LCA TEJAS MK1 & MK1A: News and Discussion

[patriots]

Design Change:

Structural changes.
1) Nose cone is sharpen for better aerodynamic performance.
2) Wing blending improved with fuselage for better lift and reduction in RCS.
3) Canopy elevated to improve Aerodynamic performance and improve acceleration.
4) More composites shall go in outer surface to make plane lighter in weight and reduce RCS.
5) Duel missile racks to carry More missiles.

This will result in:
1) Improvement in MTOW by 300 kg due to lift coefficient which is an excellent outcome.
2) Radar cross section shall decrease further because of more composites and design tweaks.
3) Transonic acceleration and highest speed shall improve a lot.
4) Farry range is improved because of aerodynamic changes and ability to carry more fuel.
5) STR shall be improved to 18* .
6) AOA shall be improved by few degrees because of tweaking of wings.
7) Weight carrying will increased by 500 kg.
8) It shall be much more maintenance friendly aircraft with easy accessibility to many LRUS and low maintenance.
8) It will have hot air refueling and OBOG as well.

Electronics , Weapons and communication and net centric warfare capability.

1) UTTAM is planned now planned in MK1 instead of ELTA 2052. This will open the way for integration of METEOR. AMRAM is planned as the short range missile. ASTRA shall be incorporated with MK1 till ASTRA MK2 and SFDR missile arrives. It will carry 2 missiles in missile rack on each hand point.
2) It will have net centric warfare capability by which Tejas shall be connected with 40 other planes with Net centric integration and shall be able to communicate with other planes in a secured DATA link.
3) It will have a state of art EW mounted outside the planes. Gun position is also changed slightly for better arrangement of external payload.

So new Tejas will be more faster, more maneuverable and will carry higher payload. I It will have top class AESA and world's best WVR and BVR missiles with very low RCS and very good EW and ultra long range AAM. Tejas mk1A is a very good plane getting even better and shall be more than a match with India's enemies can come up within coming decade.

Bdw how mk1a will be carry more fuel......

It will have air to air refueling anyway.

Not the right argument.....
Foc will have ifr too

Foc has ifr. Very good . I was ignorant about it .
Mk1a will probably have bigger fuel tanks as LRU rearrangement will open up a bit more space. But it's just a guess.

I believe if ada will be able spj and irst within............it.....then it will be a great achievement

Sweet.. Where did you find the raised canopy thing?

Upgraded cockpit?

.......

Mk1a will probably have bigger fuel tanks as LRU rearrangement will open up a bit more space.

Can you elaborate how? It's basically that same platform....

I believe if ada will be able spj and irst within............it.....then it will be a great achievement

The Mark 1 & 2 has very similar nose area, squeezing the IRST on the Mark1A shouldn't be impossible.

 

[HariPrasad-1]

Fuel tank is right behind the canopy. If canopy is raise from current height, it will release more space behind the canopy. This will allow Tejas to carry additional 60 kg fuel.

 

[HariPrasad-1]

Sweet.. Where did you find the raised canopy thing?

It is very much there on many forums and open sources. Please read the article of indranil roy on delhi defense review. Same is posted here on the same forum as well.

It should mentioned that current mk1 itself has ferry range of 2000+ km as written in article of Delhi defense review by indranil and jayes.

Ada figure for mk1 are very conservative.

So for mk1a to have 2000km+ ferry range is no surprise.

No space for them unfortunately as of now.
External spj will come and to compensate for pylon dual rack missile launcher will be added.

USA added irst to central drop tank of f-18 iirc.
We could also do something like that later on.

Ya..knew that.....hope ada will do something.......to put them inside ..,.at least...spj

Uttam GaAs MMICs AESA. 768 TRMs. Each TRM arranged in modules of 4x TRMs, at 10W each.

If the cooling system allows you to use it at full rating, that's 7.68 Kw, 20% duty cycle would give you Pav of 1.5 Kw, 10% would be 768 W.

Bdw...waiting for the when tejas will be able to carry brahmos mini

It's indicative for mk1. Most likely only MWF will be able to carry brahmos mini.

736Trm, 182quad trm... The BEL supplied rates 8-10 watt, the astra microwave supplied rates 12 watt... Moreover this radar will have better gain, and least side lobes, when compared to circular arrays of similar radius...

Mk1a will carry bramhos mini. It's inboard pylon can already lift 1200kg while bramhos Ng will weight 1500 kg. So with some hardening mk1a will be able to carry 2 bramhos Ng.

Do we have stats for elta 2052 and RBE2 aesa?

Do you have a source for that weight? According to this article (https://www.financialexpress.com/de...-next-generation-brahmos-ng-missiles/1512331/), the Tejas should be able to carry the BrahMos-NG

No bro....mk1a will be able to
Coz in our lima 2019 poster we had a photo of tejas with 2 brahmos mini(artistic)
We are offering mk1a so

If so. It will exceed Gripen E in capabilities and in MWF avatar it will kick its ass...
And I will be doing
