LCA TEJAS MK1 & MK1A: News and Discussion

[patriots]

@patriots These are interesting... I too have wondered why can't LDP be replaced with SPJ & IRST.

See what you can find from AK & HVT. You're the guy for this.
I thought the same damn thing, or atleast similar.

My idea was to use a NLCA NP-2 like concept on Mark1A to make extra room, without need for drastic redesigning. That's why I've been asking around if two-seater Tejas has more drag (a dealbreaker) or not.View attachment 43070 View attachment 43068

Naval Tejas is heavier than iaf tejas
And it's speed is restricted too.......lower than iaf tejas
Tejas is already heavier,more fuel will reduce its performance...
Tejas mk1 will be based in Tami Nadu
Mk1a may be based on forward bases
Tejas is smaller in size can't expect much
Do u know hal experimented with plug(to increase length)....study showed increase in drag ,but not the same with performance

Wait for mwf ...all shortcomings will be cleared @Bleh

Again Ada will integrate spj on a outer pylon ,to use the spj in maximum potential
(Answered by nileshjrane)

Though jf17 carry a spj just below it's intake

I know, you told me... Can you ask why we aren't doing the same?

Tejas can carry IRST pod there too. Why not that?

That's because of NLCA's reinforced undercarriage & beefed up landing gear... Which is why they had to remove the second seat & make room for equipments.
I'm talking about doing the same for existing AF Tejas trainer (you told it has no extra drag, but better area ruling), except making room for enlarged fuel tank by lifting the avionics.

It'll have to carry that extra fuel in external tanks anyway, to maintain operational range... instead this can free up two pylons to carry 2-4 more BVRs, well within load capacity.

Because that's not the most effective way. Read Delhi defence article on mk1/mk1a and you will see why .

No one has denied that! Let us first build an irst pod. We'll see how it works .

 

[Suryavanshi]

Might be off topic or maybe just plain dumb.

Is there any way to integrate aircraft with Air defence system.

I mean suppose the S 400 radar detects a Incoming Airplane can It relay information to the aircraft nearby for interception and vice versa.
A sensor fusion basically.

 

[Veiled V I P E R 2]

Assumptions assumptions! Don't AFAIK without having solid info.

No one knew the range of Derby and if you think any company will release actual range for such sensitive tech is sadly mistaken. Moreover, Indian variant is I-Derby and not the older one.

Lastly, 45SQ can fire it, they received s.w update back way back in 2018.

Brother, No. 45 squadron armed with IOC II MK1 which can't fire BVR as of now. You may cross check. Those IOC airframes can withstanding only upto 7 G and these 16 Tejas don't have Canon too.

Why would I cross check? Thats govt official post not some layman with AFAIK. Maybe you are above govt that question their official statement.

Second there is no diff in build of IOC and FOC structurally, IOC are capped at 6G manuevers and not 7g. That too is a s.w limitation and not structural. Infact, Tejas test a/c did 8g loop during Bahrain Air show. Also G's has nothing to do with BVR missile firing if thats what you are implying.

Govt statement said BVR-firing is a requirement of FOC Tejas... & that was achieved, by LSP7 firing Derby, but after SP-9 was rolled out.

It's possible ofcourse but do you have a concrete confirming source source for claiming that all (or any) of those 45th Sqdn. IOC Tejas can do so as well after this apparent software update?

What's your source for classifying there's no structural difference?
It was said about FOC Tejas "integration of air-to-air refuelling probe and associated major hardware (structural modification) and software (flight control software) modification".

What's with the aggression!.. Govt statement said BVR-firing is a requirement of FOC Tejas, & that was achieved, by LSP7 firing Derby.

Read before commenting! Most people suffer from this disorder. I provided the source already.

Based on the successful integration and demonstration, Regional Centre for Military Airworthiness (RCMA), a unit of DRDO has cleared the series production aircraft of Squadron 45, to be equipped with Derby operational capability. LCATejas has successfully completed a series of captive flight trials to clear Derby for the full operational capability in the entire FOC envelope. In the past, Tejas has qualified for the armaments and missile release related trials.

The above was in 2018.

Structural means the air frame here, A2A is mostly internal plumbing the only external source is the drogue which doesn't constiture much and won't impeded on flying capabilities. A2A was not meant for FOC it was brought forward to compensate for other leeway given by IAF. A2A was for Mk1a but now comes with FOC too.

As I told you in helicopter thread, FOC is mostly s.w related adding more capabilities, weapons etc. Sturctural improvemnets will only happen with Mk2. Everything else in FOC/MK1a is internal readujstment and doesn't add or sub the cabailities of G manuevers in simple terms flying ability.

Read it... Not talking about planning. We know it can be done, but has this software upgradation actually happened?

Some software modifications happened
But software modifications for bvr carrying happened or not
Not known to me

This is what Network centric warfare means.

From BRF by jays.

Fanne sahab, no need to hyperventilate. If you put half the efforts you put in writing these long posts, in tracking tenders or asking question to HVT on teeter, you would know better and have more peace of mind. Mk1A has a overhauled DFCC with elements from MWF bring it to at par with MWF, done mostly. A huge upgrade. Req was spelled out for SMFD instead of MFD ages ago, looks small change but a lot will happen behind the panels (we had a discussion on it here some time back). A full scale testing rig for entire aviation suite testing and verification is in making. 2052 integration going on in parallel. Uttam progressing. I'm sure many more activities are underway like weight optimization, LRU layout reconfiguration etc.

We shall soon have the milestone of 5000 accident free flights.

Guys recent ly Ada said(in Ananth k m s video around mwf) that mwf will be only fighter in iafs inventory to carry 8 bvrs
Then do u all have any idea how many bvraams can carry other fighter s in iaf
1.tejas foc(2bvrs ,seen upto now)
2.mk1a(4 bvrs,said by @hvtiaf)
3.su30 (6bvrs)
4.rafale(6bvrs)
5.mirage 2000(4 bvrs)
6.mig29(4bvrs)
7.mig21 bison(2 bvrs )
Data...I got from different photo s available in internet....
Happy to be corrected

Mk1a and foc lca are same airframe and both can carry same amount of missiles.

LCA can easily carry 4 bvr (astra - derby ) and 4 CCM ( r73-asraam) with dual rack for mk1a.

Also there is no weight limits in pure air to air configuration and we may see dual rack bvr pylon from mwf being adopted for mk1a.

Remember mk1a inner pylon are rated at 1200 kg and being improved to 1500kg for bramhos Ng .

So they can easily carry multiple bvr when dual rack comes.

For the rest numbers may be higher.

I believe Tejas can carry upto 5 bvrs
4 in inner hardpoint s ...1 under belly
But recently harsh vardhan thakur said that only mk1a will be able to carry 4 bvrs with one fuel tank(in center mostly)....
So here is the confusion....
If mk1a will carry 4 bvrs in 4 inner pylon then definitely will carry 2 ccms in outer hardpoint s.....
But not the case for foc

 

[patriots]

So. .hal can make 16 tejas per year.................

If you use centre tank there can only be bvr on 4 inner pylons. Hence 4 bvr. Outer hardpoint will have dual rack pylon for ccm so that one outer pylon will carry spj and other will carry 2 CCM.

So a typical air to air config will see.
4bvr + 2 CCM+ spj + centre line fuel tank.

Foc LCA will miss out on dual rack CCM for now but will get it later. Anyway all MK1 will be upgraded to mk1a in due course.

And multiple rack for bvr will come too.
