J-20 5th Gen Fighter Thread V

Well, I think you're giving him wayyy to much credit on how much he knows about engines (when WS-15 will be ready) or whether he has the common sense to not post BS to fool people. But I see your hypothesis is opposite.

So... what's the plan now? Because of this article, divert scientists away from other projects (maybe WS-15) so we can open a project for testing WS-10 on J-20? Then in the end, have AL-31 J-20, WS-10 J-20, and WS-15 J-20 for our techs to deal with? Even if it works, is that worth it to shut somebody up? What if it doesn't work? What if, after all your troubles, spending years and billions of dollars developing something that the PLAAF didn't want/need while adding tremendous logistic complexity, he just says that these engines are sub-par and a poor stand-in for Russian engines, placed there only for national pride? Then what will you do? Make public the blueprints to prove to him that the quality is good? LOL

You sound very young, easily angered and manipulated by your adversaries. Good thing cooler minds make the decisions in China.

You exaggerated on that regarding the cost of setting up WS10x production line.

anyway, a least, he will have couple years of enjoyment of spreading Falsehoodness.

Oh no, he'll have the rest of his life to do so because falsehoods can always be spread.

I exaggerate the cost of integrating WS-10 into J-20? Really? Do you realize that you need new air-frames are needed for testing a new engine, right? The inlet shaping, internal load-out, engine area, (possibly the areas around the engine as they need to remain stealthy despite different heat output) all have to be re-optimized. These are hand-built unique frames, not production frame cost. How much do you reckon they cost? You can't make do with just 1 because you'll need to take what you learned from prototype 1 and build them into a second one. Maybe a third design if you learn even more. How many frames per step? (The more the faster the process.) Just the air frames are running up your costs into the 9 figures unless you wanna take 10 years conducting all your tests with 1 frame per step. If you wanna take that long, your engineering team costs will be high. And where will the WS-15 be by then? 10 years later, you'd have WS-15 running on J-20 making the whole WS-10 project completely pointless. So you'll need many air frames to get the job done quickly... cus you really wanna stick it to Majumdar LOL You'll need how many engineers? They all have to be paid for the duration of the project. They can't work on other projects that might actually be useful during this time. How long will this project last? J-10 1035 with WS-10 showed up how many years ago? And now we still don't see batch-production of J-10X with Taihang and J-10 is a much simpler design than J-20. Nightmare project...

It will take years, massive man-hours, and billions of dollars to do something that is not useful. I stand by that statement.

5 is gun port door. I pointed it out ages ago.

On the prototypes, they had a specially shaped panel behind this port. But on the production model, the panels are indistinguishable from regular panels. However, the opening/port is still there and in the exact same spot, so they almost certainly just changed the access panels to better optimise for stealth.

If they removed the gun, there would be no reason to keep the port.

I don't think that's the gun port door. It makes no sense. Why would it be divided into 2 sections? Why would it be so far back? It seems pretty obvious to me that the gun door is on the right side beside the canard. There's clearly a single piece panel about the size of a gun that's of slightly different color and is only present on that side.

 

[Richard Santos]

No 5 being a gun port also makes no sense to me. It looks like some kind of vent. Perhaps it is a fume discharge port near the breach of the gun. It certainly is not a muzzle port.

I wonder if I have at last managed to find the gun on the J20.

On the above picture, about half way between the left (plane's prospective) canard and main wing, there is a little darker coloured rectangular blemish.

What is more interesting is that immediately behind that, you could just about make out the outline of a much larger rectangular panel which I estimate to be around 1.5-2m in length with what looks like saw tooth at the back end.

Looks like a gun port and access panel for the gun itself to anyone else?

Seeing is believing.

Go to the original cluster of posts and you can see other members also did a lot of detailed analysis which conclusively proves that's the gun port.

I read those, it was far from conclusive as those analyses were based on grainy, low-res photos unlike the high-res we have available the past few weeks. With the better photos, it appears much more likely that the gun is on the right side.

Where?

 

[dingyibvs]

Page 405 jobjed's pic shows it pretty well. Wherever it is, I think we should get to see it pretty soon, since the next big reveal will probably be weapons testing.

A) the place you are suggesting is part of the main landing gear bay, which is normally occupied by the MLG wheels. We had a lot of very detailed pictures of that area and the internal structure from the earliest protypes, before that set of doors started to automatically close when on the ground. There is zero evidence of any gun there.

B) have a look at the below head-on photo of a J20.

Now please tell me you can see the obvious problem with placing the gun where you are suggesting. Give you a hint, look at the canards.

Finally, if you insist on wanting to validate using HD pictures, take a real proper close look at the following.

Extremely detailed image of J-20's back.

Pay extra special attention to the panel behind the gun port, and see if you can spot anything usual about it compared to all the other panels.

Hint, look at riveting.
