“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 most importantly, it 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 sunlight is very abundant, so the operation of solar photovoltaic panels generates abundant electricity.
The only thing that needs to be transported from the earth is the lunar soil 3D printer and related parts and some consumables. However, compared with the huge 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 requires us to study it carefully and refer to it, 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 detection equipment. In addition to some of Haoyu Aerospace's own scientific research 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 reference for us to study the origin of the moon, the evolution of the moon, 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 had been successful once before, the meaning this time was different.
As the old saying goes, once is luck, twice is strength. One success cannot be called success. There may be a lot of luck in it. Two successes can reduce the luck to a minimum. It can also show that success is directly related to one's own performance. This also verifies that Jianmu No. 9 Center Reliable performance of launch vehicles and lunar cargo spacecraft systems. "
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 has a very high recyclability and reusability rate.
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 its very top, at this location, is its huge fairing. The entire fairing is twenty-eight meters long, and the salute reaches 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 low-Earth orbit.
For now, it is still 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, in fact it contains a lot of technology, so the cost is not cheap, not to mention the cost of such a huge fairing, which may reach 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 the two halves of the fairing to be 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 rocket's carrying capacity.
Secondly, this fairing must withstand the huge wind resistance and overload caused by the rocket when it takes off, as well as the vibration generated by the rocket during its flight. It even has to 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, Banghan's 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 recycling system on the two half fairings. This recycling system also requires cost, so this also makes the price of these two half fairings very expensive. "
