The military-industrial scientific research system of the academic master

When Yang Fenghao said that he only had less than two months to prepare, many people's expressions turned into regret.

Although the aircraft for the air show do not have to be finalized. In fact, it is a common practice in countries all over the world to display models that are in the process of flight testing. However, it is still necessary to ensure that the model has basic stability and reliability. sex.

Originally it was about showing your face, but it would be bad if your butt was exposed.

However, it is already mid-September, and they have not even started manufacturing the prototype of the improved turbojet 14.

It seems difficult to catch up...

But no one was willing.

It would be fine if no one mentioned it, but after Chang Haonan mentioned the matter of participating in the air show just now, this idea has taken root in everyone's mind.

"I think Comrade Chang Haonan's idea is completely feasible."

After a long time, the deputy chief designer Liu Ming on the other side of the room was the first to speak:

"We can be prepared for this."

"If all goes well in the testing of the improved turbojet 14, then after installation, we can at least catch up to the end of the air show, which is enough for us to conduct a flight show."

Hearing these words, the people in Institute 606 showed some embarrassed expressions.

The words "all goes well" have never happened in China's aviation power field.

Although the improvement work this time is progressing quickly with the help of strong foreign aid, the expectations set by everyone are still relatively realistic.

But Liu Ming naturally also prepared a second plan:

"In addition, even if the testing work of the improved turbojet 14 has not been completed by then, we can still settle for the next best thing and use the old model engine to transfer the aircraft to the ground for ground display, which can be regarded as giving China a chance to compete. .”

The atmosphere in the conference room suddenly became lively again.

"This should work..."

"Indeed, the original turbojet 14 would still be fine if it was only used for transitional flights..."

"The ground demonstration is also here. At least it shows that even if we don't have the help of the Americans, we can still build the aircraft..."

Everyone is engaged in the military industry and has some understanding of the current situation.

In the conflict at the beginning of the year, facing a powerful enemy at its peak, we were indeed at a disadvantage.

So now we need an opportunity to boost people's hearts and morale.

The Xiangzhou Air Show is obviously a good choice.

Yang Fenghao also turned to look at Chang Haonan:

"what do you think?"

Chang Haonan's plan was naturally to complete the simulation test of the new engine as quickly as possible, and then conduct a flight demonstration in one step.

But he never liked to talk too much, and the plan proposed by Liu Ming also took into account various situations, and there was no problem, so he nodded:

"We have to prepare for the best and prepare for the worst."

After a pause for about a second, he continued to explain:

"That is to say, we must use the fastest speed to carry out prototype production and testing of the new turbojet 14 engine, but we must also do a good job in psychological construction for only ground demonstration."

Yang Fenghao, Liu Ming and Yan Zhongcheng had a brief exchange and all expressed their agreement.

"Then, I will communicate this matter with my superiors." Yang Fenghao's tone became serious:

"The 606 Institute pays attention to the connection with the 410 Factory. The production progress of the two test prototypes needs to be improved."

Yan Zhongcheng handed the document he had just signed to the secretary next to him, then stood up:

"No problem, because this improvement only involves the compressor part, so the 410 Factory only needs to re-manufacture the compressor part according to the new plan, and I will handle the docking work myself."

"..."

With the issuance of instructions one after another, the entire Project 83 project team started to get busy again.

According to Yang Fenghao and Yan Zhongcheng, Chang Haonan didn't actually need to do anything during the prototype production stage, so he could rest for a few days.

After all, anyone can see that during this continuous period of time, he is actually the one with the biggest workload.

"You are now a major contributor to our August 3rd Project. If I tire you out, Lao Du will probably come to me to fight for his life."

Yang Fenghao held the teacup and said cheerfully to Chang Haonan.

Ever since he took over the charge of Project 83, he has not been as happy and relaxed as he has been in recent times for nearly ten years.

Although they discovered two design flaws in the wing and engine in just over two months, the problem was solved quickly and easily because of Chang Haonan.

Chang Haonan did not reject the kindness of the two seniors, but he still made a new request:

"It's okay to take two days off, but I still want to find time to go to Factory 410 to see the production and manufacturing process of aviation engines."

In his previous life, he didn't have much knowledge about the aviation manufacturing field.

As a military screw, this is understandable. He only needs to complete his own work.

But now, as his influence on the entire Chinese aviation industry is growing, there are naturally more and more things that need to be paid attention to.

Of course, for the original turbojet 14, the manufacturing process and material level are not considered shortcomings - after all, there is still a more backward design level to cover.

But for the improved turbojet 14 and the turbofan 10 that must be overcome in the future, production and manufacturing are a completely unavoidable problem.

You have to plan ahead.

Although Yan Zhongcheng didn't know what Chang Haonan was thinking, he still nodded decisively:

"After all, you are the main designer of the new turbojet 14. Of course there is no problem in going to the 410 factory. However, if you want to enter the production workshop, considering safety issues, no matter who we are, we must follow the arrangements of the person in charge of the workshop."

…

Thanks to the work of the digital design team, the improved compressor has been fully parameterized during the design process. Therefore, the connection between the 606 Institute and the 410 Factory was very smooth. Chang Haonan only rested for two days before he was informed Production work on the prototype has officially begun.

The person responsible for taking Chang Haonan to visit the production process was Zhong Shihong, who had met him once before.

The latter is also a member of the turbojet 14 modification attack team, but because Chang Haonan was mainly responsible for numerical calculations and blade design, he did not have much contact with him.

"Is this the production of new compressor blades?"

Chang Haonan looked at the CNC machine tool in front of him. A piece of blank was being processed inside, but he couldn't see what the product was yet.

"That's right, it's a compressor rotor blade." Zhong Shihong nodded:

"Actually, you also know that because the compressor is a cold-end component, overall production is not difficult. Milling is the main process. The key points are mainly machining accuracy and stress relief. Relatively speaking, it is still a thermal component like a turbine. End parts are more difficult to process, but there are currently no production arrangements for this."

"It doesn't matter, I'm just here to intuitively experience the production process of aero-engines, so that when designing in the future, I can consider the convenience of manufacturing in advance."

"It would be best if possible."

"..."

While the two were talking, Chang Haonan noticed with the corner of his eye that in an inconspicuous corner of the workshop, there seemed to be a lot of finished products piled up.

But the blade detection area should be in the other direction.

"What are those?"

Chang Haonan asked, pointing in the direction of the corner.

Extra updates will be added in the afternoon as usual
