Shenyang next gen combat aircraft thread

Is that the case? My understanding is even the F-22 has to open its side bays in order to allow the AIM-9X's own seek head to have a clear line of sight to acquire a lock-on. For the J-XD, any sensors mounted on the bulge of the side bay doors will have a very close field-of-view to the internal missile's seeker head which may allow lock-on data to be transmitted seamlessly.

it's yes and no.
All quick bays other than J-20(it can outright stick wvr missile out and do traditional LOBL, too) work this way:
missile seeker starts tracking within the bay(from external angular feed, it by itself of course can't see anything yet), and when it gets out of the bay, it has immediate lock.

There's no need to co-locate sensors to get it work, it's very simple geometry anyways.

J-XD The Flappy Bird 0

Wondering how big is the nose % wise compared to say J-20.

High five!!


Expected. The strains the wingtps need to endure will be insane.


Actually I'm not too sure. 人畜无害遥感星 claimed in a reply (under a now-deleted Weibo) that a HOBS missile is inserted diagonally to reduce the SWIB door length (think the F-22).

Diagonal stowing and an F-22-style launch system would explain the lack of trapeze-system mini-holes around the rim of the bay doors like there is on the J-20 (unless they had fully committed with LOAL missiles). Although its uncertain if we could see such detail at the resolution/quality of currently available photos.

The biggest question here though is what that bulge on the bay door is. If its a weapon bay door, would putting a sensor (or something else heavy and/or requires extensive wiring to an internal component) on something that needs to swing out wide during high speed flight (i.e., put a lot of strain on the door hinges) be a good idea?

Provided that the details of the J-XDS from the photo processing is accurate and that the J-XDS has similar length as the J-20 family (~21.2 meters), that means the IWB(s) are about 4.5-4.7 meters long. That's certainly not anywhere close to be significantly longer than the IWBs on the J-20/A/S.

PL-17 certainly will not fit into the IWB(s) of the J-XDS, so I suppose we can put that contention to rest.

In addition, there is definitely no side IWBs present on the J-XDS. So, all we can hope for is for the IWB(s) to be wide enough (to fit more AAMs) and/or deep enough (to double-stack AAMs).

It's reasonable to think that next gen fighters will be accompanied by next gen missiles (I've heard rumors supporting this). So we shouldn't limit our thinking to just fitting the PL-15 or PL-17, perhaps something like a 4.5m PL-XX

On the other hand, if larger IWB size is desired and more space is needed, I wonder if we’ll see PL-17–sized IWBs on the associated CCA. Perhaps the philosophy differs significantly between carrier-based and land-based aircraft.

J-20 and J-35?
Length is not the only way to improve missiles. Strictly speaking overly long and slender weapons were born by external carriage.

The only similar example I can think of is the YF-23s intakes?

What similarity? The small hoes on the fuselage for boundry layer? JF-17/FC-1 and J-10 all have it. Other than that, in terms of the way air flow is handled YF-23 is the furthest from J-50 than anything else.

JF-17

You just proved my point with the photo, JF-17 still had DSI bump where as J-50 and YF-23 don't.

Your post was "The only similar example I can think of is the YF-23s intakes?" which was in response to "Boundary layer suction tech on the intakes??" I failed and still fail to see your point being about non-existing of DSI bump. And my post is in direct reference to "boundary layer suction".

KUMA from weibo took a stab at drawing the intake configuration based on the recent images. Perhaps the groove is a bit too deep though.
