To build an aircraft carrier battle group, you must first have an aircraft carrier, destroyers, frigates, and supply ships, as well as carrier-based aircraft, early warning aircraft, and anti-submarine aircraft, plus underwater submarines and various types of missiles on board. A huge project.

However, any project can be split into more detailed sub-items.

For example, according to Chen Nian's plan, he still intends to start with aviation first, continue the technology of the 22nd project, and get out the early warning aircraft first!

The reason why we don't engage in carrier-based aircraft is because the Varyag is still an empty shell, and we don't know that it will be a year of the monkey before it can be repaired.

Provide technology with plug-ins?

Chen Nian tried it. The complete construction technology of an aircraft carrier requires 1100 source points. If he saves hard, he will not be able to save it for a lifetime.

Therefore, step by step, from small to large is the best solution.

Thinking of this, Chen Nian sorted out his thoughts a little bit, and wrote down the words Digital Array Radar on the paper.

Compared with active phased array radar, the principle of digital array radar is more complex and more difficult to manufacture, but also, the performance is better. It cancels the phase shifter and uses the computer to control the emission time of electromagnetic waves to create phase difference. Higher in precision and agility.

It is precisely because of this that the technology it needs covers multiple fields such as semiconductors, electromagnetics, and computers.

In this case, parsing it is also extremely costly at the source.

A full 4 points!

Moreover, this is only an analysis of the technology of the radar itself, excluding the basic equipment needed to manufacture it.

From the information Chen Nian knew, the front-end technologies involved in this thing include photolithography technology, high-precision machine tool technology, gallium nitride synthesis technology, and so on.

It is really not that easy to actually create it, you must break through the front-end technologies one by one.

It's like a sea of ​​smoke!

Chen Nian sighed.

However, he quickly reacted:

I have a team now!

Why not leave this kind of information collection work to the consultant working group?

Thinking of this, Chen Nian immediately called Chen Guo, who naturally agreed without hesitation, telling Chen Nian to give him a list of key technical difficulties in about three days.

Putting down the phone, Chen Nian nodded in satisfaction.

This way of working is indeed much simpler than fighting alone.

You only need to be responsible for learning and analyzing, and then participate in decision-making when necessary.

However, the semiconductor chip manufacturing technology involved in digital array radar covers a lot of material science knowledge, especially the knowledge of silicon materials.

It seems that in the future, my investment in the course Materials Science can be gradually transferred to the field of semiconductor silicon materials...

While writing his future plans on paper, Chen Nian was thinking about the candidates for the teacher. At the same time, the No. 22 project team, which had cleared all obstacles, was going all out to realize his last plan...

...

Did you get the data from the first test run? What's the problem? Just talk about the key points, our time is tight!

Wang Xianguo stood in the main control room of the test bench, his eyes fixed on the engineer in front of him.

His fingers trembled slightly. In fact, this kind of trembling had already started several hours ago, when this domestic F119 was installed on the test bench.

He was too nervous, because what was about to be presented to him would be two possibilities:

Either it was a success in one fell swoop, and the F119 showed performance that met the use standards and became a milestone in the development of China's aviation industry.

Or, it is to exit sadly, and after consuming a lot of money and resources, it is still unable to achieve satisfactory results.

If this is the case, not only the F119 project, but the entire No. 22 project may be affected, and many researchers, including himself, may also become sinners...

Seeing his serious expression, the engineer on the opposite side hurriedly took out a report that was obviously rushed, and replied loudly:

Reporting to the leader, the data is performing well!

According to our data, the middle thrust of this engine is about 12.2 tons, the maximum thrust reaches 18.6 tons, and the thrust-to-weight ratio is 10.9. In extreme cases, it can even break through to 11.5.

The turbine inlet temperature is about 1700 degrees, and the fan temperature fluctuates between 900 and 1000 degrees.

Hearing this, Wang Xianguo's heart skipped a beat.

The temperature is too high.

You must know that even the turbine inlet temperature of WS-10S is only about 1480 degrees. The difference between these two hundred degrees is enough to exceed the heat resistance and creep resistance limits of many materials, causing major problems.

How about the performance of the turbine and fan blades?

Wang Xianguo asked impatiently, he was afraid of hearing bad results.

No problem! The new TBC and Alloy C materials are very effective, and all creep and high temperature deformation are within controllable range!

We checked the combustor, the turbine, the high-pressure compressor, and they are performing better than we expected!

Wang Gong, here is the detailed report. You can read it yourself. Our preliminary suggestion is that we can announce the success of the ground test!

Most of the data performance is better than the design results, and the stability and reliability are extremely high. As long as the high-altitude experiment is completed, this engine can go on the plane!

The engineer's tone was a little excited, but Wang Xianguo stood up involuntarily.

In fact, compared with the engineer in front of him, his expectations and emotions for this engine are not weak at all.

He has touched almost every bolt and rivet with his own hands;

He has personally inspected almost every pipeline and every sheet;

For him, this engine is really like his child. He watched it slowly transform from a pile of data into scattered materials, and then form components from materials, and finally assembled into the dream machine in front of him. general engine.

And just today, this engine has just completed its first major test in its life.

Ground test drive.

The results of this big test will determine whether it can really go to the sky.

And it completed the exam perfectly, and it can even be said to have completed it with a super full score score!

With such a result, how could he hold back his emotions?

You must know that this is not only his achievement, nor the achievement of the project team, but the achievement of all aviation people.

He still remembers that when the WS-10 project was made public, the former colleagues who had left the 606 Institute to work in foreign companies unabashedly laughed at the whims of the 606 Institute in front of him, and tried their best to persuade him to run away.

But at that time, he quarreled with each other passionately, and finally exchanged harsh words with each other. One said that he must build WS-10 to slap his face severely, and the other said that he would wait to see the jokes of the 606 Institute and wait to see the self-righteous powerful country people joke.

——

Then, for a full 10 years, I was being laughed at by others.

The WS-10 project has come to a standstill, and the new project has died before it is established. It is seeking to purchase the Al-31 engine, and it has to endure various harsh terms from Russia.

For Huaxia, hope seems to be getting slimmer.

And for those traitors, this is a sign of their complete victory...

Every time he thought of this, Wang Xianguo felt uncontrollable emotions rising in his heart.

That kind of feeling, as if you blew something that can never be achieved, and every time you think of the scene when you blew this brilliance, you will fall into endless anger, shame, and panic.

Seeing that the WS-10 project was facing a miscarriage, this negative emotion was magnified to an extremely terrifying level, and it almost crushed him.

But fortunately, it was at this time that the WS-10S project was established.

Subsequently, in less than three months, WS-10S followed the J-10 change to heaven.

The slaps that fell on her face for the past ten years finally slammed back hard.

Wang Xianguo felt that he was an ordinary person, and he didn't feel relieved or relieved.

Nor did he forgive the foreign friend who betrayed this land.

He just felt very refreshed, and even hoped that there would be more slaps like this.

And now, F119, this engine beyond the times is right in front of my eyes.

It is no longer a slap, it will be a heavy punch, a cannonball, and a thunderbolt that will fall on the heads of all the enemies.

Wang Xianguo let out a long sigh of relief, and then picked up the phone at hand.

After a few seconds, the call connects.

Boss Lin, I'm Wang Xianguo.

F119 passed the ground test with excellent data performance, and the high-altitude test is expected to go well.

Optimistically, within two weeks, we can complete the engine delivery!
