I don't think French media or anything from a French pov can be trusted.wait what m88 kaveri ??? means safranised kaveri not refined one???
The source does not mention dry thrust which is a very important parameter and MTOW of plane depends of dry thrust.Yes, but China can't afford full scale TOT either. No one in this world can.
Russia gave 100% ToT for Al31F engines to India. Russia may also have given ToT for WS13 and WS10 engines which were replicas of RD93 and Al31F engines respectively.Yes, but China can't afford full scale TOT either. No one in this world can.
Hey @Vijyes !! Long time no see!!Russia gave 100% ToT for Al31F engines to India. Russia may also have given ToT for WS13 and WS10 engines which were replicas of RD93 and Al31F engines respectively.
I used to visit but not comment for some time.Hey @Vijyes !! Long time no see!!
BTW, what is 100%ToT?
I doubt that. You mean that even all Titanium parts are made in India? From raw-materials? I don't think that is possible. Yet.100% ToT means that every single item is made from raw materials by India for Al31F engine in HAL Koraput. This includes blades, turbines and every nut and bolt.
Kaveri jet engine ready to be signed.
Decayed performance at high altitude, insufficient thrust, excessive weight. Some of the problems the DRDO has reported on its Kaveri turbofan engine, a project in development for nearly three decades. It has now emerged that an unexpected ‘noise’ during high power trials has all but stalled the programme in what the team believes is its last mile. Detailed analyses over the last two years have failed to narrow down the nature of cause of the noise, and scientists are also unable to tell if the noise is an influence aerodynamic performance. What Livefist can confirm is that the phenomenon is only the latest in a series of complications that have bedeviled the Kaveri. The noise the five engines specimens make in high throttle regimes is a key issue being placed before France’s Snecma 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 is engaged.
On Jan 3 this year, the Safran Group created and advertised for the new position of Director for the Kaveri engine programme.
The good news for the programme is that the DRDO has been given a virtual carte blanche to channelise offsets from the Indian Rafale deal to resurrect the Kaveri. Snecma, a partner in the Rafale programme, builds the Rafale’s twin M88 turbofan engines. Under the terms of the partnership finalised late last year, Snecma is working to modify, certify and integrate the Kaveri on a Light Combat Aircraft airframe 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 Snecma partnership will stretch to the concept Manik mini-turbofan being developed for UAVs and cruise missiles. One of the Kaveri specimens was on display at the recent Aero India show.
There are important implications of the Snecma-DRDO partnership on the Kaveri engine. A Kaveri engine sporting potential commonality with the Snecma M88 could be compelling factor in how India chooses its next fighter jets, both for the Indian Air Force and Indian Navy. Those implications, at any rate, would be clearer only once the Kaveri proves itself at every level of performance and envelope. It’s useful to break down the state of play with the new Kaveri in the projected mix.
LCA Mk.1/1A: Currently powered by GE 404. Intended to be powered by modified DRDO/Snecma Kaveri, with first integration aimed for by 2020.
Rafale: Powered by twin Snecma M88 turbofans.
LCA Mk.2: Two of eight GE F414-INS6 turbofan engines were delivered last month to keep the programme rolling. The future of the Mk.2, though, remains uncertain. If the modified DRDO/Snecma Kaveri can be uprated enough to meet Mk.2 demands, it could change things. For the moment, this doesn’t appear to be on the cards.
IAF Single-Engine Fighter: Either the GE F414 (on the Gripen E) or the GE F110/Pratt&Whitney F100 (on the F-16).
Indian Navy Multirole Carrier Fighter: A toss-up, effectively, between the Snecma M88 and GE F414.
AMCA: Intended to be powered by modified DRDO/Snecma Kaveri in twin engine configuration. But this remains in the air for the moment. There are other suitors, notably Boeing’s aggressive pitch that pushes the enhanced GE F414 supercruise capable engine for the AMCA, an engine family that Boeing’s Super Hornet shares with the Saab Gripen E.
GHATAK UCAV: DRDO/Snecma Kaveri modified for non-reheat stealth operations. The Government is clear at this stage that it doesn’t want a foreign powerplant on the sensitive programme.

Russia doesn't give out its SCB technology, no one does.Russia gave 100% ToT for Al31F engines to India. Russia may also have given ToT for WS13 and WS10 engines which were replicas of RD93 and Al31F engines respectively.
Yes, titanium machining is quite easy. There is nothing much about it. It may take a slightly longer time than other metals but still, the technique is similar.I doubt that. You mean that even all Titanium parts are made in India? From raw-materials? I don't think that is possible. Yet.
That is not technology but raw material. Yes, the raw material may have to be imported. However, it is a part of the contract and is only enforced by trust. India can get raw material on its own too as and when needed as technology is in Indian handsI know that vanadium billets had to be imported at an astronomical cost from Russia under the terms of the agreement so while they said we could build we had to use their raw materials
Russia is technically an ally of India. Russia did give technology for making RD33, RD25 engines for MiG21. India had made over 600 MiG 21 in 1970s-1980s completely in India. Russia also gave cryogenic engine to India for space launch vehicle for reverse engineering.Russia doesn't give out its SCB technology, no one does.
Air Chief of Marshal Arup Raha, Chief of Air Staff, emphasised the need to ensure that Koraput emerges as aero engine capital of India. Speaking at the Golden Jubilee Celebrations of HAL Koraput Division at Sunabeda (Odisha) today, the Air Chief pointed out that the Division has the potential which is evident from the work done in the past 50 years especially in carrying out manufacturing, repairing and overhauling of MiG and Su-30 engines. He declared open a two-day national seminar on “Emerging trends in aero-engine architecture and self-reliance”. The Air Chief also inaugurated the indigenization and out-sourcing exhibition organized on the occasion.
Speaking on the occasion, Mr. G.C. Pati, Chief Secretary to the Government of Odisha described the Golden Jubilee of HAL Koraput as the momentous occasion for the state. He also appreciated the contribution made by HAL in the development of the region, especially on the CSR front. He said HAL should lay more emphasis on outsourcing since such a step would lead to creation of jobs and businesses at different levels in the state.
Dr. R.K. Tyagi, Chairman HAL while thanking IAF and the state government for their continued support, called upon the large gathering of HAL employees to achieve more in next 10 years than what they accomplished in the last 50 years. “Koraput is already aero engine capital of India. In general HAL is on the right path with its all-round progress especially in the last two years. We have come a long way from being manufacturing company to a technology driven company”, he said.
Dr. K. Tamilamani, Director General, (Aeronautics), DRDO in his speech insisted that efforts must be made to have indigenous engine as dependence on others costs the country heavily. “Since we have the potential and infrastructure as companies like HAL are around, we must make all the efforts with proper time line”, he said.
Mr. S. Subrahmanyan, Managing Director of HAL MiG (Complex) in his welcome address outlined the growth and contribution of the Division. Mr. Maloy De, General Manager (Koraput Division) proposed a vote of thanks.
A coffee table book on 50 years of Koraput Division was released on the occasion.
The two-day seminar focuses on topics such as advanced gas turbine engine for combat aircraft, developments in fourth and fifth generation engines, aero-engine applications in the context of advanced magnesium alloys, technology challenges in developing aero-engines etc. Scientists and experts from all over the country are participating in the seminar.
About HAL Koraput:
HAL Koraput Division, was set up in April 1964 at Sunabeda, Koraput District of Odisha to manufacture R11-F2 Turbo-Jet Aero-Engines for MiG-21Aircraft. Since then, the Division has manufactured & overhauled R-25, R-29b, RD-33 and AL-31FP engines to power the MiG-21Series, MiG-27M, MiG-29 and Su-30 MKI aircrafts respectively for the Indian Air Force. During the last 50 years of glorious service, the Division has manufactured 1574 engines and overhauled 7417 engines.
The Division presently has state of the art facilities for manufacturing 4th generation aero engines, which include, Robotized TIG Welding (Manned Chamber Welding), Electron Beam Welding, Detonation Coating, Hot Isostatic Pressing (HIP), Isothermal Forming, Cold Rolling of Blades, Ion Nitriding, Alphatization and a battery of CNC machining centers. The Division has also mastered critical technologies for manufacturing Single Crystal Blades and Directionally Solidified Blade castings.
The Division is presently augmenting its capacities for manufacturing and overhauling enhanced numbers of AL-31FP engines, Overhaul of RD-33MK engines. The Division is in the process of establishing manufacturing facilities for AL-55I engines for the Intermediate Jet Trainer aircraft and the High Altitude Test Bed facility.
The Division has achieved a Turnover of around Rs.1750 Crores during the financial year 2013-14 with a dedicated workforce of 3775 employees, comprising of 2945 workmen and 830 executives.
HAL being a responsible corporate citizen, strives for the inclusive growth of the people living in the surrounding areas. Towards this, the Division has adopted 14 villages around its vicinity. The Division provides free medical treatment (indoor/outdoor) to the residents of the adopted villages. Further, infrastructure like school buildings, community hall, open / bore wells and solar street lighting were established in the adopted villages. The Division also provides skill development training to the youth. The Division has established HAL-SAI Sports academy to train the local talent in archery and football, which has gained prominence at the state and the national level
Sire, the French will "invest" money as part of offset. Its not donation. If they invest, it means a partnership, which means a joint project and sharing IP rights. It will definitely need an agreement that will need to be negotiated.Technically, why would India be signing anything about Kaveri?
Kaveri is Indian engine, and as per the requirement of Offset for the 36 planes, the French opted to provide help for Kaveri engine in lieu of the Offset, so in a way the IP should belong to India, so what deal are we we to sign? The French want to buy some Kaveri engines for their Rafales?
If you are capable of making all the spare parts for MKI then why do you keep running out of parts?Russia is technically an ally of India. Russia did give technology for making RD33, RD25 engines for MiG21. India had made over 600 MiG 21 in 1970s-1980s completely in India. Russia also gave cryogenic engine to India for space launch vehicle for reverse engineering.
I am not sure if Al31F has SCB or has directionally solidified blades. It may be that Al41F has SCB while Al31F does not? Also, you are forgetting that the real reason for the strength is not just SCB but also Rhenium metal. I am not sure if India had rhenium access. The metal is too scarce.
The point here is that Kaveri is fully Indian engine with complete Indian manufacturing. India does not need money from France to make Kaveri. Also, France is incapable of using M88 core as the size of M88 is 27.5x139 inch diameter and length respectively whereas for Kaveri the dimensions are 35x154 inch. That is a serious size difference. So, unless you are suggesting that France will develop a new engine, it is meaningless to ask for French investment. If France develops a new engine for India, then the time taken will be 10-12 years. I have also pointed out several times that India is capable of making Al31F completely in India from raw material stage and the notion that India lacks blisk technology or metallurgy is absurd in the above post:Sire, the French will "invest" money as part of offset. Its not donation. If they invest, it means a partnership, which means a joint project and sharing IP rights. It will definitely need an agreement that will need to be negotiated.
Yes, titanium machining is quite easy. There is nothing much about it. It may take a slightly longer time than other metals but still, the technique is similar.
Let me show you blisk manufacturing:

Anyways, here is the official HAL statement that they already have SCB technology:

India has all the critical technology for MKI as ToT from Russia but there is a contractual obligation to buy some spares from Russian OEM. This is just as a symbol of trust towards Russia.If you are capable of making all the spare parts for MKI then why do you keep running out of parts?
No technology transfer in the Su-30 spare parts deal
