Elta Systems will supply the radar for all future versions of India's Tejas light combat aircraft (LCA), after the Israel Aerospace Industries (IAI) subsidiary was selected by Hindustan Aeronautics (HAL).

The company's ELM-2032 fire-control radar is installed on prototypes of the Indian-developed fighter, and deliveries will continue as series production starts. According to Elta, it also has been chosen as sole supplier for additional future versions of the Tejas; Israeli sources suggest this could involve using its active electronically scanned array ELM-2052 sensor. They suggest that strong ties between HAL and IAI could see additional Israeli equipment installed on the fighter.


India's air force has announced plans to order 80 more LCA in an improved Mk1A configuration, following an earlier order for 40 Tejas jets.

===================================



Meanwhile LRDE's Uttam specs displayed at Defexpo were 150km (up from the original 100km).


Sir, can this be shared again.. not finding it. Sorry to bother u again.

===============

There are no Winner or loser, It matters what its design to preform according to given requirement by IAF ..

Maruts were also raised at Sulur ..

In other words, you actually admit that without all these LCA Tejas is not a winner .......?......!

Sulur is not far from Bengaluru.

May be that is why they prefer it for initial time being.
No I what I am saying is very much achieved and exceeded in Gripen C. They will be achieved in LCA MK1+ also.

Now, if we have a single piece part made by the traditional method and then by 3D printing, both will weight the same. Specific gravity of a metal will be same in either case.
In aeronautics, it is a bit tricky. Weight varies with altitude. An aircraft or any object weighs a little less at 70000 ft. than while on tarmac. In day to day life we consider mass and weight as same, although it is wrong. Weight includes both mass and gravity and is indicated in Newton. Mass is the amount of a particular material measured in kg/g, but does'nt take into account gravity. Still we say a kg of rice!!..assuming, the rice will always stay at ground level :tongue:. That is why it is better to go by mass rather than weight in precision manufacturing. You are right when you say both the parts will weigh same at ground/ sea level, because both have same massess of same material whether forged, cut & ground or 3d printed.
I think the reason why it is lighter is because what used to be many parts, is now a single part. If you have multiple parts bolted or welded together, that will obviously increase the weight.
The same thing is claimed in the video clip. GE used just 1 part to 3d print the nozzle instead of 20 in traditional manufacturing, resulting in 25% reduction in weight ! Now, the dimension of the nozzle has to be exactly same whether 3d printed from aluminium powder or welded together from 20 smaller pieces of forged aluminium parts. And we all know if the dimensions of two objects are equal, they will weigh same, provided they are manufactured from same material. I have searched an explanation for GE's claim but could'nt find.

@sasum, you are correct.

Weight is force, and is measured in Newtons. Mass is measured in kilogrammes.

Weight of a given mass is determined by the inverse square law. The further the two centres of gravity (in this case, that of the part and that of the earth), the lesser the attraction between the two masses.

If the part goes up in the sky from the ground, the force will decrease by the difference of the two inverses of the square of the distance between the two centres of gavity.

Do we have 3D printing machines in India ? Do we also use them ?

I can't understand, how NLCA even in its Mk-1 version is not aiming for an IRST. Something like the Skyward should get crammed into the cockpit space. It will need some rearranging but there is enough excess space behind the pilot seat.

Saab keen to partner with India for next version of LCA Tejas

Saab is in talks with them to finalise the latest avionics and radar system for the Tejas 1A, the version of the indigenous plane.

Even though India has scrapped the earlier multi-billion contract for 126 Medium Multi-Role Combat Aircraft (MMRCA) programme and decided to go in for only 36 Rafales, the government will select at least one more aircraft besides Tejas to be built in India. (Photo: PTI)

New Delhi: Swedish defence major Saab is keen to partner with India for the next version of LCA Tejas even as it has offered its own newly-launched Gripen E fighter aircraft under 'Make in India' initiative, but with over 49 per cent stake in a joint venture with a private firm.

Based on a Request for Information released by state-run Hindustan Aeronautics Limited, the makers of Tejas, Saab is in talks with them to finalise the latest avionics and radar system for the Tejas 1A, the version of the indigenous plane that the IAF is interested in.

"Yes, we are in talks with HAL. We have the latest avionics, best active electronically scanned array (AESA) radar and technology in the Gripen which we would be happy to share with HAL for the Tejas programme," Jan Widerstrom, Chairman Saab India, said.

He argued that it will be a win-win situation if the Indian Air Force (IAF) decides to get Gripen also. "From a user perspective, maintenance, knowledge build up and Make in India, this will have lot of advantages," he said. Asked if the offer to help the Tejas programme was conditional to IAF selecting Gripen, he said both are independent programmes.

He also made it clear that Saab is looking at more than the automatic limit of 49 per cent FDI in defence in the joint venture that will make Gripen in India. Under the rules, a company can seek even 100 per cent FDI if it brings in high-technology under the 'Make in India' initiative.

Even though India has scrapped the earlier multi-billion contract for 126 Medium Multi-Role Combat Aircraft (MMRCA) programme and decided to go in for only 36 Rafales, the government will select at least one more aircraft besides Tejas to be built in India.

Defence Minister Manohar Parrikar has said that India will decide between American F-18, French Rafale, Eurofighter Typhoon and Gripen by the end of this fiscal. Incidentally, IAF chief Air Chief Marshal Arup Raha visited the Saab facility in Sweden last week and even flew the Gripen.

"Our concept of technology transfer is real as we are willing to give India comprehensive systems and software control. In short, Saab is not only looking at setting up a base here but also helping in the development of aerospace capability for many more years to come," Widerstrom said.

He added that Saab will not simply move an assembly line but will build development capability. "We will design, develop, produce and maintain in India," he said.

India a responsible N-power, needs no lessons, says Parrikar

Defence minister Manohar Parrikar on Tuesday said India would not change its nuclear policy under any circumstances.

Addressing the media, the defence minister said the ministry had given a no-objection certificate for according commercial status to the Adampur defence airport in Jalandhar district. “The Airports Authority of India and Air India are holding a meeting in July to finalise things,” he added.

He said India was a responsible nuclear power and did not need any lessons from the external forces. Replying to queries about Pakistan’s threat of a nuclear war, he said India knew its job well enough.

Parrikar said Pakistan was burning its own hands in the fire of militancy. “We are equipped to counter any attack and give a befitting reply to those who want to destabilise the country,” he warned.

Responding to the recent Chinese intrusion in Arunachal Pardesh, Parrikar said the country’s defence forces were keeping a close vigil on the situation. He, however, said that the overall cross-border infiltration had come down in the recent past.

Talking about the Union government’s “Make in India” initiative in the defence sector, Parrikar said that indigenous Tejas had been inducted and a proposal was afoot to manufacture twin engine fighter aircraft in partnership with a foreign company.


Refusing to speak much on AgustaWestland chopper scam, he said the previous UPA government had flouted established norm to strike the deal and the matter was under investigation. The allegations of Congress president Sonia Gandhi’s sonin-law Robert Vadra’s links with an arms dealer were also being probed, he added.

Very confusing set of statements coming from ManoharParrikar.

Raha fly both Tejas and then Gripen.

I see Gripen as a threat to our LCA program as both are single engine fighter.(100 Gripen means 100 LCA less)

SAAB is a back up option, If HAL fails to deliver its projected manufacturing rate for Tejas ..
Sir, if HAL fails to deliver on only production rate, make a new line by India private company OR force HAL to outsource most of the work.. Saab is a Bad Bad idea.
Tejas mk1 itself is good enough to be produced in large numbers.
