AMCA - Advanced Medium Combat Aircraft

[Bleh]

We are doing exactly that, stealth airframe +tejas mk2 tech.

and by doing that the timeline for first flight planned for 2028.

The problem is not avionics tech.
But the airframe itself.
We are going solid single peace bulk head, for that we meed 50k+ton forging press.
So we are currently creating that press.
After which that press will create the bulkhead.

Not quite I'd say.

Even if MWF is 4 times stealthier than LCA it's still a 4th gen that'll carry things externally.
While we're aspiring something that'll need us to induct several dozen jets every year. Continue within on the bulkhead but while we're at it "downgrade" the AMCA concept & make a prototype in similar manner to MWF & roll it out alongside MWF in FY26 only.
Start induction ASAP..

They'd claimed that mock-up is an actual jet, no?. Fit in two F414s & get it airbourne. Sure it'll use IRST instead of EOTS, but still be a stealthy fighter with IWB & probably better than all IAF jets at 2030. Definitely better option than Su-57.


Actual AMCA can follow when it does.

Were doing exactly that for the initial testing of "prototypes", and doing that timeline is 2028 for first flight.
Why do think testing period is 8-9?


The mock up is not an actual jet, it's an enegeering model.
Meaning internally it's designed in a way actual fighter jet will be designed it has ducts, space of engine, radar, cockpit, landing gear, space for electronics etc.
A simple mockup just looks like a jet externally.
With that Said, it's material is nowhere the quality and standard for it to ever fly, unlike what alpha defense said.
Even the wings and tails are maid up to soft bendable materials.
Basically a mockup but with both external and internal layout like an actual jet.

Why do Indian airplane designers consistently go for smaller air intakes when you know that you need more air intake to get more power?

Interesting observation.

Do other OEM's design intakes with allowance for a greater mass of air intake in future enhancements of the aircraft?

Continuing the chain of posts for weapons in AMCA's IWB which is officially quoted 4.2m X 2.2m,
After observing the designs of all BVR-AAMs made globally, and intention of F-35 & J-35 to increase their IWB capacity to 6 AAMs, I had shown by diagrams that only 4 big-fin Astr-1/2 AAMs can fit in IWB but,
6 staggered Astr-2 short-fin AAMs (like AIM-120-D in F-22),
or 6 modified Astr-3 SFDR,
or 8 folding-fin Astr-2 AAMs can fit in (like Chinese PL-15).

I took the CAD of Astr-2 big-fin by artist "Akela freedom" & edited in Paint to match short-fin version made by artist "Kuntal Biswas" which is also identical to AIM-120-D. So the forward fixed fin has been shortened & shifted forward & rear fin leading edge more swept back, that's all, simple quick edit.

Now we can see the comparison more clear & precise, 4 & 6 big-fin AAMs vs 6 short-fin AAMs in the outine of official dimension of IWB. Unfortunately an updated CAD is not released yet by any artist or DoD.

I did this few weeks back but I waited for Aero-India, hoping they would officially increase the IWB capacity & showcase, but didn't happen. But this is not an up-hill task & can be done easily till IOC jet.

There is no separator wall in the IWB. 1 door panel slightly overlaps on the panel of other side door, means both doors have to open full to drop any weapon, exposing full IWB.
I hope this gets corrected in IOC jet.

So far we have seen multiple CADs & static models with slight differences.
Neither ADA nor the 3D artists release basic schematic diagrams, cross sections, configurations, etc. The ones available so far are low resolution & inadequate.



It is difficult to confirm how the inducted jet will look like & its capabilities.
So taking the most convincing CAD front view & superimposing the IWB dimension of 2.2m width & 0.75m depth, along with BVR-AAMs from TEDBF CAD, it seems 6x Astr-2 short-fin version with 178mm body diameter would fit in IWB easily with or w/o staggering.
SWB is also possible.
With 1.5 ton IWB capacity, 6x BVR-AAMs + 2 CCMs = 6x154 + 2x88 = 1,100 Kg, 1.1/(12+6.5+1.1)=5.6% of STOW.
Wet T/STOW ratio = 2x98 KN / 9.8 / (12+6.5+1.1) = 1.02
With 50% fuel used & firing 4 BVR-AAMs, with 2 CCMs & 2 BVR-AAMs left, wet TWR = 2x98 KN / 9.8 / {12+3.25+(4x154 + 2x88)/1000} = 1.24
