J-20 5th Gen Fighter Thread V

[plawolf]

PLAN does not need to shove 20+ J-20 on to a carrier. They can limit J-20 to about 10 - 12 and fill the rest with FC-31(J-35?).

View attachment 38952

Why the need for J31 at all if you have a naval J20? J15s would make better bomb trucks, and they could beef up numbers of deep strike assets with stealthy strike UCAVs.

If a target is so well protected and/or deep in enemy territory you need stealth strikers to go after it, better those stealth strikers are unmanned as that sounds like a very high risk mission.

But TBH, I don't think the PLAAF cares as much about pure strike capability of its carriers as much as the US and western navies do.

China's non-intervention policy means its very unlikely they would need to bomb hopelessly outmatched 3rd world nations all over the world.

Their carriers are primarily for fleet defence and protection of sea based lines of communications. For those missions, air dominance and anti-shipping are the missions most important for its air arm.

The J20 will have air Dom covered, but for anti-shipping, a J31 would be little better than a J15 since it won't be able to fit AShM of any worth in its bays, and hanging big AShMs externally will destroy any stealth benefit from the airframe design.

J15s OTOH, would be able to carrier more, bigger AShMs further.

That has been a source of much serious debate in the past?? I would suggest that much depends on whether or not the PLAN shows any interest in the FC-31 as a carrier based fighter? and as Mangi has suggested the J-20 is really no larger than the PLANs J-15s which is at present, is the PLAN's single fixed wing aircraft to operate off the Liaoning.

So it would be a relatively simple move to lateral across to a carrier based J-20 for those Naval crews,,, the J-20 would be faced with the same operating limitations currently affecting the J-15. With a hook, folding wings, and structurally beefed up landing gear,,,, the J-20 would really need quite a lot of "Poop" to get off the deck, and they might well opt for a Russian OVT engine in the near term, until the WS-15 comes through its developmental testing and is operationally certified.

Considering the J-20 does give China two options for a carrier based 5 gen, and that's a great thing!

anyway, Deino has brought us back to reality with the news, that photo is an old photo, and the appearance of 2001 back at Chengdu would be news?? so, at this stage we will be waiting to see what happens, and a J-20 sporting a hook would be a big deal.

I think the current J-20's wings are too small for carrier operation for near stall speed carrier landing. They have to significantly enlarge the wings of J-20 like the F-35A to F-35C.

An interview with Liming by CCTV4 seems to confirm that J-20's engines are assembl d domestically.

What is meant by "assembled?" Is it Russia ship all parts in kits to Chinese factory where the final assembly and test are done?

The J-20's wing area is not small...

Absolutely not a small wing.
you have a Delta wing equal in size to that of the Pak Fa or F22 combined with Canards as large as the Tail planes of the F22 or Pak Fa and a lifting body Fuselage.

All great thoughts gentlemen, and I'm really getting a little excited thinking about PLANAF J-20... could somebody do a little project, and show us what it might look like?? and I would suggest the "Primer Bird" colors to start, adding folding wings and heavier gear, possibly a little larger wing, and of course the lovely Hook?? as well it would be interesting to see OVT as well!

F-22 and Pak FA are not carrier aircrafts.

Navalizimg the J-20 almost certainly must involve major redesign of the aircraft's aerodynamics, under carriage, and aircraft structure. Several most plausible changes are: 1. Enlarged wing with much larger high lift devices on the trailing edge, possibly double flaps or area expanding translating flaps. 2. Wing and possibly canard folding hinges. 3. Greatly strengthened landing gear, with main gear possible modified to move the wheel significantly further back to retard aerodynamic pitchup during catapult launch, and avoid tail strike in case of high AOA deck landing.

Also, I don't known off the top of my head how long Su-33 is. But su-33 in length and height represent the utmost the kuznetsov class were designed to handle. If the J-20 is longer than the Su-33 with folded pitot tube, the. The chances are the navalized j-20 must also either be redesigned with shortened nose profile, or have hinged and folding nose radome.

No need to start a "range war' here Chief, we are just speculating, so speculate away, maybe find someone who could illustrate your concept in "primer bird" colors, seems to show detail so much better,,,, so show us your "proof of concept bird?" LOL

Good point. Is it "Assembled" or "Produced"? Is it a locally produced WS-10B/WS-10G or locally assembled Salut variant?
