Any radar can be downsized to be fitted in other fighters, that's why we had the Bars 29 (smaller version of MKIs radar) on offer for Mig 29 upgrade, or why the Zhuk AE is in a bigger version is on offer for MKI now as well. It's only a matter of different diameters and reduced, or incresed number of T/R modules.

Till what extent? I think AESAs consumes more power, scale down verions too have that disadventage.

No its not true. But only EL2052 (as far as i know) can fit any fighter. As far as you bars 29 version is there, either this also falls in the same category as EL2052 or its specifically modified for Mig29 as their's not much difference between the nose of 2 fighter jets and it can't be used on LCA.

Why? What's the difference between Israeli T/R modules and US, Russian, or European? As I mentioned earlier, it's just a matter of the nose diameter and maybe the form of the nose.

Exactly, it's a modified version of the BARS radar in the MKI, which means it's mainly smaller! Same goes for the Zhuk AE AESA radar, which initially was offered in the Mig 35 and the early prototypes had a diameter of just 575mm, with less than 800 t/r modules. During MMRCA the Russians realised that they have to offer more and proposed a bigger version, with 688mm diameter and something around 1000 t/r modules. Now they offer the same radar for the MKI upgrade, which has a diameter of around 900mm and you can guess how many t/r modules that version would use.
Another obvious example is the Israeli EL 2032, which was offered for Mig 29, Mirage 2000 and is even integrated into LCA, Sea Harrier and AFAIK also in the Jaguar IMs. So in Indian forces service alone it is used on 3 different fighters with different nose diameters, which once again shows, that you can put the same radar on any fighter, the more difficult thing is, to get the clearance by the manufacturer of the fighter, to use a different radar.
No matter what, none of the MMRCAs will use an Israeli AESA radar and the way it looks like, not even Tejas will get it (because of US restrictions), that's why I hope we join some development with the MMRCA winner, or that a version of its radar for Tejas as well. The Europeans are ready to share AESA radar techs with us and would be logical choices for a stop gap AESA radar for LCA MK2, because we will produce that radar in India under licence anyway.

EW DELHI: The largely homegrown Tejas fighter is still to fight its way out of the doldrums. The jet will not become fully-operational anytime before 2013, a full three decades after the LCA (light combat aircraft) project was first sanctioned in 1983.

IAF chief Air Chief Marshal N A K Browne, responding to questions on Monday, remarked the Tejas LCA's operational clearance had been delayed by almost a year, without elaborating any further.

This indicates the actual induction of the first 40 Tejas jets will begin only towards end-2013 at the earliest, and the first two squadrons will be up and running at the Sulur airbase (Tamil Nadu) only by 2015 or so.

As per revised timelines drawn up after several cost and time-overruns, Tejas was to get the initial operational clearance (IOC) in December 2010, which basically signifies the aircraft is fully airworthy.

This was to be followed by an "intermediate clearance stage'' by December 2011. And finally, the fighter was to get the final operational clearance (FOC), when all weapon and other systems are fully-integrated into the platform, by December 2012.

Defence ministry sources on Tuesday admitted there had been slippages in the intermediate clearance stage for the lightweight, multi-role fighter after it got the IOC last January. "It will not be possible before May-June 2012 now, which in turn is likely to delay the FOC beyond December 2012. The LCA prototypes could not fly much over the last four-five months due to some technical reasons as well as monsoons,'' said a source.

DRDO, however, contends Tejas, which has "all the features of a fourth-generation fighter'', will cross the FOC barrier as planned. "Certification is a long-drawn process. It does not mean there are delays. We are very hopeful Tejas will get the FOC in December 2012,'' said a senior DRDO official.

India certainly needs to develop its own advanced weapon systems like fighters, instead of being yoked to foreign imports which make it strategically vulnerable. But the LCA project underlines the fact that a complete rethink is needed on how to run critical indigenous defence projects.

Its overall developmental cost, including the naval variant and trainer as well as the Kaveri engine, for instance, will go up to Rs 17,269 crore by 2018 from the initial Rs 560 crore earmarked for it in 1983. With each Tejas to cost around Rs 200 crore over and above this, India will eventually end up spending well over Rs 25,000 crore on the programme.

Moreover, Tejas is still only around 60% indigenous. The fighter, for instance, is powered by American GE engines, with the indigenous Kaveri engine failing to pass muster for it despite Rs 2,839 crore being spent on it since 1989.

India has inked a $822 million contract for 99 General Electric's F-414 engines, with an option to go for another 49 engines at a later stage, to power the Tejas Mark-II version. While the first 20 Tejas will be powered by GE-404 engines, the next six Mark-II squadrons (16-18 jets in each) will have the new more powerful GE F-414 engines




Hahahahahhaahahhah LCA Cant Fly in MonS0ons..... what a shame for a fighter who is not abel to fly in rain.......

CSIO develops head-up display for LCA’s naval version

Chandigarh, October 18
Close on the heels of the naval version of the Light Combat Aircraft (LCA) Tejas, undergoing ground tests of its engines, another milestone has been accomplished by the Central Scientific Instruments Organisation (CSIO) here by producing a head-up display (HUD) unit for its cockpit.

Two units of the prototype naval HUD have been developed and it is expected to be tested by the Aeronautical Development Agency (ADA) shortly before being integrated into the Tejas’ cockpit.

The CSIO had earlier developed the HUD for the air force version of the Tejas, which has been installed in prototype and limited series production versions of the aircraft. The HUD is an opto-electronic device installed above the cockpit’s instrument panel that superimposes vital flight parameters on the pilot’s vision of the outside world, giving him all requisite information at a glance and without having him to look down inside the cockpit, thus enabling him to fly with his “head up”. Air speed, altitude, weapon status, rate of turn and angle of attack are among parameters displayed on the HUD.

The HUD for the naval version has different technical specifications that the air force version and the operating parameters, cockpit configuration and the pilot’s field of vision are different. In addition, two HUD units have also been fabricated by the CSIO for the HJT-36 trainer developed by Hindustan Aeronautics Limited.

Well a few trials like the weapon release trials and CMDS trials along with maneuverability trials cannot be done during monsoons because of the poor visibility during rain. So the chase aircraft cannot record the behavior of the aircraft.

You would have known about this when Chinese aircrafts were tested in Kamra.

Tejas LSP-7 all set for its launch


Indian Air Force (IAF) pilots will officially get a taste of home-grown Light Combat Aircraft (LCA) Tejas with the 12th aircraft from the project flight-line and the seventh from the limited series production (LSP-7) block set to kiss the skies soon.
Sources told Express that the crucial engine ground run (EGR) was over and the fighter was now being put on low-speed taxi trials (LSTT). “We will do the LSTT before October 24 and the high-speed taxi trials (HSTT) after that. Finally, we will do the nose-up trial leading to the first flight,” sources said.
The aircraft is expected to do the LSTT at 150 kmph and the HSTT at 250 kmph.
Though the LSP-7 was scheduled to fly in August, the project hit an air pocket when fuel leak was noticed in one of the aircraft during taxiing. “We had to ground the entire Tejas fleet as safety was our top-most priority. We lost the months of May, June, July and August with not much of testing happening,” sources said.
Engineers had to re-arrange the butting of fuel and hydraulic pipes to avoid them coming into contact.
In the meantime, the IAF minced no words about quality concerns of Tejas user versions, putting its makers Hindustan Aeronautics Limited (HAL) in a spot of bother. “HAL took too much time in absorption of changes suggested by the user. We have definite issues with the pace of the programme. Each aircraft is now taking 24 months right from the part assembly stage. Once, Tejas is inducted into the IAF, we want HAL to put in an improvised production line,” a senior Indian Air Force official said.
To iron out all the issues, a top-level Tejas review meeting was held in New Delhi this week with all the project partners in attendance.
The IAF, which has already begun the preparations for the Tejas squadron, will have to wait for some more time before taking Tejas for the user trials. The No 45 Tejas Squadron, to be based in Sulur near Coimbatore, will be known as Flying Daggers.
FIRE POWER
Team Tejas is back in Bangalore after a two-week successful weapon trials in Pokhran and Chandan ranges of Rajasthan. For the first time, three aircraft from the Tejas flight-line have dropped a laser-guided bomb (LGB), 1,000 lb bombs and practice ammunition.
The aircraft also performed a 1,200-litre drop tank release (jettison) to test the accuracy parameters. “Close to 30 flights to check improvements and accuracy of hitting the targets were performed. The LGB trail was very critical,” sources said.
The team will now head for advanced high-altitude weapon trials in Jamnagar and Leh. Sea trials will take place at INS Hansa in Goa with Russian-made R-73 air-to-air close combat missile.
THE STORY SO FAR
