As the boss of X aerospace company, mark is naturally very clear about the difference between Tiangong technology''s self-use engine and the export engine.


    According to his understanding, Tiangong''s self-use engine is at least one-third more powerful than the export engine, which is only in the aspect of pulse detonation engine.


    As for other versions of Tiangong technology, Tiangong technology does not sell them at all, except Huaxia.


    You know, according to the information he obtained from secret channels, Tiangong technology has not only pulse detonation rocket engines with high thrust, but also developed a variety of engines that can be used for aircraft.


    These include ion medium engines at the level of 100 kn, isotope engines at the level of 100 kn, and nuclear fusion rocket engines with a thrust of more than 100 tons.


    For these engines, whether they are x aerospace companies or other space agencies, they are very jealous.


    These companies don''t have any good methods for Tiangong technology. After all, Tiangong technology doesn''t sell these engines.


    In addition, these companies, including mark, know that because the technology of these engines is complex and the material requirements are extremely high, even if Tiangong technology puts the drawings of these engines in front of them, they can''t manufacture these engines.


    It is precisely because these companies clearly know the gap between themselves and Tiangong technology, so in recent years, these companies have gradually eliminated the idea of using improper means to obtain Tiangong Technology drawing data.


    Because at this time, they and Tiangong technology are no longer on the same order of magnitude in technology.


    It can even be said that the technical level of Tiangong technology may have reached the first level of Carl civilization level, but their technical level still stays at the level of 0.9 civilization level, but there is a gap of 0.1 civilization level.


    Don''t underestimate the 0.1 civilization level gap. You should know that the 0.1 civilization level gap is actually the difference between heaven and earth.


    You know, level 0.9 civilization only belongs to level 0 civilization, but level 1 civilization is already a real cosmic civilization, that is, level 0 civilization is actually just a star civilization, but level 1 civilization is already a veritable cosmic civilization, which can sail freely in the planetary system.


    So once there is a war between level 0 civilization and a level 1 civilization, which level 0 civilization will lose.


    After all, class zero civilization cannot attack spacecraft in the universe.


    Of course, everything is not absolute. If a zero civilization has reached the level of 0.99 civilization, then things are not so absolute.


    Because level 0.99 civilization actually has the most basic space war capability, and can also attack enemies in nearby space from the planet itself.


    Therefore, in fact, if a civilization that has just entered a first-class civilization plays against a 0.99 civilization, the victory or defeat is not certain.


    .....


    In fact, it is precisely because mark knows very well the gap between their x aerospace company and Tiangong technology that he understands more what it means to hold Tiangong technology.


    Most importantly, for a capitalist and the capital giants behind x aerospace company, it doesn''t matter whether technology is technology or not, as long as there are enough profits.


    Therefore, the directors of their company''s board of directors unanimously confirmed that as long as Tiangong technology was reported, their company''s shares could definitely rise like a rocket, then their company''s market value would naturally increase significantly, and their wealth could definitely become rich overnight.


    As for the technological development of the bald eagle in aerospace, it doesn''t matter to such a private company. Moreover, today''s whole earth is no longer the earth before. Due to the threat of unknown alien civilization, human beings on the whole earth have begun to gradually move towards great integration. After all, once an alien civilization comes to the earth, Not only for one country, but for the whole human civilization. If the whole human civilization is not united, the earth will have no future.


    It is also mark''s proposal, which is of great benefit to both Wang Bing''s Tiangong technology and X aerospace company. Therefore, Wang Bin finally agreed to mark''s proposal and promised to sell special aerospace materials and his own version of pulse detonation rocket engine to mark''s x aerospace company.


    However, for various reasons, although Wang Bing promised to sell them the pulse detonation rocket engine, he only sold the first generation of his own version of the pulse detonation rocket engine. As for the second or third generation, Wang Bin has no plans to sell it to them, However, he also promised that Tiangong technology would sell the second or even third generation of its own pulse detonation engine to them for up to a year.


    For other engines, such as ion medium rocket engine, isotope rocket engine and controllable nuclear fusion engine of Tiangong technology, Wang Bin did not agree for the time being, because he obtained only 20% of the shares of X aerospace company, which is not enough for Wang Bin and Tiangong technology to sell the engine to them. After all, this is the core technology of Wang Bin''s technology, If Wang Bin does not have more than 50% of the shares of X company, he will not consider selling them.


    Even if he gets more than 50% of the shares of X aerospace company in the future, he will only consider isotope engines at most. As for controllable nuclear fusion engines and ionic medium engines, Tiangong technology will not consider selling them to other enterprises within a few decades.


    With Mark''s departure, within a few days, Wang Bin and their Tiangong technology began to supply various products to x aerospace company on a large scale, including various special aerospace materials, pulse detonation rocket engines, and other aerospace aircraft parts.


    With mature aerospace aircraft engines and aerospace materials and equipment, their company X has also made new aerospace aircraft very quickly. In less than two months, a new aerospace aircraft designed by their company has been almost assembled, and like before, this aerospace aircraft is also a medium-sized aerospace aircraft.


    Similar to the data of the previous aerospace aircraft, the newly manufactured aerospace aircraft has an air weight of 200 tons, a full fuel weight of 550 tons, and a maximum take-off weight of 700 tons. That is to say, the aerospace aircraft is OK. 150 tons of goods are sent into the earth''s low earth orbit. It can be said that such an aerospace aircraft is a real medium-sized aerospace aircraft, Its low earth orbit transportation capacity has reached the level of Phoenix II series.
