Like more stories of Chinese espionage attempts?
Yeah I believe that.

I think he meant that it’s more complicated than simply getting info to copy — it doesn’t really make sense seeing as they have HQ-9.

It said the espionage involved tech and maintenance documents — possibly to supplement insufficient russian cooperation on maitenance or what not, given previous chinese experience? Clearly china’s not trying to clone S-300 and the idea it’s for integrating with the rest of the system/maintaining existing batches is more logical.

I don’t see how S-400 is relevant here, though didn’t China partially fund that project or something?

listen we know you want to compare JH-7 to aircraft of a different generation..but let us not fool ourselves, the JH-7 is the same generation as the Jaguar, Mitsubishi F-1, Mirage F.1. It just came later because China was behind technologically, but now as you can see that while they may not be at the same level as the US, especially engines, that with the J-20, they reached parity with Russians.. at least in the fixed wing combat aircraft area.

Oh I think it’d be one generation after the likes of jaguar surely. Let’s not heighten this discussion on the respective country’s aerospace industries… We’ve all seen how bad that turns put

@JSR jh7 can carry up to four stand off weapons on four pylons, leaving two spare on each wing for sraam or other munitions, centerline for fuel tank and a dedicated space or a targeting pod… There is surely some substance in that..

You seem to have big issues with the claim about th PGM number dropped at that blue sword exercise — it was only a rumour, you could always ask for clarification if you have issues with it. Rather that than comparing SMT with jh7 rofl..

What happened to the colour of nozzles ?

Cloud cover.

It is true that a circular shape is a good reflector… if it is made reflective. I rather think they leave the sphere transparent (i.e. without the reflective gold layer or so), and goes for RAM treatment on the stuff inside instead. The glass sphere is an important part of the lens system, isn’t it? Then it can’t be faceted if they want to keep the optical properties

F-35’s EOTS, the superhornet proposal’s IRST and sniper pod are all faceted too.

Sure, but what have Russian Car industry to do with Aviation prospect?
Russia should do what they do best.
Pls do not derail the thread.

The state of the chinese industry in relation to its aviation industry is perfectly relevant to the PLAAF. Manufacturing, sub contractors, RD, money to invest and buy.
Replying to madrat’s comment about the chinese ability or inability to make ~100 high end engines per year, the strength of the overall chinese industry/economy and its overall trajectory will of course influence how long “quite some time” turns out to be.

How many WS-10s is shenyang liming producing a year anyway?

It seems every year the Russian fanboys have fewer and fewer things to gloat about.

Let them have their moment with their current engine manufacturing edge boasts, they have precious little else to be pleased about.

If anything, China should be amused that it’s advancement is getting the Russians so worked up. You don’t see them feeling this insecure around the Indians do you? :rolleyes:

C’mon plawolf, let’s not further this useless contest.

Problem now with WS-10 seems to be they can’t make enough of them.

We can keep splitting hairs and bargaining over centimetres all day, but the key point is that the tail fin trailing edges on the J-20 protude *significantly* less beyond the nozzles than the tail sting on the Flanker or the tail planes on the Raptor. The fact of the matter is, based on the J-7 (IMHO the most accurate reference, given the uncertainty surrounding the JF-17 and the extensive modifications on the J-10B compared to the -A) our best guess for the J-20’s length is 20.9m.

I do not understand, there was confusion over values for J-7s length as well, shouldn’t that invalidate it as much as j-10b and jf-17?
Besides a few pages back pinko gave a good estimate of j-20s length from a picture of j-10a (both aircraft taxiing at the same positioning) and I gave myown estimate with a picture of j-20 and it’s tug, knowing the tug’s length from the manufacturers website (link now broken) — both measurements gave ~20.5 m, closer to the 20m mark.
