I think This One is the TV-command terminal guidance head for YJ63

That’s a DaMn*d a lot!! :diablo:

So again, Your saying let people believe in that the Turbofan engine design and manufacturing is a simple “copycat” job. your production depends on the products for that production is “availble” in the market or not. You buy the “blade” in the market as “dual use product”, then the 2nd day you ” sure ” can produce it at home.

Of course, for China, a new member of the exclusive turbofan engine club, the best way to catch up is to follow the mature and proven technologies. RE sometimes is the way to achieve that. To do a RE, you have to do 2 things, 1st, you need the physical product sample you want to RE, 2nd, you need your own effort to make your “copied” product up to the standard of the original. yo try to emphasis here is the 1st part is more important for a Re job done. However, as I and some othe mumber posted here already point out, the 2nd part, how to make your own REed product up to the standard is much more difficult and important than your” availablity of original product sample” theory. My previous post already said: “Most other countries got better access to those civil engines and relevant technologies as well as much wider choice of assistances from the well established western countries in designing such engines. However, why there are not so many F110-alikes everywhere? Because the complexity of making a turbofan engine still determines finally.”

Your words are quite “confusion” at 1st place, never mind, let me look into what the 2nd possible meaning of your post so no argue at the end:

If you say the WS10A going to use all ” imported” blades via the “dual use prodcut” channel, ( because China got enough CFM56s to claim the demand 😀 ). Then, you can ignore what I posted for the progress what China achieved in the area of Avaition materials technologies. but just use simple logic to judge yourself.

Just ask some simple questions to yourself:

1st: How many WS10A going to be produced?

As a comparison, the demand for RD93 grade engine for FC-1 fighter alone is 500-600 as estimated by Russians. As the main stream Engine for PLAAF, Do you think the demand of WS10A is below 1000 units in future? Then again how many CFM56s does China have? can you import so many blades as replacement for “spoilt parts” of those CFM56s to fullfil the need of WS10A productions?

2nd: Is the design of the CFM56 blades are the the same as those of WS10A? my references and what other ppl already posted show there’s different.

You know who is viewing the WS10A blades

The CFM core engine delivers the technical layout. Even the blades for that core engine can be bought as replacement parts and those are high-tech parts too. You can trade the high lifetime of such blades against performance.

As a matter of fact, China “borrowed” only 2 unit of CFM56 from US for evaluation during honeymoon period in 1980s when then USSR is their main concern. The 2 units of CFM56 were supposed to “return” to US once the evaluation period was over.
However, 1 unit of the CFM56 was reported destroyed during a fire and never returned to US. So do you think US will supply the needed blades to Chinese? And China is stupid enough to rely on such “spare parts”? and don’t make such blades by themselves?

Nothing is wrong for China to start a Military grade turbofan from a civil engine. Most other countries got better access to those civil engines and relevant technologies as well as much wider choice of assistances from the well established western countries in designing such engines. However, why there are not so many F110-alikes everywhere? Because the complexity of making a turbofan engine still determines finally.

Wow, Great picture , And the following ships will be built in Singapore as well.

BTW, is the 2 picutres showing the FFG doing sea trial or on the way back home( Singapore)?

The information is openly available on the AVIC1’s official website( Of course it won’t call the engine directly as WS-10A)

I think the initial AMT finished (450hrs Duration Test) at end of last month. No606 Institute tries to finalize the design by the end of this year. Maybe small batch production already started after the 450hrs Duration test(IMO). Formal production likely at beginning of the next year.

Oh, Game over for SAC J8…
