So I don't understand what's the difference between this and ASPJ Pod? If we are fielding our own AESA Modules why do we need to import this again?

 

[E-195]

Back in 2012, when it really was...



No need for belly... It'll need to wait for CCM-dualrack pylon. May carry 4 BVRs in CAP setup, the Tejas counterpart of this:

A belly dual-rack BVR pylon is planned for Mark2. That'd be nice

looks cool

 

[rohitb3]

Endurance matters in CAP, a little less in interception mission. Instead of removing tanks , better choice would be fitting a 3rd BVR under the belly.

Fitting a 3rd BVR under belly may take time, and as far as we know in public domain, thats not an immediate plan.
Mig21s with a range of 660 kms(clean) has been doing a splendid job in India's past wars(without even having the ability to carry drop tanks on its wings), and Tejas mk1A with a range of around 900 kms(clean) suddenly needs 2 x drop tanks for everything?

 

[rohitb3]

In a2a combat you munuver alot reduce altitude drastically dragging aircraft into thinner air.
The use of afterburner is needed while cranking in order to evade missiles.

Yes, as I said for performing CAP we need extra tanks. On feb-2019 Su-30 and M2k were performing CAP operation with mig21. M2k has to be called despite base station being in Gwalior.

You're mig21s can't guide a bvr at 100km or even at 50km range still they play crucial role because we don't have enough replacements of them.
They're are not going to be used as Tejas.

2-3 things from my side ....

1 . Why tejas carries 2 drop tanks
Tejas is a multirole fighter , which will do a2a or a2s role if needed , in a2s role it has to fly longer ,so the drop tanks are there , where as mig21 bis was purely an interceptor , with 2 bvrs and 2ccms it can do it's task with limited range , so it has to deployed in the western most airforce bases .
2. Those drop tanks will be changed , in different scenarios , some times you will see 4 bvrs , 2 ccms and spj ...and 700 ltd dt at the central pylon

3. I too believe that central pylon can have bvr, but it must be a ejector lunched one , as Astra mk2 is , Astra cant be fired from central pylon.

4. I asked some one why tejas has that ldp pod , also with bvrs ...he said it does the role of irst in some extent ( Experts please comment on this )
5 . I have seen tejas with those two drop tanks , in western border iaf bases , may be iaf beleives that 2 bvrs and 2 ccms are good for tejas .
At last ......have you ever imagined tejas with 2 astras , spj pod , hammer , Jdam er

Many things will come ........bas dekhte jao

So no engines till April

 

[Spitfire IX]

Russia invaded Ukraine more than two and a half years ago, resulting in a shortage of titanium (and any other materials?) to western aerospace manufacturers. There may be more than that to the GE F404 delay but the root cause is Russia..

I think that India may have a legal claim for damages due to the delay in delivery but GE has the defence of 'frustration' - something beyond one's control that prevents one doing something. If GE stated in the contract that delivery dates were not firm, what remedy is available to India?

India's priority is to get fighters out of the door. The country needs GE engines to do that in the immediate future. The question is: what is the best course of action with GE to bring that about? Another matter to consider is the F414 contract. India does not want to delay that being signed by getting into a dispute with GE over F404.

Best thing, build K 10 with the help of others and if they can do it just to piss of Burger land, install and test AL-31 engine derivative in Tejas mk-2 prototype.

GE would definitely get Heart attack.

[Vishnugupt]

the root cause is Russia..

We should sanction Russia for GE engine delay

 

[SlayingHell]

In the midst of the GE engine drama and MRFA circus, one silver lining is that if the government finally wakes up and funds Kaveri or its derivatives, we could realistically achieve an engine by 2035.

The government needs to abandon the naive belief that the MRFA contract will lead GE or Snecma to hand over jet engine technologies. They simply won’t. They’ll find ways to fall short of full delivery on the contract, leaving the government to eat shit.

 

[Aaj Ka Hero]

We all have our dreams.

I think this is last resort, AL-31 is perfect candidate to replace any engine if designers of Tejas mk-2 design the engine bay in a way that fits it.
They are already designing it to fit different engines last time what I heard.
With this government finally running out of patience, certainly there might be talks going on right now to look at Indianised Al-31, we have already indianised it.
It's USA and it's allies who chose NIJJAR TERRORIST over India.
Not us.

 

[Aaj Ka Hero]

The Kaveri got rejected by the jarnails because these jarnails are thinking tactically, havent been taught to think strategically.
Ie, tactically, they want ze bestest product $$ can buy and that clearly is western engines.
But strategically, it makes us dependent on the west.

What China understood, that IAF jarnails did not, is that you cannot just rock up today, hire 1000 of the bestest and brightest in the world and crap out a top of the line ICE engine ( internal combustion car engine) , let alone a jet engine. If you could, China would've long since made its own ICE engine and had its own car brand.
Yet it does not. Why ?
Because ICE engines today are 4th/5th generation ICE engines and have been perfected so much, that a vendor with 0 years of engine development simply WILL NOT catch up for decades.
This is like asking Michaelangelo to make the statue of David when he was 15. Sorry, but cant do it, he needs a shit ton of experience and hard work first.

So if you cant do this with ICE engines, how can you do it with jet engines ? China for eg, accepted reality - that if they make their own engines, it will take 30-40 years for their engine to mature enough to be competitive with western/russian engines and they are fine- using their substandard WS engines over the much higher standard Lyulka engines.

I was told by an Israeli materials engineer friend of mine, who came to Canada for PhD over a decade ago and stayed only 4 months ( IDF flipped out when they found out they let this guy go, so they counter-offered his UBC PhD in materials science degree with a similar degree from U of Tel Aviv, with research position in a IDF lab itself and he went back home), that the Kaveri is a bloody excellent engine for a 1st gen engine: its only 5-10% more overweright and less Thrust-to-weight ratio than the 5th/6th gen engines.

But our jarnails basically want a desi to start a company today and in 20 years, be at the same level of development as its competitors who started 100 years ago. Thats just not gonna happen.

Best it's flat rated, so no matter where it's in it's designed altitude, it would still give desired similar thrust. No variation.

... Snecma to hand over jet engine technologies. They simply won’t. They’ll find ways to fall short of full delivery on the contract, leaving the government to eat shit.

Why tho? Safran seems to have delivered on the Shakti engine, well enough for us to go round 2 with Aravalli (for IMRH) and make HTSE on our own.

Arey baba- Shakti hotcore is from Safran from beginning and they held until recently closely and only parted with it as we developed our own HTSE, what is even the point?

Al31 is in totally different league compare to GE414 and EJ200. Also our Jurnails don't have much trust to go with single Russian engine. Porkies have somehow managed to not crash many jf17with rd93 , although availability rate and flying hours are surely affected.

But they did give, na? We had to do some jugaad to get final ToT but we are a respectable stage in turboshaft dev now because of a similar deal....

IDC if its shared IP, as long as type certification is with us its good enough ig, can slowly weed out the imported parts

the argument from GE would Force Majure.

Root cause is not just Russia but China too.
CHinks have gained monopoly on intl supply of Russian titanium
