Xu Ziling's words were half-concealed, and Zhang Lao knew that there must be something in the Dao that outsiders could not know, so he didn't ask how the two of them met, but asked what was the difference between the space-based weapons of the Mi people and their own.

Xu Ziling smiled helplessly, "You have this old question, it can be regarded as stumped for me, we don't know what their specific performance is, the only one that is clear, as I said just now, is that the volume is larger than ours." ”

"How much bigger?"

"More than ten times."

"Ah...... A few hundred tons? How did they get to heaven? ”

……

Space-based weapons,In fact, it is an enlarged version of the laser emitter on the laser car that was made before,The same working principle,But the volume is enlarged,The range is also far,In addition,It is to add a satellite relay station,Used to control after entering the sky。

It is worth mentioning that the satellite body this time is also produced by the military factory itself.

Unlike the space-based weapons of the Mi people, Xu Ziling and the others are not so rich, and it is impossible to make ten or eight of them to be launched into the sky like Lao Mi, so they can only find a way to change the orbit technique.

Orbit change, from the current technical level, is definitely a money-burning job, domestic, a orbit change, the cost will exceed 100 million, such an expensive price, but it is not casual to control the satellite to implement orbit change.

In the early stage, Xu Ziling and the others only had the plan to launch a space-based weapon, but if they wanted to cover the whole world, they could only rely on orbit change.

In this case, the advanced orbit change technique was born.

In the past, the fuel originally stored by the satellite was used to change orbit, but because the satellite is in the sky, the fuel cannot be added after it is added to the ground, so it leads to the high cost of satellite orbit change.

Considering this problem, Xu Ziling finally did not use solid fuel on the satellite, but used an electric thruster and a rechargeable large high-compression battery, which is an enlarged version of the high-energy battery used on the laser weapon.

This battery, in normal times, can maintain the operation of the computer on the satellite itself, and when it wants to change orbit, it can be used to provide energy for the electric thrusters on the satellite.

The battery is charged by two solar panels, which can be used repeatedly, and the charging life can reach tens of millions of times, even if it is charged once a day, it is estimated that it is a little difficult to use it in a lifetime.

"This orbit change technique, are you going to give it to the Great Wall Company?" After taking a look inside the space-based weapons workshop, Zhang Lao asked Xu Ziling.

This kind of battery technology is not only limited to the use of aerospace, but also some large-scale military and civilian products, can be used, although the cost is a little expensive, but compared with some high-precision equipment that costs hundreds of millions of yuan, this is absolutely bearable, so this technology is definitely promising.

There had been an agreement with the Great Wall Company before the cooperation, but the satellite main technology of space-based weapons was not included, but the two sides had cooperated on this project, and it was not surprising that they knew about it.

This kind of technique is what they covet, so after knowing the Dao, they will send someone to discuss whether there is a possibility of authorization or transfer of this derailment technique.

"What they want is a full set of techniques, including battery techniques. But this battery technology, can be regarded as our core technology, I didn't think to give it to them, look at the results of this negotiation, my idea is that the orbit change technology can be given to them, but the battery can only be provided by us, if you can't negotiate, forget it......"

This is a world where technique is king, and technique is the most important, the highest-end field they focus on, those that are not too important can be discarded, but the core technique is definitely impossible to flow out.

If the Great Wall Company relies on the identity of a state-owned enterprise and wants to come hard, it will only result in two shots.

"Well, I don't recommend that the core technique flow out of the ......, the best thing is to keep it in your own hands," Zhang Lao nodded.

After getting off the plane, the time was not early, and in the workshop, Xu Ziling and they didn't stay long.

When Yang Kaiming came back from this trip, Liu Yiyi did not accompany him, Xu Ziling simply called him back to eat together, and drove back to the house, and his parents had already made the meal.

"Hurry up and wash your hands and eat, there must be no good food on the plane." Li Mingwu forgot his son when he had a grandson, but Zhang Lan forgot his son when he had a daughter-in-law.

As soon as Xu Ziling and the others put down their things when they entered the door, Zhang Lan pulled Yang Ruolan to wash, but as for Xu Ziling, they didn't even look at it.

With such a scene, Xu Ziling naturally felt Li Cheng's discomfort before, and smiled helplessly at Yang Kaiming, "Now I have become superfluous at home......"

Yang Ruolan is Yang Kaiming's younger sister, so naturally it is difficult to accept this sentence, but Xu Haoran happened to hear it next to him, and slapped Xu Ziling on the head, "You talk a lot of nonsense, do you want Lao Tzu and me to serve you......"

……

After eating, I was going to take a little rest and then go to the military region, Zhang Lan took Yang Ruolan to sit in the small garden to chat, and Xu Ziling and the three big men were swallowing clouds and fog in the living room.

"What are you going to do with that big guy?" Xu Haoran asked his son.

Xu Ziling thought for a while: "Let's take air transportation, this thing is not too big, a Y-8 can be done, and land transportation is too slow." ”

"Test before you can take off?"

"Well, you must test it once before launching, otherwise, if you don't use it, it will be troublesome to recycle."

"Then tell me when you go over, and I'll go and see it too."

“…… How did you remember to go together? ”

"What? I can't just go and see it? ”

"Yes, why not?"

Unexpectedly, Xu Haoran proposed to go out with his son for the first time, so Xu Ziling was very surprised.

In the military factory, deal with the daily management work every day, when there is nothing to do, go to the shooting range to shoot two shots, or have a confrontation with the security personnel, and at night he either goes home early, or has a few drinks with Uncle Zhao and Zhao Zihua.

At this time, he actually said that he wanted to go and see it together, Xu Ziling was not surprised.

But the father spoke, of course, the son didn't want to ask much, and after being surprised, he immediately agreed.

"I'll contact the transport plane tomorrow, I still have two classes at HKUST, and I should be able to go over the afternoon the day after tomorrow, you can arrange it."

"Hmm." Xu Haoran nodded, "By the way, Shen Fei's prototype is coming out, and he originally wanted me to go over and have a look, but since you're back, then go over together." ”

"Row ......"

Shen Fei's large aircraft project, at the same time carried out two prototypes of passenger aircraft and transport aircraft, this matter is also Xu Ziling has always been more concerned, these days a little busy, did not care about those reports, but according to calculations, he also knew that the road should be about the same, so it is not unexpected.

After chatting for a while, it was past nine o'clock, and seeing that the time was not too early, they were ready to go to the military region.

The distance is not far, and when I go out from home, it will be half past nine when I arrive at the military region.

Zhao Xueqin and Yang Haisheng didn't say much to them, only chatted a few words about the current situation, and then asked them to go to rest early.

The next day was a weekday, so everyone woke up early.

After breakfast, Yang Haisheng and Zhao Xueqin's respective drivers came to pick them up, and Xu Ziling and the three of them were left in the house.

Xu Ziling contacted Master Lin and asked him to help arrange a transport plane.

"Yun-8, yes, no problem, the old rules, I'll arrange it for you, and you pay for it yourself." Master Lin readily agreed to him.

"Thank you...... Thank...... I immediately had things boxed up and sent them over. ”

The matter was resolved, and the two talked about Lin Jianbin again, not to mention that Lin Jianbin was doing well in Makula, but with their relationship, of course Xu Ziling would not say those bad things in front of Master Lin, so as not to worry the elders.

"Uncle Lin, don't worry, if it goes on like this, it is estimated that it will not be long before you have to prepare to accept your daughter-in-law."

"Really? Ha Lu Ha ......"

……

After determining the transport plane, he immediately called his father Xu Haoran and asked him to arrange for someone to start loading the "space-based weapons" into the truck, "I have booked the time for Lu to take off tonight, don't worry after getting it done, and send it over when it gets dark." ”

"Okay, I've got it."

The three of them were too lazy to cook, thinking about going out to eat, and they didn't want to make a big fuss, and finally thought of Li Cheng, Aunt Zhou went to Li Cheng's side yesterday afternoon because of her grandson's return, so several people decided to go to Li Cheng's house to eat.

drove over, not only Aunt Zhou was there, but Li Cheng's mother also asked for leave at home, but Li Mingwu went to work, saying that he would come back for dinner at noon.

At noon, he rubbed at Li Cheng's house, and in the afternoon, Yang Ruolan and Yang Kaiming were both playing at Li Cheng's house, and Xu Ziling went to the University of Science and Technology alone.

Before he came back, he had already communicated with the school, and this time he would arrange two classes for him, one this afternoon and one tomorrow morning, and the things that Xia Xueyi had lectured on before were ready when he was in Nitan, and when he arrived at the University of Science and Technology, he sat down in Li Lao's office for a while, and he began to lecture.

The venue of this lecture is still the small auditorium of the materials department, and the number of people is about the same as the first time, Xu Ziling is not prepared to talk about too many esoteric things this time, but is ready to talk about the use of new materials in related equipment.

"I won't talk about any theoretical things this time, I will tell you about some new materials used in the 'Thunder Dragon' helicopter......

For the Chinese people, this is the first weapon in China to occupy an important position in the international market, and the students of the University of Science and Technology are more concerned about and concerned about these than ordinary people.

Hearing Xu Ziling actually say this, they waited one by one, and then held their breath and stared, without making any sound, for fear of disturbing the teacher on the podium.
