The four people in Zhang Sihan's dormitory were studying the pamphlet intently, and they didn't know what kind of educational books they thought they were reading.

In fact, the two professional departments added by the East Island Aviation 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 rush the original system.

This time, the two additional departments of the School of Aviation will be re-enrolled in the East Island and in China, and it is expected that the airship department will enroll about 20,000 people, and the aerospace department will also enroll 3,000 people.

The airship department has piloting, maintenance, and ground handling majors, and the enrollment standards are not too strict, mainly because most of this major are civil aviation.

However, the Department of Astronautics is very strict, not only for undergraduates, but also for some astronauts, who have very high requirements for physical fitness.

In addition, among the original East Island air forces, those pilots or ground crews who were eliminated and cut out were also transferred to the airship department to re-study, ready to arrange for them to run transport airships.

"What are your plans to succeed?" Some uninhibited young people asked Li Chengye.

"Ah Wu, what about you?" Li Chengye asked rhetorically.

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

"I plan to transfer to the airship department, after all, the salary of the airship pilot starts at 100,000 Mars coins." Li Chengye came to the Aviation College before, planning to change to civil aviation in the future, but now it is better that he can directly change his major.

As soon as Ma Wu heard Li Chengye's decision, he was not surprised, after all, the other party's family was relatively ordinary, and Li Chengye's family hoped that he would become a pilot in the future.

"Sihan, what about you?"

Gao Shan was the most non-existent young man in their dormitory, and he curled his hair:

"I'd better stay and learn how to fly an airplane."

"I'm going to stay, too." Zhang Sihan echoed.

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

"Yes."

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

After all, once this major is changed, there will really be fewer and fewer opportunities to meet in the future, and after Gao Shan and Zhang Sihan graduate, they should first go to Tianhan Security for an internship; Li Chengye should be assigned to the airship transportation company; As for Ma Wu, who yearns for the sea of stars, he should go to the aerospace company.

……

In order to break some regional colors, the East Island Aviation Institute was renamed United Space University, and more than a dozen institutions of higher learning and institutions with aerospace majors in the province were transferred or merged.

The main campus is located in Kaohsiung City, and there are also two branch campuses and five large research institutes in Dongdao.

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

And a winter special recruitment was carried out all over the country, because the enrollment conditions of the airship department are not too high, coupled with the high salary temptation of Galaxy Technology, the enrollment of United Universe University in all parts of the country is very hot.

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

Ground service and maintenance professional, is not to go to the sky, for the physical fitness requirements are relatively low, the danger is not high, of course, the ground and maintenance staff salary standard is not as high as the driver, may only be about twenty or thirty thousand.

However, the comprehensive benefits of Galaxy Technology are good, and the future is bright, and now many people want to work in Galaxy Technology's enterprises.

So this time the enrollment was quite smooth.

However, the people have different opinions about the sudden opening of a special aerospace institution of higher learning by Galaxy Technology, but it is a sure thing that Galaxy Technology is going to enter the aerospace industry, but I don't know how Galaxy Technology intends to do it.

……

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

"Boss, your office is arranged."

"Let's go check it out!"

When he came to the office, Huang Haojie nodded with satisfaction: "I've been working in the office for the past few days, Wang Tu, after half an hour, call a few researchers in charge of high-altitude airships to come over." ”

"Okay."

Huang Haojie clicked on a holographic computer, and with the assistance of Zhong, he began to check the various airships of the Airship Research Institute.

The various airships developed by the Airship Research Institute are in the database, including the [Advance Transport Airship] and the [Steadfast-Class Communication Airship] that can be put into mass production, and many of them are semi-finished designs.

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

Judging by the design scheme of the Airship Institute, they plan to design an airship that can be at the top of the stratosphere, that is, at an altitude of about 60 kilometers.

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

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

Now the mainstream soft airship generally does not discharge helium in the process of rising and falling, and adjusts the total mass by inflating and deflating the internal air bag to achieve the purpose of rising and falling, when the height increases due to the low external pressure, the helium expansion reduces the available quota of the air bag, which will cause a decrease in the adjustment ability.

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

If you want to go up, you need to release some helium, but this will cause not enough helium to provide buoyancy when you return to a low altitude, and helium is expensive, and it is generally not an emergency (uncontrolled accidental ascent causes the airbag to burst or something) and will not be released casually.

Therefore, the altitude of the general soft airship flight is in the range of a few hundred meters to one or two kilometers according to the size and strength of the designed airbags.

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

Therefore, there is generally a bunch of vehicles on the surface of the airship long-distance turning site to provide helium, anchoring, maintenance and so on.

Of course, Galaxy Technology doesn't need to go through much trouble, because they use hydrogen.

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

When hydrogen needs to be supplemented, the hydrogen curing catalyst can be stimulated to reversely turn the metallic hydrogen 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, that is, at an altitude of about 85 kilometers.

However, considering that the airship itself needs to carry weight, it may be difficult to do it at the top of the middle layer at an altitude of 85 kilometers, but the top of the stratosphere at an altitude of about 60 kilometers by itself, or the bottom of the middle layer, is worth trying.

Huang Haojie operated the holographic projection to make unrecognizable modifications to the remote sensing airship platform of the Airship Research Institute.

He sacrificed the airship platform's maneuverability, retaining only its ability to lift and fall, and its very slow ability to pan.
