Data point:


GE's Pearson at AI 17.

https://youtu.be/cMz7QdNK75c?t=4490

Mentions and shows a slide on GE F414 for AMCA.

As I had speculated GE Bangaluru design division, the Welch Center, is spear heading this effort to uprate the F414 by 10%. This arrangement should meet the DTTI requirements. Pearson, in his talk, does mention DTTI.

Found a slide from 2015, showing some of the stealth aspects of the AMCA under consideration (then?):

Infra red signature.
Heat shields around the engines?
Are they going to mix cold air with the exhaust? or an outer layer of cold air from the engine all around the exhaust like in the F-22?
I suppose the air intake and leading edges also heat up some

An article from 2012, that provides some insight about stealth expectations in Indian crafts.

6th gen has barely been defined. Although it will incorporate the manned/unmanned concept.

6th Generation Fighters are already taking shape

In what way?

It still sounds very vague like the FGFA "smoke & mirrors" project.

I have not seen nor read any overall plan for the AMCA. Just some vague concepts of stealth, high speed on-board data buses, some vague ramblings about sensors..etc.

What part of the above cannot already be incorporated onto the LCA MK2? And what real advantage does it offer?

There has been no information on the AMCA's design released and no public discussion about what really this so called 5th gen plane design will offer. Some small group of individuals seem to have decided on what it should be without consulting stake holders.

Its not a good sign. I predict the AMCA project will end in chaos as mid way through they discover it offers nothing evolutionary let alone revolutionary as an aircraft.

After reading that terrible plan to make the LCA an unmanned fighter where little thought other than making the aircraft fly way points and drop its load has been given, the AMCA plan (more like lack of it) looks suspect.

Have a debate on the design of this plane BEFORE rushing ahead and making bad decisions.

Have been running into a bunch of old AWST articles on the AMCA. Posting some xtracts to provide some continuity (hopefully).

New Design For India's Advanced Medium Combat Aircraft

Feb 11, 2013.



India has unveiled an updated design for its fifth-generation fighter concept, known as the Advanced Medium Combat Aircraft (AMCA).

Representations of the fighter have changed often in the last few years. But the scale 1:8 model of the concept displayed at last week’s Aero India 2013 show in Bengaluru is understood to be the final airframe and platform with which the program will proceed.

The twin-engine, stealthy, multirole fighter was first unveiled at the Aero India show in 2009, in the form of a metallic wind-tunnel model. At the show in 2011, a reshaped model saw its designers give it an F-22-like sensibility.

The final design, or at least the one the concept designers have put out this year, is strongly reminiscent of the Northrop Grumman YF-23 experimental fighter prototype that lost to the Lockheed-Martin led F-22 Raptor program in 1991.




A senior scientist at the AMCA directorate in Bengaluru says, “We have the fourth-generation Tejas on the one hand. But evolutionary technologies we are developing for the AMCA are on the cutting edge. They hope to be comparable with the best in the world. If we need a little help along the way in the interests of pragmatism, cost and time, we will study the feasibility of cooperation. But this ideally needs to be a fully Indian program. Sensitive stealth technologies will not be shared by foreign technology companies.”

A brief list of the ambitious technologies that India’s Aeronautical Development Agency (ADA) hopes to equip the AMCA with includes a panoramic active matrix cockpit, triplex fly-by-light electro-optic architecture, serpentine air intakes to suppress radar signature and an optic-fiber-based digital flight control computer.

Describing the AMCA as a “fifth-generation-plus” platform, DRDO chief Vijay Saraswat recently said, “Work on the AMCA will begin soon. This will involve identifying technologies and systems for the aircraft.”

I was under impression that to achieve all aspect stealth the antennae were supposed to be conformal but this pic tells otherwise. IIRC khan went great lengths to have an effective conformal antennae and sensors to not compromise on stealth.

Weren't they working on conformal antennas for AMCA..?? Saw something in AI2017. From the ADA AR 2016:
Development of V/UHF Conformal Antenna for LCA MK2 done.
Under Ghatak program, mention of Conformal Antenna development work.

Yeah they're working on conformal antennae.

From some video I think. I remember seeing it somewhere, most likely a video at ada/drdo stalls.
