Defence Research and Development Organisation (DRDO) has established the near isothermal forging technology to produce all the five stages of high-pressure compressors (HPC) discs out of difficult-to-deform titanium alloy using its unique 2000 MT isothermal forge press. The technology has been developed by the Defence Metallurgical Research Laboratory (DMRL), a premier metallurgical laboratory of DRDO at Hyderabad. This is a crucial technology for establishing self-reliance in aero-engine technology. With this development, India has joined the league of limited global engine developers to have the manufacturing capabilities of such critical aero-engine components.
To meet the bulk production requirements, DMRL technology was transferred to M/s MIDHANI through a licensing agreement for technology transfer (LAToT). Using the isothermal forge press facility available at DMRL, Hyderabad, bulk quantity (200 numbers) of HPC disc forgings pertaining to various compressor stages have been jointly (DMRL & MIDHANI) produced and successfully supplied to HAL (E), Bengaluru for fitment into Adour Engine that powers the Jaguar/Hawk Aircrafts.
In India, the Adour engine is overhauled by HAL (E), Bengaluru under a licensed manufacturing agreement with OEM. Like in any aero-engine, the HPC Drum assembly has to be replaced after a specified number of operations or in case of damage. The annual requirements of these high-value HPC discs are quite large, warranting indigenisation. HPC drum is a highly stressed sub-assembly and is also subjected to low cycle fatigue and creep at elevated temperature. The raw materials and forgings for the HPC drum are required to be of the highest quality which can meet the specified combination of static and dynamic mechanical properties.
DMRL developed this forging technology by integrating various science and knowledge-based tools. The methodology adopted by DMRL is generic and can be tuned to develop other similar aero-engine components. The compressor discs produced using this methodology met all the requirements stipulated by the airworthiness agencies for the desired application. Accordingly, the technology was type certified and a letter of technical approval (LoTA) was accorded. Based on the exhaustive component level and performance evaluation test results, HAL (E) and Indian Air Force cleared the components for engine fitment. Apart from DMRL and HAL (E), various agencies such as MIDHANI, CEMILAC and DGAQA worked in unison to establish this crucial technology. Raksha Mantri Rajnath Singh has congratulated the scientists of DRDO, Industry and all other agencies involved in the development of this critical Aero Engine related technology. Secretary Department of Defence R&D and Chairman DRDO Dr G Satheesh Reddy expressed his satisfaction on achieving this crucial milestone and congratulated the teams involved.

Major push to Make in India in defence sector
To give a major push to Prime Minister Narendra Modi’s Atamanirbhar Bharat mission, the Indian Army has joined hands with various technology firms to cater to the demands of the present security scenario.
The Army says if it has to remain operational all around, it cannot rely on obsolete technology hence latest advancement in the sector have to be adopted.
“The Northern Command is always combat ready in the times to come, the challenges will continue to increase so we have to rely on advance technology and keep on innovating,” Lieutenant General Upendra Dwivedi told The Daily Guardian on the sidelines of the Northern Technology Symposium held in Udhampur on Sunday.
North Tech Symposium was organized under the aegis of HQ Northern Command at Udhampur. Technology symposium, exhibition was organised wherein 162 companies from Indian defence industry including MSMEs, DRDO, DPSU, participated and exhibited their products.
In addition, 42 innovative solutions by Army establishments towards enhancement of combat potential of the Army were also on display. Lt Gen BS Raju, Vice Chief of Army Staff inaugurated the first of its kind technology symposium in Jammu and Kashmir.
Addressing the event, vice-chief of Army staff Lt Gen V S Raju said that he would have appreciated if the investors, capital ventures would have also shown interest in the event to boost the new start-up.
“To cope up with the ever-evolving and ever-changing security scenario, we also need to adopt changes and keep on innovating. I am happy that so many companies have shown interest to showcase their products at the North Tech Symposium. I am hopeful that in near future, many of the products would be put in use by the armed forces,” General Raju said.
In the wake of recent incidence of drone dropping in Jammu and Kashmir and Punjab from across the Indo-Pak border, various companies have displayed their products including anti- drone system, drone jammer which can strengthen the forces and border guarding forces to thwart Pakistan’s plan of disturbing peace.
Other than drone dropping threats, detection of tunnels on Jammu and Kashmir border is also a major threat for the security forces these days as 11 tunnels have been detected on Indian-Pakistan border in the past few years. There was number of companies which showcased their products to detect underground tunnels by using artificial intelligence and special radar.
The symposium saw active participation from of senior officers from different forces including IDS, Army HQ, HQ ARTRAC, other Commands, HQ Northern Command, and its subordinate formations. This interactive platform for knowledge diffusion through Joint Army-Industry participation was an important step in the direction of the government’s initiative of “Make in India”.
On the first day of the seminar, the participants from Army and industry discussed the policy and procedures for expeditious procurement, Raksha Atmanirbharta initiatives by Indian Army, DRDO and Defence Public Sector Undertakings, how can private sector contribute towards surveillance system, weapon sights, drones and counter drone system and miscellaneous technologies like 3D printing.
The symposium served to showcase cutting edge technologies and innovative products providing solutions to some of the complex challenges faced by the security forces in Northern Command and also acted as an ideal platform for mutual exchange of ideas between the domestic defence industry and the Army. The technologies and products on display covered a wide canvas, the prominent ones being surveillance and situational awareness, tactical mobility, firepower, force protection, communications, combat medical facility, robotics and simulators.
The symposium was a huge success and Lt Gen Upendra Dwivedi, AVSM lauded the initiative and innovations of all the vendors. The General Officer expressed his conviction that the plethora of technologies available indigenously can further boost the “Atmanirbhar Bharat” project of the nation. The spirit of Atmanirbharta demands that research and development, the domestic defence industry and Army have work in a synchronized manner to realise the nation’s vision.
ARMY MAJOR SUCCUMBS TO INJURIES DURING OPERATION IN KASHMIR
An Indian Army Major lost his life after slipping into a ravine during a counter-infiltration operation in the Uri sector of Jammu and Kashmir on Thursday.

FOR 114 FIGHTER JETS, IAF FAVOURS ‘BUY GLOBAL MAKE IN INDIA’ ROUTE
For over USD 20 billion tender for manufacturing 114 multi-role fighter aircraft (MRFA) the Indian Air Force (IAF) would prefer to take the ‘Buy Global Make in India’ route over the strategic partnership policy model to produce the planes within the country.
‘Buy Global Make in India’ is a category of procurement process provided in the Defence Acquisition Procedure 2020 under Defence Minister Rajnath Singh to smoothen the acquisition of foreign weapon systems and their production within the country under the ‘Make in India’ in the defence programme. Along with the indigenous LCA Tejas and the 5th Generation Advanced Medium Combat Aircraft project, the 114 MRFA project would also be required by the IAF to maintain an edge over both the Northern and Western adversaries. We would prefer to go in for the Buy Global Make in India route which is preferred by the vendors also who are expected to take part in the programme, government sources said. Three American aircraft including the F-18, F-15 and F-21 (modified version of the F-16), Russian Mig-35 and Su-35 along with the French Rafale, Swedish Saab Gripen and the Eurofighter Typhoon aircraft are expected to participate in the programme. The Indian Air Force had also sought the views of these companies on the acquisition procedure that they would like to opt for in the programme and most of them have shown a preference for the Buy Global Make in India route only, they said.
The sources said that the force has also sought directions from the government on the project.
INDIA GETS DEFENCE SUPPLIES FROM RUSSIA, BUT PAYMENT MAY BECOME AN ISSUE
Amid the ongoing war between Russia and Ukraine, defence supplies from Moscow are continuing as the Indian defence forces have received a shipment of overhauled aircraft engines and spares. However, there is concern about whether this would continue in the near future as a solution for making payment to Russia has not yet been found.
“The defence forces have received shipments from the Russians very recently and it is still on. So far, there has not been any glitch in supplies for our forces,” a government source told ANI.
“However, there are concerns on whether these supplies can continue in the same manner as the Indian side cannot make payments to these Russian firms in view of the sanctions related to their banks,” he added.
The sources said the Indian and Russian sides are working to find a way this issue can be overcome and many options are being explored.
The latest supplies from Russia included overhauled fighter aircraft engines and spares for an aircraft fleet and they arrived through the sea route, the sources said.
India also received the final parts of the S-400 Triumf air defence system from Russia whose first squadron is operational with its elements deployed to take care of threats from both Pakistan and China.
India is one of the largest users of Russian weaponry including major platforms like fighter jets, transport aircraft, helicopters, warships, tanks, infantry combat vehicles and submarines.
Over the last couple of decades, it has broadened its source base by including equipment from countries like the US, France and Israel in a big way but the dependence on Russia still remains very high.
The Air Force is dependent majorly on the Russian supplies as its mainstay Su30 aircraft fleet is Russian along with its Mi-17 helicopter fleet.
The Army is also dependent on the Russian-origin T-90 and T-72 tank fleet for the armoured regiments.
IAF, ARMY BRASS WILL ASSESS LAC SITUATION
The top brass of the Indian Army and Air Force would be assessing the preparedness of their forces and infrastructure requirements along the Line of Actual Control (LAC) as the militaries of both India and China continue to remain in a standoff position in eastern Ladakh.
The Indian Air Force brass would be meeting this week from 6 April to discuss the security situation including air operations along the northern borders. The Indian Army commanders led by Army Chief General Manoj Mukund Naravane would be assessing the present deployments along eastern Ladakh and the northeastern sectors from 18 April onwards in the bi-annual commanders’ conference.
The top brass of the Indian Army had jointly discussed the infrastructure requirements and developments required by the Indian side from Ladakh to Arunachal Pradesh during a conference in Lucknow recently.
India has made several changes in its deployments post aggression shown by Chinese troops in April-May 2020.
India and China have been talking to each other at both military and diplomatic levels to address the issues but so far they have not been able to do so mainly because of Chinese reluctance. In recent talks to address the Patrolling Point 15 friction, they proposed a solution that was not acceptable to the Indian side.
Indian security establishment led by National Security Adviser Ajit Doval has been of the view that the issue would be resolved only if the Chinese completely disengaged and went back to pre April 2020 positions.The Indian side has strengthened its deployments manifold all along the LAC. The Indian Air Force has also started building advanced bases in the forward areas including infrastructure to operate fighter jets and attack helicopters from the forward fields such as Nyoma.
Sharp fall in infiltration of foreign terrorists, stone pelting: CRPF DG
There has been a sharp decline in the infiltration of foreign terrorists as well as in stone-pelting incidents in Jammu and Kashmir since the abrogation of Article 370 from the erstwhile state, Director General of Central Reserve Police Force (CRPF) Kuldiep Singh said on Thursday.
However, noting the targeted killings in Jammu and Kashmir, the officer said, “Some time there is a spurt in terrorist incidents” and the recent killing in “periodic series” are among those, and “it occurs”. Replying to queries during a press briefing here at the CRPF Headquarters, Singh said, “CRPF immediately try to control terrorist incidents in Jammu and Kashmir soon after it gets inputs. These incidents are not totally controlled by internal terrorist people who are there. On many occasions, it is controlled by those sitting across the border and it is directed whom to be targeted or not.”
The CRPF DG reiterated that “some directions comes from foreign lands too”, and thus, “terrorist incidents some times increase and sometimes decrease” “It does not mean that things are out of hand…You can see that the incidents of stone-pelting are almost nil. There has been a sharp decline in the number of infiltration of foreign terrorists into Jammu and Kashmir. Sometimes, there is a spurt in terrorist incidents but it happens,” he said.
The officer informed that the CRPF has neutralized 175 terrorists in Jammu and Kashmir and apprehended 183 from March 1, 2021, to March 16, 2022.
Meanwhile, the CRPF has recovered 253 arms from Jammu and Kashmir and seized 7,541 ammunition as well as 96.38 kg explosives, 23 Improvised Explosive Device (IED), 232 grenades, and 36 detonators from the Union Territory, Singh said. Further, he informed that as many as 91 encounters have taken place from March 1, 2021, to March 16 this year. CRPF is the premier Central Armed Police Force (CRPF) entrusted with the responsibility of safeguarding the internal security of the country. It is deployed across the length and breadth of the country, assisting various state police in the discharge of their duties. CRPF is providing security cover to 117 protectees of various categories, he said adding that 32 women personnel have been inducted into the VIP Security Wing.
A total of 41 VIPs were provided security cover by the CRPF during recently concluded Assembly elections in five states, the DG said adding that the security of 27 protectees has been withdrawn post-elections. The CRPF chief also said that under financial assistance from the risk fund, ex-gratia for personnel martyred in action has been increased to Rs 30 lakhs from Rs 20 lakhs, and for all other cases, the ex-gratia has been increased to Rs 20 lakhs from Rs 15 lakhs.
