Manc!!!! The nose cone in the second pic is goofed up a bit.... The Radome is looking up a bit and is too sharp at the cone.....The radome makes some 6 deg with vertical axis!!!
ppgj!!! you have given me lot of home work by giving the link on DARIN!!!! thanks ...let me read and try to understand ..because there is DARIN II etc..Initial F404 F2J3 had no FADEC ,where as F404 IN20 has FADEC with 1553B bus control i believe!!! otherwise there is no change in thrust and weight specs.

here are things as of 21 june 2010.
TEJAS MARK2 engine negotiations set to start in 2 weeks( whew finally!!! i thought these engines may become obsolete the way ADA was going about it). as of now ADA says both eurojet and GE engines are acceptable. so final decision will be mostly on issues concerning who offers high end technology transfer. no word on what modifications fuselage of tejas will have to undergo.
The current lot of mark 1 tejas engines(F-404) WILL BE REPLACED BY KAVERI SNECMA HYBRID AS AND WHEN THAT BECOMES AVAILABLE. THE TIME FRAME QUOTED NOW IS 4-5 YEARS.HAVING SAID THAT sNECMA jv IS STILL UNDER CONSIDERATION DESPITE CLEARANCE FROM mod. THIS I REALLY FAIL TO UNDERSTAND.
NO WORD ON KAVERI MARK1. ALL SILENT ON THAT FRONT. DID IT "FLY" IN RUSSIA OR THROW UP(BLADES)?

Tejas cockpit will be a pilot's delight
June 21, 2010 9:54 IST
Bangalore: Test pilots flying India's much-debated home-grown fighter Tejas (Light Combat Aircraft-LCA) will soon experience a cool and compact cockpit.
The fifth limited series production (LSP-5) platform of Tejas, set to fly in the first week of August, will have an onboard "re-arranged and modified cockpit" to increase the comfort levels of the pilot.
Program director (combat aircraft) and director of Bangalore-based Aeronautical Development Agency (ADA) PS Subramanyam told DNA that the layout changes will make the glass cockpit more pilot-friendly and even enhance its night flying capabilities.
"The new cockpit will be a pilot's delight," said Subramanyam. "The pilots are happy as they are also doubling up as designers. Our efforts are to bring down the workload of pilots during the mission. All the 12 pilots who were part of the Tejas programme from the beginning have contributed their bit to the cockpit modifications. The pilot is the man in action and our role is to ensure that we give him everything he needs while flying," he explained.
Air Marshal PK Barbora, vice-chief of Indian Air Force (IAF), told DNA that a user-friendly and smart cockpit would make the hand-eye coordination perfect.
"Your hands must be able to move around relatively easily, the way you normally do. Even if there's an emergency, the right signal must come to you instantly enabling you to take swift action. Hence, a cockpit plays a decisive role," Barbora said.
Sources in the Indian Air Force(IAF) said that the information flow to the pilot has increased 10-fold as compared to before. "Earlier the pilot had to manually involve in many actions, but today he is fed information intelligently in a format which can input it. This will enable him to choose the correct weapon and use them very optimally. Today the data flow to the pilot and back is monitored by the ground base, sensors, other aircraft and Air Borne Warning and Control Systems (AWACS). Hence, the cockpit has to be suited to various networking options," an IAF official with Air HQ said.

Final Configuration Tejas LSP-5 To Fly In August
BY: AVIATION WEEK
P.S. Subramanyam, program director for combat aircraft and director of the Bengaluru-based Aeronautical Development Agency (ADA), tells AVIATION WEEK that designers, engineers and scientists from ADA and Hindustan Aeronautics Ltd. are working together to make the LSP-5 a complete, final configuration platform.
"We are aiming for an August first week flight, and slight modifications to the cockpit are being done now in mutual consultations with the test pilots from National Flight Test Center. These modifications will make Tejas a complete services version," Subramanyam says.
Air Marshal P.K. Barbora, vice chief of the Indian Air Force (IAF), says it is important for any fighter jet program to develop cockpits that fulfill pilots' growing needs.
"It's all about how fast you can execute a mission," Barbora says. "Here the hand-eye coordination becomes crucial and you should also be able to move around your hands the way you normally do."
LSP-5 will be the 11th platform to join the flight line, and ADA is planning to make LSP-6 a completely experimental aircraft.
"We are confident of LSP-7 in September 2010 and the final LSP-8 in December 2010, paving way for the initial operational clearance," Subramanyam says.
The Tejas program received a major boost following ADA's establishment of a project monitoring team consisting of IAF experts, headed by Air Vice Marshal Shankar Mani. "These people are the pacemakers, and there's a definite boost to program after their involvement two-and-a-half years back," Subramanyam says.
The Ministry of Defense, which recently announced a series of reforms in the Defense Research and Development Organization, is also planning a Mk-II version of Tejas, which features an engine with more thrust. ADA is hoping to fly the Tejas Mk-II by December 2014.

India To Roll Out Tejas Naval Variant Soon
The Tejas Light Combat Aircraft's (LCA) naval prototype (NP-1) will be rolled out for the first time on July 6 here in Bengaluru, with Chief of Naval Staff Adm. Nirmal Verma on hand, sources tell AVIATION WEEK.
The Aeronautical Development Agency (ADA), which is in charge of the design and development of Tejas variants, and Hindustan Aeronautics Ltd. (HAL), ADA's principal partner and main manufacturer, are currently giving the aircraft a final structural fine-tuning at HAL's Aircraft Research and Development Center.
"The rollout of the aircraft signals that the platform is structurally complete, equipment installed, and plumbing and wiring completed," a source says. "It will be on its wheels and can be moved by assisted power. A rollout is also a precursor to the next phase of ground-based system integration testing, engine ground run, taxi trials and the first flight."
The NP-1 will have almost the same system architecture as the Tejas Indian air force trainer version.
The NP-1 trainer is scheduled to make its first flight by the end of this year and the NP-2 fighter one year after that. Both can operate from an aircraft carrier with the ski-jump takeoff and arrested recovery concept.
"The aircraft will get airborne in about 200 meters over the ski jump on the ship, [versus] a land-based takeoff run of about 800 meters," a source says. "Landing on the ship is with an arrester hook on the aircraft engaging an arrester wire on the ship. The aircraft then stops in 90 meters, which is about 1/10th of land-based stopping distance. This makes the Tejas naval program extremely challenging, and we are happy with what the Naval Project Team based out of Bangalore has done so far."
The 14-member NPT is headed by Cmd. C.D. Balaji (ret.), program director for LCA Navy, operating out of ADA.
The Cabinet Committee on Security (CCS) sanctioned development of LCA Navy in April 2003, and in December 2009 the CCS also approved a Mark-II version with a new engine. NP-1 will fly with a GE-404 power-plant, with 40% of the funding coming from the Indian navy and 60% from the Defense Research and Development Organization. The Tejas naval variant will replace the aging fleet of Sea Harriers, and the navy is said to have made an initial commitment to 50 Tejas after the platform proves its mettle.

Indian Navy fastens its seatbelt for Light Combat Aircraft Tejas
Bangalore: India is preparing to unveil its first naval variant of Light Combat Aircraft (LCA) Tejas on July 6 —15 years after the Indian Air Force (IAF) version of LCA's technology demonstrator (TD-1) was first rolled out in 1995.
The naval prototype-1 (NP-1) is currently undergoing a series of checks inside the high-security hangar of Bangalore-based Aircraft Research and Development Centre (ARDC).It will be rolled out in the presence of Chief of Naval Staff (CNS) Admiral Nirmal Verma, sources told DNA on Tuesday.
"The two-seater naval variant for aircraft carrier operations, NP-1 will be rolled out on July 6 in Bangalore," sources said.
Both Aeronautical Development Agency (ADA), the nodal agency for the design and development of Tejas variants, and HAL, its principal partner and main manufacturer, were tight-lipped about the roll-out.
An aircraft's roll-out means that it is structurally complete with equipment installed, and plumbing and wiring completed.
It will be on its wheels and can be moved by assisted power. A roll-out is also a precursor to the next phase of ground-based system integration testing, engine ground run, taxi trials and the first flight. Kept under wraps, the Tejas NP-1 will have almost the same system architecture as the Tejas IAF trainer version.
"Externally it might look the same like the Tejas trainer, but internally it is a different kettle of fish. We are confident that ADA-HAL will make NP-1 (trainer) ready for the first flight by the end of this year, and NP-2 (fighter) next year," sources said.
The Cabinet Committee on Security (CCS) sanctioned development of LCA for the Navy in April 2003, and in December 2009, the CCS gave its go-ahead for a Mark-II version with a new engine.
NP-1 will fly with a GE-404 engine. NP-1's 40% of the funding is from the Indian Navy while 60% is from Defence Research and Development Organisation (DRDO).
The naval variant of Tejas will replace the aging Sea Harrier fleet and the Indian Navy is said to have shown an initial commitment for 50 Tejas aircraft after the platform proves its mettle.
Both NP-I & NP-2 are tailor-made to operate from an aircraft carrier with the concept of ski-jump take-off and arrested recovery (STOBAR).
"The aircraft will get airborne within 20 metres over the ski-jump on the ship as against a land-based take-off run of about 800 metres. Landing on the ship is with an arrester hook on the aircraft engaging a ship-based wire.
The aircraft then stops within 90 metres of touchdown — about
one-tenth the land-based stopping distance.
This makes the Tejas naval programme extremely challenging and we are happy with what the Naval Project Team (NPT) based out of Bangalore has done so far," sources added.
A 14-member Naval Project Team headed by Commodore (Retd) CD Balaji, programme director, LCA Navy, is monitoring the project's progress from ADA in close association with ARDC.
Balaji was not available for any comment.

There is some problem with quoted land based take-off run distance. A full afterburner/full thrust and ski-jump can't make difference of 600m. On other side 800 meters sounds long even for bombers let alone any fighter. I guess it's a typo and real length should be around 400m..

India Establishing SBTF For Naval Tejas
Jun 23, 2010
By Anantha Krishnan M.
BENGALURU, India
India is setting up its first shore-based test facility (SBTF) to flight test the naval version of its homegrown Tejas Light Combat Aircraft (LCA).
The SBTF will be established at the naval air station in Goa and will be the third such facility in the world along with those of the U.S. and Ukranian navies. The Aeronautical Development Agency (ADA) and Hindustan Aeronautics Limited's (HAL) Aircraft Research and Development Center are concluding last-minute, end-to-end tests in Bengaluru leading up to the aircraft's July 6 rollout (Aerospace DAILY, June 23).
"It's a near-perfect recreation of a ship on the shore," a naval source tells AVIATION WEEK. "The SBTF at Goa is based on India's Indigenous Aircraft Carrier [IAC] that's being built at Cochin Shipyard, with the same measurements. The facility simulates an aircraft carrier with ski jump and arrested recovery."
SBTF's steel structure is being constructed by Goa Shipyard, while all civil engineering activities are being conducted by Research & Development Establishment (Engineers), Pune.
"The integration and installation work of all the specialized equipment for the facility will be done by the Russians," an official says. "This facility is a major boost to the Tejas naval program, as the Indian government had included all the necessary funding for the SBTF program [which] was cleared in 2003. We have been very keenly following this program right from the word go."
The naval test pilots attached to the National Flight Test Center will carry out all the initial flights of the NP-1 and NP-2 naval Tejas prototypes at HAL's military airport in Bangalore leading up to the carrier-suitability test (CST). The unit will then move from CST to SBTF. The takeoff area ramp will be ready by the last quarter of 2011 and the landing area will be complete in 2012. A full-fledged telemetry unit also is coming to Goa.
Sources also confirmed that in addition to training Tejas naval pilots, the SBTF will have the ability to train MiG-29K pilots prior to carrier operations.
The SBTF is being established under the guidance of the Naval Project team operating from ADA in Bangalore.

India's LCA AESA Radar Programme Detailed
The images above, seen here for the first time, are from official material on the Indian AESA radar project for the LCA Tejas, shared with LiveFist. Indian state-owned radar developer Electronics R&D Establishment (LRDE) is in the process of identifying a development partner (DP) for an indigenous AESA radar for future tranches of the Tejas and the Advanced Medium Combat Aircraft (AMCA) and is likely to make a final decision shortly. The radar has begun development in the country. According to official updated material made available to LiveFist, the fully solid-state X-band radar is being developed with the following modes:
Air-to-Air: Multi-target detection and tracking / Multi target ACM (Air-to-Air combat mode) / High resolution raid assessment
Air-to-Ground: High Resolution mapping (SAR mode) / AGR – Air to Ground Ranging / RBM – Real Beam Mapping / DBS – Doppler Beam Sharpening / Ground Moving Target Indication (GMTI) / Ground Moving Target Tracking (GMTT) / Terrain Avoidance (TA)
Air-to-Sea: Sea search and multi target tracking / Range Signature (RS) / Inverse Synthetic Aperture Radar (ISAR)
As I've reported here before, the development partner that LRDE identifies will be responsible for "detailed design, development and realisation" of (a) antenna panel constisting of main antenna, guard antenna and sidelobe cancellation antenna, (b) transmit/receive modules/groups, (c) RF distribution network consisting of RF manifold/combiners, RF interface, (d) antenna/beam control chain consisting of T/R control and T/R group control, and (e) array calibration/BITE among other areas.

These reports of an X-band radar developed have they been confirmed?? This would make LCA a much more deadly fighter than anyone anticipated.

N, LF, what instead is conformed is that they are planing a X-band AESA for LCA MK-2 and LRDE is looking someone which can develop T/R modules for it as well as help in its integration with signal processor. In my opinion its a good decision and in time will allow LRDE to develop its own T/Rs.

Rahul. Hyderabad based Astra microwave and GATEC are more than capable of doing T/R modules provided they have access to GaAs/GaN based MMIC required for the realization of T/R modules from US based companies. The other thing is cooling of around 700T/R modules and the associated power supply modules in the given 700mm Antenna dia. They have to go in for liquid cooling system based on PAO coolants with plumbing and cooling system in the given limitesd volume. The other thing is digital adaptive beam forming and scanning of the radar beam,which requires a high speed processor based computer system, which is generally called as beam forming computer. But the crux of the problem is availabilty of proven algorithms for the various A_A,A_S and A to sea for a radar operating on a moving platform. How ever fast the proessing power can be ,with out strong algorithms ,whether its a PESA,AESA or MESA , the fate will be all the same.
