Teer, this is an extract of an interview with Yury Beliy, General-Director of Tikhomirov-NIIP @ MAKS 2011:
Не забываем мы о предшествовавшей «Ирбису» РЛС с ФАР «Барс», находящейся в массовом серийном производстве и широко поставляемой в составе самолета Су-30МКИ и его модификаций вооруженным силам Индии, Малайзии и Алжира. Как известно, партию подобных самолетов, названных Су-30СМ, решило в ближайшее время заказать и российское
Минобороны. У нас уже есть контракт с компанией «Сухой» по созданию варианта РЛС «Барс» для этих истребителей.We haven’t forgotten about the radar that preceded “Irbis”- the “Bars” PESA, which has been in mass serial production and widely supplied as part of the Su-30MKI aircraft and variants for the armed forces of India, Malaysia and Algeria. It is well known that the Russian Ministry of Defence has decided to purchase such aircraft (Su-30SM), in the near future. We already have a contract with ‘Sukhoi’ on the delivery of a variant of the “Bars” radar.
Участвуем мы и в программе модернизации Су-30МКИ для индийских ВВС. На первом этапе этих работ предусмотрено дальнейшее повышение характеристик РЛС «Барс» с имеющейся ФАР, а затем возможно оснащение ее АФАР.
Но мы считаем, что такая модернизация «Барса» должна быть увязана с программой создания РЛС с АФАР для совместно разрабатываемого Россией и Индией Перспективного многоцелевого истребителя пятого поколения ПМИ, чтобы применить полученные наработки по радиолокационному комплексу с АФАР для последующей модернизации строевых самолетов Су-30МКИ.We are participating in the modernization programme of the IAF’s Su-30MKI. The first phase of these works calls for increasing the performance characteristics of “Bars” with the available PESA, and then it’s possible to equip it with AESA.
But we believe that such a modernization of “Bars” must be linked with the creation of the AESA radar being developed jointly by Russia and India for the PAK-FA/FGFA, in order to apply the received experience to the AESA intended for further modernization of the Su-30MKI units.http://take-off.ru/pdf/10_2011.pdf
(page 35).
I’m not absolutely certain that the Phase 1 upgrade will include a new “Bars” antenna, but the RuAF has ordered a “variant” of the “Bars” and I would doubt NIIP could achieve such an increase in reported performance by retaining the old antenna combined with ‘Irbis’ back end and software upgrades.
This is believed to be the new ‘Bars’ array (as you can see the assembly and finish is far superior to the current version):
…or maybe there’s an outside chance that a gimbal-less ‘Irbis’ array will be fitted (above right).
Nice Indeed. They need to ruggedise the displays and increase the pixel life if it is not high enough already including avoidance of dead pixels. By the way what is Hamilton doing in HeliRussia, the stand looks out of place if not for the two gorgeousnesses standing there. No pics of the crocodile? The Monitor on top is a Panasonic.
The display appears to be LCD with pressure operation, as opposed to electrostatic a la iPad- so should be OK. Below is what appears to be Russia’s first commercially available OLED EFIS display. This may suffer from premature blue LED degradation, a problem believed to have only recently been overcome by World leaders SAMSUNG.
Erm…did you mean Vitaly Petrov?

The only exceptional thing there is noise and interference elimination of having all components on chip and the reduced dimension, probably for space constrained applications. HFET/HEMT are known to scale well uptil 600 GHz in power and current gain, so there is so much headroom available and no need to get all BiCMOS with it complicated fabrication process.
Interesting insight, thanks. Unlike yourself, I’m not an industry professional- I’m just a geek. TowerJazz and DARPA have established a roadmap (GRATE) where they plan to upscale BiCMOS HBTs up to 500GHz from the current tested 110GHz so we’ll see how they fare.
SiGe BiCMOS research is quite mature in both India and Russia, stretching back at least a decade in the latter. I don’t think the Indians would struggle too much to design such a device (Indian chipset engineers design some 2,000 chips per year for the large foreign SC companies). Of course, fabrication is another issue, and would require significant capital investments.
However, as I understand it, SiGe BiCMOS chipsets have a considerable cost advantage over GaAs MMICs (and hence GaN which are 2-3 times more expensive than GaAs). Given the future commercial uses of SiGe superseding GaAs and GaN in both cost and performance, SiGe phased arrays must be high on the wish list of many future defence projects- if the tech delivers.
Back OT, a relatively recent shot of ’52’. Note the port engine nozzle without ceramics and what appears to be a ‘charcoal-matt’ finish:
c/o paralayiboards.
I doubt the pilot would need to show off the plane if sales to the said domestic operators had already been sealed.
Maybe (after requesting permission) he descended to break stratus/lenticular cloud base on Mount Salak, Indonesia’s NTSC reports the crash site is between 6,100-6,200ft above SL.
An eyewitness claims the SSJ was flying very low and veering from left to right. Perhaps upon breaking the cloud base, the pilot found himself in a mountain range- and panicked. In which case it could be an ATC issue as opposed to pilot exuberance.
RIP.
