It is not a case of whether I am happy or not. When you have to resort to discuss a subject in dumpling terms, you are seriously short on facts. The reason you are deficit on facts is because there is no product to discuss - period.

We had things to discuss, things that were short and sweet but which you obviously found salty. And it happened to appear on a tweet about the F-31. If you were not happy, why did you not report?

Zong-zhi is celebrated during the 5th lunar month for a reason. Dumpling is a sacrificial food item to prevent bad omen. Having to describe the J-31 in dumpling terms is scrapping the barrel on facts because as is there is no product to discuss.

Uhhhh... you know “zong-zi” were sacrificial food too. Ancient Chinese made “zong-zi” so that they could dump them into the river to prevent the fish from eating the body of their heroic poet. I don’t want to go into the details now...

Dumplings (jiao-zi), on the other hand, was invented by Zhang Zhongjing, the famous ancient Chinese doctor in the Hang dynasty. He invented dumpling to cure frost bitten ears. At least that’s the story I’ve heard. I’ve never heard of dumpling being sacrificial food.

You might be talking about bao-zi. The legend says the famed military commander Zhuge Liang made “bao-zi” to look like human heads for sacrificial purposes when he was told that he had to make human sacrifices to cross a river. He didn’t like the idea of killing someone just to cross a river. So he ordered his cooks to make these huge buns with meat fillings to throw into the river.

Since we just celebrated Zong-zi this month, the reference to dumplings mean sticky rice dumplings as opposed to the generic meaning of dumplings which has much broader meaning in Chinese society especially between Northern and Southern Chinese cuisine.
As to the origin of Zong-Zi, the version I am familiar with is the sacrificial version.

Btw, "zong" refers to the dumpling. "Zi" means festival. In essence we celebrate "Zong-Zi" and eat the "Zong".

All these discussions on Zong-zi should be moved to the Chinese culture thread.

First, I don't know how good F-22 really is and how good F-35 really is, and I don't want to get into this topic. But I do remember a report of last year regarding a mock fight btwn an F-22 and a Su-35 in Syria. The F-22 was allegedly radar-locked by the Su-35. Although the account is not verified by third party, I think it is quite possible because the Su-35 pilot applied a tactics that maximized Su-35's strength in the fight. In other wards, how good a weapon really is in a real war situation is not completely determined by the people who design and make it, but also determined by the people who use it. Back to the J-31 program, I think it is not only a "possible", but also a "must" that it must be able to fight and beat the F-35 when it is used by PLANAF. In general, I am not a believer of US weaponry superiority. I think Vietnam Air Force, which was trained by PLAAF during the Vietnam war, has more to say about USAF superiority in the air war in Northern Vietnam sky, if PLAAF's scores against USAF during the Korean war are not convincing.

Second, I do believe that Boeing knows more about "aerodynamics" than COMAC. But knowing aerodynamics is one thing, respecting it is another. And it is not related to your ability to walk. I don't believe COMAC the Toddle would keep upgrading engines on a fifty years old air-frame without going through due "aerodynamics" analysis. Anyone with rudimentary knowledge about aerodynamics would like to see the 737 go through a full spectrum aerodynamic analysis once new power plants, that were larger in size, more powerful in thrust, were used, but aerodynamics expert Boeing apparently disagreed. Would you fly on the 737 Max-8 after Boeing tells you its MCAS has be upgraded, thus it is airworthy?

Indeed, lets get back to the J-31/FC-31 program, the program is an "in-house" proof of concept aircraft by Shenyang/AVIC, to date they have produced 2 flying "proof of concept" aircraft, an early aircraft, then a follow on aircraft with some aerodynamic/RCS reduction modifications, apparently using the Russian RD-93 engines that power the Mig-29... this very minimalist program has received minimal lip service from the PLAAF/PLANAF.

You my friend, are suggesting that such a minimalist program "must" be superior to the F-35 in order to be viable??? I'm simply reminding you that the nexus of the JSF program occurred in the early 90's, say around 1993, so its a well funded, (think Billions of Dollars), and well supported program with hundreds of operational aircraft, that is over 25 years old, and has a dozen or so international partners...

So lets leave your "straw man" arguments about an Su-35 vs an F-22 out of the FC-31 thread and stick to the facts... the FC-31 is a newborn, will it be further developed into a "real airplane", (Mr. Brumby's point by the way), or will AVIC use this experience to lead into a new proposal for PLAAF/PLANAF? No one here on SDF has any real knowledge of what comes next, I'm sure you're hopeful, I don't blame you, I would be too if I were looking at things from your perspective

I'm interested because its a beautiful little airplane, could it look any more like a LockMart bird?? lets be honest here, its going to take China just as much engineering and money to bring the FC-31/J-35 into existence, as it took the US to bring the F-35 to its current state of production.... that my friend is the reality facing China....

So the only part that I actually agree with you on is that one cannot use the existence of a design to argue its superiority over a rival. That said, he's clearly not referring to the current rejected prototype; he's talking about the J-35 that they are supposedly working on now fitted with WS-19 engines. There no reason whatsoever that this aircraft should be inferior to F-35, although we are comparing an operational bird to something that hadn't even been built yet.

It's more like a stealth MiG-29 since that aircraft was the first dual vertical stabilizer jet and what the LockMart birds look like.

Let's be honest here: that makes no sense at all. Because the US spent an extremely extravagant amount of money to build this weird tri-version jet with awkward functions, that means that China, with late-comer advantage, will spend the same amount of money to get a much more straight-forward single version jet working? There's almost no chance of that, because the J-35 program is much less complicated in requirements (no vert take-off, no 3 versions, etc...), China can learn from US mistakes (both from public information and that many people say China hacked the F-35 data), and because Chinese research is traditionally more cost-effective than American research.

You're the wishful thinker here, there's really no program of record, but if China does build the FC-31/J-35?? its gonna cost a hell of a lot of money and time spent engineering in order to produce an aircraft with similar capabilities to an F-35, and you know that as well as I do! so when this wishful J-35 is flying with two WS-19s?? if it ever does, then you've started down the path to maybe, possibly, hopefully being on trac to F-35 type capability, but you're nowhere near a STOVL fighter aircraft, so that's one more "pie in the sky" project for you....

Man & Brat, the notion of which is superior is based on subjectivity. There are no hard numbers of the performance and specifications of the FC-31 and its weapon systems. As much as both members' subjective reasoning is sound, it is a waste of time and bandwidth to debate on this issue.
