Whether the J 10 engine uses a Russian made AL31FN or a domestic WS10A

Now it is still dominated by Russian-made engines, and the main domestic WS10A is still being improved... WS10A is to replace AL31FN, and it is still being imported, which means that the same type of domestic engine still does not meet the use requirements. . .

At present, the double-engine J-11B has begun to be equipped with WS10A, and the probability of the main two engines failing at the same time is still relatively low, while the single-engine J-10 is still quite risky to be equipped with a new engine that has not been tested for a long time.

In the future, it will be fully verified that the WS10A meets the requirements, and the J-10 will definitely be replaced with the WS10A.

When the J-10 test flight was installed, it was equipped with a Russian AL31, and the J-10A was equipped with an AL31FN

The J-10B is in the research and development stage and is equipped with a domestic WS10A; After service, it is also used with WS10A

At this stage, a large number of troops are equipped with J-10A, that is, AL31FN;

At present, it is still dominated by Russian-made engines, and the Qinling engine developed by China itself still has insufficient thrust and needs to be strengthened. It is possible that in recent years, with the deepening of materials science and dynamics research, we have developed new engines, but they have been kept in high secrecy.

China's completely domestically produced 3-and-a-half-generation aircraft is quite good and very powerful The J-10 is a single J-10 developed by China, which is a multi-purpose fighter, and this is the first time that the J-10 base has been made public to the public. Captain 16

The WS10 is said to be overhauled for 700 hours and has a full life of 1,500 hours.

There are many versions of the Russian AL31F, and the life span of different versions is different. Less than 300 900 hours or so (the least on the Internet there is also a version of only more than 20 hours, I don't know if it is a zero or a technical verification machine?) ), more than 2000 hours (all claimed by Russia).

The 117S on the Su35 (it is said that the 117S used now should also be an improved version of the AL31F, not the 117S of the Rurika Saturn) is said to have a lifespan of 4000 hours.

Compared with WS10 and AL31F, it is currently accepted that the acceleration performance is a little worse, and the starting speed is also a little slower (high-altitude parking and then starting, the height requirements are higher than AL31F, but it has been improved now, and it will be better than just coming out). The second is that the reliability is a little worse, for example, the surge problem has not been solved well, and it was said that it was solved for a while, and then it was said that it was not completely solved.

However, these are also uploaded on the Internet, and it is estimated that not many people know the specific situation. In short, the WS10 is now constantly improving, and it is hoped that we will see a more technologically mature domestic turbofan engine in the near future.

The current WS10 has reached 3000 hours of overhaul life.

The domestic life-enhancing transformation of AL31 is higher than that of Russia's own use.
