AMCA - Advanced Medium Combat Aircraft (HAL)

[Dark Sorrow]

I didn’t find any such but heard that soldiers wear Pixelated camo because it has less visibility in IR Spectrum.

IR sensors work by approximating ambient heat source relative against pre-calibrated heat source. Pixelated camouflage won't help in this regard.
In IR Spectrum you just monitor IR emission and compare against pre-calibrated heat source to generate an image. Camouflage doesn't help unless it regulates IR emission or absorption.

From the 2009 RR press release it appears that they designed an adaptive cycle engine and GE subsequently completed the design and built the engine. That took about a decade, it seems. I guess RR would take many years to do the same if GOI and DRDO chose to develop an adaptive cycle engine. I'm not too sure how much of a contribution DRDO would be able to make in developing such an engine. The cost might be alarming, too: 15-30 times what was spend on Kaveri development?

we have 7-8years as from now hope that be enough for a yf120 type engine with comparatively lesser thrust intended! I don’t see mk2 happening before 2032.
we can’t really compare kaveri cost with it as it was a 4gen and still incomplete project and even for it govt is always criticised for providing too little fund!
&
even if cost 15-20times of it i think it’s worth it !
it is a matter national security, engine is the heart of any platform without it platform is useless, this was the very reason hf24 Marut failed!

IIR missile track heat exhaust from the engine. How will pixelated camouflage breaks the lock of the IIR missile seeker! If it was so easy no countries would be using flares but only pixelated camouflage and IIR missiles would be obsolete.

Ask Dr AK Ghosh. He mentioned it in the interview. IIR also captures an image of the plane up ahead to not be deceived by flares. If you have a sufficiently pixellated image (whose pixel values will be normalised during processing), then it gets difficult to keep track of it against the background because the SNR becomes low. At least that's what you will learn in object tracking problems in computer vision. But experts know better if anyone can please answer.

Software Reconfigurable State-of-the-art Communication Suite
for Fighter Aircraft.

The conventional communication systems
available consist of individual systems for each functionality.
In such cases, the failure of one system leads to failure of the
functionality of that system and the mission has to be
completed without that system. Hence there is an urge to
develop a state-of-the-art on-flight software reconfigurable
communication system to provide better redundancy,

I was informed that Image Segmentation technique (precisely Instance segmentation) is used to tract the hot exhaust from a jet and differentiate it (engine exhaust) from a flare.

Looking for it. I am absolutely certain of this one. Dr. Ghosh mentioned it in one of his AI2021 interviews.

Neural net based instance segmentation techniques is one of the latest techniques in IIR seekers to differentiate flare from exhaust. I'm not aware of any missile that uses this technology yet that is in service. Ones on the market still use old fashioned image processing and KNN based techniques based on contrast ratio of target vs background. But I could be wrong on this.

Final Design Configuration of AMCA emerges
In 2015 we almost had AMCA design frozen, & vwe were seeing only minor finalisation tweaks.

But then in 2019 suddenly a drastic change was brought in (like MWF vis-a-vis LCA Mark2) & the design changed drastically. Every single one of those were aerodynamic refinements, so I reckon it was an user feedback that caused it.

Enlarged wings, reshaped fuselage top, redesigned & repositioned stabilisers (engines further apart, could get in here)...

Now just waiting for it to get the 110kN TVC engines & 1:50

1:50 ??????

 

[Ar.gaurav28]

DRDO is the ray of hope in Indian defence sector

1:50 ??????

It's a hotlink.

DRDO is the ray of hope in Indian defence sector

Oh! fuck yeah..

 

[FalconSlayers]

DRDO is the ray of hope in Indian defence sector

Will be in MK2 AMCA beyond 2034.

 

[Ar.gaurav28]

Will be in MK2 AMCA beyond 2034.

I don’t think any fighter being inducted before 2035 possessing such weapons!
biggest hurdle in mind is for it we desperately need RR engine(tempest) !!
FCAS engine will involve Germany so forget about IPR...

Is it true?

It's all right lmao.

It's a good thing right?.. That people are coming to DFI for knowledge on this stuff. That's a great progress.

Even a few years ago when I joined this was just a right wing nutjob echo chamber.

From DFI I have learned a lot,happy to share few things too.
