In 1978, I was admitted to Harbin Institute of Technology

Chapter 113: Not bad! Not bad! Just beat the not very flexible Changkong No.

"Let's set out tonight to prepare for the test?"

Xie Wei looked at Lai Guichang with a puzzled look on his face. "Should we follow the procedures and make all the preparations?"

"The preparations have been completed. According to the normal process, it takes several months from reporting to approval to completion of preparations. Currently, we are only verifying some technologies. After the military representative office reported to the superiors, the superiors suggested that we merge the test project with that of Factory 112."

Xie Wei made great contributions to this improvement project, and many of his suggestions benefited the entire team.

In the school missile project team, everyone was very nice to Xie Wei.

Lai Guichang naturally didn't mind helping Xie Wei solve his doubts.

"A test project of Factory 112? A test flight of the J-8?"

Xie Wei was even more confused.

The J-8 has already started its final test flights and will soon be approved by the Aviation Products Committee. It will be approved by the Military Products Finalization Committee next year and its development work will be completed.

Could it be that the air combat capabilities of the J-8 fighter jet have already begun to be tested?

Xie Wei really had no idea what the process was for finalizing the design of fighter jets and missiles, or how to operate it.

"Don't we need to conduct ground testing of the sample bomb?"

Even though he didn't understand the detailed process, Xie Wei had a general idea that the missile test definitely couldn't be done so quickly.

"Ground testing has been ongoing. Although the seeker and internal computer group have been replaced, the weight is based on the previous warhead weight. We will test it directly and discuss other things if it works..."

Lai Guichang said.

He also couldn't explain to Xie Wei that the Air Force was eager to get missiles with higher hit rates.

The PL-2 air-to-air missiles already in service in the military have a short range and a very low hit rate.

The relevant leaders suggested that they first test whether replacing lead sulfide with indium antimonide and redesigning the computer system could solve the problem of passive infrared guided missiles missing their targets.

It is effective. Not only can the performance of the air-to-air missile models under development be improved, but the progress can also be accelerated.

"You haven't had a good rest recently. Go back and take some rest and visit your sister. We can't spend the New Year at school."

Lai Guichang changed the subject and asked Xie Wei to go and fix it.

Xie Wei scratched his messy hair, which was like a chicken coop, and felt that it was time for a haircut.

I haven't taken a shower for a long time.

After several months in Harbin, Xie Wei still couldn't accept that everyone had to stand naked under the faucet to take a bath, or soak in the big bathhouse together naked.

Fortunately, the school dormitory building has heating.

Xie Wei would often take a bath in the washroom in an enamel basin while wearing his shorts when no one was around, and then take off his shorts after washing.

After tidying up and changing his underwear, Xie Wei went to the school barber shop to get his hair cut. The originally haggard Xie Wei became energetic again.

Then he ran to the grocery store and bought two cans of yellow peaches for Xie Rou.

"what happened?"

When Xie Wei arrived at Du Guowang's house, Xie Rou was not studying. She was lying on the bed dying with lifeless eyes.

Xie Wei was frightened by Xie Rou's condition. He hurriedly touched Xie Rou's forehead with the back of his hand and found that she did not have a fever.

"Brother, I'm going to die..."

"Bah! Bah! Bah!"

Xie Wei quickly spat, "It's New Year's Day, why are you saying something unlucky? What's wrong with you?"

Since Xie Rou came to Du Guowang's house, she has rarely moved around. Except for going to the toilet, she eats on the kang. Her originally oval face has become fat and round.

I'm healthy!
She actually told herself at this moment that she was going to die.

"Really, brother, I'm really going to die... My stomach hurts, and I'm bleeding... Brother, I don't want to die in the Northeast, please take me back... No, I can't go back, Mom will be sad..."

Xie Rou stared at the roof with a dull look and spoke weakly.

No panic, no other emotions.

"what?"

Xie Wei was dumbfounded.

After being stunned for a while, I realized that it seemed that Xie Rou had entered her menstrual period.

Didn’t I tell her how to deal with it?
Liang Hongling probably didn't have the time to explain these things to Xie Rou in normal times.

There is no such content in biology books...

"Brother, where are you going? I'm going to die..."

Seeing Xie Wei turning around and preparing to leave, Xie Rou hurriedly called him, hoping that Xie Wei would stay with her.

"What the hell! I don't know how you studied biology. It's your period. Wait a minute, I'll find someone to help you."

Xie Wei said unhappily.

Even though I came here decades later, I couldn't teach Xie Rou about menstruation because it involves privacy. I didn't know how to start the conversation.

This knowledge should definitely be better taught to girls by women.

"Monitor, what's wrong?"

Xie Wei ran to the radio laboratory panting and called Mo Lingyu out.

"Well, I want to ask you for a favor..."

Looking at Mo Lingyu, Xie Wei felt a little embarrassed and didn't know how to start.

He had no idea about the situation of personal hygiene products for women these days. When a grown man went to a department store to inquire about them, he would be taken to the police station by the tough female salesperson and charged with hooliganism.

"Just tell me what you want to say. I'm busy!"

Seeing that Xie Wei was embarrassed, Mo Lingyu no longer had the infatuated look she had when they were alone together before. Xie Wei took her to the radio project and ran away.

"Well, Xie Rou seems to have her period. She has no experience, so I don't know..."

"Ah? Thank you, second sister?"

Finally knowing why Xie Wei was so shy, Mo Lingyu immediately understood, "Wait for me at the school gate, I'll go back to the dormitory..."

"Let's go."

After a while, Mo Lingyu came out of the dormitory and urged Xie Wei to take her to find Xie Rou, "Didn't Second Sister Xie go back home for the New Year? I thought she went back."

On the way to Du Guowang's house, Mo Lingyu took the initiative to find a topic to ask Xie Wei.

"Originally, my dad planned to let me bring her back home when I go back home during the holidays. Aren't all the classmates in my class busy with projects..."

Xie Wei explained.

"Oh, monitor, what are your plans for the New Year? How about we organize the whole class to make dumplings?"

As Mo Lingyu walked, he turned his head to look at Xie Wei.

As a result, his foot slipped and he almost stumbled and fell.

Fortunately, Xie Wei was quick enough to pull her arm, but even so, her body swayed several times before she could stand steady.

We all wore heavy military coats in the winter, so there was nothing awkward about it.

"You have to go out with the school teacher tonight and won't be back until after the New Year. If the school doesn't organize any activities, you and the class leaders can organize some activities with your classmates."

"Ah? Going out during the New Year?"

Mo Lingyu stared at Xie Wei with eyes wide open, "Don't other units celebrate the New Year?"

Xie Wei looked at her, smiled, and said nothing.

Mo Lingyu didn't ask any more questions.

The originally harmonious conversation came to an abrupt end, and the two walked silently towards Du Guowang's house. The further Xie Wei walked, the more he felt something was wrong.

Liang Hongling probably didn't prepare any personal hygiene products for Xie Rou, right?
He felt that he should remind Mo Lingyu.

"Don't you go to the department store to buy sanitary napkins?"

"Sanitary napkin? What sanitary napkin?"

Mo Lingyu asked Xie Wei in confusion, and as soon as he asked, he realized the problem and his cheeks were instantly covered with red clouds.

"Hygiene Sutra, then...what do you usually use during your period?"

For a moment, Xie Wei didn't know how to explain. It was impossible for the department store not to sell this thing, but he didn't dare to ask in this era.

Will be beaten to death!

"Squad leader, how dare you act like a hooligan!"

Mo Lingyu, blushing, glared at Xie Wei in anger, "If you do this again, I'll go back!"

Although he knew that Xie Wei didn't mean it, didn't the monitor know that it was presumptuous to talk about such private matters with a girl?

Isn't that very rude?

"..."

Seeing Mo Lingyu's reaction, Xie Wei immediately realized the problem and explained awkwardly: "I am worried..."

"I just went back to get something."

Thinking that Xie Wei was also worried about his sister, Mo Lingyu didn't care about it anymore.

The two continued walking forward awkwardly.

Fortunately, we had already arrived outside Du Guowang’s small yard.

"Go to the kitchen and help boil some water. See if there is any brown sugar. Make some brown sugar water for Xie Rou to drink..."

Mo Lingyu entered the room and saw Xie Wei preparing to follow him in. He rolled his eyes at him unhappily and gave Xie Wei a stern look.

Who is he!
As a grown man, doesn't he want to avoid suspicion?

Xie Wei awkwardly followed Mo Lingyu's instructions to make brown sugar water.

"Okay, it's no big deal."

When Xie Wei boiled the brown sugar water, Mo Lingyu had already explained to Xie Rou all the things that should be paid attention to.

At this moment, Xie Rou no longer had the look of despair she had before, which made Xie Wei feel much more relieved.

I wanted to ask some more questions, especially related to health.

Xie Wei thinks sanitary napkins are a good thing that can easily make money. If they are not available on the market, they can be directly developed to make money; if they are already available on the market, they can provide improvement plans, improve the process, etc., so as to gain a larger market share. Women's money is the easiest to make, this is the basic principle.

However, since both Mo Lingyu and Xie Rou were very evasive, he ended up not asking.

"Xie Wei, are you done with your work and have a holiday?"

Just as Mo Lingyu was about to say goodbye and go back, Liang Hongling came back and saw Xie Wei first.

After asking, I saw Mo Lingyu, who smiled and greeted: "Xiao Mo is here too?"

"Teacher Liang, I..."

"Godmother, I'm a big girl now!"

At this moment, Xie Rou no longer had the hopeless state she had when Xie Wei came before.

"what?"

Liang Hongling was stunned.

Mo Lingyu glanced at Xie Wei with dissatisfaction. Helplessly, Xie Wei could only go out and wait for Mo Lingyu to report Xie Rou's matter to Liang Hongling.

After a while, Xie Wei raised his wrist and saw that the time for departure was approaching.

He said directly to the people who were still whispering in the yard: "Teacher Liang, I'm going out with Professor Lai and the others. I won't be back for the New Year..."

"Go."

Liang Hongling didn't hesitate at all.

To her, although Xie Wei's talent might be stronger than Xie Rou's, Xie Wei did not study mathematics. Didn't he see that Xie Rou had been immersed in various difficult mathematics every day since she came here?
What's more, Xie Rou calls her godmother.

Now that I have something better, I will naturally stop focusing on Xie Wei.

Xie Wei didn't say anything and just turned and left.

"Godmother, the New Year is coming soon..."

Without the worry of death, Xie Rou thought about the lively scenes of the family celebrating the New Year together every year, and said sadly, "My brother is leaving, and I will have less New Year money. Since my brother started working, he has given me five yuan every year!"

"..."

Looking at Xie Rou, Liang Hongling and Mo Lingyu were both stunned for a while.

It seems that this girl is not upset because her brother can't spend the New Year with her.

One less New Year’s money!

five yuan!
The relationship between brother and sister is only worth this much.

"Don't worry, you still have your godmother and godfather! And by then, you'll also have your uncle and the others. Godmother promises that you'll have more than you had before!"

"Second sister, you don't spend money, why do you need so much money?"

Mo Lingyu has already learned that since Xie Rou entered Du Guowang's house, she has never gone out, let alone bought anything.

In an era when everything required tickets, you couldn't buy much even if you had money but no tickets.

"My brother said that experiments cost money, and I have to raise money for future experiments..."

Xie Rou answered seriously.

"..."

But both of them didn't know how to respond.

Save money to conduct experiments?
Maybe this is the difference between geniuses and ordinary people.

"Teacher Liang, Xie Wei is out during the Chinese New Year. Don't other units celebrate the Chinese New Year?"

Mo Lingyu was very curious about what Xie Wei was going to do, but due to the confidentiality rules, he couldn't ask directly.

"Don't ask around, it's confidential."

Liang Hongling reminded Mo Lingyu that she liked students with good grades.

Mo Lingyu was the second in the experimental class, and because he had helped solve Xie Rou's menstrual problems before she came back, he treated Mo Lingyu better. "Many people in the experimental class will enter these projects later. You have to learn to suppress your curiosity... By the way, the school will start selecting students to study abroad after the new year. What do you think?"

Liang Hongling's words stunned Mo Lingyu.

Going abroad?

Before this, Mo Lingyu had never thought about it at all.

······
"Hurry up, I'm waiting for you."

When Xie Wei rushed back to school, night had already fallen.

The two sample bombs had been packaged and loaded into the cargo box of a tarpaulin-covered Jiefang truck.

When Lai Guichang saw Xie Wei appear, he hurriedly invited him to get in the car.

"The troops are coming so quickly?"

Xie Wei saw several soldiers with guns standing next to the truck, but he couldn't tell what kind of troops they were.

There are definitely no soldiers in the school.

In particular, these soldiers were holding Type 63 automatic rifles with wooden stocks and folding bayonets, and had belts around their waists filled with magazines.

It's not a 56 semi-automatic, nor a 56 submachine gun.

It should be from an elite force.

"The military representative office has arranged for you to get on the jeep in front. We are running out of time. There are dry food and water in the jeep. Make do with it. When we get to the destination, you can eat something hot."

Seeing that Xie Wei was wrapped in a military coat, Lai Guichang directly urged Xie Wei to get in the car.

As soon as Xie Wei got on the back seat of the jeep, he saw Yu Guofeng and Shi Hongwei already sitting in the back seat.

The person driving in front was also a soldier, so it was difficult to greet him.

As soon as I sat down, the jeep started.

Taking advantage of the night, we drove directly outside the school.

"Professor Shi, aren't trains faster?"

Lai Guichang has already said that it will be merged with the fighter jet testing of Factory 112.

From Harbin to Shenyang, the journey by rail is definitely shorter than by road, and it is less painful.

"There is no train service to the place we are going to. Time is tight and the task is heavy. We need to arrive early and make preparations. It's still early now, so let's get some sleep."

Shi Hongwei explained to Xie Wei.

The car drove all night.

The next morning, the surroundings began to become remote. Xie Wei was not familiar with the terrain of the Northeast, so naturally he had no idea where he was.

There are no highways and no road signs.

For those who are not familiar with the surrounding environment, they have no idea where they are in such a deserted place.

Except for occasionally stopping to let everyone move around and go to the toilet, we kept driving the entire time. The driver of the 212 jeep was even changed halfway through, and it was not known whether he was from a Jiefang car or another 212 jeep.

The jeep that Xie Wei and his companions were in was always in the middle, with a 212 jeep leading the way in front, followed by a Liberation truck loaded with sample ammunition, and behind that, there was another Liberation truck carrying fully armed soldiers.

In that car, not only were all the soldiers equipped with Type 63 rifles, but Xie Wei also saw several soldiers carrying rocket launchers when they set out, and there was even a squad machine gun!
As for what!
But he was too lazy to ask.

There was no answer even if I asked. Yu Guofeng and his companions knew the answer but they wouldn't tell me. The troops wouldn't answer me either.

The convoy was driving along, and Xie Wei had no idea in which direction it was heading. There was ice and snow all around, and he rarely saw people since the afternoon. It was not until it was almost dark that he entered a simple one-story building behind a hill.

"arrive?"

Xie Wei, whose bones were almost falling apart, was shocked when he saw the building in front of him.

"Professor Lai, thank you for your hard work along the way."

A cadre wearing a shirt with four pockets came with a few people to welcome everyone in the car.

"You are the ones who have worked so hard. If it weren't for us, everyone would have a good New Year."

Lai Guichang exchanged greetings with the cadres in charge.

Soon, soldiers led the convoy to a warehouse not far away.

Xie Wei and his companions waited until the convoy stopped at the warehouse before getting out of the car.

"J-7?"

Seeing the fighter jet parked on one side of the warehouse, Xie Wei recognized at a glance that the fighter jet was not a J-8, but a J-7.

Both have nose air intakes. The simplest difference is that the J-7 is single-engine and the J-8 is twin-engine.

"Yes, J-7. This J-7 is used for testing the 204 radar... Advanced missiles need to be used with advanced radars. The 204 radar has basically met the design specifications, but there has been no opportunity for further testing..."

The cadre who had greeted Lai Guichang earlier got out of the jeep next to them and explained to Xie Wei with a smile.

"This is an infrared guided missile..."

"If the search distance is longer, the tracking distance is longer, and the missiles are reliable, it is entirely possible to launch missiles at a longer distance."

The cadre said with a smile.

"Everyone, check the missile immediately and make final preparations before the target test!"

Lai Guichang greeted everyone.

what?
Xie Wei was stunned again.

Are we going to start night target shooting right away?
"The infrared special forces are more obvious at night. Tomorrow is the Chinese New Year. The troops believe in the technical strength of the school... For this reason, the base has specially obtained two Changkong-1 remote-controlled drones to test the performance of the improved missiles. Here, that's it."

When the person in charge introduced it, he pointed to a large red drone placed on a launch vehicle not far from the warehouse and gestured to Xie Wei and others.

Changkong-1!
The Air Force has spent a lot of money on this.

Changkong-1 is a large jet-powered radio-controlled high-subsonic UAV, mainly used for missile target practice and air defense force training.

It is a copy of the La-17, but it has been improved. The engine uses the J-6's turbojet-6 engine, with a maximum flight altitude of 18000 meters, a maximum speed of 910 kilometers per hour, and a maximum take-off mass of 2500 kilograms. The 600 kilograms of fuel carried on board can allow the target aircraft to stay in the air at medium and high altitudes for 45 to 60 minutes!

85 seconds after takeoff, the aircraft is switched to onboard program control and can receive ground radio instructions to change the flight trajectory.

"It's okay! It's okay! It's just Changkong-1."

When Xie Wei saw Changkong No. 1, he remembered this target aircraft that the Air Force had used for target practice for many years, and he couldn't help but breathe a sigh of relief.

I’m just afraid of coming up with a more advanced and flexible target drone.
