AMCA - Advanced Medium Combat Aircraft (HAL)

[Adrian Corvus]

Finally!! the larger model with the camo looked...weird...

 

[FalconSlayers]

It was a sleek and sexy design, now it is fatass like F-35.

defence decode guy is saying its not irst it is eots

He has no source.. Probably took it from DFI or secretprojects. I posted it in both places.

what?

Ok I need to explain how Whitcombs area-ruling works (for those who don't), so that all you fuckers can properly understand the point of the fatassery... Tag anyone who has the same trouble.

In simplest words this is an ideal curve, that the area of cross-section of the jet should plot on a graph, along the whole length of the jet (marked in black). That's the only thing that dictates its shaping... otherwise you can shape it like yo-mom if you want, doesn't matter as long as its shape follow the rule.
But that can't be achieved in practice & the actual curve usually deviates as depicted.

Now, you will note that after the front tends to remain pinched, middle becomes excessively large & the end tends to drop abruptly.

So this is how the shape modifications tend to work.. They increase the cross-sectional are where needed (canop bulge & elongated tail), while reducing it where needed (famous coke-bottle shape in the middle at wings).
This way you try to achieve as close to the ideal area-graph as possible.

So whole detrimental to stealth characteristics, this old sleek AMCA cannot match the performance of the new, fat AMCA due to much higher drag it faces from inferior area-ruling.

Nice design!

 

[fire starter]

Very nice article about tejas real time control system which comprises of three systems.
1. Flight control.
2. Brake, hydraulic and engine control.
3. Environment and fuel control.

These all systems are highly integrated but are independent of each other. In AMCA it will be further upgraded to be known as active control gear system by using artificial neural networks.

I don’t care fat or not !!
Stealthy enough or not !!
just want to see it flying asap...
ADA,DRDO,HAL or wtever please don’t keep us waiting!

save all your enhancements and improvements in design and performance for mk2!
its more than enough for me...

MOD a$$h*l£ fund it already!!🥲

Interestingly the top side of the AMCA's latest model from behind the cockpit onwards is very Su-57ish. Especially how the engine tunnels diverge.

can someone here explain the benefits of adaptive cycle engines(operational advntages)

Less fuel consumption ,higher efficiency , variables thrust with good efficiency

 

[SARTHAK]

any infrared signature reduction advantages??????

 

[Lonewolf]

any infrared signature reduction advantages??????

Obviously ,in cruise mode

 

[SARTHAK]

Obviously ,in cruise mode

no i was asking whether on the same super cruise speed (say mach1.4) on normal engines vs adaptive cycle engines will there be any advantages for the latter?

Yeah somewhat , as they will have the third cycle where extra air can be added to improve efficiency and cool at the same time so ir will surely go down , I don't know whether it will have afterburner or not , itay eliminate afterburner , but that part I am not aware of much

wow no afterburner, if true than it would be huge advantage

 

[Lonewolf]

I mean I don't know about it ,most of research was done on f 135 and f136 core , so don't know about afterburner

Transonic acceleration will be way better compared normal engines!
ACE is like DCT in sport’s cars!

Pixellated camo, which members here call ugly.
