Military Technology

"Secondly, please pay attention to the part of our secondary rocket. There is an additional device, which is our foldable flying wing. This time, we will conduct a fixed-point landing experiment of the secondary rocket. This pair of foldable flying wings will be safe. One of the secrets to returning to the atmosphere.

Finally, in terms of thrust, this Jianmu-2 modified rocket has increased the low-earth orbit carrying capacity of the rocket from 4.2 tons to more than 6 tons, which can be said to have increased by nearly half. This also means that it can transport heavier spacecraft into space. "

In addition to the launch process, there are also many points in this recovery work. For example, we will carry out the off-site recovery of the first-stage rocket. Then there is the air recovery of the two halves of the fairing, and finally the re-entry and fixed-point landing experiments of the second-stage rocket. "Yu Chengwu introduced with a smile.

"Regarding the re-entry and fixed-point landing experiments of the second-stage rocket, some experts analyzed that this is the recovery experiment of the second-stage rocket that you are conducting, and I don't know if this news is correct.

In addition, what does it mean if the experiment is successful, and what is the help to our aerospace field. "Susie continued to ask.

Um, this question... Yu Chengwu hesitated for a while, but finally nodded and said: "We are just conducting an experiment and exploration on the recycling technology of the second-stage rocket, and it is not certain whether it will be successful or not.

This is not to say that the experiment was successful, so the second stage rocket can be recovered and reused like the first stage rocket.

This is not the case. In fact, there are many conditions and requirements that determine whether the secondary rocket can be recovered. It does not mean that it can be done with this technology.

First of all, we are a commercial aerospace company, and all our projects are centered around the four words commercial aerospace.

Others will not give us a penny. Except for the huge allocation and support from our head office, our research funds need to be solved by ourselves.

To put it bluntly, we have to support ourselves.

So always, cost and profitability are the primary issues before us. We can't be as cost-free as other institutions, we can't do that.

Therefore, before carrying out a project, the first thing we should consider is the cost and whether the project is profitable.

Take this secondary rocket recovery technology project as an example. If it costs too much, then we have to think carefully. If its input and output are not proportional, and the cost of recycling is much higher than the cost of remanufacturing, then it is not worth it, and we have to abandon this project.

But at present, we are just exploring in the early stage. As for what will happen, it is still unknown.

However, we are still very optimistic about the development prospects of this technology itself. If this project is successful, it will mean that we can greatly reduce the cost of a single launch, thereby reducing the launch price to the lowest level, laying a solid foundation for us humans to use space peacefully and enter the universe on a large scale. Base.

At that time, space travel will no longer be a monopoly of the rich. At that time, you only need to pay a fee that is not much more expensive than an air ticket, and you can board the spaceship and go to the universe to experience a day or a few days of weightlessness.

Even, if the technology is mature in the future, our ordinary people can go to the moon or even Mars to start an interstellar journey between stars. "

The dream you mentioned is too far away, can we see it? In addition, is the "Oasis One" inflatable inflatable experimental capsule you launched this time also preparing for space tourism and interstellar exploration? Susie took the opportunity to ask.

Hearing Susie's question, Yu Chengwu showed a hearty laugh, then looked at Susie and replied straightforwardly: "Yes,

Our generation will see, that day is not far away.

You are right, our "Oasis One" inflatable experimental space capsule is indeed preparing for our long-term stay in space and alien planets, such as the moon, Mars, Enceladus and other planets. .

Whether it is space, or the moon, Mars, or even Enceladus, their environments are very harsh.

In order for us humans to survive, we must first have a shelter, and there must be sufficient water, air, and food.

Water source At present, we have detected that there are considerable reserves of glaciers in the south pole of the moon and the south pole of Mars, and NASA scientists have also discovered liquid water flowing with the seasons on the surface of Mars.

This also laid a very important foundation for our human production, because we all know that water is the source of life.

With water, we can separate the oxygen we breathe from the water.

So now there are only two problems before us, housing and food.

In space, the only way we get resources is by resupply from Earth. This method is not only inefficient, but also very difficult and costly.

So at present, we can only maintain a few astronauts to survive on the space station. If there are more people, more materials will be consumed, and the cost will be huge.

Compared with materials, the construction of a space station is a huge project. It is possible to build a space capsule of several tons or more than ten tons into space, and then build a narrow living space of a few square meters or ten square meters. This may be the most expensive on earth. house up.

And we research and test this inflatable inflatable experimental space capsule, hoping to use lower cost to build a larger activity space for our astronauts, so that it can accommodate more people and more experimental equipment. .

Even like I said, if there is enough space, why don't we grow vegetables in space, which is our exclusive talent. "

Hehehehe... Susie laughed when she heard his answer, then immediately held back her smile and motioned him to continue.

Yu Chengwu nodded and continued: "The same is true for lunar exploration and Mars exploration. If we want humans to produce on it, we must have a living space. The landing pod we launched is obviously too small.

And if you want to build a scientific research station, you are on the moon and Mars far away from the earth, or even farther away on Enceladus. Therefore, this is a time-consuming and labor-intensive project, which is difficult to complete in a short period of time.

At this time, this inflatable inflatable experimental space capsule can perfectly solve this problem. Even, we can also use this inflatable inflatable space capsule to build a huge living experiment base for more people to live in.

Moreover, we can also set aside a special land in it to grow vegetables to our heart's content, so that the story of growing potatoes on Mars is no longer just a bridge in the movie, but a real life. "
