Rongcheng, aircraft factory.

The WS-10 engine made its maiden flight in October, loaded on the Su-27.

Over the course of more than two months, several more test flights were carried out, and the flight time of the first WS-10 engine reached 300 hours.

And after the overhaul, it was found that even after 300 hours of flight, all parts of the engine were still working well.

It is expected that the working life can reach more than 1200 hours, and you must know that the working life of Damaojia's AL-31F engine is only 900 hours.

Because the WS-10 engine is in this world, it does not borrow too much from the technology of the AL-31, so it actually avoids some problems of the AL-31 itself.

The WS-10 engine was originally intended for use in the newly developed third-generation J-10 fighter.

The prototype of the J-10 is manufactured much faster than the development of the WS-10 engine.

The development and manufacturing of the first testing machine was almost completed a few years ago, but the development of the engine has been met with various obstacles.

This has not been able to complete the development and manufacturing of aircraft.

However, this year, the development progress of WS-10 has advanced by leaps and bounds, and in just a few months, many major problems that have plagued engine research and development have been solved.

The engine suddenly surpassed the AL-31F of the big hair family from the original Fira's unbearable state.

While many people were surprised, it also made the J-10 aircraft project team, which had been waiting for a domestic engine and was ready to switch to the AL-31F engine of Da Mao's family, happy.

After all, the WS-10 is almost exclusively customized for the J-10, and a lot of preparations have been made in all aspects.

Unlike the AL-31F engine, if the J-10 really wants to use this engine, then the aircraft will have to be modified in all aspects.

In this way, the J-10 will really make its first flight, and it is not known when it will be.

But fortunately, the development and manufacturing of WS-10 was successfully completed, and the J-10 fighter did not have to work so hard to adapt to the AL-31F engine of Da Maojia.

The first flight time of the J-10 fighter, as well as the subsequent service and installation time, can be greatly advanced.

This can greatly alleviate the current pressure on the Air Force, and you must know that the vast skies of the motherland are almost still guarded by the Jian-7 and Jian-8.

The dozens of Su-27 fighters imported from Da Mao's family can almost only be equipped with one aviation regiment, and they are regarded as treasures by those units equipped with Su-27 fighters.

It is too difficult to rely on these Su-27 fighters to guard the long border of thousands of kilometers of the motherland.

If the J-10 fighter is successfully developed and can be mass-produced, it will greatly improve the Air Force's ability to defend the country.

In the aircraft factory, Zhang Zhengjiang, the chief engineer of the WS-10 project, is communicating with Song Tianxing, the chief engineer of the J-10 project.

"Lao Zhang, you did a good job this time!"

Song Tianxing, who had a cute face, joked with Zhang Zhengjiang.

"I didn't expect you to solve so many problems in so many months."

"Awesome!"

In the face of Song Tianxing's praise, Zhang Zhengjiang was not proud, but very modest.

"The main work to solve the problem is to rely on the help of brother units, and it is difficult for us to solve so many problems so quickly on our own."

Song Tianxing was not very surprised by this answer, after all, he was very familiar with the members of the WS-10 project team and knew the abilities of the members of the WS-10 project team.

If they only rely on themselves to gnaw on these problems little by little, it will take three or four years to say the least.

But they solved it in a few months, and there must have been people from other units to help.

"Which unit?"

"Such a cow, in such a short time, I will solve the problem for you."

Song Tianxing couldn't help but ask.

"The materials laboratory of the Rocket Research Institute, their latest high-temperature materials, are very strong and solve the material problems that have plagued us for a long time."

Speaking of the reason here, Zhang Zhengjiang said with great emotion:

"And their high-temperature powder metallurgy process also seems to be advanced, with the parts manufactured almost entirely in a single crystal arrangement."

Song Tianxing was a little surprised at this time, after all, in terms of rockets, the Rocket Research Institute may be in the leading position in the country.

However, in terms of material R&D and manufacturing, the Rocket Research Institute can only be said to be unranked.

Hearing that they had made such significant progress in the materials really made Song Tianxing surprised.

"Didn't they just have an accident at the beginning of the year?"

"It's amazing to be relieved so quickly, and to get so many results!"

Zhang Zhengjiang is used to other people's thoughts, after all, things here are really outrageous.

"Don't talk about this, is there any difficulty in loading the WS-10 on the J-10?"

After chatting a little bit, Zhang Zhengjiang and Song Tianxing talked about business.

As the supporting engine of the J-10, the WS-10 itself was developed for it.

Loading the J-10 fighter is what Zhang Zhengjiang, as the chief engineer of the WS-10 engine, is most concerned about.

Seeing Zhang Zhengjiang's expression of resuming work, Song Tianxing became a little more serious, and took a summary of the various types of problems of the J-10 project team on the WS-10 installation before Zhang Zhengjiang came.

"At present, the installation problem is not particularly big, and our engineers have tried to install it before, and have carried out a certain degree of ground testing."

"It's just that there are some minor problems, and there are no major problems."

"Now we have almost solved these small problems."

"But you also know that the actual operation at high altitude is completely different from the situation on the ground."

"If you want to get real data, you have to do a test flight."

Zhang Zhengjiang is not particularly surprised by this, the test flight is a very important link in the entire design improvement process of the aircraft.

If you want to get real and detailed data, you have to rely on a large number of flight tests to get it.

"How is the readiness for the test flight, and when will the first flight take place?" Zhang Zhengjiang asked.

"It is now close to the end of the year, and the preparations are estimated to be completed before this year, and the time for the first flight may be after the New Year."

Although Song Tianxing also wants to carry out the first flight of the J-10 as soon as possible, the preparation progress is not very ideal, and there is definitely no hope before the year.

And at the end of the year, there were a lot of messy things, which involved a lot of everyone's energy, and we had to slow down the pace of preparation.

"How is the training of the first flight pilot, this flight is still very risky."

"The first batch of test pilots has completed all the training subjects and will be able to fly the J-10 fighter at any time."

"As for the personnel of the first flight, it is currently tentatively Lei Gang, who is also the test pilot of your previous WS-10 when it made its first flight!"

The training of pilots is much faster than the preparation of J-10 fighters, and now they are almost all waiting for fighters, waiting to fly the latest generation fighters of the motherland into the sky!

Even in the process, it is not necessary to give your own life!
