Li Xiang continued:

"In addition, we are developing an oxygen curing agent based on the principle of hydrogen curing agent, although the density of solid oxygen is about the same as that of liquid oxygen, which is about 1,400 kilograms per cubic meter.

However, if solid oxygen can be stored at room temperature and pressure, it is believed that the difficulty for fuel and oxidizer storage systems will be greatly reduced. ”

"Of course, if the fuel and oxidizer can be stored at room temperature and pressure, it is a great convenience for the design of launch vehicles or spacecraft." The spaceship expert chimed in.

Many people know that Mi Lijia has developed a lot of solid-fuel rockets or solid-liquid hybrid rockets, because liquid hydrogen and liquid oxygen are difficult to store, and when launching, it is necessary to fill fuel and oxidizer one or two weeks in advance.

In it there was a huge problem, at the beginning of the launch vehicle technology, which was derived from the Intercontinental II kick.

If it's a space rocket, there's nothing wrong with using liquid fuel.

But the second kicker uses liquid fuel, and if a real conflict breaks out, who will wait for you to refill the fuel for a week or two?

So later, most of the Intercontinental two kickers switched to solid fuel, and the reason why I say most of them is because the woolly bear family is still liquid fuel.

This is due to the fact that the bears use easily stored peptide liquid fuels, which are generally highly toxic.

"If that's the case, the engines of our projection ships can be hydrogen-oxygen engines." Li Zhongting said.

Wang Guanghai also nodded: "With a curing agent, it is perfect to use a hydrogen-oxygen engine." ”

"If the projection spacecraft only needs to operate near low-Earth orbit, I estimate that 2 tons of hydrogen and 16 tons of oxygen will do." The ship's experts gave an approximate number.

……

After a morning of deliberations, the brick scholars of the Galaxy Science and Technology and the Space Administration preliminarily determined the various schemes of the mass projection system and the projection spacecraft system.

The mass projection system, Galaxy Technology as the main force, with the cooperation of the Space Agency; The spacecraft system is projected with the Space Agency as the main force and Galaxy Technology cooperating.

The planning blueprint of the projection spacecraft system is to develop two projection spacecraft with a volume of 280 cubic meters based on a regular hexagonal cylinder with a side length of 3 meters and a height of 12 meters.

One is a projection spacecraft for manned spaceflight, codenamed [Qinglong]; One is a transport material projection ship, codenamed [Xuanwu].

Qinglong-class manned projection spacecraft: hexagonal cylinder, 3 meters long, 12 meters high, and 280 cubic meters in volume.

Carbon nanotubes, nano-titanium alloys, graphene and other materials are used as skeleton and warehouse materials, supplemented by aluminized polyimide, gold separators and other radiation-proof materials, in addition to thermal insulation materials.

The weight of the ship's hull and equipment is 21 tons.

A total of 18 tons of fuel oxidizer.

There are 8 astronaut living compartments, a total of 40 tons.

In addition, it can carry about 21 tons of supplies.

The entire Qinglong-class spacecraft, including fuel oxidizer and replenishment, is about 100 tons.

The Xuanwu-class transport projection spacecraft is similar to the Qinglong-class manned projection spacecraft.

Since there is no need to carry people, the effective load of the Xuanwu class will reach about 61 tons.

In fact, according to the results of supercomputer simulation, the payload of 61 tons can enter the altitude of 500~600 kilometers in low earth orbit.

If it is at an orbital altitude of 300 km, the payload can reach about 100 tons.

As for the projection spacecraft of the next stage, it is necessary to wait for the Qinglong class and Xuanwu class to be put into use before adjusting the design.

After all, Galaxy Technology is the first time to design a spaceship, and although the Dongtang Space Agency has previously designed the Shenzhou spacecraft and the Tiangong experimental space station, it is the first time for everyone to play this with a spaceship of this level.

In terms of mass projection system, since the material science and technology of Galaxy Technology are almost the same, this part can be said to be the time for a miracle.

Only throw the money down, and the results will come out soon.

However, in the part of projecting spacecraft, many technical difficulties are only plans, and there is no actual confirmation that the technology and solutions are feasible.

Two o'clock in the afternoon.

Or Galaxy Technology 2017 Building.

Galaxy technology and space systems have entered another big topic.

Discuss how to assign tasks and adjust the run-in mechanism of the two sides.

This discussion is necessary and inevitable, and since we want to enter the large-scale exploration of outer space, how to open up and develop must be clearly discussed in all aspects.

You can't wait for the spacecraft to go to outer space, and then send another one: wait online! Urgent!

This situation must be avoided, and all should be prepared as far in advance as possible to avoid impromptu cramming.

Huang Haojie spoke first: "For the sake of unified management, I think there should be a management body for outer space, what do you think?"

Of course, this was said to Zhao Hongxing and others of the Space Agency, and Galaxy Technology is Huang Haojie's word hall, and there is nothing to discuss.

"I agree!" Zhao Hongxing nodded, after all, the establishment of a management organization is conducive to cooperation and communication between the two sides, and it can also make space development more standardized and orderly.

"And what's the name of this agency?" Wang Guanghai asked.

Everybody is thinking.

"How about calling the Eastern Tang Committee on Outer Space?" Li Zhongting said a name.

"No!" Academician Ma shook his head and explained:

"If this is our own play, it is understandable to use Dongtang as the name, and if we want to carry out international cooperation in the future, it is better to dilute the name of the country."

As for why international cooperation is taking place.

It's very simple, implement the standards of the Eastern Tang Dynasty, let other countries bear the funds, suppress the development of other countries' aerospace forces, and make some small money by the way.

"Is it called the International Committee on the Peaceful Uses of Outer Space?" Li Zhongting said with a smile.

"The name is also not good, it is easy to confuse with the International Space Station." Zhao Hongxing was not optimistic about this name, and then said to Huang Haojie:

"Does Mr. Huang have any proposals?"

"How about calling it the Space Exploration and Development Committee, or Space Development Committee for short?" Huang Haojie mentioned one.

"Space Exploration and Development Committee? The name can! Zhao Hongxing nodded in agreement.

"Hmmm! The name can be used. Academician Ma also agreed.

There was no opinion on the name.

The name [Space Exploration and Development Committee] was decided as a cooperative organization between Space Systems and Galaxy Technology.

However, the name is decided, it does not mean that the matter is over, and it is necessary to discuss how to set up the internal structure of the organization, how to manage it, and the establishment of rules and regulations.

After discussing with Zhao Hongxing and others, Huang Haojie decided to set up a logistics support department, a technology research and development department, a projector management department, a spacecraft management department, an outer space management department, an astronaut management department, and a planning and research department within the framework of the Space Development Committee.

Since it is a committee, there must be members or members.

After deliberations, the Space Development Committee established a committee consisting of 3 permanent members and 12 members.

The three permanent members are respectively served by the Dongtang Space Bureau, Galaxy Science and Technology, and the Dongtang Academy of Sciences.

As for the 12 members, what can be confirmed at present is that Tianhan Group occupies one of the places, and the remaining places are naturally Jiang Taigong fishing, and those who wish to take the bait.

Of course, if you want to join the club, you have to pay the money first.

In the management of the Space Development Committee, Galaxy Technology has a very huge right to speak, so some review and membership fees must be approved by Galaxy Technology.

Galaxy Technology is not a chimpanzee or crooked nuts to send 470,000 yuan to an institution of higher learning, let alone a university with one black and three yellows.

Want to pay without paying? Still want preferential treatment?

Go out and turn left, there is a third brother who can go to the moon over there, go play with the third brother!

Anyway, the entrance fee of the Space Development Committee is 1 billion Chinese dollars per year for members, 100 million Chinese yuan per year for observers, and other expenses are calculated separately.

And it's not that you can pass if you have money, the space system and Galaxy Technology have set a lot of access conditions, as for whether to pass or not, it is all Galaxy Technology and the Space Agency that have the final say.
