With the departure of Lei Yifei and others, Wang Bin returned to the mechanical experiment workshop, continued to cooperate with Yu Pingping and others, disassembled the Tiangong 001 UAV that had undergone a test flight, and fully inspected the internal parts.


    Although the internal conditions of the UAV are basically very good after testing, and there are no major problems, this does not mean that the UAV is very perfect.


    There are still many deficiencies, so Wang Bin and Yu Pingping also began to modify some places on the UAV.


    Of course, the internal inspection and improvement of the UAV can not be completed in one day or two. Therefore, when disassembling and improving the UAV, Wang Bin will go to the aerospace engine laboratory as usual to inquire about the engine production. At the same time, he will enter the science and technology mall every day, Sell some of their Tiangong technology products to earn energy coins.


    After all, Wang Bin wants to buy a lot of technologies from the system. Even if Wang Bin has saved more than 100000 energy coins since this time, this little energy coin is still far from enough for those real high-end technologies in the system, and even a slightly better technology can''t afford to buy.


    Of course, these energy coins in his hands, in fact, in the science and technology mall, can still buy many less complex technologies and many basic material technologies whose technical level will not exceed the scientific and technological level of human civilization.


    However, compared with other technologies, what Wang Bin wants most at this time is actually the manufacturing technology of chip processing equipment.


    And because Wang Bin already had copper based superconducting material technology in his hands at this time, his idea of chip production equipment has changed.


    Previously, he just wanted to buy ultra-high precision manufacturing equipment for ordinary chips, such as extreme violet high-precision lithography machine. However, his manufacturing technology for such production equipment is no longer so urgent. After all, the chips produced by using such equipment are only ordinary silicon-based chips.


    Not to mention anything else, only the chip silicon required by the chip is a big problem. Therefore, if he wants to manufacture silicon-based chips, he must first solve the problem of silicon for chips, and the price of the equipment for producing silicon for chips in the system is also very high.


    Even if Wang Bin has hundreds of thousands of energy coins in his hands, he can''t afford such equipment at all.


    If we add a complete set of technologies such as lithography and etching machines needed to manufacture chips, even if Wang Bin has millions of energy coins in his hands, he can''t afford to buy them.


    In addition, the manufacturing of silicon-based chips has basically been monopolized by foreign manufacturers in terms of patents. Therefore, if Wang Bin wants to manufacture ordinary silicon-based chips, they are bound to touch the patents of foreign manufacturers in these aspects, and things will become very annoying at that time.


    So Wang Bin turned his attention to higher-level chip technology, that is, superconducting chip technology and copper based superconducting chip technology.


    After all, now Wang Bin has copper based superconducting materials in his hands, so as long as he has manufacturing equipment, he can produce superconducting chips.


    Secondly, in terms of patents, as long as Wang Bin buys copper based superconducting chip technology from the system, there will be no patent problem in this regard. On the contrary, he can apply for key technology patents and even set patent traps.


    Most importantly, in the mall, the technology of copper-based superconducting chip manufacturing equipment is actually cheaper than that of ordinary chip production equipment. All the technologies of nano-scale superconducting chip production equipment add up to less than 1.5 million energy coins. Even with the whole set of technology of copper-based superconducting chips, The price is less than five million.


    In addition, as the core components of computers, mobile phones and so on, the chip is naturally very important in terms of performance, and the performance parameters of superconducting chip are definitely not comparable to ordinary chips, so Wang Bin at this time has put his eyes on superconducting chip technology.


    At the same time, Wang Bin''s Tiangong technology has also begun to make preparations in this regard, for example, recruiting talents in chip R & D and equipment manufacturing.


    Chip manufacturing is not a simple thing. Even for the manufacturing of copper based superconducting chips, there is a system that can instill various technical knowledge of manufacturing into Wang Bin''s mind. Relying on him alone, it is impossible to manufacture chip equipment in a short time.


    Therefore, it is necessary to have a strong R & D and manufacturing team. It is precisely aware of this problem that Wang Bin began to recruit talents in this field early, and they have also made certain achievements in this field of talent recruitment during this period of time.


    Not to mention anything else, Wang Bin has recruited dozens of chip design talents. However, this is still far from enough for Wang Bin. At the same time, in terms of software, they have also recruited nearly 100 people.


    After all, compared with hardware design talents such as chips, software talents are undoubtedly much easier to solve.


    In addition to this aspect, the test run of aero-engine has been completed. At this time, the 300 hour test run of the other seven engines of Tiangong technology by Wang Bin has also been completed, and the testing work has been completed. Next, the life verification test run of the engine must be prepared.


    That is, the next 500 hour test run, but Wang Bin knew very well that according to the current situation of these engines, the 500 hour test run was actually just a small test.


    In Wang Bin''s expectation, the first maintenance time of this engine must reach at least 5000 hours before it is qualified. If it does not reach 5000 hours, it will definitely fail for Tiangong technology!


    "Professor poke, what about the engine I sent over?" thinking about this, Wang Bin came to their aerospace engine laboratory of Tiangong technology. After finding Professor poke, he asked her.


    Yu Pingping, Jia Jie and others did not understand the engine at all, so after the test flight of Tiangong 001 UAV, Wang Bin and others disassembled the engine and sent it to Professor Zhang for testing.


    "Mr. Wang! There is no problem with the engine. It''s in good condition!" Professor poke said happily.


    Testing on the test bench is totally different from testing on the aircraft. Now, since this engine has no problems on the UAV, even during the flight test, it performs very well, and its data are very eye-catching, which proves that the performance of this engine is absolutely excellent, and it also proves that, They made many modifications to the engine without any problems.
