Familiar in the sense that it could be just an AL-31? or WS-13 (based on RD-93)? If not, what it could be?

The type of petals used on an jet engine doesn't always indicate the type of engine used. I'm still figuring out how the bands come about.

i took a look at that one. Just seems like some dude posting what he saw on QQ. Doesn't seem to be from any standard big shrimp that we know are good sources.

One thing we knwo for certain is that J-16 prototyes are all using WS-10A and WS-10B. J-15 will be using WS-10B soon next year with FADEC.


FADEC is more important than just increase of thrust because it allows much smoother and rapid acceleation, also the improved WS-10B will be more realiable and more dureable (around 2500 hours compare with 1800 of WS-10A and 1500 of AL-31FN).

WS-10B will have:

135 KN of thrust that is 10KN more that the AL-31FN and WS-10A.
FADEC.
Better realiability compareable with AL-31FN.
1000 hours of Mid-life overhaul, and 2500 total.

These features will make WS-10B compareable to the AL-31FM1.

Over Chao Da, they are saying that more than 24 J-10B has been produced without engine, and I think that they are all waiting for WS-10B, since China has a huge stock pile of AL-31FN (around 180 AL-31FN).

J-20 (2003) is also waiting for a new engine, might be AL-31FM1 or WS-10B.

Let's wait and see what happen.

I am getting more and more confident of WS-10, even though the Su-35 purchase might be true, and China gets 117S, it will further help WS-10, because the 3D TVC technology will also be added to later WS-10 upgrade.

　中新网北京6月20日电 (记者 孙自法)中国科学院最新出炉的一份战略研究报告披露，未来10年，中国有望研制成功新原理航空发动机样机，这将改变中国航空发动机研制落后的状况。

　　由中科院院长白春礼院士领衔、200多位专家历时1年多深入研究推出的《科技发展新态势与面向2020年的战略选择》研究报告20日下午在北京发布。该报告预计未来10年中国可能发生19项重大科技突破，其中之一就是“新原理航空发动机样机将有望研制成功”。

　　推重比是航空发动机最重要的技术性能指标，中国正在研制的WS10发动机和WS15发动机推重比分别为8和10左右，属国际上第三代和第四代发动机。《科技发展新态势与面向2020年的战略选择》报告透露，基于自主创新的新型增压原理，通过系统发展压缩系统气动、结构设计方法，构建新的高推重比航空发动机技术体系，中国将很有可能研制出新原理航空发动机，在国际上首次实现推重比15以上样机的演示实验，为高速巡航导弹、高机动性能战斗机、临近空间飞行器等提供高性能动力保障。
China academy of science report that for the next 10 year,China able to overcome all technical difficulties in designing and building jet engine.
while the current generation Chinese make engine such as ws-10 and ws-15 .which has T;W ratio 8 and 10 belong 3 and 4 gen. jet engine.while othercountries already pushing for a 15 to 1 T:W engine,China may also achive similar goal.

We'll believe it when we see it.

China's top science advisers have listed 19 projects as the research priorities of the next decade. They include quantum telecommunications and a high-performance jet engine that could drastically improve the capacity of its indigenous fighter jets.

The report written by more than 200 experts at the Chinese Academy of Sciences paints an ambitious road map for the nation's science development, as Beijing tries to break the dominance of Western countries. These top-priority projects include military, space, new materials, energy and agriculture.

The most eye-catching one is a new jet engine that promises to deliver thrust equivalent to 15 times its own weight. The thrust-to-weight ratio is a key indicator to measure a jet engine's performance. In comparison, the Pratt & Whitney F119 turbofan engine used in the United States' F-22 raptor fighter has a thrust-to-weight ratio of eight and is widely considered one of the most advanced jet engines today.

Engine technology is widely known as the weakest link in China's aviation sector. The country to date has had to rely heavily on foreign imports, particularly from Russia, to power its fighter jets. The new engine mentioned in the CAS report surprised many people and caused much scepticism.

Professor Tao Zhi , an expert in jet engines at Beihang University and chief scientist of several military jet engine research projects, confirmed the project but said he was surprised the CAS had made it public. "It is a top-secret project. Anything about it is hush-hush," he said.

Tao said the US had been working on a similar project. China had to come up with something "fundamentally different" if it were to catch up with the US, which led China in the field by at least a generation. "It is a very sensitive topic. Any discussion about it could be considered as leaking national secrets," Tao said.

The CAS report said the engine would use a totally new boosting method. The engine would not only be installed on high-performance jet fighters but high-speed cruise missiles and near-space vehicles.

The report also projected that China would build the world's first quantum communication network. With the launch of a quantum satellite in 2016, China would overcome the short-distance issue of existing quantum communication technology and achieve data transmission that could not be hacked by conventional methods.

But the CAS could be overoptimistic.

In 2003, the Ministry of Science and Technology released a similar, decade-long forecast on technological breakthroughs. The ministry report listed genetically modified food as one of the most promising sectors. But due to the lack of scientific education and protectionism in agriculture, genetically modified food on the mainland was still struggling with a negative public image and low acceptance that severely hindered the modernisation of agriculture.

report claim that WS-15 has 10:1 Thrust ratio,which is surprising.if they can delivery that kind of engine,surely they can technically produce jet engine that can rivalry M-88 or ej-200 rather old WS-13
