After two or three months of running-in, the new core machine of WS-10 using high-temperature superalloy and carbon-carbon composite materials developed by the Rocket Research Institute was finally made.

The turbine disc using nickel-chromium-iron alloy adopts the powder metallurgy process, which was very rare in China before.

However, this process is not particularly mature at present, and all aspects of industrial equipment are basically changed by Zhang Xingyang and the engineers little by little.

In addition to being able to meet the production of turbine disc test products for the rocket research institute's own new engine, it can also provide a little bit for the WS-10 project team for test use.

Of course, the small quantity does not mean that the things made by the Rocket Research Institute are expensive.

In fact, the main constraint on production at this stage is the number of equipment and the number of workers who can operate it.

As long as the equipment and workers are in place, mass production can be achieved in minutes.

"What about the performance test results?"

Zhang Zhengjiang looked at Chen Zhiqing very anxiously, who had just finished testing the turbine disc made by the Rocket Research Institute.

Chen Jianqing held the report that had just been spit out of the printer and still smelled of ink, and he was overjoyed:

"Compared with the previous turbine discs we manufactured, the performance of the new turbine disc has improved by almost 20%."

"In particular, the high-temperature powder metallurgy technology they use seems to be very high, the whole turbine disc is molded in one piece, and the crystal structure is also very good."

Hearing Chen Jianqing's good news, Zhang Zhengjiang was also very happy, and took the report and kept reading it.

I want to confirm with my own eyes whether what Chen Jianqing said is true.

The new turbine disc sent by the Rocket Research Institute is not really that good.

Zhang Zhengjiang glanced at the data on the report little by little.

Indeed, the performance has really improved a lot compared to the turbine disc they had been using before.

Especially in the critical high-temperature performance test, it has been improved by nearly 40%.

The extreme temperature was raised to an altitude close to three thousand degrees.

"The Rocket Research Institute has really made a lot of achievements in terms of materials!"

Zhang Zhengjiang smiled, flicked the report in his hand, and said to Chen Jianqing.

Rubbing his mind that was a little dizzy because of long hours of work, although Chen Yuanqing was a little tired, he still said happily:

"Now, our engine has a relatively solid core!"

In the previous life, the WS-10 could not be loaded with the J-10 at first, and it was a thorn in the hearts of many people who could never get over.

In the past ten or twenty years, in this regard, everyone has not been able to raise their heads every time they are faced with the accountability of the Chinese people.

The big problem is that the materials of the engine are not up to standard, and the processing technology is not in place, so that the engine cannot meet the standards for the use of military aircraft.

"yes, but that's not a good thing!"

Zhang Zhengjiang sighed.

The pace of development at the Rocket Research Institute has greatly exceeded the speed he envisioned.

Originally, he thought that no matter how fast the speed of the research institute was, it would take a year or two.

That's why he promised Zhang Xingyang that the research funds would not be owed to the Rocket Research Institute.

At that time, Zhang Zhengjiang's idea was that although the WS-10 project funds are not particularly sufficient now, it can still be done by slowly giving them quarterly.

But what people didn't expect was that the Rocket Research Institute was burning money and throwing progress almost every day, and in less than four months, the materials that met or even exceeded the requirements were released.

However, with the new turbine comes a long bill for R&D expenses.

Seeing the numbers above, even Zhang Zhengjiang, who has always been steady, was so frightened that it was difficult to attach.

"But they are also too good at spending money, spending tens of millions of dollars on R&D in four months."

Zhang Zhengjiang couldn't help but sigh.

"All of a sudden, the R&D funds we just approved before have to be put in!"

In this regard, Chen Jianqing did not care.

After all, with such a strong material, it is actually completely worth spending so much money.

"Teacher Zhang, don't think so, just spend so much money to solve our big problem."

"To be honest, it's worth it!"

Zhang Zhengjiang did not understand these truths.

This high-temperature powder metallurgy process and integrated molding process should be solved by the WS-10 project team itself.

It will cost hundreds of millions of dollars, and I don't know how long it will take to develop successfully.

For the project team, which is particularly short of time, it is possible to solve the problem in such a short time.

Not to mention tens of millions, even hundreds of millions are worth it.

Because this matter can't actually be viewed from the perspective of the WS-10 project team alone.

If the angle of view is put to a higher height, as long as the WS-10 can be successfully developed, it will be equipped with a J-10 fighter.

Then there is no need to import AL-31F engines from the north Da Mao family at a high price, which can save a lot of money.

Even if the performance of the newly developed WS-10 engine is not particularly superior, it does not matter much.

As long as you have it, then when you introduce the negotiation, the other party will not dare to ask for the price, and you can also save a lot of money for the country.

In fact, this is true not only in the field of engines, but also in many industrial sectors.

When you don't have it, foreign manufacturers have the pricing power to shout as high as they want.

And after you break through the core technology, the other party will no longer be so tough on you.

This is the case with the lithography machine, which was particularly famous in later generations.

When you don't master the core technology, the other party can shout that you won't sell it to you, and when you break through the other party's technical blockade, you will start to call for cooperation between the two sides.

"Now, we can try to install the testing machine right away."

Zhang Zhengjiang looked at the report and sighed a little.

"I have coordinated with the Air Force before, and they have agreed to give us a Su-27 for engine testing."

While Zhang Zhengjiang was talking about the installation experiment, Chen Jianqing talked about the results of the communication with the Air Force.

At this time, the J-10 has not yet been completely finalized, and it is still in the test stage, especially because the engine problem has not been fruitful, and some details on the aircraft fuselage have been dragged because the engine has not been finalized

However, in terms of overall progress, the J-10 project team is much smoother than the WS-10 project team, and it has been steadily advancing.

If the WS-10 wants to conduct engine experiments, it can only be tested on the Su-27, which was introduced from the Da Mao family just four years ago.

The first Su-27, although later it was always thought that it had quite a few problems.

But as a twin-engine heavy third-generation fighter, it was still very advanced at this time.

Its platform design is a place where there is a lot of deep cultivation, and it is able to develop a variety of fighter models.

It is indeed more than enough to use it as an experimental platform for the WS-10.
