ADA Tejas (LCA) News and Discussions

Or rather private companies in India should also start investing in engineering research.

They should, but it's not in their interest to invest in R&D with questionable tenders, since they are profit driven! It's easer and more lucrative to do offset work for Boeing, Airbus and Co, than to make heavy investments into a field where they don't see enough returns.

That's because they're looking for short terms returns. Multi billion dollar contracts don't come in a jiffy.
That's why companies like Bharat Forge are awesome - they played the long game & are reaping big benefits.

When DRDO starts developing products, they try to rope in private firms for prototyping etc. The initial orders are small (but at high price), but if the product succeeds then big windfall could be expected.
Most Indian private companies are too shy to participate or take even the slightest risk!!
Bharat Power pack project (to build 1500 hp engines) has been delayed by nearly 5 years because no Indian company wants to participate. Can you imagine the windfall for building couple of thousands of such engines when the product is ready? But they all want to stand by and wait till its ready - and then when the contract goes to an OFB or BDL then they all clamor that private companies are not being given any defense contracts!

Private companies should earn & not expect handouts!

The major capabilities that are yet to be demonstrated on the Tejas are gun firing, air-to-air refuelling and new data-linked software defined radios, among others. The IAF has conveyed that its wants new data links as a standard feature on the FOC variant as communications are an essential feature for an aircraft to operate in a network-centric environment.


..........so and new data linked software is the extra capability which iaf needs in tejas foc.......bdw tejas is going to be a world class........and its taking time

in Us Defence give funding for proof of concept at university level. Then private companies take that proof of concept and build the final product. For aircraft yes private companies build it but funding is still done in part by Defence dept. we need to follow that line.

Yep. DRDO has started doing that too....it's funding a bunch of research in all types of universities.
The FICV program is intended to go the F35 way - fund 2 separate companies to come up with their own design, and then pick the best (which also means that the company will need to develop the design/prototype 'at cost price').

India last year did the policy of funding private companies the reimbursement of development costs and they ended u designing fancy vehicles as IFV and presented it in defexpo!

Private companies only do jugaad but not any R&D. If government funds them wholeheartedly, they will simply remake the existing technology in different shapes and designs, add some music systems and external cameras.

Gun has already been fired on the ground. I am yet to read any issues about it.

As HAL assembles gun on N Number of fighters its not a new area.

Anyway IAF is in no tearing hurry to induct tejas, if we go by the laid back ,one by one new addition of capabilities being asked for by FOC.



All media stories about IAF critically short of fighter squadron as mig21s are falling off the skies everyday ,

That too for just 20 numbers FOC MK1 order.

is not true as far as IAF is concerned.

They are prepared to wait for FOC with more capabilities, as they know it takes time to add them & hv no issues with delays in FOC.

It's their prerogative, so they are taking their own time.

Same story with rafale, they are prepared to wait and add 14 odd new capabilities,rather than rushing in.

Guys who claim delays in tejas has affected IAF Critically can rest assured that IAF is not in dire straits ,

As all these new capabilities asked for by IAF was not in original ASR , so IAF is prepared to wait till new additional capabilities are added to tejas, never mind delayed FOC.

Fr

Read that too, it seems to be a statement of Air Chief Dhanoa, which means IAF is more pessimistic / realistic than ADA.
Given the history it's not surprising, but it's still amazing how they can keep failing the nation that badly.

From 2004 to 2014 it took IAF 10 YEARS to select an MMRCA Winner.

By contrast ADA flight tested tejas for the first time on 2001 & inducted by 2015.

All with close to 3000 flawless test flights & under varying extreme indian conditions. From the himalayan heights of Leg to deserts of Rajasthan.

From day one of operation ,tejas can operate in all indian conditions,
Something never achieved by any imported fighter.

Adding new capabilities like software defined radio, refuelling probe,
New data link etc,etc

That were not present in original ASR,

will only add more time.
Nothing to complain about.

IAF understands that ,

It knows new demands will delay FOC, Doesn't it?

LCA Navy achieves another success

Nice! This is the step I was waiting for.
Now, they'll increase the taxiing speed in steps, till they achieve the carrier landing speed!

HAL to bahut khus hoga aaj.... Tejas's Navy version to be tested from Vikramaditya

 

[Enquirer]

Trishul dude is suggesting that Tejas Mk1A will have Levcons! According to him the flight of Naval version was to complete the Levcon test, so it could be incorporated into Mk1A.

While I have always argued that Levcons should be part of Mk1A, I am not so sure if Levcons could be incorporated into Mk1A in the timeframe (that's left). Trishul guy is known to blow a lot of hot air!.
Levcons will lead to significant changes in the FCS - which was not anticipated in Mk1A!
(unless HAL/ADA have been working away at this for the last 2 years!)

Trishul dude caught once again spewing hot air!
He had said that Naval Tejas was being tested only to evaluate Levcons (that according to him will go onto Mk1A). As is obvious from the live hook test, Naval Tejas is being tested for the purpose of carrier landing operations!

HAL to bahut khus hoga aaj.... Tejas's Navy version to be tested from Vikramaditya

What is the problem of Navy in inducting if its good enough to be tested from carriers?

 

[Flame Thrower]

What is the problem of Navy in inducting if its good enough to be tested from carriers?

Aircraft carriers will be feared only if it's planes carries ASHMs for resonable range.

In current configuration of NLCA, that is not possible.

 

[Enquirer]

What is the problem of Navy in inducting if its good enough to be tested from carriers?

Payload!
NP1 & NP2 will eventually become quite capable of taking off and landing from carriers, but without any significant payload (as the landing gear has become very heavy + the aircraft itself had to be strengthened to withstand the forces + the hook) - primarily because the NP1 & NP2 have F404 and secondly because Mk1 design (on which NP1 & NP2 is based on ) is not the aerodynamically most efficient.
Net-net, Naval Tejas if/when inducted was always supposed to be Mk2 version with more powerful F414; and after having fixed some of the aerodynamic issues.
NP1 & NP2 are still significant milestones that will help Naval Tejas Mk2(if ordered, despite its single engine) or Naval AMCA.

 

[ersakthivel]

What is the difference in operating principles of the two systems mentioned below,


1.DRFM Based ASEA jammers,

2.ASEA radars??


Do both of them operate on the same principle of,

multiple TR Modules emitting different frequency radio waves at the same time to accomplish their mission ??

Or

Both operate on the different principles?



In time a competent ECM For ASEA is bound to emerge is my opinion.



All future developmental versions (mk1,mk2) any fighter uses same or better TWR Engines, to meet future challenges & improve performance.

Has any fighter program introduced a newer engine in their later version, which has a lower TWR than previous??

If tejas mk2 or mk1A has to improve their performance, they need a same or better TWR ENGINES,

Not lower,

I rest my case.

You have just shown your ignorance once again. Go read up & understand the physics behind AESA radars first before making a fool of yourself!
Also, repeating the same nonsense about TWR only cements the notion of you being a moron! Only a moron would care more about engine TWR than the aircraft TWR! You haven't learnt simple math (proportions etc). You had very poor education!

You also had very poor upbringing. You started abusing me & then cried victim and then lied about the whole thing repeatedly.

You got even that wrong and there are 1000s articles and official reports available.

Zero knowledge about anything, that's why I keep saying, read and learn at least the basics. :biggrin2:

It's more than that =>

"The indigenous aircraft carrier is due to be inducted in 2020. I need deck-based jet fighters by then. The LCA Navy is nowhere on the horizon. At present, it cannot be operated from the deck. It still has to go through carrier compatibility trials; it is underpowered; it cannot take off with ordnance. I need a fighter which can operate from an aircraft carrier and is combat-capable," he said.

"It is a good plane to fly, but what I need is a deck-based fighter that is combat- capable"

NLCA is neither available in time for IAC1, nor fits the requirements as a "combat fighter" and that's still generous. There is a reason why all modern carrier fighters are in the medium or heavy class. They provide enough space for large radars, integrated EWs, enough internal and external fuel for long range and endurance missions, enough weaponstations to carry enough fuel and weapons. All this is not possible for a Mig 21 class fighter.

 

[ersakthivel]

Ok

Ok,

With your higher knowledge you can enlighten us,

How many years MMRCA TOOK?

So why the gripe , ADA delayed tejas, if we take first tejas test flight date as datumn.

the truth is both took roughly the same time

 

[ersakthivel]

The radar on tejas is bigger than that of rafale,


If SAAB can be confident about sea gripen,

ADA too can be confident about tejas mk2 naval versions



Even mk1 naval tejas can be used as a cost effective naval trainer.


Load calculations done on naval mk1 will be the emprical data for naval mk2 &AMCA.



&. Which aerospace genius ,defined this epoch making ,"MIG 21 CLASS" ?

I only find light, medium, heavy class fighters in any literature on fighters.

Please give me link , to read
About this MIG 21 Class fighter,

I am all ears to hear that,

Other that one shipwreck called P2Prada , I haven't seen any one using this in a long time in this forum.

He was the only one who repeatedly bluffs that

1. LCA is a mig21 class fighter that doesn't even need multi rack ejectors on pylon.

If he has said the same thing about gripen in any international forum on the net, people would hv laughed their ass off.

Are you the same guy?

Problem with medium class naval MIG 29s are all too obvious to even repeat here.


Naval tejas mk2 is a needed fall back option for at least two of IN carriers , before we see air carriers with steam catapults.

It's more than that =>
