DRDO Set To Break The Military Aircraft Engine Bottleneck

A modern after-burning turbofan design​

Kaveri engine development was an indigenous effort of Gas Turbine Research Establishment (GTRE) for mastering one of the most complex technologies. Altitude Testing and Flying Test Bed trials have been completed which are major milestones in any gas turbine engine development. The other development problems are addressed to make the engine flight worthy through indigenous as well with assistance from foreign engine houses.

All efforts have been made by Ministry of Defence (MoD), Defence Research and Development Organisation (DRDO), Defence public Sector Undertakings (DPSUs) & Ordnance Factory Board (OFB) to achieve self-reliance in critical technologies. The self-reliance has to spread across design, materials, manufacturing, testing and certification aspects of aero-engine and considerable progress has been made towards the same through the Kaveri engine development program.

The following DRDO laboratories are fully dedicated towards aeronautical research.
• Aeronautical Development Establishment (ADE) – Morphing Aircraft Technologies.
• Aeronautical Development Agency (ADA) – Aircraft Design & Development.
• Gas Turbine Research Establishment (GTRE) – Gas Turbine Aero Engines.
• Defence Research & Development Laboratory (DRDL) – Hypersonic Propulsion.
• Advanced System Laboratory (ASL) – Solid Propellant Combustion Modelling.
• Center for Airborne System (CABS) – Design & Development of Airborne Surveillance System.

A dedicated program on “Gas Turbine Enabling Technology (GATET) has also been sanctioned by DRDO at a cost of Rs. 78 Crores to facilitate academia and research institutions to carry out R&D in aerospace sector.

DRDO has made all efforts to augment aerospace technology capability of the country with dedicated research facilities at Indian Institutes of Technology (IITs), located at Mumbai and Chennai by creating ‘Centre of Propulsion Technology (COPT)’; and also at Indian Institute of Science (IISc) through ‘National Centre for Combustion Research & Development’ (NCCRD). Though the manufacturing is not the mandate of DRDO, however, research pertaining to various areas of manufacturing technology such as machining, metal forming, metal joining, etc. are being pursued in recent times through academia and R&D establishments and these are progressing well. Moreover, DRDO has involved academia and private industries right from the inception of project.

We are building jet engines: Baba Kalyani

Swaraj Baggonkar | Mumbai Feb 16, 2016 12:49 AM IST

Baba Kalyani, chairman and managing director of Bharat Forge, was visibly excited when Defence Minister Manohar Parrikar dropped in at his stall on Monday during the Make in India Week in Mumbai. On display was the Bharat 52, a long range artillery gun developed by the company. In an interview to Swaraj Baggonkar, he explains what Bharat Forge is doing in defence. Edited excerpts.

What are your plans for the defence business?

We are going in the direction that uses our core knowledge — material, material transformation, forging, machining, assembly, sub-systems. That’s where our expertise lies.

What are your investment plans?

We have a joint venture with SAAB for air defence systems and a plant is coming up near Hyderabad.

What are your capabilities?

By building the artillery gun, we demonstrated our engineering capability. We are building jet engines — small ones, not as big as those by Rolls -Royce — for helicopters and unmanned aerial vehicles.

Is the jet engine indigenous?

The UAV engine we are doing indigenously. I have told my engineers in Pune that I want to see the engine in one year.

How much is your focus on the defence business?

Quite a lot. Take the gun programme, for instance. There are four programmes under procurement: the towed gun, conversion of the 130mm to 155mm, ultra-light howitzer, and the mounted gun. We are participating in all four programmes. I am sure we will win at least two.

Is the government moving as fast as companies would have liked?

Our defence minister is a very dynamic person. He is driving the ministry in the direction of the prime minister wants, which is indigenous capability.

Will Bharat Forge look for expertise outside India?

We are already in technical alliances. We have three joint ventures; we may go in for more. You can’t do everything yourself, it is not possible. There is involvement of electronics, radar and all kinds of things. We do not have that technology, at least not today. Anything to do with metal–forging, fabrication or machining–we can do. But, the idea is you make a product that is 95 per cent indigenous.

What will be the investment on all this?

Our strategy is to create building blocks for guns, air defence, aero engines and components. Artillery we can make entirely ourselves. As far as air defence systems are concerned, we are creating a hub in Hyderabad. In aero engines, we are making components for Rolls-Royce, Boeing and others.

Indo-US Joint Working Group on jet engine meets

The Joint Working Group on Jet Engine Technology met last week at the Wright Patterson Air Force Base at Ohio.

NEW DELHI: India and the US have held yet another round of talks on possible collaboration in jet engine technology as both sides inch closer on the issue of defence cooperation.

The Joint Working Group on Jet Engine Technology met last week at the Wright Patterson Air Force Base at Ohio.

American Ambassador here Richard Verma said both sides had "productive discussions" for future collaboration.

However, sources said that India, which has not been able to get requisite power from its indigenous Kaveri engine for fighter aircraft, is seeking "hot engine" technology which the US considers as the crown jewel in the jet engine technology.

The sources said that the US is willing to help with the "cold engine" technology.

The new engine is likely to be for the Advanced Medium Combat Aircraft (AMCA) which is a single-seater, twin-engine fifth-generation stealth multi-role fighter planned by DRDO.

Meanwhile, the US has already updated its policy on gas-turbine engine technology transfer to India to expand cooperation in production and design of sensitive jet engine components.

Collaboration for jet engine is one of the key components of the ambitious Defence Technology and Trade Initiative (DTTI).

Ha Ha Ha ......

For sure the US will share you engine tech.

But the tech of the 1950's F86 Sabre engine : the GE J47 .....

What did you expect ?

There is not a single word of confirmation from Safran or Safran Aircraft Engines ( new name of SNECMA) about an agreement with GRTE regarding Kaveri development. So far it is only Indian medias who hint at such an agreement. And I learnt the hard way to be very cautious with Indian sources !

And I learnt the hard way to be very cautious with Indian sources !

Indeed, they report turbofan as ramjet.

By TOI
Bengaluru may give India its first jet engine; testing begins

HIGHLIGHTS

• Poeir Jets Private Limited is an R&D firm which can give India its first indigenous jet engine.
• The company decided to make its own gas-turbine engine only two years ago.
• The firm has earmarked Rs 20 crore for the project, of which about Rs 9 crore has been spent.

BENGALURU: In about 24 weeks, Bengaluru will know if it can give India its first indigenous jet engine.

Having developed its first jet engine -successful certification of which will put India in the elite group comprising only three other countries -a Peenya team of 11 engineers and scientists is busy preparing for its certification. Only the US, Europe (as one entity) and Israel boast of jet engines.

Poeir Jets Private Limited, an R&D firm under city-based Intech DMLS, has earmarked Rs 20 crore for the project, of which about Rs 9 crore has been spent. Leveraging its rich experience from tie-ups with firms such as HAL and Bharat Forge, the company decided to make its own gasturbine engine two years ago.

Intech founder and managing director Sridhar Balaram told TOI: "We fired the engine for the first time on February 8, 2017, and it was a success. Some other tests are going on, and we are confident that it will be ready to be presented for certification in 18-24 weeks."

He said MJE-20 is a gas-turbine engine which can power Unmanned Aerial Vehicles (UAVs) or Remotely Piloted Vehicles (RPVs). Weighing 2.16 kg and providing an uninstalled thrust of 20 kg, the engine will not be able to power UAVs of military grade. "It is for this reason that we will be ready for certification in 24 months. But the success we've seen has pushed us to develop bigger engines. We have the MJE-40 and MJE-100, which will be able to power bigger UAVs. Given that they are gas turbine engines, they will give longer flying hours," he said.

The firm has there other variants and the final one, SJE-350, which it believes can power bigger planes of strategic importance, weighs 48.36kg and provides an uninstalled thrust of 350kgf. However, experts said more thrust would be required to power fighter jets. Balaram said: "We are aware of that. While SJE-350 in a twin-engine configuration can power a fighter, we are also looking at helicopters, for which we are working on the turboshaft technology."

Aero India 2017: Indian Kaveri engine to be revived with French assistance

IDN TAKE: Development of Indigenous Turbofan Engines

The Kaveri Story

Kaveri engine development is an indigenous effort of Gas Turbine Research Establishment (GTRE) for mastering one of the most complex technologies. Altitude Testing and Flying Test Bed trials have been completed which are major milestones in any gas turbine engine development. The other development problems are addressed to make the engine flight worthy through indigenous as well with assistance from a foreign engine house.

Not long back, DRDO was in discussion with Safran (then Snecma) on how to take forward the development of Kaveri with the most advanced technological elements. As per Strategic Affairs Magazine, the negotiations, with the French engine major for co-developing Kaveri engine was however called off in early 2013 after DRDO came to the conclusion that Safran instead agreeing to transfer latest genre engine technology to India had just offered the replacement of Kaveri’s Kabini core with Safran Eco Core which is at the heart of the M-88, the engine which powers the Rafale. Rightly, this was not acceptable to India which was keen on mastering the latest genre engine technologies.

Kaveri engine was originally envisaged to serve as the power plant for the home grown supersonic fighter jet TEJAS Light Combat Aircraft. However, the Kaveri engine program now stands delinked from the TEJAS fighter aircraft project and it is planned to use an upgraded version of Kaveri to meet the needs of the Advanced Medium Combat Aircraft (AMCA) that is now being developed as a follow up to TEJAS by the Bangalore based Aeronautical Development Agency (ADA) of DRDO.

This implies that the Kaveri turbofan should be upgraded to generate 110-kN wet and 75-kN dry thrust. But then an engine of this capability will need to incorporate single crystal blade technology, integrated rotor disk and blades and super alloys of nickel and cobalt. Kaveri engine in its present form uses directionally solidified blade technology which is rather an old hat. The 20-tonne class AMCA designed with stealth features and super cruise capability is planned to be powered by two GTX Kaveri engines. Significantly, the Kaveri engine has been custom built to operate in the demanding Indian environment that ranges from the hot desert to the freezing mountain heights.

New Issues

The noise the five engines specimens make in high throttle regimes is a key issue being placed before France’s Safran for the remaining path to certification. Apart from the noise in the high throttle spectrum, scientists have also been grappling with a flicker, indicating inconsistent combustion or fuel transmission, when the afterburners are engaged. (LiveFistDefence)

On Jan 3 this year, the Safran Group advertised for the new position of Director for the Kaveri engine program. As per LiveFistDefence portal, the good news for the program is that the DRDO has been given a virtual carte blanche to channelize offsets from the Indian Rafale deal to resurrect the Kaveri. Safran, a partner in the Rafale program, builds the Rafale’s twin M-88 turbofan engines. Under the terms of the partnership finalized late last year, Safran is working to modify, certify and integrate the Kaveri on a Light Combat Aircraft air frame before 2020. A later phase in the partnership will involve modifications on the Kaveri for a twin configuration on India’s AMCA fifth generation fighter concept and an altered non-reheat version for the Ghatak UCAV. It is not clear if the Safran partnership will stretch to the concept Manik mini-turbofan being developed for UAVs and cruise missiles.

The Bangalore based GTRE (Gas Turbine Research Establishment) a constituent of DRDO, which is the lead agency for the development of Kaveri, is now hopeful of upgrading the Kaveri engine to meet the needs of AMCA in the context of the vastly improved industrial support base in the country that the Aero engine development program had helped create. The biggest challenge ahead of GTRE would be how to enhance the power of Kaveri without increasing its size and weight and through incorporating the single crystal turbine blade technology. But the reality is that GTRE is now nowhere close to developing single crystal blade technology. However efforts are now on to sharpen the expertise level in the country for developing the high performance nickel and cobalt super alloys for Kaveri.

China on its part is also struggling to develop a reliable turbofan and that country is making all out efforts to realize a range of advanced power plants to propel its military aircraft. The demands placed on an engine of a military aircraft are far more complex and challenging in comparison to the engine of a commercial aircraft. High strength materials and super alloys along with composites are used in the power plants deployed on board combat aircraft so that they can easily withstand high temperature ranges in addition to meeting the needs for speed and manoeuvre. Future fighter aircraft are expected to feature an advanced type of power plant, a variable cycle turbine that can operate in two specific modes-one for higher speed and one for fuel efficiency.

Involvement of Private Aerospace Industries
Bharat Forge

Bharat Forge, Mumbai has developed the Bharat 52, a long range artillery gun developed by the company. The company has extensive experience and core knowledge in — material, material transformation, forging, machining, assembly and sub-systems etc,.

The company has also entered into a joint venture with SAAB for air defense systems and a plant is coming up near Hyderabad. By building the artillery gun, the company has demonstrated its engineering capabilities.

The group is building jet engines, small ones, not as big as those by Rolls-Royce, Safran, GE, P&W and others, for helicopters and unmanned aerial vehicles. The UAV engine are indigenously built. the Chairman has mandated his engineers in Pune that he wants to see the development of the engine in one year.

Apart from this crucial indigenous development the company is also involved in four other procurement programs namely the towed gun, conversion of the 130 mm to 155 mm caliber, ultra-light howitzer, and the mounted gun. Bharat Forge is participating in all the four programs and is sure of winning at least two.

The general agreement is that no Indian company can do everything by itself, there is involvement of electronics, radar, metallurgy and all other kind of advanced technologies which the companies have to master.

The company's strategy is to create building blocks for guns, air defense, Aero engines and components, it is confident that it can make Artillery guns on its own. As far as air defense systems are concerned, it is creating a hub in Hyderabad. In Aero engines, it is making components for Rolls-Royce, Boeing and others.

Poeir Jets Private Limited

Having developed its first jet engine the successful certification of which will put India in the elite group countries that boast of jet engine development.

Poeir Jets Private Limited, an R&D firm under city-based Intech DMLS, has earmarked Rs 20 crore for the project, of which about Rs 9 crore has been spent. Leveraging its rich experience from tie-ups with firms such as HAL and Bharat Forge the company decided to make its own gas turbine engine two years ago.

The engine was fired for the first time on February 8, 2017, and it was a success. Some other tests are going on, and the company is confident that it will be ready to be presented for certification in 18-24 weeks.

The MJE-20 is a gas-turbine engine which can power Unmanned Aerial Vehicles (UAVs) or Remotely Piloted Vehicles (RPVs). Weighing 2.16 kg and providing an uninstalled thrust of 20 kg, the engine will not be able to power UAVs of military grade. But the success has pushed Poeir to develop bigger engines. They have the MJE-40 and MJE-100, which will be able to power bigger UAVs. Given that they are gas turbine engines, they will give longer flying hours.

The firm has there other variant, the SJE-350, which it believes can power bigger planes of strategic importance, weighs 48.36 kg and provides an uninstalled thrust of 350 kgf. However, experts said more thrust would be required to power fighter jets but the SJE-350 in a twin-engine configuration can power a fighter. It was also reported that the company is working on turboshaft technology which will power light to medium weight helicopters.

The Aero engine has been a vital missing link in India’s military aviation. Clearly and apparently, developing and producing Aero engines indigenously could imply a big leap forward for the Indian aerospace sector that would in addition free India from its costly and continued dependence on global engine majors. At any rate, things are certainly looking up for India's indigenous military engine technology development. The mastery of Aero engine technology cannot but be a win-win development for India.
