In Deino's enhanced pics he posted it looks like it works the opposite of this. The three yellow marks outside seem to be the ends of a curved rack that rolls out from the bottom to reveal the rail.

Dear MiG-29 !

Dear Deino

I have never seen such a long-winded warning from a mod. You know, when a mod see members (doesnt matter here who they are) constantly ignoring his requests, he should take action to stop it. I am not a mod, and dont advocate banning members, but some action should be taken at some point.

Forgive this little rant, but its just that your plight in this thread is becoming painful to see.

Yeah, the entire set up looks overly complicated. One main door, three smaller other doors. I'd prefer they'd just shove the missile out, and be done with it.

But the idea that they could use it to hold some kind of external weapon is interesting. What would they hold out there?

Supersonic ASuW missiles, air-dropped ASW torpedoes, long-range ARMs, electro-optical search pods, EW pods, etc.

 

[leibowitz]

If I remember correctly, an SRAAM has to be able see the opponent aircraft in order to get a lock. This requires the missile to be stuck out of the aircraft throughout the WVR engagement, not pop out at the last moment. If the animation is an accurate depiction of how the side-bay works, then the J-20 can basically change mode by going from pure internal carriage to pure external carriage. This solution would indeed have a lower drag penalty than F-22, since the latter has to deal with drag associated with an opened weapon bay.

That hardpoint solution is extremely clever. It basically allows the J-20 to have the benefit of 'holding open' its internal weapons bay without substantial loss of aerodynamic performance, which is something no other 5th-gen fighter can claim to do.

Apparently for their middle weapon bay they have 4 multipurpose pylons to fit either long range AAM or other munition which are dropped from the plane, but they also have two rails on the sides of the weapon bay doors to fire either short WVR or long range AAM directly from the rails, but cannot be used to carry other munitions. I wonder what arrangement they use for those two side pylons, whether it is similar to the side bay.

Also could they be doing this because of possible adverse effects on the canards aerodynamically if they keep the door open for extended time? Their design requires complicated coupled actions between the canards and the LERX.

Certainly any theory of J-20 being a bomb truck can be dropped this bird is very serious about air-air combat.

I admit that was a noob question, so I appreciate the straight answer.

Thanks!

It's also possible the larger bottom bay door can also be closed with the missile rail extended out.

Personally I don't think such harsh measures are warranted. While MiG 29 may be long winded at times and gets off tangent here and there, he does offer alternate points of views and I know he and Engineer has a love/hate relationship going on like an old married couple. Far from speaking for him but I have a sneaky suspicion our dear Engineer will be bored to death if MiG 29 is not here to offer his counter arguments...

anyway just my 2c.

The issue isn't that MiG-29 providing alternate viewpoints. The issue is that after his viewpoints have been debunked, by statements from Chinese engineers no less, he drags in irrelevant information in order to float his fantasies. For example, the SAC's engineer already showed canard allows J-20's competiting design to achieve control at 65° angle-of-attack. He then points out how Russian aircraft can do Cobra which is completely irrelevant.

That tactic is a

Anyway, back to the J-20.

I think adverse effects to the canard and LERX would be unlikely, given the door is situated beneath and not at the same level to those aerodynamic features.

As for the theory that the rail would allow other weapons to be carried externally, I think that is pretty much an impossibility. One needs to remember that this is a rail, not a bomb rack, which pretty much limits the carriable weapon to SRAAM.
