ADA Tejas (LCA) News and Discussions

No it is baseline I-Derby...btw according to LCA-Tejas FB page Astra will be primary BVRAAM of Tejas

 

[Immanuel]

There is no baseline I-Derby, I Derby-ER is the one tested as I-Derby is the new variant. Older versions are just called Derby. This is a significant milestone. Astra will eventually be the main BVR missile for all IAF platforms by 2020

Saurav Jha tweets : Gun integration is not expected to be an issue for the Mk-1A certification program. ADA expects it to go pretty smoothly.

From one of post from BR..

So what's left for Tejas FOC?

1. Expand flight envelope to -3.5 to 8G (Currently -2 to 6G).
Done as per FB.
2. 24° angle of attack (Currently 22°).
Done as per FB.
3. In-flight refuelling capability (Integration of Cobham probe complete).
LSP-8 has been integrated with Cobham's IFR probe and is undergoing ground tests as per FB.
4. Demonstration of Rafael ADS Derby BVR air-to-air missile.
BVR missile firing to commence in Feb with LSP-7 as per FB.
5. Demonstration of Rafael ADS Python-5 IIR close combat missile (Related post here).
Probably same as above.
6. Completion of integration & demonstration of KBP Gryazev-Shipunov GSh-23 23mm cannon.
Removed from FOC and pushed back to Mk1A as per FB.
7. New design drop tanks for supersonic flight.
Is this done?
8. New radome to improve radar and electromagnetic performance.
Integration and ground tests with Cobham's Quartz radome have been completed as per FB. Flight tests to commence soon.
9. Validate more efficient cooling system for aircraft braking assembly.
Braking issues have been fixed as per FB.
10. Additional weapons testing, including PGMs.
1000 lbs mk11 unguided bombs, LGBs and PB500 successfully tested as per FB. CCM R-73 has been fired over a dozen times and has been guided by MMR/HMDS as per tarmak007.

Tejas Fires Derby Missile in Jamnagar
BANGALORE: Continuing with its successful stride of flight trails in 2016, India's Light Combat Aircraft (LCA) Tejas achieved a major milestone on Friday.


One of the limited series production (LSP) platforms fired a Beyond Visual Range Air-to-Air Missile (BVRAAM) missile Derby for the first time.

According to sources associated with the project, the LSP-7 from Tejas flightline fired the missile in Jamnagar as part of its scheduled weapon trials. These weapon trials are part of the Final Operational Clearance (FOC) mandate.

Sources confirmed to OneIndia that LSP-7 fired the BVRAAM Derby missile on a BNG (Ballistic Non Guided) mode. It was the 169th flight of LSP-7 and was piloted by Group Capt Rangachari of National Flight Test Centre.

Tejas is also scheduled to fire a Close Combat Missile (CCM) Python-5 missile as part of the FOC trails.

The LSP-7 along with LSP-4 were part of Indian flying assets at the just-concluded Bahrain International Air Show (BIAS-2016)

As reported earlier, the current trials are aimed at validating the accuracy of the missile.
Apart from Python and Derby, Tejas has in weapon menu Russian-made CCM R-73, laser-guided bombs (LGB) Griffin and Paveway and Russian-made gun Gsh-23

"It's a great achievement. We are awaiting the test results. The next schedule will be decided based on our analysis. We are awaiting the data," an official attached to the weapon trials programme said.

What are the main advantages of IRST as in Mig29 and Su30? Can Tejas be integrated with one in future?

 

[Pret]

They just provide passive search and track capability ...main advantage is that target receive no warning ( which is important for situational awareness and stealth* ) but Tejas-MK1A will have a AESA radar which itself have LPI so it doesn't need a IRST system but for ground target engagement LCA have litening pod

2. 24° angle of attack (Currently 22°).
Done as per FB.

AOA has reached 26*. This is an old news. So AOA might have reached well beyond 26* by now. Naval tejas in its first flight from Goa INS Hansa facility did more than 22*. So certifying it to 24* (i.e less than 2* of testing) should not be an issue at all. Plane has already done 8g in testing. It should still do higher g to be certified at 8g.

Indeed, it is only only with the indigenous Tejas that IAF has been so punctilious in demanding that the aircraft comply fully with every last ASR. Mirage 2000 was allowed to enter active IAF service without being armed with any A2G or A2A missiles, and for the first several years in 1 Squadron and 7 Squadron thereafter featured nothing by way of armament than its 30 mm cannon, which made this aircraft good for very little. But, hey, that’s a French plane! Now consider how sophisticated air forces handle new aircraft. The US fighter aircraft the F-35 Lightening-II has joined frontline squadrons without, however, being “battle ready”. Meaning that such faults as may be discovered in the underway “initial operational test and evaluation (IOT&E)” will be rectified subsequently in the aircraft already in service. This incidentally is the normal procedure followed by all major air forces. IAF is apparently not among them because left to itself it will be in no hurry to grant Tejas FOC.

Hence Defmin Manohar Parrikar has to step in. He can choose to be led by the nose by IAF, or use his common sense, see what’s being done by other air forces the world over, and order IAF immediately to give FOC to Tejas. And in parallel, he should instruct HAL to get into a ramped up production mode, with a whole string of MSMEs being transferred Indian origin technologies for them to produce and improve, and to procure TOT on imported components and assemblies in the Tejas, or hand them over for reverse engineering to a multitude of Indian enterprises. Normal ministerial prompting won’t do. Because IAF, seemingly insensitive to the indigenization imperative, has time and again shown by its actions that importing aircraft now constitutes its institutional DNA.

^They are ignoring Upgrades in MKIs ..obviously upgraded one would be more expensive

 

[Kunal Biswas]

Gud to see, Debry launched finally and Now its turn of Astra ..

 

[Pret]

'sar'..they haven't integrated Astra with LCA "yet"

I think the reporter has taken the broadest view possible of what constitutes as 'Make in India' and the article is more to do with joint ventures. It does not mention LCA, AMCA or the ASTRA and instead focuses on MKIs, Indo-Israeli SAMs (Barak I guess) etc, which is not truly what 'Make in India' is all about.

Also for the ALH project, the materials are imported which can't be helped if we do not have raw materials or more importantly, the processing plants to produced the desired alloys and metals. Also he is comparing with the cost estimate as submitted and not with other similar aircraft of the same role / class.

The media never appreciates anything related to defence. The silver lining, if you are looking for one, is that such constant criticism may well keep the defence sector pushing themselves to be better (just to prove the critics wrong).

 

[tejas warrior]

I believe this deal will go through.. not now but once MK1-A becomes ready.

All this joint development is just bullshit. Its just Russian and israeli shipped sub-assemblies and HAL just does the final assembly with a few parts sourced locally......there really is no TOT involved. Everybody knows this !!

Its just rebranding.....that all it is. And I am not the least surprised that it takes twice or 3 times the time it takes the Russians.

This reminds me of a former hardware company I worked for, that outsourced some software development work to India because it supposedly cheaper to hire software guys in India. Well to make a long story short......most of the code that was developed by the team in India had to be rewritten by our guys here in the San Jose, and it took twice as long, and all guys from India who came for 3 months training in the US ended up leaving the Indian contractor within barely less than a year after returning to India. So it was a revolving door, and the whole effort was an utter waste of time, money(millions) and project schedule. After about 18 months....they dumped the whole idea of outsourcing and moved the work back in-house.

There is no shortcut to aircraft or engine development. Manufacturing knowledge can be gained by in-house manufacturing but not design knowhow.

India has to go thru the painful LCA development process and take that forward to the next generation aircraft and involve the private sector if it wants a healthy defense sector.

I assume Navy's Tejas is going to take at-least 5 to 7 years or more to get into production, what's the point in integrating Derby to tejas when Astra will be available during that time?

It's better to salvage Derby that were order for Sea Harriers, because the shelf life of the missile might be 10 years I guess.
