looks like they are going to put things on LCA-3 which was planned for MCA for stealth.

re: Stealthy LCA Mk3, AMCA on the cards

so to become a real stealthy combat ac the rcs needs to be around 0.001 but that will mean that the entire body of tejas would have to be made of composite or an extensive(almost total) structural change to the entire fuselage part.do you think its possible in any way given that the current surface composite coverage of tejas is around 90% and the total composite usage is around 45% of the total weight of the ac!:shocked:
I think reporters are merely throwing out articles based on speculations, reducing radar cross section is not an easy task, useing composites alone will not solve the problem as composites are visible at many wave lengths. The current Rafale has some stealth features like angling and when India receives such technology it may be able to incorporate it in LCA. What can be done is reduce RC as much as possible so that the enemy is in range of your radar before he can see you and hence fire the first shot at a longer range and return to base.

If we take cues from the F-15 Silent Eagle we may learn a few tricks on how to make an existing airframe stealthy. However i do not know how they are planning to reduce RC in F-15SE when it has no angles. Either way for complete stealth internal weapons bay is a must and useing conformal bays like on SE we may be able to do something on the LCA Mk-3.

re: Stealthy LCA Mk3, AMCA on the cards

does anyone has got an accurate knowledge about the current rcs of LCA?i read it somewhere that the clean rcs of tejas mk-1 is around 0.6 without the weapons package.is it true or another speculation coz 0.6 is a very small rcs in itself(smaller than the medium class fighters like Eurofighter Thypoon and Rafale)!
You can't place a value on it without knowing a lot of other factors like radar specifications, frequency bands and range.
There is no literature released on it, but what officials have said is the RCS is 3 times smaller than a Mirage-2000. So, if we assume the Mirage-2000 has a RCS of 1.2m[SUP]2[/SUP] from 130-150Km, then LCA will have a RCS of 0.3-0.4m[SUP]2[/SUP] from the same distance when using the same radar and freq band.

so to become a real stealthy combat ac the rcs needs to be around 0.001 but that will mean that the entire body of tejas would have to be made of composite or an extensive(almost total) structural change to the entire fuselage part.do you think its possible in any way given that the current surface composite coverage of tejas is around 90% and the total composite usage is around 45% of the total weight of the ac!:shocked:
Composites have nothing to do with stealth, it is merely a better absorber than metal.

For stealth we need to use materials made of dielectrics or what the Russians are doing with nano-crystals. Shaping, reduction in IR emissions, reduction of unnecessary signals and internal weapons bays are other factors but will be difficult to implement on LCA.

All of LCA's problems are technical. Ministers and babus have nothing to do with the delays. You are blaming the wrong people.

re: Stealthy LCA Mk3, AMCA on the cards

No, thats as wrong as it gets.

Programs run on funds. If funding is not available, and policies are restrictive - eg austerity measures mean less recruitment, programs suffer. Experienced people leave for better opportunities when there is no career growth in terms of better pay as well. Tarmak007 -- A bold blog on Indian defence: CLAW-ING AHEAD: Tejas clan who overcame tech denials turns 20
Tarmak007 -- A bold blog on Indian defence: World-Beaters: The fly-by-wire FCS will take India to new heights (Part-III-B)

Further, programs like the LCA require extensive investment in infrastructure, including quick processing of alternates if the original supplier cites laws and regulations eg MTCR, ITAR and refuses to supply. In India, forget sanction busting, even regular import of basic items goes through kms of red tape and then has to be hit by audit scrutiny. In other words, if you import two of an item from different vendors to cover your bases, CAG will slam you for infructuous expenditure. This sort of red tape rubbish, keeping track of the pennies and losing the pounds entirely (time delay mean imports) is very common.

In India, running your own fiefdom means national goals go for a toss. There has been clearly a serious dearth of vision at the national level.

Take HAL for an example. The company only started investing at any proper level in its own R&D in the 90's. The proposal to develop a FBW system as a tech generation project either using a Jaguar or a Marut airframe went nowhere. Babus at MOD shot down the proposal claiming that since HAL was a manufacturing company, it had no business asking to do such things. Ultimately, by the time the LCA project came along, HAL was in no position to implement it, or even wanted to get into it. So ADA was created. HALs design staff had been virtually eliminated with only a handful of people left, and even juniors in short supply

This is a perfect example of how the babucracy plus short sighted political view stagnated defence.

In this years defence budget, DRDO has got ~70% of their asked for requirement. Saraswat has gone on record stating that the constant underfunding, glib statements about defence preparedness apart, mean that some programs have to be prioritized over others. This means that timelines for some programs extend - in order to reaccomodate timelines to compensate for lack of resources, manpower and hardware (ranging from both design hardware/software to manufacturing systems, to even components required for prototyping).

The level of underfunding of the Indian defence sector can be judged from the fact that many establishments have been implementing PLM software only in recent years, well nigh a decade plus after this stuff became common abroad.

Basically, India has a bunch of generalists - politicians and babus - running roughshod over two groups of domain experts - technology developers and manufacturers, and the users (the services). If they had done an excellent job of coordination, at least this babucracy could be supported. But there is very little overall prioritization at the MOD level which is a bizarre state of affairs.

Take the HAL-LCA case. AM Rajkumar, points out succintly that at least one HAL CEO refused to support the LCA program for whatever reason. Later on, more reports emerged of HAL being more interested in supporting the IJT over the LCA. Finally, there is the case of LCA related projects constantly being sidelined or just treated as "it exists, let it go on". AKM himself ex-HAL notes:
Tarmak007 -- A bold blog on Indian defence: The Iron Bird Team: A Tejas story never told before!

And the first flight happened, the nation applauded it, but nobody hailed Iron Bird team. Dr. B Subba Reddy was transferred to other division for administrative reasons and the program suffered another setback as he was also the deputy director of National Control Law (CLAW) team of Tejas. Some temporary arrangements were done from HAL side to fill the void left by Dr. Reddy, but to no avail. However the core Iron Bird team with the support of ADA was strong enough to deliver the products (the software versions with updates) in time. The HAL saw the Iron Bird team as an unproductive group of people since they were not directly contributing to the production targets of HAL and the approach continues till today. ADA celebrated the milestones of Tejas project with its scientists and between these two approaches, the Iron Bird team was left out unacknowledged at every occasion. The question still remains unanswered: "Whose baby is this Iron Bird, anyway?"
With the project directors of Tejas raising their voices at various forums, the Iron Bird team was finally augmented with HAL manpower in the year 2007 and currently boasts of 18 engineers of various domains. The team is headed by one Mr Sanjay Sharma, who has been associated with Iron Bird testing from the early days. It was his initiative that Iron Bird team still remains capable and efficient despite various setbacks. He also guides a team of 7 highly skilled engineers deputed to National Control Law (CLAW) team of Tejas at NAL. A big section of HAL higher management still remains unaware of the facts, potential, pains and achievements of the team.
This is the sort of thing where somebody at the MOD level needed to have called up HAL, keeping the IAF in the loop, and pointing out that progressing the LCA - even at the cost of the IJT - was a first priority. Importing IJTs - a lower tech aircraft - can be afforded by India. Developing a LCA class aircraft is not an opportunity that can be missed.

Point is this sort of vision is totally missing at the MOD level. The user is not even aware of the fact that it needs to get into program management in a big way to replicate the success of advanced MICs - the MOD wont ask for this either, and in fact may push back. The MOD wont lead overall programs and resource, support them optimally, leading it to the individual agencies to navigate the labyrinthe of the PSU-mix, without having any powers to hold the PSUs accountable either - take the recent BEML case and the way in which its embattled CEO has been going after the exArmy chief despite the number of enquiries against his own self. Then think of what happens when these individuals are asked to pull together for a national program - its ego which rules the day for a few, if not even some gentlemen. And even those few, can cause tremendous damage. A couple of years delay in a program translates to a huge opportunity cost and sours the user as well.

Here is an example of the sort of technology development that is required.
Inside the Agni-5 missile lab - YouTube

See this clip. The first is a clean room assembling the intricate RLG-INS, a huge achievement for India. It takes years of research plus very expensive equipment that can often turn out to be only of limited use (then you have to build custom jigs and assemblies). Only when you are into the 2nd or 3rd product iteration, that do you start making near-optimal decisions. The C-C panel shown in the second part of the clip comes after almost two and a half decades of working on C-C tech. India initially even custom built its own filament machines for the Agni TDS when that was denied by sanctions.

Point is timely funding, overall political support and clear lines of authority, delegation of powers for responsible acquisition (with accountability) are essential not "good to have" for such programs.

The US approach is exactly this, but they lost accountability in their overarching desire for high tech. Incremental innovations are often ignored by them, with every new class often a completely disruptive jump from previous designs - take a look at the Zumwalt class for instance. The costs are ever ballooning and huge, and delays common.

Point is though, for India, this is exactly the same predicament for all of its first programs, since ALL of these programs are often disruptive in nature and do NOT have an existing base to build on. Today HAL is building LAH/WSI-ALH based on the ALH platform, but it had to pay its hidden cost in terms of delays and huge challenges for the ALH itself.

This is basically the thing with Indian programs, because of which the babus and netas have to be 10x more responsive than those in foreign nations where the MIC is already well established. In India, since we are starting from a low industrial base and within the space of two decades wanted to go from near 100% imports to somewhere around 30%, the MIC would have to make its first products on par with the Gen 4 products achieved by other countries and available for export to India.

The challenges involved in such an endeavour completely passed them by. There was no overarching mission or vision. The nuke program for instance was run as a haphazard project with it taking the NDA govt to make the call on tests. They had to do so ASAP befor anyone got wind of it. Which meant the LCA team got stuck abroad with their 1-2 protos of the DFCC in the US, which were promptly confiscated and the team sent back to India. Add a delay of another 2 years. Nobody clearly at the national level kept Kalam etc in the loop about when what needed to occur, before NDA got into power and when this decision would have to be taken & the need to keep a backup in India with everything covered. Basically add a few months to the program ahead, but then avoid taking a hit at the critical path of the project. Way back during PVNR time itself.. the teams should have been told to start backing up such critical programs, even if more funding was required. But such was not done.

Similarly, the actuators were from Moog. The LCA team pulled off an incredible feat by keeping the TDs flying by rotating actuators between the test rigs and the aircraft. This is one of the reasons why so few aircraft were available at the beginning of the program, and shows how it has been run on a shoestring. No other country has done this - - per a test expert from another nation - with whom I crosschecked at a public event. In fact the folks who thought sanctions would kill the LCA as a good lesson for the 1998 tests, were shocked that India managed to develop its own DFCC, and with limited hardware (only a handful of actuator sets and instrumented engines) kept the program running.

Ideally, they should have had excess actuators to spare, and also enough funding to develop a parallel program with a completely independent source like Russia. We never did.

Such penny pinching, at all levels, may result in a "cost effective aircraft", but it causes huge issues at every level of the program - reducing development time and risk, take a backseat. There is no vision about developing such strategic projects and hence letting funding flow!
In contrast, imports at 3x the cost, citing operational urgency are common.

While babus and politicians can point to the state of the economy as a reason for some of these things, in many others - they squarely take the blame for not fostering a properly resourced and enabled program. When Kargil happened VK Malik was asked by a MOD babu - as to why he wanted more weapons, didn;t the Army have enough rifles already? Malik replied that the Army ran on more weapons than just rifles.

If this is the knowledge level amongst many of our bureaucrats, that says it all.

The NSG head in Black Thunder pointed out he received a message from another such gent, saying - why the delay, just go in and sort them out no, take a few casualties, its ok.. this is the attitude which leads to fiascos like the no of CRPF folks killed in Operation Green Hunt etc.

Theres a lot our babus and politicians could do better

DRDO Chief Takes A Spin In A Gripen



The DRDO chief's sortie has less to do with the MMRCA competition and more, perhaps, to do with Saab's own interest in engaging with the DRDO in a variety of programmes, presumably the Tejas Mk.2, unmanned air vehicles (including UCAVs) and others.

Somehow, considering where the indigenous fighter programme is right now, it might have been a more impactful photo-op if Dr Saraswat had chosen to make his fighter debut in the Tejas Mk.1 trainer. The Gripen and Tejas are variously compared too. Who knows, maybe he'll do it now.

Stratpost editor Saurabh Joshi was at the flightline during the DRDO chief's flight and took these photos he's been kind enough to share with me.

Tejas jets display firepower in pokhran


Pokhran, which witnessed the celebration of India's nuclear might, is now witnessing a different scene: Made-in-India Tejas fighter jets are demonstrating their fire power here.

Three of these military jets have been taking off from forward Air Force bases to pound the area with a variety of armaments-from precision guided bombs to conventional bombs weighing up to 500 kg.
These exercises constitute the most important phase ahead of their formal induction by the Indian Air Force and are intended to ensure that the bombs are released and hit targets on the ground with accuracy. The IAF will acquire 40 of these fighters with the first squadron set to be positioned in Tamil Nadu.

Tejas MK-2 will fly in 2015

Tejas MK-2 will fly in 2015

Sources close to lca-tejas.org , have informed that Work on first air frame of Mark-2 variant of Tejas fighter aircraft , will start soon and aircraft will be ready for its first flight by 2015 . we have been also been informed that first Naval LCA MK-2 will also be ready at same time which has been dubbed has NP-3 , while NP-1 which is based on MK-1 design characters just had it first flight in month of April this year and another LCA NP-2 which will be a Single seat variant will also be ready by year end , both Naval LCA aircraft's will then be transferred and will be based in Goa Shore based testing facility some time in 2013 onwards .

Mark-2 will be powered by more powerful GE F414-IN6 with 98 kN of thrust and refined aerodynamics, and already have placed orders for 99 in first batch and second batch will be ordered once Tejas MK-2 and Naval LCA MK-2 clears first flight . The IAF is committed to procuring an initial 83 Tejas Mk2s and the Indian Navy has expressed its firm requirement for 46 LCA Mk2 (Navy).

LSP-8 and SP-1 will also have it first flight by end of this year and SP-2 will have first flight in 2013 , and it likely that LSP-7 and LSP-8 , along with SP-1 and SP-2 will be handed over to Indian air force for user trails by mid of 2013 . Navy will also order some MK-1 , which might be used as Induction fighters for pilot training , before moving to LCA MK-2 .

So Mk-2 varients of both IAF and Naval version will be ready at the same time, i.e around 2015 .... :thumb:

Tejas aircraft in final trials at Pokhran

The current trial of Tejas in Chandan, Pokhran firing ranges of Jaisalmer district, is part of the final operational trials (FOC) and will continue for two days. The Tejas is planned to be cleared for operational service by late mid 2013. The light combat aircraft design and development programme is being led by the Aeronautical Development Agency (ADA) of the department of defence with Hindustan Aeronautics Limited (HAL) as the prime industrial contractor.

"Three of these Tejas aircraft have been taking off from forward Air Force bases to pound on an area with a variety of armaments - from precision guided bombs to conventional bombs weighing up to 500 kg during the tests. These exercises constitute the most important phase ahead of the aircraft's formal induction by the Indian Air Force and are intended to ensure that the bombs are released and hit targets on the ground with accuracy," an official source said. Teams of specialists from DRDO and HAL have already reached the firing range to conduct those tests.

"The IAF officially accepted its first Tejas fighter on March 21, 2011. The Tejas is planned to be cleared for operational service by this year end. The initial weapon tests including bombing begun at Pokhran firing range last year. Tejas' final operational clearance has reportedly been delayed till mid-2013 or later," defence spokesperson Col S D Goswami said.

"Tejas is a major modern Light combat aircraft that have been contracted for induction into IAF.The cost of procurement of the Tejas light combat aircraft is about Rs 8,861 crore. The design and manufacture of modern combat aircraft involves development of very high and sophisticated technology skills. HAL is manufacturing the light combat aircraft for IAF," he added.

This is the HS-748 test bed. It was also the one used in AIRAWAT project that got cancelled because of the crash.

CSIO's HUD for N-Tejas to be tested in July

The head-up display (HUD) for the naval version of the Tejas light combat aircraft is scheduled to be flight-tested next month. The naval version of the aircraft had undertaken its maiden test flight on April 27.

The HUD is an opto-electronic gadget installed above the cockpit's instrument panel that superimposes vital flight parameters on the pilot's vision of the outside world, giving him all requisite information at a glance and without having him to peer down inside the cockpit, thus enabling him to fly with his "head up". Air speed, altitude, weapon status, rate of turn and angle of attack are among parameters displayed on the HUD.

Prototypes of the HUD's naval version have been fabricated by the Central Scientific Instruments Organisation (CSIO) here and one unit is being integrated into the naval fighter's cockpit by the Aeronautical Development Agency (ADA).

A team of scientists from the CSIO are in Bangalore for the purpose.

The HUD for the naval version is a further development of the HUD produced for the air force version of the Tejas. The air force version has already been integrated into the cockpit and several units have been installed in the Tejas' prototype and limited series production aircraft.

The HUD for the naval version is technologically more advanced and has different technical specifications than the air force version and the operating parameters, cockpit configuration and the pilot's field of vision are different.

The naval version is also designed to withstand the impact of harder landings on the aircraft carrier's deck vis-a-vis landing on runways.

The CSIO has transferred the technology to the Bharat Electronics Limited (BEL) for commercial production of the air force version of the HUD. The Panchkula unit of the BEL has produced about 45 such units. In addition, two HUD units have also been fabricated by the CSIO for the HJT-36 trainer developed by the Hindustan Aeronautics Limited (HAL) and a project is underway to develop an HUD for the HAL's intermediate jet trainer.

Tejas completes weapon trials at Pokhran Ranges

IOC-2 completion likely by year end

By Anantha Krishnan M
Express News Service
Bangalore: Three platforms of India's Light Combat Aircraft Tejas successfully completed advanced armament trials at Pokhran Ranges. Military sources confirm to Express that this time the focus of the trials was locked on to specific modes of releasing various weapons. The current campaign saw Tejas testing various altitude and speed combinations of 'critical nature.'
"During the just-concluded weapon trials at the forward areas of Pokhran Ranges, practice, dumb and live bombs were released. A laser-guided bomb (LGB) was also tested. The trials are important as the platform is now being tested for its conversion as a fighting machine from a successful flying platform," sources said.
Different trials of sensors included testing of radio-altimeters, baro altitude, radars and laser. "Tejas' limited series production (LSP) variants LSP-2, LSP-3 and LSP-5 are part of the current campaign. All modes of weapon releases and all types of sensors were tested at various points in flight envelope. The campaign team is now heading for sea trials," sources said. The Tejas variants flew at speeds between 900-1000 KMPH during the weapon trials, logging in total of 25 flights. In September 2011, Tejas had conducted weapon trials in Chandan and Pokhran Ranges, looked into accurate positions and target parameters.
With all the platforms put together, the Tejas programme has to its credit 1903 flights, cloaking 1120 hours, so far. Its makers in Bangalore will have to catch up with the lost time in the programme, especially after its Initial Operational Clearance (IOC-1) held in January 2011. "Currently we are looking into the major segments of IOC-2. We are hopeful of completing the IOC-2 parameters by the last quarter of this year," sources said.
