Chapter 527, Skeleton Installation
"I have to say, this Eagle Sauce still has some unique skills, you see that our aircraft uses the Eagle Sauce installation method, the surface of this aircraft looks much smoother, and the parts in it are also standardized parts, so it is relatively simple to maintain."
Hearing someone talking, Jiang Yan, who was watching the Xinzhan-6 aircraft in the hangar, turned around and saw Mr. Xu coming from the door of the hangar.
It turned out that after the "rotation and promotion" was written out by Jiang Yan, Mr. Xu reported to the superior as an internal reference, and the superior felt that this set of plans was more suitable for China's national conditions than the assembly line proposed by Jiang Yan before, and soon the superior had important instructions, so that Jiang Yan could promote it in the entire Shengjing Aircraft Factory.
Therefore, Jiang Yan and Mr. Xu studied how to improve the Xinzh-6 aircraft together with these researchers, and also took into account the promotion of the set of "rotation and promotion" system he designed.
Due to the mainstream of apprenticeship is still popular in the factory, this is when the master teaches his apprentices, almost no other workers are allowed to visit, which leads to the fact that a large part of the master knows that the workers can only rely on their own exploration, resulting in the improvement of their own work level is quite slow.
After Jiang Yan proposed this system of "job rotation and promotion", a large number of training courses and tutorial classes were opened at the same time, so that many hard-working workers saw hope, so that these classes were full every time.
Jiang Yan also organized a group of senior workers and technical experts to compile an operation manual for the situation of the Shengjing Aircraft Factory.
This has led to the fact that in the promotion of this small half a year, the atmosphere of learning in the entire Shengjing Aircraft Factory is unprecedentedly strong, and a large number of workers have upgraded their work levels, which makes these workers feel a lot better for Jiang Yan, the person who proposed the system of "rotation and promotion", no matter where Jiang Yan goes in the factory, there are people who greet him quite warmly, so Jiang Yan's prestige in the eyes of these people is quite high.
Since the implementation of the system of "rotation and promotion", batches of qualified parts have begun to be produced, and the output has increased by almost 30 percent, which makes the leaders of Shengjing Aircraft Factory happy.
Didn't add a machine, didn't add a worker, this output also increased, this is a proper performance, and this performance all the leaders in the entire Shengjing Aircraft Factory have benefited, their sense of Jiang Yan is even better, everyone feels that Jiang Yan is a deputy general.
Jiang Yan not only promoted the system of "rotation and removal" in Shengjing Aircraft Factory, but also promoted the assembly method of the aircraft that was assembled by Eagle Sauce in the later generations based on the skeleton, and the assembly method of accurately positioning the skeleton of the fighter and assembling the skin, which made this batch of produced aircraft look more than one grade higher in appearance, and it no longer looked wrinkled, but extremely smooth on the outside.
It is also not easy to promote this skeleton-based installation method of the West and Eagle Sauce.
It is important to know that aircraft assembly is the process of positioning and connecting a large number of parts according to the drawings, which is one of the important links in aircraft manufacturing, and its workload accounts for about half of the entire aircraft manufacturing labor workload. In the process of aircraft assembly, it is necessary to use a specific tooling frame to ensure the assembly accuracy, and due to the difference in the aerodynamic shape of the aircraft, the frame is unique.
Moreover, in the assembly, Jiang Yan also found that the most difficult thing is the fastener connection between the skin and the skeleton. In manufacturing, Jiang Yan found that in order to ensure the accuracy of the aircraft's shape, the main strategy is to control the accuracy of the hole-making, countersinking, and countersinking process. However, once the accuracy of the countersink connection process is insufficient, it will lead to the inconsistency of the upper end face of the rivet and the surface topography of the aircraft, which will cause irreparable damage to the shape accuracy of the aircraft. However, due to the complex surface morphology of the aircraft, the large-scale application of composite materials of the aircraft fuselage, and the inherent lack of local stiffness, it is very difficult to simply control the stacked hole making accuracy of the skin and the wall plate, and the problem of group hole out-of-tolerance often occurs.
Jiang Yan flipped through a large number of materials, combined with the situation on the spot, found that in order to maintain flatness, the core idea is to pre-group the rivets used for connection according to their actual size, and then make holes and countersink between the aircraft skin wall panels, and use high-precision measuring equipment to detect the accuracy of the nest depth. Combined with the rivet grouping information and the measurement results of the socket depth accuracy, the appropriate rivet is selected for connection and fastening, so as to ensure the surface accuracy.
In the assembly project, such problems appear one after another, and Jiang Yan and they solve them one by one, guiding the work during the day, and hiding in their own space at night to query information with the computer. In the case of stumbling and stumbling, and in the case of many technicians' group contributions, the process was finally perfected, and now the finished product produced by this process is in front of us.
"We have successfully glided on the ground today, the superior leaders congratulated us, and the follow-up experimental arrangements will be gradually launched, and if there are no accidents, this warhawk will go to the sky for the final test in half a year." After speaking, Mr. Xu excitedly patted the silver war eagle.
Looking at Mr. Xu's excited appearance, Jiang Yan really didn't want to tell him the news that he was leaving, but Jiang Yan thought about it, and it was better to say.
"Mr. Xu, I'm afraid I won't be able to accompany you to participate in the next experiment."
"What's the matter, is there a new project arranged above? It's okay that this project has me! You can have complete peace of mind. ”
Hearing Mr. Xu's words, Jiang Yan nodded and shook his head again. Then he spoke: "I received a notice from my superiors today, and I will leave Shengjing with my family early the day after tomorrow and return to Sijiu City." ”
"Why did you leave Shengjing, why was it so sudden?" After Mr. Xu said this, he suddenly thought of something, his face changed, and then he spoke.
"Is there someone who is going to come and pick peaches? Tell me, who is he, are you afraid of offending me, I will react to the leader, and the leader will not care if I react to a higher level. “
Listening to his unhappy tone, Jiang Yan said that he didn't dare to move, it was fake, but this thing was really not what he thought.
"No one picks peaches, the project of the fifth master of the chief engineer has been restarted, and the imitation of high-precision machine tools must also be carried out simultaneously, at present, all the scientific researchers have been in place, and I am still busy with our new war-6 project, the project has been taken and landed, I can't help much here, and the superior told me to go back."
"Really?" Mr. Xu asked.
"Really, don't you know that?" Jiang Yan asked again suspiciously.
"The family knows the situation now!" Mr. Xu then asked.
"I know, today I asked my secretary Xiao Gong to inform them. I guess they're still packing up at home at this time! Jiang Yan said.
"Okay! Since the superior has arranged it, pay attention to safety on the way back, call me if you need to, and come to Shengjing to have a look if you are fine," Mr. Xu then spoke.
"Don't worry! I understand. Jiang Yan nodded and said.
Seeing the back of Jiang Yan leaving, Mr. Xu stood there and watched for a long time, he thought about it at the door of the hangar, turned around and walked in the direction of the factory director's office building.
