    Well- to modify the J-8 to VG you’ll have to do an “Su-17” on it, because the undercarriage goes into the wing. If you take the Su-17 wing and graft it on it to the J-8 or J-8II it looks pretty good- kinda Tu-128ish somehow.

    Well- in the 60s what other VG projects were publicly known?

    There is the Mirage G I suppose.

    I think – later on- there was the Q-6 which was based on the MiG-23/27.

    The big question is – engine.

    Given the difficulty China has had in designing a large engine, you should probably stick to two R-11 copies.

    Ermm… the picture at the beginning is of Shafagh!

    As of yet, there is no clear idea what Sa’eqeh is. Speculation is hence somewhat premature.

    Fliegerrevue is a german aircraft magazine.

    Wasn’t it late 60s?

    If so, they would almost certainly be drawing on the F-111 for inspiration, just as Mikoyan did with the MiG-23 and Sukhoi with the Su-24 (the Russians spent ages photographing it in great detail at a Paris airshow…)

    Shafagh *is*, first and foremost, a trainer. It might be a light fighter or attack aircraft secondarily, but the training role is foremost.

    I have specs for the original “Integral”. It might be a starting point, though Shafagh is quite modified from the original.

    Engine: 1x RD-33NB (no afterburner) (J-79 on Shafagh?)
    Takeoff/landing speed: 160km/h
    Max speed: Mach 0.95
    Ceiling: 15,600m
    G limits: +8, -3
    Takeoff run: 180m
    Landing run: 390m
    Normal takeoff weight: 5500kg
    maximum load: 1405kg
    Wing area: 26.8 sq m
    Length: 10.95m

    Sure enough- we can talk about the MiG-29 and its Tumansky R-33D turbofans and N093 radar afterwards.

    The design you refer to is NOT by Mikoyan. Calling it the Mikoyan I-2000 is perpetuating a mistake. If you know this, then mention it. Otherwise it seems you didn’t know 😉

    Call it ‘the design formerly mistakenly known by Janes as the Mikoyan I-2000’.

    Will the Mikoyan I-2000 rubbish never end?

    It looks like the Russian Eurasia Integral trainer design, because it is derived from it. The “I-2000” is the “Integral-2010”, not a Mikoyan design. Eurasia is known as Mukhamedov now.

    They took out a patent on that wing configuration….

    Here are the Integral design and the later Vityaz 2000 design from the same OKB.

    What about the SARH version of the PL-2- isn’t that the PL-3? It would need only a simple MiG-21MF pulse radar in the nose.

    As we are dealing in what-if scenarios, you could mount pretty much anything.

    What about – Russian R-23T goes AWOL during early 70s, lands in China, where it is copied and used as a “Super Sidewinder”?

    Or- building on the Mirage looks- they license build/steal the Matra 530 AAM for it?

    This is the only possible BVR weapon in that timeframe. It was a reverse engineered AIM-7D (not B as the site above suggests) based on Vietnam war booty.

    Please note that the M53-P2 might be reliable, but it is also a less than stellar performer.

    Designwise it is a simple single shaft turbofan with a bypass ratio of 0.4.

    Compression ratio is a mere 9.8:1, which is so far behind the leading edge as to be embarrassing. It is heavy and underpowered compared to any contemporary engine.

    SFC in mil thrust is 0.90 compared to 0.77 for RD-33.

    So it ought to be reliable, given its complete lack of any high tech features!

    The Kaira still is from a Russian language site, I don’t know anything about it. Reading the Su-25 book about the creation of the Shkval, it seems that the IT-23 TV display used for Kaira is no more than a dumb display device. The book talks about creating a new display for Shkval which allowed onboard data like speed/altitude to be overlaid onto the tv screen.

    The Relyef shot is from a video about Sukhoi, I’m trying to find out more… in the video shot, the circle moves upwards and then the cross moves up to meet it, I assume that the circle is the calculated flight path and the cross is the actual flight path.
