"In this way, the quartz glass in the lunar soil will melt and become its natural adhesive to bond with other substances. The printed and stacked building walls will be strong and have no gaps.
And another advantage of this kind of printed building is that it is formed in one piece, so the structure is relatively stable, and architectural themes of various sizes and shapes can be printed according to your own needs.
Secondly, because this kind of building uses dissolved quartz stone and glass fragments as an adhesive to form the building body, it is very easy to repair in the later period. You only need to re-dissolve the material to repair the damaged parts.
Finally, and the most important thing is that its cost is very cheap. The materials it uses are all existing lunar soil on the moon, and it only needs to be collected and screened.
In addition, the energy it consumes is electricity, and these solar photovoltaic power stations that have been installed on the moon can provide the required electricity.
Because there is no atmosphere on the moon, the sun's rays are very abundant, so the solar photovoltaic panels operate to generate abundant electricity.
The only thing that needs to be transported from the earth is the lunar 3D printer, related parts, and some consumables. However, compared with the lunar scientific research station with a huge construction area, these are not worth mentioning at all.
If these materials have to be transported from the earth and such a large scientific research station is built, the cost will undoubtedly be very high. This is something that private commercial aerospace companies like Haoyu Aerospace cannot afford, and it is also difficult for most countries.
bearable.
It should be said that this method has to be carefully studied and referenced by us, so the experts and professors we went to inspect gave very high evaluations."
Professor Huang on the side continued what Director Zhang said: "In addition, this mission will also carry a lot of scientific research and detection equipment. In addition to some of Haoyu Aerospace's own scientific research and detection equipment and related materials, it also carries
Experimental detection instruments from many scientific research institutes and universities at home and abroad.
These experimental detection instruments will provide very important data references for us to study the origin of the moon, its evolution, and the environment on the moon."
Professor Zhang next to him nodded and said: "Actually, there is another highlight of this mission, and that is the launch mission itself.
It should be said that this mission will be a very huge test for the Jianmu-9 heavy-lift launch vehicle system and the lunar cargo spacecraft system.
Although it has been successful once before, the meaning this time is different.
We have an old saying, once is luck, twice is strength. One success cannot be called success, there may be a lot of luck in it, but two successes can minimize the luck component, and it can also show that success is
It is directly related to its own performance, which also verifies the reliable performance of the Jianmu-9 center launch vehicle and the lunar cargo spacecraft system."
Director Zhang took a model of the Jianmu-9 heavy-lift launch vehicle on the table in front of him and continued: "Let's talk about the Jianmu-9 heavy-lift rocket first. This rocket is very powerful. This is the model of Haoyu Aerospace.
A high-thrust launch vehicle independently developed by Tianjin that is recyclable and reusable.
Its take-off weight is nearly 2,000 tons, its low-Earth orbit transportation capacity reaches nearly 60 tons, and its synchronous orbit transportation capacity can also reach nearly 30 tons. It can launch a lunar cargo spacecraft of more than 20 tons into the Earth-Moon Transfer Orbit.
superior.
The entire rocket is seventy-five meters high, very tall and majestic. At the top of it, at this position, is its huge fairing. The entire fairing is twenty-eight meters long, with a length of 12.5 meters.
Therefore, a very large internal load space can be formed. This space can accommodate two buses running in our city, and the extra gap can also accommodate four more cars.
Not only that, its huge carrying capacity can also transport these vehicles to the synchronous orbit. In other words, its huge carrying capacity can transport a nearly 60-ton most advanced main battle tank in the world to
Above low Earth orbit.
For now, it is still considered one of the heavy-lift launch vehicles with the largest carrying capacity in the world, and there are only a handful of vehicles that surpass it.
And both halves of the fairing can be recycled and reused. The two halves of the fairing on this rocket this time are the fairings on the Jianmu-9 last time. They were recycled and refurbished and used on this rocket.
.”
After hearing what Director Zhang said, the host on the side couldn't help but asked: "Director Zhang, we know that the fairing is a shell that protects the spacecraft inside. Is it meaningful to recycle it for reuse, or is it just used by Haoyu Aerospace to show off its skills?
the wrist of."
No, Director Zhang shook his head: "This is not to show off their recycling technology, but it has a very practical significance. To put it simply, it is to save costs and save money.
Although it is just two shells put together, it actually contains a lot of technology, so the cost is not cheap, not to mention such a huge fairing, which may cost millions or tens of millions.
.”
It's so expensive. Isn't this a thin shell? The host was obviously a little surprised. He didn't expect that the two halves of the fairing were so expensive.
Hehehe...
After hearing the host's words, Director Zhang and Professor Huang both laughed.
Professor Huang explained with a smile: "You are right, it is a shell that protects the load inside, but the two halves of the fairing contain a lot of technology, such as how such a large fairing needs to be manufactured so that it cannot deform, and it must have
It must have a certain strength and toughness, and the weight should not be too heavy. If it is too heavy, it will crowd out and waste the carrying capacity of the rocket.
Secondly, this fairing must withstand the huge wind resistance and overload caused by the rocket taking off, as well as the vibration generated during the rocket's flight. It must even resist rain erosion, and has certain heat insulation, warmth retention, and anti-corrosion capabilities.
Finally, the two halves of the fairing can not only be brought together, but can also be separated when separated. There are too many cases of launch failure because the fairing cannot be opened, both at home and abroad. For example, Bang Korea
That rocket failed because the fairing could not be opened, preventing the satellite inside from being released.
For such a huge fairing to be successfully opened during high-speed flight, and to be opened 100%, this requires very high technical reliability.
Moreover, there is a recovery system on the two half fairings, and this recovery system also requires cost, so this also makes the price of these two half fairings very expensive."
