Of course, even if they designed this super large aerospace aircraft, the manufacturing time will definitely be much shorter than the design time. However, the manufacturing of the first few prototypes will take at least 3-5 months according to their capabilities of aerospace technology. People still can''t see the takeoff of this super large aerospace aircraft in a short time.


    ……


    Technology mall, Tiangong technology store.


    As usual, after lunch, Wang Bin strolled around the industrial park for a while, returned to his office and entered the technology mall.


    You should know that in the past three years, due to their Tiangong technology, or the whole mankind has a great demand for aerospace technology. No matter what kind of aerospace technology, if they have no technology in Tiangong technology or human civilization, Wang Bing will try to buy it.


    Because of this, the energy coins spent by Wang Bing in the past three years have been incalculable. Even now, there are not many energy coins left in his hands, only less than 1 universal quantity coin.


    You know, according to the judgment of the science and technology mall, at this time, the human civilization in the world where Wang Bing is located has preliminarily mastered the controllable nuclear fusion technology, including thermonuclear fusion and cold nuclear fusion technology. In addition, the per capita life of human civilization has also broken through the age of 120, and the machinery has reached about 130, of course, this is only the per capita life.


    In fact, the average life expectancy of human beings in many regions has exceeded 150. For example, scientists and astronauts of major space companies participating in the earth defense program, after all, the genetic agents they use are not the genetic agents used by ordinary people, but higher-level genetic agents, and their effects are naturally not comparable to ordinary genetic agents.


    Of course, compared with the lifespan of scientists in other space agencies in the world, the lifespan of R & D personnel in China''s space Department and Tiangong technology, as well as astronauts and even soldiers, is longer. After all, who calls Tiangong Technology China''s company, so the genetic agents used are naturally higher.


    Of course, in addition to these two standards, now the whole human civilization only needs aerospace technology to break through the zero civilization. After all, according to the evaluation criteria of the mall, the first-class civilization must have the ability to navigate freely within the galaxy where the civilization is located and the ability to migrate between planets in the information industry.


    So now the level of human civilization has only reached the peak of level zero civilization. If human civilization can go further in aerospace technology, human civilization can break through level zero civilization and reach level one civilization.


    It is also true that in recent years, not only the world''s major space agencies, including official space agencies, are doing their best to develop engines that can be used in aerospace, but also trying their best to improve their aerospace technology.


    Like other space agencies in the world, they have made every effort to develop their space technology in recent years. Otherwise, they will not successfully design a super large space plane with a length of more than 100 meters in just three years, let alone an engine that can provide sufficient power for this super large space plane.


    What''s more, their Tiangong technology has not only developed super large aerospace aircraft and various types of aerospace engines over the past few years, but also designed the first spacecraft in the true sense of the whole human civilization.


    However, despite the time, three years have passed. Although their Tiangong technology has encountered many difficulties and many technical problems in the design of spacecraft, they have never given up their research, development and design of the universe. Until now, according to the shape of submarines in the sea on earth, Wang Bin has completed more than half of the design of their first spaceship of Tiangong technology.


    The remaining questions are much more difficult. According to the current progress of spacecraft design, within this year. The design work can be completed, and the first spaceship of human civilization can be officially manufactured from next year.


    Of course, even so, it is not easy to build a spaceship, especially a real spaceship. After all, after many meetings and discussions by Tiangong technology, aerospace design department and Wang Bing himself, they have made a great difference in the size of the spaceship they predicted before.


    After all, a few years ago, when Tiangong technology just put forward the spacecraft plan, the total mass of the spacecraft was only 100 tons.


    But now the situation is very different from the original, not to mention anything else, just say that the weight of this super large space plane just designed by Tiangong technology has reached the level of three or four hundred tons, so if you search the size of a real spaceship, a spaceship that can navigate in deep space, its volume can''t be less than the space plane!


    Moreover, the smaller the size of the spacecraft, the higher the threat of navigation in the universe, because the smaller the size of the spacecraft means that the thickness of its shell is small, and its resistance to high-speed impact, such as meteorites, is smaller.


    In the solar system, not to mention the asteroid belt, there are countless meteorites near the earth alone, not to mention the whole solar system. Although meteorites are not dangerous for spacecraft in most cases, they are not without.


    This is just a threat from small meteorites. In addition to meteorites, if the spacecraft lands on another planet, there will be more threats to the spacecraft.


    A large spaceship is different. Because a large spaceship has a thick hull, most small meteorites do not pose a threat to it. Even if they encounter its thick hull, they can be completely ignored. At the same time, a large spaceship means that it can hold more fuel and more personnel, It can accommodate more weapons, and its survival ability in the universe is naturally not comparable to that of small spacecraft.


    It is precisely because of this, after many modifications to the design, the final design drawing or estimated total weight of the spacecraft by Tiangong technology has reached nearly 10000 tons, and its length has reached more than 100 meters.


    Even so, in fact, many people in the whole Tiangong science and technology design department are not satisfied with the total weight and volume of the spacecraft. According to their meaning, the weight should reach at least 100000 tons, and the volume should reach the size of the aircraft carrier. Only such a huge volume can have a certain resistance in the universe
