^^ouch…

UPD: Here is the same photo in higher res.

In terms of aerodynamic configuration, T-50 and F-22 both are relatively traditional designs. While T-50 is an ideological successor of late Flanker’s configuration – an integral triplane with air-intakes under the carrying fuselage, F-22 is a successor of F-15 – an integral monoplane with side air-intakes.

Widow is a different story – a monoplane with symmetrical delta-wing and tail control surfaces mutated into the pair of large, all moving stabilizers with a high angle of incline. IMO, Widow is the most unusual design among all three.

But of course, in terms of technology and flight/tactical characteristics, each design has its own advantages and disadvantages.

No , the gold coating act as the reflection layer but the absorbing panel already included the reflection layer (ITB010 ) and absorbing layer (ITB0390) in it , in other words the 60% transmissivity of the glass panel is with both reflective layer , absorbing layer and the Polycarbonate

Ah, so this is an optical transmissvity of the whole panel. Now i see it in TDK doc. Thx for correction.

all we know is that F-22 canopy used a thin layer of indium tin oxide, no official information about what used on F-35 or B-2 or PAK-FA , or J-20 canopy or what kind of RAS they have ..etc , but that quite normal that there are classified aspect when it come to military equipment.All we can do now is speculate

Actually, at VIAM webpage i posted earlier, there is a mention of RAS polycarbon glass. But PAK FA canopy is made of silicate glass. I wonder, is there any sort of RAS layer in its stucture?

70% transmissivity is very good , not poor at all , the transmissivity of Have glass on F-16 isnot any better , the main component of this commercial radar absorbed glass are indium tin oxide and Polycarbonate which are actually quite common on fighter canopy

I dunno what about US made canopy glass, but Russian polycarbon glass used for canopy glass production has 90% optical transmissivity.

While TDK ITB RAM has “over 60%”. https://product.tdk.com/info/en/catalog/datasheets/e9e_bdj_003.pdf
It’s a horrible number, not speaking about other mechanical characteristics which are unclear and may be not sufficient to by used for canopy production.

So, i wouldn’t be so sure that F-22 and F-35 canopy glass has such RAM layer. At least – there is no any mention of it in the literature i ever read.

No, the RAM is placed between the canopy normal frame and the inner gold coating , you can imagine it like this , the canopy have several layer , the outer most layer is Acrylic then come Polycarbonate , after that is the RAM coating , then the inner most layer is a thin layer of gold to prevent the radar wave from entering the cockpit .

Does F-22 or F-35 canopy contain such a RAM layer?

Yes.. I have seen it in a lab, with test equipment worth thousands. It is possible.

Didn’t get it. What you saw in a lab?

Why the turrets look like this is beyond me..

IMO, the answer is very simple. In engineering(at least in Russian one 😎 ), if something doesn’t affect overall characteristic significantly then no one bother. In other words, if the RCS of these turrets isn’t significant in comparison to overall airframe RCS, then no one bother.
