:twisted:

Please stay on topic.

That means :
a> No comparison with aircraft A,B or C.

For short-and medium-range air defence, the bulk aircraft is obviously the home-made Tejas Mk-1A and Tejas Mk-II.

Equipped with an Active Electronically Scanned Array radar they will, like Rafale, be 4.5 generation, but more agile and cheaper to buy and upkeep, and seed a sustainable Indian aerospace industry. In a single combat a Rafale can beat the Tejas, but a Tejas swarm can down a bunch of Rafales anytime; meaning quantity will prevail when the qualitative difference is marginal.


BK needs to know more about Tejas qualitatively I guess. We have to analyze from RCS values.

=======================================


If you ever Visited Aero India in last decade or so there are high chances that you might have seen witnessed a sterling Tejas demonstration flight performed by this man . if you are lucky enough you might have also had brief opportunity to catch up with Group Captain (R) Suneet Krishna who is also known has Mr. LCA by supporters of the LCA-Tejas program.

Group Captain (R) Suneet Krishna is only Test Pilot who has been flying various Tejas Aircrafts for more than a decade now and officially joined ADA in 2001 was piloting Chase Mirage-2000 aircraft, when first LCA Prototype TD-1 made its first flight.

I was lucky enough to interact with Suneet Krishna few times while I visited Aero India, he can literally demolish any arguments put forward by any Anti-LCA brigade and calm serious questions posed by supporters of the LCA-Tejas program.

Recent Barrage of Anti-LCA reports by Indian and International media just after IAF agreed to accept to place larger orders for LCA Tejas in its current configuration needs to be countered and Why this Man needs to speak now to Silence its critics.

Group Captain (R) Suneet Krishna as a Test Pilot in Indian Air Force literally has flown every single type of aircraft operated by IAF and have been credited with more than 5000 hours on more than 40 aircrafts types.

Group Captain (R) Suneet Krishna was first LCA-Tejas Test Pilot who achieved Critical milestones like 100,200,300 Hours on various LCA Variants. Suneet also has been credited for providing many valuable inputs to make Tejas a completely pilot-friendly fighter by bringing out many modifications to the Tejas? cockpit over the years.

He is also credited with many key aspects of LCA-Tejas program like in its flight envelope expansions, in improving fly-by-wire system, expanding Angle of Attack (AOA) and also in integration and testing of Various weapons systems and avionics .

In few questioned posed by me, he Said LCA is comparable to current contemporary aircrafts and is an evolving platform which will meet all future needs of air force too. He also had high praise for American engine saying that 404 is good enough in many ways and is not has thirsty has some Russian engines and is quite fuel efficient leading to the better range for the aircraft. he also had high praise for ADA engineers who had carried out perfect Engine integration on the aircraft to get best out of the engine and also compared handling characters of LCA-Tejas with Mirage-2000s, another single-engine, delta wing aircraft and said LCA-Tejas had better handling.

With LCA-Tejas Program entering critical production phase soon, we might see rise in Lifafa Journalism where our National Paid Media might go on an offensive in attacking LCA-Tejas Program on behalf of Arms Import lobby and why people like Group Captain (R) Suneet Krishna and few of other Test Pilots associated with LCA-Tejas Program can help stop rumor mongering on performance of LCA-Tejas .

When they are retired they can, but as long as they are in the forces they can't speak what's on their mind unless approved by higher ups first. Even then, there are restrictions on what they can say. Promotions are stake and outliers are more often than not weeded out.

Air Chief Marshal Arup Raha in this recently held Press Conference indirectly confirmed that Airforce is no longer interested in MK-II Program and might walk away from the project and instead support India's 5th Generation AMCA fighter aircraft program.

For long Defence Analyst had linked MK-II Program requirements to Indian Navy which wanted a Single-engined equipped Tejas to have higher thrust class of jet engine so that it could allow aircraft to carry a decent payload from an aircraft carrier at sea which IAF saw has an opportunity to demand better performance aircraft then in its current configuration.

Speaking to ADA engineer in Aero India earlier this year it was confirmed that MK-2 contrary to popular beliefs will not address larger operational radius but will only improve on better performance and better indigenisation and Better Cockpit layout and Avionics.

The redesigned airframe of single engined Tejas MK-2 will be developed on parallel to AMCA which will see mating of 110kN engine with the first Prototype by the end of 2019 as planned by DRDO and ADA. HAL was hell bent and strongly opposed development of the MK-2 project and Questioned need raised by IAF since many of the key demands asked by airforce could be made available in MK-1 airframe itself which will allow HAL to get more orders and streamline production of Tejas MK-1.

Sources close to idrw.org have informed that Airforce has not walked out of MK-2 project and it is pretty much onboard it, but will be reviewing MK-1A project where HAL has promised to remove technical deficiencies of MK-1 and also agreed to introduce 4 key requirements like new Aesa Radar, IFR, EW Suite and New BVR missiles while reducing its over engineered components while maintaining safety aspect which will lead to reduction of overhaul weight of the aircraft and also improve its maintainability.

Airforce will soon take a Call on the MK-2 program in a year or two after much deliberation with all Concerned parties and after review of MK-1A said same source and Developers too will decide which Variant of MK-2 (Naval or Airforce ) will be built first depending on user interest. Indian Navy is only one who has committed requirements of 56 aircrafts from MK-2 Project and IAF had earlier committed 86 aircrafts which might be reviewed after the performance of MK-1A aircraft is gauged by air force after its first flight in 2017.

Recent plans of Airforce to place larger orders for MK-1/MK-1A will allow breathing space for MK-2 developers which will allow them to explore possibilities of incorporating technologies from ongoing development research work on 5th generation fighter jet programs like AMCA and FGFA leading to better performance Tejas aircrafts which will keep it technological relevant platform post 2030 before AMCA Production takes over

http://idrw.org/questions-on-status-quo ... more-76188


no.. bad idea.. tranche based development model is best to progress the LCA platform. Raha ji does not have experience in building expertise on LCA nor as a user who is also a stakeholder like USAF with Raptors.. we need to have that Mk2 to move into AMCA. Mk2 is an important step to graduate.. after all, nothing is magic without proper v&v.

After Mk1(a), then there would be another huge gap for AMCA.. and another mother of all MMRCA contract deals will follow up. IAF should never shunt any intermediate versions towards AMCA platform.

THIS WOULD BE A BIG MISTAKE AGAIN!!

But the Navy needs its mk2 jets, so the programme will go on. I suspect the Air force will ask for some mk2 sqds later to fill numbers.

What happens beyond 120 LCA Mk.1/A is anyone's guess at this point. Maybe the IAF knows but it's holding that close to its chest.

Do not think this is posted earlier- did check it unless I missed.

Cross posted from Rossi thread by NRao
viewtopic.php?p=1919046#p1919046

Defence Analyst Ranesh Rajan believes that Parrikar seems to have made up his mind to support Indian indigenous programmes to fix long term Indian Air force woes of depleting fighter aircraft jets, rather than going for short term purchase of aircrafts from abroad. Rajan also added that as per his sources Parrikar was the force behind MK-1A project who brought all stakeholders in the same platform and sorted out mistrust and convinced IAF to support Indigenous projects.

Big “No” for India Air forces repeated request to expand Current Rafale fighter jets order from 36 to 80 came from Parrikar who was not convinced that Procurement of only Rafale jets will be the only saviour for India or Airforce ,he reportedly asked to neither consider ordering small batch of additional Sukhois or go for Tejas in larger numbers informed Defence Analyst Ranesh Rajan. ( likely typo must be either and not neither)


Focus is clearly on Indigenous projects and purchase of fighter jets from aboard has been under greater scrutiny due to lack of funds withing government and FGFA programme might be another Project which might be ready to be axed said, Rajan .

^if it is MoD / Parrikar directive, and understandably and logically well done, it should be effectively communicated to our chiefs. It is not good to take pot shot at each other (gov and the forces) on this subject matter, as the objective of both is the same. it is important they call each other and not to go public without having an understanding.

otoh, if LCA tejas need some history making.. let them join the bombing parade in Syria. make it so! we have to convey the world where we stand against ISIS as well.

We do not need to join fight against ISIL. May be do something in Afghan war. But those are the decisions normally taken after examining lot of inputs and aspects. It will not be some advertisement work.

LCA or no LCA, we have no need to get involved in some stoopide war somewhere. I used to be totally mystified at the way the stoopide ISIS were being projected as soopermen, laying waste to everything they came across but now the mystery has been solved and any body can whoop their raghead asses.

Suddenly, the stoopide, sly Indian media has no more India targeted rabid propaganda tales of the ISIS invincibility and their savagery, trying to make out by guileful suggestion that the end of the world has come and all hot headed long suffering, ill treated mard folks are running off to join the ragheads and implying that the day of reckoning for yindoos had come and how the yindoos would be decimated like sheep to the ISIS slaughter.

some one should now take out that baghdadi b@s@#$%&^ in his turkish hospital bed along with his US made bedpan. maybe the ruskis will oblige??

Defense import lobbies are in high gear after Mr. Parrikar's recent saboteur actions. Even they are lost with to publish next using presstitudes as every action by European lobbies are getting countered by Russian all the while loosing focus on LCA.

Lately they seems to have regrouped and focused solely on LCA, and its getting more and more amusing with next article.

Expect some sabotage too, as was done during Arjun trials when it neared induction.

The way things are unfolding it would seem the IAF will continue to remain a force with many types of combat aircraft. Many types but small quantities of each.

IMO, in an imperfect world the IAF should focus on what they have (or will have domestically soon) by continuing to induct Su-30MKI and LCA Mk.1/1A/2 in larger numbers over the next 10/15-years. Build enough domestic capacity to induct equivalent of 2 to 3 squadrons (something like 2 LCA and 1 MKI) every year. Double down by getting the best upgrade packages for both of them and acquiring force multiplers to increase their effectiveness. Continue to retire obsolete fighters or at least move them to reserves for their last legs. With this kind of approach by 2030, the IAF would have 20 MKI squadrons and 20 LCA squadrons. Legacy types (MiG-21, MiG-27, MiG-29, Mirage-2000 and Jaguar) would be all retired or serving as reserves.

Post 2030, any excess Su-30MKIs and LCAs could be put into second-line reserves if induction of new types AMCA or FGFA supplants them in the active squadrons after reaching the desired number of squadrons. There are no second-line reserves currently and to me that is a very big gaping hole during wartime.

I think a modi visit to Team LCA and especially HAL production team, and give them a good earful would be a nice beginning. They have to giddy up as there are ton of indigenous efforts at stake!~ IAF would not be averse to go doosra on LCA anytime when things go south either on production or capability. They have ton of international maals flashing cards at them every second. The latest one being boeing super bug... adding to the usual noise from vishnu som's swede friends.

Also, we should not rely on GEF404IN->414 orders. The initial bunch is fine, but we have to get Team Kaveri get their dose of steroid shots and revamped team/structure/funds.

If the khabar about US jumla is true on any scale, then what else pointers needed for MoD/DRDO?
Even if the news is half truth, it is worth an investment to bring back Kaveri program 110-135kN walas. I hope that 3D printing news (ref: kaveri dhaaga) is true as well.

regardless of the thrust status, if Kaveri did deliver 80kN, then it must get inside one TD/LSP to check it out and get live data!

India's recent request for uprated Flatbed GE engine to power AMCA is still at doldrums even when Ge was logical choice to power Tejas MK-1 and MK-2 till no Transfer of technology was involved, moment India requested TOT from Ge for the Uprated Engine which will be funded by India, United states already has started backtracking even when India has Cleaner track records in respecting Intellectual property rights and have successfully licensed Manufactured modern jet engine like Russian RD-33 and AL-31 without making any illegal copies of it .

While India wants to seriously work with Unites states on development of key defence equipment which can help our armed forces in maintaining balance in the region but there already have been to many instances of Us policy flip-flops to suggest that the United States is still not ready to move away from current Buyer-seller relationship into more strategic partnership which involves joint development and sharing of defence technology. with Obama entering its last phase of his presidency, India should not expect anything out of ordinary from Us anytime soon and for time being should stick with traditional defence partners like Russia and Israel.

well, a well directed and timely article.. and they (Gov, Mod, public-private enterprise) are listening, working and slowly taking the shape.
Shifting Dynamics Of Indian Aerospace Sector

Aequs Aerospace SEZ set up in 2009 as India’s first fully operational aerospace SEZ with a thrust on precision manufacturing has covered much ground in giving a practical shape to the Make in India initiative of the Indian Prime Minister Narendra Modi by acquiring new capabilities through joint ventures.

Aequs Aerospace created a new milestone in high precision aerospace forging by commissioning a 10,000-tonne capacity hydraulic forging press in 2014 ... Interestingly, while developing the Kaveri power plant meant to propel India’s fourth generation fighter aircraft Tejas, Bangalore based Gas Turbine Research Establishment (GTRE) had to look beyond the borders of India for the kind of metallic forgings that Aequs is now capable of delivering.

Thanks SaiK, Dornier-228 is already license manufactured by HAL, so TASL is building aero-structures for the NG version I guess.

Haa...I am so happy to have read this. I hope its true and it would teach GoI some lesson and stop them from begging anymore and start putting some serious money in Kaveri development. We are 15 years from AMCA production, which is long enough for us to get our act together and come up with 110kN engine of our own. We can use EJ200 for prototypes of AMCA or our own Kaveri-90kN class engines if we can manage to make it flight worthy in next 8-10 years which is again possible.

While requirement for developing jet engine rests on its own merit, by linking development of an engine and the plane, you're making the same mistake as was done in case of LCA. So much was planned to be developed de novo for LCA and that too so far ahead of country's scientific base that we ended up with serious issues. For once, just imagine if GE-404 was not available. We went for large %age usage of carbon composite not factoring into account that a third party can literally hold you by b@lls on such 'non-lethal' component.

By all means, develop a domestic engine, but don't peg it to AMCA. That's recipe for disaster. Fly the a/c as soon as possible like T-50. IAF needs 200+ AMCA....make the first few squadrons fly with whatever you get...own engine can come with later batched.

For countries like India who are building combat aircraft but don't have indigenous jet engines (or acquired full capability to develop new variants of existing ones as yet), a pragmatic approach is to have an imported "proven" engine that matches desired specs for initial test and production variants while a parallel effort goes on for R&D of a local engine of that specification. When that local engine bears fruit, it should be made use of in future variants or possibly at MLU (a fighter in its 30-year life will go through around 3 engines). Even for the primary imported engine, you need to have secondary import option as a standby in case of sanctions or other restrictions that may come about.

That was a little jingoistic. :mrgreen: But I do feel this should be our Plan A. We do not have to peg it to a/c project time lines. We can always have a plan B for de-risking project. A timely review of situation will make sure that plan B will take effect if plan A fails.

We can have target specifications of Kaveri-110 similar to F414/EJ200 in matching class and design AMCA for that specs, such that we can easily replace the engines with minimal efforts. This is doable. Today we have a working engine at hand and a working aircraft. We are no more doing ab initio development of new engine and new aircraft from scratch, even if a lot of technologies are new, we can de-risk them easily, unlike in 1990s. We can test a lot of technologies on LCA MK2 test-bed. For Kaveri-110, we can de-risk a lot of technology by building Kaveri-90kN and putting them on some of the LCAs. In fact i feel its essential to make production version of Kaveri-90kN if we ever want to make Kaveri-110kN for AMCA in time.

Today we can take parallel paths which was not possible in 1980s/90s since we were empty handed back then. I feel we can do Kaveri-110 in 15 years given adequate resources.

have we been able to mate a kaveri with a twin engine jet like SU-30 or MiG-29 yet. Last heard, no spare airframes were available for GTRE to play around with. Hopefully not just 1 but a few can be made available for this venture.

The issue is simple. We will have some 100 of LCA MK 1 with the old GE engine (Total needing 300 engines, 3 per air frame). That engine it looks like is being discontinued (do not know what it means, meaning no improvement or no manufacturing after initial Indian order). If all GTRE can do is in next 5-10 years, come with exact replacement engine of this we would have achieved much!!

Vishnu, thanks for the ack! :D

The GE engines will be the choice until we have zero dependency.. and that does not seem likely to happen anytime soon (a decade plan?). Unkill's strategy is engage pakis with a nuke carrot and to get an additional memory-foam layer on their existing bed... we have to measure the outcomes from their strategic desires and game plans. It would be oxymoronic relationship without having to do anything with India.. anything to keep India tied down with a 'well arranged set of exceptions and controls', scoped and within strategic target.

On the Kaveri thrusts, it would be wise to consider de-rated specs with some adjustments to future IAF challenges and growth needs. The EJ200s were designed for growth with tweaks. Similar design must be taken so that with the same design, we can plan +/-20% additional thrust needs.

Example: if K 110kN is approved, the design must validate for 88kN<K>132kN. I know this would be Herculean task for our designers, but it is not impossible. GE, PW and Eurojets do this. The EJ version also has a 30% growth projected design. If it was a fist full of $ more for the EJs, it is worth to look their designs to begin with.[not necessarily TOT, but do it by first principles].

Yagnasri, I was just saying it.. why not? even LCA can go on bombing raid against the maoists too. Anything to be on the books should be welcomed. some precision strikes to begin with at bastar. :)

Only if you have billions to burn, that kinda money would be better invested in our infrstructure and public health institutions than blowing it on middle eastern or afghan tribals

Trust me, the U.S. Has already recouped its money from the first Gulf War ;) ... you don't fight just any war; you fight "profitable" ones like in the Middle East where you can get cheap oil as a victor.

Profitability is the lowest of measures when it comes to security. It would be ranked so low even in the QoS trade-off list in deciding platforms and designs when it comes to something like LCA where it can be tailored, tweaked, programmed, integrated and measured exactly for IAF requirements. It is all in the hands of IAF how to take this baby to even a Raptor Jr configuration [tranches and blocks].

I distinctly remember a company called Taneja Aerospace, with some tie-up with Parventia( sp) an Italian aerospace company. Are they involved at all in defense manufacturing, or concentrating exclusively in the civil aviation sector, or even hobbyist one. Then there was a Bashi Aerospace and a Sparr in Bangalore doing some fairly sophisticated stuff. Haven't heard from any of these three of late!

Their airfield south of B'lore is where the UAVs get made and tested.

But is the GE-404IN is still being manufactured? We have all this plan for projected LCA numbers, do we even know if that engine still has a production line?

The engines will be GE-404IN. We have just enough to make the first 40. IAF has to quickly firm up the orders for the Mk1/Mk1A, so that orders for the next 80 can be placed immediately.

Meanwhile the fleet which was grounded lately due to landing gear issues will get back in the air from next week, says the admin of LCA-Tejas FB page. He also confirmed,
The tandem bombs will be tested soon and they are part of air to ground weapons meant for LCA.
The mark 1A will be free from all prevailing maintenance issues and the AESA radar plus the EW Suite will be integrated. The integration process has already been started.

Good info. BTW which AESA LCA will have? Is Uttam ready for use or it will be ELTA-2052??

Also Indranil, I don't think we will see LEVCON on AF version. They have been working with it since long time, at least since ~ 1995, (oldest reference to LEVCON I have seen in one of the ADA publications). They have had enough time to consider it thoroughly for AF version it seems. If LEVCON was really so effective for improvement of the performance parameters, particularly the one which LCA is always said to be falling short on - STR, it should have been put on the AF version by now.
