Not new, but relevant:
The ITAE and its partners use plasma technology for applying ceramic coatings to the exhaust and afterburner. Multi-layer coatings formed from microparticles of dielectric, metal, or semi-conductor material are deposited by an arc-discharge plasma under atmospheric pressure. Challenges include the need to keep the ceramic bonded to the metal structure over a wide temperature range (600°C to 1,200°C), despite the fact that the materials have widely different thermal-expansion characteristics. The coating materials also need to maintain constant electrical characteristics in the face of widely varying temperatures. Researchers describe this problem as “partially solved,” and engines treated with ceramic RAM have already been flight-tested.
Happiness is…
Thanks for the pics Quadro, fantastic!!
Without drawing lines or debating the nature of those yellow, slightly convergent rectangular panels (which I believe to be the ‘roof’ of the S-duct), the barrel of the cannon is directly line-of-sight of the centre of the compressor face.
There’s your lateral curve PiBu ;).
ok, this is a much improved version, more accurate to scale thanks to beloved MKI, still far from perfect though.
Here’s something else. If you look at the pic below, there’s ample room for a (staggered) central 3rd pylon between the two existing ones- use their clearance from the bay wall as reference (also note the T-50’s bay is wider):
Hence, the pylons should look like the Raptor’s arrangement, but 3×3 in tandem, instead of 6 abreast. So, imho, your latest rendition is accurate. 🙂
I gave it a try, and appearently, 2 R-77Ms is perfectly feasible, but 3, in an asymmetric manner, like R-37s on MiG-31Ms, is not. 3 x R-73Ms is also feasible.
I made two models with two possible configurations, in the first one, it is impossible to fit 3 R-77s asymmetrically.
Are you sure? I read somewhere that the Su-35S will have dual (abreast) launchers for the R-77M between the nacelles. Question is, how wide are those bays on the T-50?
Su-30MKI for reference:
