LCA TEJAS MK1 & MK1A: News and Discussion

[ersakthivel]

Your observation isn't... incorrect.
To get any more than this you'll need TVC, or atleast canards. But in some moves ITR of Tejas here almost matches Rafales's. STR lesser than that but comparable to F-16 or Gripen. Even some of Eurofighter Typhoon's moves are similar.



Anyways we were pointing out how the demo have got more aggressive & flashy, with more rolls & short sharp turns. Earlier it was kinda shit with some same basic maneuvers being done.

Typhoon takes 10 seconds fr many vertical half loops and 20 seconds approx one full vertical loop typhoon in this video, Rafale too has approximately the same timings.

Tejas too has same timings fr its vertical loops in bahrain airshow and many other airshows,
even in the 2021 Aeroindia show clip Tejas pulls a half vertical loop in 10 seconds approx,

So low wing loading of cranked Tejas is upto the mark in vertical loops despite the fact
Typhoon has way higher thrust to weight ratio than Tejas.

Tejas also has good ITR roll rates and can do negative G loops

In horizontal loops I havent seen Tejas bettering 23 seconds timings, Typhoon ,rafale hv way lower timings than Tejas in his dept,

No Bahrain was a much better show than anything other than this aero india and airforce day shows...with all these displays,Tejas was showcasing its ability to perform maneuvers(with no sweat) rather than pioneering agressive maneuvers,those will be displayed only in the future when Tejas establishes a substantial market.....

Agree

Distracted by CATS, most people failed to notice, that this was the first mockup of dual-rack CCM pylon for Tejas Mark1A.

View attachment 77562

that give 4 BVR missiles (two multi ejector rack,
3 CCMs ( 2 in one multi ejector rake, another pylon housing SPJ and one CCM
A centerline drop tank, capability,
good to hv in CAP roles and QRT roles

The SPJ & CCM dual-rack has been rejected due to drag. Only this setup is found to be optimal.

I have done the measurements their teachers does not have enough space to hold a dua-racked BVR & CCM side by side.

Theoretically, Tejas could carry a config of SPJ–2×BVR–EFT–EFT–EFT–BVR–2×CCM
Is look weird, but be its max possible A2A loadout.

First flight of sp24??

LRU alterations done I read a comment of Twitter... Redoing the equipping again.

What did the writer say that was anti-India? Indeed, he/she was extremely critical but criticism is not propaganda.

 

[Ghost hale]

Any updates on tejas FOC induction dates?

Basically lauds gripen muh f16 as if Tejas can't handle them or arnt better than them

Criticism?!!

Fucker just makes random baseless statements out of his ass. Have you not read the crap?..

"For example, the LCA has endurance of 59 minutes per sortie versus two hours for the Swedish Gripen Jas-39 or the U.S. F-16. The payload of LCA is three tons versus six tons for Gripen and seven tons for the F-16. Worst of all LCA was found to be less reliable & required twenty hours of maintenance for each flight hour versus six hours for the Gripen and 3.5 hours for the F-16."



Plus "writer" doesn't understand shit. Example:
Like Tejas has MTOW of 13500kg, Gripen 14000kg, empty weight are 6500kg & 6800kg... Fucker says Gripen has 6t payload!
Without full fuel & on the ground its wings can attach that much, Tejas can have 3×1200, 2×800, 4×150 or 4360kg.

This shit has already been rebuked very well before by DDR.

Int. Fuel+ ext. Fuel 2400+2400+725=5525kg
But ferry range only 2200km how can it possible

Int. Fuel+ ext. Fuel 2400+2400+725=5525kg
But ferry range only 2200km how can it possible

Firstly your figures are not standard between litres & kilograms. 1 litre Tejas jet fuel is 0.8kg.
Correct measurement is, 2400kg(3000lt) internal, 2× 960kg(1200lt) wing, 580kg(725lt) central tank, total 4900kg(6125lt).

Anyways external drop-tanks have significant drag & are not jettisoned in a ferry journey... Plus present central drop tank is rarely used as it is so draggy it only adds less than 200km to net range. Only the drag optimised 710lt one will be used in future.

This is Tejas after an actually ferry.

Those old fake claims being written over and over.

"For example, the LCA has endurance of 59 minutes per sortie versus two hours for the Swedish Gripen Jas-39 or the U.S. F-16.

Worst of all LCA was found to be less reliable and required twenty hours of maintenance for each flight hour versus six hours for the Gripen and 3.5 hours for the F-16. "

1. Comparing Tejas mk1's endurance with internal fuel, vs Gripen E's and F-16s endurance using drop tanks.

2. Tejas mk1 has already demonstrated external payload over 4 tons+. Now if you look at Gripen E on wiki - Empty weight - 8 tons, internal fuel 3.4 tons and max take off 16.5 tons. That leaves external payload at around 16.5 - (8+3.4) = 5.1 tons. Infact it would be even lower by another 300-400 kgs considering the pilot and his equipment also take up weight.

3. Tejas 20 hours of maintaince after each flight? During ex Gagan Shakti 2018, EACH Tejas was doing 6 sorties a day. So unless each day has 120 hours, thats not correct.

Check at 5:20 timestamp. F-16 needs 10 hour of maintenance for every one hour of flying as told by the F-16 pilot. Of course it must be avg calculation on total flight hours.

Watch Pentagon wars , it's a insightful look inside much positively acclaimed MIC of America .
It's a movie , basically about development of bradly ifv, took 14 billions to develope.

Yeah, that's very very misguiding. Just a comedy.

Is it really a comedy ? I mean sarcastic but not comedic .
Plus Bradley performed superb due to the very reason as shown in that film.
I might be wrong but as wikipedia says ( unreliable alert ) the cost of whole programme in year 2000 was around $5,664,100,000
