LCA TEJAS MK1 & MK1A: News and Discussion

[Lonewolf]

NATO???

Nah typhoon radar us not integrated fully yet

 

[Lonewolf]

No aircraft yet except grippen . Swedden not part of nato . That does nt mean countries does nt have gan tech like india . So far no plan to replace f35 radar as far as i know .

It already had been replaced , in selective fighter for testing , module are about some 2000

Replaced with gan based aesa radar ?

 

[Lonewolf]

Replaced with gan based aesa radar ?

Yeah , ask @FalconSlayers

 

[FalconSlayers]

Meanwhile DRDO’s AURA project renders are completely ignored.

u can't update engines thrust. I havn't seen what HVT said but plans are ever evolving. I am just saying higher thrust engine would help. Can we get it, what are logistics thats point of discussion.

Yes thrust can be increased but could require help from russians.
U plan according to ur budget and budget doesn't allow a new type of engine.(look at jags)

Don't get confused with engine upgrade iterations with incremental thrust improvement. Those are not slight modification. Secondly those need R&D. This is exctly issue with M88 v4 that can replace F414. We need to invest significantly. Instead of paying R&D and then engine upgrade cost with lesser flying hours u should better go for AL 41s then.

what are u on about?...are u saying upgrading existing engines will cost more than getting new engines?Hal is already woking with drdo to slowly improve existing engines. Do keep in mind we have already paid good money for al31 TOT + all the required infra and getting new engines will mean most of that will go to waste.
As i said before su30 wont get new engines...everything is against it.
this isnt the best thread to discuss this if u want lets take it to some engine thread

Al 41 is just an improved version with a new name so that they can charge more money for license fees.

Why pay for AL 41 then better wait for the new su 57 engine IZ 30 derivative.

IZ 30 have 100+ kn dry thrust and will be suitable for next 25-30 yrs demand.

Perfect idea... only issue is its not developed yet. Al 41 is developed. Al 41 to AL 31 is what M88 v2 3 and 4 to v1.

Wrong It is under testing with Su 57.

VIDEO: Russia flies first Su-57 fitted with new Product 30 engine

Russia's latest fighter aircraft flew on 5 December for the first time with the NPO Saturn "Product 30" engine, which will be the production standard for the Sukhoi Su-57.

and Paying for AL 41 doesn't make sense for now and then pay again later.

Said to go in production by 2025 as corrected engine from 1st set to be put by 2022 end for test. Thats in development for u it can be said to be in production itself. Can't argue. 2025 if they stick to timeline. And 2025 engine untested what u want to go with.

Russia: The first Su-57s with a second stage engine will be assembled in 2022.

The first fifth-generation Su-57 fighters equipped with the second-stage turbofan engine will be assembled in 2022," said Sergei Chemezov, Rostec's managing director. Russia is currently conducting flight tests of this engine, which should enable the Su-57 to achieve supercruise capability.

If u want 2030 to start upgrade power to u. That if they can mature engine and start producing engine in bulk for 200 MKIs. AL41 is here and matured. Next is atleast 5-7 years and thats being highly optimistic.

Good dodge man

 

[Flying Dagger]

IAF is smart enough to dodge such stupid proposal I don't have to do anything but chill abt it.

If u would have read before posting. We were discussing the same. To be with AL 31s itself. I thought AL 41s are better but can be ignored if not that important. Not sure from where u get the idea that we were pushing for AL 41.

i have one doubt about following...

why cannot we replace Tejas's single engine with 2 X Indegenous engines (i.e Kaveri Dry) development of which is in good shape

current Tejas engine= 1 × GE 404F2/J-IN20 turbofan, 53.9 kN (12,100 lbf) thrust dry, 90 kN (20,200 lbf) with afterburner
1 X Kaveri dry= 11,700 lbf (52 kN) thrust each dry *[idrw]*

*https://idrw.org/kaveri-dry-engine-prototype-to-be-showcased-at-ai2021/*


consider following example from USAF

F-5 tiger used 2 × General Electric J85-GE-21 afterburning turbojet engines, 3,500 lbf (16 kN) thrust each dry, 5,000 lbf (22 kN) with afterburner

F-20 tigershark used 1 × General Electric F404-GE-100 afterburning turbofan engine, 11,000 lbf (49 kN) thrust dry, 17,700 lbf (79 kN) with afterburner

F-5 tiger use 2x J85-GE-21 AFTERBURNING engine and F-20 use 1x F404-GE-100 AFERBURNING engine. But if we use the Dry thrust variant of Kaveri, it would not be a AFTERBURNING engine anymore.

Because the airframe shape will not allow 2 dry Kaveris inside of it. Modifying the airframe will become huge work to fit 2 dry Kaveris. And 2 Dry Kaveris in total will give about ~100KN of thrust. That with the added weight will make the plane a very expensive and large brick.

May be its possible to use modified Afterburner version of HTFE-25 with 30 KN dry thrust and 45KN wet thrust
