GaN uses lesser power than GaA1500 +for du 30 mki can be done , only thing that hinder is power

Bhai, a bit premature to claim it....engine apart?What fighter jet requires less maintenance?
Answer (1 of 5): The HAL Tejas requires the lowest maintenance among any 4/4.5th generation fighter in operation today. The Tejas uses majorly carbon composites over metal in its making. It has the highest usage of composites of any fighter jet in the world. The composite materials constitute 45...www.quora.com
GaN devices can operate at higher temperatures and higher voltages than either GaAs or silicon so they can deliver higher power. GaN can operate at five times higher voltage and twice the current of GaAs devices, have higher potential power-added efficiency than GaAs above 10 GHz and silicon above 1 GHz.GaN uses lesser power than GaA
AL-31 are powerful enough to provide necessary power to 1500+ Uttam AESA. Primary concern is power dissipation and how will this heat be extracted from the radar. As of today we do lack is thermal dissipation domain. Even for our DRDO/DARE SPJ we imported thermal dissipation solution from Israel.1500 +for du 30 mki can be done , only thing that hinder is power
All that came from the stupid fetish of being the smallest fighter mindset. They were coming from the Gnat/Ajeet mindset. Too bad we couldn't make a clean sheet redesign in the 2000s.Yes that's true... That's where experience in designing craft come into play. If you look inHey guys aerodynamics and air intake designs are very important. Gripen super cruises inspite of being havier than Tejas.
The mk2 will definitely improves on that but then there is always a limit.
The GE F414 won't provide the thrust required to do so .
Contrary to some common belief it’s actually more challenging to make something capable and light as you run into issues with packaging and miniaturisation quite quickly, listen to the blue sky podcast with J. malonker, he touches on this topic and says this restraint spelt out in the original IAF ASQRs created huge technical challenges. All because they wanted to be cheap and short termist to get the LCA to fit the MIG-21’s HASAll that came from the stupid fetish of being the smallest fighter mindset.

IAF started out asking for a simple MIG-21 interceptor replacement. Over the years they kept adding requirementsA two engine version would have been ideal way to go like Rafale.
But i believe inexperience in designing or producing them and cost to operate etc all played in the mind of IAF HAL and ADA.
With Jaguar though we saw how a two engine fighter could be low maintenance and cheap to operate too.
We should have worked up from HAL Marut HF 24.
What's lost is lost though hopefully mk2 and Amca turn out on time.

No way is LCA MK.1 what ADA would design with a clean sheet if current ASQRs were given to them in 1990
How many more Marut would have been built if India had taken up the RR offer to make a higher thrust engine for - in today's terms - a pittance? A longer production run might have kept a team of engineers together longer and a bank of engineering expertise alive to give Tejas a better start.A two engine version would have been ideal way to go like Rafale.

GaN radars have lesser power consumption compared to GaAs radars, and ability to operate at higher volatage levels. This translates to more radiative power output; if both radars are fed the same electrical power input.GaN devices can operate at higher temperatures and higher voltages than either GaAs or silicon so they can deliver higher power. GaN can operate at five times higher voltage and twice the current of GaAs devices, have higher potential power-added efficiency than GaAs above 10 GHz and silicon above 1 GHz.
From where you can to conclusion that GaN uses lesser power than GaAs?
Lets analyze the statement.GaN radars have lesser power consumption compared to GaAs radars, and ability to operate at higher volatage levels. This translates to more radiative power output; if both radars are fed the same electrical power input.
Higher voltage also means current drawn will be more in same amount of time.GaN radars have lesser power consumption compared to GaAs radars, and ability to operate at higher volatage levels. This translates to more radiative power output; if both radars are fed the same electrical power input.
Super Flanker only saying what IAF once said during that time. Its not about interceptor but spy plane.Well Mig 31 is essentially an improvement overthe Mig 25 so as you have requoted satellite made the reconnaissance part useless.
Other advantage was speed where Mig 31 only excels to intercept big radar etc.
Well Sukhoi provided more... Big radar can intercept with long range missiles and unlike mig 25/31 can dog fight and provide air superiority.
So Sukhoi essentially ended the need of Mig25/31 other advantage too.
Regarding maintenance if we really needed it we would have maintained it somehow or bought mig 31. But with Sukhoi and satellites etc there wasn't much need.
For Russia having such a very large territory it might be meaningful to still have them.
Can you please elaborate your point.Super Flanker only saying what IAF once said during that time. Its not about interceptor but spy plane.
