"In addition, we are developing an oxygen curing agent based on the principle of hydrogen curing agent. Although the density of solid oxygen is similar to that of liquid oxygen, it is about 1,400 kilograms per cubic meter.
But if solid oxygen can be stored at normal temperatures and pressures, I believe that the difficulty for fuel and oxidant storage systems will be greatly reduced."
"Of course, if the fuel and oxidizer can be stored at normal temperature and pressure, it will be a great convenience for the design of launch vehicles or spacecrafts." The spacecraft expert agreed.
Many people know that MiLijia has developed quite a few solid fuel rockets or solid-liquid hybrid rockets. This is because liquid hydrogen and liquid oxygen are difficult to store. During launch, fuel and oxidizer need to be added a week or two in advance.
There is a huge problem inside. The initial launch vehicle technology was derived from the Intercontinental Kicker.
If the space rocket uses liquid fuel, there will be no problem.
But Erkiji uses liquid fuel. Once a real conflict breaks out, who will wait for you to refuel for a week or two?
So later on, most of the Intercontinental kickers switched to solid fuel. The reason why I say most is because Mao Xiong’s ones still use liquid fuel.
This is because the furry bears use peptide liquid fuels that are easy to store, and peptide fuels are generally highly toxic.
"If this is the case, the engine of our projection spacecraft can use a hydrogen-oxygen engine." Li Zhongting said.
Wang Guanghai also nodded: "Having a curing agent is perfect for using 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 be enough." The spacecraft expert gave a rough figure.
…
After a morning of deliberations, experts and scholars from Galaxy Technology and the Space Administration preliminarily determined various plans for the mass projection system and the projection spacecraft system.
For the mass projection system, Galaxy Technology is the main force, and the space agency cooperates; for the projection spacecraft system, the space agency is the main force, and Galaxy Technology is the cooperation.
The planning blueprint for the projection spacecraft system is: first, based on a regular hexagonal cylinder with a side length of 3 meters and a height of 12 meters, two projection spacecraft with a volume of 280 cubic meters will be developed.
One is a projection spacecraft for manned spaceflight, code-named "Qinglong"; the other is a projection spacecraft for transporting supplies, code-named "Xuanwu".
Qinglong-class manned projection spacecraft: a regular hexagonal cylinder with a side length of 3 meters, a height of 12 meters, and a volume of 280 cubic meters.
Carbon nanotubes, nano-titanium alloys, graphene and other materials are used as the skeleton and warehouse materials, supplemented by radiation-proof materials such as aluminized polyimide, gold partitions, and other insulation materials.
The weight of the spacecraft hull and equipment is 21 tons.
There are 18 tons of fuel oxidizer in total.
There are 8 astronaut survival chambers, totaling 40 tons.
In addition, it can carry about 21 tons of supplies.
The entire Qinglong-class spacecraft, including fuel, oxidizer and supplies, weighs about 100 tons.
The Xuanwu-class transport and projection spacecraft is very similar to the Qinglong-class manned projection spacecraft.
Since it does not need to carry people, the effective load of the Xuanwu class will reach about 61 tons.
In fact, according to supercomputer simulation results, a payload of 61 tons can enter low-Earth orbit at an altitude of 500 to 600 kilometers.
If the orbital height is 300 kilometers, the payload can reach about 100 tons.
As for the next level of projection spacecraft, the design needs to be adjusted after the Qinglong class and Xuanwu class are put into use.
After all, Galaxy Technology is designing a spaceship for the first time, and although Dongtang Space Administration has designed the Shenzhou spacecraft and the Tiangong Experimental Space Station before, this is the first time for everyone to do this with a spacecraft of this level.
Regarding the mass projection system, since Galaxy Technology’s materials science and technology are almost there, this part can be said to be the time to work hard to achieve miracles.
Just throw the money down and the results will come out soon.
However, for the projection spacecraft, many technical problems only have solutions, and the feasibility of the technology and solutions has not been actually confirmed.
Two o'clock in the afternoon.
Or Galaxy Technology 2017 Building.
Galaxy technology and space systems have entered another big topic.
Discuss how to allocate tasks and adjust the mechanisms of both parties.
This discussion is necessary and inevitable. Since we are going to enter into large-scale exploration of outer space, how to develop and develop, all aspects of the issue must be discussed clearly.
You can't wait until the spacecraft goes into outer space and then send another message: Waiting online! Urgent!
This situation must be avoided, and everything should be prepared in advance as much as possible to avoid improvising.
Huang Haojie spoke first: "In order to unify management, I think an outer space management agency should be established. What do you think?"
Of course, this was said to Zhao Hongxing and others from the Space Administration. Huang Haojie was the one who spoke within Galaxy Technology, and there was nothing to discuss.
"I agree!" Zhao Hongxing nodded. After all, the establishment of a management agency will be conducive to cooperation and communication between the two parties, and can also make space development more standardized and orderly.
"What's the name of this organization?" Wang Guanghai asked.
Everyone is thinking.
"How about calling it the Eastern Tang Outer Space Committee?" Li Zhongting said a name.
"That's inappropriate!" Academician Ma shook his head and explained:
"If we are doing this for ourselves, there is nothing wrong with using Dongtang as the name. If we want to conduct international cooperation in the future, it is best to downplay the name of the country."
As for why international cooperation is needed.
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 on the way.
"Is it called the International Committee on Outer Space?" Li Zhongting said with a smile.
"This name is not good either. It can easily be confused with the International Space Station." Zhao Hongxing was not optimistic about this name, and then said to Huang Junjie:
"Mr. Huang, do you have any suggestions?"
"How about calling it the Space Development and Development Committee, or Space Development Committee for short?" Huang Haojie suggested.
"The name Space Development and Development Committee is fine!" Zhao Hongxing nodded in agreement.
"Yeah! This name can be used." Academician Ma also agreed.
Everyone has no opinion on this name.
The name [Space Development and Development Committee] was decided as a cooperative organization between the space system and Galaxy Technology.
However, just because the name is decided does not mean that the matter is over. Next, we need to discuss how to set up the organization internally, how to manage it, and the establishment of rules and regulations.
After discussion with Huang Haojie, Zhao Hongxing and others, they 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, it must have committee members or members.
After deliberation, the Space Development Committee set up a committee composed of 3 permanent members and 12 members.
There are three permanent members, respectively served by Dongtang Space Administration, Galaxy Technology, and Dongtang Academy of Sciences.
As for the 12 members, what can be confirmed so far is that Tianhan Group occupies one of the places, and the remaining places are naturally for Jiang Taigong to fish for, and those who are willing to take the bait will take the bait.
Of course, you have to join the membership and pay the money first.
Galaxy Technology has a huge say in the management of the Space Development Committee, so some membership reviews and fees must be approved by Galaxy Technology.
Galaxy Technology is not an institution of higher learning that offers 470,000 yuan for free, nor is it a university with one black and three yellow.
I want to get preferential treatment without paying any money.
Go out and turn left. There is a third brother over there who can go to the moon. Go play with him!
Anyway, the membership fee for the Space Development Committee is 1 billion Chinese dollars per year for members and 100 million Chinese dollars per year for observers. Other fees are calculated separately.
And you can’t pass just because you have money. The aerospace system and Galaxy Technology have set a lot of access conditions. As for whether you pass, Galaxy Technology and the space agency have the final say.
