Take Off My Aviation Era

However, the surprise of the middle-aged man did not last long, and was soon replaced by a lingering sadness, because the problem he encountered was not solvable by metal felt and vacuum brazing. If it could be that simple, he would not have to be big. I ran all the way to Xingzhou City.

Thinking about it now, their successful factory still underestimated the difficulty of the model. They thought it was just an improved version of the J-7. In the past ten years, the successful factory has also done a lot of them. Basically, they have made minor repairs and improvements. There are no major changes in the manufacturing process. Just take the drawing, add something according to the specifications, or subtract something.

However, this time it was different. A Ⅲ was added after the J-7, which is like replacing the Tuba Road with American equipment. The entire shotgun is replaced by the gun. The J-7 is still the same as the J-7, but the internal structure, overall fatigue resistance, The craftsmanship inside has all undergone earth-shaking changes.

　　 At the beginning, the successful factory didn't take it seriously, until the technicians who followed the design came to the design office to realize that they were waiting for a new monster with a J-7 skin.

As for what the follow-up is, it is very simple, that is, the aircraft manufacturer draws technicians from the commissioning system to the aircraft design unit to track the design process, understand the design intent, give suggestions on the process problems encountered in the design, and make process preparations in the manufacturing process. .

　　 It stands to reason that difficulties in the manufacturing process are entitled to the design unit, and at some point the manufacturer’s opinions are still very important. After all, no matter how good the design unit is, it is useless if it can’t be manufactured.

However, the opinions of the technicians of the successful factory that we set up this time were directly ignored. The reason is simple. The F-7Ⅲ is a new model based on the Soviet MiG 21MF. Since it is a copy, it must be made decently. , There can be difficulties, but they must be resolved!

　　 The success factory, who was stunned by the superiors, had no choice but to go back with the drawing. As a result, the more I looked at it, the more my scalp began to tingle. I haven't done many things in the factory.

　　 However, knowing that I have fallen into the big pit, Success Factory still has to bite the bullet. There is no way, the higher-level task is dead, and you have to do it if you don't do it, or you will have no food.

　　 So even though the successful factory knew that it was not easy, it was still on the trial production task of the J-7Ⅲ. The result was that it was harder than expected. It is an exaggeration to say that it is difficult, but one step at a time is definitely not an exaggeration.

Take the third workshop of the successful factory where the middle-aged people are. They need precision machining for several important parts, and the previous experience and technology of the third workshop are useless at all. The result of the push is the progress of trial production. Not to mention extremely slow, even if it is manufactured, it may face the risk of substandard quality.

　　 The middle-aged person felt a little distressed when thinking about the parts that were judged to be scrap, and couldn't help but look up at Tang Lili who was opposite.

　　Since Sing Chew Aircraft Design Institute sent this woman over, the nightmare of their workshop has begun, but there is no way, who is the designer of the design unit.

Many production links of aircraft manufacturers need to communicate face-to-face with designers in order to deal with problems in the first time, such as fuselage structure, wings, landing gear, hydraulic system, cockpit cover, etc., from component trial production to complete aircraft assembly and test flight. Various problems are fed back to the design, and the designer will modify it again and again to make the design perfect.

　　 Tang Lili is engaged in the structural strength of the aircraft. Because of the slow preparation of the No. 10 project, she was temporarily transferred to the F-7Ⅲ project team as a designer in order to accumulate design experience.

Now that she was sent to the first-line factory and saw that the aircraft parts that were only on drawings in the past have become three-dimensional objects, Tang Lili sincerely felt that her trip was worthwhile, and she was engaged in structure, so Tang Lili naturally wanted to use it. Extreme.

So she used her expertise to analyze the structural strength and safety of each component of the aircraft, and established a mechanical model based on this, so as to further analyze the load, stress and strain to find out the physical meaning, the force state of the structure, and the way of force transmission. And then solve it by mathematical model.

　　 Then, Tang Lili had the theoretical Heavenly Sword and Dragon Sword, and even the third workshop of the Chenggong Factory smashed all directions.

　　 Which hole was drilled a little bit too far, and the thickness of which joint ear piece was two thinner, the workshop craftsman and master craftsman agreed, but Tang Lili was not accommodating.

For this reason, the director of the crafts room of the third workshop specifically asked her to explain. Tang Lili didn’t talk nonsense, and piled the half-person-high mathematical model in front of the director of the crafts room of the third workshop. And go.

After 　　, Tang Lili even blocked and killed people in the third workshop. The Buddha blocked and killed the Buddha. She said that the 3214 component was not good, and the 3214 component was invalid; she said that the 1786 box was not standardized, and the 1786 box had to be recycled as non-metallic.

　　 No matter the 3214 parts or the 1786 frame, it is a large opening with a trial cost of hundreds of thousands, and it is ruined in one sentence. It is not an exaggeration to say that it is a golden mouth.

A middle-aged person as the workshop director of the third workshop ~www.readwn.com~ Even if he knows that design and manufacturing are contradictory, the design is perfect, and the pursuit of manufacturing is to reduce costs and improve efficiency, but like Tang Lili, it can be tens of No matter how strong the foundation of their workshop is, they cannot withstand such a waste.

　　 So he gritted his teeth and started to upgrade his technology. Instead of destroying the costly parts that open the door in vain, he might as well use the money to improve himself. Since the existing equipment and technology cannot effectively complete the trial production of the F-7Ⅲ, learn new technologies and introduce new equipment to meet the trial production requirements of the F-7Ⅲ.

In this way, the successful factory took advantage of the opportunity of trial production of the J-7Ⅲ to start its own technological upgrade road, but this road was not going smoothly. After all, many technologies and equipment are still blank in China, and they can only be solved by importing. However, it is embarrassing that you cannot buy certain key equipment and technology even if you have money, because foreign countries will not sell you at all.

For example, the shot peening technology that worries him most, the director of the third workshop, contacted Boeing in the United States earlier, and wanted to introduce two sets of spray-finished machines from them. Boeing was very polite and led After they visited for a while, they said: "Our equipment is self-developed. Due to their uniqueness and uniqueness, we cannot sell them, but you can take a look at our other products, such as the latest Boeing 737... …"

　　 is very polite, but the main idea is just one sentence, you can read it, but we don’t sell it!

If you can’t buy it, you have to do it yourself. The question is whether you have the experience and skills, and you can’t do it for a while. Just when the workshop director of the third workshop was in a state of desperation, Tang Lili suddenly found him and said that her lover is Yonghong. Someone in the factory has developed the related technology of the spray-finished machine.

　　 The workshop director of the third workshop was shocked when he heard it, don't say anything, see you!
