Chapter 474 "Taihang" Engine Design Review Meeting (10,000 per Day)
Of course Chang Haonan, who is far away in China, has no idea that his colleagues at MIT have gone further and further down the wrong path due to a moment of negligence and many coincidences.
In fact, he originally thought that the other party would soon realize that something was wrong.
All I can say is 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 for 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.
Mr. Qian once summarized a very important core point of view in "Systems Engineering Theory". To make any technical product, we must start from the existing conditions. We do not need to insist on the advancement of individual technologies, but we must ensure the rationality of the overall design. .
Although Chang Haonan has taken over the Turbofan 10 project for several months and the progress has been progressing by leaps and bounds, strictly speaking, most of his previous work still belongs to the category of "pre-research".
If the overall technical route is not determined, the research and development work of all subsystems will not be carried out.
So, that was 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 a few core members of Institute 606 to pat their heads together like the first time.
Although allowing a young man to serve as the chief designer of a key aircraft engine model has reflected the organization's high degree of recognition and trust in him, trust is trust, and things that should be done according to the rules cannot be omitted.
To officially transfer from pre-research to model development, design review meetings must still 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 and commissions are responsible for the organization of 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 head of the General Armament Department, they borrowed the opportunity to use the official auditorium of the Shengjing Military Region.
It's an old building, but the place is big enough.
More importantly, it is very close to the hostel of the Shengjing Military Region——
A design review of this scale cannot be completed in one day. Local researchers can go home to their dormitories, but participants from out of town must find accommodation.
…
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 units must be upgraded according to this standard in the future."
Chang Haonan turned around and glanced at the sentry who had just finished saluting at the door, and said half-jokingly.
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 assigned a full-time driver to this car at first, but this would occupy an extra seat.
Moreover, according to Zhu Yadan, drivers who have not received special training will only operate randomly once they encounter an emergency, which may lead to accidents.
The steering wheel is still in your own hands.
So within a few days, the other party was invited away by her.
Of course Chang Haonan also knew that what Zhu Yadan said was the truth:
"A good wish...and having said that, with the gradual improvement of our country's scientific research level, we really need to pay attention to this aspect."
"I think... as long as we protect you, other places are not so anxious."
While working as a driver and bodyguard with Chang Haonan, Zhu Yadan finally experienced what it meant to be a "white jade pillar holding up the sky, and a purple golden beam bridging 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 really."
Chang Haonan quickly waved his hand:
"Although I did play a role in some key positions, the results are always achieved by all comrades..."
While the two were talking, the motorcade had already stopped at the entrance of the agency's auditorium.
What surprised Chang Haonan was that the people 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 his condition 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 Cao Gangchun's call in advance, was actually mentally prepared.
I knew I was young, but I didn’t expect to be this young...
The enthusiastic opening remarks of this round were completely beyond the expectations of Chang Haonan, who had just got off the car.
"You are too kind, too kind..."
Chang Haonan, a general with the same military rank, had seen a few of them before, but this was the first time he came up with him like this.
"Hey, you're welcome, you're welcome. My old friend, Deputy Commander Zheng, heard that you were coming to a meeting and wanted to fly back from Anshan. 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 commander of the military air force. 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.
It was the troops of the Shengjing Military Region who achieved the first air combat results of the Chinese Air Force in 30 years.
Although this incident has not been publicly publicized so far even within the People's Liberation Army, it has given Li Liangxin a big face anyway.
And Chang Haonan made significant contributions to the two main combat equipment of the war, aircraft and missiles, so it is normal for him to be loved by the opponent.
"Military-civilian cooperation 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 a 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 committee 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 Tianwang Laozi cannot know the research progress of the turbofan 10 engine in real time without the authority.
Therefore, 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, as an expert in the field of aircraft design and Chang Haonan's mentor, Du Yishan 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 he and Chang Haonan can be considered acquaintances.
"Xiao Chang, this is the third design review I have given to the Turbofan 10. I'm afraid it is unprecedented and unprecedented, right?"
Liu Zhenxiang also clinked glasses with Chang Haonan 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, not long 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 a design of a CFM56 core engine. Looking back now, it is basically similar to the F110 engine. There is no problem with the design, but there are many technical issues. We simply couldn’t meet the details, so we let it go.”
"The third time? It's now."
Chang Haonan said in his heart, "Good guy, I know that the turbofan 10 is ups and downs, but I never thought it would be so ups and downs."
"But, this time, with our Comrade Xiao Chang here, I still hold an optimistic attitude, otherwise, no matter what I say, I won't come..."
Liu Zhenxiang picked up the cup, drank the remaining 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 in line with the design plan, and there will be no major problems!"
