In fact, whether it is the classic Tiangong Palace or the " Tianwen " by Qu Yuan , they all reflect the fantasy of our people about the sky. In fact, from a long time ago, the people of our country have begun to project many romantic plots onto the untouchable sky, which seems to represent an intermediate exploration goal of our human beings.
But now our country has achieved this goal. Since Qian Xuesen proposed the concept of aerospace, our country has realized its dream of lunar exploration and has also fought for decades.
also completed phased results a few days ago. The Dream Sky Experimental Cabin , which was just launched at the end of October, successfully completed its transposition in space. In fact, when we first started designing the Tiangong Space Station, the T-shaped structure was announced, which has been completed, and China's aerospace industry has also taken a big step forward.
In fact, the three huge cabins of space station are T-shaped structures, including Wentian, Mengtian, and Tianhe core cabins. After operation, a new structure has been formed.
Its appearance also officially shows that my country's space station has ended its construction stage and has begun to go to its development stage. T-shaped space stations will become the most basic shape in my country. In the future, whether it is a manned spacecraft or a cargo transport, or a spacecraft connected to the space patrol space telescope will have a T-shaped structure.
So many people may ask, how did the T-shaped structure come about? In fact, the design of this structure has been repeatedly studied by scientists, and the issues that need to be considered include difficulty, cost and accuracy. my country's space station belongs to a mixed configuration of building blocks and trusses. Now that this method has been studied, I believe that my country's aviation industry will definitely go further. After the inversion of
, the docking capabilities of the core pod in the radial, forward and backward direction will not be affected, and it will also lay a good foundation for future development. In fact, in the future, there will not only be T-shaped space stations, but also space stations with earth-shaped structures and cross-shaped structures. After the
space station was built, the total weight reached 90 tons, and it has three very large cabins, and all have sun wings . There are two groups of Tian and core cabins, and Wentian and Mengtian also have two groups, a total of six groups, which are all flexible sun wings independently created by our country.
Everyone knows that International Space Station is a very huge monster, with a total of more than 400 tons, with eight large sun wings, and even six cabins. Whether in terms of number or size, they are much larger than my country's space stations.
Although my country's space station can reach 180 tons in the future, it is still not as good as international ones. However, according to the statistics of data, we can see that even if my country's space station and the international space station are much different in number and weight of solar wings, the power generation rate is similar. This means that although my country's space station is small, the power generation rate is not small. This may be short and concise.
Many people will be curious about why eight panels of the International Space Station can generate 80 to 120 kilowatts of electricity, but they cannot compare to my country's six pieces. The power generation power of my country's space station has long exceeded 100 kilowatts.
Why is this? Is it because our solar panels are big? In fact, it is not. In comparison, the solar panels of international power stations are larger. So what is the reason?
actually because of different materials and different technologies. If we only look at the surface, we will find that the solar panels used in our space stations are no different from those in the international market, but in fact the internal materials are different, and they are also the products of the two eras.
The sun wing used in my country's space station is developed and produced by itself. It is very reliable, has a long service life, and can be re-expanded and retracted. It is very thin. It uses brand new materials, which greatly increases the power generation power. It also has a special sunrise setting, which will follow the sun to ensure power generation power, and also uses lithium batteries to store energy.
In fact, many years ago, French physicists discovered the photovoltaic effect , which also brought great benefits to mankind and opened a new door to energy. However, because of the backward development of science and technology at that time, this technology was not well utilized. It was not until the 1950s that people began to work hard to develop the space industry, and this technology was reused. In 1958, it was used on the satellite in the United States for the first time. Although the power generation rate is very low, it is also a great progress.
my country has put a lot of effort into the development of science and technology, so it has made great progress. Now the entire space station has a daily power generation of 1,000 degrees, which has played a very important role in the development of science and technology in my country. In fact, when the solar wing was invented, Chinese researchers encountered many difficulties. They not only had to deal with strong radiation, but also had to deal with a height temperature difference of 300 degrees, and the environment was very harsh.
Fortunately, our country's researchers did not give up. With the research of generations of scientific researchers, my country successfully invented Tiangong No. 2 in 16 years, and also used a new technology of rigid triple-junction gallium arsenide panels. Because of this, my country's solar wing technology is at the forefront of the world. I hope our country will not be proud and can continue to work hard to produce more and better materials to contribute to our country's giant ships.
