Could you please translate or give at least a summary?? Thanks.

Deino, I think it should be part of the forum rules that if you upload something in Chinese, you should at least give a short brief in english.

"More important than the upcoming carrier based AEWC itself, it is its WJ-10 engine, the first fully indigenously developed 5000 Hp class Turbo-Prop aero-engine, that could be in turn used to upgrade Y-8 and Y-9 transporters currently in active service, or used on new generation of median weight transporters, though it may not be the most advanced turbo-prop nor the most powerful one like NK-12".

Is there any word about a successor to the WZ-10? The T700 (most advanced variant ~1500kW) is going to be replaced with the T901 (~2200kW) beginning in 2024. That's the plan but whenever the US military announces anything, add years of delays.

it doesn't make sense to blame AL31 engine, it serves as stopgap for our fighters until WS10 engines get matured.

Fire Xie once and for all, and find somebody more capable. They spent 20 years making a copy of R-79, and who knows how much money, and still no engine in production... Tan Ruisong should also be asked where all that money went.

Chinese aerospace companies were and are a complete facepalm in their current condition.

Naval industry was whacked good in Zhu's years, and is now more or less globally competitive. Chinese frigates are selling like hot cookies. But there were not enough Zhus left for our aerospace industry.

He(the original OP in Chinese) made a mistake, the WJ-10 is NOT 5000 HP, it's 5000 KW.

Safran and AECC strengthen industrial cooperation on WZ16 engine

Remy Bertrand - Safran

6 November 2019, Beijing

Safran and Aero Engine Corporation of China (AECC) have signed a memorandum of agreement to strengthen their industrial cooperation on the WZ16 French-Chinese helicopter engine. This agreement was signed in Beijing by Alexandre Ziegler, Safran Senior Executive Vice President, International and Public Affairs, and AECC Chairman Cao Jianguo, during French President Emmanuel Macron's State Visit to China.

The WZ16 is jointly developed and built by Safran Helicopter Engines and AECC. Certification by the Civil Aviation Administration of China (CAAC) was announced on 10 October 2019. The engine is installed in the AVIC AC352 helicopter.

Through this memorandum of agreement, Safran Helicopter Engines and AECC agree to:

• Study opportunity for a joint venture in China to support and maintain in-service WZ16.
• Prepare and launch production ramp-up of WZ16 to deliver a first order of 120 engines and discuss opportunity for 100 additional units.
• Discuss new applications for WZ16, including turboprop variant for fixed-wing aircraft.

Alexandre Ziegler says that "the WZ16 partnership between Safran and AECC is already a success as the first jointly-developed aero-engine to be entirely certified by Chinese authorities. This new agreement is an opportunity to enlarge our partnership, especially as we prepare for certification and entry-into-service".

Also known as the Ardiden 3C, the WZ16 is a new-generation turboshaft in the 1,700-2,000 shp range. The Ardiden 3C was certified by EASA in April 2018.

The AC352's maiden flight took place on December 2016 and certification is planned for 2021.

Oh, btw, Good news !!!

@Deino @beijingwalker @LKJ86 Confirm it kindly !!

China has acquired Ukrainian Aero Engine Giant “Motor Sich Aero Engines”.

China was previously a stakeholder in the company. This acquisition will result in getting more assistance and required expertise to deploy even more advanced engines.

I googled it & found absolutely no news about this alleged news of China aquiring Motor Sich, they are only a stake holder apparently, so take this news of the takeover with 100 thousand tonnes of salt.

China Is Building More Powerful Jet Engines, And Is Selling Tech

China's air force could be about to get a big boost.
by Eugene K. Chow
Key point: China is quickly becoming an elite player in the Jet Age.

Chinese engineering has become so advanced that German jet engines could soon get a major boost from China.
Officials in China have begun talks to sell sophisticated aerospace technology and manufacturing equipment to Germany for the production of high-performance jet engines.

As China moves to rapidly build its commercial and military aviation industry, the nation has made significant engineering breakthroughs, most notably in turbine blades, which convert the heat from fuel combustion into thrust. Turbine blades are one of the most critical components of an airplane, determining a jet engine’s safety, power and endurance.

Engineers in China have developed new processes that can make lighter and stronger blades using a hollow structure as well as single-crystal alloys that can withstand high temperatures and a special coating to facilitate cooling. These advances mean Chinese-made turbine blades are able to withstand temperatures several hundred degrees Celsius higher than the melting point of metallic alloys.
These advances are at the center of a possible sale to Germany along with manufacturing equipment that uses lasers to drill ultra-fine holes in turbine blades to keep blades cool by increasing air flow.

“Our machine has outperformed [Germany’s] on some benchmarks,” an anonymous source involved in the negotiations told the South China Morning Post. “The Germans have seen and grown interested in our technology.”

Discussions for the sale are still in the early stages, but even the possibility of an agreement with Germany, which created the world’s first production-ready jet engine and has long been revered for its design and manufacturing prowess, is a major victory for China as it seeks to shift its reputation away from cheaply made knockoffs to high-end innovation.

Aerospace is one of the key sectors of the “Made In China 2025” initiative, which calls for massive government investment to create thriving self-sufficient domestic industries. But long before the initiative was announced, China has been hard at work developing domestically-produced military aircraft.

In 2011, China stunned the world with the J-20, the nation’s first stealth fighter meant to rival America’s F-22 Raptor. With the J-20, China became only the second nation after the United States with a tactical stealth jet in service.

Just three years later, China unveiled the J-31 stealth multirole fighter jet, which looks remarkably like the American-made F-35 Joint Strike Fighter. Analysts believe the Chinese built the J-31 using stolen F-35 blueprints.

China’s fifth-generation fighters currently rely on Russian engines, but recent breakthroughs have given the nation the ability to manufacture their own. In September, images revealed China had built a stealth engine for the J-20 equipped with serrated afterburner nozzles and interior flaps to help minimize its radar signature.

As China turns its attention to commercial airliners, it is only a matter of time before it begins to produce jet engines for commercial use.

In China’s rapid rise, it has previously turned to German aerospace companies to gain intellectual property and industrial know-how. In 2013, China acquired Germany’s Thielert Aircraft Engines after it filed for bankruptcy. The agreement included Thielert’s technology as well as their manufacturing facilities and equipment.

More recently, China has set its sights on purchasing Cotesa, an innovative German aerospace manufacturer that supplies parts for Airbus and Boeing. But the deal is currently on hold pending a review by the German government under new rules that grant the state more authority to block foreign takeovers.

The rules were passed in the midst of growing concerns of Chinese companies acquiring German and other EU companies operating in sensitive industries like aerospace, robotics and computer chips.

China’s plan to supply Germany with jet engine turbine blade technology is likely to face similar hurdles as Germany partners with Pratt & Whitney, General Electric and other American engine manufacturers. Even if German authorities approve the deal, the sale could still be blocked by the U.S. government which considers jet engine manufacturers as strategic domestic companies.

Regardless of whether this deal succeeds or not, it is apparent that China is quickly becoming an elite player in the Jet Age.
