ADA Tejas (LCA) News and Discussions

On the LCA project

The LCA is going well. We said the Initial Operational Clearance (IOC) 2 will be completed by this year end. IOC 2 is progressing very well and in spite of bad weather a number of sorties have taken place. HAL team is working well along with the Air Force and a very well integrated operation is going on. We are very confident that IOC 2 will be completed on time. The Final Operational Clearance is slated for 2014-end. Meanwhile, production will start from this year onwards and we expect that the first aircraft will roll out in 2014. Right now, we have orders from the Indian Air Force for 40, in 20-plus-20 option. The naval version of LCA is also going on well, Prototype Version (PV) 1 and PV2 are getting integrated, and PV1 should be completed by this year end.

It is 20 Mk1s + 20 options exercised in 2009 confirmed. Beyond that there won't be any more Mk1 orders. The next batch of orders will be for at least 83 Mk2s depending on how the Mk2 progresses.

No more Mk1s beyond 40 orders. That much is 100% confirmed.

The Navy has requirement for 45 LCAs out of which 8 will be Mk1s. The rest will be Mk2s. That's a total of 168 LCA Mk1s and Mk2s.

That's why a recent HAL paper mentioned the 178 aircraft potential orders including prototypes.

The 23 Coolest Military Birds In Flight Right Now - Business Insider

@ersakthivel

Isn't this a fanboy compilation (even though at Business Insider) ? I had seen it last week.

However, I concede that relaxed static stability is the latest buzzword aviators seem to be discussing (keypublishing & other forums).

But, there would never be any last word on fighter design.

The Navy has placed an order of 8 LSP aircraft (not mk 1).
http://ajaishukla.blogspot.in/2012/12/navy-eager-for-tejas-placing-orders-for.html

There would be five prototypes (NP +PV), with 3 based on GE-f404 (two double seater, one single seater), two based on GE-f414 (one double and one single seater), followed by 8 LSP aircraft based on GE-f414.

 

[p2prada]

Hmm, that's new. So 8 Mk2s instead, LSP or not.

I wud call it relaxed static shit. The pitch up rate is not the only parameter for ITR, roll rate is coupled with it. LCA has lower roll rate than even GNAT and Hunter. So if you combine the time taken to roll for a bank angle and pitch up rate, you will find that this relaxed static shit sold by Americans is of no use. Do you know that these so called RSS ac have pitch up rate sensors to limit the rate? RATE is what I stated. Hunter FYI had a roll rate of 720 degrees/sec.

Then Why all fighters like RAFALE, Gippen, TYPHOON and F-22, F-35 all are designed as RSS fighters?
If Americans sold it there is no reason Why the swedes, french, Europeans should all be buying it uselessly for no purpose at all?

It is not just pitching up fast that counts, It is how many Gs you pull in how many seconds that counts,

I think in next 2 days we will cross 3000 test flights.

will there be a ceremony ?

LCA Tejas requires a new radome | idrw.org

SOURCE :SP's Special Correspondent

As the Tejas speeds towards IOC-II, it appears that a crucial hurdle may slow it down, the platform needs a new radome. The Aeronautical Development Agency (ADA) has sent out an expression of interest to vendors to "design, develop and manufacture radome for LCA". The ADA's Directorate of Avionics & Weapon Systems in the EOI of September 2012 notes that it is "looking for alternative radome for LCA as part of their product improvement activity".

The EoI stipulates that the new radome is "to replace the existing radome with improved electromagnetic performance (EM) and with no change in existing geometry and pitot attachments." Also, the new radome needs to have identical geometry, though surface smoothness needs to be "equivalent or better". The document also suggests that the team testing the Tejas has issues with the lightning protection system of the existing radome and that there is rain water ingress at the radome-fuselage junction in the current structure.

3000 ????

it must be 2300

This is what slowing down ... adding improvements. all the way.. We cannot build the IDEAL AC. but we should move on...
Further delay is not so good on LCA project.

 

[brahmastra11]

sorry.. yes 2300

3000 ????

it must be 2300

LCA Navy Project Director, Shri C.D.Balaji interview to AeroMag Magzine.
Present status as of jan-2013?

Post successful launch of the first Naval prototype the NP1, Indian Navy has indicated interest in Limited Series Production (LSP) of 8 aircraft (4 trainers and 4 fighters) in the Mk1 configuration.

Broadsword: Navy, eager for Tejas, placing orders for 8 naval fighters

There would be five prototypes (NP +PV), with 3 based on GE-f404 (two double seater, one single seater), two based on GE-f414 (one double and one single seater), followed by 8 LSP aircraft based on GE-f414.

Highly unlikely except this sentence "to replace the existing radome with improved electromagnetic performance (EM) and with no change in existing geometry and pitot attachments." which is true ..

A few more squadrons of tejas will do a world of good for IAF,

product improvement is always an ongoing process. not a stumbling block in serial manufacture,

Ok, so the 8 LSP would be based on Mk1 platform not Mk 2. Thanks for correcting me.

But these changes can be added further..
I mean Delaying the IOC-2 at this stage is not good for IAF..
