LCA TEJAS MK1 & MK1A: News and Discussion

[Bleh]

IOC Tejas did 6 sorties/day in Gagan Shakti 2018, NLCA did even more from Vikki. Tejas has twice the availability of the aircrafts it's to replace. In effect, a squadron of Tejas is capable of doing more sorties than 2 squadron of Migs & Jags.

Also in GaganShakti, Tejas "emerged with best range scores in terms of best weapon delivery by any aircraft fielded in the Gagan Shakti 2018" outperforming Jaguar & Mirage-2000 in A2G payload delivery.

Add to that its capability of hot refueling & quickest turnaround time, Mark1A will be working as both, an interceptor & a ground-striker.

Can we expect MWF to be rival of F 16 block B and C after it's matured?

I mean F 16 is a time tested product with over 25 years of improvements, its a single engine as well but way more powerful.

Ofcourse. MFW has a new generation frame so it will be better as platform. So far as electronics a d weapons is concerned, it will have those at par with the best. It has a exceptionally high T/W ratio. So in my opinion, it will be better than F 16.

 

[HariPrasad-1]

Any idea if there are enhancements on payload?.............

Yes, there is a increase in Payload as well by 200 kg atleast, increase in Highest speed by 2%, 20% improvement in Transsonic acceleration, ferry range which is increased to 2000 KM from 1700 km. etc. Even fuel capacity will be increased by atleast 60 kg. STR shall be improved to 18*.

 

[HariPrasad-1]

why would americans let it be competition to f16...mwf will b using american engines....

Because we have other European options.

HAL plans to outsource 35% of LCA manufacturing to private sector
MANU PUBBY
ET Bureau | Feb 4, 2020

NEW DELHI: Gearing up for its biggest order yet under the Make in India initiative, state owned Hindustan Aeronautics Limited (HAL) plans to outsource a significant part of the estimated Rs 38,000 crore contract to the private sector.

The leading aeronautical firm is in line to bag a contract to manufacture 83 of the LCA Mk 1A fighters — to be equipped with advanced radars, sensors and indigenous weaponry — and is doubling its annual production capacity to meet the requirement.

HAL chairman R Madhavan told ET that the first of the upgraded fighters can be delivered within three years of the order being placed and a significant amount of manufacturing will go to private sector companies such as Larsen and Toubro, Dynamatics, VEM Technologies and Alpha Design “We have planned that four vendors will supply major parts of the fuselage for the fighters. With regard to the manufacturing part, we plan to outsource almost 35% to the private sector,” said Madhavan.

Several other Indian vendors will also be involved in the project, he said.

HAL has put in place the infrastructure to double its capacity to produce 16 of the fighter jets every year and has a contingency plan to increase it further if the need arises. “The second (production) line has been set up. With two lines we can manage 16 a year for now, if really required we can put up a third line as well,” said Madhavan.

Even fuel capacity will be increased by atleast 60 kg. STR shall be improved to 18*.

What? Where are you getting all these from?

T/W at full weight

F16 - 13/19 = 0.68

MK2 - 10/17.5 = 0.57

 

[Bhurki]

Is there any news about signing of 83 Mk1a ? Any deal? Dates, rumours etc? Anything?

Be ready to get disappointed.......

 

[Bleh]

What do you mean by mwf here?
I mean specifications..

T/W at full weight
F16 - 13/19 = 0.68
MK2 - 10/17.5 = 0.57

Look MWF is going to be 1-1.5ton lighter both empty & fully loaded with some 105-115kN afterburning.

But it's to be a canarded-delta with TVC (most probably) with much higher ITR... Mark1 IOC does 180° in 6 seconds!
And for a delta that's supposed to bleed energy quickly to lose maneuverability, Tejas pilots keep doing turns like there's no tomorrow.
So I'm gonna hazard a guess & say its aerodynamics maybe already better, let alone MWF.

Please elaborate! Everyone was expecting the deal to be signed at DefExpo after such long negotiations. What happened?

Both Arjun & Tejas Mark1A final orders, as well as LCH FOC are supposed to happen at Defexpo 2020.

Please elaborate! Everyone was expecting the deal to be signed at DefExpo after such long negotiations. What happened?

Nothing... He's just prepping his soul for the worst case scenario.

 

[Bhurki]

happen at Defexpo 2020

Any probable date? .

Any probable date? .

No... Atleast I don't know.

It depends on your flying altitude configuration. On wiki it shows Jaguar having 1902 Km ferry range where as on military wiki figure goes to 3524 Km.

Jaguar also happens to have a lower TWR and less efficient engine. With EFT you can more than surpass Jaguar performance.

Which part of "Maximum range with maximum internal and external fuel without weapon" you don't understand?

You can argue that with your HAL.

Then why is everyone running after supercruise technology?

Supercruise is more about speed. To extent, it is achieved at the cost of range.

Supercruise is more about speed. To extent, it is achieved at the cost of range.

Your 'maximum' range is all about altitude and flight path. Is it Lo - Lo - Lo , Hi - Hi - Lo or is it Hi - Lo - Hi.

https://books.google.co.in/books?id...0QAQ#v=onepage&q=hi lo lo flight path&f=false


Wrong! It is to preserve speed, thus using less fuel, thus increasing the range.

I THINK YOU ARE NOT CONSIDERING GE 414 EPE.

 

[Bhurki]

I THINK YOU ARE NOT CONSIDERING GE 414 EPE.

Ofcourse i'm not..

IT DOESNT EXIST

It was a project that was to be funded by the USN for its F18SH upgrades, but they haven't considered funding it yet.

So unless India is happy to fund GE with a few billion dollars, EPE will not happen.
Right now the engine that HAL has choosen is
'F414 INS6' with a thrust of 98kN.

58 KN dry thrust engine can not support 17.5 MTOW. With Existing GE 414 with 58/98 KN 17.5 KN can not be supported. So it must be 64 KN dry at least.
