TomcatViP[…] the inlet duct in it’s entirety either built of CNT RAM laminate or more simply modified with MWNTs and then the canted compressor would reflect any incident waves reaching it into more of the same RAM. Even taking a peak absorption of -21.9dB for the fan face (imho) would be sufficient, however if you google-translate the patent above [6], it has a polystyrene foam core, polystyrene foam modified with MWNTs is used by a major Russian institute to line the walls of its brand new anechoic chamber:

Like this.
[ATTACH=CONFIG]221810[/ATTACH]
The compressor is build to be radar transparent mostly to give space for wave reflections, absorbing only the creeping part of the incident waves (using a metallic edge to conduct the wave all along the blade and facilitate its energy absorption within the foamed material).
We’re not talking hypotheticals anymore, but hard facts & data (it’s all there, above). I’m certain of similar solutions for US 6G warplanes as per their artist’s renditions.
The more I am looking at the PAK-FA, the more I see in transparency the 22. Those design are fairly similar. A more aggressive approach, even brutal and focused on the very needs of the VVS (sry!). Some improvements are built in obviously.
So, the 6G, IMOHO couldn’t be considered as a try to reach a similar level of technology. No,
The ADVENT engines are in fact a more radical step beyond what might be the 119 and what the 117 is sporting, like if you want, and just to make a stupid comparison, a wedding is after an initial engagement.
Hence, perhaps, the focus toward an early switch to the new engine for the first series of T50s and, even more (unlikely?), the recent Indo/Russian disputes regarding the future technology rights.
Dionis, nein!! nein!! 9!! I’ve long said the laws of Bernoulli and Navier-Stokes preclude the use of a blocker, just see the separate patent for the T-50’s intake and duct. Instead, a beautifully elegant solution.
Actually, the Su35 seems to hve some kind of blockers (even if they look like shy kids in comparison to the pictures that hve been posted in this thread ).
The 18 allegedly sports some also.
Note to the reader:
All the above from myself are wild speculations!
TomcatViPstrange..havent’ seen a single image of the upgraded Mirage-2000H anywhere..this is a big program and Dassault chooses not to release a single pic?
Dassault adverted loudly years ago that it won’t re-open the 2K production line. There was no place/interest to run both products at the same time.
Perhaps it is as simple as that.
TomcatViPAn interesting photo report from KnAAZ showing Su-35S and Su-30 under construction:

Very good stuff. Both documents!
Regarding the Yak, that’s a really neat little bird. The propulsion package (inlet/outlet) and the gun loading process hve really impressed me. A good alternative for rough field/CAS op. … Cost less than a Tuc and she does speak a perfect English!
Ouuch. I can see them shipped like eggs boxes in Sth/Cent Am and Africa. Just add a free vodka bottle in the glove box for the pilots wings ceremonial and she would be like the utmost perfection!

TomcatViPThe last one is a SCRAMjet. The compression surface hve to be convergent in supersonic flows. A Ramjet would hve had a convergent/divergent throat 😉
The PDE type combustion chamber is certainly related to a non carbon fueled engine.
Thx for the translation
TomcatViPTERN is supposed to launch and recover from Burke and LCS classes. UCLASS is supposed to launch and recover from Nimitz and Ford class. There are range and payload requirements differences too.
I am talking about the ISR part of the mission (as 600lb does not conflict with the UCLASS specs – everybody will easily agree with that).
900nm fall in the class specified for the UCLASS (600 or 1200nm). Don’t forget that a TERN UAV will be much more flexible in term of deployability (a carrier being a strategic asset).
And I was referring explicitly to the relaxed version of the UCLASS since nothing tell us that TERN will hve any major LO characteristics. Mission wise, a flexible, smaller and more kinetically dynamic TERN might step on the toes of an Avenger like platform if we speak in term of persistent ISR (just like a Predator is a valid alternative to the Reaper part of the range of its mission).
TomcatViPnah. Among the 719 problems identified by the GOA, only ~500 were acknowledged by the F35 team (LM/Military watch dog). 340+ being already solved at the time the GAO report went out.
Identifying glitches among a production process that is ramping-up is a difficult task. Many small changes are ongoing daily and it’s difficult to keep trace of all of them from the remote comfort of a government desk. You have literally to dig yourself in the production line to get a clear picture of what is really going-on.
Some stated that the GAO report is based of an old config. I don’t know if this is that much simple but I have no problem thinking that their demarche (parallel assessment in lieu of embedded) was erroneous.
TomcatViPDARPA program to launch long-range UAVs from small ships expands to five contractors

Fascinating capabilities indeed.
Regarding the Slowed rotor/compound (SR/C) as extracted from the Carter website (http://www.cartercopters.com/‎)
As SR/Câ„¢ Technology pertains to the helicopter market:
SR/Câ„¢ aircraft are fully capable of satisfying the requirements of the vast majority of helicopter missions, without the added cost, complexity and weight inextricably intertwined with systems having full hover capability, e.g., heavy gearbox, complicated heavy rotor-head / swash plate system and counter-torque device. This is because the extreme inertia that can be stored in the rotor allows SR/Câ„¢ aircraft to hover for approximately ten seconds based on the maximum in flight rpm and fifteen seconds based on maximum takeoff rpm. (By using stored rotor inertia to drive the rotor, the need to counter the torque associated with extended hover is eliminated.)
Landing Gear Capabilities
Put into the context of offshore operations, the ability to hover for ten seconds will allow SR/C™ aircraft to make safe approaches / landings on oil rigs and ships. The ability to land on floating structures is further facilitated by Carter Aviation’s patented lightweight extreme energy absorbing landing gear.
I guess we will see interesting dev in line of sight kinetic energy transmission 😉
One question however: does the TERN UAV not conflict with the relaxed UCLASS configuration ?

TomcatViPDoes the BA609 generate more power? I still think its usefully for operating at sea or in the Coastguard role.
Yes. Mathematically, long range missions is where it stands in term of reliability and on cost ground.
Here is a fun relaxing vid depicting the V280 on future OP as seen by Bell/Boeing. What is noteworthy here are the small improvements that differentiate this concept from the 609.
TomcatViPKerry and Ryabko at the Apec forum (in Bali):
– No military solution in Syria
– A push by BOTH parties for a political change of the Syrian regime in the incoming summit in Geneva
– First CW warhead was destroyed today
Both on the very same line, determined and at ease with each other positions. A sight to be seen.

TomcatViPAnd your budget is… ?
If you don’t have access to at least CNC machinery and industrial servos you can always take the Frankenstein approach with plastic pipes and radio-controlled spares for the body, a wifi action camera attached to it’s belly and a car alarm paired with some led strobes to scare intruders could do the trick.
Balsa wood works great too. Designing a robust and light structure with ribs and spars made out of that material (use a 4x4mm beam for the spar and 2mm tick sheet for the ribs for example) is pretty intuitive… and cheap.
So, pay a visit to your local shop and ask for advice before selling away your dad’s car to make a budget. 😉
TomcatViPA little off-topic, but I think the sundowners’ F4 & F14s are some of the sexiest schemes that ever graced the skies.
Oh and real men fly in high-viz markings.
