Exciting Times for Chinese Aircraft Engines!

[India Super Power]

To be honest, I have not heard Pakistan say the JF-17 is their own. It is always marketed as a joint venture.

The truth is China doesn't use the FC-1/JF-17 and is really able to market and export the FC-1 only because of Pakistan. Pakistan uses the plane and assembles it. Without that, few countries would buy a plane that the Chinese air force doesn't use.

In fact, China not longer has the lines to deliver the JF-17 so Pakistan provides capacity that China doesn't have (and can't have because CAC is stretched trying to delivery J-10s and J-20s.)

Also because of Pakistan and the JF-17, China's aviation industry has to work on a medium engine as a possible substitute. The PLAAF doesn't use a medium sized engine at all as they went with heavy AL-31/WS-10 for all their fighters.

But the Pakistani connection allowed China to work on the WS-13 and later the WS-19. This turned out to be very fortunate because when the Chinese Navy started looking at a new stealth fighter they now have a medium sized engine for their new fighter. Without WS-13 and FC-31, PLAN might have gone for a naval J-20 instead of J-35.

Anyways, China has now gone full tilt into medium engines and medium-engined aircraft like the FC-31(that they are now fully backing for export.) It is a very good thing that WS-13 line is now operational for mass production because there are many more projects around the world like TFX requiring a medium engine than a heavy one.

Are bhailog ise malum nahi hai ki porki JF-17 ko indigenous bulate hai

“As long as they have to depend on Russian or stolen American/European technology to power fighter aircraft, their ability to build and maintain their fighters in operational status is under threat,” he says. “So if they are to become the military equals of outside forces, they have to be able to create engines. And engines are the real limiting factor in indigenous fighter development. There are only a few companies worldwide who have the ability to design and build an all-new, state-of-the-art engine.”

Several fighter programmes illustrate the theme of indigenous fighters with foreign engines. The Saab Gripen, Korea Aerospace Industries (KAI) T-50, Hindustan Aeronautics Tejas, are all powered by a General Electric engine. KAI’s planned KFX will also be powered by the F414, as will New Delhi’s Advanced Medium Combat Aircraft (AMCA).

Beijing is pouring great resources into its own development work, but is not above stealing technology. It is understood that the core of the WS-10 is based on CFM International CFM56 technology that China obtained in the 1980s. In October 2018, an alleged Chinese intelligence officer was extradited to the USA to face criminal charges related to a scheme to steal trade secrets from leading US aviation companies, including GE Aviation. Court documents suggested the alleged theft targeted technology related to engine fan blades and "containment structures".

The requirement for Beijing to steal technology was highlighted as early as 2011 in a report from the Washington DC-based Institute for National Strategic Studies entitled Buy, Build, or Steal: China's Quest for Advanced Military Aviation Technologies. The report concluded that China would find it increasingly difficult to develop highly advanced aerospace technologies, and its traditional partner Russia is ever more wary of sharing technology owing to fear of intellectual property theft. This will force China to rely increasingly on espionage to obtain advanced capabilities.

Observers will also be watching Chinese firm Skyrizon’s effort to buy a majority stake in Ukrainian engine manufacturer Motor Sich, which produces turbofans and turboshafts. The potential deal is reportedly under review by the Ukrainian government, and is opposed by Washington DC. In May, the Washington Post reported that the company, which formerly relied on Russian aerospace work, sees few opportunities for its future outside of China.

Rupprecht adds that Beijing’s ultimate goal is to be completely “self-reliant in every aspect” of engine development and manufacturing.

“A good number of J-10s and J-11As, as well as their Xian Y-20s and H-6Ks, depend on Russian engines,” he says. “This is unacceptable for the longer term, especially if the political climate with Moscow were to change. Therefore they are placing great effort to develop new engines in different classes and establish a broad industrial base.”

Tokyo, New Delhi power up

The Asia-Pacific region's other great powers, Japan and India, also see the importance of advanced engine capabilities.

Tokyo was developing jet engines as long ago as the Second World War. A locally developed high-bypass-ratio turbofan, the IHI F7, powers the Kawasaki P-1 maritime patrol aircraft.

In June 2018, IHI delivered the experimental XF9-1 engine, which can produce 33,000lb-thrust (147kN) with afterburner, for laboratory research work. If Tokyo decides to advance its Future Fighter programme to replace the Mitsubishi F-2, the new twin-engined stealth fighter could be powered by descendants of the XF9-1.

Another Japanese engine, the IHI XF5-1, powered Tokyo's X-2 technology demonstrator.

ANALYSIS: The secret world of Chinese fighter engines

"A riddle, wrapped in a mystery, inside an enigma," is how Winston Churchill famously described Russia in 1939. The adage applies well, perhaps better, to Beijing's secretive efforts to develop military engines for its future fleet of advanced fighters. While there can be no dispute that engines...

WS-10 TVC!

 

[SexyChineseLady]

There are constant upgrades among the WS-10 engines with each batch so that even the variants have subvariants! For example, there is the WS-10B on J-10s and J-16s but the J-16 uses the WS-10 Series 3 and within the Series there are short and long petals.

Incremental changes and upgrades all the time. (You see this in Chinese components all the way to large assembled systems like warships too -- Type 052D to Type 052DL.)

For the record on the CJ1000 (for C919) and CJ2000 (for CR929):

Google translated (from Japanese):
The CJ-1000 engine, which will be equipped with the C919, uses a special titanium-aluminum alloy fan blade developed by the Metal Research Institute of the Chinese Academy of Sciences, and has twice the specific gravity of the conventional nickel-based alloy. The development of CJ-1000 is going well, and CJ-2000 is also being promoted.

The core engine of the CJ-2000 was successfully ignited for the first time on March 5, last year, achieving a maximum rotation of 100.6%.

CJ-1000

* In August, the third trial production machine was installed with a radio telemetry system in to prepare for installation on the Il-76 test platform of the Flight Test Institute.

* In September, CJ1000A completed the 5-hour limit thrust test on the ground, and the measured thrust was 14.5 tons, exceeding the original 14 tons expectation

* On December 22, CJ1000A completed the blade fly-off test.

* During the Zhuhai Air Show, the CJ1000A was exhibited in a 1:1 full-size model, and even the engine nacelle is already available, which shows that this engine is very well-completed and is expected to be similar to the mass-produced model.

* According to the engine model and exhibition board information displayed by Shangfa, the titanium alloy fan originally used in CJ1000A has been changed to resin-based composite fan blades, plus the nacelle is 5.7m long, 2.7m wide, and 2.7m high. The diameter of the fan is 1.95 meters, the thrust is 12913 ~ 13608kgf (12.913 tons ~ 13.608 tons).

* Precise thrust data shows that the prototype of CJ1000A has successfully completed several test runs, and it is expected that the flight platform test flight has begun. It is understood that the current LEAP-1C engine on the C919 passenger aircraft has a thrust of 12998kgf to 13,714kgf, which shows that China's CJ1000A has reached the level of LEAP-1C.

* According to the information disclosed by Jiangsu Xinyang Company, domestic composite fan blades will be used in CJ series large ducted engines, including CJ1000A engines. After replacing the composite fan blades, the CJ1000A has better performance and lower fuel consumption, which can further enhance the market competitiveness of the C919 passenger aircraft.

* According to previous optimistic estimates by COMAC, CJ1000A will complete the certification of airworthiness next year as soon as possible, and C919 can be installed as soon as 2023.

CJ-2000

* The CJ2000 is the second civil turbofan engine with a large bypass ratio independently developed by China after the CJ1000, with a thrust far exceeding the CJ1000A.

* Thanks to the technological breakthrough of CJ1000, the various nodes of CJ2000 are progressing rapidly, and the comparison shows that the overall progress is only about 1 year behind CJ1000's aviation development

* The progress of CJ2000 has entered the stage of verification machine, and CR929 will be installed in 2025 at the earliest.

* According to information disclosed by the Commercial Development Company, in March 2020 , the domestic CJ-2000 engine core engine C2XC-101 was successfully ignited and reached 100.6% speed in subsequent tests.

* In July 2020 , the CJ-2000AX verification machine was assembled.

* On August 12, 2020 , according to China Business News, China Aviation Development Shanghai Commercial Aviation Engine Manufacturing Co., Ltd. has launched the bidding work for the hardware configuration of the low-voltage component telemetry system of the CJ-2000AX verification machine, which means that the CJ-2000AX engine has entered the test-run stage of the demonstrator,

* The core parameters of this engine are in the promotional video of China Aviation Development at this air show. The CJ-2000 is a turbofan engine with a large bypass ratio. The diameter of the fan of the CJ2000 reaches 3 meters, which is much larger than the 1.95 meters of the CJ1000.

CJ-500

* The CJ500 is a turbofan engine with a thrust of 7 tons and a large bypass ratio. It is a domestic aviation engine supporting the domestic regional airliner ARJ-21.

* As the development of the CJ1000 project is coming to an end, the Yangtze River 500 has also begun model development.

* According to a source, although the project development started very late, due to the development experience of the CJ1000 engine, the development of the CJ500 is progressing very fast, and it only takes 3 years to successfully develop!

WS-15 Emei officially announced and interestingly it is mentioned as being use by both medium and heavy fighters.

Medium would mean a single-engine fighter. Maybe the J-10 can be upgraded or a new single-engine stealth design!

Taiwan says Chinese warplane crashed in disputed South China Sea

• Intelligence chiefs tell legislature that a Y-8 anti-submarine vessel came down in the disputed waters earlier this month
• Beijing has not confirmed the reports but the briefing says the PLA launched search and rescue operations under the guise of training drills

Taiwan’s intelligence authorities have said that a People’s Liberation Army warplane crashed in the disputed South China Sea earlier this month.
Soon after the accident, the PLA announced military drills near the suspected crash site, the island’s National Security Bureau told the legislature on Thursday, confirming earlier reports by a Vietnamese journalist.
The intelligence bureau chief delivered a report that said the crashed plane was a Shaanxi Y-8 anti-submarine warfare aircraft. He added that soon after the crash, the PLA announced navigation restrictions in the adjacent waters to carry out search and rescue operations in the name of “military training”.
It said the operations were conducted in the waters close to the disputed “nine-dash line”, which marks the maximum extent of China’s historical claims over the South China Sea.

Its claim over the waters and the islands within it – including the Paracels, Spratleys, Zhongsha and the Pratas – are disputed by several countries, including the Philippines and Vietnam.


The report said the PLA wanted to use the incident to “test the limits of the US and other South China Sea claimants” while the world was focused on the Russian invasion of Ukraine.
Asked to elaborate on the incident, bureau director Chen Ming-tong declined to give further details, saying the entire case involved sensitive intelligence issues.

Chen was invited to the legislature on Thursday along with other senior officials, including defence minister Chiu Kuo-cheng and Mainland Affairs Council vice-chairman Chiu Chui-cheng, to report on the cross-strait situation following the invasion of Ukraine.

Chen confirmed a Vietnamese journalist’s report that a Chinese military patrol plane had crashed off the coast of Vietnam.

On Sunday the journalist, Duan Dang, citing sources familiar with the matter, tweeted that the PLA Air Force had lost contact with a Y-8 maritime patrol aircraft as it flew over an area of water southwest of Sanya in China’s Hainan province on March 1.

He said China had launched a search-and-rescue operation and “concealed it with drills” between March 1 and 2.

China never acknowledged the incident but it did announce that it would carry out a week of military drills until March 15 in an area between its southern province of Hainan and Vietnam and warned shipping to stay away.

Meanwhile, defence minister Chiu said a conflict with the mainland would be a disaster for all sides regardless of the outcome.

“Nobody wants war,” Chiu told reporters before he attended Thursday’s legislature session, where he and other senior officials were questioned about the cross-strait situation following the Russian invasion of Ukraine.
Asked by reporters about the possibility of Beijing seizing the opportunity of the Ukrainian crisis to attack Taiwan, Chiu said such a possibility was slim given that the mainland is busy with its parliamentary sessions and the upcoming Communist Party congress.
He said no matter who won the war, it would be a “miserable victory” and so it was necessary for the mainland to “thoroughly think it over”.

Taiwan holds urban, aerial combat drills amid threats of invasion by mainland China
Beijing considers Taiwan part of its territory that must be brought under its control – by force if necessary.

It has ramped up pressure on the island by sending warplanes and staging war games near its coast to try to force President Tsai Ing-wen of the independence-leaning Democratic Progressive Party to accept the one-China principle.

[SexyChineseLady]

China's current workhorse turboprop is the WJ-6C (on the Y-12, Y-7 and Y-9.) It has 3200kW of power. AEP500 will be a big improvement!

But WJ-6C has been serving in a lot of roles. Turboprops are forgotten but important engines -- transport, MPA and AWACS for examples.

Yes, future is very bright with so many projects and the young people staffing them!

Seeing pictures here and there of a lot of these that we will see in the coming five years or so -- WS-19, CJ-1000, AEP500 -- and the aircraft they will power -- J-35, C919, MA-700 -- have very young teams!

WS-19 design team!

Yes, future is very bright with so many projects and the young people staffing them!

Not necessarily a good thing.
The golden age of an engineer should be between 30-50. The youngers lack experience and the older can't catch up with new knowledge. So, the best team should have the middle age engineers as their majority.
In the case of China, this phenomenon (young team) has been continuing for 30 years. This presents an issue: they are keeping lose their experienced engineers to private department.
