Does anyone have the radius they took for the turn or needs to be calculated.

Less time and radius! does it depend on the pilot or any other factors.

Has there been any news on the Kaveri? Given that the MK2 request has been made, it would be a better if we have an indigenous engine. Has there been any advancements on the design issue in the Kaveri? Is the development still active? If it is, I think it would be a good idea to give it its own dedicated thread.

Tejas IOC gets delayed again

India’s Leading Newspaper “The Hindu” recently reported that the, Initial operational clearance (IOC) of Tejas may be Postponed on the suggestion of the Indian Air force , Suggestion was put forward by IAF in the last “ Monthly Review Meeting “which was attended by the ADA and HAL officials ,Re-scheduling was suggested due to lack of Test flights and slow progress on the integration of the MMR Radar on the Tejas PV-3 which is holding back the Weapons Testing ,To Further understand possible reasons for this delays ,we are having a interview with the Vinayak Shetti who is developer of the www.lca-tejas.org ,A site which is provides lot of information on the Tejas fighter aircraft

IDRW: Will Re-scheduling of IOC hurt the Tejas Program?

VS: It will delay the induction of jet in the IAF; Program has already suffered lot of Delays further delays will only have adverse effect on the whole program. It will also affect Tejas MK-II Program

IDRW: Lack of Pilots and Lack of aircrafts have been blamed for Low sorties, what’s your take on that?

VS; Regarding Lack of Aircrafts all blames goes to Hal, they took more then two years to setup Production line for Tejas even when the funds where provided to them, in last three years only two LSP (Limited series Production) Tejas have taken to air, and Tejas Lsp-3 is already one year behind schedule. As per the original Schedule at least 5 LSP should have taken to sky by mid 2009 but Slow pace of work by Hal on Tejas Lsp has kept the whole program waiting for the new aircrafts. Coming to lack of pilots it’s the responsibility of IAF to see that enough pilots are deputed to NFTC for the Tejas Programs, Lack of pilots is not a major issue here but lack of Aircrafts certainly is.

IDRW: HAL has blamed ADA for not providing crucial computers to be integrated for LSP-3 which resulted to delays.

VS: Many of the crucial components and avionics of Tejas have still not hit the production line and still manufactured under various labs which is causing delays in their manufacturing.

IDRW: Why are Avionics and other crucial components have not yet hit the Production line?

VS: Possible reason could be that Many of the current Avionics of the Tejas are for over haul and New Avionics are been designed by ADA, Each Aircraft have some new addition to its avionics system and after two Major change in its over all avionics ,Tejas will See one more re-working on Avionics before it hits production line.

IDRW: What are the other possible issues which are delaying LSP-3 which will have first on-board Radar?

VS: There seems to be some glitches with the software, but now it seems most of the issues have been sorted and first flight hopefully will take by end of this year.

IDRW: You earlier mentioned Tejas MK-II, when are the possibility of its first flight?

VS: As per the original Schedule first flight is expected with in Next four years, but with little work on MK-II program done yet it seems we will see further delays there to, since lot of work has to be done in that front to, but the slow approach of ADA and HAL will not help the MK-II program at all.

IDRW: Recently IAF rejected proposal of JV on Kaveri Engine with French firm and GTRE, is this Dead end for Kaveri Engine?

VS: Not yet, IAF is still open to local Research in the development of the Kaveri engine, French could have offered us some TOT on certain Parts of the engine but could have kept critical Parts out of TOT Deal which might have prompted IAF to reject their proposal, since Kaveri has been detached from the Tejas Program it is advisable to work locally to further develop the engine.

IAF suggesting flight worthy engine for LCA: Antony


New Delhi, Aug 3 (PTI) Government today said DRDO has proposed to co-develop and co-produce an upgraded version of Kaveri engine with French engine manufacturers Snecma for the Light Combat Aircraft (LCA) but the IAF has suggested that a proven and flight worthy engine to be put on the aircraft.

"DRDO has offered to co-develop and co-produce 90 KN thrust class of upgraded Kaveri engine with Snecma to meet the operational requirements of LCA within 48 months of due date of project inception," Defence Minister A K Antony said while replying to a Lok Sabha query.

"Indian Air Force (IAF) has suggested a proven engine that is already in production and flight worthy for meeting immediate requirements," he added

'Indigenous' Tejas fighter to get 'foreign' engines for power

NEW DELHI: India's quest to develop its own multi-role supersonic fighter, the Tejas Light Combat Aircraft (LCA), continues to falter even after
25 years. Its heart also needs a foreign transplant surgery now to function properly.

The defence ministry has asked two leading aeroengine manufacturers, General Electric (US) and Eurojet Turbo GmbH, to submit their bids within three months to supply 99 engines, with an option for 49 more, for the Mark-II version of Tejas.

With GE F-414 INS5 and EJ-200 being the engines in contention, eight will be bought off-the-shelf, while the other 91 will be manufactured in India under transfer of technology in an estimated $600 million contract.

This comes after the indigenous Kaveri engine failed to pass muster even after two decades of development at a cost of Rs 2,839 crore. While the first 20 Tejas will be powered by GE-404 engines, the next six Tejas Mark-II squadrons (16-18 jets in each) will have the new more powerful engines.

Sounding the death knell for Kaveri, IAF has shot down the offer of Defence Research and Development Organisation (DRDO) to co-develop and co-produce the "90kN thrust class of upgraded Kaveri engine'' with French company Snecma to meet Tejas' operational requirements, defence minister A K Antony told Parliament on Monday.

DRDO contended the modified Kaveri engine would provide "comparable thrust throughout the flight envelope of Tejas''. Moreover, it would require minimum changes in airframe to integrate this engine without affecting the weight and configuration of the single-seater fighter.

"IAF, however, has suggested a proven engine that is already in production and flight-worthy for meeting immediate requirements. The RFP (request for proposal) has been issued to reputed engine manufacturers,'' said Antony.

Incidentally, the GE-414 and EJ-200 engines power the American F/A-18 and Eurofighter, respectively, two of the six jets in the race to bag IAF's $10.4 billion project to acquire 126 "medium'' multi-role combat aircraft (MMRCA).

IAF, incidentally, has ordered only 20 Tejas till now, apprehensive as it is of its capabilities since the fighter's final operational clearance (FOC) will come only in December 2012 at the earliest.

Antony declared that high-level reviews of the Tejas project were being conducted regularly by IAF chief and deputy chief to ensure it's completed in time.

Hindustan Aeronautics Ltd, Aeronautical Development Agency and DRDO have, of course, faced a lot of flak for the huge delays.

Initiated as far back as 1983 at a cost of Rs 560 crore to replace ageing MiG-21s, the LCA project costs have now jumped to Rs 5,489 crore. The figure may well cross the Rs 10,000-crore mark by the time the fighter is fully ready.

IAF is certainly keeping its fingers crossed, grappling as it is with a depleting number of fighter squadrons, down to just 32 from a sanctioned strength of 39.5.

The force is banking upon the "air dominance'' Sukhoi-30MKI fighters, with 230 of them being contracted from Russia in deals worth around $8.5 billion, to fulfil its need for "heavy-weight'' fighters. The MMRCA will take care of the medium-weight category. Tejas, in turn, is slated to plug the light-weight fighter gap in the combat fleet.

Flight testing of Tejas [FONT=Arial, Helvetica, sans-serif] [/FONT]
[FONT=Arial, Helvetica, sans-serif]18:55 IST [/FONT] /LOK SABHA/

Taking into account certain changes in the objectives proposed by Indian Air Force, the second quarterly review held in March 2007 by the Empowered Committee chaired by Chief of Air Staff (CAS) have recommended the date for Final Operational Clearance for Light Combat Aircraft (LCA) Tejas as December 2012.

To complete the project in time, a high level review is being conducted by the CAS once in every quarter and by the Deputy Chief of Air Staff once in every month.

This information was given by Minister of Defence Minister Shri AK Antony in a written reply to Shri Adhalrao Patil Shivaji in Lok Sabha today.

HAL Tejas timeline

1980s
1983
DRDO obtained permission to initiate a programme to design and develop a Light Combat Aircraft
1984
Government of India set up Aeronautical Development Agency ADA in 1984 as the nodal agency for managing and developing the LCA.
1985
IAF submits Air Staff Requirements (ASR) for LCA in October 1985. This was initiated by the then Air Chief Marshal Idris Hassan Latif.
1986
Programme to develop an indigenous powerplant (engine) was launched at GTRE.
1987
Project definition commenced in October 1987 with French Dassault Aviation as consultants.
1988
Project definition completed in September 1988.
1989
Government review committee expresses confidence in LCA programme. It was decided that the programme will be carried out in two phases.

1990s
1990
Design of LCA was finalised as a small delta winged reverse static stability aircraft.
Phase 1 of the development was commenced to create the proof of concept system. Financial problems within India prevented full scale operations from starting.
1993
Full funding started from April 1993 full-scale development work for phase 1 started in June.
1994
Development partnership sought from China.
1995
Technical assistance sought with Israel in critical bottle-neck areas.
First technology demonstrator, TD-1, rolled out on 17 November 1995 and was followed by TD-2 in 1998. However, technical problems in flight control systems and structural deficiencies plagued the prototypes and they remained grounded.
1997
Multi-Mode Radar (MMR) for LCA design work started at HAL’s Hyderabad division and the LRDE.

2000s
2001
Development assistance sought from Snecma on the Kaveri engine.
4 January - LCA’s maiden flight successfully completed by Technology Demonstrator TD-1 , on , 2001. Prime minister Atal Bihari Vajpayee renames LCA as Tejas.
2002
MMR system was reported to be not working as per the criteria laid down in requirements.
2006
13 May - The PV-2 went supersonic for the first time
14 May - The PV-2 went supersonic again, but this time in a weaponised state (i.e., carrying weapons such as missiles and an internal gun).
1 December - The PV-3 flew for the first time for 27 minutes at an altitude of 2.5 km and at a speed of Mach 0.8. The PV-3 was equipped with a more advanced pilot interface, refined avionics and higher control law capabilities compared with the previous versions.
2007

China/India discuss LCA project
VEENA SINGH/ NEW DEHLI
CHINA AND India have
entered preliminary discussions
over co-operation on die latter's
Light Combat Aircraft
(LCA) project, with a high-level
Chinese delegation visiting the
country at the end of July for talks.
India has been desperately
seeking partners for its long-running
LCA programme to replace
its ageing Mikoyan MiG-21s, as
project costs have escalated.
Approaches to Western manufacturers
have so far proved fruidess.
A Chinese delegation, led by
Zhang Yang-Chong, vice-president
of the Aviation Industries of
China, led a ten-strong delegation
to Bangalore to meet die LCA
programme director Kota
Harinarayana.
India had previously
approached Saab of Sweden and
British Aerospace as potential
partners for the LCA programme,
but neither company appears willing
to gamble on die project.
China has a long-term requirement
to replace its Xian J-7
(MiG-21) and Shenyang J-6
(MiG-19) in the attack role, with
the LCA providing a potentially
attractive option.
Informed sources, however, suggest
that while collaboration
between China and India on a civilaircraft
programme is credible,
military collaboration is more
problematic.
China has also expressed an
interest in developing jointly a
lOO-seat regional airliner with
Hindustan Aeronautics and Soudi
Korea. There is doubt, however,
about whetJher this projected project
will come to fruition. •

That is an article that you are supposed to read and then decide not to post. And it requires common sense and is a waste on time and bandwidth.

What a sad joke is this. Imagine one of the country against whom te LCA wi bevused is going to be co developed?
Right, we need more SSBNs. Maybe India can co develop the Jin class and also help China with reverse engineer the Phalcon AWACS.
Was the writer of this article even thinking?

I really think we should decide the operational engine first and then go in for mach 2 of tejas. Ej 200 lacks thrust. but comes with more tot i hope.

I think its good opportunity for India we should deal with full TOT.
It will boust indian defence technology and help in R&D and for our future defence development
The important part for a engine is its metallurgy. I don't think we us would have problem giving us the metallurgy provided we pay for it. It is not something that is unique through out the world. However the point is do we need ToT. Licanace production like AL-31 will also do.
Getting ToT of other engines doesnot helps in R&D for our engine.
