Galaxy Technology Empire

The four people in Zhang Sihan's dormitory were studying the booklet attentively. They thought they were reading some popular educational book.

In fact, the two major departments added by Dongdao Aeronautical College this time are mainly to train airship pilots and serve the future aerospace business.

Of course, the security company itself also needs a large number of new blood to refresh the original system.

This time, the two new departments added by the School of Aeronautics will recruit students in Dongdao and China. It is expected that the airship department will enroll about 20,000 students, and the aerospace department will also enroll 3,000 students.

The airship department has driving majors, maintenance majors, and ground handling majors. The admissions standards are not too strict, mainly because most of these majors are civil aviation.

However, the Department of Astronautics and Astronautics is much stricter. It not only requires undergraduates, but also some astronaut majors, which have very high physical fitness requirements.

In addition, among the original Dongdao air force, those pilots or ground staff who were eliminated and cut out were also transferred to the airship department to re-learn, and they were prepared to arrange for them to run transport airships.

"Chengye, what are your plans?" Some unruly young people asked Li Chengye.

"Where are you, Wu?" Li Chengye asked.

Ma Wu raised his eyebrows: "I plan to change my major to astronaut major. I want to see the romance of the stars and the sea."

"I plan to transfer to the airship department. After all, the salary of an airship pilot starts at 100,000 Mars coins." Li Chengye came to the aviation academy with the intention of switching to civil aviation in the future. Now it is better and he can directly switch to a major.

Ma Wu was not surprised when he heard Li Chengye's decision. After all, the other person's family was relatively ordinary, and Li Chengye's family hoped that he would become a pilot in the future.

"Sihan, Gao Shan, where are you?"

Gao Shan was the most insignificant young man in their dormitory. He twisted his hair:

"I'd better stay and learn to fly."

"I also plan to stay." Zhang Sihan agreed.

"Oh! In that case, let's go have a dinner tonight! Maybe there will be fewer opportunities to meet in the future." Ma Wu suggested.

"Can."

"That's right." Zhang Sihan and the other three also agreed to have a dinner together.

After all, once you change your major, the chances of meeting each other will become less and less. After Gao Shan and Zhang Sihan graduate, they should first go to Tianhan Security for internship; while Li Chengye should be assigned to the airship transportation company; as for Ma Ma, who yearns for the stars and the sea Wu, should go to the aerospace company.

…

In order to break some of the regional color, Dongdao Aeronautical College was renamed United Universe University, and more than a dozen universities and institutions with aerospace majors in the province were transferred or merged.

The main campus is located in Kaohsiung City, and it also has two branches and five large research institutes in Dongdao.

United Universe University also has three branch campuses (Shanmei, Bazhong, and Wuwei) and five large research institutes in mainland China.

And a winter special recruitment was held across the country. Since the enrollment conditions of the Airship Department were not too high, and the temptation of Galaxy Technology's high salary, United Universe University's enrollment across the country was very popular.

After all, once you graduate, you can arrange to work in an airship transportation company, especially since the number of applicants for ground handling and maintenance majors exceeds the enrollment quota by more than ten times.

Ground crew and maintenance professionals do not need to go to the sky. The physical requirements are relatively low and the risk is not high. Of course, the salary standards of ground crew and maintenance workers are not as high as those of drivers, which may only be around 20,000 to 30,000 yuan.

However, Galaxy Technology's comprehensive benefits are good and its future is bright. Now many people are eager to work in Galaxy Technology's companies.

So the enrollment went quite smoothly this time.

However, people have different opinions on Galaxy Technology's sudden opening of a specialized aerospace higher education institution. However, it is a sure thing that Galaxy Technology will enter the aerospace industry. I just don't know what Galaxy Technology plans to do.

…

After Huang Junjie read the experiment log of the Airship Research Institute for a while, Wang Tu had already arranged his office.

"Boss, your office has been arranged."

"Come over and have a look!"

Arriving at the office, Huang Haojie nodded with satisfaction: "I'll be at work these days. Wang Tu, you will call a few researchers in charge of high-altitude airships in half an hour."

"OK."

Huang Junjie clicked on a holographic computer, and with Zhong's assistance, began to check various airships in the Airship Research Institute.

Various airships developed by the Airship Research Institute are in the database. There are [Advance-class transport airship] and [Resolute-class communication airship] that can be put into mass production, and many are semi-finished designs.

For example, the design plan he is looking at now [remote sensing airship platform].

Judging from the design plan of the Airship Research Institute, they plan to design an airship that can fly at the top of the stratosphere, which is about 60 kilometers above sea level.

Then use this airship platform to achieve the function of a remote sensing satellite.

Theoretically, airships can fly within the atmosphere, and sounding balloons can often fly thirty or forty kilometers, but why can't current airships reach such high altitudes?

Nowadays, mainstream soft airships generally do not discharge helium during the process of ascending and descending, but adjust the total mass by inflating and deflating the internal air bag to achieve the purpose of ascending and descending. When the altitude increases due to the low external pressure, the helium expands. Reducing the available amount of air bag will cause a decrease in adjustment ability.

When it reaches a certain altitude, the volume inside is completely occupied by helium, and it reaches the ultimate altitude.

If you want to go up again, you need to release a part of the helium, but this will cause there is not enough helium to provide buoyancy when you return to a low altitude, and helium is expensive. It is generally not an emergency situation (an uncontrolled and unexpected ascent can cause the air bag to expire. It won't be released casually (e.g. if it explodes).

Therefore, the flight height of a general soft airship ranges from a few hundred meters to one or two thousand meters depending on the size and strength of the designed airbag.

When climbing a mountain, you need to find a place halfway up the mountain to release some of the helium, and then fill it back up halfway down the mountain.

Therefore, there are usually a bunch of vehicles on the ground for long-distance airship transfers to provide helium gas, anchoring, maintenance, etc.

Of course Galaxy Technology doesn't need to bother, because they use hydrogen.

In addition, the Airship Research Institute and the Materials Research Institute cooperated to develop a hydrogen curing catalyst. This hydrogen curing catalyst can turn hydrogen into a solid state (metallic hydrogen) and store it. In addition, the metallic hydrogen mixed with this hydrogen curing catalyst does not have Explosive properties.

When hydrogen needs to be replenished, the hydrogen curing catalyst can be reversely stimulated to turn the metallic hydrogen back into a gaseous state.

After adopting a rigid structure, this remote sensing airship platform can theoretically reach the top of the middle layer of the atmosphere, which is about 85 kilometers above sea level.

However, considering that the airship itself needs to carry weight, it may be difficult to reach the top of the mesosphere at an altitude of 85 kilometers, but it is worth a try at the top of the stratosphere itself at an altitude of about 60 kilometers, or at the bottom of the mesosphere.

Huang Junjie operated the holographic projection and made unrecognizable modifications to the remote sensing airship platform of the Airship Research Institute.

He sacrificed the maneuverability of this airship platform and only retained its lifting ability and very slow translation ability.
