…I don’t see here mention of any _practical incorporation_ of the CNT and fullerenes on T-50 again.

Созданный углепластик КМУ-18, содержащий в своем составе астралены, находится в стадии паспортизации и предназначен для использования в конструкции планеров самолетов ПАК-ФА (2-й этап), SSJ-130, МС-21.

Для защиты от поражения молниевым разрядом конструкций из углепластика, выходящих на внешнюю поверхность планера (составляющих > 50%), во ФГУП «ВИАМ» для изделий МС-21, ПАК-ФА и ряда вертолетов разработано молниестойкое покрытие, представляющее собой углепластик, содержащий в своем составе астралены и фуллерены.

[FGUP VIAM]Produced CFRP KMU-18, containing in its composition astralenes, currently in the process of being certified and is designed for use in the airframes of PAK-FA (Stage 2), SSJ-130, MS-21.

For protection against lightning strikes/discharges on structures of carbonfibre of the outer surface of the airfame (amounting to >50%), FGUP “VIAM” has designed a lightning-strike protective coating for the MS-21, the PAK-FA and several helicopters, which is a carbon fibre composed of astralenes and fullerenes.

If you would kindly note the date of the article.

I see here a page from presentation of Indian DRDO Defence Materials and Stores Research and Development Establishment (DMSRDE) materials developed for Indian UCAV and (A)MCA from AeroIndia 2013 taken at the Trushul blog. What has it to do with PAK FA?

Nope, wrong doc. I think you’ll find my para-phrased translation of ‘Section 2.7’ not too inaccurate, as you have already declined to do so.

My humble wish was just make you think of separating someone’s whishful thinking from the realitiy.

My slippers! How they laugh!!

“Master f, I googled for Indian RAM and…”

“-Did you google in Hindi? No? – Well it can’t be true!!”

“Master, are you still sure about the side-arrays?”

“-Positive I tell you! Positive!!”

Do you think final product will use the GaN modules? I recall something of Rostec looking at making modules cheaper and smaller. I guess that is GaAs modules?

That was ‘NPP Istok’s’ development of GaAs pHEMTs – specially doped GaAs MMICs resulting in significantly increased power output, as a cheaper alternative to GaN:

Mikran & TUSUR have developed a method to substitute the precious metals in the GaN chip’s substrates to reduce cost.*

GaN materials and microwave integrated circuits will become much cheaper when (already) LEDs and (later) 5G/IoT technologies become ubiquitous.

Lol, and where is confirmation here that CNT/fullerene RAM is used for T-50?

It’s not. T-50 and other LO-pimped a/c here are using a family of ITAE-developed RAM.

Well, unlike yourself, I’m sure the folks at ITAE are aware that the lightning shielding effects of CNT/fullerene composites aren’t their only *special* property, that’s even before they add their own layer ‘recipes’:

В ИТПЭ РАН разрабатываются методы формирования упорядоченных и неупорядоченных систем на различных масштабах их линейных размеров (нанокомпозитов, макроскопических сборок для фотонных кристаллов, макетов структурс отрицательными диэлектрической и/или магнитной проницаемостями).

Фактически сформировалось новое направление в материаловедении – технология композиционных
материалов с многоуровневой организацией

Sepheronx, it is a derivative of this:

http://www.freepatent.ru/patents/2482149

Hence a close relative to the type used on the F-35 (and later retrofitted to the F-22).

Jo, I’m just trying to tell you (as I did 3 years ago) that let’s say not all of the Northrop Grumman patents issued in last 5 years have direct relationship to B-21. As well not all of the patents and papers issued by VIAM, CIAM, ODK, Saturn, UMPO have ties to PI.
Not all that fancy videos produced by scabs from Rostech or Rosnano have impact on real life. Etc.

I’m sure you can find it in your heart to forgive my mistake of thinking they’d use CFRP fan blades (however modified), having been misled by an ‘NPP Salyut’ publication that detailed such research for military turbofans. Back to actualities…

It’s all very well that Pratt and Alcoa have pioneered the aluminium fan blades for the PW1000G series of geared civilian turbofans, but the question you have to ask is how have ‘NPP Motor’ and UGATU achieved the same for the Type-30 LP comp.?

The latter will have nearly 3x the rpm and will hence require much higher strength and creep-plasticity thresholds. In fact, the problems would be the same as those encountered by ‘NPP Salyut’ during their CFRP fan tests for a fighter engine.

If you care not for the video above, then perhaps this link (page 2) will strongly hint at their chosen aluminium [composite] blade strengthening method. Obviously, the radar absorption ‘by-product’ is a highly desirable property in the case of the Type-30.

to be continued…

Oh you!! Could’ve waited a few days to mark the 3rd anniversary of that post!

Anyways, re: ‘stealth compressor’ in the intervening years I also posted this:

Perhaps you (being a native speaker) could translate the important/relevant bits in the video yourself – as your protégé thinks VV751P* is steel (!) and to this day can’t figure out the meaning of:
