the pics u posted r of a jaguar ..... r they planing similar modifications for lca ????

according to AJAY shukla ..they are planning to make intakes Auxilary similar to Jaguar..

Hi Jha,

the Air intake changes are already there in LSP 3 and LSP 4.

Thanks

Hi Dash,

As far as I understand the current EJ provides only 5-6 kn extra thrust [ge404 IN is 84 KN], I think what was on offer is upgraded EJ i.e. around 95-99 kn with TVC. Seniors please comment.

My guess is they will redesign the Air intakes as the Air force is not happy with the current air intakes.

Seniors please let me know if this is true.

Also according to ADA chief they have already formed 2 groups for both the engine changes to LCA. So Air intake changes may already be underway.

Thanks
Sri

yes..the engine on offer is upgraded EJ-2000 with 95-100KN thrust..
although currently it is having 60 KN dry thrust and 89 KN reheat thrust..

and yes as a lollipop they are offering single crystal tech...

Thanks..i just read the shukla's report..

One question for limited series aircraft-6 to be experimental, he says then how it inducted in first sq

LSP-6 will be used to further expand AOA and has per source will also be a test bed for AESA Radar

 

[Dash]

The only question here is current form has 90kN reheat, is it possible for them to get a 100kN engine so soon which can be inducted right away...???

Couldnt that cause delay in Tejas program?, need help in some link or any info anyone has on this.

which source ..... love to read it my self !!!!!!!! aesa radar ? which one ...India's own ???? u gotta be kiddin me !!!!

if its all true then i'wud be the happiest man on the planet !!!!!!!!!!!!!!!!!!!

plz reply ASAP

Both lca mk2 and mmrca not coming before 2013-14 or even longer ... so lots of time to upgrade and test !!!

but it all depends upon the mmrca decision (EFT)!!

EFT is no doubt the best fighter/choice as it will not be just buying/selling thing ...lots more will be coming with it !!!

Hi jha, I hope you realised that the shukla article is from 2008, so the changes he meant could already be done and maybe they are also a reason why the weight is down to 5.6t empty.

hey guys wats fe414 EPE(enhanced performance engine).... heard it is an upgrade to increase the thrust by 20%

if yes .......will it be used on tejas if fe414 wins ???

The EPE was offered to India, but it is not developed, so it will need time and fundings and that is something that MoD don't wanted. They rejected the Kaveri-Snecma co-development exactly for that reason, because they don't wanted further delays. The EJ 200 instead is offered with a slight thrust improvements (possibly 90-100kN) and so far Eurojet said they don't need any airframe changes, which should include air intake redesigns.
Imo, the engine that offers the least changes should be choses, to make the induction of LCA MK2 easier and faster!

India To Roll Out Tejas Naval Variant Soon​

Jun 22, 2010

The Tejas Light Combat Aircraft’s (LCA) naval prototype (NP-1) will be rolled out for the first time on July 6 here in Bengaluru, with Chief of Naval Staff Adm. Nirmal Verma on hand, sources tell AVIATION WEEK.

The Aeronautical Development Agency (ADA), which is in charge of the design and development of Tejas variants, and Hindustan Aeronautics Ltd. (HAL), ADA’s principal partner and main manufacturer, are currently giving the aircraft a final structural fine-tuning at HAL’s Aircraft Research and Development Center.

“The rollout of the aircraft signals that the platform is structurally complete, equipment installed, and plumbing and wiring completed,” a source says. “It will be on its wheels and can be moved by assisted power. A rollout is also a precursor to the next phase of ground-based system integration testing, engine ground run, taxi trials and the first flight.”

The NP-1 will have almost the same system architecture as the Tejas Indian air force trainer version.

The NP-1 trainer is scheduled to make its first flight by the end of this year and the NP-2 fighter one year after that. Both can operate from an aircraft carrier with the ski-jump takeoff and arrested recovery concept.

“The aircraft will get airborne in about 200 meters over the ski jump on the ship, [versus] a land-based takeoff run of about 800 meters,” a source says. “Landing on the ship is with an arrester hook on the aircraft engaging an arrester wire on the ship. The aircraft then stops in 90 meters, which is about 1/10th of land-based stopping distance. This makes the Tejas naval program extremely challenging, and we are happy with what the Naval Project Team based out of Bangalore has done so far.”

The 14-member NPT is headed by Cmd. C.D. Balaji (ret.), program director for LCA Navy, operating out of ADA.

The Cabinet Committee on Security (CCS) sanctioned development of LCA Navy in April 2003, and in December 2009 the CCS also approved a Mark-II version with a new engine. NP-1 will fly with a GE-404 power-plant, with 40% of the funding coming from the Indian navy and 60% from the Defense Research and Development Organization. The Tejas naval variant will replace the aging fleet of Sea Harriers, and the navy is said to have made an initial commitment to 50 Tejas after the platform proves its mettle.

A GE engine, means the plane is not all Indian. Hmm, interesting. What is the cost per aircraft?

Whats new in your post. This is well known to everybody and no one claims on the engines. Costing at this stage is difficult to put it from outside as there is no real per unit cost derived. There are lots of parallels between LCA-Tejas and N-LCA at this stage.

I bet 100 bucks that you dont know anything about fighter planes...

So, u plz tell us abt jet..........
Its radar is also not Indian
