Re: LCA: News & Discussions: 15 August 2017
Wow, the F136 idiocy has really caught the fancy over here. It's an engine that's huge for an F-16 sized fighter, hell it is 1.5 times the thrust of the engine in f-16. Do people even stop and think before they blurt out their random thoughts ?

No no Eric Saar I didn't mean together on one platform.
But to choose between both whichever has Faster Surge, how does one knows? Is there a UNIT for that?
I m Sorry I couldn't articulate the question properly.

The idea was to have a TejasXL same design Tailless Cranked Delta on the lines of F16XL.
Since GE's f136 is anyway going to be wasted. One hand washes the other.
A bomb truck with lots of Pylons:
Imagine TejasXL carrying 16 Garuthma+ Spice bombs. Raining them on enemies.
Re: LCA: News & Discussions: 15 August 2017
Does anyone think this is even possible in under 15 years timeframe? Or that airframes are scalable? Everyone is targeting 2030s for AMCA despite close to 10 years of groundwork. That's the reality and I think people should take their flights of fancy into design your own fighter thread.
Re: LCA: News & Discussions: 15 August 2017
believe me, I do know the backstory.NRao wrote:well RM,
The "2-engine LCA" and teh picture you posted WAS the MCA, which morphed into a totally diff beast called the AMCA. They are NOT the same...regarding 2-engine LCA, AMCA
I shared that image because at one time MCA was supposed to be just an enlarged LCA with 2 engines. I want AMCA to go back to that philosophy for its Mk1, except for form factor i.e fuselage design, in order to gain radar deflection & internal weapons carriage.
*everything else* should be based upon existing tech, most of which would be flying on LCA. if you think that makes it obsolete it simply means that the LCA itself is obsolete, if we take a subsystem by subsystem view.
so, which LCA subsystem(s) do you think no longer meets the requirement of a modern AF ?
Re: LCA: News & Discussions: 15 August 2017
Saar - customer (s) have to agree. It will obviously get benchmarked against jsf a d the likes
Re: LCA: News & Discussions: 15 August 2017
Pandyan,
If a two engine MCA is as capable as a Rafale in 20 years (at MLU), it should be good enough. That is a consistent standard. (My conjecture is that Rafale MLU will be as expensive or more expensive than a new MCA Mk 0.5)

Re: LCA: News & Discussions: 15 August 2017
Admiral Sir, with due respect I would argue that this focus from mk1 -> mk1a -> mk2 does not truly take into consideration the Navy's requirement. Its a model that will work for the IAF, but even here one could argue that the Mk2 is redundant because tthe mk1a is set to provide most of the mk2's usp. So whatt is the point of developing a fighter suuch as the gripen NG, which has taken over 10 years already and is struggling withh weight issues? Again, it will likely not work for the navy and second, most of its functionalityy will be provided by the mk1a.Rakesh wrote:Cain-ji: Let's come back to earth Focus on completing Mk.1 production, move on to Mk.1A production and then on to completion of development of Mk2 and commence production. Leave the twin engine to AMCA.
It is a futile exercise in insanity, repeating the same thing over and over again expecting different results.
Might be far better to consider an intermediate fighter between the mk1a and amca that is very close to the lca in design but does not suffer from the lack of space which necessitates lengthy and painful development times. Instead go bigger - we already have everything that is needed to make it a product with faster time to market - expertise in design, materials, control laws, sensors, avionics and testing. We may even have the engines. An LCA mk2 should essentially be an amca mk.0 witth decent shaping (planform alignment and s shaped ducts but no internal carriage), 11+hps some of which might even be recessed to provide low drag and rcs along with possible supersonic cruise, aesa, irst?, composite structures, Basicallly on par/betteer than any eurocannard, su-35 or super hornet. 10 - 11 tons empty and 18 tons max thrust. This is doable in the next 10 years imho. The Navy will jump on it and the AF too.
Re: LCA: News & Discussions: 15 August 2017
That's exactly the point of discussion. That this engine is dead for USA but has lot of value therefore we should co develop with GE a& RR for projects 20 year down the line.ks_sachin wrote:Gyan, brar-w in a previous post has categorically stated that the F136 is dead.Gyan wrote:LCA MK3 with F136 engine will also address the size and range issues of Navy.

Well you dont waste your time talking any thing technical when you meet such people perhaps the only time you would meet in your life and he was with his better half , So conversation was general and photo click with him to remember , He was very happy and excited about Tejas progress and saw great prospect for the Bird in the IAF coming from his mouth was satisfaction enoughKaran M wrote:Lucky you!

Re: LCA: News & Discussions: 15 August 2017
We have seen all the engines through this discussion now - F414, EJ200, F110, AL31, 117S, F136. Wait until Izdeliye-30 is available (if at all). We will try to put that on future LCA or AMCA too.Thakur_B wrote:Wow, the F136 idiocy has really caught the fancy over here.

Re: LCA: News & Discussions: 15 August 2017
AV, great job tracking this! Good question on LSP 4 as well. We had IFR, Gsh23, BVR, Supersonic tank on the short list.
Guess would be that the gun is being tested along with associated vibration tests for LRUs. BVR + Radome performance on another?
Key data points by Tejas LCA -- Flying Daggers will have 7 birds by Dec 2017. SP5 will be ready soon. So SP7 will be ready soon as well!
Tail nos for LSPs are being masked.Could someone explain the intent or rationale? (Is it because each LSP has a specific feature being tested and we do not want to share info or progress?)

btw, I was mistaken in my previous post -- if LCA admin says the squadron will have 7 by this year end, it means they are expecting 4 in the next three months. Could you please confirm or enlighten?
Re: LCA: News & Discussions: 15 August 2017
IAF has SP1-3 with them for sure, SP-4 in all probability has already been handed over a couple of months ago and perhaps SP6 has also joined or about to. SP5 is expected soon to come out of assembly line.Marten wrote:Ah! I figured tail nos with LA are already in the public domain. (SP3 == LA001 and so on).Kakarat wrote:

Re: LCA: News & Discussions: 15 August 2017
x-posting from Misisles dhaga:
From the news:A Sharma wrote:Indian Air Force likely to start trials of Astra missile from today
This series of tests are particularly aimed at testing the seeker of the missile. The seeker provides the missile guidance as it tracks and locates targets. The seeker being tested is a newly developed indigenous system. It is being tested for the second time, defence officials said.
“At least eight trials have been planned in this series and if weather permits, the tests would start from Thursday,” the official informed and added that the missile would be fired in a war-like situation.
Last year, the IAF had cleared limited series production of the missile and decided to obtain at least 50 missiles to gauge its performance before giving bulk order for its all fighter aircraft.
The missile tested during last December had successfully demonstrated its aerodynamic characteristics, repeatability, robustness and endurance capability. The IAF and the DRDO are also working on integrating the missile on light combat aircraft Tejas.
Re: LCA: News & Discussions: 15 August 2017
I hope with the Work done on NAG IIR seeker can be used for AAM purposes also next. Our pilots not having a need to converse their AAM's Drop Tanks ordinance etc can be very useful in war. Reading write ups on 1965-71 wars it was noted that components like drop tanks had to be conserved since there was not more than 1 or 2 drop tanks per fighter.

They are opening the envelop with the Derby missile and automatic slow speed recovery, both of which are going very well.

just re-size the LCA to accept 2 engines (F-414 if that's all we have) and re-use whatever subsystems you can from LCA.
forget all unobtainium tech, at most stealthy form factor and internal hardpoints. that's what the original MCA was

AMCA is coming in two variants a stealthy version with no external hard points, and a semi stealthy with external ordinance.
So part of what is being wished for is already being planned. I cannot post a link as I do not remember where I read it.

What why have 2 separate versions for a single aircraft. Why not have a single version like the f 35 that has external hard points.

Will tell you how the matriarchal Nair tharavadus used to be run in malloostan. The 'karanavar' (eldest male member) runs the show, keeps all the keys etc, while the women actually owns everything. The "measuring of paddy" is a big ritual, where the 'karanavar' opens the big 'paththaayam' (rice silo) and measures out the rice to meet the expenses. The evil ones used to always trim down the 'allowances' making the women folk to 'make do' with the reduced amount, often resulting in them half starving. I heard this first hand from my mother, who went through this herself.
I am told that ALL the programmes of MK1A/MK2/AMCA were starved out in the past months. I heard from the chaiwala that 'approval' apparently come for some of the programmes, but we are still waiting for it to trickle down for the bid process to restart.
And BTW, the bid process is a friggin tamasha. The budget is always less than the money required. The timeline is always less than what it takes (with solid late delivery penalty which is 10% now), and the spec is never finalized, so that you can ask for freebie extras to what you build.

Though the correct reason for the slowdown is accurately described by Swaminathan Iyer here http://blogs.timesofindia.indiatimes.co ... -slowdown/
Our outgoing Defence minister in his Finance Minister capacity has curtailed spending until clarity emerges on which fighter program to pursue.
The Rafale was an exorbitant bad purchase for a meagre few fighters, however NM pushed for the deal to show his proactiveness on defence modernisation vis-a-vis stagnant MMS & AKA.
I've always maintained India has money for a single fighter program after Su-30 completes production in 2020 and the decision timeline is now.
Remains to be seen if Nirmala Seetharaman chooses Tejas or F-16.
