MOD to HAL: Build Tejas Mk.2 With Export In Mind

[CardSharp]

Cost will go down with production orders.

Cost would really go down if you can replace the 40% foreign components.

^^^ We should take inspiration from Chinese on how despite using Russian engines and Russian radars like N001VE from Tikhimirovon J-11s they are able to produce such cheap stuff.

Regarding J-10 ;

According to SibNIA, the J-10 is a melting pot of foreign technology and acquired design methods. “The aircraft is more or less a version of the [Israel Aircraft Industries] Lavi,” say those Russian designers who have worked with the Chinese on this program, “but there are a number of other pieces of other aircraft or technologies that are part of the configuration that they have acquired from different sources.” Those who have observed the process of the J-10’s design also stress that the Chinese not only needed external help in acquiring the building blocks of the aircraft, but they needed assistance to synthesize all the elements they had acquired into a cohesive design.

I dont expect India's first real fighter jet to achieved complete indigenisation.. 60% is actually an achievement in itself.

^^^^^Might be because of the huge numbers(?)

Not a reliable write up!

The author has quoted various experts saying various things and then he has inserted his own make believe figure of 40%.

AFAIK, the engine, ejection seat and a couple of avionics are the only completely imported equipments on board the LCA.


The radar is 50% Indian and the percentage is bound to increase in future!

How do you have a 50% radar? That was the only source I could find. No reliable sources exist that I could find.

The MMR has it's front end and some back end components from LRDE. The rest of the back end is from EL 2032 by Elta.

In software, the Elta code is used for some of the modes only. Rest of the modes are working with Indian source codes integrated with the Elta processor.

That is how I came up with the 50% radar!


It is Indeed difficult to get good info on Tejas and there is lot of misinformation out there. I did find this edition of the Techfocus (a bi monthly publication from DRDO) particularly helpful. You may go through it.

As a sidenote, I would like to add that LRDE has indeed achieved great strides in TR modules for the AESA program.

Successful construction of L and S band TR modules has already been achieved. Emphasis is now on X band for fighter radars. This combined with successful demonstration of GaN technology means that India will bridge the AESA TR module gap with the world by 2015.

However,we are lagging in back end processing and algorithms for some of the radar modes. That is where help is being sought from Elta or EADS (project Uttam). If that deal goes through, it will be a major boost for Indian radar efforts.

Catching up with world might be possible but not in your overly optimistic timeline.

Catching up with America? Not going to happen

There is nothing overly optimistic in my timeline. I've just stated it for the TR modules ( the front end of the AESA).

AFAIK, GaN based arrays are where the world is heading right now, US already there, France by 2012. With the successful demonstration of GaN tech last year, India has indeed taken quite a leap in bridging this gap. (source: DRDO chief's annual address)

As to L and S band TR modules, google LSTAR or Swordfish!

In overall radar tech, US is way ahead of all others and will retain the edge for at least next 15 years, more if their econ stages a recovery!

This is all French to me but I'll trust you to say that there is less than 40% foreign component in the LCA.

Thank you for the confidence in me, bro!

I did go through the major components in the LCA and their origins today. Many of the earlier foreign components are being replaced by Indian made ones. e.g. the MFDs from sextant, RLG based INS, actuators etc.


Here are the major imported systems on Tejas.

GE 404 IN, EL 2032 back end, the helmet-mounted display and sight (HMDS) cueing system by Elbit, Lightening LDP pod and Martin Baker ejection seat.

Also the actuator for auto throttle in the naval version is imported from moog.



Out of a total of 35 major avionics components and line-replaceable units (LRUs), only three involve foreign systems, out of them one will be replaced soon. (MFDs)

Out of this India is working on almost all products except lightening pod. So in the future the percentage of Made in India will greatly increase.

 

[faithfulguy]

Guys, use some common sense. I believe that India should build an airplane that its airforce would induct in a large quantity before it thinks about exporting. Which air force out there would buy something made in India if Indian AF would prefer imports from other countries and only get token quantities from inside India?

 

[tanlixiang28776]

What weapons will India export the Tejas MK2 with?
