[AMCA]

Is it true, except for Airframe, nothing is indigenous in AMCA?

With over 2000 In house vendor base, do you think this project is gonna be any less indigenous? Engines and Radar do not make an airplane, not even 10% of it.

HAL/ADA has to tackle both challenges ie. engine development and fighter development in parallel. Given the complexity involved in engine development that are powerful enough to power supersonic jet engine, we should de-link it from fighter development which it self is very challenging.

IMHO HAL-ADA should put AMCA with GE/foreign engine on priority instead of going step by step to tejas-MK2 and then to AMCA. The later (or current route) will suck up all resources without leaving space for engine development which will bring HAL-ADA to square one even if AMCA is ready as engine will be still imported.

Instead this is what i propose.

1. Let HAL produce tejas-mk1a in +300 numbers incentivizing the private players to stay invested while encouraging them to upgrade to next gen systems.

2. Abandon the plan to use GE engine for tejas-mk2 and let derivative of kaveri engine power it. any enhancement in tejas-mk1a is not worth redesigning for yet another imported engine.

3. let navy buy imported naval fighter instead of waiting for tejas-mk2 as these numbers are really small. so not enough incentive for diverting hal limited resources for this aircraft.

4. HAL-ADA should speed up AMCA with GE engine and after that may be AMCA-mk2 can be with Indian engine.


this way jet development will not hinder engine development and vice versa.

No such thing. The main imported component of the AMCA will be the engine. The rest is expected to be indigenized. MoD is also working out a plan to wholly indigenize the engine in India. There will most likely be a second engine program for an AMCA class jet.

Engine tech is also changing a lot. Generic turbofans may eventually become obsolete. We will need hybrid engines that combine turbofans, ramjets and scramjets into one single propulsion system. That's the future. The Avatar program is expected to combine turboramjet with scramjet.

Not to talk of Engine, avionics suite, radar, stealth paint...even cockpit seat will be imported. Scramjet is not suitable for Fighter plane which needs to decelerate suddenly.

The engine will be GE, but made in India. The rest will be Indian. NAL is already testing RAS composites.

The ejection seat doesn't have to be indigenized. It can be bought off the shelf. It doesn't affect anything.

Scramjet is not suitable for Fighter plane which needs to decelerate suddenly.

The engines will activate based on what's required of the aircraft. The turbofan will be used for maneuvers in the lower atmosphere while scramjet will be used in the upper atmosphere.

What's the advantages of GaN based radars?

1. GaN gallium nitride based components is suited for military radar application due to high power aplifier (HPAs) in transmit and could be used as limiters and low noise amplifiers (LNAs) in the reciever.

2. Higher radiated power per element increases range, reduces antenna size (area/module count) thus reduces cost per radiated watt lower.

3. Higher voltage operation redures current requirement.

Problem is to maturity, manufacturing and initial cost.

For layman GaN for fixed power level is twice costly than GaA, 1/3 to 1/4 in size, cost per watt 50-60% of GaA.

In short

GaN is future of Aesa period.

But depends on the thinking and the perception of the developer and the user, Some might find Pesa even better than Aesa due to simplicity, and lower cost and less comparative disadvantage and for the Gignos I got Aesa you got Pesa I am better and I got GaN based so I am supreme.

Even if we able to design the stealth airframe while not compromising the aerodynamic performance is itself an achievement worth noting. Rest is just avionics modules that can be replace or upgraded later on.

This approach, my friend, is not right. India has always been weak in fundamentals. If we had a viable grounds up approach, today we wouldn't have to put up with humiliations heaped upon us by foreign companies and Govt. in the form of Technology denials, overpricing, sanctions, withholding supply of spares and what not. Remember, someone who's cardiovascular, kidney, brain and other vitals are not in good health can not compete with poster boys of the town by going for the latest hairdo and attire.

Shows a mix of old and newer designs.

You can assign which is the newer and older design with above diagram, which shows the design progression.

Seems to be one of the early, early design.

When it was labeled, MCA, not AMCA. Looks like a twin engined LCA.

Black bird was used such hybrid engine,Yeas its true that it less manuerabl.
