LCA TEJAS MK1 & MK1A: News and Discussion

[FalconSlayers]

100% independence is something unacievable right now , drdo must integrate them for sub system , that's the best way

I know hwnce we need atleast a few defence sector unicorns for independent projects, the reason why US and Russian armed forces are so efficient is because of indigenous defence industry with independent programs of different companies.

Tonbo , idea forge are two such companies wo have orders right now , others i don't know

I can't fund any data kn it's valuation , that's why didn't quoted it

 

[Ghost hale]

ASRAAM, derby tested.... i-derby, mica, R-73, Astra mk-1, brahmos-NG and SAAW to be tested for tejas MK1 and MK1a.
Astra have minimum range in few KMs but cost to use is considered for everything.

MKU and Tonbo can easily become Unicorns in less than a decade, can’t say about others.

 

[Flying Dagger]

It does now (which is likely to be the "NG-CCM" we'll induct standardise over the fleet to replace R-73)...

I frankly don't know why they didn't go with this originally. Its predecessor had TV.


Enters trial in 2022.

It's not as of now and neither we got it for ourselves in the batch already ordered.

The link is removed.

Probably cost is the reason not offered in the beginning though they have been saying abt it for over 2 decades.

MICA and IRIS T have TVC that inc the cost too.

But Mark2 probably can't be used at short ranges... Hard no such indication. One thing unique about Israeli Derby is, that it can be used within visual range (atleast advertised so). It starts with active radar homing.

And I've heard Astra-IR is gonna be based on Mark1 which is lighter (range is limited to half its max range, meaning it'll have no shortage of energy to require dual-pulse...unlike ASRAAM).

Derby is enlarge version of python ( IR missile for CCM )
With ARH. It is preferred to use in 20-50 km range below which python takes on. What is the minimum engagement of Derby ER ?

IIR missiles are preferred for CCM as they are difficult to evade.

Astra mk1 minimum engagement range is 10 km if it gets TVC in future we will be able to reduce it further like MICA

The IR version if it's Astra mk1 size and weight (150 kg+) then it's not lighter in comparison to other IR missiles. The range of IIR missile is limited to 60 km max due to its seeker limitation like MICA IR (60 km max range )

Dual pulse will help it retain energy before it hits the target. But that doesn't mean it needs to be of Astra mk2 size or weight.

What is the minimum engagement of Derby ER ?

Not sure, but can apparently be used as active-homing CCM.

Astra Mark2 would be too long range (ie, large) top be used in this. I hope they'd incorporated in Mark1, either already or in future.

Do you think the Astra MK3 SFDR with reportedly 350-400 KM range will be huge in size Hence few will be available to carry and that too in our Flanker-H fleet only as only it has the Radar detection potential for maximum utilisation of Astra MK3 SFDR?

No, SFDR aren't necessarily that huge... nothing compared to size/weight of bombs.

Which Mig-21squadron was it that was supposed to get the first batch of Mark1A?..

View attachment 78754

Is it the No 51 squadron of the IAF?

 

[ersakthivel]

Only saw this post after i posted the one about STR and all. And after all that bullshit on TEDBF thread, i can't beleive i am agreeing with you on this one......but it is true....and its this manoeuvre that can indicate an ITR for the aircraft at those specific conditions and flight parameters....(not what you would get in real operational conditions)

And for all crybabies screaming 18 STR......sorry, not till mwf....

what bS on TEDBF thread?


some mis conceptions here

horizontal sustained turn rate has nothing to do with ITR,
Tejas scores very high on ITR,

SUstained turn rate is 360 deg divided by time taken to complete complete knife edge horizontal circle , WITHOUT LOSING ALTITUDE,

it was relevant in the spitfire era dog fight of turning into the circle of enemy and getting a gun kill.

with the avent of BVR missiles ITR is everything , ability to turn your nose fast and fire a WVR with HMDS cueing wins you the dor fight,

Tejas with very low wing loading scores very high here,

WIth HMDS cued missiles STR shortfalls are no longer life threatening fr a fighter,

plus fr the same power to weight ratio a delta wing always has a higher ITR and lower STR than staight or cropped delta high wing loading fighters,

the catch is STR difference is big only at ground level, at high altitude difference narrows,

as the famous interview with ex greek airforce chief suggests, mirage 2000 will always hv the first shoot advanrtage over f16 in most of the flight profiles owing to high ITR,

Greeks had both F16 and mirage 2000 in their fleet,

Tejas has ahigher thrust to weight ratio and lower wing loading than mirage 2000, so it will be far more effective vis a vis F16.

in many vertical manouvers tejas can excel any high wing loading fighter owing to vortex based lift at higher AOAs and state of the art fly by wire tech,

Also in negative G turns and low speed pass and many other manovers Tejas excels.

Aeroindia displays dont count fr STR calculation

because Bangalore airport is a high altitude one not a sea level field,

AND MNC fighter STRs are fr IDSA conditions, (certain temp, at sea level)

 

[ersakthivel]

No offence, but you saying some words don't make it true (You seem to not know that max-rate-turn requires to be atleast 270°)... Plus I didn't claim any STR value. Just pointed out the turn rate achieved in available footage. That's how observation works.

Anyways back to the original contended point;
We have footage of Tejas doing multiple sustained loops & turns at rates that hasn't ever been matched, or superceded (rarely even attempted) by F-16 or Gripen in any of their demonstration, at any speed or altitude. So logically... as per publicly avaliable evidence... Tejas's sustained turn rate is atleast equal, if not superior... to both of them.

Simple deduction.

You wanna claim otherwise?.. You know what do. GET. EVIDENCE.

Tejas displays the same timings achieved by rafale and typhoon in vertical loops even at high altitude Aeroindia Bangalore airfield,

but Tejas is yet to display a full knife edge 360 deg horizontal loop at any airshow,

whether they want to keep some secrets or they dont want to show shortfalls is any body's guess,

but in barrel rolls, negative G turns, vertical charlies, no fighter in IAF can sustain more energy than tejas barring Mig29 offcourse, which excels both in ITR and STR. thanks to very high TWR,

Su 30 mki uses thrust vectoring,

 

[ersakthivel]

What are you even talking about, I can't see tejas doing any manoeuvre superior to viper or gripen in any airshow.....these multiple turn, loop talk is just BS and nothing else.
There is nothing superior in any of those.
But whatever, i can do nothing else, if you choose not to listen to reason.

only rafale did 18 deg plus STR in bangalore is my guess,

mind you bangalore is 3000 ft above sea level,

cant compare gripen NG to tejas mk1, engine thrust is different

I havent seen any viper or gripen doing 19 second vertical loop , in any aeroinda,

if there is footage to show please post

tejas does that in bangalore (even with restricted flight envelope) effortlessly

 

[ersakthivel]

Why is abhijit against tejas, porkies and chinnis are shouting on his name.
Any idea

he is a fool, go read the #Thermocline and#ThinktankWaterTank hashtags on twitter

you will know that he is just an imposter

 

[Bleh]

It does now. Rafale induction ceremony, max rate turn.

footage on YT. look it up

also don't type like this it's a pain to decipher

 

[ersakthivel]

He thinks of himself as a huge devil's advocate! I have heard his points & he brings up some value shortcomings (albeit blown out of proportion & often clearly with no further research age rating some paid articles)... but according to him the way to overcome those are not further R&D towards MWF, instead ToTing his favourite toy.

he knows nothing abt aerodynamics, just reads fancy brochures and bluffs,

Tejas is built to dominate himalayan airspace , where high wing loading fighters cant grip the low density air to produce enough lift,

there tejas can hv them at its mercy because it has the lowest wing loading of all fighters plus vortex lift based on lower swept wing leading edge root , at high AOA.

Mitra guy is either too dense to know that, or he is acting as if he doesnt know that

Tejas can handle any stuff and it has enough enough dance moves in any furball to win

 

[ersakthivel]

AIM seems to make good points when talking about politics and have good knowledge but surely have many misplaced theories regarding defence.

I asked him a few fundamental questions on tejas aerodynamics in twitter and he just whined like a bitch in neat used foul language and blocked me,

He was shilling fr gripen then,,

he also abused @hvtiaf in mean terms

with CATSWarrior sensor fusion combo Tejas can kill any bird, is my opinion
