Chapter 474 "Taihang" Engine Design Review Meeting (10,000 per day)
Of course Chang Haonan, who is far away in China, will not know that his colleagues at MIT have already crossed the wrong road due to a moment of negligence and many coincidences. Going further and further.
In fact, he originally thought that the other party would soon realize that something was wrong.
I can only say that it is still overestimated after all.
For Chang Haonan, after helping Liu Yongquan get the film cooling test on track and obtaining some of the most basic data, the overall design plan of the turbofan 10 should be finalized. .
Although the previous plan was to design and manufacture two legs to walk at the same time, there was still a question of whether to step the left foot first or the right foot first.
Qian Lao once summed up a very important core point of view in "System Engineering Theory". To make any technical product, we must start from the existing conditions. We do not need to insist on the advancement of a single technology, but we must Ensure the rationality of the overall design.
Although it has been several months since Chang Haonan took over the Turbofan 10 project, and the progress has been progressing by leaps and bounds, strictly speaking, most of his previous work still falls into the category of "pre-research".
Until the general technical route is decided, the research and development work of all subsystems will be unable to be carried out.
So, this is definitely the top priority of the entire project.
It is also a process that he hopes to expose China’s aviation development researchers to.
In addition, such a big matter cannot be decided by Chang Haonan alone, or by gathering together a few core members of the 606 institute to pat their heads together like the first time.
Although letting him serve as the chief designer of a key aircraft engine at a young age has reflected the high degree of recognition and trust in him in the organization, trust is trust, and things should be done according to the rules. .
To officially transfer from pre-research to model development, design review meetings still have to be held.
Of course, with Chang Haonan's current reputation in the aviation industry system and even the entire military industry system, there will definitely be no shortage of small "privileges".
For example, under normal circumstances, the Commission of Science, Technology and Industry for National Defense and the General Armament Department decide how, where and when the review meeting will be held. Even in order to save time and resources, some non-key models are packaged according to categories. Focus on the review again.
But for Chang Haonan, he only needs to prepare relevant information and call Ding Gaoheng to decide these details by himself.
Of course, the comrades from the general offices of the two ministries are responsible for organizing the conference, so he does not need to worry about it.
The main research and development units of the turbofan 10 are 606 Research Institute and 410 Factory. This meeting was naturally held in Shengjing.
However, due to Chang Haonan's request, in addition to the experts and leaders who participated in the review, as well as the main responsible comrades of the turbofan 10 R&D team, there were also many comrades involved in R&D.
As a result, the originally planned venue, namely Conference Hall 606, became a bit stretched.
Finally, under the personal coordination of Cao Gangchun, the director of the General Armament Department, they borrowed the opportunity to use the agency auditorium of the Shengjing Military Region.
Old building, but the advantage is that the place is large enough.
More importantly, it is very close to the guest house of the Shengjing Military Region——
A design review of this scale will definitely not be completed in one day, and local researchers can go home. There are dormitories, but participants from out of town have to be provided with a place to stay.
...
The night before, Chang Haonan brought relevant design materials and arrived at the venue in his Jetta King.
As a large military region at the corps level, the Shengjing Military Region garrison is an important military area that no one can enter.
Even if Chang Haonan and the others come from military industrial units that are closely related to the army, they are still non-military local personnel after all.
So after waiting at the door for a while, I saw a camouflage-painted Mitsubishi off-road vehicle driving out of the courtyard, and a lieutenant colonel with the rank of Er Mao Er came out of the vehicle.
The latter said a few words to the sentry, and then motioned to the convoy outside to follow.
The group of people finally entered the military compound safely.
“I think the security of our military industrial unit must be upgraded according to this standard in the future.”
Chang Haonan turned back and glanced at the sentry who had just finished saluting at the door, half-joking said.
Zhu Yadan, who was driving, curled his lips:
"Chief, it's not that I look down on the comrades of the local security department, but if nothing else, it would be difficult for them to stand guard outside 24 hours a day..."
Shengjing also equipped this car at the beginning. A full-time driver is required, but this will require an extra seat.
Furthermore, according to Zhu Yadan, drivers who have not received special training will only operate randomly once they encounter an emergency, and they will easily make mistakes.
It is still reliable to keep the steering wheel in your own hands.
So within a few days, the other party was invited away by her.
Of course, Chang Haonan also knows that what Zhu Yadan said is the truth:
"A good wish...and having said that, as the level of scientific research in our country gradually improves, this aspect really needs to be paid attention to."< br>
"I think...as long as we protect you, other places are not so anxious."
During the time when he followed Chang Haonan as a driver and bodyguard, Zhu Yadan finally saw this What is "white jade pillars holding up the sky, purple gold beams supporting the sea".
She estimated that at least 70% to 80% of the new technologies and equipment she had heard of in the past two years were directly or indirectly related to Chang Haonan.
"No, not so."
Chang Haonan quickly waved his hand:
"Although I did play a role in some key positions, the results are always achieved by all comrades working together. ..."
While the two were talking, the motorcade had stopped at the entrance of the government auditorium.
What surprised Chang Haonan was that the person waiting to greet them seemed to be...a bit high-level.
He looked down and checked what he was wearing before getting out of the car.
The leading officer stepped forward, but when he saw Chang Haonan's face clearly, he was obviously stunned for a moment. But after all, he was a seasoned veteran, so he quickly adjusted himself and shook hands with Chang Haonan:
"Are you Comrade Chang Haonan?"
"I am Commander Li Liangxin. On behalf of all comrades in the military region, I welcome the arrival of comrades from the military industry system!"
When the Internet was not very popular, people's appearance could only be transmitted by word of mouth.
Besides being handsome, Chang Haonan's biggest feature is naturally his youth.
So Li Liangxin, who had received a call from Cao Gangchun in advance, was actually mentally prepared.
I knew I was young, but I didn’t expect to be this young...
This enthusiastic opening speech was completely beyond the expectations of Chang Haonan, who had just gotten off the car.
"You are too polite, too polite..."
I have seen a few generals of the same military rank, Chang Haonan, but this is the first time I have met him with this look.
“Hey, you’re welcome, you’re welcome, my old friend Deputy Commander Zheng wanted to fly back from Anshan when he heard that you were coming for a meeting, so I stopped him...”
As he spoke, he led Chang Haonan up the steps outside the auditorium, and then he remembered to explain further:
"Oh, Deputy Commander Zheng is the deputy commander of our Shengjing Military Region and the Air Force of the Military Region. Commander, Zheng Shenxia, has the same surname as Commander Zheng Liangqun, whom you should know, but they are not from the same family.”
Now Chang Haonan finally understood the crux of the matter.
The troops of the Shengjing Military Region were the ones who achieved the first air combat results of the Chinese Air Force in 30 years.
Although this incident has not been publicly promoted even within the People's Liberation Army so far, it has given Li Liangxin a big face anyway.
Chang Haonan has made significant contributions to the two main combat equipment of aircraft and missiles participating in the war, so it is normal for him to be loved by the opponent.
“Military-civilian alliance and mutual promotion are all efforts for national defense modernization...”
Although the former himself felt very happy about it, he still had to be polite.
......
The review meeting is scheduled to be held tomorrow morning, so except for a few leaders who really can't get away, most of the participating experts have chosen to arrive one day early.
Therefore, when Chang Haonan prepared the materials needed for the next day's report in the main conference hall and was taken to the canteen of the agency guest house, he saw many familiar faces.
"Xiao Chang, this review meeting of yours caught me off guard."
Du Yishan walked up to Chang Haonan with a half glass of beer and patted him heavily on the shoulder twice.
Although he is nominally Chang Haonan's doctoral supervisor, even the King of Heaven cannot know the research progress of the turbofan 10 engine in real time without the authority.
So for Du Yishan, almost without any warning, he suddenly learned that his student had done something shocking.
Who would have thought that within three months of taking over the project, he would have finalized the overall design plan.
Of course, Du Yishan, as an expert in the field of aircraft design and Chang Haonan’s mentor, does not serve as a member of the review panel, either from a professional perspective or from the perspective of avoiding suspicion.
The person who is really responsible for the technical appraisal of this review is Liu Zhenxiang who is standing next to him.
But we are considered acquaintances with Chang Haonan.
"Xiao Chang, this is the third design review I have given to the Turbofan 10. I'm afraid it is unprecedented, right?"
Liu Zhenxiang also and Chang Haonan gently He clinked glasses and said in a slightly funny tone.
“The third time?”
Not to mention Chang Haonan, even Du Yishan didn't know much about this matter.
“Yes, shortly after the Turbofan 10 project was established ten years ago, there was a design review, but at that time we couldn’t even copy other people’s engines, so naturally we failed in the end.”
“Later between 1993 and 1994, they used a new plan to drive it for the second time. They came up with the design of a CFM56 core engine. Looking back now, it is basically similar to the F110 engine, but the design is There’s no problem, but we can’t meet many technical details, so we’ll let it go.”
“The third time, it’s now.”
Chang Haonan said yes. Guys, I know that the turbofan 10 is rough, but I never thought it would be so rough.
"But, this time, with our Comrade Xiao Chang here, I still hold an optimistic attitude, otherwise, nothing will come..."
Liu Zhenxiang picked up the cup and poured out the remaining contents. He drank the wine in one gulp and waved his hands at the same time.
"Don't worry, Academician Liu, this time will definitely be the last design review."
Chang Haonan said in a deep voice.
“So confident?”
Liu Zhenxiang and Du Yishan looked at each other and smiled in unison.
"Well...the several key technologies that have been solved are going quite smoothly, and they are consistent with the design plan, and there will be no big problems!"
