Shenyang next gen combat aircraft thread

[Neurosmith]

Are you sure, "The photos definitely show two tailfin positions"? The one from the side clearly shows the tail - if there is one - folded horizontally, but all others could be anything IMO!

If you compare the following two photos, you will notice that the top photo shows a much more prominent tailfin in the horizontal plane than in the bottom photo, despite the latter being taken directly at the ventral side of the aircraft. The bottom photo shows the tailfin in the "up" position whereas the top photo shows it in the "flat" (or "stealth") configuration.

SHADE (Shenyang Air Dominance Enforcer) is less ambitious than CHAD because there is always the possibility that CHAD could be the wrong design philosophy or the development process could hit road blocks. You need to have something to fall back on if things don’t work out.

I think might be due to upper management or culture at SAC. The J-36 and J-50 fulfill fundamentally different roles, so one really shouldn't be taking a back seat to the other in terms of engineering effort or design innovation.

If Shenyang's 6th gen fighter retains conventional vertical control surfaces then its program is probably closer along the lines of the GCAP or FCAS than its sister program out of Chengdu in terms of ambition, risk and cost.

We know for a fact that the J-50 has no fixed vertical control surfaces.

and i belive this one show tailfin in the "up" position too

It's a bit difficult to tell with this photo. It looks horizontal/folded to me, but I can't really tell.

If it`s in horizontal configuration,there should`n be a bright gap at the wing root.

If it`s in horizontal configuration,there should`n be a bright gap at the wing root.

I don't think it's a gap; it looks like a reflection of the sunlight.

sr, i mean bright notch shape.probaly is reflection from tailfin.
but the post effect in the photo is too pronounced, so I cannot be 100% certain.

The data provided is speculative:

• Broadband omnidirectional stealth (from Ku band to VHF) is estimated to be at least -40 dbs or approximately RCS: 0.0001 square meters (four zeros).
• The aircraft length is 22 meters, with a wingspan of 19 to 19.5 meters.
• The maximum takeoff weight is estimated to be around 40 tons.
• The top speed is estimated to be Mach 3.
• It features a large strake and a deformable Lambda wing.
• It includes a straight-axis fully movable variable V-tail (which can switch between a fully movable vertical tail and a Lambda wing configuration).
• The wingtips have fully movable winglets.
• It is a highly agile air superiority stealth fighter.
• The chin houses an electro-optical detection system window.
• It is powered by twin engines, with DSI (Diverterless Supersonic Inlet)蚌式进气口 on both sides of the chin.
• The estimated maximum total thrust is around 37 tons.
• It is equipped with two-dimensional thrust vectoring nozzles.
• It has an exceptionally large and long main weapons bay.
• There are two longer side weapon bays (for close combat missiles).
• The weapon bays can carry various types of ammunition such as PL-15, PL-10, and PL-17.
• The estimated combat radius for air engagements is between 2000 to 3000 kilometers.

Some of those specifications seem like they are just maximal, thrown out from enthusiast desires.

Decent attempt by the picture comparison (even though I think they're somewhat overestimated relative to J-20), but jeez the specs are a bit out there

Nice pictures but stats just pure guesswork so maybe it's better to not include it.

I don't think it can be measured at this point, there isn't a good reference object from the photos we have.
