LCA TEJAS MK1 & MK1A: News and Discussion

[darshan978]

Breaking...Order of 83 Tejas Mk 1A is finally placed

"Akhir kumbhar gadhe pe bethega hi" a famous saying
Iaf will have to buy tejas in numbers
No option exept supporting own product rather than shelling our billion at other products...

Actually that's very underwhelming (expect a few moments), almost lazy. Watch Mirage-2000 maneuvering.
Tejas did much better in Bahrain Airshow! I'm guessing this guy got the ride only in 2017-18 & don't have many hours in it yet.

Agree, LIMA performance was OK compared to Bahrain. But LCA was flown by a test pilots during Bahrain while this time it was flown by a regular pilot with limited flight hour experience. I expected more this time, but then regular pilots are not display/stunt items.

I think Mirage can out-maneuver LCA very easily, especially at high-speed and the biggest point is that, which lets down LCA, is the drag which it generates. Ironically the more draggy jets are highly maneuverable but in LCA's case, it is not so maneuverable. Probably ADA is trying to limit the flight profile as they are not very confident about the Control Laws yet.

There is a committee working on to reduce the cost. But the $ 63 million is derived by dividing the number of jet to the total quoted project cost, which doesn't gives the complete picture.

Lets wait for the committee to release its outcome. There are very few solutions available to HAL & MoD.

1. Avoid some foreign sub-systems, which can be produced locally, especially Israeli.
2. Use UTTAM AESA instead of exported one, Uttam should be made flight worthy within 2 years to make it possible.
3. Increase MK1A orders to 123 from just 83.
4. Produce/Assemble GE-404 locally.

This will help in reducing the cost by $ 4-5 million per piece.

About 5% decrease in cost......................will also come at a 5 year delay in production!!!

Assembly plant for 83 engines?? Ridiculous! Also, these are not decisions that desi babus can make....GE has to agree to it.......not to mention the time it takes to set up the manufacturing facility.

Also, locally assembled/manufactured stuff often comes out MORE EXPENSIVE THAN OFF THE SHELF products!

I've seen Tejas take impressively sharp turns from time to time, should be always like that!
Like in this video from Lima itself, practice day:
^It did a 16 sec loop at 0:33!
^See the (-)G turn at 1:55 or one at 5:50!

Maybe it's a bit limited by its 8G, but that final day's performance was just... bad, for some reason. Dude probably found free exotic food & ate too much for breakfast.

Nah. I've seen Tejas take equally impressively sharp turns from time to time, but not always for some reason!
Like in this video from Lima itself, practice day:
^It did a 16 sec loop at 0:33 & 7 sec 180° at 0:10!
^See the (-)G turn at 1:55 or ones at 1:10, 3:35, 2:40, 5:50!

check this out .... we know Kaveri already, and now there is Ganga as well. some food for experts

That's A new thing we got to know.
Let's try to find new things about this "Ganga" project.

Nothing happened. Ninja Monkey mistakenly posted wrong news link, I didn't check.

Ge is offering a new engine with 110 kn thrust.....for amca...and mwf
But we shouldn't stop our research.....

Will happen after election I think.................

What do you mean?

...till it starts manufacturing 83 Light Combat Aircraft Tejas Mark 1A fighters by 2023.

“We expect the order for 83 Mark 1A LCA Tejas fighters in one or two months,” the HAL CMD further announced. The problem is that the Mark 1A variant has not yet been developed. But HAL believes that this is not a big hurdle, now that Mark 1 has been certified for combat capability with a Final Operational Clearance (FOC). The Mark 1A variant requires retro-fitment of an AESA radar, and expansion of the avionics envelope.

It's good that Mark 1A order is about to be placed soon, but FOC Tejas delivery is expected to end by 2020-21 fiscal.
That means the 2 Tejas lines meant for filling IAF squadron s are going to sit idle, even it gets export customer/s... unless more FOC Tejas ordered.

If they'd start production in 2023 (planned 1st flight in 2021-22) that means Mark 1A is to have constable alterations to the airframe that need to be tested.

I mean.....dac has not cleared procurement of....mk1a....

My post was a reply to a Twitter post which one says mk1a cleared.....

Hi


Was referring to MTOW. But yes the concern is still like ~40 percent increase in mtow would f414 thrust increase ~18 percent, be again underpowered?

The fighter requires more engine thrust in close combat ( no external stores & half fuel mode)

Also some drag reduction & increased length in Tejas mk2 means better lift to drag ratio,
higher length allows Canard placement which will add further to turn rates,
h
which also increases its load carrying range & close combat specs like ITR & STR, AOA Gs pulled in the same no external stores & half fuel mode

As far as MTOW is concerned you can compare gripen E's MTOW & engine thrust as both tejas & gripen hv almost same engine thrust & MTOW both in Gripen C/D-Tejas mk1 versions

&
will also hv the same combo in Gripen E & tejas mk2 version.

Its enough if Max thrust is able to lift MTOW at ground level.

Is this Maitya's chart from Bharath rakshak?

 

[rohit b3]

They are simply sitting on the Tejas mk1A deal so that they can cry about "Squadron shortage" and blame HAL for "Delays" and then buy more Phoren maal.
