Chapter 237 Secondment ends, return to the institute
When one project progresses smoothly, driven by a good mood, the next project will be accelerated a lot.
Three weapons: 107mm towed rocket launcher, 122mm towed howitzer, and 155mm towed howitzer.
Within three months, the experimental sites were successively moved.
The 107mm towed rocket launcher has actually been around for a long time. It has been around for more than 60 years, but the maximum range at that time was only 8,500 meters.
Zhang Yu's improvements this time extended directly to meters, and on the original basis, the firepower was once again improved.
The 122mm towed howitzer also existed in the 1960s and was equipped in large quantities.
This one designed by Zhang Yu is a 122mm towed howitzer from 1983.
155mm plus howitzer, the full name is W88 type 155mm plus howitzer.
The barrel of this gun is integrally forged from electroslag re-melted gun steel and is self-tightening; the breech block is a semi-automatic screw-shut type; the muzzle brake is a three-chamber cylindrical type; the anti-recoil device is a liquid-pneumatic type.
It is composed of a retraction machine and a retraction machine, with variable recoil, and the recoil length changes with the shooting angle.
It is also a product from ten years later, the crystallization of designers in 1987.
It is also the most difficult to develop among the three types of artillery.
Because in the past ten years or so, the level of science and technology has undergone earth-shaking changes.
In the early 1970s, after more than ten years of developing artillery, one can imagine the difficulties involved.
But as long as there are design drawings, nothing is impossible.
The first two types of artillery can be said to be upgraded. The W88 155mm plus howitzer can be said to be created from scratch.
From the beginning of development, to the completion of product technical identification, and then to the collection of various data indicators.
Putting it all together, it has spanned an autumn. When the upper management decided to mass-produce, it had already entered the twelfth lunar month of winter.
Zhang Yu's secondment finally came to an end and he returned to the research institute.
Quickly invest in the research and development of diesel engines.
Here, Zhang Yu's work is not so busy. Chief Engineer Xu takes the lead in design, and Zhang Yu's job is only responsible for production experiments.
"Zhang Yu, the Chinese New Year is coming soon, and the institute plans to implement a rotation system. When do you plan to take a break?"
General Manager Xu found Zhang Yu and informed Zhang Yu of the rest time arranged by the office.
"XCMG, how many days do we have on this rotation?"
"Take three days off, because we consider that the Chinese New Year is a day of reunion, and it takes time to visit relatives and friends."
"So, the director decided to let us look at the arrangements and specify the specific time off so that the director can arrange shifts for everyone."
Zhang Yu nodded understandingly, but this needed to be considered, so Zhang Yu was not in a hurry to reply.
"Oh, okay, let me think about it and report it to you when I get off work in the afternoon."
"Okay, then you get busy first, and we'll decide when we get off work."
"By the way, the Artillery Bureau has taken your last month's salary and kept it in the finance department."
"When you have time, go to the finance department to get it."
"Hey! OK, I'll go when I have time."
Mr. Xu thought for a while and had nothing to say, so he turned around and went to inform others.
Zhang Yu left the artillery bureau in a hurry. The next day after finishing his work, he went directly back to the station.
Therefore, Zhang Yu didn't have time to collect the last month's salary. Now the Artillery Bureau has delivered it to the station, which saves Zhang Yu one more trip.
When the get off work bell rang, Zhang Yu told the masters and came to Mr. Xu’s office.
"Xugong, I've thought about it. I plan to take three days off from the first to the third day of junior high school. Is it okay?"
"Okay, don't worry about the rest. I'll register you in a moment. You can go home quickly!"
"Okay, thank you Xugong, I'll leave first."
"Well, let's go, let's go."
Xugong waved to Zhang Yu.
The reason Zhang Yu chose these three days was because he planned to accompany Mengyi and her children back to his mother-in-law’s house for a reunion dinner on New Year’s Eve.
The next day, the two of them were riding their bikes early in the morning, taking their children back to the countryside.
On New Year's Eve, the old man would go down the mountain and go to Zhang Yu's house for a reunion dinner. On the first day of the new year, the old man happened to be there, so I just wanted to wish him a happy new year.
Then we go around the village and say New Year’s greetings to our close uncles, aunts, and friends.
After lunch on the second day of the Lunar New Year, I went back to the city, went to Uncle Xu’s house to pay New Year greetings, and then went to the master’s house to pay New Year greetings and have a drink with the master by the way.
On the third day of the Lunar New Year, I went to the homes of Dean Zhao and Dean Wang to pay New Year greetings. I played with the children all afternoon, and then went to work on the fourth day of the Lunar New Year.
After returning home, Zhang Yu told Mengyi about the time he had arranged, and Mengyi thought there was no problem.
Just like that, as we entered the last week of the twelfth lunar month, people in the institute began to take turns taking turns.
By the time New Year's Eve arrived, there were not many people left in the institute, and even the director had taken turns to take the day off.
Stay up until get off work, go to the finance department, and collect this month's salary together with the salary sent by the Artillery Bureau.
I rode my bike directly to my mother-in-law’s house.
As soon as I entered the door, I saw Mengxue leading three children playing with wooden figures.
As soon as Mengxue turned around, she saw Zhang Yu pushing a car in.
"Brother-in-law, you are back."
"Well, I'm back."
The three little guys quickly turned their heads and took a look.
"Dad!"
The three little guys swarmed up, regardless of whether the car was put away or not. Nuannuan and Xinxin occupied the whole day alone.
The puppy behind was jumping anxiously.
"I want to hug daddy too, I want to hug daddy too."
"Okay, okay, let's wait until dad puts the car away."
"Nuan Nuan Xinxin, can you two give way first and let dad put the car away?"
"Oh! Okay."
The little sister reluctantly let go of her father's lap.
Zhang Yu pushed the car into the west room and went out to hug the children one by one.
"Did you obey me at grandma's house today?"
Nuannuan spoke first.
"Yes, we are obedient. Grandma is teaching us how to write."
Zhang Yu was a little surprised.
"Hey, I've been writing today. What did I write about?"
"We wrote our names, and grandma even praised us for how well we wrote them."
Xinxin immediately raised her hand and said.
"Really? Not bad, they are indeed daddy's babies."
"Come on, let's go into the house. Dad feels a little cold."
"Okay, let's go inside!"
The children surrounded Zhang Yu and returned to the house.
Little Dog Dan stretched out his calves and ran into the house early to report the news to his grandma and grandpa.
"Grandma, grandpa, look, dad is back!"
"Zhang Yu is back."
"Mom and Dad, I'm back."
Zhang Yu looked around and didn't find Mengyi.
"Mom, where's Mengyi? Why don't you see Mengyi?"
"Xiaobai came here in the afternoon and said that we would go to the market to buy some New Year goods together."
"Don't you plan to go home tomorrow? Mengyi went to buy gifts for Lao Zhang and the others."
"At this point, I guess I'll be back soon."
I turned around and glanced at the clock in the room.
