Sukhoi PAK FA

[Bahamut]

Whether project is 1st in line or not , money is always a big big problem , smaller cost for each units mean you will be able to afford more of them. The question is do they want fewerT-50 with GaN radar or more T-50 GaAs radar

Most probably it GaN, if Mig 35 can have it it FGA 35 THEN so can PAKFA

 

[Bahamut]

IR + UV actually inferior to staring IIR sensor such as DDM-NG or DAS

Sir can you explain how in technical terms, I was unable to find an explanation.

Right , Mig-35 do not have GaN radar , and FGA35 is nothing more than a prototype at the moment ,no different from the VISTA or MATV program for F-16 .Moreover , apart from some sentences Wikipedia with absolutely no reference , there is no official claim that that FGA35 is a GaN either , even from Phazotron

Zhuk-A has been rejected by VKS in favour of new radar with flat LTCC-packed GaN modules. Apparently this was the reason to not to buy in fact already RTM product.

IR based MAWS
Pro :
- longer range in good weather condition
- can detect missile with burn out motor
Cons :
- rather useless in bad weather
- high false alarm due to sun , flares ..etc
- really bad at low altitude due to ground clutter

UV based MAWS
Pro :
- unaffected by ground clutter
- generally unaffected by weather
Cons :
-useless if missiles motors already burned out
-cant really detect anything that burn less hot than a missiles motors
-really bad from 10 km and higher due to ozone concentration in atmostphere

IIR based MAWS
Pros:
-Very long range
- can detect missiles with burn out motors
- much less false alarm rate compared to IR based
-can operate at low altitude
-can identify kind of targets
-can be used to cue others weapons
Cons:
-Useless in bad weather

favour of new radar with flat LTCC-packed GaN modules.

Which one ?

If I understood you right, IIR sensor is just multi-unit matrix based sensor which is composed from several hundreds of IR sensor units.
Am I right?
If so, that nothing can deny sensor developers to place IR and UV sensing units into a common matrix which allows to utilise both bands advantages and compensate IR sensors disadvantages by UV channel.
And 101-KS is exactly so bispectral matrix-based imaging system which is quite unique for now.

If you put many IR detectors together in an array then basically you would make an imaging infrared sensors
Anyways , the only advantage of UV over IIR sensor is that it work in all weather condition at low altitude , but if you really think about it : if the weather is bad enough that the IIR missiles warning system doesnt work then obviously the IR or IIR or SAL of missiles wont work either, if the missiles is radar guided then that would be the job of radar warning receiver system.
Secondly , modern missiles don even use HTPB-AP-Al as fuel anymore , they use HTPB-AP or GAP instead , and detection range of UV missiles warning system again those kind of motor is just really bad around 300-500 meters ,why would you want a sensor that can only detect a missiles from 300 meters or less , and it only work at altitude lower than 10 km and only if the motor is still burning ?

Well, I believe in common sense and usability considerations in any weapons related decisions. If Russian engineers have done something than it is really useful and gives significant profits. Russians had not spotted doing anything really useless ever being actually very minimalistic and conservative in nature.
So I prefere to wait for 101-KS export sertification to find out the purpose of bispectral matrices in it.

Russian PAK FA Fighters Equipped With Operational Engines To Be Tested In Late 2017

Russia is planning to test its Sukhoi T-50 (PAK FA) fifth-generation fighters using operational engines in late 2017.

Also equipped with advanced avionics and all-digital flight systems, the fighter is set to become the first operational stealth aircraft of the Russian Aerospace Forces.


“PAK FA with operational engine should begin tests in the end of 2017, to begin a series of tests as part of the plane in the fourth quarter,” Alexander Artyukhov the head of the United Engine Corporation was quoted as saying on Thursday by Sputnik News.

"We will complete the trials of the PAK FA fighter jet next year. The first five PAK FA fighter jets have been included in the contract," Russian Aerospace Force Commander-in-Chief Viktor Bondarev said.

Above: Work share breakdown for the developmental fifth generation engine; below: intended applications for same. The Russian language legend shows a common core [Basic Gas Generator] exploited for a range of other applications, including maritime surface combatant power plants, and fixed power station or gas line pumping applications (NPO Saturn & Ausairpower)

Last Friday Tass news agency reported that Russian Air Force would receive the first five T-50 PAK FA fifth-generation fighter aircraft in early 2017. "I believe that we will start receiving the first five planes next year," Bondarev said. The serial production of the advanced fighter jets will begin soon after the initial delivery, he added.

Besides, the Aerospace Force is also receiving Sukhoi Su-35S multi-role fighters, Mil Mi-28N (Havoc) and Kamov Ka-52 (Hokum-B) attack helicopters, as well as upgraded Tupolev Tu-95MS (Bear) and Tu-160 (Blackjack) strategic bombers that "are showing excellent characteristics," the Air Chief said.

Further, about 20 Sukhoi Su-30SM multi-role fighters would be delivered to the Air Force annually. “We will receive 20-24 planes, which is needed to equip an air regiment," Bondarev said.
The contract is being awarded to Irkut Corporation for the supply of 30 Su-30SM multi-role fighters as part of Defence Order for 2016-2018 to the Russian Air Force by the end of 2018.
The PAK FA fighter was first seen in January 2010 when it was presented at the air show MAKS-2011.

Wow... Dude...
Calibr is GTG missile system, how can it have even some similarities with MR SAM?
I'd rather predict Russian aid to update Akash like Russians have updated Buk-M1 to Buk-M1-2 and M2.

Oh sorry What I meant was NIRBHAY
What do you think?
Btw Akash is too much similar to 2K12

 

[Zebra]

Russia developed 2 fighter plane platforms >>>> MIG 1.44 & sukhoi T-50 .

China bought MIG 1.44 and modified it and now it is known as J-20.

India is also Buying Sukhoi T-50 Platform .................and will modify it .

Joint development is not the right word .

why Russia is selling these platforms ?? because they need money .

Sir, that is not my problem................................................

Internal MWBs profile speculation based on insiders info:

And another profile X-Ray - N036 Belka antennas are clearly visible:

And possible 3V55A Onyx (3M55EI BrahMos) attachment:

PAKFA. a F22 child ?

At least the chinese don't paste and copy the J20 .....

Apparently physics is the same for Russian and Americians

Only for blind humanitoid like @BonPlan
T-50 has no commonalities with F-22 except they are both heavy fighters.
T-50 has more commonalities with YF-23 and F-14 if we look at their AD layout.

hummm..... YES ! you're right !

a question : Mig 1.42/1.44 was flying or just a mock up?
