The Air Force has already placed orders for 123 LCA fighters and HAL is targeting a gap of 200 fighters that the Air Force will face in coming years.
NEW DELHI: In what would break new ground, India has started work on developing an unmanned combat version of the home-grown light combat aircraft (LCA), with a task group being constituted to study how to convert the fighter for a futuristic role.

A team has already started work on the project to convert the LCA into a drone and India’s premier aircraft manufacturer Hindustan Aeronautics Limited (HAL) is confident that the project can be carried out within a short time frame.

“We have started an internal study on making a unmanned combat aerial vehicle (UCAV) on the Tejas platform. Besides, we are confident on coming up with an unmanned version of Chetak helicopter as well,” HAL Chief T Suvarna Raju told ET.

An unmanned version of the LCA could be used for cross-border strikes — missions that place a high risk on pilots in case of a ditching in enemy territory. India is also working on a project named AURA to make a futuristic combat drone that would be powered by a modified version of the Kaveri engine.

The drone, however, is several years away as the project is still at the design stage. While unmanned LCA would be no match for a futuristic stealth drone, officials pointed that out converting a flying platform into an autonomous unit could be faster and cheaper short term option.

Yes, Argentinian, Romanian and heck even Indians were taken by the Israeli for a ride. A 'jugaard' was shoved down their throats. They should have listened to those lectures. People in IAF and HAL should concentrate on attending the lectures rather than arranging flower pots during Aero-India shows. Isn't it?

Poor Jha, he doesn't get to attend lectures these days

These DRDO guys, I say you, are a lazy lot. They don't attend lectures. Specially Aero-India lectures.

Youre going the wrong the line again,those radars as i have explained are modified to fit on another aircraft and in all aircraft you cried are smaller than the base varaint. Try also find out how much the others took to fit the same radar on diff platforms,ofcourse rant and cry and fantasy world doesnt change the fact....

You yourself proving the incompetency of yours in understanding what others are saying and your not willing to listen.....Check the video from AI2019 by Anantha Krishnan on the uttam aesa radar where he clearly says the radar is designed keeping tejas in mind specifically ....Also go through the Lrde VIDEO IN AI2017 on Uttam AESA where he explains the shape of the front end,why it is been adopted and this radar fits better on lca than anyother radar....

Rest everything is your mental creation. Those aren't my creation.

 

[Steven Rogers]

Oh you aren't author/ co-author of any those papers? Contributor may be?

I have a general question for you. What is a 'solution' and 'optimum solution'? What is 'trade-off'?

And what is 'juggad' called in English?
And why should I fit APG 81 into F16?

Correct, I must listen to them, those lectures. You must be a regular listener. But, your posting quality is taken into account, I am skeptical, whether it makes any difference?

However, the very thought of fitting any radar to any airframe gave birth to what you called 'no brainer' 'juggad' and 'any radar' ( EL/M 2052) was fitted into 'any aircraft' ( Kfir, Jag and probably Tejas).

So, probably there was another person who hadn't listened to 'those lectures'.

And at the end, there is nothing wrong with those lectures.

No it is shameful to get your pairs back off.
And please do quietly increase your comprehension skills,youre taking those needles in the diff sense...fitting of an unknown radar is even more painful and still lags in performance...

No the rest is your lack of comprehension and sheer ignorance,you didnt even bother to look what i actually talked about and which i think is a time waste......I didnt said what you think i did(and if i did do tag again),uttam on Mig29 will lag in performance compared to the AESA radar designed for mig29/mig35by russians if equal contemporary Electronics are used....

Your understanding of matter is poor not mine. What AKM said is perfectly fine. Also LRDE and DRDO are doing what is asked of them. That doesn't take away from the fact that UTTAM with modification cannot go on other class of fighters.

I will leave at that. Good that you have interest in these matters, but don't put blinkers on.

That's why, I am saying, my comprehension is not at stake here, your's is. Where have I asked you to compare AESA radar developed for MiG 29/35 by Russians with UTTAM adapted for MiG 29? Have I?

You from the first post went on a tangent. And the reason for that was your lack of comprehension. Go and read the post from last page onward.

Neither you or the other poster Sharaswat are wrong, you are not.
But, that chip on your shoulders and your superiority complex hinders your response.

What you think is optimum, optimized while what 'others' (Elta/ IAI along with Romanians, Argentinian, Indian HAL) have demonstrated and accepted are 'jugaad'.

Now from technology, you are down to price. OK.

Try also find out how much the others took to fit the same radar on diff platforms

What it takes to clearly understand that performance wise,price,a radar which is not designed to fit on an aircraft compensates on above when it is tried to fit on another.....What ELTA radar on LCA had performance issue which has slightly improved,PAC report further says that 2032 was able to detect a su30 at 70kms with new radome(fighter size)(far less from the publish range but fitting the iaf requirement.....The last thing the scalability doesnt mean plug and play and it is limited to very small extent,and if hasnt been the case,US couldnt have developed so many x band aesa fcr of diff shape and size to fit on various airframes .....

see thats where the comprehension things comes up......Noone came with the fact that the radar cant be modified(in my term called the juggad,not the type of yours in which we are hell bent to make it possible). Cost of the modification and the performance are both compromised compared to the radar which is designed for the receipient one.....

You clearly dont willing to learn that basic im talking about.......Also mig29 quote was a mere example not a comparison similarly if you try to fit uttam on f16 and sabr on tejas,cost wise it will come out costlier and performance wise they both will lag than the benchmark set by the parent aircraft with the radar designed for them.....

Since we are buying 21 Mig29s, how about we retrofit UTTAM into Mig29s. We can retrofit UTTAM into LCA Tejas Mk-1 (IOC/?FOC) at an earlier date and for MK-1A during their MLU.

It's good that DRDO/ADA is confident that by the time MK-1A production begins, UTTAM AESA will be ready. What if it isn't?
My suggestion was in the event of UTTAM not getting ready in time for MK-1A.
Rather than just waiting for 4-5 years for fitting UTTAM into MK-2, why not 'negotiate' with Russia and fit UTTAM into Mig-29s in the mean time..

While retrofitting AESA radar into an old platform many things have to be considered including like the weight, the cooling required, the power requirement and other factors like wiring and cabling.
Aslo, the parameters you have mentioned are vital. But not surmountable?
Isn't the feature of UTTAM AESA being Scalable will come in handy here?

Isn't the very fact that some of the Mig29s will be retired in a decade a boon in itself? Retrofitting AESA in them will be a low risk affair. If successful very good, if not current PESA radar is good enough to see it fly into the sunset.
Also, newer Mig-29s (including the yet to be acquired ones) will serve for a lot longer time.

With this project the outcome of the possibility of retrofitting UTTAM AESA into Mig-29 K/KuB will be more or less clear. (Although they are made to different standard M/M2). Those Ks are going to serve for a lot longer.
.

I have never claimed that UTTAM will be drop fitted into Mig 29. Have I?

Here is a gist of my my query in this thread. The important points and last two quotes being the line of thought of DRDO. Readers of the thread are smart enough to deduce by themselves, what was the question and what solution was expected.

And what posters with a chip on their shoulders replied.

Nope you actually said that "scalability will come handy in use" sign of sheer ignornace about the very thing...

That's why I said, me and Sourav Jha both were bunking the Aero-India lectures.

 

[Chinmoy]

Is track range or max range more significant? Also is there a way to normalize the size of all the targets and then specify the track range for uniform comparison?

Both are significant.

One is important to detect target, other for tracking the target.

What exactly you mean by normalize the size of all targets?

I think canopy re-shaping will also happen. Along with other small changes. Also, any info regarding the re-design of the landing gear for weight reduction ?
