As Wang Bin''s words fell, Du Haili, who was on the other end of the phone, was in a good mood. After all, the biggest problem in front of his company has been solved by Tiangong technology. He is full of confidence in the next test flight of the helicopter that his company is developing.


    Of course, Du Haili still knows the power of the helicopter engine. After all, Du Haili''s Kunlun company has been running outside for so long for the engine, and he is very clear about the power requirements of the engine.


    He thought about it. At this time, Kunlun company has not obtained the approval to buy the second battery, so for the time being, their company can only buy the first battery, that is, the engine with an output power of 100 kW.


    That means that the output power of the engine purchased by their company must not exceed 100 kW.


    Of course, if the output power is only 100 kW, it is not enough for a helicopter weighing several tons, so a helicopter cannot be just an engine.


    According to the data of their company''s designers, the power of their engine should be at least 500 kilowatts.


    In other words, they must use linkage scheme to solve the problem of insufficient power of a single engine.


    The single power of the engine they passed is 100 watts, which means that the Kunlun helicopter of their company needs at least five engines to make the helicopter have better flight performance. However, for the sake of insurance, he thinks it should be equipped with six engines.


    Thinking of this, he continued to ask Wang Bin, "President Wang doesn''t know what the volume of the 100 KW electric engine you developed is, and whether you can directly adopt the linkage method."


    "Mr. Du, please rest assured that the 100 kW engine developed by our Tiangong Technology Institute is not large. The length of a single engine is about 30 cm and the diameter is only 12 cm.


    Based on the size of your helicopter, I can assure you that it will not be a problem if there are ten helicopters and eight helicopters. At the same time, if President Du needs the way of multi-channel linkage, there will definitely be no problem, "Wang Bin said.


    For the electric engine with high power and small volume, that is, the motor, Wang Bin is still very confident.


    After all, Wang Bin''s Tiangong technology has copper based superconducting materials. It is not difficult to develop high-power motors. As long as the coils of ordinary motors are replaced with superconducting coils, the power of motors can be greatly improved.


    Du Haili, after listening to Wang Bin''s words, felt more relieved.


    So after hanging up, he came to the R & D Department of Kunlun company with a happy mood and told the R & D personnel of their company.


    After listening to Du Haili''s words, the R & D personnel of their company were also excited on the spot. After all, Du Haili was very oppressed, not to mention the boss of Kunlun company, even as R & D personnel.


    Now, with high-performance batteries and high-performance motors, their company can finally get rid of the constraints of foreign aeroengine manufacturers and finally develop more advanced engines without scruples.


    "Mr. Du! It''s great. With the battery and engine of Tiangong technology, we don''t have to redesign our helicopter. We just need to optimize our original drawings to make it more suitable for electric drive.


    However, Mr. Du, I hope you can submit your application for purchasing the second-generation battery of Tiangong technology as soon as possible. As long as you can pass and obtain the second-generation battery, the weight of our helicopter can be further reduced.


    At the same time, the load capacity and other performance can be further improved, which is absolutely very important for our company.


    More importantly, if we have a motor and battery with an output power of 500 watts, we can also start to design and manufacture larger and heavier medium and large helicopters, which is definitely an important way for our company to improve its strength. "After Du Haili and their R & D personnel said this, the head of their company''s laboratory, After calming his mood, he said to Du Haili seriously.


    Du Haili also nodded heavily. As the boss of Kunlun company, Du Haili knew more about the importance of Tiangong technology''s batteries and motors to their company.


    So he secretly decided that Kunlun company must have a good relationship with Tiangong technology, even if it paid a certain share.


    On Wang Bin''s side, after hanging up Du Haili''s phone, Wang Bin didn''t have much fluctuation in his heart, because he had expected that Du Haili would not have any good results when looking for foreign aero-engine manufacturers as early as the last test flight of Kunlun company in the test flight field. In the end, Du Haili would still find their Tiangong technology.


    At the same time, Wang Bin thought that now Tiangong technology has developed the first generation superconducting battery and the second generation superconducting battery for such a long time, so it is time for them to start developing the third generation superconducting battery.


    In the following days, Wang Bin stayed at the headquarters of Tiangong technology. Of course, from time to time, Wang Bin also went to various laboratories to see the progress of various projects.


    "Mr. Wang! Good news! The 5000 hour life test run of tg001 turbojet engine of our company has been completed. All ten tg001 engines are in good condition without any accidents.


    Professor Chua and others have also tested the interior of the engine. The internal situation is beyond the expectation of Professor Chua and others. According to Professor Chua''s estimation, even if it runs for another one or two thousand hours, it will not be a problem at all. "In Wang Bin''s office, Wang Xu came in from the outside with a smile and said happily to Wang Bin.


    "What! The 5000 hour life verification test run has been completed, great." Wang Bin said happily.


    We should know that there are many R & D projects being carried out by Tiangong technology, but among these projects, the project that Wang Bin pays most attention to and invests most energy is the aeroengine project.


    After all, from the beginning, Wang Bin has determined the development direction of science and technology they provide, that is, the direction of aerospace. As for others, they actually serve these two directions.


    Now their company''s first aero-engine, tg001, has finally completed the life test of 5000 hours, which is definitely a milestone for this engine. After all, even if it is an aero-engine around the world, there are only a few engines whose life can reach this level.


    After all, this is a 5000 hour life test! This also proves that the performance of tg001 engine has definitely reached the top in the world.
