ogami, there is a way in supersonic investigation that use the concept of the low leading edge angle, is based in the reduce of the lenght of the edge and the surface in contact with supersonic flow with low angles with an reduction in drag, but this is still an xperimental investigation, only that.

one sees that in this forum is a sin or a curse the “delta” word if it is refered to the f22

the trapezoidal wing is new in russian aerodesigns, i dont think that they will risk the proyect with that concept…but maybe theyre brave enought 😀

or that wonderful performance of the sabre against the mig15s in the korean war, or russian elecronics-radars sucks or that “ruskies planes have bad performance because there are more interested in SAMs”, the problem is that those myths sells very good, there many others myths about submarines and ships, politics etc…

anyone have the skemathic of the 35s lift fan gearing box??? (transmission between engine rod and fans vertical axis)

well SOC, i really dont like get into the “war sources” its very boring that “i read more books” anyway thats your opinion, those 5gs that you are saying are not subsonic, thats for sure man….

i really like speculative threads, you can post your cocepts, and discuss in a technic way, i have one idea (of many) for the russian 5th generation, i dont like the berkut concept ,i doub that those f18 wings could work good at supercruiser, but in maneuverability maybe perform better (lift vector position), anyway i preffer an delta-cannard configuration (like the mig MFI), maybe the 1.42 in fact was conceived for stealth (the prototipes looks very diferent than the production airframes) theris my 1.42 (the nose must be in a lowe position, but i dont had patience :p );

Such as?
Having large racks of weapons on the exterior of the plane just makes the plane stand out like a sore thumb on radar screens (unless they somehow make that ‘plasma stealth’ viable, but let’s not go there). Unless you want stealth weapons too.

well in the second image you can see thats an very conventional concept (only the frontal missile fin could be visible)

ink, i like to read other stuffs that only aeroindustry magazines, sometimes that “specializated” press confuse everything, anyway if you think that the berkut comes from the flanker, thats your opinion and (as i have said many times to avoid problems) i respect it.

i still think that there smarter solutions that the internal bay, anyway thats only an opinion

SOC, that “too small” argument is absurd, mig23 and su24, mig29 and su27 have the same basic configuration, the sukhoi team have said anything more about the pakfa than that classic declatarions of “it will be stealth, supercruiser, new radar,it will be the best fighter in the world”….bla,bla,bla, once they had said (i dont know if it was in fact sukhoi guys) that will be an berkut without fsw, but right now they are saying that will be a completely new aircraft (and maybe they have already selected an configuration), so we just can speculate (those 5-4 airframes) until the airframe shape will revelated maybe the next year, but maybe in the end will be an modified berkut (i also have seen an speculation with bekut airframe and vertical tails as the sukhoi lfi).

hmmm, i was wrong about the mig lfi, thanks for the correction.

well lets analyse….and speculate….. 🙂

there 4-5 probable airframes for the pakfa;

1) the mig lfi (that flying saucer)
2) sukhoi lfi (delta flanker)
3) mig 144 (russian frankenstein eurofighter-prototipe)
4) berkut genetic xperiment with f18 wings
5) f22 clone (no pleeease other raptor, noooooo!!!)

any more???? :confused: (im really confused) :p

i go for something between the sukhoi lfi- mig 144, both are similar (in the main concept), specially an delta flanker close to an f23
