China’s Taihang engines have become a significant, large-scale presence in the military, making China the third country in the world that has mass deployment of domestically-produced high-thrust engines for military use, according to the Aviation Industry Corporation of China (AVIC) annual report.

AVIC's social responsibility report showed that the company is capable of independently conducting research and development on the next generation of high-thrust aerial engines, along with advanced drones such as Wing Loong, which have also been deployed in the military.

The People’s Liberation Army (PLA) Air Force has deployed no less than 400 Taihang engines in five air force regiments. Various types of fighter jets are equipped with the engine, including the J-11B and J-15 carrier-based fighter jets, reported China Science Communication, a news site under the Chinese Academy of Sciences. So far there have been no crashes due to engine failure among Taihang engine-equipped fighter jets, the news site also noted.

Some doubts have been voiced about the originality of the Taihang engine, as there are people who believe the Chinese-made engine is a copy of its Western counterparts. However, according to China Science Communication, the development of the Taihang engine was based on accumulated experience and technological advances gathered since 1978. The engine was also based partially on its predecessor, WS-6, which spent some 20 years in development.

Meanwhile, the engine also took inspiration from the control system of Russia's AL-31F aircraft turbofan engine, China Science Communication admitted, calling the Taihang engine a result of “independent development combined with technology from the Soviet Union and the U.S.”

“China has become the fourth country in the world to independently design and produce large transportation aircraft, as well as the third country to independently develop stealth fighter jets,” the AVIC report said, adding that China has advanced its air-to-air and air-to-ground missiles to the fourth generation.

This is actually pretty helpful for determining the number of J-11Bs and J-16s currently in service. We know for a fact that the first batch of J-11Bs entered service with AL-31s, so we'll count those out. There should be around 200 or fewer Sino-flankers currently in service since you always need some engines in reserve.

WS13E and WS15 in the pipeline... great going!

 

[Deino]

These engine looks like AL-31F engine.

This might be the reason for Your repeated claims that the J-20 uses WS-10.

If You look closely both engines are "similar" at best but especially the nozzle - most of all these more than characteristic two double dots in the middle of the pedals - are a clear sign to differ between both !

@Beast, please tag those Indian big mouths in here. Lol...

30 years past, and China is in a whole different level, but our Indian friends have yet to come up with new lines to attack their biggest enamy. They will continue this mumbling of "copy, paste, steal, hack......." for some time to come. Their weird sense of superiority and their frustration due to inability, do make a very interesting combination.

You don't apply this phrase to a country that is not important or does not have any impact on you.

Precisely because of this, the un-informed like to knock on Chinese products. When high-end Chinese products (DJI drones, Huawei smartphones, BYD buses and EV) become popular and respected in the West, the narrative will change.

In the sixties, it was fashionable to knock on Japanese products and deride them as cheap shoddy knockoffs.

In the eighties, it was the time to knock on the South Koreans and the Taiwanese products.

Now, it's the Chinese turn. (Actually, it is a badge of honor).

Six years ago, when HSR was mentioned, western media will bring out all the negatives such as it is not safe or won't be profitable, is an economic disaster, etc. etc.

Today, the narrative on China's HSR is mostly good. You can't really criticize the largest, fastest, longest, smoothest and most efficient HSR in the world, can you? It is generally acknowledged by experts that China's HSR is the best and most advanced in the world.

Just be patient guys and give it a few more years.

Without a proper engine, the J-31, China's second fifth-generation fighter designed by Shenyang Aircraft Corporation, will be unable to compete against Lockheed Martin's F-35.

The J-31 is currently equipped with two RD-93 engines imported from Russia. However, the Russian engine was designed for fourth-generation fighters such as the MiG-29. The thrust of two RD-93 combined cannot match a single F-135 engine on an F-35 fighter. When compared with the two F-119 engines of F-22 Raptors, the gap is even wider. In addition, the Russian-built engines has also shortened the range of the J-31.

Russian Klimov RD-93 Turbofan Engine


The J-31 is unable to fly long distances as its range is estimated at no more than 2,000km. This is only half the range of the J-11 fourth-generation fighter, a clone of the Russian Su-27 'Super Flanker'. Due to this major drawback the Chinese engineers had to make several modifications to the J-31 which in turn has caused the long delays towards its FOC. As per scant information available in the public domain due to China's obsession with secrecy, not much is known about the quantum of the traditional measures adopted by the Chinese to accord FOC for a high performance aircraft or whether China even follows the generally accepted principles for such a process.

Pratt & Whitney F135 Afterburning turbofan

Like India, China has also struggled with its Turbofan engine development efforts, though several engines have been developed over the past few decades, it is however not verifiable that a single engine has consistently powered an operational Chinese fighter jet. The Guizhou Aircraft Industry Corporation WS-13 Taishan developed exclusively for the FC-1 Xiaolong (or JF-17) was discarded midway because it lacked the expected performance and reliability.


Furthermore, it is claimed by the Chinese that the Shenyang WS-10 'Taihang' powers the J-11Bas and J-16s. Reportedly an improved version of WS-10 namely the WS-10A is being used on some J-10Bs. The WS-10 is alleged to be a clone of the CFM-56II itself based on the General Electric F101. In April 2009, Lin Zuoming, head of Aviation Industry Corporation of China (AVIC), reported that the engine's quality was unsatisfactory and its reliability was also poor. There have been a spate of accidents of fighters using these engines and such incidents have rarely been reported either in the domestic or international media.


During the last Zhuhai Airshow in 2012, the development of a new engine was announced by the Aviation Industry Corporation of China. The thrust of this new engine is estimated to be a 9,500 kilogram-force, which is more powerful than the RD-93 which can achieve only 8,300 kgF.


Finally, it can only be a subject of speculation whether the Chinese develop a high performance and reliable turbofan engine to power their fighter jets.

Chinese website mil.163.com says in its report today that China’s fighter jet engine producer Liyang Company sent a public message on July 1 on the successful first flight of an aircraft installed with a certain type of engine the company has developed.

The company’s great excitement at the success makes the website speculate that it was the test flight of a J-31 installed with new WS-13E engines that are improved version of WS-13 with greater thrust.

The aircraft took off at 9:53 am and landed at 10:01 am along designated route and did the climbing and flight according to schedule. During the 7 minutes 33 seconds flight, all the parameters of the engine remain normal and the engine worked stably.

According to the report, in 2012 China developed FWS-13 on the basis of Russian RD-93 to increase its thrust with augmentation to about 8,500 kg. The engine was successfully tested on a J-31, but the thrust is still not enough.

On April 22, 2016, Liyang’s holding company announced that it is investing 961 million yuan (US$171 million) in Liyang to build a production line of third-generation medium thrust aircraft engines including WS-13E with reduced weight and increased augmented thrust.

The report bares the secret data of improved WS-13. It says that its weight will be reduced from 1,135 kg to 1,050 kg but its maximum augmented thrust will be increased from about 8,700 kg to more than 9,000 kg to raise its thrust-to-weight ratio to 8.8.
