Exciting Times for Chinese Aircraft Engines!

[SexyChineseLady]

More from Liu Daxiang's keynote speech:

Key to the chart is the "single technical verification" stage. This is where specific technology of the new project such as the WS-15 is verified on an existing engine such as the WS-10.

On the top of the slide, we see that the fan and compressor blades are verified on an existing engine WS-10. This means after verification of the specific piece for the WS-15, this new tech is put into the production line of WS-10 to work out the manufacturing process and improving the WS-10 as well.

The bottom of the slide shows other sections being verified with another existing engine which looks like a WS-13.

The middle of the charts shows the new tech after verification being integrated into the new core and then forked into various projects including the main project of the new gen engine but also a civilian version and other possible power plants termed "unconventional power" here.

This is not just for the WS-15 but a template for all engine projects going forward. New technology are expected to be verified on existing engines and to improve them and the current production processes as well.

This is an industry wide approach. You do not have to wait for the new engine to begin benefiting from the new technology and you do not need to verify new technology in a lab but on existing engines and production lines.

J-20 test/prototype numbered 2012 is rumored to have flown with WS-15!

 

[SexyChineseLady]

Official PAF placard on the J-10CE has the engine at 32000 lbs of thrust or 143 kN (the AL-31FN and AL-31FN series 3 that powered older J-10s were 125 kN and 135 kN respectively):

The engines used in the J-10, J-11 and J-20 (J-16 used WS-10B only) -- progression went from 122kN of AL-31F to 132/135kN of WS-10A to 140/145kN of WS-10B and finally 145/147kN of WS-10C (WS-15 would be ~ 180kN):

Interesting comparison between the Izdeliye 30 (SU-57) and the WS-10C(J-20):

Wait item 30 has not integrated with su-57 until now
I guess

WS-20s are becoming more common place. With hundreds (reported up to 1000) of Y-20s projected and its enormous possibilties in the civilian realm, the WS-20 might be the most consequential Chinese turbofan of all times.

But we can't say this yet because China also has the CJ1000/2000/500 family that might actually take that title of most consequential Chinese turbofan with the projected 3000 plus airframes of the C919, CR929 and ARJ-21 in the coming two decades!

The state of China's aero engine industry is incredible and incredibly exciting to watch!!!

 

[SexyChineseLady]

WS-10 for everything!

 

[SexyChineseLady]

Rumors of CJ1000 intended for the C919 is nearing first flight.

[SexyChineseLady]

The CJ1000A was supposedly mounted on a Y-20!

This is huge news. The requirements on endurance and reliability for civil turbfans are many times greater than that for military engines. Once this gets on the C919 formally it will create a sea-change in China's engine industry and also global aviation!

There are exactly four companies GE, SAFRAN (through CFM), RR and PW that can power civil airliners in the thousands (in China as well as the rest of the world.)

China will need thousands from the CJ-1000/2000/500 familiy to power over 3000 C919, ARJ-21 and CR-929 in coming two decades.

The CJ-1000's larger younger brother CJ-2000:

China's medium class engines -- WS-13, WS-21 and WS-19.

Seems like WS-21 is officially a separate engine type now. Many originally assumed it was a variant of the WS-13. Will need to reflect in my list!

Manned aircraft turbofan projects:

Engine	Latest Variant	Top Thrust (all variants)	Status
WS-10	WS-10C	155 kN	Production: J-10C, J-11BG, J-15, J-20A
WS-13	WS-13E	100 kN	Production Line ready: JF-17 test, FC-31 prototype,J-35 prototype
WS-21	?	~100kN	?
WS-15	--	180 kN	J-20 test
WS-19	--	110 kN	Il-76 flight testbed
WS-11	--	17 kN	Production: JL-11 (K-8 variant)
WS-17	--	49 kN	L-15 test
WS-18	--	120 kN	Production: Y-20, H-6 variants
WS-20	--	160 kN	Production: Y-20B
CJ1000	--	196 kN	Il-76 flight testbed
CJ2000	--	340 kN	core successfully ignited

WS-19

Mission/Strategy statement of ACAE (AECC Commercial Aircraft Engines) that produces commercial turbofans:

http://www.acae.com.cn/portal/About/Index_1_3.aspx

The three main projects are:

CJ1000A for narrow bodies (C919)
CJ2000A for wide bodies (CR929)
CJ500 for regionals (ARJ-21)

A J-10B re-engined with a WS-10B. The significance is the J-10B batches were the among last Chinese fighters to have AL-31s so their engines would have been fairly new. It seems the WS-10 engine is not only very good but also highly available that they would be re-engining J-10s and J-15s while J-16s and J-20As are being massed produced in huge numbers!

The photo comes from this one of of the 170th Air Brigade at Jiugucheng (also known as the 1st Flight Training Regiment.)

The J-10B is next to a J-10C which is next to a J-10S!

Remembering the WS-8 civilian engine. It was on the edge of success before being cancelled aling with the Y-10 when China pivoted to all things Western in the 1980s:

WS8 Engine

www.globalsecurity.org

The WS8 was a front-fan, axial flow, two spool turbofan engine with a short bypass duct. The take-off thrust was 80 kN (8,165 kgf), and it was developed for the Y-10 passenger aeroplane.

This engine was first developed by CEF in 1970. In September 1973, the task was transferred to the Shanghai Aeroengine Factory (SAF), which was built in the early 1970s. The work proceeded quickly under the support and assistance from all departments concerned. In June 1975, the 1st engine was released for test. Up to 1982, there were 8 engines on test: one finished 1,000 hours' endurance test, one completed 150 hours' airworthiness certification test, one was installed on aircraft for 8 takeoffs and nearly 22 hours proof flight tests. The results proved that the engine worked steadily, its performance was good, and it met the design requirements.

WOW! Two huge stories in one photo!!!

1) There is Y-20 flying testbed!!!

2) The engine being tested is a CJ1000 intended for C919!!!
