the world’s second-largest arms importer just behind Saudi Arabia as it accounted for 9.5% of the total global arms imports during 2016-2020.

Armed forces will recall retired medics to work in Covid facilities


Chief of Defence Staff (CDS) General Bipin Rawat told Prime Minister Narendra Modi that retired military medical personnel or who took premature retirement in last two years are being recalled to work in Covid facilities in their area. This step comes at a time when the health emergency has groped the country and its resources are nearing a breaking point. Medical officers who retired more than two years ago have been requested to make themselves available for consultation through medical emergency helplines. While PM was reviewing the armed forces preparations to deal with the pandemic, he was told by the CDS that all medical officers on staff appointments at Command HQ, Corps HQ, Division HQ and similar HQs of the Indian Air Force and Navy will be employed at hospitals. Nursing personnel are getting employed in large numbers to assist doctors and oxygen cylinders available with the armed forces in various establishments will be released for hospitals. The Armed Forces have the manpower, resources and discipline to provide relief in such trying times. The military has a culture of quick response, be it against the enemy or natural catastrophe.




DRDO develops single crystal blades


Defence Research and Development Organization (DRDO) has developed single crystal blades technology for HTSE-1200 helicopter engine application. 60 of these blades have been supplied to Hindustan Aeronautics Limited (HAL) for their indigenous helicopter development program. Remaining four sets would be supplied gradually. The project by Defence Metallurgical Research Laboratory (DMRL), a premium lab of DRDO, involves development of five sets (300 in number) of single crystal high pressure turbine (HPT) blades using a nickel-based super alloy. DMRL used its expertise gathered during earlier development of such a technology for aero-engine project. Helicopters that are used in strategic and defence applications require compact and powerful aero-engines for their reliable operation at extreme conditions. These blades have complex shape and geometry and are capable of withstanding high temperatures. DMRL is equipped with the requisite applications and process such as complete vacuum investment casting to realize the blades along with die design, ceramic moulding, wax pattering, actual casting of components non-destructive evaluation (NDE), dimensional measurement and heat treatment. Strong ceramic moulds were made to withstand metallostatic pressure of liquid CMSX-4 alloy at 1500 degree Celsius and above. Casting parameters were optimized to maintain the required temperature gradient. The complex CMSX-4 super alloy was subjected to a multi-step vacuum solutionising heat treatment schedule so that it can assume the required microstructure and mechanical properties. The lab has also developed a stringent non-destructive evaluation (NDE) methodology for the blades and a special technique to determine their crystallographic orientations. Only few countries such as the USA, the UK, France and Russia have the capability to design and manufacture single crystal (SX) components used for helicopter engines. The efforts of DMRL were lauded by Defence Minister, Defence Secretary and DRDO Chairman.
