Take Off My Aviation Era

　　 With an inquiring heart, Zhuang Jianye searched in the archives for a long time, but could not find the reason why Yonghong Factory did not continue to produce the "Speey" turbofan engine.

He didn’t look for it at all. He didn’t come to do the history of the factory. Even if he knew it, he wouldn’t pay for processing. Why bother? Anyway, I know that Yonghong Factory has the technical strength to produce the key components of the "Speey" turbofan engine. That's it, what's the matter with so much?

　　 So Zhuang Jianye began to organize his files again, and the result was a big guy, a meeting minutes stored in file cabinet No. 17, and the kraft file bag was also marked with the word "secret".

　　 After seeing Zhuang Jianye, his heart jumped a few times. He had never seen such a high-end thing in his two lifetimes. He wondered if he would first report to the director. After all, the documents with the word "secret" are quite relevant.

　　 Before he could put this idea into practice, he saw a line of standard stamps in the lower right corner "The confidentiality period has expired, please save it separately."

　　 Check again to see that it is the file in 1971. The confidentiality period is 10 years, and more than a year has passed. This is a sigh of relief and no longer politely opened.

　　 drew out the thick meeting minutes, but I couldn’t pull it out again.

　　 It turns out that the record above is a little-known history. It happened in 1970. In that year, a large plane from a certain country crashed in the X region, and the plane burned to the point of only wreckage.

After diplomatic negotiation, the country agreed to provide the factory technical data of the crashed aircraft. With the approval of the higher-level ministries and commissions, Yonghong Factory was instructed to organize a group of experts to rush to X Territory to remove the engine from the crashed aircraft and transport it back to the factory. .

　　 An air crash has long been the unprecedented luck of Yonghong Factory, which gave them the first luck to plan and map a large aircraft aero engine.

　　 So the factory immediately established a high-power turbofan engine leading group, under which a surveying and mapping design group was set up.

At that time, it was still in a special period, and the working class was paying attention to everything. Therefore, the current director of the second branch plant Xue Ronggui was the leader of the surveying and mapping design team, and the first chief engineer of Yonghong Plant Ren Qingxiang was the deputy team leader. Just the office director of the team, responsible for logistics.

　　 Today's chief engineer, He Ming, can't even be the deputy team leader, so he can only be the director of the surveying and mapping office. As for Qiao Chenyu, he is just a technician.

　　 It can be seen that the surveying and mapping design team at that time was full of talents, including almost all the elites of Yonghong Factory at that time.

　　 is just a gathering of elites to set up a surveying and mapping design team, which cannot change the backward scientific research conditions at that time. There was no special surveying and mapping site in the factory at that time, and the finished product warehouse could only be vacated as a place for engine storage and surveying.

　　 In order to keep it secret, soldiers from the army stand guard at the door day and night, and the windows dare not open. In summer, the warehouse is muggy and hot, and the temperature exceeds 40 degrees Celsius.

Of course, the harsh environment is not a big deal. The key is the engine itself. There are more than 20,000 parts in the forest. Therefore, the person who sets up the surveying and design team must first figure out the main structure of the engine, and then the material situation. , Assembly process, processing alternatives for supporting finished parts, electronic systems, lubricating oil systems, bearings, etc.

　　 In addition, these parts must be converted from imperial units to metric units.

In a word, the turbofan engine used in this kind of large aircraft is really too complicated. An iron bird that steadily flies in the sky for several hours, an aircraft that must safely take off and land countless times. It uses steel as its muscle. The complexity of the heart that uses fuel as its blood has reached the pinnacle of human wisdom.

　　 But it was designed and manufactured by people, not by gods. The whole process of converting energy into supersonic flight power is mysterious and admirable.

　　 There is only one set of samples, which are very precious. They have to be reassembled for engine testing and must not be destroyed.

The dozens of people in the surveying and mapping design team are contracted by the branch workshop and set up more than a dozen professional groups such as turbines, compressor shafts, disks, blades, combustion chambers, flame tubes, receivers, tail nozzles, and complete sets of finished parts, respectively. Parts.

　　The metallurgical and chemical team is responsible for analyzing and testing various metal and non-metal materials, researching heat treatment and performance treatment processes.

　　In this way, it took more than a year to complete the surveying and mapping of the modified turbofan engine and the compilation of all technical data.

　　 You must know that at that time, in a special period, when most of the industrial and mining enterprises were completely paralyzed, it was a miracle that Yonghong Plant could complete the technical surveying and mapping of turbofan engines under such circumstances.

However, just as the Yonghong Plant was preparing to prepare materials for the next specific development of turbofan engines in accordance with the technical data, the central ministries and commissions at that time issued the task of developing large passenger aircraft to City H. Ten" project.

　　 The project was commanded and coordinated by the central ministries and commissions. 262 enterprises and units from 21 provinces and cities across the country participated in the development, and the H City Aircraft Company was established, directly under the leadership of H City.

　　Ren Yongxiang, the deputy head of the surveying and mapping design team and the chief engineer of Yonghong Factory, received an emergency dispatch order from the ministry, asking him to rush to City H to participate in the development of the "Yunshi" project. UU reading www.uukanshu.com

The high-power turbofan engine regarded as a treasure by the Yonghong factory was also urgently set off from the railway freight station in the factory, together with the parts drawings obtained from surveying and mapping, tooling drawings, metallurgy, process, general assembly and other tens of thousands of documents. To H city.

The results of the Yonghong factory after a year of busy work were taken away so hard. Not to mention, the chief engineer of the technical core was also poached away, saying that it was a chicken fly, and the wife was paid a discount. Soldiers cannot be overstated.

This incident has dealt a great blow to the Yonghong factory. Many people were disheartened and transferred from the Yonghong factory. From then on, the cadres and employees were not interested in research and research, and felt that even if they did it, they would make wedding clothes for others, so why not please .

　　These emotions abound in the meeting minutes later. Although the writing is rather obscure, Zhuang Jianye can still feel the grievance and resentment between the lines.

　　 "Perhaps this is the reason why the factory is thinking about transforming civilian products."

　　 Close the file, and Zhuang Jianye sighed. He vaguely understands the reason why Yonghong Factory has not become a "Speey" turbofan engine manufacturer. It is estimated that it is similar to the situation of large aircraft, but there is no such detailed record to confirm it.

To be honest, I would feel uncomfortable about who was picking the peaches on the stall, including his Zhuang Jianye. Because of this, Zhuang Jianye put down the meeting minutes and continued to search in the file cabinet No. 17, not for anything else, just to be able to Find some data left over from the beginning.

　　 Even if they can’t take on the heavy responsibility of a big airplane, let people know that the ancestors of Yonghong Factory have fought, worked hard, and fought hard to make airplanes. Even if they are excluded later, their contribution will not be wiped out.

　　 I can't be the master involved in the development of large aircraft, but I still have the ability to show these files to the world.
