old article on MMR on LSP-3 ..The MMR is based on 2032 and developed in co operation with ELTA of israel and ADA, LRDE, HAL ,ECIL with origins on Israeli LAVI project but does not say it's range or Power out put.

http://www.acig.org/artman/publish/printer_533.shtml

The MMR radar is seen installed on the 'Hack' aircraft. This radar is being developed under the LCA 'Tejas' programme and has an intended detection range of 120 km vs a 2 sq.m target. The Hack is offered for other testing purposes as well. (CABS via B Harry)

The above is the only link that says the following things about radar range and power out put along with antenna dia,

http://www.acig.org/exclusives/LCA/ACIG_Exclusives_Tejas.html

Antenna diameter 650 mm
Antenna gain 33 dB
TWT Power Output 6.5 kW (increaseable to 10 kW, 10% duty cycle)
Range 120 km against 2 sq.m RCS aerial target, >150 km for surface targets against sea clutter
All Up Weight (AUW) 130 kg
To keep the radar up to evolving standards, a new Advanced Signal and Data Processing Unit based upon Power-PC chips, has been developed to replace the older unit.

And the reason LRDE went to ELTA for back end processor was nothing to do with the air to air mode which was done locally.

it was for the much more demanding air to ground mode to see though the ground clutter ELTA's back end processor was sought.

As far as B'harry's article on tejas is concerned they are factual reports with close sources from the program and he is covering tejas from a decade before,

What is finally on tejas mk-1 will be known only after FOC, since 80 plus range is given by DG himself , it is quite possible for it to have 120 Km tracking range for 2 sq meter target as reported. if there are any performance downfalls we will know later in FOC.

Most air to air missile launches are done well within the 80 Km range as BVR missiles targeted at their extreme ranges often lose most of the kinematic energy by the time they reach the target and dodgable.

unfortunately he died young while pursuing his higher studies in US.

There is a separate thread in BR dedicated to his memory.

@Archer
Archer's post here, i think he is also a member here,

-A2A modes validated, look up/look down, including 10 target TWS
-Software work/trials on STT going, then dual STT
-A2G SV-2000 radar for ALH has SAR/ISAR
-A2G Modes on MMR will be done next
-LRU count on MMR reduced, all hardware realized
-SP/RC combined into one unit - with 3 Sharc processors, substantial weight/ volume savings..
-MMR has a range of upto 150Km, with substantial growth potential with a new TWT
-The Hack test aircraft has detected a Kiran at 60/45 km...but that is because of the wide space difference between the antenna and LRUs..with losses, in the Hack. This was apparently what the media reports referred to..the dumb journo mixed it up with the LCA..the LCA will have the LRUs next to each other..

Interim fit whilst the MMR gets ready, Elta 2032 radar

http://www.worldaffairsboard.com/military-aviation/17427-excellent-lca-info-14.html

The MMR was revealed to much further along than previously thought (A2A modes), with software work on A2G modes being assisted by Elta. Hardware has been realised, with software modules for A2G modes to to be added. Only a few 2032's have been brought as well. The 20 LCAs on order had their Ge-404 IN-20s cleared. The earlier stuff about the RF losses from widely spaced LRUs turns out to be journalistic BS about the MMR on the Hack, and reported as being on the LCA (the MMR is actually slated to go on the LSP 3)

Karan M.'s post

Its helps to look into the details before getting all upset and posting off the cuff.

Indian standard RCS for calibration is 2 sq mtrs. The MiG-29 radar range is detailed for a standard RCS of 5 Sq Mtr.
With the quartz radome (which means less loss in radome itself) the 80+ km for 2 sq mtrs translates to 100+ km for the LCA against a target of 5 Sq Mtrs, which is a fairly decent range for such a small fighter with a low RCS itself and in line with what the radar is designed for.

Two important points to gleam from this document:

1. The clean take off weight of Tejas is 9800 kg. This is in conflict with all previous known specs including those given on the official Tejas website. It will be interesting to see what has been causing 300 kg increase in take off weight.

2. ADA is looking at an alternative engine for mk2. Kaveri K10 after all maybe?

 

[rvjpheonix]

Can someone tell what all is included in the take off weight in comparison to empty weight apart from fuel?

 

[p2prada]

@p2prada

ADA wants an alternate engine for mk2. Probably for export? Can K10 be completed in time

I don't know about that. MoD decides and as of January 2013, MoD has already made a decision that K-10 won't be part of LCA.

Apart from that, K-10 is still years away from being a real engine, let alone something that can be equipped on a fighter. It will be a big deal if AMCA's LSPs get the new engine, so you can imagine how much time it will take.

Interesting day ahead for Tejas.

We are offering a battle-ready Teajs to IAF now: ADA Chief Tarmak007@ Ananth Krishnan

The Aeronautical Development Agency (ADA) chief P S Subramaniam says that Tejas is completely battle-ready and its increased number of flights in the last 3 years (over 1000) is a testimony to the maintenance, safety and operation features of the aircraft. In an interview to Express on Thursday, Subramaniam said that the Tejas has proved its flying capabilities at all important Indian Air Force (IAF) and a couple of naval bases.
"This year we have touched almost 500 flights and have conducted outstation trails at Jamnagar, Jaisalmer, Gwalior, Leh, Utterlai (near Jodhpur) and Goa. The aircraft has demonstrated the capabilities to operate like a typical squadron. On many occasions the same aircraft has flown more than once in a day. Many have accused us in the past that Tejas was not capable of flying more than once in day. But we have demonstrated flying thrice in a day, which is a pointer towards the ease at which it can be serviced," the ADA chief said.
He said many local IAF technicians have appreciated the flying and serviceable qualities of Tejas, which was against the general opinion. "Today, the product speaks for itself and we were all glued to improvising its performance for the last many years. The weapon delivery capabilities of Tejas in many modes were demonstrated and over a dozen times we have fired the R-73 E missile. The electronic warfare trials were also conducted at an IAF base in central India," Subramaniam said.
He said the Tejas is fully battle ready and over the years his team has converted it into a fighting machine from a flying machine. "The IAF is convinced today that they are accepting an aircraft which is completely combat ready. The IAF team in ADA interacted constantly with us to make sure that they get a maintenance-friendly aircraft. The IAF wanted us to cut down the servicing time, which has been done on priority. Today, if Tejas goes for a combat mission, it can be readied for another mission within an hour's time," Subramanian said.
The ground support equipment specifications have also been evolved. There are about 20 major ground equipment developed for Tejas. "We have also made some new tools for the IAF technicians and many of their concepts have been incorporated. Today Tejas is a fighter evolved from hundreds of feedback we received from designers, engineers, pilots and technicians. We have gone through the motions of making a new generation fighter and faced many difficulties. The induction of Tejas into IAF will being soon and that should silence most of the critics. Plane-making a serious business and making military platforms is a complex exercise. We have covered some distance and Tejas is the answer," he said.

Group Captain Suneeth Krishna interview with TOI

"Kick the tyre and burn the fire . It's ready ," one of them said a day before IOC-2 is scheduled here . Group Captain Suneeth Krishna , who has been involved with the aircraft since its first flight on January 2001, said : "It is a pilot's aircraft ."

Krishna had flown a Mirage trailing the LCA when it took off for the first time over 12 years ago with Wing Commander (retd ) Rajiv Kothiyal at the controls .

Today , the aircraft is different .Comparedtotwo years ago , the angle of attack has been increased to 24 degrees from 17, it has been integrated with a basic electronic warfare suite, has lesser maintenance issues, more weapons and comes with an enhanced flight envelop .

"I remember the first flight vividly . Wing Co Kothiyal and I took off together . Andtoseethatwhitecraftlift off was a moment of unrivalled pride . It was ours and it was flying . Today , I'm proud because it has evolved ," he said . Like most IAF pilots of his time , his heartiswiththeMiG . "AMiG is a MiG, our first aircraft . We used to call it the Ferrari ," he says . MiG-21 FL was decommissioned last week.

So what's the LCA? "It's better than the Ferrari ," he says . "It has an inherent advantage . We have the design , so we can alter it to our needs . Also, inputs from flying the MiG, Mirage and Sukhoi have been used in designing the cockpit . I can say it's the best. The pilot interface is amazing ," he said .

Tarmak007 -- A bold blog on Indian defence

DRDO's most prominent voice Dr K Tamil Mani, Director-General (Aeronautical Systems), says that his organisation is working parallel to get few Indian weapons integrated on Tejas. "Though to integrate Indian weapons is not a planned test point for the final operational clearance (FOC) of Tejas, we have started working on it for some time now. The Astra missile integration with an improvised range of 80-plus km (currently 40-45 km) is the next big challenge.

An onboard oxygen generating system (OBOGS) is also in the pipeline for Tejas. The OBOGS development work is being undertaken by the Bangalore-based DRDO life sciences lab Defence Bioengineering and Electromedical Laboratory. "The OBOGS enables the pilots to fly at high altitudes and on long duration sorties without the help of oxygen cylinders. We are also planning to get an Indian company to supply the tyres for Tejas, which currently runs on Dunlop," Tamil Mani said.
The engine (GE F 404), ejection seat (Martin Baker), missile (R 73 E) and the multi-mode radar (Elta) are among the prominent import content onboard Tejas now.

Indigenous Fighter Aircraft LCA -Tejas Poised for IOC-II

The country's indigenously designed and developed multi-role supersonic fighter aircraft LCA-Tejas will get the Initial Operational Clearance (IOC II) on Friday, a significant step towards its induction into IAF squadron.

Light Combat Aircraft Tejas, a single engine, light weight and highly agile frontline fighter, will receive IOC II at a function to be attended by Defence Minister A K Antony in Bangalore on Thursday.

On the eve of the milestone, Defence major Hindustan Aeronautics Limited said the production facilities have been set up at HAL and the aircraft delivery is expected to commence from 2014.

"We have plans to initially produce eight aircraft per year. Further plans are afoot to enhance the production rate to 16 aircraft per year in consultation with IAF and MOD (Ministry of Defence)", HAL Chairman Dr R K Tyagi said.

He said, "HAL is fully geared up to meet the challenging production schedule and hopes to fulfil the requirements of customers in a time bound manner."

The aircraft will, however, have to cross several milestones before it receives the Final Operational Clearance (FOC), expected in 2015.

HAL carried out around 500 sorties of LCA in 2013, the highest for any particular year right from the start of the programme, which has been bogged down by delays.

Outstation flight trials were carried out at Leh, Jamnagar, Jaisalmer, Uttaralai Gwalior, Pathankot and Goa for cold weather, armament and weapon deliveries, MultiMode Radar (MMR), Radar Warning Receiver (RWR), hot weather and missile firing flight trials this year itself,Tyagi said in a release.

After IOC II, HAL will go ahead with the Series Production of LCA Tejas, he said.

LCA has also successfully demonstrated weapon delivery capability during weapon trials at Jamnagar and Jaisalmer.

HAL has been working towards building up infrastructure for production, he said, adding, with most of the aircraft system performance reaching desired levels, HAL production group would concentrate on stabilising the production line.

The production line at HAL has been moved to new premises with a built up area of around 28,000 Sq m of Hangars, Engineering and Administrative blocks.

Upgrade and augmentation of production tooling is underway to enhance the rate of production and to expedite delivery of aircraft for two IAF squadrons in the next four to five years,Tyagi said.

Two senior pilots Group Captain Suneet Krishna and Group Captain Ritu Raj Tyagi will demonstrate the maneuverability of these battle-ready fighters to defence minister A.K. Antony and minister of state for defence Jitender Singh before Chief of the Air Staff Air Chief Marshal NAK Browne receives the service documents of 'Tejas'.

The induction of this fighter marks the fruition of a project which was launched 30 years ago. "We must be proud of our designers and pilots who have overcome many hurdles and the technological embargo announced by the United States, post Pokhran-II tests in 1998. We have proved that we can design and fly a fighter. It has flown almost 2,500 sorties without a glitch, which is definitely a major achievement. We must explore the option of exporting it to South Asia and other parts of the world," Dr V.S. Arunachalam, former scientific advisor to the defence minister, who initiated the project in 1983, told Deccan Chronicle.

Sources in Indian Air Force said though it was originally designed as a replacement for MiG 21, it was far superior to the Russian fighters and could be classified as a fourth generation fighter jet.

Meanwhile, Hindustan Aeronautics Lim-ited (HAL) said production facilities have been set up to roll out the fighters beginning 2014. "We have plans to initially produce eight aircraft per year. Further plans are afoot to enhance the production rate to 16 aircraft per year in consultation with IAF and MOD (Ministry of Defence)", said HAL Chairman Dr R.K. Tyagi.

There are many definitions of take off clean,

1.One is without seven pylons and without two short range missiles,

2.the other is with seven pylons and two short ranged WVR missiles fitted on,

We don't know whether TOW clean pertains to first or second nomenclature here,

Most of the time ADA uses the second nomenclature as take off weight clean

If it is the case then 3.5 ton stores+ the weight of seven pylons and two R-73s(2x75 Kg=150 Kg) comes somewhere close to 3.75 tons ,

We need to wait a bit before which nomenclature was used for take off clean.

Today , the aircraft is different .Comparedtotwo years ago , the angle of attack has been increased to 24 degrees from 17, it has been integrated with a basic electronic warfare suite, has lesser maintenance issues, more weapons and comes with an enhanced flight envelop .

So it has already reached 24 deg AOA according to the most experienced test pilot on the flight test program, So certification for IOC-2 purpose has been restricted to 22 deg is the meaning of DG's statement, I suppose.

SO we can improve even beyond this 24 deg if we take the previous statement as a guide-"We've achieved certain targets and have some before the final operational clearance (FOC). Even after that , we can keep improving it,"

possible since the aerodynamic layout has Cl max peaking at 35 deg AOA,

and

with the augmented support rudder control is decent even in 30 deg AOA

Tejas all set to get certification for IAF induction - The Hindu

Made of composite materials, which weigh less than a fifth of metal, the aircraft has marked India's entry into a select group of nations that can build such flying machines from scratch.

Almost 30 years after it was conceptualized and 20 years after funds were released for it, India's indigenously designed and developed frontline fighter aircraft, Light Combat Aircraft (LCA) Tejas, is all set to get the Initial Operational Clearance (IOC II) here on Friday that would pave the way for its induction into the Indian Air Force squadrons.

Though, the 14 aircraft that have been produced by Hindustan Aeronautics limited so far have clocked nearly 2,500 hours of flying, some of the 11 having flying capability would again take to the skies on Saturday in the presence of Defence Minister A.K. Antony during a function at the LCA-LSP Hangar of HAL , where the IOC II would be handed over by the Centre for Military Airworthiness and Certification (CEMILAC) to the Indian Air Force.

Director General Aeronautics and Chief Executive of CEMILAC Dr. K. Tamil Mani told The Hindu that Tejas was the best aircraft in the LCA category. Apart from being the lightest, with a gross weight of just about 9 tons, it was also the most cost effective as its price ranged from between Rs 170 and Rs 180 crore, which was almost a third of similar fourth generation aircraft.

He said the aircraft is capable of carrying nearly three tons of weapon systems, including laser guided and 500 kg bombs, has a top speed of 1,350 km per hour, capability of withstanding 7 G gravitational force and a 400-500 km radius of operation. However, before it is inducted, the Air Force wants the aircraft to improve its angle of attack from 24 degrees to 28 degrees, possess capability for refueling in air and to possess modern missile systems.

Made of composite materials, which weigh less than a fifth of metal, the aircraft has marked India's entry into a select group of nations that can build such flying machines from scratch.

Dr. Mani said the LCA project has been developed at a cost of nearly Rs 10,000 crore. The aircraft are likely to go into series production and be inducted into the Air Force in the first half of 2014.

To meet the growing demand, the HAL would be ramping up the production from 4 aircraft in 2014 to eight each in the following two years and 16 in the years thereafter. By 2016, the IAF is expected to raise its first squadron of Tejas LCA aircraft.

While Tejas seeks to mark India's entry into the 10 ton aircraft category, it is also a technology demonstrator for the nation and has even showed the country's resilience in standing up to the challenges of denial of technology, as was experienced when the United States had banned the supply of critical flight control equipment in the wake of the Pokharan nuclear tests, said Technology Director of Aeronautical Development Agency, V. Subbu Rao.

Mr. Rao, who has been associated with the project for 26 years, said "entire design and concept is ours and the Mach 1 LCA is better than its contemporaries such as Mirage 2000, F-16 and Gripen." Moreover, he said, with not a single accident the aircraft has shown a high degree of durability.

Though Tejas have been equipped with GE engines, efforts are on to use Indian Kaveri engines on it. However, the lower thrust provided by the Indian engine remains an area of concern. The Indian engineers are also trying to develop their own radar system for the aircraft, which to begin with would be fitted with Israeli systems.(might be the ASEA effort? or ?)

Mr. Rao said while the development of Tejas has taken a long time, it has led to the creation of huge log data on problems faced. "We are now in a better position to develop the fifth generation fighter aircraft, which come with stealth technology and super cruise, as also the Advanced Medium Combat Aircraft, which is at an advanced design stage.

Timeline clearly mentioned as 30 years after conceptualized and 20 years after the funds were released,

So getting a fully functional 4.5th gen fighter battle ready with ,

all glass cockpit,

RSS fly by wire compound or cranked delta,

below 0.3 sq meter clean config RCS

100 Km plus tracking range for fighter sized target MMR which has a decent 32 db gain and 650 mm antenna dia, enabling the mating of longest range BVR missiles at present,

highest percentage of composites among 4.5th gen fighters leading to long air frame ,

with lowest wing loading

a TWR of to 1.07 , higher than Mirage-2000's (half fuel load with just two WVR missiles added for weight)

capable of landing and taking off from high Himalayan airfields of LEH, with weapons from day one,

internal EW suit,

with a fully finished ground attack component,(not done on TYPHOON till date)

along with HMD enabled high off bore lethal WVR missiles for close combat (still not present in RAFALEs of France)

along with an in flight refueling probe with pressure refueling in 3 minutes , doing away with range limitations,


in 20 years time from the fund release is almost at par with global standards of any modern 4.5th gen fighter program

that too at a third of cost with minimum forex outgo in the face of Nuclear test related sanctions,

Also a fifth of the 2500 flight tests have built up a database of flight control laws that will be used by all new fighters to be designed like AMCA is an added bonus,


tejas radius of action is 400 to 500 Km as per the report

As per this report gross weight is 9 tons ,

So is it 6 tons empty air frame weight and 3 ton fuel weight

or

6.5 ton empty air frame weight and 2.5 ton fuel weight?

or

6 tons empty weight, 2.5 ton fuel weight and 0.5 tons of (hydraulic fluids + ammo + 7 wing pylons +pilot )

Lets wait for some more reports for final clarity on these aspects,

However it has good fuel fraction

IAF wants Tejas AOA to be raised to 28 deg same as that of any other 4.5th gen fighter, and since the air frame is capable will it be achieved in mk-1 or will it be a target for Mk-2?

And AMCA is at an advanced stage of design .
