Now Tejas future looks more bright with SEF out of competition, and double engine birds also getting in, this will lead nowhere.

Maybe MiG 27

AFIK, Jaguars have bullet-proof glass. MiG-27s have some armor plates that can be attached to the sides of the cockpit on the outside.

A modern fighter plane being shot down by a 7.62 round is quite laughable :D

Looks like few 414s are already here waiting for Mk2.

As per news that came out of AeroIndia 2017, 2 engines were already delivered by then and six more were scheduled for delivery by the dnd of the year. So ADA should have 8 engines by now.

Aren’t canopies of supersonic aircraft bullet proof already?

https://twitter.com/SJha1618/status/967018626875363328 ---> Indigenization is the only way in which India can prevent itself from being caught on the wrong foot due to geopolitical shifts. Which is why the Tejas program must assume top priority.

https://twitter.com/SJha1618/status/967065652166053888 ---> There is no point in talking about being a capability oriented military , if that capability is acquired via imports. Then you remain a threat based military without independent capability.

It was/is 2+6 engines for Mk2

GE supplies two test engines for Tejas Mk-2, eyes collaboration for AMCA
http://wap.business-standard.com/articl ... 120_1.html

Followed by 120.

So, V&V : 120 + 6 .. we are talking trashing the SEF no matter #of injuns for MMRCA.

Breap request: pl keep that thread locked till Mk2 shows up safely.

The way I hear things are moving, MK2 will be a DRDO affair ;) Anything ADA wants to do is being pointed to a DRDO lab.

In other news, my KB have practically moved on. 'Bloodsucking Private Enterprise' can't wait forever for anything you see? We have other exciting things to do anyway.

DRDO affair meaning led by the ADA? Wasn't that how it was always meant to be? Or are you saying that other labs are also going to be engaged more widely?

HAL proposed the Mk1A primarily because it changed some of the avionics systems and LRUs and their placement to better meet IAF needs, but didn't modify the OML of aircraft, which would've entailed an all new set of design, CFD and wind tunnel tests.

^^Yes, it always was 'supposed to be'. ADA was 'supposed to be' a co-ordination agency between all the govt and private entities. But what actually happened was, they ended up doing a lot of work on their own. They got a world class successful product to show for that.

That is being de-constructed now.

We work with a number of DRDO labs. I am concerned.

I couldn't care less about what ADA was meant to be. Fact is they have always been dependent on DRDO for most of the heavy lifting and if finally, some common sense has come in to the powers that be, to move non core activities out of ADA into DRDO labs, then that is a good thing.

DARE does mission computers and EW.

ADA went and started its own MC team. HAL did the same. This sort of duplication is hardly helpful.

ADE did flight control but it was then split between NAL and HAL as well along with ADE. Almost all the subcomponents in the LCA are either from DRDO or HAL and it is to ADA's (dis) credit that they didnt work with private industry and DRDO enough to indigenize LRUs for which competence already existed within India.

ADA was meant to be a world class project management organization.

Instead they are a jack of all trades and have their fingers in all sorts of pies where they should have walked away from, while keeping their focus on important things. AVM Rajkumar mentions till he joined ADA didn't even have a plan in place to test the MMR, and he initiated the Hack with CABS.

For all the good ADA has done, it must also be understood they have not exactly really managed project handling that well.

I'd rather they focused on that, and high-level design plus production engineering and moved sub-system designs to DRDO labs.

Being concerned about the DRDO labs is all very well, but somehow they keep churning out products which are getting accepted by the services while ADA has to focus on delivering the definitive LCA and meet user requirements.

Just look at the RCI-DRDL cluster and their speed of development versus the two steps forward one step backward dance ADA-HAL combine have managed so far. The lack of synergy is evident.

^^^

Given that DRDO restructured itself into seven technology clusters around 4-years ago (http://www.drdo.gov.in/drdo/English/ind ... chclus.jsp) to streamline efforts, ADA (as well as HAL and other private firms) would need to work with various clusters as needed. That change seems to be taking place.

Primarily, they would work with DRDO Aerospace cluster, which comprises of the following labs:
  • Aeronautical Development Establishment (ADE), Bangalore
  • Aerial Delivery Research & Development Establishment (ADRDE), Agra
  • Centre for Air Borne Systems (CABS), Bangalore
  • Defence Avionics Research Establishment (DARE), Bangalore
  • Gas Turbine Research Establishment (GTRE), Bangalore
  • Center for Military Airworthiness & Certification (CEMILAC), Bangalore

A different thread for Mk II is warranted now. Let’s build the body of knowledge and some spill over positive vibes for Mk II.

Will Srai ji take the mantle of starting and manicuring the new Mk II thread?

MK II will practically be a new plane with same wings as MK I. But are we there that it warrants a new thread? A place like India, where secrets are kept in sieves, I would be astound if MK II has made any progress than chai biscuit discussion (or else we would have heard). If they indeed kept it under wraps and MK II is ready for HSTT, desh badal raha hai!!

It's nowhere near being ready for HSTT. Neither is the Mk1A. Please keep realistic expectations.

Just a data point to be added to the existing list being maintained for Tejas LSP and SP first flights, source is Tejas.gov.in

SP-5- Tejas SP-5 completed its maiden flight from HAL Airport in Bengaluru on 9th Feb 2018 piloted by Gp. Capt. KK Venugopal (Retd).

"Great Expectations".The title of Dickens' classic novel could very well be the title of the history of Tejas.Notwithstanding the effort put in thus far by those concerned, we havd yet to master MK-1 production, test the 1A and haven't even seen a mock-up of the MK-2.Thus as a member has well put it, let's be realistic.But what the decision to scrap the SEF has achieved is to leave the field wife open for Tejas to storm through provided HAL/ADA get their act together.

Actually - "Great expectations" should be the label of the trillions in man and machine invested by successive GOIs in purchase of maintenance intensive and low up time Russian systems purchased to date - be it ships, submarines, aircraft or tanks. The modus operandi of the armed forces to combat the poor up-times has been to buy in larger numbers so that a minimum is available when needed.

You cannot master production of anything by producing 20-100 units. HAL, DRDO have delivered a platform that can form the backbone of IAF for years to come. Compared to the Mig-21, this is a far more capable aircraft and deserving to be bought in numbers.

[Edited]

Tsarkar Sir IMHO, the radome blame has to be shared by IAF and ADA equally. As a customer if you are buying(and going to maintain eventually) a product that is in making do you not ask for the specs/KPIs of all the subsystems ? I ahve done this with my subsystem suppliers and keep track of the requirements and commitments. The fact is IAF was never invested in the program until 2008/9 and then started looking at this with one eye with the hope that they will get shiny Rafales. OTOH, ADA should have presented the numbers/KPIs and asked for customer feedback, may be they got feedback pointing towards improving the range or may be they didnt, we dont know, but both of them are to be blamed for the radome stuff. Similar things happened with flight envelope(ITR/STR) etc. You can possibly say that they were in the GSQR but the GSQR was written in 1983/4 and any sane engineering manager on the customer side/development side would want these to be revised to get a product out.

Nose cone problems were identified and solutions found. The delivery of the nose cone was delayed well beyond normal delays. Did the nose cone have to hold anything up? It was understood what improvements would result.

How may refuellers does the IAF have? How many are serviceable at a given time. Would such an extremely limited resource be reserved for strikers or point defence aircraft? So why does FOC have to wait for IFR?

Hot refueling on Tejas successful

(Unedited release)

Inching close to Final Operational Clearance (FOC), Hindustan Aeronautics Limited carried out a hot refueling on indigenous Light Combat Aircraft-Tejas followed by a sortie at HAL airport, Bengaluru yesterday. The system performance during the refueling session was in-line with design requirements and was satisfactory.
In the history of IAF aircraft, LCA will be the first aircraft to fly with this unique capability of hot refueling and HAL has successfully demonstrated this on LCA Tejas LSP8 aircraft.
Hot Refueling is a single point pressure refueling of the aircraft with the engine in operation. It is a process by which a fighter aircraft is refueled (in between sorties) while its engine is in operation, thereby cutting down the refueling time by half and turn-around time significantly. This capability is highly desired in combat situation which basically puts aside the need for the pilot to park the aircraft, power down and exit the cockpit for refueling to begin.
Further, with this, a major requirement of LCA Air Force Mk.1A has been achieved.

Yeah, it does not add up. Maybe that intake cover is a mesh for safety. But then the obvious question is how did they put the mesh on with engine lit and hight intake suction?

I am not sure that pic with the mesh on is the Hot refueling, it probably is a dated pic of LSP 8 with the Fuel probe.
