CCTV7:J-10B (图解军事纪实1220公开报道歼10B部队)

It is just the Chinese why to tell normal people in South Koren (the professionals knew it long time ago) that If you put THAAD near us, we will put J-10B near you.

I think this may be the place...

Notice these characteristics in the AL-31FN.

Double layer arrangement of the petals.

Gaps and spacing between the petals.

All missing in the pictures below.

Oh no... Not again.

So what's your point ??? Another secret Ws-24??? ... Or simply a too blurred image?

At least 53 J-10B and 50 J-10C have been produced. Where is the follow-up order for the AL-31FN Series 3? What about the hundreds of older J-10 that have been in production since 2002? They don't need replacement engines after over a decade?

Oh no... Not again.

really funny but why not they have money so yes they can do it.

Again .. What do you want to prove?

 

[j20blackdragon]

Again .. What do you want to prove?

Let me list out the total verifiable AL-31FN purchases.

2002-2004: 54 AL-31FN

2005: 100 AL-31FN

2007: 100 AL-31FN

2009: 122 AL-31FN

2011: 123 AL-31FN Series 3

499 total engines.

Even if I use very conservative estimates, at least 430+ J-10 have been produced so far since 2002.

That is not enough engines for the total aircraft.

Spare engines are needed for bird-strike, FOD, and other types of engine failures.

Older aircraft will require engine replacement after a certain number of flight hours. You can't overhaul the same engine forever.

Still no answer ! So what do you want to assume ??? Reall a secret WS-27 or what should that be per your idea?

J-10C used WS-10x domestic made high thrust engine instead of many assume AL-31FN russian engine. Mine assumption of J-10C enter service with high thrust domestic engine is correct.

The recent interview of李应红, 空军“飞机推进技术”高新技术中心主任-Director of PLA Air Force aircraft propulsion technology center, on the <<Ordnance Knowledge>>201612 editon confirmed that the latest J-10 modified model were quipped with WS-10s.

Buta again. This image you used show thal last two batch 01 aircrafts, none of any operational j-10 uses so far a WS-10 ... Snd you are mixing again J-10A, AY and B all with AL-31 nozzles.

And that engine image in that Chinese report is also an AL-31 - even worse an AL-31F with the gear box on top - ... So you really pretend these are WS-10 ???

 

[3jiL]

- Why batch 2 of j-10B(or C) no have MAW, May batch 2 built for PLANAF or cheaper version of B Verizon?
- Is 1035 prototype that use WS-10, crashed ?

I want to do some flight hours and engine life math with you.

PLAAF Su-27SK received 250 flight hours per year.
http://china-defense.blogspot.com/2009/04/decommission-of-plaafs-su-27-has.html

First contract for a batch of 24 Su-27 was signed on June 14, 1990. The original Su-27 airframe had a service life of 5000 hours. It was decommission in 2009 after 19 years of service.

5000 hours / 19 years = 263 hours per year.

I'm willing to round this down to 250 hours per year for easy calculation.

Two pilots were assigned to each aircraft, which means each pilot received 125 hours per year. But the airframe and engines received 250 hours per year. Keep in mind these hours were achieved throughout the 1990s and early 2000s when China was a much poorer country.

AL-31FN Series 3 TBO is 750 hours according to Salut.
http://www.salut.ru/ViewTopic.php?Id=2325

That means the older AL-31FN was less than that. I'm willing to be generous and give the older AL-31FN a TBO of 500 hours and service life of 1500 hours, but it could be less. The entire 1500 hour service life is used up in 6 years assuming 250 flight hours a year.

According to huitong, around 100 J-10 were produced by 2006.

Around 100 may have been produced by 2006 (01-03 batch, S/N 50x5x, 10x4x, 10x3x, 10x2x, 20x0x, 73x5x).
http://chinese-military-aviation.blogspot.com/p/fighters-ii.html

The aircraft above are over a decade old. All J-10s older than 6 years are likely to have received at least one engine replacement already.

Do you understand why I say 499 engines isn't enough? Can anyone prove China purchased more than 499 AL-31FN from Russia? Give me proof.
