UTTAM Aesa Radar prepped for integration on LCATejas

UTTAM a multimode, solid state active phased array radar indigenously developed by LRDE has completed extensive ground trials from highrise rooftop testing to demo mount on Helicopter and now is been prepped for integration on LCATejas to commence flight trials. idrw.org was informed that LCATejas LSP2 has been selected to be used has a flying testbed aircraft for UTTAM Radar integration and once integrations are complete LRDE will take around two years for flight trials to completely test radar on all modes. Software coding for all multiple modes have been completed and soon LRDE will begin the process of integrating the software to allow radar to work on multiple modes. at present Three semiassembled UTTAM Aesa Radar were designed, built, and assembled for developmental and ground trials and soon LRDE plans to develop Three more fully/semiassembled radars soon to fast track its development. LRDE, before it starts integration process on LCATejas, will start integrating the radar with the rest of the mission systems suite.UTTAM Aesa Radar has target detection capability up to 150km and can track 6 targets with high accuracy suitable for firing missiles. UTTAM Aesa Radar once in production will be used on LCATejas MK2 aircraft while LCATejas MK1A most likely will be getting Israelideveloped ELTA’s EL/M2052 AESA Radar which already has been procured for Jaguar Darin III upgrade Strike jets.

LCA Tejas is far superior than Mirage-2000 and the Chinese JF-17


After building light combat aircraft (LCA) - Tejas - India's target is to build fifth generation fighter aircraft (FGFA) indigenously. This is what H Siddesha, project director and technology director of LCA at the Aeronautical Development Agency of Ministry of Defense said here on Friday.

Siddesha was in the city to deliver a guest lecture on the inaugural day of Footprints X7 - Gujarat's largest technical event organised for three days by the students of M S University's Faculty of Technology and Engineering for the seventeenth consecutive year.

FGFA, which is under development, is very much a future requirement for the Indian Air Force (IAF) upgrade programme. "It should take flight in 2028," he said.

Talking about Tejas, which has been inducted in the IAF, he said, IAF has placed an order of 123 Tejas Mark 1. "Every year, 16 Tejas aircrafts will be built on two assembly lines. By 2024, all the aircrafts will be inducted in the IAF whereas Tejas Mark 2 version will be ready by 2021," he said, adding that Tejas is superior than France's Mirage and China's JF-17 fighter jets.
"So far, Tejas has taken 4,000 flights and in none of them it has met with even a minor accident which is a record in itself.

The technical staff can replace engine of Tejas within 45 minutes and the cockpit and flight control system are world class," he said, adding that although some countries have evinced interest in procuring Tejas from India, the government is yet to take the decision on whether it should be exported. On the inaugural day of Footprints, Dr Ulrich Bez, former CEO and current non executive chairman of Aston Martin also delivered a guest lecture while a workshop of 'Biped Robotics' where participants were taught how to make an autonomous robot capable of running, walking and even doing 180 degree split was taught to the participants.

[tejas warrior]

The original cockpit config of MK2 ..

So, this is work in progress and gradually they r improving it. Initial design may be couple of years old.

I like the new one large screen display.

IMHO, they should consider same for MKIs upgrade.

 

[Kunal Biswas]

The featured Elbit NG cockpit is offered for MK2 which is not officially considered, Its also under Mr Gupta`s wish list as he keep posting its picture every year in his blog ..

But the very real upgrade is already featured on MKI, which is researched by DARE ( GOI ) under ToT by foreign counterpart and transferred the know how to local partners for manufacturing..

This is a very promising upgrade that can be done for MK2, The same MFDs are being used on Russian 5th generation prototypes and their own 4.5 generation front-line fighters.

So, this is work in progress and gradually they r improving it. Initial design may be couple of years old.

I like the new one large screen display.

IMHO, they should consider same for MKIs upgrade.

Fun things is, our tejas cockpit display is of 3k resolution which even beats some current displays in TV market, I am saying this because I own a MS surface pro 4 is of 2k display. So higher the resolution means more screen real estate and more visuals can be packed in. But where's the weapon queuing UI, is it on some other smaller display unit? But gotta say the the MFD's on those SU27 looks badass!

 

[HariPrasad-1]

Tejas MK-2 (Air force version) will be 0.5 metre longer, will be able to carry a payload of up to 5 tons with MTOW of 16.5 tons.
https://twitter.com/SJha1618?ref_src=twsrc^google|twcamp^serp|twgr^author

If MTOW is 16.5 T on means engine dry thrust 66 KN Atleast and If i consider empty weight 6.150 tons and fuel weight 3.5 tons and other 500 kg even than it will be able to carry 6 tons easily. This is an MMRCA capability.

How about conformal tanks on mk2???

Testing on LSP's would be good in future

SAAB OFFERS WORLD CLASS SENSOR PACKAGE FOR INDIAN TEJAS LCA

Defence and security company Saab offers a fighter sensor package for the Indian Tejas LCA Mk1A fighter aircraft. The package consist of a state-of-the-art Saab AESA fighter radar closely integrated with a compact electronic warfare suite using Gallium Nitride based AESA technology.

Saab, in partnership with Indian industry, offers a solution that will bring the required Airborne Electronically Scanned Array (AESA) Fighter radar and Electronic warfare capability to India and the Indian Air Force. Thanks to our extensive technology development Saab can offer the latest technology, on time for the LCA Mk 1A needs, at low risk.

The AESA fighter radar is developed by Saab with antenna technology based on the latest technologies using Gallium Nitride (GaN) and Silicone Carbide (SiC) substrates in combination with the latest generation of exciter/receiver and processor technology, giving optimum installed performance in a dense signal environment.

The radar has a complete mode suite which includes air-to-air, air-to-ground and air-to-sea capabilities. A built-in memory provides a tool to record a large amount of data from performed flights. Integration in the LCA Mk1A fighter aircraft is enabled by the limited space, power and cooling required.

The EW suite consists of sensors and transmitters developed by Saab and is a highly capable and extremely compact solution that provides essential situational awareness and self-protection. The heart of the suite is an alectronic warfare receiver which is connected to a front end receiver and fin tip antennas inside the aircraft. Included is also an external AESA jammer pod.

The radar warning system is based on ultra-wideband digital receivers and has very high probability of intercept, very good sensitivity and very high selectivity for handling the complex signal environment of today.

The AESA jammer pod is small in size, low on weight and drag. Self-protection is based on Wideband Digital RF Memory (DRFM) that provides advanced jamming techniques and arbitrary combination of jamming waveforms. Transmission is performed by using GaN-based AESA:s. The EW suite also includes ground support systems and recording capability for advanced mission planning and post flight analysis.

Saab’s solutions are based on the latest state-of-the-art technologies and COTS (commercial-off-the-shelf) available. The AESA fighter radar and electronic warfare units have no ITAR-restricted (Internationally Traffic in Arms Regulations) components, due to the high degree of Saab in-house developed and manufactured building blocks. Using contemporary technology provides the adaptability and growth potential needed to stay ahead. Technologies are re-used between variants and platforms in order to minimize Life Cycle Cost (LCC).

“In our partnership, the transfer of technology will secure an indigenous Indian capability for series production, maintenance, repair and overhaul capability. Testing and development of the fighter sensor package will have synergies with the systems developed for Gripen,” says Anders Carp, head of Saab business area Surveillance.

Saab has a proven background in tailoring systems to customer needs. This brings extensive experience from having open relations with customers when adapting advanced systems to new platforms.

“Saab is a world leading company in the sensor area and has equipped some 4500 fighter aircraft with radar and electronic warfare systems. This has given us wide experience of successful sensor system integration, testing, and evaluation of radar and EW systems on fighter aircraft,” says Anders Carp."

Uttam AESA radar details


1. Each TR module is 10 W working at 1 GHz (X-band). Four TR module per "package"
2. When they went for volume production, components (power amplifier) were denied. The speaker calls it blessing in disguise

. They had foreseen this and had started co-development with Astra microwave ahead of time. Last year, they qualified the indigenous QTRMs. BEL and Astra have already developed more than 4,000 units. The QTRMs are being used for 3 other strategic ground array systems.
3. Planks are packaged using vacuum brazing. They started with debrazing but could not qualify it inspite of many iterations. The vacuum brazed package works very well and has been indigenized.
4. Exciter/Reciever module: indigenous and qualified
5. Array power supply unit: indigenous and qualified
6. Cooling unit: indigenous and qualified
7. Complete array has been recently qualified. Safety of flight qualified. Ready for installation on the aircraft.
8. +-60 degree
9. Range: 115 km (subjective). Can be increased or decreased based on cooling, space and mission requirements.

10. Roof top testing done for qualification. Criticality lies in the software. Mission objectives need to be defined properly.
