    Ahem… I made that one and posted it here in the Frankenplane Prototypes thread. 😀

    But thanks for the feedback.

    flat nose, bay, canted tails is some of the things stealth jet has. su47 only has a bay, a curved but not s duct. su47 duct is more like the american f5.

    Son, low radar cross sections and low EM emissions define stealth jets, not the way you achieve those characteristics.

    And FYI the Su-47 had serpentine ducts (and so did the 1.42/44). You don’t need them to twist all the way to hell and back for crying out loud, the whole point is to hide the compressor face from direct emitter LOS (from typical approach angles) and absorb whatever gets in there (or cause it to die out through destructive interference). The less of a twist the better, in fact, as them twists take up a whole lot of space and you also don’t want to eff up the airflow too much (and less effing up while keeping a good twist takes up more space, note how it’s always a matter of compromises between several factors when it comes to aerospace design).

    And again, you don’t necessarily need serpentine ducts to achieve this anyway, there are other ways. Ideally you’d want a somewhat straight duct that still remains stealthy somehow…

    The Su-34, yes. That’d look awesome, same goes for Su-25. Well, not in black but in that dark matte grey thing. The watered out eggplant-baby blue combo is absolutely hideous in my opinion.

    Il-76/476 sure would look good in it too, or would that be too C-17ish? Well, not a bad thing in my book.

    Hmmm… What else. I was going to say MiG-29SMT/UPG/whatever, but the “new” splinter schemes do look pretty fresh.

    Tu-160 and Tu-22M look good the way they are if you ask me. The white swan is the white swan, after all, and the contrast to Blackjack has always been cool. Besides, anti-flash white reminds me of one of my favorite jet bombers of all time, the Victor.

    If I was to change something about them, it’d be the way their names are painted up front. I guess I wouldn’t object to them being painted darker either, but I think I’d find that boring somehow. Anyway, I don’t really know how I’d rather see the names depicted anyway, so whatever. Besides, the traditional cyrillic and the VVS stripes strikes me as very Russian, so while I prefer a more toned-down approach the aesthetics there are probably more in tune with what they like.

    One thing I would love to see is a low vis roundel though… Akin to PAK-FAs, but all gray.

    Sorry, an entire post with random opinions. Bear with me, people. 😀

    Is it the same shade as the new VVS choppers? If I recall correctly that dark matte paint had some absorbing things going on, I can’t remember if it was just IR or both IR and radar.

    Other than that, it reminds me a lot of the B-1B and the F-15E, perhaps a tad darker but then again there are shots of Strike Eagles where they appear almost black so lighting has a lot to do with it.

    Such a shame that Sukhoi guys are apparently just a bunch of n00bs and dont read forums like these that are full of experten. 🙁 Wish this would be news only thread, and not “tired old discussions thread”.

    Yeah, I’ll second that right away. It’s a news thread and that’s what we ought to discuss. I think that this Tigershark dude is just out to provoke with his short sighted rambling and I’m actually a tad ashamed I fell for the bait.

    As far as news go, love those hires photos KnAAPO put up. It must’ve been freaking cold during T-50-3’s inaugural flight, by the way:

    Lush contrails despite what I’d assume a pretty moderate altitude.

    This question must have been asked a billion times before but… Why do they keep insisting on trying out their new toys out in the middle of the Siberian winter?

    They could have still maintained engine separation and used the central area for weapons & fuel, they still may 😉

    Sure – but that’d mean a far fatter fuselage cross section, possibly inducing more drag and negating or diminishing the central fuselage and “tunnel” lift contributions.

    Besides, the preliminary data already suggest superb range figures and while some have expressed their concerns about the internal weapon storage capacity I’d say it’s well adequate as a standard air-to-air load for a “stealthy” mission in an aircraft its size (2 SRAAMs and 4 M/LRAAMs that very well might be extended to 6 eventually, sort of per the F-35 example).

    In short, I don’t think they went with the Flankeresque approach simply because it was Flankeresque and they knew it like the back of their hands. That “risk” take on things might have been a minor factor, sure, but it’s not like the design’s completely devoid of benefits beside that…

    russia wanted low risk so chose similar design to flanker.

    A more reasonable assumption would be that Russia (Sukhoi, in fact) wanted the engines widely separated to allow for independent thrust vectoring to augment the aerodynamic control surfaces and possibly also for better safety. Add to that the lift vs. drag advantages and so on. In short, they wanted kickass performance and they undoubtedly do believe that they have the peripheral technology to bridge any kind of “stealth” gap vis a vis the competitors.

    Of course the Flankeresque approach is something Sukhoi is most familliar with and thus could be regarded as an “low risk” approach seen from that perspective, but we do have reason to believe that the current choice has deeper implications than that.

    What? – that they ‘re-fuelled’ or ‘in-flight refuelled’ ???

    They might (and obviously would have to) re-fuel on the ground using US systems.

    But they could not have re-fueled in flight – because they were not equipped to do so.

    Ken

    Even if they had IFR-probes in place, would the Russian P&D IFR system be compatible with its NATO counterpart?

    I think attack helos are a horrible mis-spending and are only justifiable
    for certain SOF operations, where some additional firepower may be warranted.
    so i vote for Mi-24 or Mi-17

    I second this. The sound move would be to spend their money on multirole helicopters. The NH90 might be too expensive for them (and has been plagued by delays and what not) but something along the lines of the Battlehawk or the Mi-35 would do the trick. That, and/or COIN a/c with decent rough airfield and STOL capabilities (there are tons of them and they’re not too pricey) would be a much better investment.

    Don’t get me wrong, dedicated attack helicopters do constitute an asset to be reckoned with in many situations, but their reputation is well over-inflated. Considering the narrow niche they fill in I find it hard to justify such costly acquisitions by armed forces the size (and especially in the situation) of Iraqs. AHs should be considered a luxury for those who have everything else fully covered and still have heaps of dough over for that extra little bit of icing on the cake.

    But if they really do want them for some reason, Mi-28 is probably their best bet. To me it just sounds like Iraqi top brass having watched too many US action films though.

    I wish I had your photoshop skills. My goal is to graft the head of an Vought XF8U-3 Crusader III on to the body of an English Electric Lightning F.6 and add in the F-8E’s Y-racks with Sidewinders. Go with the overwing tanks. That would give it a front heavy load of 4 Sidewinders and 3 Sparrows/Skyflash missiles.

    I have found this crazy XF8U incantation mixed with an F-4: http://i37.photobucket.com/albums/e68/GTwiner/vought-f8u-3b.jpg

    That looks crazy indeed. 😀 I’ve always loved the Corsairs and the Crusaders, especially the two seaters, like TA-7C. I can’t really put my finger on why.

    I like the sound of what you are describing there, by the way. Racks/pylons in “odd” positions (that is, other than underwing/underbelly) has always fascinated me. I think it looks awesome.

    I decided to contribute as well, I hope that’s okay. Here’s my Frankenfitter:
    http://i.imgur.com/pi3qm1h.jpg

    It’s a Polish Air Force Su-22UM (original image here) mated to a fattened-up F-4 Phantom radome, A-4 Skyhawk side intakes (source) and the IRST/FLIR of a SAAB J35J Draken (from my private photo collection).

    …Oh, and it’s in something reminscent of 1960’s USAF markings. Photoshop galore.

    I know that project existed, but doing it 20 years earlier AND putting the rotor in the middle of the airplane is a pretty stupid idea. Helicopters can stabilize themselves thanks to the low point of gravity. This howver is a death trap.

    Try 5 years earlier (Triebflügel in the works 1945, Hornet flew 1950 or so). :p And the Hornet was not the first successfully flown tip-jet rotorcraft either (in fact, the Germans already tested the concept in 1943 with the successful flights of the Doblhoff 342).

    But yeah, obviously there were inherent stability issues with the Triebflügel design (and the Heinkel Wespe etc.), especially noticeable in the planned landing sequence. But I don’t for a second believe that it would have been impossible to achieve, especially considering that rather similar VTOL aircraft did fly in the 1950’s in both France and the US. However, it was a rather impractical approach and it was soon abandoned. At least one of the US tailsitting VTOL projects was fitted with makeshift horizontal landing gear to allow for a conventional horizontal landing, so I think that was the main issue really.

    Wtf #2… how was the fuel expected to enter the engines at the end of the propellers?

    Look no further than ramjet-powered helicopter blades. One (quite unsuccessful but at the very least, functional) example:
    http://en.wikipedia.org/wiki/Hiller_YH-32_Hornet

    Goes to show that it’s possible, though.

    That’s much like the double delta F-16XL

    Or perhaps most like a mix between the MiG-21I “Analog” and the MiG E-8 (both of which were MiG-21 derivatives):

    Does anyone know how things are progressing at LII ? There hasn’t been any news about T-50’s testing in months (i mean pictures on sites like RP). I think the last big thing that happened was 51 returning to flying …it seems terribly quiet again.:confused:

    Sukhoi reported on October 16th that the T-50-4 will conduct its maiden flight from the factory air field (KnAAPO) in the “near future”. That’s the latest piece of news that we have.
