Navy backs Tejas with Rs 900 cr

Talk to navy fighter pilots about their air force counterparts and you cannot miss the message: air force pilots are pussycats… real fighter jocks fly from ships!

One of the most breathtaking sights in military aviation is a modern fighter landing on an aircraft carrier deck. Flying in at over 250 km per hour, it must halt within 100 metres, one-tenth the distance available to most land-based fighters. The pilot aims at a cable stretched across the landing area; a tail hook on the fighter’s rear fuselage catches the cable, effectively dragging the aircraft to a halt before it runs out of landing deck, subjecting the pilot to a deceleration 4.5 times the force of gravity.

It is called a THUMP-BASH technique. As the fighter thumps down onto the deck, the pilot bashes forward his throttle, revving up the engines to full power. It seems a crazy thing to do when trying to halt really quickly, but there’s a reason: if the tail hook misses all three arrestor cables, the fighter must have the power and speed to get airborne again before the end of the flight deck.

To hit the arrestor cables accurately, the pilot must descend steeply, hitting the deck twice as hard as his air force counterparts, who enjoy the luxury of levelling out at ground level, descending slowly till the wheels touch the runway.

“An arrested landing on an aircraft carrier is actually a controlled crash,” naval flight instructors invariably warn their cadets.

If it takes a Top Gun pilot to pull off such landings, it takes a superbly engineered aircraft to repeatedly absorb the stresses of these controlled crashes. The naval variant of India’s Tejas Light Combat Aircraft (LCA) is poised to enter this challenging playing field. And its prospects have been boosted by the Indian Navy’s commitment to indigenisation.

Business Standard has learnt that the navy has okayed the placement of an order for six Naval LCAs. At an approximate cost of Rs 150 crore per aircraft, that will provide a Rs 900 crore infusion into the Naval LCA programme.

That investment in the Tejas programme is rooted in the navy’s plan to operate both light and medium fighters off its aircraft carriers. The Naval LCA will supplement the heavier Russian MiG-29K, which has already been ordered from Russia. The Indigenous Aircraft Carrier (IAC), being built at Cochin Shipyard, Kochi, has been designed with a separate aircraft lift and maintenance facilities for the LCA, in addition to facilities for the MiG-29K. That has linked the development of the Naval LCA with the construction of the IAC, which is expected to join the fleet by 2014.

But the LCA programme faces a bottleneck in choosing a new engine. Two uprated engines — the General Electric GE-414 and the Eurojet EJ-200 — are currently being evaluated, but will be supplied only by 2013-14. And only with the new engine will the LCA have the power to get airborne from an aircraft carrier.

P S Subramaniam, the Director of the Aeronautical Development Agency, which coordinates the LCA programme, explains: “We will fly the Naval LCA with the current GE-404 engine to test its flight characteristics, and whether its structural strength is sufficient for aircraft carrier operations. After the LCA is fitted with a new, more powerful engine we will take the next step of operating from an aircraft carrier.”

Meanwhile, a major shore-based test facility is coming up at INS Hansa, in Goa, which replicates an aircraft carrier deck on ground, complete with arrested recovery and a ski jump for take off. This facility, which is expected to be operational by October 2011, will be used for certifying the Naval LCA before actually flying off an aircraft carrier. This will also be used for pilots’ training and for training maintenance crews.

The Migs that are ordered so far are meant for INS Vikramaditya and not for IAC, so is it a mistake, or will the 16 Migs be all fighters on INS Vikramaditya?

 

[k7x]

Both IAC and Vikramaditya will carry Mig 29 & LCA. In addition to that they will have some ASW helis.

LCA for Navy is really significant as it is must in our learning curve.

$30 million is really cheap for an aircraft operating out of carrier.also Navy has indicated that it will induct 40 LCA. for both AC as well as a few shore based training.

when IAC 2 and 3 are built probably they might go for some more.

I think for IAC-2 india will go for mca or fgfa naval version. or may be f-35c

That's what I meant the article says these are for IAC (btw it was reported that only one Vikrant class carrier will be build and the next one will be a bigger carrier - IN discussion thread), that would mean no N-LCAs for Vikramaditya.
I doubt the number of 40 is still actuall, because even if Vikramaditya gets 6 too, there won't be 28 shore based just for reserve and training. Also don't forget that the Sea harriers was upg to serve till 2020 too!
Btw the $30 million unit cost is imo a good price, if you keep in mind that this is the price of the MK2 version, with further changes to be carrier capable. That means IAF LCA MK2 will cost less and the MK1 version could really come at prices of around $20 million each.

US puts Lockheed off Tejas flight path

Ajai Shukla / New Delhi September 28, 2009, 0:18 IST



Déjà vu for the US giant, as queries land at the eleventh hour.

The US government is, for the second time, squeezing American aerospace giant Lockheed Martin out of an important contract related to India’s Tejas Light Combat Aircraft (LCA).

Business Standard learns that Lockheed Martin, selected in June as a consultant for developing the Naval version of the Tejas, was given 90 days to obtain the clearances it needed from the US government. But now, with time running out, Washington has sent Lockheed Martin a list of questions about what assistance the company will provide.

Senior officials from Bangalore-based Aeronautical Development Agency (ADA), which manages the Tejas programme, say they will not delay the naval version any longer. ADA has recommended to the Ministry of Defence that another consultant be chosen. It has put forward the names of France’s Dassault Aviation, and European consortium EADS.

For Lockheed Martin, this is déjà vu. In 1993, it was selected to partner ADA in developing the Tejas’ high-tech flight control system (FCS). But after India’s nuclear tests in 1998, Washington ordered the company to terminate the partnership. India eventually went it alone, developing the world class FCS that is on the Tejas today.

Lockheed Martin is still fighting to salvage the situation. The company told Business Standard, “We are continuing our dialogue with the Aeronautical Development Agency and the US Department of Defense and are hopeful we will be able provide the consultancy desired by ADA on the Naval LCA.”

But the decision now lies in the hands of V K Saraswat, scientific advisor to the defence minister.

Lockheed Martin’s current situation replicates that of Boeing, which was front-runner for the air force Tejas consultancy. But earlier this year, after the US government failed to grant Boeing a clearance (called Technical Assistance Agreement) in time, the defence ministry awarded EADS the contract. The European consortium obtained the sanctions in time and is now working with ADA.

Foreign consultancy has been sought by ADA to introduce the Tejas into service without further delay. The air force Tejas, a single-seat, single-engine fighter, is at an advanced stage of testing. The naval Tejas, being developed around the twin-seater air force trainer, will take to the skies by mid-2010. But it will fly off an aircraft only in 2014, after getting a new, more powerful, engine. That is about when the Indigenous Aircraft Carrier, being built in Kochi, will join the Indian Navy.

The immediate challenges before the naval Tejas — which the consultant will help to resolve — include strengthening the undercarriage to absorb the high impact of landing on aircraft carrier decks, fitting an arrestor hook at the tail of the aircraft to bring it to a quick halt after landing, and adding a flap on the front edge of the wings to slow the landing speed by almost 150 kmph.

In addition, the naval Tejas needs a fuel dump system, in case of an emergency just after take-off. The take-off weight of a Tejas, with full weapons load and fuel, is 12.5 tonnes. But for landing back on an aircraft carrier, it must be less than 9.5 tonnes. In an emergency, 2 tonnes of weapons and external fuel tanks will be instantly shed, but a system must be built in for jettisoning another tonne of fuel from the fighter’s wing tanks.

None of the US Navy’s most successful carrier-borne aircraft — the F-4 Phantom, the F-14 Tomcat and the F/A-18 Hornet — was built by Lockheed Martin. Despite that, ADA believes Lockheed Martin’s experience in designing the futuristic F-35 Lightning Joint Strike Fighter qualifies it as a consultant.

“All the earlier US navy aircraft had two engines, giving them the weight and strength to support a tail hook,” explained P S Subramaniam, the director of ADA. “But Lockheed Martin has designed the F-35 Lightning, which is a single-engine fighter with a tail hook.”

Dassault’s Rafale fighter and EADS’s Eurofighter Typhoon are both twin-engine aircraft.

Indian Navy Orders Six Naval Tejas LCA Fighters; Infuses Rs.900 Crore in Programme
Dated 20/9/2009


Indian Navy has okay-ed the placement of an order for six Naval Tejas Light Combat Aircrafts (N-LCA). At an approximate cost of Rs 150 crore per aircraft, this will provide a Rs 900 crore infusion into the Naval LCA programme.

That investment in the Tejas programme is rooted in the navy's plan to operate both light and medium fighters off its aircraft carriers.

The Naval LCA will supplement the heavier Russian MiG-29K, which has already been ordered from Russia. The Indigenous Aircraft Carrier (IAC), being built at Cochin Shipyard, Kochi, has been designed with a separate aircraft lift and maintenance facilities for the LCA, in addition to facilities for the MiG-29K.

Kaveri jet engine finally poised for first flight

After 20 years in the making, the Kaveri jet engine will finally take to the skies. In 1989, Dr Mohana Rao, then a junior technician at the Gas Turbine Research Establishment (GTRE), Bangalore, immersed himself in the ambitious Kaveri programme, which was designing a jet engine for the Tejas Light Combat Aircraft. After pushing the Kaveri through two decades of heartbreak and achievement, Dr Rao is now the Director of GTRE. And his baby, the Kaveri engine, is ready to fly.

This week, a fully built Kaveri engine will be transported to a testing facility outside Moscow called the Gromov Flight Research Institute. Here, a giant IL-76 aircraft will have one of its four engines replaced with a Kaveri. Russian and GTRE experts will then evaluate the Kaveri’s performance while the IL-76 flies.

Before the actual flight tests, Russian experts at Moscow’s Central Institute of Aviation Motors will run ground checks on the Kaveri’s performance, in conditions that simulate altitudes up to 15 kilometers (49,200 feet).

Business Standard visited the Kaveri ground test bed at GTRE, Bangalore, where Russian experts are finishing “pre-acceptance checks” on the Kaveri engine that is headed for their facilities in Russia. The giant turbofan engine, suspended from a ceiling bracket, was being revved up gradually. As it roared to a deafening crescendo, engineers monitored the Kaveri’s power output, watching carefully from behind a bullet-proof glass window.

“The Kaveri’s development is complete”, confirmed Dr Mohana Rao, “In ground testing at GTRE it met the performance parameters laid down in 1998. The next step is to confirm that it performs during flight. A 50-person GTRE team will travel with the engine to Moscow and participate in the flight trials over the next 3-4 months.”

India has no facilities for altitude-testing and flight-testing jet engines. GTRE estimates it will take several hundred crore rupees to create such test facilities in India. Meanwhile, each test campaign in Russia costs Rs 50-60 crores.

For the DRDO (GTRE is a DRDO laboratory) even a successful Kaveri flight will be a bittersweet end to one of India’s most savagely criticised development programmes. A measure of success, on the one hand, in an ambitious technological leapfrog to building a modern jet engine, something only a few countries can do. On the other hand, the Kaveri has failed to provide an engine for the Tejas, even after spending Rs 3000 crores.

“The reason was two-fold”, explains Mohana Rao. “The Kaveri turned out 15% heavier than we planned. From the planned 1100 kg, its final weight has gone up to 1265 kg.”

Meanwhile, the Tejas fighter also turned out heavier than planned, demanding a more powerful engine; the Kaveri’s maximum thrust of 65 Kilo Newtons (KN) is simply not enough. The air force has chosen American GE 404-IN engines, which produce 80 KN at full power, to power the first 20 Tejas fighters. And subsequent Tejas will get about 95 KN of thrust from a new-generation engine: the General Electric GE-414 and the Eurojet EJ200 engines are currently being evaluated.

But GTRE is undeterred, having produced a high-tech turbofan jet engine in a country that has never produced even a motorcycle or car engine. “We need more thrust without increasing the size of the engine”, says Mohana Rao. “That means getting better technologies from a more experienced foreign partner. We have chosen (French aero-engine major) Snecma. The Defence Ministry has approved the tie-up.”

Business Standard has learned that Rolls Royce, and General Electric declined to partner GTRE, apparently unwilling to part with cutting-edge technology. US major, Pratt & Whitney, was willing only to provide consultancy. With only Russia’s NPO Saturn and Snecma in the game, the MoD has opted for Snecma.

Naval LCA: US puts Lockheed Martin off Tejas flight path


The Lockheed Martin JSF-35 Lightening, which will also operate off aircraft carriers. The US company was to help India with the Naval Tejas, but Washington has not given clearance.

India May Use Russian Engines For LCA​

India is seriously considering to use the Russian 33/RD-33MK engines for the homegrown Light Combat Aircraft, as it already used the Indian Air Force [IAF] fleet of MiG-29 aircraft.

A high level Indian military delegation comprising of Defence Production secretary and Chairman of Hindustan Aeronautics Limited (HAL) Ashok Nayak recently visited a Russian ‘Chernyshev’ plant where RD-33/RD-33MK engines for MiG-29K and MiG-35 are being manufactured.

As per an agreement signed between India and Russia, the license production of RD-33 Se.3 engine will happen in India as well as transfer of technology. Officials said that only the first 20 to 40 aircraft will be manufactured with imported of-the-shelf GE-404 engines.

The RD-33 MK engine has been deemed unique since it operates well on any AoA (angle of attack).

“India would benefit if it chooses the RD-33MK engine”, said a senior Indian Air force official, adding that this is because of the unification it will receive because of the common engine logistics it will achieve in the indigenous Light Combat Aircraft (LCA), MiG-29, MiG-29 MK and possibly the MiG-35. The serial production line for RD-33 class engine is already under construction in India. And after India pays transfer of technology amount for the RD-33 ser. 3 engine, it will not have to pay a double sum for the RD-33 MK engine.

The RD-33 series 3 is an upgraded version of the RD-33 powerful RD-33 turbofan engine with thrust vectoring for MiG family fighters. The engine provides superior maneuverability and enhances the fighter’s performance in close air engagements.

In 2005, Russia signed a $250 million deal with India to modernize engines for the MiG-29 fighters of the Indian Air Force. According to the terms of the deal, HAL will make 120 RD-33 series 3 jet engines at its Koraput plant for the upgrade of MiG-29 fighters. The contract will enable HAL to master the assembly of the RD-33 jet engines and use the experience in the assembly of next generation jet engines.

As for the delays in the development of fully indigenous ‘Kaveri’ engine for HAL’s LCA fighter and other IAF aircraft, it is only forcing India to keep an eye out for a powerful engine for upgrading LCA. The currently installed GE404 doesn’t fulfill the IAF specification and is not powerful enough for Navy LCA variant. The other engines in the market that fit the bill are the American GE414, British-EU EJ200 and Russian RD-33MK who stand a chance to be chosen as the LCA mark 2 engine solution till the indigenous ‘Kaveri’ engine is ready.

I am not an engineer but
Does the Russian engine give the LCA to trust vectoring capability ?

If this is the case then India should choose the RD-33mk for domestic production.

It would no doubt also be the cheapest option and have commonality with the already in fleet Mig-29.

but it will make lot of changes in dimension and iaf did not issue rfp for rd-33 only 2 co. involve in this ge for ge414 & euro jet for ej200.

 

[Sapper]

but it will make lot of changes in dimension and iaf did not issue rfp for rd-33 only 2 co. involve in this ge for ge414 & euro jet for ej200.

If India manages to acquire GE414 for LCA, it will be a real boost for the LCA program because it will not only increase the performance (payload and manouvering) of the LCA but also will provide LCA with an engine whose RAM (reliability, availability, maintainability) will be much higher than any option of Russian or Indian origin. Also GE414 is a proven engine for maritime operartions, so LCA induction into Navy will be far more easier.

I have some doubt about this news, the RD 33MK offers only 90kN thrust and the last reports says 95, or more is what IAF wants. Also its an old gen engine, whereas the EJ 200 offers latest techs that would help us way more in indigenous developments. Btw the RD 33 MK could be used with TVC on LCA yes, but TVC are on offer with EJ 200 too.

EJ-2000 Has TVC, Then why would they not include that in the Euro fighter it self.

IF what you say is true then IAF has one more reason to go for the a TVC capable Typhoon which will use the same engine as the LCA-Mk1
