DRDO looks beyond HAL for Tejas production


Ajai Shukla / New Delhi March 24, 2011, 0:59 IST
Over the last two decades, Hindustan Aeronautics Ltd (HAL) and the DRDO's Aeronautical Development Agency (ADA) have cooperated closely in developing the Tejas Light Combat Aircraft (LCA) to replace the ageing MiG-21s of the Indian Air Force. Now, with 40 fighters on order for the IAF's first two Tejas squadrons, ADA is pushing HAL to outsource more of the Tejas' production, including to the private sector, to boost production to the levels needed by the Indian Air Force (IAF).
A high-level HAL team is touring the production facilities of the world's three biggest fighter manufacturers — Boeing and Lockheed Martin in the US; and Eurofighter in Europe — to examine how Tejas' production can be raised from the eight fighters per year that HAL's Tejas production line in Bangalore will start building next year. The IAF will eventually need 120-140 Tejas, while the Navy will require another 20-40 fighters.


The DRDO aeronautics chief, Prahlada, who also oversees ADA, told Business Standard, "We have asked HAL to find a way to step up Tejas production. They should look for alternatives, like more outsourcing, or setting up joint ventures [to build sub-systems of the Tejas]. This will also help HAL to grow. But each agency knows its own problems best"¦ only they know where the shoe pinches! So, HAL knows best how to fix their problem."
HAL, however, blames the slow production of Tejas fighters on the IAF's placement of piecemeal orders. "We are also responsible to our shareholders. With an initial order for just 20 Tejas fighters, how much money could we have realistically invested in a production line?" asks P Soundara Rajan, HAL's director, corporate planning and marketing. "So far, future Tejas orders of 100-120 more fighters are only plans. When an order is actually placed, we will be justified in upgrading our production line to produce more aircraft. Outsourcing to industry is something that we are already doing."
Currently, HAL is building 40 Tejas fighters for the IAF, the initial IAF order of 20 fighters doubled recently with a second order. While HAL builds these 40 Tejas Mark I fighters, ADA will develop the Tejas Mark II, replacing the existing GE-404 engine with the more powerful GE-414 engine that powers the Swedish Gripen and the F-18 Super Hornet aircraft. ADA plans to develop the Tejas Mark II by 2014 and begin production the next year.
Behind the Tejas' slow production rate is the fact that HAL simply has too much on its plate. The Aircraft R&D Centre (ARDC), the HAL department that has built the first 15 Tejas prototypes, is simultaneously developing the Tejas Mark II; the Sitara Intermediate Jet Trainer (IJT); the Indo-Russian Fifth Generation Fighter Aircraft (FGFA); the Indo-Russian Multi-Role Transport Aircraft (MRTA).
"Each Tejas is built individually, with the ARDC tweaking the design to incorporate multiple improvements and changes. Once the Tejas goes into serial production, like the MiG or Sukhoi-30 fighters, ARDC will have less work. But, presently, ARDC is highly loaded"¦ and there is competition for attention and priority," say HAL sources.
Despite that, there is no proposal for a second Tejas production line. The Ministry of Defence (MoD) has nominated HAL as the DRDO's only production agency for aircraft. But the DRDO believes the growing number of projects will leave no choice but to locate a private sector partner for building aircraft, a field monopolised since independence by HAL.
"The earlier (the MoD finds an alternative) the better it will be because, in a country as big as India, with so many ongoing aircraft development programmes, we need at least two integration agencies. Preferably one government one private"¦ this will lead to competition, better productivity, and the spreading of risk," says Prahlada.
While ARDC builds the last two Tejas prototypes, HAL has already begun work on the first of the 40 Mark I production fighters. Meanwhile, ARDC is completing the first naval LCA, which is designed to operate off aircraft carriers. The navy is likely to ask for a limited series of eight LCAs, which will also be built by ARDC.

Designers insist Tejas will belie all sceptical questioning

With the Tejas Light Combat Aircraft (LCA) entering service with Indian Air Force squadrons, the designers of this indigenous fighter have explained why they believe this will be the world's premier light fighter.

The Tejas Mark-II, to be developed by 2014 and roll off production lines by 2018, will perform 40 per cent better than the current fighter. After which would come the Advanced Medium Combat Aircraft, the AMCA, which the Defence Research and Development Organisation (DRDO) says will be a "fifth-generation plus" fighter, more formidable than anything flying today.

In an exclusive interview with Business Standard, P Subramanyam, director of the Aeronautical Development Agency (ADA), which is developing the LCA and the AMCA, responded to IAF criticism that the Tejas was not yet a world-class fighter. He said the Tejas Mark-I, still being flight-tested, had been flown to just 85 per cent of its full capability. The Tejas Mark-II — in which a more powerful GE-414 engine will replace the current GE-404 engine — would perform another 15 per cent better.

"The Tejas Mark-I will expand its performance envelope to its full capability by end-2012. And, a major performance boost will come from the Tejas Mark-II's new GE-414 engine, for which we have signed a $700-million (Rs 3,135 crore) contract to build here in India. The Mark-II will outperform the Mark-I by about 15 per cent in the key aspects of take-off run, rate of climb, acceleration, and turn rate. Most of this would come from the higher thrust of the GE-414 engine. Another two-three per cent benefit would come from better aerodynamics"¦ since we will re-engineer the fighter to accommodate the new engine. That overall 35-40 per cent improvement would make the LCA the world's premier light fighter," says Subramanyam.

The Tejas Mark-I is scheduled to obtain Final Operational Clearance by end-2012. A fighter is granted FOC when ready for combat missions, with all its weapons and sensors fitted, integrated and tested. The IAF worries that the Tejas, already long delayed, might not obtain its FOC on schedule.

Meanwhile, ADA designers are working on the Tejas Mark-II, which Subramanyam says will fly by 2014, enter production by 2016, and obtain FOC by 2018. "Besides re-designing the airframe to accommodate the GE-414 engine, ADA will also grab the opportunity to upgrade key electronics, especially the flight control computer and some avionics, so that the Mark-II is a cutting-edge fighter when it enters service," says the ADA chief.

'No fancy plan'
Brushing aside apprehension of further delay of the kind that has dogged the Tejas programme, Subramanyam insists, "Our design timeline is realistic. The main sub-systems of the Tejas Mark-II will remain unchanged, except for electronics components. So, the Mark-II will not need extensive flight-testing, as most of its sub-systems will have already been test-flown on the Mark-I."

ADA designers also say "maintainability" of the Tejas has already been established. This key attribute relates to how quickly and easily technicians can service and repair the fighter and, therefore, how quickly it can get out of a hangar and into combat. Of 200 "requests for action" — suggestions from IAF pilots and technicians for design changes that would ease maintenance — most have already been implemented. Just 12-15 remain for implementing in the Mark-II.

The Tejas programme will provide the springboard for the ADA's next project, a more heavily armed and capable fighter. Even as Hindustan Aeronautics Ltd and Sukhoi, the Russian aerospace giant, jointly develop the Fifth Generation Fighter Aircraft (FGFA), ADA will go it alone in developing an Advanced Medium Combat Aircraft. The DRDO's R&D chief, Prahlada, has told Business Standard the AMCA will have features more advanced than current fifth-generation fighters. That means AMCA will be technologically ahead of the FGFA when it enters service at the end of this decade.

Asked whether that might be over-ambitious, Prahlada retorts, "When we had begun the LCA programme, people asked the same question. They thought we would not be able to build a fighter with composite materials, and with an unstable aerodynamic configuration. The Tejas has proved them wrong. Today, we say we will build a fighter that is better than Gen-5. And, the sceptics will be proven wrong again."

As Business Standard reported earlier, Rs 10,397 crore have been sanctioned for developing the Tejas Mark-II for the IAF; and another Rs 3,650 crore for the naval Tejas, which would operate off aircraft carriers. Subramanyam says this total expenditure of Rs 14,047 crore would be amortised over 200 Tejas fighters, at about Rs 70 crore per aircraft. This projected order includes two squadrons (40 fighters) of LCA Mark-I that the IAF has already ordered; an expected five squadrons (100 fighters) of LCA Mark-II and another two-three squadrons (40-60 fighters) for the Navy. In addition, the manufacturing cost of the IAF Tejas is projected at Rs 180-200 crore and of the naval version at Rs 190-210 crore.

This clears lot of doubts about the Mark II, and I like the confidence coming out of the scientists, way to go.

Indian Air Force fighters to be equipped with OBOGS

The OBOG is being integrated into India's own fighter aircraft, the LCA Tejas Mark II. OBOG is based on a sieve-like structure.OBOG is fitted into the main frame of the aircraft. The function of the OBOGS is to concentrate the oxygen available in the atmosphere and removes nitrogen content from it.

"Aeronautical Development Agency (ADA) has started the ground integration process of OBOGS in the Technology Demonstrator (TD) version of the LCA Mark-II. After LCA it will be integrated in all the frontline aircraft of the IAF," says William Selvamurthy, Chief Controller, Life Science, DRDO.The OBOG is being integrated into India's own fighter aircraft, the LCA Tejas Mark II.

I am very curious to how the Mig-21 which is an all aluminum metal aircraft which is about the same size as the Tejas ends up being lighter,faster and climbs higher with its service selling at 62,000ft compared to Tejas and Gripens 50,000ft! The Migs engine has lot less thrust but manages to out perform these modern 4th generation fighters.

http://www.deccanherald.com/content/157120/tejas-sensors-checked-during-night.html

The indigenous Light Combat Aircraft- Tejas, fitted with advanced sensors like Multi Mode Radar (MMR) Litening Pod (Day and Night imaging sensors), was checked out during night flying, Defence Research and Development Organisation said today.

These sensors when integrated with the on board weapon system, makes it a potent multi-role combat aircraft, a DRDO statement said. The first phase of the night evaluation in which six night flight sorties were conducted was held yesterday, it said.

"The preliminary results indicate that the integrated system performed very well, meeting the requirements of night operations. Flight trials were conducted by the National Flight Test Centre at ADA (Aeronautical Development Agency)", the statement said.
In addition, the avionics suit includes the state of the art Helmet Mounted Display System (HMDS) and Instrument Landing System (ILS), it said. To prove Tejas's night operational capability, all these systems needed to be tested and evaluated following a detailed flight test programme during night flying in moon phase as well as dark phase, it said.

LSP-5 aircraft, which has the required cockpit lighting standard to support night flying, was used for these trials, the statement added. The night flying was started after a series of ground evaluations of the integrated system in static as well as taxi phase under different lighting conditions, it said.

With the conclusion of the first phase of night evaluations, the mood is upbeat in 'Team Tejas'. Success of the current phase of trials augurs well for achieving night attack capability for Tejas in the near future, it said.
