Russia shows off AESA radar for PAK FA fighter

16:53 28-08-2009


Russia unveiled the first element of its fifth-generation Sukhoi PAK FA/T-50 fighter during the Moscow MAKS air show, with Tikhomirov’s NIIP having exhibited the type’s active electronically scanned array (AESA) radar, Flight International reported.

The newly unveiled unit is intended for integration with Sukhoi’s heavyweight fighter prototype, which air force commander Aleksandr Zelin says is due to fly in November or December. The aircraft was shown to President Vladimir Putin in its assembly phase during his May visit to the KnAAPO production plant in Komsomolsk-on-Amur.

Tikhomirov says the AESA antenna entered benchtesting in November 2008, and was mated with the radar’s other blocks for an initial integration test "this summer". A second example to be produced for an operational prototype of the T-50 will be completed by mid-2010, it adds.
NIIP has not provided any details about the new radar, beyond saying that its antenna contains more than 1,000 solid transmit/receive modules. The design is Russia’s second AESA system, following the Phazotron Zhuk-AE being developed for the RSK MiG-35.

Outwardly, the T-50 is believed to resemble the configuration of the US Air Force’s Lockheed Martin F-22, and will share design features such as internally carried weapons and supercruise performance. The Russian aircraft will also have an integrated on-board sensor and flight control system which will include several radar antennas to provide a 360° coverage.

Sukhoi will complete five prototypes for initial testing, including two to be dedicated for ground test activities. Initial trials are scheduled for completion in 2011-12, with the company expecting to produce an initial batch of aircraft for operational trials by 2015.

Russia’s initial batch of aircraft will be powered by NPO Saturn Item 117 engines, derived from the supplier’s AL-31F series. A new engine will be incorporated with later production examples, with this likely to be a design proposed by MMPP Salut and based on the AL-31FM3.

India is also seeking its own version of the T-50 under an agreement with Moscow. This is expected to feature some airframe differences and use Indian avionics equipment. MILAZ

Maybe... the order has to be big enough to forgive past transgressions.

Time will tell. I have no doubt they will develop one on their own in a decade.

It will be a dark blue field on the edge. OLS would have to be pretty damned good to see a discharge no more than a few centimetres wide.

Excellent. I wouldn't have picked a better colour. Would not look intimidating, regardless blue colour disperses best in the atmosphere compared to red or green.

An OLS is the only obvious counter to Plasma stealth. Or the enemy just have to hope there is always a lightning hitting the PAKFA every few minutes for the Plasma to disperse.

There is a small problem with Plasma stealth...it ends up screwing the radar of the fighter itself. The Russians are in their third gen plasma generator but it lacks adequate power.

Lack of power is the reason Plasma will be used on certain surfaces.

And how are they planning to stop the plasma interference with their radar?

The fighter will utilize the smart skin concept. With this the radar can be placed anywhere on the plane. Wings, tail etc. They will perhaps leave "gaps" for the radar...just guessing. Also may use active ECM equipment similar to Rafale's SPECTRA.

 

[SATISH]

The spectra uses active cancellation for stealth...the Plasma stealth is a very complicated thing the smart sensors concept is still in its infancy. and plasma interferes with all of them. that is what the russians opted for conventional stealth over plasma this time.

well first ...when you are in stealth mode ..and u switch on your onboard radar ....your stealth is no more...B-2 spirit bomber used to even maintain radio silence ...the bombs were dilivered by laser targetting and using JDMAS...is u see plasma generator has to be used only to get close enough to the enemy and the stealth can be forgotten and missile can be fired ...and yes it dose negate the onboard radar ...but plasma generator does not need to be switiched on all the time

take this hypothetical situation ....US carrier battlegroup is in the blatic sea ...russian tu 160 long range bomber take off with full payoad head towards the US carrier battlegroup ...switich on the plasma generator...come with 100km of carrier task force and diliver the payload ....so since tu 160 is very close ...us carrier battlegroup gets very little reaction time ....

Active Electronically Scanned Array - Wikipedia, the free encyclopedia

For that only these Radars are used....nothing beats the onboard Radar in an aircraft. It is the one guiding the weapon system used by the aircraft. Not the AWAC

I will not doubt what you said. Until its actually out, we cannot be sure. We are also not sure what the Russians may opt for.

Anyways, SPECTRA does not use Active Cancellation as of now. SPECTRA only uses active emitters rather than passive emitters used worldwide.

This is correct in regards to the plasma wing as well. It would only be needed for high speed or hard angle maneuvering as that required in kombat. I also believe it would help hide a weapons bay launch.

hi

when these planes come to India and what is the role by our side

pls tell me

The Planes will arrive in the 2020 Airframe and will be fully operational by 2025.
The HAL will be making crucial components and ADA will help in the design of the twin seater version and develop the software for the MC.
And the GoI is paying $10 billion for the development.
We will also be helping the Russians in developing the smart skin on composites for the aircraft.

thanks for the correction mate...was in a hurry....

wel let hope for the best that aircraft arrives in 2020 not that i think there will be any delay or anything , just that IAF needs aircraft fast , and plus the PAK FAGA will be better than the Raptor , should be named "Raptorisiki " or raptor killer

 

[Tamil]

Raptor ????

wel let hope for the best that aircraft arrives in 2020 not that i think there will be any delay or anything , just that IAF needs aircraft fast , and plus the PAK FAGA will be better than the Raptor , should be named "Raptorisiki " or raptor killer

ya its true

As far as Raptor is concern it is very venerability, that's the only reason USAF is not able induct it. i watched in NGC a program called future Weapons that 1 flight hour of F/A - 22 RAPTOR need (+/-) 25 hours of maintenance. even a 7.62 mm bullet hit in the flight will down the whole AC. thats while they are not tested in Iraq and Afghanistan.

That's while they are thing to speed up the F/A-35 JSF productions.

Note: may be it is true or not the pure credit goes to FUTURE WEAPONS in NGC.

 

[AJSINGH]

if PAK FAGA feature some kind of plasma stealth , that would be out of the world , Russian domination in combat avaition will be back

hi

as sukhoi offer su35 plane to india we can select at least 30 plane su35 or su47 which plane will be the best as we have su30 that are alos good planes we have

su 35 is 4-5% more advance then su 30 we can select su 35 or su 47 planes

how you guys things

jai hind

 

[tarunraju]

Su47 is not for sale. It's a technology demonstrator which will probably never make it for mass-production.
