Again, nobody mentioned it, but look at the vertical surfaces new RWR aerials.

TsKBA have not developed a fully new RWR since 1982 Pastel (L-150), but those aerials look very different to those from Pastel onboard other Flanker (like Su-30MK2)

Maybe L175M Khibiny-M suite introduces a new RWR?

Old news, nice details

Transitional role: Sukhoi plans T-10BM fighter’s two-track production strategy

Aerodynamic characteristics have been improved and the control surfaces are smaller than those of the Su-27. In order to increase airframe service life, many aluminium components will be replaced by titanium equivalents.

Quote:
The amplifier of Irbis’ radar transmitter has been developed from the N011M radar that preceded Bars. The processing system of Irbis is new, comprising two Russian computers – Solo-35.01 (initial signal processing) and Solo-35.02 (data processing and radar control). Other Russian radars use older computers from the Baget series, whereas the Bars radar uses Indian RC1 and RC2 computers. Irbis software employs elements from Bars (Su-30MKI) as well as from N001V (Su-27SM) and N001VEP (Su-30MK2) radars.

Quote:
Apart from typical targets such as aircraft, helicopters and cruise missiles, Irbis is also intended to be able to detect and engage future hypersonic flying vehicles, air-to-air (AAM) and surface-to-air missiles (SAM) threatening the aircraft, as well as short- and medium-range ballistic missiles.

Quote:
New capabilities include automatic identification of the target by class (large, medium or small; helicopter or cruise missile, etc), as well as air-target identification by type against a comparison made with up to 20 flying vehicles held in the system’s library

Pit’s note: NIIP has said that these capabilities will be further researched and will be implemented in a series of further Marks (Mk) like the RLSU-30MKI Bars was developed (N-011M Mk1/Mk2/Mk3)

Quote:
An experimental version of the Irbis with a temporary Pero antenna began airborne trials on 24 June 2005 on the Su-30MK2 fighter plane. The tests confirmed search ranges as well as the possibility of the simultaneous handling of nine targets – two real and seven simulated. The radar worked in air-to-air and air-to-surface modes simultaneously. As of September 2006, NIIP had made two more Irbis radars – the first of which is to be tested in the air on Su-30MK2 (side number 503) in late 2006.

The Russian press has revealed that a plasma screen proposed by the Institute of Theoretical and Applied Electrodynamics (ITPE) would be used to reduce the cross-section of the radar’s antenna. It has already been tested on the N011M radar of the T-10M fighter.

Thanks Jack!;)

Thanks Scorp and TMor…no problem, I know myself is difficult to find nice data on French kit, 😉

Was RBE-2’s “low” detection range justified at design level by the use of LPI oriented specs that compromised the design?…that would make pretty sense to me, have read (don’t know how much accurate) that RBE-2 was touted as an LPI radar (or something with LPI characteristics)

Interestingly, RBE-2 uses four receiver channels, instead of the typical three used on most phase-comparation monopulse radar. One receiver channel should be dedicated to ECM tracking like on Captor-M (also quoted with this kind of feature)

Irbis-E per example is also quoted as four-channel receiver.

Thanks RSM-55, you’re always kind with the quick answers 🙂

Let me try some other ones:

a) Wich area of radio-electronic industry did you think Russia is falling behind?, my opinion is mostly on EW systems (being passive ESM/RWR gizmos, most acute case, compare it with the very rich and fluid european and american markets with lots of companys and products in the area), but radio-comunications for aircraft is something I have never heard that much..looks as something not important, but is there anything in Russia right now at service, compared per example to Have Quick II radio with frequency-hopping, burst transmission and so?.

b) What is all about the different Vympel products?, Izd 170-1, Izd-180, Izd-760, Izd-300?, they were reported one year back at a conference backed by GosNIIAS, and K-77-1 (Izd 170-1) was announced to be in “state tests”…how did those missiles (170-1 and 180) really fare with the earlier known R&D made on K-77M and ramjet-powered R-77?…what happened to supposed IR-Adder and Anti-radar-Adder?

Thanks 🙂

RSM-55:

Some questions if you don’t mind

a) What’s the name of the AESA set planned for 5th Gen Russian Fighter?…is NIIP product?, did Epaulet-A test-bed have anything to do with it?, what TMR tech will use?, GaAs or GaN?. Any information?

b) Is there any information about ESM/RWR products developed in Russia after the L-150 “Pastel” series?…this seems to be the last they ever developed for airborne solutions, not bad through, superheterodyne receivers, and some niceties, but that’s a 1982 project. Aside of Avtomatika (TsKBA) who else do this kind of work?…I know ECM are researched by KNIRTI and TsNIRTI in airborne uses. This question applies to any RWR for any new russian fighter (Su-35, Su-34, etc)

c) Any info on new datalink/NWC solutions?, last I have ever heard was “MSPD”, you can read something about at: http://www.gzas.nnov.ru/produkt/avia/r11.htm
But I don’t get very good the specs, per example, what’s the transmission rate?, can you comment on it?

d) Why have been so many announces in the press about the bad state of the PAK-FA program according to you?

Thanks 🙂

French troop et all:

Is there any info about:

RDY/RDY-2: TWT peak power, TWT average power, TWT duty cycle, kind of TWT, number of TWT.

Aperture diameter of the aerial (for RDY/RDY-2)

I don’t think some of those dates are so much difficult to find, but my french sources are pretty lack.
