Re: LCA News and Discussions
Wow, I have to question your expertise here, because you are belching absolute nonsense without half decent info.
Possibly you could answer about why does the material guy in Midhani today has to worry about MK1 drag?

Re: LCA News and Discussions
I don't understand ... why we are so low on self esteem? How you can learn from single iteration of LCA project to reduce drag and weight issues? There are too many sub-systems which are used first time. First and most important is make a system working and then do the fine tuning and performance analysis.
As far as LCA-MK2, is concerned it has more powerful engine which should compensate for weight and drag. And in the mean time if everything is working OK in real conditions, then they can think of further improvements in a couple of sub-system at a time. So chill and enjoy that LCA MK1 development is closing, although it might be having some minor or few major issues. Which will be handled with LCA-MK2.
Trust IAF has enough experience in maturing a newly system e.g. like they did with Su-30 MKI.

Re: LCA News and Discussions
That itself provides a good insight.your really think that simply going to the next project without solving the problems is the right way?
Not too sure where to start. Let us try ................
Yes weight issues, which translates into drag at some point in time. However, these weight issues are NOT design related. They are material related problems. They used to be distribution related problem - as in proper management of real estate within the LCA - which got resolved (by rearranging the innards).When you look at Indias military aircraft projects and the reports about them, the issues of design are ore then obvious, be it LCA, LCH, Saras, IJT, all of them are facing weight and/or drag issues
You see India is not a leader in material sciences (MS) (and will not be for some decades). IF India had access to really good R&D in MS she would have had a decent chance to resolve such issue.
The second issue is related to testing - as stated above. One may have great designs, materials, sensors, etc, but if you do not have good test data you are starting from square one. You see there are no shortcuts here and dhekha jayega. IF you do not know the risk is huge - and one India is not willing to take - rightfully so. India cannot take. She would rather wait till the tests are right than to take a risk.
As far as I have heard the LCA is a near perfect aircraft - so the design has to be OK. My impression was that the MK2 was taking care of the weight related issues. No?
BTW, if the design is an issue, what do you expect a design team to do at this stage of the game? Redesign the MK1? Just curious.
Like which ones?even then, there would be several other projects, where they are needed before starting AMCA.
Also BTW, how much do you know about the AMCA?
__________________________________________
A few years ago I had suggested that the LCA be shelved after calling it a tech demo and take on the MCA (as it was called that then) seriously. I still think for a "LCA" (yes, the real one) to take shape it will take at least 2-3 iterations AFTER the MK2. I feel that the LCA is one of the best things to have happened in India. But, I also feel that with undue pressure it will never reach it full potential in EVERY respect. India I feel is mature in many respects - design being one - but has a way to go in many areas.
India needs an aircraft that is free of everything - politics, IAF pressure, etc. LCA should be that one. Make it, break it, learn from it, rebuild it, ........... only way out. Failures are a necessary part of this development cycle.
Re: LCA News and Discussions
all said and done, if a/cs don't enter services, then we have no feedback for development.
Re: LCA News and Discussions
Then we will have no positive feed back from IAF which is like IA only interested to forin mal with % for all and sundry. We need to force things on the people who are not keen on having "Indian" products. Otherwise I fear LCA is already becoming like an other Arjun.

They don't want any geometry changes, only improved EM performance. If possible better lightning protection and better smoothness.
Info nugget: IFF dipoles are integrated into the MMR antenna. I used to think that they were the two silvery things above the nose, in front of the cockpit. (like in the F16).
P.S. Corrected formatting

At yesterday's roll-out of the 500th Super Hornet/Growler, Boeing program vice-president Kory Mathews confirmed that the F414 Enhanced Performance Engine would be the baseline for the company's offer to India.
...
The new engine offers up to a 20 percent thrust boost. That would take the EPE up to 26,500 pounds of thrust, giving it the best thrust/weight ratio of any fighter engine -- almost 11:1. Alternatively (an option understood to be attracting interest at Saab) the EPE could be delivered with a 10 percent uprate and very generous temperature margins, extending its life and reducing fighter life-cycle costs.
The EPE "will not make much difference at an air show", says Boeing chief test pilot Ric Traven, but dramatically improves the fighter's performance at high speed and altitude, halving supersonic acceleration times. For the Gripen, the extra thrust would translate into further-improved supercruise (supersonic level flight without afterburner) capability.
Re: LCA News and Discussions
With a 11:1 thrust/weight ratio what is the probability of the LCA Mk 2 achieving super-cruise capability at altitude ?
Re: LCA News and Discussions
we made a big mistake not choosing to partner with EJ200 rather Snecma... ideally, it would have been better if had GE 414 techs for colloboration.. but, we still have no idea what are the exact details of snecma deal, as the last interview with dr. saraswat only talked about deriving at what thrust requirements are needed based on the platforms they are trying to use.
standardarizing on F-414 platform would have solved many problems.. but we have no idea as to what was unkill politics.. and what is surprising is there was a screw driver tech transfer for 414 as well for mk-2. so, ideally, it would have been better with either GE or EJ200 which have already proven for near 100kN or greater than that thrusts.
snecma has long way to go to even near 90kN wet.

Re: LCA News and Discussions
Dude, clearly you are confused about how product design & development works. At any given time, you don't just work on todays tech, you also work on tomorrows and the requirement gathering for even a generation after that. It doesn't matter if today's program is in progress and is facing challenges, if you don't start working on tomorrow's program now, you will lose the time advantage of starting the program earlier.Sancho wrote:...Repetitive stuff snipped...
As stated earlier, their work is only done, when the design issues have been solved (MK1 drag, MK2 just entered design stage, with still a lot of work to be done during the prototype stage) and even then, there would be several other projects, where they are needed before starting AMCA.
When you look at Indias military aircraft projects and the reports about them, the issues of design are ore then obvious, be it LCA, LCH, Saras, IJT, all of them are facing weight and/or drag issues and your really think that simply going to the next project without solving the problems is the right way?
Different groups of people are often allocated to these programs, and detailed design and development is not required at the same level for the in development one, and the in planning one either.
That's how it happens.
So while the LCA certification and product improvement process is "ON", simultaneously, parallel teams have to work on the AMCA as well, finetuning it in the process. Otherwise by the time the LCA is done, to start the AMCA will take up several years of requirements gathering, definition, back & forth specification decisions, budgetary allocation fixing etc worth of effort. The whole supply chain extending back to development partners need to begin this process as well, not just the folks at ADA.
Right now is the perfect time to get this exercise done So that by the time the LCA MK2 is developed and production ready, the base groundwork for the AMCA is laid out, basics are in place and the manpower can then shift to the detailed D&D phase for at least the TD/Prototypes, with the FSED to follow.
Re: LCA News and Discussions
I think biggest benefit of Mk2 will be 1m longer fuselage giving it the right tapering shape to reduce drag and the EPE engine. might also increase the volume of any fuel tanks near wing root or inside the wing.
Re: LCA News and Discussions
Singha-> quite frankly when will get the 414 epe engine, when will the LCA MK-II protytpes fly and God only knows when it will induscted in IAF. I feel the problems with LCA are not purely techical , but the arms agent lobby in Delhi which does not want this as a threat to its income. People like SUresh Kalmadi have passed resolution's in parliment to kill the project.
Re: LCA News and Discussions
At the time that we were searching for partners only Snecma and Saturn were ready to give us what we wanted. P&W wanted the IPR. Dont think the EJ200 was on offer at that time. Ofcourse no deal has been signed yet but I think the Snecma deal is tied up but the Frenchies are holding it to ransom linked to the Rafale deal.SaiK wrote:we made a big mistake not choosing to partner with EJ200 rather Snecma....
Re: LCA News and Discussions
Depends on which of the aircrafts we are talking, take LCH for example, the first design turned out to be too heavy and draggy as well, pylons, tail and air intakes needed to be re-designed.NRao wrote:Yes weight issues, which translates into drag at some point in time. However, these weight issues are NOT design related.
Wrt LCA, overweight is an issue according to initial plans, but compared to other fighters in it's class, even LCA MK1 is pretty light and offers a good TWR too. So when it still has performance issues, what else than the design is the reason?
I hope so, but they are actually increasing the weight by far, because of the changes that we know so far (streched fuselage, new internal fuel tanks, new engines and other systems), but it will be interessting to see what else will be changed.NRao wrote:My impression was that the MK2 was taking care of the weight related issues. No?
As stated, find out the problems and fix it for MK2, instead of simply going over to the next project. My problem is, that we have very poor planning and that we don't really finish our projects, before we already start to dream about others. We celebrate any baby step like the roll out of another prototype, while not a single fighter is in operational service yet, or would be useful to serve our forces and the security needs of India.NRao wrote:BTW, if the design is an issue, what do you expect a design team to do at this stage of the game? Redesign the MK1? Just curious.
As mentioned in my earlier post, LCA MK2, FGFA, armed Rustom, AURA UCAV, because all these aircrafts are meant to be in service earlier than AMCA and because they add more advantages to IAF too. The only field where AMCA really would be needed is, as a carrier fighter, because IN don't have a 5th. gen option, other than F35 so far. But then we have to develop it for the navy in first place and not only navalise a fighter developed for IAF.NRao wrote:Like which ones?
I feel the same, that's why I want our officials to keep focusing on it and not beeing distracted from newer and shinier projects, without really finishing LCA. We need a reliable, cost-effective low end fighter that soon can be inducted to IAF, not dreams about a stealthy LCA MK3 or AMCA in 10 to 15 years.NRao wrote:I feel that the LCA is one of the best things to have happened in India.
On the other side, we don't need a "modest" (like IN itself describes N-LCA) carrier fighter in the short term, because we will have more capable Migs anyway. A naval AMCA in the long term would be more important and why anything beyond a N-LCA tech demonstrator currently is a waste of resources.
Re: LCA News and Discussions
Depends if there was ever an offer to partner with us on Kaveri, becaus so far that was reported only by the French and Russians.SaiK wrote:we made a big mistake not choosing to partner with EJ200 rather Snecma...
Please read the post above, because I don't have an issue with working on NG developments in general, but that we don't finish our projects and that more important projects than AMCA should be done earlier!Karan M wrote: Dude, clearly you are confused about how product design & development works. At any given time, you don't just work on todays tech, you also work on tomorrows
AMCA now comes only because the delays and failures during the LCA development and not LCA was successfully inducted and is soon to be completed.
Where?Karan M wrote:basics are in place
- do we have knowledge in stealth design?
- do we have developed at least any multi mode fighter radar yet?
- do we have a working engine that could be used for AMCA, or at least a prototype?
- NG avionics, weapon systems?
Not really and that's why our contribution to FGFA is very limited as well. We still don't know which radar LCA MK1 will use, let alone MK2, the Kaveri co-development is still not fixed and the first use was meant to be an upgrade to LCA MK1. So when there is still so much to do to get a real base in our industry and with improving, why bother with AMCA at this point?
Re: LCA News and Discussions
Good news from livefist
Tejas Mk.2 Build Begins
Tejas Mk.2 Build Begins
Finally, HAL has begun the process to build the first Tejas Mk.2 air force prototype, envisioned as a slightly larger but much more capable fighter than the floundering Tejas Mk.1. On November 19, HAL's Aircraft Research & Design Centre (ARDC) floated the first of many requirements for raw materials -- alloys and such -- for the first Tejas Mk.2 (first pictures) prototype vehicle and other assemblies. More requirements will be put out over the next few weeks.
HAL is looking to put the Mk.2, powered by the General Electric F414-GE-INS6 turbofan engine, into the air in 2014. The highly anticipated Mk.2 programme will cost at least $542.44-million (Rs 2431.55-crore), comprising full scale engineering development. The IAF has put down an official requirement for 83 of the Mk.2s. Working on a detailed post on the Mk.2. No timeframe, though!
Re: LCA News and Discussions
yes definitely resources need to be devoted to give the Mk1 full spectrum A2G and A2A capability and its radar & avionics brought upto the mark. these things if left hanging now "dekh lenge yaar" will bite our ass again in the mk2.
astra mk1 is another black hole project, our hopes and queries go in and nothing comes out as news its a vital gap in our portfolio as also a IIR AAM which isnt even in the plans. sudarshan is supposed to be ready yet there is no news of confirmed orders.
and surely the kaveri snecma unless its a super secret ATV type help obtained from Rus is dead in the water, with 3 yrs gone and no official contract even signed, let alone any work done. we better get in line for the 414 EPE and hope Indo-US relations are sustainably good.

Re: LCA News and Discussions
my understanding is the following from MK.2 perspective
Thus a missing critical technology
Don;t get me wrong or too pessimistic it is just based on the open source information of the last 15 years and more. So one of the
option is to get all the critical tech as part of Rafale and Pak Fa deal . These deals should only be seen from the perspective of the kind of tech. they provide, nothing more nothing less
I have serious doubt with the radar part [AESA i mean] at least not before > 2018 since i don;t see a prototype or some test bed for its testing.Singha wrote:A2G and A2A capability and its radar & avionics brought upto the mark

LCA reminds me of the judgement - Sau kilo Pyaaj ya sau kode.
One of the difficulties with trying to play off one player against the other is that a third player can you by the balls.

Re: LCA News and Discussions
the pgm has definitely lost momentum and perhaps managerial interest in the last 1 yr.
Re: LCA News and Discussions
LinkSources have told idrw.org that Tejas MK-II will carry many of the 5th generation technology; advance variant of this will later find its way into AMCA, first Tejas MK-II aircraft according to sources will be ready by end of 2013 or early 2014 and will have its first flight in end of 2014 .
Work on Design aspect of Tejas MK-II is complete and F414-GE-INS6 engine will power the Mk II version, Tejas MK-II is one meter longer then Tejas MK-I , and will have a stretched nose and larger section behind cockpit for incorporating avionics components. Aircraft will be able to carry 1000 kg more on the external stores more than current 4000 kg carried by Tejas MK-I.
Both articles point towards 2014 , Hope they show some urgency
Re: LCA News and Discussions
It said at the end of 2014 so we can safely assume, considering Track record, mid of 2015. After that, possibly by 2017 MkII will go for production that is well before the deadline given by GoI to DRDO for LCA.
Finger crossed.

Re: LCA News and Discussions
if there is anything to believe the timeline projections, it has be something that is with production engineering after execution of couple of squadrons. before that, it is all guess and paper notes on schedules, just to please babooze plans.
of course the momentum is lost.. and it is a well known fact. i think, we should know that and look at the program not as a project management issue, but the project itself. heck, we did not care about project management and deadlines.. ever, so why bring in that. those discussions we had earlier on PM issues, shall remain for a long time to come. we have no process engineering happening, so expect that to continue.

Re: LCA News and Discussions
I think it all depends how fast aircraft is rolled out and how fast aircraft starts doing taxi trials , 6 months delay in roll out and 6 months delay in first flight is respectable but hope they don't mess up and delay both by a year .

Sir the issue is not with MK.2 aircraft structure/ framework or it flying [thanks to GE 414] , that is very much possible sometime in 2015/16 like the Chines are flying J 20/31.nash wrote:It said at the end of 2014 so we can safely assume, considering Track record, mid of 2015.

Finger crossed.
But a cutting edge fighter aircraft is a combination of lot more.
The point is we did not take much time to move from ALH to LCH, since we had the building blocks available[indigenous/sourced], similarly from Agni 3 to Agni 5.
So if we want to think of AMCA or MK.2 with 5th gen tech , then we require some building blocks for it which can be adapted to our requirement and here comes the critical requirement of a quality AESA and reliable , high performance engine.
If we don;t have either then we may again land up in the same situation where we have a flying aircraft which may be GOOD, but would be compared to something like a JF 17 and not even a Gripen NG or for that matter an F-16 block 60/70 and i am not even counting the typhoons and rafales.
Re: LCA News and Discussions
and the problem is the zoo of eastern and western eqpt we use has its own issues
= EL2032 _+ desi maal => Rus wont play ball on R77, we are forced into Derby..and neither is US interested in letting anyone integrate the AIM20C7 into non-american radars barring the EF and Gripen.
= Astra mk1 is in "stealth mode", with no known IOC date or flight test reports, it may even have been quietly canned
unless we have a good fighter radar , a good BVR aam and a good IIR AAM, things will be tough.
everyone wants their pound of flesh and boxes us into corners.

Re: LCA News and Discussions
we have knowledge and experience of req. gathering, design and development of Fighter Aircraft like LCA, thanks to painful and hard-work of our scientists and technician.But we don't have any prior experience of testing and that too without taking much risk.That's why we are taking so much time to get clearance and make LCA operational.
Good thing is because of knowledge in other stages of product development we can move dedicated resource for MkII.
In product development you need to do many things simultaneously and have option and space for "what if?", and i hope DRDO have it.

Like in my others posts i have always mentioned that if i stand corrected for any of my posts i will be the first to welcome it
What i only suggest is that with the kind of tech that is currently available i don;t see a cutting edge 5th gen AMCA in the near or mid term.
An advanced 5th gen AMCA or for that matter LCA Mk.2 with 5th gen tech requires at least a radar similar to AN/APG-81 , an engine which is at least as advanced as EJ 200 and avionics better than spectra.
Do we have them or can we realistically develop them in the next 10 year

I think Mk2 is only 0.5 meter longer and 0.2 taller with same wing span....

Perhaps the LCA Mk.1 development is complete and they are taking the next logical step.GeorgeWelch wrote:Perhaps an indication that they're abandoning LCA to go all-in on Mk.2?
Re: LCA News and Discussions
quite a huge space when one consider just keeping it for extra fuel.. cause, F414 is a larger game plan for the IAF, and they want more power and quicker turns at higher Gs.Katare wrote:I think Mk2 is only 0.5 meter longer and 0.2 taller with same wing span....
but then again, it all depends on who is sitting behind the drawing board. there is always another way to do it... the best option is always seen after a design takes shape.
let us see how the livefist guy reports [cause he seems to be the first person ever doing such exposure to public]

Re: LCA News and Discussions
That is what I know. Also the idrw article speaks of 1T extra payload on the pylons, I had not heard of that either (though it is entirely feasible).Katare wrote:I think Mk2 is only 0.5 meter longer and 0.2 taller with same wing span....
Or may be they had hit a roadblock, which they fixed and they are back to flying. Who knows .GeorgeWelch wrote:Perhaps an indication that they're abandoning LCA to go all-in on Mk.2?suryag wrote:the thing that i feared the most

I don't think that they would abandon the Mk1. They have 40+ GE-404 engines to use. Mk-1 is very valuable, it is the stepping stone to success. They are ironing out so many things on this plane. All these lessons are important for the LCA MkII and AMCA. It is important to operationalize Mk-1 and further iron out the wrinkles.
