@SavageKing456
So u mean to say that basically dry kaveri should have been tested by Feb (but might not be revealed in media)
So the next test will be for Kaveri in tejas (your speculation)
If you say yes then it's a great news

Russia ukraine war delayed the flight of dry kaveri engine
It was said by SJ that kaveri(not dry version) will be tested
But still don't hope much

But tested on what ... imo .. having a drone test bed is smart... that way you don't risk a pilot.

I Don't think this is correct news. So where would you employ this?? On ships, No, it's too big. On land, wouldn't a guided ASROC with LWT be better. How do you achieve kill chain with above pinaka based system????
Dia of LWT- 334mm, Dia of pinaka -224mm, so forget about guided torpedo solution.
Either we need a definitive proof of such system, otherwise looks total logical bullshit to me. If a mini SMART would have been pitched, then atleast that was believable.

RBU-6000 is itself based on SMERCH. So its not illogical to develop a Anti sub rocket based on Pinaka.

The news is DRDO and L&T is developing a completely new Anti sub/torpedo rocket based on Pinaka system witha complete new launcher system. The extended range anti sub rocket has already been developed. Now they are working on a much compact Pinaka based launcher.

This is complete RBU-6000setup. No where it is a small compact system.

Kaveri will not go into Tejas anytime soon, which is a single engine fighter. Not until it successfuly demonstrates few 1000 hours in a flying testbed with another backup engine over the course of next 5-6 years. If it cannot match the thrust to weight ratio of Tejas, IAF will not accept it over f404 that has very high uptimes with very minimal maintenance

It can go as a TD, and will be a huge relief to all those worried about american sanctions.

any Indian startup doing research on it ??

IIT Guwahati has developed such technology

IIT Guwahati team develops efficient perovskite solar cells to produce electricity from sunlight

These devices were developed achieving power conversion efficiencies beyond 21 per cent by utilising economical solution-based photovoltaic device processing techniques at mild room temperature and realising high ambient, thermal and optical stability, the researchers said.

Also there is a company named P3C

Perovskite is not ready for large scale commercial use yet. It is much cheaper than normal solar (1/10th or something like that), but the problem is its not very stable. So, its life is few months instead of 20 years of normal solar panels. Although, that was when I last read about it, lots of research has been happening and its life is increasing pretty rapidly with new research .

wait why are they testing the lca mark 1 now?

 

[ym888]

There's a religious service here?

 

[ezsasa]

wait why are they testing the lca mark 1 now?

To calibrate/compare the results on the new test rig with fatigue tests already performed else where.

 

[India Super Power]

There's a religious service here?

We generally do puja before the project and even in end of it
For good luck and hope of being successful
India is land of Hindus
So others may celebrate but we pray to our Supreme power

To not worry about us sanctions, it must mature and reach a stage where it can be integrated to entire Tejas mk1 fleet and they can sustain high sortie rates thats needed for wartime.

And PLA airforce university latest research on Transperent (infrared emission less) microwave radar absorber, published in latest issue of infrared physics journal, application in frequency selective surface in 5G platforms

The compatible method of designing the transparent ultra-broadband radar absorber with low infrared emissivity

The multi-spectrum compatible design of electromagnetic (EM) waves has captivated great interest since metasurfaces emerge as a novel structure design…

I would argue the utility of a 9km max anti torpedo system over a nearly 30-40km ASROC like system. Anyway a submarine can easily outrange any kind of rbu system and the utility of rbu as torpedo self defense is vastly exaggerated as it can atmost be used to disrupt wire guidance of torpedos, not stating the fact that tracking the path of torpedo in itself would be highly difficult. The space used by 2 rbu systems can easily be replaced by 12-16 ASROC type system. There's a huge reason other navies have moved away from such system and inducted ASROC type systems, even Russia and China. Pakistan already have DM2A4 seahake torps, I don't really think we should waste our time on rbu systems anymore.
Anyway where would you install this new launcher??? At best these can go on 16 ASW-SWC, others have already been fitted with Russian one.
And the most important part is that we don't use 90R guided rocket and the new drdo ER-ASR is also unguided. Wastage of resources in my view.

This study is being carried out to replace RBU. You are just saying the same thing on loop.

ASROC is a good anti sub weapon, but RBU is just like a sidearm an infantry man carries along with his main arm. RBU has seen its prime and is getting obsolete now. So we need something to replace it. A anti sub/torpedo rocket is much more cheaper then a onboard torpedo which again is much cheaper then a anti sub missile.
