Jiang Yan returned to the design institute and life returned to normal.
Time passed quickly, and in the blink of an eye it was mid-April, and Jiang Yan's design was finally completed.
At a test site in the suburbs, the rail car designed by Jiang Yan was slowly moving towards a high slope in the distance, where several mines were buried. The task of the rail car was to find the mine points, trigger the device with its own weight, and detonate the surrounding mines.
This track-mounted vehicle, which is similar to a modern robot, is indeed novel, and its battery components are very light. The vehicle has two sections of tracks and can climb up and down very flexibly.
Not long after, the car hit the trigger device and exploded directly.
After the explosion, the leaders put down their binoculars, some pondered, some smacked their lips in amazement.
"It's a good thing, but the cost is too high. How can this car be used on the battlefield when it costs so much?"
"That's right. The materials require rare metals and also require precision welding. The technical barriers are much higher than we thought, and it's difficult to achieve mass production."
"Yes, there is also this battery. I think this battery can be used. Master Xu, your disciple is quite good. He has a sharp mind and many ideas."
A group of people came back from the suburbs and held a meeting in the courtyard, mainly to give a comprehensive evaluation of the concept mine-detecting vehicle designed by Jiang Yan.
As the main designer, Jiang Yan did not attend the meeting.
She actually had no idea at all!
She knew the advantages and disadvantages of the car very clearly.
Needless to say, her car has many advantages, from the body material, to welding, to the battery and control body, all of it uses relatively advanced technology inside and out. If it were placed in later generations, it would be just an ordinary gadget, but in this era, it is a big step ahead.
She did this at great risk, with the goal of clearing mines on the battlefield two years later and saving the lives of the soldiers.
The disadvantage is also very clear, that is, the cost is too high.
Given China's current national strength, it is very difficult to mass-produce such mine-detecting vehicles, and mass production is impossible.
The most important thing is that it is a disposable product. After being blown up, it becomes a pile of scrap metal. The investment is too high.
Jiang Yan was very anxious. In fact, it didn’t matter whether this thing could win a prize or become her graduation project. What mattered was saving lives!
In her heart, human life is always more important than anything else.
Sure enough, after the meeting, Mr. Xu brought her good news and bad news.
"Which one do you want to listen to first?"
When Jiang Yan heard him say this, she knew that her car would definitely be put in the warehouse to gather dust. "Teacher, is it because they didn't like my work and it was rejected?"
"Hmm..." Xu Tianlai pondered for a moment, "Half and half."
"What do you mean by half and half?"
"Half of it is bad news, and half of it is good news." Old Xu said seriously, "I guess when you designed it, you thought that this design might be very useful 23 years later, but it is not realistic for us now."
Sure enough, it was just as she thought.
"What about the good news?"
Mr. Xu didn't know whether to cry or laugh, "They like your battery..."
"Oh yeah, and your welding skills. I heard from Long Gong that the four-year workers in their class can't weld as well as you? When did you learn welding?"
Jiang Yan was speechless.
"Just think of me as someone who is good at what I do and a man of talent."
With the big wheel, there is nothing she can't do.
"You don't have to be discouraged. Your little car is really interesting." Seeing that she was not in high spirits, Mr. Xu quickly changed the subject. "I am optimistic about its development and your foresight. But what exactly is your remote control program? Tell me about it when you have time."
"good."
Jiang Yan was indeed not very excited. The purpose of designing the car was to reduce casualties. She wanted to use machinery to replace manual labor and did not want our soldiers to be killed or maimed again.
But she forgot one thing, that is the cost.
At this time, labor is much cheaper than these machines...
She just wanted to use the machines she researched to do some dangerous work and suffer the pain and suffering on behalf of the soldiers.
"It's better than letting them replace humans' means of livelihood, right?"
"What did you say?"
Jiang Yan quickly shook her head, "Nothing, well, teacher, is my graduation project considered finished?"
"Of course it's done. You can just wait to get your diploma. Although your design cannot be mass-produced, the overall level is quite high. It is not just a mechanical concept, but also remote control. Tell me what you think..."
Many times, a great invention or design originates from unrealistic fantasy. Jiang Yan even realized her fantasy. In this sense, she was successful.
"Actually, it's very simple. I just mixed a few books together..."
The master and apprentice chatted in the office for more than an hour.
Finally, Xu Tianlai took off his reading glasses and handed a few pages of draft paper to Jiang Yan, "Write your paper!"
"Um, Master, can I ask for a leave?"
"What's up? How long will it take?"
"Half a month."
Jiang Yan said, "You know, I'm a doctor. I have a patient in the countryside of Northeast China. I've agreed to see him at this time. It's a matter of life and death. Please see."
Whether this fake approval is approved or not depends entirely on Xu Tianlai.
In fact, Jiang Yan's work has been done very well, but fifteen days of vacation is a luxury for a scientific researcher.
But who made Mr. Xu favor his disciple?
His apprentice is in a bad mood and has completed his graduation project. Can't he go out for a walk to adjust his mood?
Besides, they are not going out to relax, they have a mission to accomplish, and they are saving people!
Xu Tianlai made the decision on the spot and approved the leave.
Jiang Yan finally breathed a sigh of relief, went back and packed her things, planning to go to the Northeast.
Ning Yu still remembered that she was going to take the child back to Northeast China, so she asked casually, "Are you still going?"
Jiang Yan had forgotten about this matter originally, but after she said this, he immediately remembered it.
"Go, why not?"
Jiang Yan felt that it would be best if she could take not only her children but also her mother-in-law with her, and have the whole family experience life in the countryside and visit the place where she once lived.
"Mom, you should go too! Otherwise I won't be able to take care of two children. Aunt, do you want to go?"
Si Zhen waved his hand, "I won't go. It's rare for me to have a few days of rest."
Ning Yu became interested, "Why not ask your grandparents if they want to go, and let your aunt and brother go with you to relax. In a few months, your uncle and your father will come to Beijing, and they won't be so free anymore."
yes!
Jiang Yan's eyes lit up. This was a great idea.
