^^ yes, in 1st video it does slow pass. In second video right at the start its triple roll which is quite quick as well (no less than 300 deg per second, I would say). Whats the specified roll rate for LCA anyway?? (EDIT: I miscalculated, its actually only about 1.75 rolls in about 3.5 sec giving approximate roll rate of 180-200 deg/sec)

Looks like President will be there and there are some serious driving and parking restrictions in the whole area. Just warning would be photographers to account for that


Yeah..For 2 days its gonna be hell lot of traffic near HAL.
But since my office is near HAL, I can see the airshow from office terrace also. In fact today I saw Tejas display from office. Wish I had 400mm telephoto lens.

The airshow is for HAL staff/families only it seems. Not even media got invitations so far, per AKN's (tarmak007) tweet. :x

One of my colleagues who was ex-HAL herself and her husband is presently working in HAL did not even know there is any such function.. :(( :(( I asked her to give me her pass if she gets one, since she is not interested.. :roll: :roll:

Even in the second video, the roll and turns are sharp, nice and smoother than what we have seen before

In the frames after the rolls, it drops flares and does an "S" manoeuvre in the horizontal plane. Now to do that kind of S, it needs to pull quite a bit of Gs and that kind of manoeuvre sucks up massive amount of energy.

For eg, for the space shuttle to decelerate after entry (at around mach 22 or so) , they go doing a series of very large "S" loops to bleed off energy and get to landing speed.

Another view on LCA in IAF:

Need to Fast Track the Induction of Tejas
#1484 461 December 11, 2015 By Radhakrishna Rao
Abstract: The Indian Air Force(IAF) is exploring all the options to boost its depleting squadron strength and meet its operational requirements in a time bound and cost effective manner. With the much debated Medium Multirole Combat Aircraft (MMRCA)tender being diluted to the outright, off the shelf purchase of 36 Rafale aircraft , the only feasible option open to IAF seems to be the induction of the home grown Tejas Light Combat Aircraft (LCA) in sufficiently large numbers.

___________________________________________________________________________

With the ruling dispensation in New Delhi clearly set against the import of fighter aircraft on a scale that would immediately mitigate the serious problem of squadron depletion haunting the eight decades plus old Indian Air Force (IAF), the only way out of the impasse seems to be fast-tracking the induction of the home grown, fourth generation LCATejas.The dilution of the scope of MMRCA-- once described as the mother of all defence deals—to the outright, off-the-shelf acquisition of 36 Rafale fighters from France has the IAF worried. For in its original avatar, MMRCA tender envisaged the acquisition of 126 fighters with initial 18 aircraft to be supplied in a flyway condition by the vendor bagging the contract and remaining to be assembled at the state-owned Hindustan Aeronautics Limited(HAL). The IAF has however left none in doubt that it needs more than 36 multi role medium combat aircraft. But in the ultimate analysis,the concern in IAF is that it may be saddled with the problem of maintaining a variety of squadrons of fighters of different category and configuration, imposing a strain on its limited budget.

Clearly and apparently, the Indian Defence Ministry wants the IAF to go in for Tejas in sufficiently large numbers and encourage the domestic aeronautical industry in a big way in line with the Make in India policy of the Indian Prime Minister Narendra Modi.One of the key objectives of the revised defence procurement policy of the Indian government is to reduce imports by a substantial extent and help end India’s not so pleasant reputation of being the largest importer of defence hardware in the world. On another front, the message that the Indian Defence Ministry wants to deliver to the services is that the fascination for the costly, glitzy imported defence hardware cannot go on forever.

Even so, there are divergent views on the feasibility of IAF falling back on Tejas which is notyet a fully proven fighter. Brushing aside the concern that Tejas will not fully well meet the requirements of IAF.K.Tamilmani, Director General (Aero-Systems)of the Defence Research and Development Organisation (DRDO)says “Almost all the problems will get solved in the current configuration of Tejas. There is always a scope for improvements.But there are no flight safety issues.” Incidentally, not a single accident or mishap was reported while Tejas was being subjected to a variety of qualification trials across different geographical regions of the country. However, the big worry is that whether HAL will be in a position to deliver Tejas to IAF in a time bound manner. In this context,HAL has said that it would be able to ramp up the production of Tejas to 16 a year by 2017 to meet the requirements of IAF. Even if in the immediate term, HAL manages to ramp up its production rate of 12 jets a year from the existing 8 per year,how far it will take care of the needs of the IAF, only time will tell.

And how fast India will be in position to acquire the Rafale fighter being bought under a government to government deal, there is no clue as yet. But the vexatious process of negotiations for the finalization of contract for buying 36 Rafale aircraft from Dassault aviation is expected to take its own time.For a number of tricky issues including the offset clause and technology transfer are too complex to be settled easily .As envisaged now and granting that everything moves as per the plan, the first of the Rafale fighter is not likely to land in India before 2017.Clealry and apparently, IAF would need at least six squadrons of aircraft similar to Rafale in capability to boost its operational requirements. As it is, the deal to acquire 36 Rafales was announced during April 2015 visit to Paris of the Indian Prime Minister.

IAF chief Arup Raha has nonetheless expressed concern over the delay in the schedule of inducting Tejas into the squadrons of IAF.HAL, which is being blamed by IAF for cost escalation and time overrun in delivering the fighting equipment, is planning to rope in industrial units to speed up the assembly and integration of Tejas. As it is, HALis keen on roping in about a dozen industrial units as Tier-1 and Tier-II suppliers. This strategy is seen as a supplement to HAL’s existing capability to increase production and match delivery schedule of Tejas.

“We are trying to get modules of LCA done by private industry. We have already sent RFI (Request for Information) to the industries interested in taking up this job,”said T SurvarnaRaju,Chairman,HAL.HAL would need to handhold the industrial units participating in this project till they attain maturity. In the quest to build the fighter squadron capability to 42 by 2017, the IAF is keen on inducting as many combat aircraft as possible without any delay. The two squadrons of Rafale, expected to carry a price tag of US$5-billion, will only partially make up the deficiencies faced by IAF in terms of combat aircraft capability.” I would certainly want more…at least six MMRCA squadrons,whether they are Rafale or some other alternative. But they have to be viable in terms of cost, transfer of technology and Make in India policy,” said Raha.

Certainly,the IAF would also be interested in inducting the twin-engine fifth generation Advanced Medium Combat Aircraft (AMCA) to be developed as a follow on to Tejas in sufficient numbers. But the project to develop AMCA with advanced features is yet to get mandatory sanction from the Government. This would make for the delay in the developmental schedule of AMCA.The twin engine AMCA fighter in 20 tonne class, for which a feasibility study has been completed, will not enter service until the middle of the next decade. Of course, AMCA will have features such as stealth, thrust vectoring, swing role, serpentine like air intake and use of radar absorbing composites.

The IAF has hinted that it is ready for the large scale induction of Tejas in its Mark One configuration subject to the condition that some of its features are upgraded.”We will induct them in the present shape in large numbers and not insist on the Mark-II version” said Raha. . The immediate priority is to set right the flaws in Tejas and induct it as early as possible.The development of Tejas Mark-II version for which the Government has sanctioned Rs.24310-million with a higher performance engine and multi-mode radaris expected to proceed a pace. So far, IAF is committed to inducting only six squadrons of Tejas—two squadrons of Mark-I version and four squadrons of Mark-II.Even so there is a feeling that in the context of Tejas-I meeting the immediate needs of IAF,the Mark-II version could be junked in preference to the proposed AMCA.

IAF sources point out that they are looking at two possible scenarios:of ordering more Rafale fighters or filling the gap with more indigenous Tejas and the proposed Advanced Medium Combat Aircraft (AMCA).All said and done,the IAF is looking at inducting Tejas-I with improvements in electronic warfare suite,refuelling capacity, better radar and better missiles. The present Mark-I version LCA was assessed by IAF to have57 deficiencies of which 45 have been addressed.Tejas is claimed to be superior in capability and performance to the Chinese JF-17 which is also in service with PAF(Pakistan Air Force).

Of course,Tejas has come in for criticism for cost escalation, time slippage and operational deficiencies.And there was also a motivated campaign to ground the Tejas project.But at the end of the day,Tejas has proven its flying capability and fighting punch. It may not be a “dream, fighter” that the IAF has been keen on operating. But after induction its performance can be improved in a phased manner with the feedback routinely made available by IAF. Tejas in, its current configuration, may not be in a position to meet the entire range of the operational requirements of IAF. But then as a tactical fighter, it could help IAF stay at the winning edge of the war. In fact, the Tejas development was taken up with a view to replace the fast ageing Mig-21 fighters forming a part of the frontline formation of IAF.The Mark-I version of Tejaswill have limited capability on account of the limitations imposed on by its power plant capable of generating less than 100-kN thrust.

Notwithstanding its deficiencies and shortcomings,Tejas stands out as a bold attempt byIndia to develop a state of the art fighter virtually from scratch and in the process help fill gap in Indian aeronautical technologydevelopment dynamics. The expertise acquired and infrastructure built during the process of developing Tejas could serve as a robust platform for building advanced futuristic fighter aircraft.Dr.Kota Harinarayana, who initiated the programme for the development of Tejas virtually from scratch as the Director of the Bangalore based Aeronautical Development (ADA) which was set up by DRDO to fast track the fighter development,says “Developing a fighter is far more complicated than developing a commercial aircraft. It takes time.For every fighter jet in any part of the world the time taken for research, development and production is around 25-30 years.I agree that it took a little longer but considering the fact that when the project was given a go ahead there were several sanctions,restriction and lack of infrastructure, I feel the attempt to develop the fighter aircraft was worth the while”

Meanwhile, there are plans to explore the export market for Tejas. Third world countries on the lookout for a cost efficient fighter aircraft are considered potential buyers. But then this fighter aircraft will have to prove its battle worthiness after its induction into IAF. Added to that a vibrant base for the maintenance and after sales service and spares supply would need to be created.

A small pooch to the gurus

Is ITR and STR applicable to submarines turning in submerged condition.

Also when making a turn like train or air craft does the banking angle

Tan X = velocity squared divided by radius of the turn circle arc times acceleration due to Gravity

Applicable?

From my Hydraulics by khurmi and Levit days I think but if that is so then the sub has to incline at angle of its longitudinal axis so the sailors would be inclined as well with respect to vertical?

Hi Gurus,

Below are the problem currently being faced as per someone chai wala sources inside HAL.

1.Apparently the maintainance issue has still not been resolved and won't ever be since the design is frozen . Apparently it can take more than a week just to access the radar and make repairs (for example).
2.The airforce has a requirement for 120 Km range on the radar but the kevlar radome gives just 50 Km .The quartz radome is still stuck since it needs to be flight certified which in itself is another ram kahani. Israel has offered to do the entire development by themselves (integrating the quartz radome etc).
3. A new Aesa is required as a drop in fit mostly to increase the range more than anything else.They have no clue how to sort out the cooling issue.
4.The radar and laser designator cannot target the same point simultaneously (A2G obviously).There are also many small issues with A2G operations .. Issues that makes life difficult for the pilot
5.The tejas mk2 does not exist as of now . All the funds were diverted to the tejas mk1A .
People supposed to be involved in the mk2 project are sitting around twiddling their thumbs since that now needs separate funding .
6.The naval LCA is another money pit .The russians more or less designed the undercarriage and the onshore ski jump and other test facilities.
7. Foreign consultants only show up and tell you "best practices" or how things should be done, no one ever fixes your problem for you ..
8. The LCA does have good points on the software part . However all the bugs have still not been worked out .
The airforce is totally fed up with the LCA and just want "something" absolutely bare minimum in service .THey do not want any substantial improvement in it's agility as asqr of 1993 still holds good today however BVR performance is a must .

dragon, sorry somebody has just put together a bunch of stuff from the net and cooked up a lot of things which are just BS.

>>1.Apparently the maintainance issue has still not been resolved and won't ever be since the design is frozen . Apparently it can take more than a week just to access the radar and make repairs (for example).

whoever said this needs his head examined and needs to actually see the radar placement on the LCA. If it even takes hours, it would be a huge thing. the whole set is right up there in the front of the cockpit, with easy access panels around it.
as regards maintenance issues never being resolved, as design is frozen, again cooked up stuff since Mk1A is still in the process of resolution. not all issues can be fixed but there is a reason HAL/ADA committed to 44 out of some 50 plus RFAs.

>>>2.The airforce has a requirement for 120 Km range on the radar but the kevlar radome gives just 50 Km .The quartz radome is still stuck since it needs to be flight certified which in itself is another ram kahani. Israel has offered to do the entire development by themselves (integrating the quartz radome etc).

this has been known for a while and actually israel couldn't do it themselves easily and hence we went looking for cobham.

>>>3. A new Aesa is required as a drop in fit mostly to increase the range more than anything else.They have no clue how to sort out the cooling issue.

yes sure, the israelis who have examined the LCA and Jaguar would have no idea of the design needs..

>>>4.The radar and laser designator cannot target the same point simultaneously (A2G obviously).There are also many small issues with A2G operations .. Issues that makes life difficult for the pilot

the radar is going to be replaced anyhow, so it will be certified. besides, does even the N011M+Litening work in an integrated fashion?
..

sorry but theres a lot in the above which is plain fishy, including the "Russians designed the LCA Naval undercarriage".. actually HAL did that and EADS was roped in to fix it.

I see someone like Rahul Bedi publishing this on Janes with additional mumbo jumbo masala.
The total cost of development for the LCA was to the tune of 13000 Crore Rupees(Yeah, OMFG!) or .......2Billion $. (Spread over 30 Years) *Amreeki in the distance shouts "Ashte naa, guru?" *
So yes, the cost as seen by a "Kitnaa deti hai?" person is massive.
And I would like to call BeeYess on the Russians assisting on undercarriage redesign.
Edit: Karan M is on Pole, I see. :D

Thanks Karan,

I was not sure whether there is any truth behind those allegations but thought no harm in discussing these over here.I was mostly concerned with 4 (IAF would not be happy about it ) & 5 point .MK2 is the future and cannot waste time because of funding issue.High time we understand importance of strategic programs.

Meanwhile news is LCA would be making two stop overs from Bangalore to Jamnagar and then to Muscat (Oman ) . I wonder whether it would be flying with external tanks ie LSP3 or 4 ? (as distance from bangalore to Bahrain is 3200 KM approx).

dragon, i get your curiosity and honest intent. however, please be very skeptical about some of these stories.

they just don't pass teh "smell test".. for instance, our common sense test. i.e. take 4 for instance, did IAF have dedicated radar modes for its Mirage 2000s when it used Litening to blast Tiger Hill?
So when did that become an unsolvable issue.. some chap came up with a story and then cooked more up.
Also, the entire point of getting an Israeli radar integration team (and something they are ok with) is to ensure we get end to end support for stuff like cooling etc.

similarly Mk2, it will continue for naval LCA. IAF Mk2 may/may not come, we know that. again, this dude who posted this just took known stuff and added some masala. IMHO.

Why is it always these "un-named officials" making these allegations and being quoted by DDMs? They should come out in the open if they stand by what they say. Most likely some of these "officials" may be in uniform but are not involved in the program at all and are hearing bits and pieces through their chiawallas who heard from their panwallas etc. ;) At each Chinese whisper passage someone simplifies to black/white and adds their own biases and masalas.

These DDMs, if they want to progress to true investigative journalism and do their job, need to use their press passes and gain access to people who are actually working on the program and can be named ... not some shadowy figures who may be saying things because they have other hidden agendas. The real people are pretty open (within disclosure limits) and accessible!

Dragon,

As Karan says, if somebody tells you that the radar of any fighter takes a week to get to, you can write that persons opinions off as ignorant or motivated.

By the way, I don' know about the cooling on the ELM-2052, but it is hard to believe that the Israelis "don't have a clue". Similarly, for Uttam AESA, not only do they have a clue (2.65kW), they are designing a liquid cooling system to dissipate (3kW) just in case of potential growth in power requirements.

Thakur_B wrote:LRDE has called out tender for liquid cooling system for AESA Project L-273 (Uttam). Last known the array was undergoing ground tests and the processors were incorporated on the flying testbed "Hack" and undergoing testing with the existing mechanical array.

LRDE is developing Active Array Antenna Unit (AAAU) based fire control radar for LCA Mk1 and Mk2 platform under project Uttam. The AAAU is mounted on aircraft's bulkhead with an interface frame and will be protected by radome. Additional Radar LRUs are housed in front fuselage of the aircraft behind the AAAU between station 1 and station 3 as shown in figure 1 & 2. The mounting frame has three decks of which middle and bottom deck are allotted for the radar LRUs.

AAAU dissipates 2650 watts of heat during operation and needs to be cooled with a suitable cooling system. Considering the various options available , availale space, geometry constraints, available cooling medium etc, it has been decided to go for "Liquid Cooling System" to dissipate the heat. This cooling system consists of cooling pump & flow circuits and liquid to air heat exchanger. But ADA has a qualified heat exchanger that meets the cooling requirement of AAAU that can be integrated in the aircraft. In view of the above it has been decided to develop "Liquid Circulation System(LCS)" utilising the existing heat exchanger (3.0 KW).

By the way, will you please change your username to a more human sounding name. Thank you.

@dragon "The radar and laser designator cannot target the same point simultaneously (A2G obviously).There are also many small issues with A2G operations .. Issues that makes life difficult for the pilot"

then how come it dropped laser guided bomb and fired AAM in quick succession that too in a live exercise (iron fist 2013 ) if the pilot is having so much difficulty to lase the target.

from tejas boucher " Multi role capability demonstration during
IRON FIST by simultaneous release of Laser
guided bomb, Chaff & Flare dispensation and
R73E missile within a span of 100 secs"


if both the designator and radar are of yehudi origin and still issues with A2G capability !!!

Lists LCA Tejas (2 Flying) under DRDO. Strangely AEW&C (which I believed was the EMB 145) is listed under IAF..... Is there something we dont know about the EMB145 ??

Show goes on on 21-23 Jan. LCA should depart maybe a week earlier. We might get to see some interesting practice 'naach' few days before that. Gurus Keep your cameras ready. *(Grammer Nazi edit)

Side note: LCA will be flying with some interesting company. F22, F16, Typhoon, JF17 etc etc

LCAs flying to Bahrain on their own (albeit multi-stops) carrying external fuel tanks should be an eye opener for many "range-anxiety" folks :) That would clearly cement the fact that the LCA has the reach even if one-way to all corners of Pakistan. AAR capability at FOC should further dispel such fears amongst the DDM layman.

Foreign consultants in form of OEMs/Organizations could be bounded by various export restrictions in their home markets and along with the fact that they don't want to just give away (even if boat loads of money are paid) to a potential competitor.

I think one of the ways to get around is to contract key personnels. For ex: with the kevlar radome, I am sure there will be PIOs, who would have some experience with designing & troubleshooting. Identify such people and see if they could come on board as individual subject matter experts on contractual basis. The resident phoren citizens could educate me, but I think individuals usually are not restricted like org about "knowledge transfer" to a different company. Can Govt bar the individuals from transferring any aspect including applying their previous experience to a project of a foreign company owned?

^^^

Individuals are bounded by the contract terms they signed during employment and/or at the time of exit. The more sensitive the subject matter the more restrictions in the contract. Some things like number of months/years an individual needs to wait before joining a competition, and/or various levels of non-disclosure agreements in place. Some export-restricted areas come under Federal jurisdiction and there may be additional monitoring/clearances required. Governments like the US for example don't allow their citizens to be employed by foreign government or serve in foreign armed forces.

then how come it dropped laser guided bomb and fired AAM in quick succession that too in a live exercise (iron fist 2013 ) if the pilot is having so much difficulty to lase the target.

from tejas boucher " Multi role capability demonstration during
IRON FIST by simultaneous release of Laser
guided bomb, Chaff & Flare dispensation and
R73E missile within a span of 100 secs"


if both the designator and radar are of yehudi origin and still issues with A2G capability !!!

There's a video of it somewhere iirc, Tejas dropped the lgb in a dive, popped a flair and targeted it using r 73 but the flair went out by the time the missile was launched and homed in while doing a complete 180 turn

Say, from Bhuj to Bahrain is 2K kms. A Konarak stop is half way.
But, I think LCA can cruise non-stop to Bahrain from Mumbai direct with no problems.

ref: 3k range

LCA with weapon load will have less range, obviously. The 3k range is for air show.

Meanwhile, Saurav Jha drops in with his pearls.

SP-2 is currently at the checkout stage. May start flying soon. #HAL Tejas update 1.


As we know three LCA units are headed to Bahrain. Two will fly, one on standby. #HALTejasupdate2.


Radome and IFR integration will commence soon and test units will start flying in Early 2016. #HALTejasupdate3.


HAL has been told to stop delaying an(d) put in its share for the new Tejas Mk-1A line. Orders will definitely grow over time. #HALTejasupdate4.


Tejas Mk-1A order in process. Requires a monetary rejig. Being done by the IAF #HALTejasupdate5.


Tejas MK-2 development will continue as part of a standard product improvement approach. #HALTejasupdate6.



By the way, I love this guy. He has his biases, but he is transparent about it. And he brings out real pieces of news without any sensationalism. Very few left of his ilk now. Most have conformed to the new norm. For example, I have been waiting for Shiv Aroor for his "LCA special report" for two months now! But in my purist mind, "news" is supposed to be dry, it is not supposed to be changed into a "story". Furthermore, Aroor brazenly solicits advertisement on his blog right next to his upcoming story! I know I should not single him out. The industry has changed.

But the purist in me yearns for what my grandparents and parents have passed on to me over the years: the pure joy of opening the newspaper early in the morning and reading "news". Of providing the intellectual stimulation to start my day, and discussion material for my evenings. I remember I used to read the editorials to learn the language. Today's editors are busy adjusting ads!

Shrugging off my romanticism is probably the only way out. Or probably, we should cumulatively find a way for earnest journalism to succeed over this ubiquitous sensationalism. At least create a niche for it.

^^ You said it. Our journalists behave like activists. Idealogy trumps substance.

Aroor has always been a sensationalist con job artist. I still remember his "exclusives" in the Express. A lot of verbiage to disguise dodgy claims and assumptions. IMO, he and Sengupta are birds of a feather.

Well said Indranilroy sahab. IMO, Journalism has changed world over for the worse. The quantity has increased but quality has decreased overall. It seems most of it is a recycling of rehashed materials originating from few sources. Often times recyclers tend to alter to make it more "catchier" i.e. sensationalization, opinioniated, truncated into sound bites. Probably necessary to standout for their target audiences and make a quick buck in the process. Not much money to be made in in-depth well-researched pieces anymore. More and more people don't seem to have the time/patience to read them and expect easily digestible shorts where the gaps can be filled by one's inclination. Maybe this has lead to the rise of people not discussing merits but instead arguing in parallel sound bites--after all they can be backed up by "sources" in whatever form and substance they maybe in.

Bhai sahib,

Interact with a few "journalists" in person. Ask a few honest kweshchens of them. Any of them. Your favorites and the ones favored here. It is an eye opener and I say that with both cpnfidence and broad and varied actual experience. I dont know of the past but now everything that is fought over here is nothing but a saas bahu drama in prose. The obscure message boards *sometimes*, *rarely* leak some truth to the discerning but social media too is just as manipulated and censored. We live in a managed leper colony, a fools paradise.

If the orders for LCA Mk-1 are still IOC 20 + FOC 20 + Mk-1A 108 then still there is hope for LCA but if we going to jump directly to Mk-1A as being indirectly suggested in many News Articles then LCA is Arjun ie Scre*ed.

Nice. And gratifying to hear a name like Group Captain Rangachari ! Quite appropriate.

A name like that brings to mind the kind of images that dad being an old style Triplicane Madrasi always talked about. For him, his first impressions of Kirkate was the bowling of THE Rangachari , the fastest bowler in test cricket in India of his days, a bowler sporting an orthodox "kudumi" and dad always talked about how he clean bowled an English batsman (Hutton ?) who was on a rampage and broke his middle stump.

Well, lets hope that the Tejas too clean bowls the opposition with many more Rangacharis, Nayudus, Mankads and others at the helm.
