The military-industrial scientific research system of the academic master.

Looking at the data report in front of him and Chang Haonan who still seemed calm and relaxed next to him, Yan Zhongcheng subconsciously turned around and left the control room pretending to be nonchalant.

He didn't want his tears to be seen by too many people.

Twelve years.

Twelve years have passed since the Kunlun engine project was officially established in 1984.

For China Aviation Industry, which has never successfully developed an aerospace engine from scratch before, there are too many things to learn and lessons to make up.

From the beginning, this project was ill-fated.

Even Yan Zhongcheng himself can't remember exactly how many problems he has faced in the past twelve years.

At the beginning, the combination of the three-stage low-pressure compressor of the turbojet 13 engine and the first seven-stage high-pressure compressor of the downsized "Spey" engine did not match. The engine would enter surge almost immediately as soon as it was started.

They had to redesign the fourth stage of the compressor and finally allowed the engine to start working normally.

Later, because the temperature in front of the turbine of Turbojet 14 was higher than that of Turbojet 13, which far exceeded the endurance of the turbine blades themselves, they had to use active film cooling technology for the first time on the high-pressure turbine.

Due to no engineering application experience, Factory 410 was unable to produce qualified products with air film holes for several years. Root fractures of high-pressure turbine blades were almost the main part of Yan Zhongcheng's nightmare during that period.

Then there was oil leakage from the pipeline, oil interruption, and low afterburner ignition success rate...

If the story of these twelve years were written into a book, the most appropriate title would be "Learning Engine Design and Manufacturing from Scratch."

It can be said that the entire research and development process of the Turbojet 14 is a cycle from one setback to another.

At first, Yan Zhongcheng would feel excited because he led the team to overcome a certain technical problem.

But soon, he no longer felt similar emotions.

Because the solution of one problem often means more problems.

It was like groping forward without moonlight and darkness, not even knowing if I was on the right path.

Thinking of this, Yan Zhongcheng sighed, leaned against the wall of the corridor at the door, put his right hand into the collar of his shirt, and touched a scar on his left shoulder.

That was left over from a failed test run.

The fan blades flying in the explosion almost cut off half of his left arm, so that to this day, he cannot lift his left hand for a long time.

Many people left midway.

To be honest, Yan Zhongcheng understood.

What these people fear is not suffering, suffering, or even bloodshed, but losing hope and direction.

This is why he had to let Chang Haonan think clearly before deciding whether to join the power joint research team.

Because it takes extraordinary courage to plunge headlong into the dark night.

But it was obvious that he underestimated this young man after all.

The other party is not afraid of the long night at all, because he himself is the torch that lights the way forward.

Now, there is light.

The road is clear.

……

In the control room, Chang Haonan certainly knew why Yan Zhongcheng chose to leave alone when everyone was celebrating.

As a reborn person, he knows the latter's experience during the development of the Turbojet 14.

It only took more than a month from the accident of the No. 01 prototype to coming up with a new design with performance comparable to the F404 engine.

Of course, there is systematic help in this, as well as the reason why a reborn person is prophetic.

However, without Yan Zhongcheng’s twelve years of persistence, Chang Haonan’s one-month miracle would not have happened.

Compared to the sentimental Yan Zhongcheng and the calm Chang Haonan, the emotions of most people in the control room were much simpler.

Excited and happy.

A jubilation.

For the vast majority of engineers in the 606 Institute, this is even the first time in their careers that they have experienced the feeling of success.

Prior to this, the best aviation engine China could produce was the turbojet 13.

The technical level is roughly the same as the J60 in the early 79s, but the overall performance is even weaker.

And the Turbojet 14 in front of them had already pushed the J79 several positions away.

It can even be compared to the F80 of the mid-404s to a certain extent.

Jump fifteen years!

Of course, this calculation method is definitely not accurate enough.

The F404 is just a less dazzling product in the overall development process of the US aviation industry, and it is far from the limit of that era.

The Turbojet 14 is the only seedling growing in the still barren soil of China's aviation industry.

If we have to say that the gap between China and the United States in the field of aviation power has been narrowed to within ten years, I am afraid it is still a bit too optimistic.

But so what?

The huge breakthrough at the technical level is real.

For the first time, China had its own aviation power.

And you must know that a project like the Kunlun engine does not just represent one model.

If all test projects can be successfully completed, a series of new products can be developed based on the mature core machine of the turbojet 14.

The development of the entire China aviation power industry will benefit from this.

Project research and development also pays attention to positive feedback.

In the past few decades, aviation engine models have been used as supporting equipment for aircraft models. Coupled with insufficient investment, the aerospace power field with already weak foundation has become even worse. In many cases, even if a complete set of technical data from the Soviet Union is obtained, they can be copied. There is a certain gap between the performance of the finished product and the original version.

Looking back at the aircraft industry, the first J-1956 was assembled in 5. Two years later, in 1958, the J-1, which was completely designed independently, successfully made its first flight.

Although the JJ-1 only built three prototypes and did not achieve mass production, that was mainly due to changes in the flight training system and...

Factory 410 is unable to provide qualified Eruption 1A engines.

Although there are limitations from various objective factors, such a sharp comparison between the two makes it even more obvious that the aviation power department is a bit "not up to par".

In the nearly 40 years that followed, this kind of engine "holding back" almost always accompanied the development of the entire Chinese aviation industry.

So much so that people who are engaged in aviation development feel a bit unable to hold their heads high.

But this time, the situation is different.

The original design of Project 83 is at the level of a normal second-generation aircraft. Even after some improvements by Chang Haonan, it can be regarded as a "quasi-third generation" at most.

The turbojet 14 provided by our aviation power department is also a "quasi-third-generation" engine with performance that is close to that of the F404.

Not only is it not lagging behind, it is even ahead of the aircraft model to some extent.

Finally feel proud for once!

But at this time, someone among the people celebrating each other suddenly realized something.

"The person who presided over the modification of the compressor design this time is also named Chang Haonan. The person who presided over the modification of the aircraft design before seems to be also named Chang Haonan. How do you feel..."

The man scratched his head and looked at Chang Haonan, who was looking down at the test report outside the crowd.

As an ordinary engineer in the 606 Institute, he certainly had not participated in the wing design modification work that the 601 Institute was responsible for. He only heard about it in exchanges with his colleagues.

"hiss……"

"This can't be the same person..."
