After Zhang Jiang finished speaking, he glanced at everyone, and then continued: "I have said so much, everyone should also have a general understanding of the giant hard airship. The biggest advantage of the airship over the airplane is its unbeatable time in the air. The flight time of an airplane in the air is calculated in hours, while the airship is measured in days.

Although the airship has such and such advantages, it also has many disadvantages. First of all, he is very affected by weather factors, wind, rain, snow and fog will affect the voyage, and the biggest impact is the wind. Giant airships are large and sensitive to crosswinds, making them difficult to maneuver.

It is difficult to operate the ground operation of the airship anchoring and mooring. The airship is loaded with a large amount of cargo, and after one-way transportation and unloading, the same amount of ballast is required. Airships are mostly powered by heavier-than-air aircraft, and their efficiency is limited by the low speed of the airship and cannot achieve high efficiency values.

But all of the above problems can be solved with guò technology. Now there are several main problems, first of all, the design of the hull, buoyancy body, wing, fuselage, tail, propulsion system and other integrated design technology. This is a hassle, but after all, we are standing on the shoulders of giants, and our database is quite comprehensive about airships, so this problem is best solved.

The second is the choice of power, we certainly don't have the ability to design a new engine to use as the power system of the airship. But we got a lot of KAMAZ spare engines in the Russian army warehouses, including KAMAZ V-8 diesel engines: 10.85 litres Euro I for 4x4 (240 hp) and 6x6 (260 hp) chassis, 11.76 litres Euro II with 360 hp. These engines have been properly modified. can be the power system of the airship.

Now I want to talk about the biggest difficulty we have encountered in developing a giant airship. That is the choice of fuel gas for the airship, and if you choose hydrogen, not only will you not be satisfied, but even I will not be able to agree. Everyone knows that hydrogen is flammable, and such a safety hazard must not be allowed to appear.

But here's the problem, helium is a rare gas with great industrial value and is a very important strategic material. Most of the world's helium is extracted from large natural gas wells, and the helium content of natural gas in Eastern Siberia in Russia is as high as 0.22%-0.26%.

Although extracting helium technically we have no problem. But with our current capacity, we simply cannot form such a large scale of production. The helium needed for a giant airship. It is calculated in tens of thousands of cubic meters, and this is the biggest problem in the development of our giant airship. ”

Zhang Jiang's words immediately poured a basin of cold water on everyone, if there was not enough helium, the giant airship would not be able to talk about it at all. Everyone was silent. I didn't have an idea for a while.

Li Ming thought for a moment and said, "If you use hydrogen." If we rely on our own production. Can it meet the needs of giant airships? ”

Zhang Jiang nodded and said: "The hydrogen industry method is relatively simple, and there are many methods, so of course there is no problem if hydrogen is used." It's just that hydrogen has a lot of disadvantages. Safe storage and transportation is not easy, it is light and elusive, spreads quickly, and needs to liquefy at low temperatures, which can cause valves to clog and create unnecessary pressure. ”

Li Ming thought for a while and said: "Then let's change our thinking, start with solving the safety of hydrogen, and start with the research on hydrogen storage in technology, whether there is any hope to eliminate this hidden danger." ”

Zhang Jiang shook his head and said: "We are not sure, this is a major matter of human life, and no one dares to play this package ticket." ”

Gao Jianguo said: "In this way, Lao Zhang, you go back and start the design first, solve all the other problems, and then concentrate on the problem of gaseous fuel." Can we design a small airship as the Air Department said, let the Air Department train first, and accumulate some experience from it. ”

After the people in the arsenal left, Li Yuancong and Ding Weiguo became listless, and it seemed that they had lost confidence in their proposed big airship plan.

Gao Jianguo comforted: "It's okay, don't be discouraged, if not, we will develop a hydrogen airship, and the Zeppelin has been flying for so long, isn't it a." Besides, the technology we have now can be worse than theirs. Go back first and continue to refine your plan. ”

When Zhang Jiang returned to the arsenal, he immediately summoned the personnel of the technical department, arranged a lot of work, and formed a public relations team to overcome the technical difficulties of the giant hard airship.

In fact, there are no technical barriers, there are many things in the database of the technology department, and now their difficulty is not technology, but to transform the technology they master into productivity. There is also the fact that the materials needed for the giant airship are massive, including the frame, the outer mask, and the airbag, anyway, the resources they bring from modern society are definitely not enough.

Zhang Jiang knew that it would be impossible for the arsenal to complete this plan alone, so he took the plan of the Air Force Department and went directly to the Science and Technology Commission.

A group of old guys from the Science and Technology Commission were also very touched when they saw the plan, and if the momentum of science and technology workers came up, no one would be able to stop it. Without saying a word, they brought in the leaders of various departments of the company and the heads of the technical departments.

The company's technical staff held a meeting for several days, although they all realized the value of the airship, but the opinions were not unanimous, many people thought that this project could be carried out, but not now, when the company's basic industry has a certain foundation, and then start the project.

There are also people who think that airships are only transitional scientific and technological products, and in the end they have to return to the direction of the aircraft aviation industry, and now the airship not only consumes a lot of resources, but also affects the company's investment in the aircraft industry in the future, and it is still necessary to take the aircraft aviation industry as the direction of development.

Liu He, deputy director of the Science and Technology Commission, was the most supportive of this plan, and he also expressed his views.

"The Air Department's plan is very forward-looking, and people may think that this plan is only of military value, but everyone is wrong. I think this program is of inestimable strategic importance to our Far East company. It's even equivalent to the big plane program we have in modern society.

Think about how long it will take us to get to Manila by boat now. If we have an airship that increases its speed by at least 5 times, the range will not be even greater, and we will even be able to fly to any corner of the world in a giant airship in the future. Of course, the development of a giant airship is a difficult test for our company, and it will even consume a lot of resources, but I think it is still necessary to do it, even if it is done for 10,000 years.

We have established a design and development team for large airships and formed a research and development base. We can start from scratch and slowly accumulate experience, before the development of our aircraft industry, giant airships will have an irreplaceable role, and I believe that this will be a long time. This is the first time for our company to undertake such a huge industrial project, if the development is successful, it will also play a positive role in promoting our company's basic industry. ”

The technical staff of the science and technology committee and the company got together and argued for a few days, and the two sides reached a stalemate, so the lawsuit was brought to several managing directors of the board of directors. The intellectuals demanded that a general meeting of the board of directors be convened to vote on the airship plan.

Several managing directors of the board of directors of the company attached great importance to this matter, and immediately convened all the members of the board committee to study and prepare for the company's first general meeting of directors and vote on the big airship plan.

Gao Jianguo and Li Ming also shook their heads and smiled bitterly, they didn't expect a plan of the Air Force Department to cause such a big thing. For the first time since the company came to this time, all the directors of the board of directors voted on a plan.

The general office of the company set up a preparatory committee for the general meeting of the board of directors, compiled and printed more than 2,000 copies of the big airship plan of the Air Force Department, distributed them to all employees of the company, and arranged a meeting place in a vacant steel structure workshop.

The old guys with various opinions in the science and technology committee went deep into the company's various technical departments to find some experts and technicians who held the same concept as them, and now three voices have gradually formed.

One is absolutely supportive of this big airship plan, the other is resolutely opposed, and the other is in favor of this plan, but advocates postponing it for a few years and waiting for the company's basic industry to reach a certain scale before starting research and development.

After the statistics of the preparatory committee, they also made a voting plan for the general meeting of all directors, that is, to take out the three opinions of the company separately for all directors to vote.

Prior to the vote, each of the three views will send a representative who will each have 30 minutes to present their arguments and seek more support from the directors.

Ten days later, all the employees of the company gathered at the site of the board meeting, and even the employees who were far away in Jeju Island and Dongfang Town were left with only a few people on duty, and the rest of them all rushed back.

The whole steel structure workshop is full of long chairs, this time the protagonist is all the directors, several members of the board of directors are also sitting below, there are several tables in front of the venue, there are several preparatory committee staff standing in front of the table, and there is also a ballot box.

Three different groups sat in the front row of the venue, divided into three distinct areas. These days, they spend their spare time researching strategies to convince more directors to support them when they speak their arguments.

In the current form, the Steady Progressives have the upper hand, and they all agree to engage in airships, but they do not advocate doing it now, which also represents the ideas of the vast majority of the company's employees, so the Steady Progressives occupy the vast majority.

The radical faction that supported this plan also expressed support for the overwhelming majority of the cadres and fighters of the Military Commission.

The rhapsodic faction that opposed this plan had the least number of personnel, but among them there were a few leading weaponists such as Li Tiexiong, who were propagating their ideas everywhere these days, and they had also pulled some people, but they were alone compared to the other two factions.
