Sukhoi Su-30MKI

To add to this, let me say something which I admittedly don't know for a fact with regard to TRMs but from general knowledge regarding such parts as computer PSUs. Usage of GaN would have an effect on this, though I cannot be sure as to the extent & the specifics.

Besides what I've already stated in post #3257, there may be several reasons why you'd want to put TRMs rated for higher wattage on your radar, even if your cooling system is obviously not capable of dealing with a full array operating at peak transmitting power.

Take the example of a 20W-rated TRM. While 20W may be the peak transmitted power, the peak efficiency is likely to be achieved at somewhere between 50-80% of the rated power depending on component design. Efficiency meaning how much power you have to input in order to get a set output. Closer to the peak rating, the efficiency drops off drastically.

So getting a 20W TRM would be a good way to ensure that operation at somewhere around 10-15W is performed with superb efficienc
if we put full number of 3,665 T/R modules as @South block said, can these modules be wired to receive other modules signal like we use only 500 modules at a time to transmit and use full 3665 to receive?
for the next pulse use other set of 500 modules to transmit
like a time separation to limit power and heat.
also in emergency case we should be able to use all 3665 to transmit in a burst mode for few pulses to get max power.
how about using a RAT or pod to get more power

Forget the 3665 number...it's not practically feasible. There's a reason why we limited the number at ~2500.

Yes, all AESAs are capable of functioning like this.

also in emergency case we should be able to use all 3665 to transmit in a burst mode for few pulses to get max power.

I'm sure there is a set limit for how long the TRMs can function at peak output without damaging the cooling system. How many TRMs can be operated at peak power at the same time is not public knowledge.

There are multiple ways of increasing input power, as long as your cooling system is capable of handling the increase in heat. If it's not, then there's no point in increasing input power.
 
If there is any AL-41 components related upgrade, we would have known. AL-31 TBO of 1000hr was minimum requirement under the original contract of MKI. It was done iteratively in early 2000's by Russians. HAL must have participated in limited way.
AFAIK, the newer batches of AL-31FP will have FADEC just like 117S!!
Good but still need to cover the upper aspect which will require drilling of frame @randomradio

FADEC already exists. Newer batches will have incremental improvements. HAL could have done so many smaller improvements like these if they have planned better.

Never heard anyone from Airforce talking about the need to upgrade the engine. They are happy with whatever they have, weirdly.

Yeah but an indigenously improved and uprated AL-31FP, that has better TBO, SFC and SEP won't hurt me thinks. So 'why not' and not 'why' should be the question!

Did a bit of data mining & this is what Google AI Search threw up .

India, Russia Explore Joint Production of Sukhoi Turbofan Engine

In Depth: HAL-Russia Licensing Deal for AL-31FP Jet Engines » DefenceXP - Indian Defence Network

While there's no mention of any AL-41 components being used it does talk of extensive collaboration between HAL & Russian agencies to mfg the AL-31 FP TF in India.

We can extrapolate that precise information towards this could've been suppressed given the sanctions in place against Russia .

At the same time India'd be seeking to emerge as the go to country to overhaul all those Su-30 Russia's exported across the world & this visit apart from seeking tech transfer among other items on the agenda was also about working out the modalities towards such an eventuality without attracting much attention.

Since there's nothing in the public domain to either confirm or deny such a move all we can do is indulge in informed speculation.

The good part from your PoV is at least your favourite I D R W isn't indulging in such speculation for once.

Why should be is common sense. Why didn't HAL do anything in this direction for last 20 years is the question.

They did more with Adour engine than this.
 
DR 118 is now passe since MKI UPG. would very soon get DR 140 or RWR-NG with full intercept window from 1GHz to 40GHz.
Newer Russian RWRs are very feature rich. It shows the direction, the signal strength of the incoming missile. It can also determine the type of threat. These are very useful information to have when defending:

We know the DR-118's monitor displays signal strength & direction. But we don't know if the RWR can do threat discrimination.

That along with new HBJ pods shall reform MKI's EW substantially.
Yeah, on the jammer side we are pretty sorted. What worries me if the IR side. Are we going to get the fuselage mounted DC-MAWS?


Why are we going for podded DC-MAWS? This just takes up hardpoint. Instead of a podded MAWS we should try to get podded DIRCMs. A podded DIRCM will have limited coverage, but something is better than nothing.
 
I think it might be prudent to increase the order that IAF had placed earlier for the MKI. Considering the environment, threat level, operability, and availability the MKI can be procured in greater nos. and will be available in a couple of years. The upgrade for it has already been approved. DA will not deliver Rafales before the end of the decade. I am unsure of the Mk2 timelines and remain skeptical about the statements coming out of MoD or HAL. Indian weapon integration and network operations should not face any challenges as well.

If you'll be opening the production line, might as well give this thought. I had written about this earlier as well and inspite of this being an older airframe the pros in the near future seem to outweigh the cons.

On 14 Oct 25, IAF Sukhoi-30 MKIs, Jaguars, AWACS & AEW&C aircraft joined Royal Navy F-35Bs from HMS Prince of Wales for a joint exercise over the Indian Ocean Region. The training strengthened interoperability, mutual trust, and collective commitment to regional stability.

I guess sukhoi's and jags were simulating anti ship attack and f35B's doing CAP for fleet defence.
