Had India been a partner instead of Indonesia, it would already have an AMCA for a paltry sum of $1B and 5-10 years earlier than the domestic project.

And look at all those nuts and bolts

 

[THESIS THORON]

WHAT ARE THESE ??

And look at all those nuts and bolts

Better than on a sheet of paper.

There's likely another layer of material that's to go on it, or maybe the bolts themselves have been treated.

Not just that, it is also only the first 'test' article, and achieving final details isn't on the mind.

Here's bolts on a 'combat coded' (as opposed to test, train, attrition units which may not have all the skin treatments) F22.

First of all , first flight of kfx fifth gen is in 2025 so no need of all this .

Better than on a sheet of paper.

KFX is a 4.5 Gen fighter built with extensive hand holding from US Defence contractors. A 5th Gen fighter is more than just a fighter looking like F22. Powerful AESA, Non-protruding sensor faces for all sensors, EOTS, 360 degree passive MAWS, 360 degree Distributed aperture system to extend EOTS ability to all sides of aircraft, DIRCOM, Fuselage integrated Early warning receivers, DSI intakes with design that doesn't directly expose engine intake blades, Radar Absorbent Coatings, Exterior design of fuselage that bouces and scatters incoming Radar waves away from the incoming direction, Internal weapons bay and they need to open, eject payload and close within a very short time to limit sudden spike in RCS and the aerodynamic issues of such a sudden protrusion of weapons bay on the airflow, and many many things more. Oops No. South Korea suddenly built a 5th Gen fighter.!!!

Again, at least its something. Atleast, its a dual F414 powered semi stealth A-A fighter.
India barely has its Mk1a into service.

KFX programme cost is 7.5B for development purposes only. And Indonesia still hasn't paid even the initial installment for its 20% dev cost sharing which is around 1.4B and they are still sending engineers to KAI for training and dev. Indonesia has thrice missed the date for initial payment of some 500m dollars. And Indonesia mostly will get is manufacturing some basic components and ToT for manufacture.

Not that it matters, but if India had to be an partner, what would it gain? Who would be the lead? ADA or KAI? LM is their leading design consultant and most of the components will be of American origin. That will be in stark contrast to what our GoI would wish.
Korea is a good country, but with regards to fighters it doesn't have the research expertise of India. As of now they take heavy American help. But they are learning fast. If India don't catch up, Korea will beat India on that count too.

i very much like the philosphy of this aircraft ,it seems a little more ahead of 4.5 gen aircrafts (more like a 5th gen minus aircraft) ,first it will surely have a stealth advantage over other 4.5 gen aircrafts because of lack of canards , semi recessed bays, 360 ir coverage (like eodas) ,indian analogue can be tedbf
BTW does engine nozzle have serrated edges?

does engine nozzle have serrated edges?

 

[THESIS THORON]

does engine nozzle have serrated edges?

no, those are normal nozzles, they might upgrade that on blk-2.

it is not better than rafale, just it has stealth shaping.

and in ew, rafale will outperform this.

 

[SARTHAK]

no, those are normal nozzles, they might upgrade that on blk-2.

it is not better than rafale, just it has stealth shaping.

serrated nozzle are a part of engine or extension added to the conventional nozzle,sorry for noob question

they are not added to conventional nozzle. it is part of engine

see the zig-zag pattern, that shape of nozzle is serrated. It helps in decreasing the reflection of radar waves (rcs)

so that means we can't modify ge 414 to have serrated nozzle on tejas mk2

just like Russians refined su57 from prototype to production variant

nope, f414 is not our engine, only ge has right to do this.

can it be done ,if we request? although they would charge huge some of money

tejas is not a stealth jet, it only has ram coating, changing from nrml nozzle to serrated one will not reduce rcs considerably.

tejas is rumored around 0.5 msq.

and it is impressive,

it has lowest in all 4.5 jets

 

[SARTHAK]

Does ge f414 has cooling channels for combustion chambers same as m88 has? https://www.flightglobal.com/snecma-m88/26559.article

yes ,its not stealthy but why loose on any feasible possibility of reducing rcs,but i think cost ge will ask will not be feasible
