Correct.
And thats why IAF is so keen to get it right.

To gain knowledge and given our geography, land based fighters are very useful for fleet defense and knocking out of enemy surface targets. Right now the responsiblity of the IAF, these would allow IAF to use its assets for other priorities.

i can envisage air defense of andaman-nicobar chain given over to shore based naval aircraft, plus second layer of air defense around west coast, plus take over maritime strike from IAF, plus provide air cover for the fleet(s) from shore to extend the safe zone around our carriers

Plus Air defence in the Arabian sea from bases in Gujarat, Mumbai area and leave IAF assets to tackle the Paf.

I don't see any advantage in NLCA taking the role IM Jaguar.
Is there?
Is there any buddy refueling system in the pipe for LCA/nLCA?

Thanks for stating the obvious :roll:

If NLCA Mk 1 is not the future for IN, why just build 8 LSP? If Mk 2 has different aerodynamics then you need to test the complete envelope anyway, why do the complete envelope testing for just 8 Mk 1 LSP? Just abandon that and go the full Mk 2 route for NLCA and concentrate all testing resources on that.

Re: 8 LSPs of NLCA, the answers can perhaps be found in the last few comments in this thread.

Structural changes (LERX,etc ) will require non-trivial changes to FCS. This in-turn may require it to be requalified for weapons mix.

- If NLCA is going to take over Jaguar-IM role then it will need to be qualified with all those armaments. I don't IAF is going to qualify it's aircraft for marine role in a hurry.
- If they intend to add specific radar modes over sea, then that needs to be qualified as well.
- Datalinks to surface assets and other air assets with IN.
- Someone mentioned buddy refueling pods.

Still, it is likely that Naval LSPs will not progress as slowly as IAF ones and could be in the hands of naval aviators to achieve FOC sooner.

By sanctioning 8 LSPs, the message to ADA from the MOD/IN might be: "we want to see incremental but rapid iterations. So, dont worry about not having the budget for sufficient LSPs". I dont foresee maritime, land based operations for NLCA LSPs. If they wanted that, why not just order LCA Mk1?

India's first home-built carrier-borne combat jet may finally be powered by GE F414 engine that provides 90 kiloNewton thrust to meet the specifications for LCA-Navy
Thrust seems to be 90kn. wonder where they got that from ?

^^90KN for the F414 sounds about right. What is the problem?

F414 is 98kN engine.

http://en.wikipedia.org/wiki/GE_F414

Also interesting to note:
F414-EDE
The "Enhanced Durability Engine" or "EDE" variant, includes an improved high pressure turbine (HPT) and high pressure core (HPC). The HPT is redesigned to withstand slightly higher temperatures and includes aerodynamic changes. The HPC has been redesigned to 6 stages, down from 7. These changes were aimed at reducing SFC by 2% and three times greater component durability.
F414-GE-INS6
India’s Aeronautical Development Agency selected the F414-GE-INS6 engine to power the Mk II version of the HAL Tejas Light Combat Aircraft (LCA) for the Indian Air Force. The F414-GE-INS6 is the highest thrust F414 variant, and it includes a Full Authority Digital Electronic Control (FADEC) system. It will feature a six stage turbofan. The engine is to be delivered by 2013.
So INS6 could possibly be EDE if not EPE.

not a problem but there seems to be some contradiction on this. Rahul had mentioned 98KN in some thread, the same's on wiki aswell which rates INS6 to be the highest thrust version among 414 variant. somehow i remember reading a link which quotes a GE official claiming that INS6 would not be the highest thrust version of 98Kn

The basic F414-400 is 98kN. So, INS6 is at least 98kN. EDE has 15% improvement in thrust or increased lifespan at same thrust and reduced SFC (according to wiki), while EPE has 20 % improvement in thrust.

GE414-INS6 has 98kN thrust as per ADA.

Actually there is difference in the thrust of variants of same model also. For instance thrust of variuos versions of GE 404 may be 78 to 83kn while its wartime thrust my be say 83 to 88kn. Similary GE 414 may have max thrust of 94 to 98 kn with wartime thrust of say 98 to 104. So all the figures may be right :-)

Exactly. With money are material turning out to be are less of a problem, its only a question of human resources.

Engineers who build the LCA, test pilots who fly and provide crucial feeback, designers who incorporate iterative improvements etc. The next thing would be parallel testing by 3-4 aircrafts, qualifying different subsystems. People working in shifts could speed up things a bit.

If they have enough people (and more), a separate team could be put together for mating the K9 to an older Mk-1

Okie regular ritualistic whine, we reached the end of another month without the two birds flying. Anyways keep whining hoping for their flight

abhishekkaushal,
Nice artworks and its always good to have another 3D artist here. :)
However, if you would allow me to add a few points:
Your modelling is very good and rendering is adequate, but you need to do a lot more texture work before this looks photorealistic. At the bare minimum, you need to paint all the markings/graphics and then add a dirt layer. That will lead to a marked improvement in your artwork.
PS: Loved the mk2 model. :D

Hello Gaur. Thanks for the appreciation. I've seen your work and it looks great. As for the texture maps, I could've done if i had more time and patience. These renderings have been done with different software. Modeling has also been in separate package. Due to less compatibility of these, I've been having problem in export/import of geometry, which then comes out faceted in my renderer. So applying maps is not so easy for me.

Thanks for the thumbs up Abhishek. Also, considering the limitations you faced, you did a fine job indeed. Looking forward to more renderings from you.
Cheers.

^^ Lots of action in the skies yesterday...

Heard a roar and thought it was a Tejas and turned out to be a Su-30 doing some lazy loops before disappearing. Again, a roar in 5 minutes and turned up to see a Kiran doing some serious low flying and just when it went away, a metallic grey LCH with only tiger stripes and no colour on it (was it the TD-2??) buzzed past!!!
