This bit caught my eye

LCA-Tejas recently received major upgrade to its software blocks which allowed it to pull beyond 8Gs and cleared it to perform manoeuvres which were never seen before.


I may have missed this bit when it would have been discussed here, since we have members attuned with the LCA programme. But was it only due to software upgrades, or hardware and engineering upgrades as well?

^^ The article is a misnomer.

The software was not "upgraded" in the true sense, but it was "upgraded" so that the codes which kicked in limiting Tejas under 8G was removed.

So yes any process of downloading a new version of software can be thought as 'upgrade' from process point of view. But from system point of view, certain functionalities which were covered are now being uncovered (that is the burqa is taken off).

Or put it this way, Tejas is now allowed to go and kick-ass. The low fly and the vertical climb and then a flip and circle back is sheer joy to watch.

Tejas is in a class of its own!

this will permit more space for internal fuel and avionics.

I think the Navy Mk 2 version has this.

you are right. it is very over engineered and efforts are on to cut it down. even the far heavier hornet may be ok with the current gear.

can anyone estimate at what speed this display is being flown? is it done at the max corner velocity (ideal for tight turns and limited airspace)

Nitin Gokhale is in Bahrain. From his twitter feed

Tejas pilots will do a Square loop, two rolls, a steep pitch up, a low speed pass combined with half roll and a loop ...

flying is scheduled for post-lunch sessions every day. Probably between 1300 and 1600 hrs

Commmoder Jaideep Maolankar & Gp Capt Madhav Rangachari will fly the Tejas at the Sakhir in Bahrain later today

Arn't these the same guys who worked on the 8g+ tests. Great to see the snippets of the displays. Sad to see no news of this on any desi 'News' Channels....

I studied this some time ago and my memory is foggy, but let me still give it a try. When it starts turning, it would turn at corner speed attaining max possible turn rate ie ITR but it cannot sustain it for too long (unless it doesn't mind bleeding off too much energy) and it will go down to STR which it off from corner speed. It would move down on V-n diagram along the stall line IIRC.

^^ so pakistan AF is forfeiting $500,000 for booking space at air show. If so, then surely they have chickened out due to lack of confidence in their platforms in respect of direct competition with 4+ and 4++ gen fighters it will share stage with.

For those of us who don't know better, it would be great if someone took the time to summarize what it is that's new we're seeing here in terms of Tejas capabilities that we did not know before, or suspected but could not confirm? Thanks gents.

the M2000-9 definitely looks faster and more slidier than the F-16-block60 in the air. 28 degree AOA , 95 knots slow fly by

Read its advantage of Compound delta wing but in a turning fight with F-16 , M2K will quickly loose its energy

Any commentary guys? 8)

We might catch the tail end of the Sarang display and hopefully all of the Tejas display.

http://economictimes.indiatimes.com/news/defence/full-scale-production-of-tejas-by-next-year-defence-minister-manohar-parrikar/articleshow/50668656.cms?utm_source=contentofinterest&utm_medium=text&utm_campaign=cppst

NEW DELHI: Defence Minister Manohar Parrikar today said full-scale production of the indigenous Light Combat Aircraft Tejas will begin by next year and that other countries have shown interest in the plane.

"As per my primary report, it is appreciated by other countries who are interested... By next year, we are starting full-scale production," he told reporters at the NCC Republic Day camp here.


Tejas, which had been in the making for over 3 decades, is taking part in the ongoing Bahrain International Airshow as the country hopes to explore potential export opportunities.

The training of IAF pilots on LCA has already commenced.

Though DRDO has developed a naval version of Tejas, the navy is seeking a more powerful engine, besides other changes.

As per the production plan, six aircraft will be made this year (2015-16) and Hindustan Aeronautics Limited will subsequently scale it up to eight and 16 aircraft per year.

It is estimated that 20 aircraft will be built by 2017- 2018, to make the first squadron of the aircraft.

The LCA programme was initiated in 1983 to replace the ageing MiG-21s planes in IAF's combat fleet but has missed several deadlines due to various reasons.

As India aims to market Tejas, it will face competition from Pakistan's JF 17, built in collaboration with China.

The aircraft has already been placed in the open market and it was speculated that one of the Asian countries had evinced interest in the aircraft.

However, Sri Lanka had recently denied reports that it had evinced interest in the Pakistani plane.
