Hmmm, LSP-7 has just 1 initial flight. Wish LSP-8 takes off and both these birds start getting tested by the AF.

My guess:
LSP 7 is getting a coat of Tipnis grey before heading to Sulur.
LSP 8 will have its first flight "soon" (by 2013/2014), and it will be "very close to the actual production version". :evil:

During 12th Plan period? So the delivery of LCA can be as late as 2017? I really doubt a plane with a design of 1990 can do anything significant to improve the capability of IAF by then.

Compared to MiG-21s, it can be equally significant or insignificant even in 2017.

If you don't think about twin engined modified medium to Light LCA-3 - subsequently leading to AMCA. BTW, how do you compare Mig21s with LCA as the former is an outright purchase vs. self development.. so you are saying all those efforts are trashed [unless you consider the option of continuous development]

LCA NP1 problems :((

Govt appoints committee to probe LCA-Navy landing gear problems


committee has been set up to fix the problem delaying the debut flight of the home-made Light Combat Aircraft-Navy (LCA-Navy). The committee has been set up by the Aeronautical Development Agency (ADA) and the Centre for Military Airworthiness and Certification (CEMILAC) to fix the aircraft's heavy landing gear which is causing problems to the aircraft.

Usually, the world over, naval planes carry an extra weight of about 600 kg, because of their landing gear, also called the under-carriage. But the Indian LCA's (Navy) weight is about a 1,000 kg extra, the reason for which has been given as extra safety. The US Navy, which is being consulted by the ADA, has said that the safety margin taken by India is five times than what is required and needs to be decreased to the level the world over. The aircraft is being to land because of its heavy under-carriage and has not done even one test-flight.

The aircraft, which lands on runways, follows a speed of three metres per second while descending. The ones landing on ship decks (aircraft carriers) have a speed of seven metres per second during descent. It is for this reason that a heavy under-carriage is required — to absorb shock. For runways, a flared landing is done, which is when a fighter aircraft lifts up its nose a little before the final touchdown, unlike a deck landing which is "unflared". A deck landing is precise because of the scarcity of space. An unflared landing also gives the aircraft the momentum to take off again in case of an emergency. The naval aircraft are supposed to land with a "thud", thereby stopping there and then, because of the shortage of space. This is achieved by the arresting wires hooking the tail of the aircraft. There are three hooks for safety purposes, and usually Indian aircraft aim for the middle one.

One of the possible changes that the committee might make is changing the composite material of the aircraft, which has made it heavier than required. A source told this newspaper, "Since it's an indigenous effort, even if the material is changed, it will be Indian."

Meanwhile, Defence Minister A.K. Antony informed Parliament this week that the probable date of the completion of the aircraft is now December 2014, four years after the original date of March 2010. The original cost of the programme has also gone up from Rs 948.90 cr to Rs 1,714.98 cr.

Antony said that the probable date of completion has been extended within the sanctioned cost and scope. He attributed the delay to technical complexities, non-availability of infrastructure and critical components and technology denial regimes. Other reasons cited were the increase in the scope of work, the extended user trials and the failure of some of the components during testing.

The minister assured Parliament that the project would be completed without any further delay, for which a consortium approach has been used for the design, development and fabrication of critical components. A three-tier project monitoring approach is also being followed.

By 2014 the aircraft would attain compatibility with the aircraft carrier after its mandatory trials. It would be a part of the fleet onboard India's first indigenous aircraft carrier.

Hello,

I would like to know the opinion on something. Our Tejas is not supposed to be a frontline aircraft in the IAF, more like the defensive bird on CAP, etc. Also, it seems it will be cheaper to operate [single engine, light weight] Also, our immediate neighbours have nothing that completely outguns the LCA [J-10's, Bandar, and assorted obsolete models]

So when the media crows on the failures of the LCA, it is with respect to bigger and more advanced planes like the EF and Rafale. Not in terms of aircraft the Tejas will most likely face.

Hence ......... we can order more planes for now right? 100-150 of them? We can safely wait for the AMCA and PAKFA that way.

Its high time we had some guidelines/ minimum qualifications for journalists to write articles/ report news on defence. Its a no brainer to compare LCA with F22. Yet to see a single article in the national newspapers that compares LCA with J-10 or the FC-10.

for all we know, they (journos) may be just reporting as they hear it. We have no idea who they contact and what has been said. given that their knowledge of advanced technology, what else one would expect.

now, there is another way to get this straightened up. have drdo/mod/orgs its reuter/pti interface kind of service.. and all journos need not leave their office to get news! anything outside such an interface, is bogus! and people trash it.

In my view you have combined history, technology and geopolitics in one question.

The MiG 21 was a point defence interceptor and about two decades ago the Tejas was aimed as a MiG 21 replacement. Even back then the Tejas was never viewed as being an exact replacement but, as the Air Chief put it, a MiG 21 plus which could do more than the MiG 21. That is greater attack capability and range (over and above the planned tech advances) But over the decades of development views on Air Warfare and aircraft changed. Some concepts went out the door and others came in making the LCA program relatively aimless as a fighter, but well intentioned as a tech development platform.

The biggest changes since the LCA was conceived was the development of avionics leading to the concept of swing role aircraft that could perform both attack and defence roles, smart munitions making 1 smart bomb=10 unsmart ones, and advances in engines that made them more powerful and efficient. Because of this the requirements from a Tejas type aircraft began to creep up.

The Tejas has turned out to be what seems to be a decent aircraft which will not be limited to a defensive CAP role. Since one PGM is all that is needed for many targets, the attack role, even with a relatively light load is not ruled out and the Tejas is small and stealthy. So the idea that it cannot serve as a "front line aircraft" is wrong. It will be front line all right, but for a specific range of roles that match its capability.

Ordering 150 planes right now assumes three things. One is that the development is complete enough to "freeze" the design and fix a price for the order, second, that the assembly line and the manufacturing chain is ready to absorb that order and third, that the IAF can quickly figure out the roles that the Tejas would excel in and gradually remove other aircraft from those roles. I think that sort of situation is some years away yet.

^^^ one way to look at the history of Tejas is that DRDO/HAL set out to build a 'Mig21+ clone' but ended up building a 'Mirage 2000+ clone'. the benefit of the programme is more about the mil-eng-complex development rather than the aircraft itself.

(I am using the term clone in a very loose sense, before jingos get their dhotis in a twist)

Thank you for the post, very insightful.

Indeed, my question was very broadly put. As an arm chair general, I just find that the Tejas not being supported as well as it should have been. My weak heart cannot but feel fearful of the PAKFA/Su 30/Rafale dominating the airforce for the foreseeable future [Not a bad thing .. just .... a nitpick in my mind, fearful of Indian tech getting sidelined] Without the Tejas having sufficient bulk, how can we expect the AMCA to fight its way in numbers into the air force?

Again sorry for the rant/OT post ..... Fingers crossed for everything to work out fine :-?

Per discussion, AOA which I think right now is restricted 24 degrees, to increase it by a few degrees.

My secret wish, Kaveri and LRDE AESA is being fitted on it. :D

LSP 6 will be/ is being (?) fitted with a spin recovery parachute which will then enable it to perform High alpha and high G testing to expand the flight envelope.

IMHO these are very critical tests, the likes of which have not been performed in India before. So, they will try to keep as much of the plane standard as possible to concentrate on tasks at hand.

Having said that IIRC i read somewhere that once LSP6 finishes high alpha/high G testing, it will be fitted with Kaveri (if Kaveri is ready by then).

This a 95% fear or insecurity feeling that is common when products are not in use. The reason for staging success is make the user, use the product and feedback into development process. As of now, from test pilots report, it is A+. That should give you some factors to reduce that fear factor to 75%.

Usability is very important.. and once that is experienced, then make the development cycle close loop from user feedbacks. It is important to not ignore the user at all [especially, when the user has options].

It is very important for ADA and DRDO to stage plan their growth to AMCA. This has been said 1008 times. Staging LCA into multiple blocks to AMCA is the only way to make user realize AMCA.

LCA-mk-2 must be in the services before AMCA project charter makes sense.

LCA-mk-3 a twin engined mock of crude AMCA [if we follow the french, then just like M4K they did], is the best option.

To best put, just blindly follow France in the process of engineering and setup. /minimum requirement

Prasobh,

You probably know all this, but anways, the air campaign won't be fought like in 65/71. We are adding force multipliers for a reason.

The initial wave will clean out the front line radars/missiles as much as possible giving clean ranges/locations for other CAS planes to do their work. So once the area is clear from heavy duty ground to air stuff, cas will start and so will ground forces. Awacs will provide top cover for all CAS crafts doing their work. Not every plane needs to be gold plated or have gizmos coming out of its cute butt. LCA/Jaguar/Mig-27 will have to deal with hand held G2A missilies like cortale or stingers for sure, but they don't need to carry every eletronic wizardy carried by MKI/Rafale.

Even a updated Canberra which can drop Glonass based jdam type munitions will fit the profile just fine. LCA is miles ahead of that game. So I don't think there is much to worry about. We are now working to get a system in place . We are moving away from Mano-a-Mano kind of game. That game of chess is over. No longer are we just going to field the same number of pieces that our enemy will. Wars are won by having effective logistics, support and transport arms.We are doing well on all those. So every single day we continue on the path we are on, we are unlikely to lose.

@ Saik : Did not know about the Mirage 4000, thank you for the gyan. Definitely see the resemblance to the Rafale!

@ Cybaru : True, I have considered that actual numbers of aircrafts/tanks/ships cannot vary during wartime from peacetime because of the great amount of time it takes a modern weapon system to built. Months for planes, years for ships, etc. Indeed, modern war will be about utilizing and protecting your assets during war than attrition based wars like WWII.

^^^

My guess would be FOC at 2,500 flights with full IOC happening at around 2,000 flights.

"Marriages are made in heaven".Kaveri and Tejas were never meant to be mated and they never will! Most of the time that Kaveri wass tested in the air she blew up,according to reports.She was never fated to fly but must look for another more suitable environment to find a mate.Kaveri's best chance of finding a mate will be one of the IN's corvettes or missile boats of the future,after all the Tarantula class PGG engines are derived from aero GTs.The matchmakers spoke of this option some years ago,but unless they too get off their backsides and start looking at horror-scopes fast,Kaveri will be left on the shelf!

PS:Forget about inviting French beauticians to doll up Kaveri.They will steal Kaveris fiancee from under the noses of her parents,with or without their permission.

PPS:The most difficult thing to do in almost any discipline is to make something smaller,perform better and more tasks.This was predicted by a famous French philosopher about 100 years ago ,who said that concerted and continuing "miniaturisation" of material manufactured objects would prevail and that the globe would be surrounded with a kind of "...sphere",I think he called it the "oosphere", linking minds across continents.Today we call it the Internet!

This has characterised scientific development particularly during the 20th century.Therefore,the concept of Tejas,should be a serious philosophic and scientific study for the simple reason that globally,while many other similar projects have arrived (like the Gripen),Tejas has yet to evolve into as perfect as possible a functioning product as envisaged.Surely the march of human progress and miniaturisation of material components would've helped Tejas to achieve its goal of being the "smallest,lightest,multi-role fighter",.But the very opposite is seeming to appear,a new heavier engine needed to power a larger more powerful bird,Why?
The foll. paper is worth reading to understand the philosophy of change in human civilisation,before we set ourselves the task of rescuing Tejas or morphing it into something else! I'm being serious.
