A big country of aerospace with black technology

Although the core engine was completed, the assembly of the entire aero-engine still took the project team a week.

This speed cannot be regarded as very fast, after all, the entire prototype test machine was actually completed two years ago.

This time, it mainly replaced some parts inside it.

In particular, the turbine disk and tail nozzle developed by the Rocket Research Institute were replaced.

Although the size of the WS-10 engine is not huge, the cold body with complex metallic luster can still make people feel its industrial beauty.

Everyone standing in front of it, all sighed with emotion for its violent aesthetics.

Before the introduction of new materials from the Rocket Research Institute, the project team's design thrust for the WS-10 engine was 120KN.

In fact, this thrust is far from reaching the limit of the core engine. It is only because of the problems of materials and processing technology that the thrust has to be reduced again and again.

This time, the problem of some materials has been solved, and the thrust can also be raised.

In particular, the materials developed by the Rocket Research Institute basically have improved high temperature resistance.

The temperature of the high-temperature gas of the engine is increased by at least 20%, so that the thrust of the engine can reach the level of 130KN.

Coupled with the use of composite materials for the tail nozzle, the weight has dropped a lot, and the aircraft can carry more fuel, and the combat radius has greatly increased.

Although the WS-10 is not an engine specially developed for the Su-27, the J-10 was originally a third-generation fighter in the same line as the Soviet fighter, and the compatibility between the two is quite high.

It took Zhang Zhengjiang a lot of energy to get the WS-10 installed on the Su-27 for testing.

After all, the Su-27 at this time is still relatively rare in China.

The unit price of the first batch of 24 Su-27s was 30 million U.S. dollars, although a combination of 35% foreign exchange and 65% commodities was used for payment.

But still very expensive.

It was only this fight that Zhang Zhengjiang managed to get his grandpa to sue his grandma for.

Of course, there is no way to do this. Apart from the Su-27, there is no other better test platform in China.

The nimble engineer was constantly busy at the tail of the plane, dismantling the AL-31F from the original plane.

"Old Wang, can you finish it today?"

Zhang Zhengjiang stared at the pipeline exposed at the tail of the Su-27, frowned and asked the engineer who was still flipping through technical manuals full of Russian.

Among the thick and tome technical manuals, there are various technical specifications densely packed, and only Wang Xu, who has been dealing with Lao Maozi all the time, can read them.

But he can't guarantee when he can finish it now.

Because the Su-27 has not been introduced into China for a long time, everyone still doesn't know much about this heavy fighter that can be regarded as a top third-generation aircraft even if it is placed in the world.

At this time, Yingjiang's F-22 has not yet been tested, let alone officially deployed to the troops, so the Su-27 is definitely one of the most advanced fighter jets at this point in time.

When Wang Xu was young, he went to Mao Xiong's house as an exchange student to study aircraft maintenance, and worked in the Gongqingcheng Aircraft Factory for a while.

Therefore, Wang Xu is absolutely familiar with the context of the Soviet fighter.

But this is only limited to some second-generation aircraft. For the world's most advanced third-generation aircraft like the Su-27, it was only a few years ago that we started to contact them.

The structure of the Su-27 is not as well understood as the previous fighters.

"It is definitely not enough to finish today. Today is just enough to remove the original AL-31F from the Su-27."

Wang Xu looked at the engineers at work and answered Zhang Zhengjiang's question.

"Give us another week, and it is estimated that we will be able to install the new engine."

In fact, Wang Xu thought about it for a week, and everyone didn't rest.

If you follow the normal engine replacement and maintenance process, it is normal to come for the first half a month.

In particular, the WS-10 engine is still an engine that everyone has not touched much before.

"That seems to be too late to present a gift to the National Day."

Zhang Zhengjiang murmured helplessly.

Originally, the project team did not have such an idea, but the efficiency and speed of the Rocket Research Institute gave Zhang Zhengjiang a little hope.

But now it seems that it is basically impossible to complete the test flight of the engine before the National Day.

But from the perspective of others, the development speed of the WS-10 project team during this period is simply amazing.

Especially Wang Xu, who has been dealing with the WS-10 project team before, knows that the progress of the project during this period is like riding a rocket.

Of course, it is not wrong to say that it is a rocket. After all, the main business of the Rocket Research Institute is to make rockets.

"By the way, how did you do it? The speed of research and development during this period is so fast?"

Finally, Wang Xu couldn't help but ask.

As the country's most advanced combat engine research and development project team, the WS-10 project team is not really in the team, and they still don't know the specific ways inside.

Even Wang Xu, who has been dealing with engines before, is not very clear.

However, there is no need to keep this matter a secret, especially since Wang Xu is about to join the WS-10 project team, so it is okay to disclose some information in advance.

"Thanks to the help of the Rocket Research Institute, they have recently made great progress in material manufacturing and processing, and have introduced many core materials suitable for engines, which have solved our big problems."

Speaking of the reason, Zhang Zhengjiang became energetic.

On the contrary, Wang Xu was a little puzzled after listening to it. His impression of the Rocket Research Institute was still at the beginning of the year.

At that time, the Rocket Research Institute had just failed to launch a rocket, and was facing serious problems such as personnel leaving and funding breakdown.

"Rocket Research Institute?"

Wang Xu frowned.

"Aren't they almost unable to survive?"

"Where's the money for development?"

Faced with Wang Xu's doubts, Zhang Zhengjiang was not surprised. After all, apart from the high-level people, generally only the people inside the aerospace system knew about the situation here.

It's normal for Wang Xu not to know these things.

"The new director of the research institute brought out several new materials, and used the material preparation process to revitalize a military factory that was about to close down."

Zhang Zhengjiang lit a cigarette and told Wang Xu about the drastic changes in the Rocket Research Institute in the past six months.

"Hey!"

"That factory is also lucky, and it even grabbed a lot of orders at the Canton Fair."

"The Rocket Research Institute has also received a lot of money. It's not that they have won a rocket launch mission for them, and they have started again."

Zhang Zhengjiang took a deep breath of cigarette and said lightly.

After listening, Wang Xu didn't ask any more questions.

It's almost enough to know so much, and it's better not to know the deeper content.
