According to the laboratory data, the applicable temperature range of this metal rubber is: the minimum normal use temperature is minus 220 degrees, the extreme low temperature use is minus 240 degrees, the maximum normal use temperature is 2106 degrees, the maximum extreme high temperature is 2302 degrees, and the melting temperature is 2613 degrees.


    Therefore, he is very confident in the metal rubber he developed. At the same time, the manufacturing cost of the second generation of metal rubber is higher than that of the first generation, but it is not much higher, which is about the same as that of ordinary rubber.


    "Yes, the success of our aerospace test flight also represents that we, Tiangong technology, have officially had the ability to manufacture aerospace aircraft in China, and that we have obtained tickets for the great Aerospace era.


    If there is no accident, it won''t be long before we can officially enter the era of great aerospace. Of course, this also means that our aircraft will also enter mass production.


    However, all this is based on the fact that we can solve the problems we encounter now. If we can''t solve them, it''s no use saying more, "Professor Zhang nodded.


    "Mr. Wang! Please rest assured! The metal rubber developed in our laboratory is absolutely competent as the tire material of aerospace aircraft. After all, where is the performance of the metal rubber we developed? According to the experimental data..." then Xiao told Wang Bin the performance of the metal rubber developed in their laboratory.


    After listening to Xiao Xiao''s performance of metal rubber, Wang Bin was also very surprised. After all, after just completing the test flight, he found that the aircraft''s load wheel could not use rubber as material, his heart was still very anxious.


    After all, the load wheel used on the plane is already the best aircraft tire, but even so, the tire burst.


    Therefore, he was thinking that if there was no way, he could only use the load-bearing wheel of mechanical structure first.


    But that will undoubtedly greatly increase the weight of the aircraft''s load-bearing wheel and the overall weight of the aircraft. After all, the weight of each mechanical tire is at least hundreds or even thousands of kilograms, which will definitely greatly increase the flight cost of each flight for an aerospace aircraft that needs precise calculation for every gram.


    But now with this metal tire, there is no such problem. Even because the metal rubber material itself is lighter than ordinary rubber, it can greatly reduce the weight of the aircraft and enable it to carry more goods, which can greatly improve the cost performance of each flight of the aircraft.


    In the following days, Wang Bin, Professor Zhang and Professor Zhang stayed in the laboratory every day to manufacture this metal rubber.


    At present, there is no other way to make this metal rubber except in the laboratory.


    After all, Tiangong technology doesn''t have a production line for this kind of metal rubber, so intelligent manufacturing is in the laboratory. Fortunately, Wang Bin has begun to establish a production line for this kind of metal rubber. According to the plan, a large-scale production line for this kind of metal rubber can be established and completed within one month.


    A few days later, the load-bearing wheel made of this metal rubber material was installed by the manufacturer on the Phoenix kt1 aerospace aircraft and began to prepare for another test flight.


    On the runway, Wang Bin, Qiu Zong and others quietly watched the ground crew check the overhead plane and chat from time to time.


    "Mr. Wang! Is this the metal rubber material developed by your Tiangong science and Technology Institute? It''s really very advanced. Apart from other properties, it will explode ordinary rubber only in terms of applicable temperature!" Mr. Qiu said, looking at the black metal colored tire of the aerospace aircraft.


    "Yes! Mr. Qiu! This is the metal rubber developed by our Tiangong Technology Institute. Although the test data in the laboratory are very good, it is a very ideal substitute for ordinary rubber.


    However, because this material has just been developed and has not been applied on a large scale, many data are not very accurate. You must use it before you can know the specific data. "Wang Bin nodded and said.


    "It''s said that the production cost of this metal rubber is very low. I don''t know if it''s true, Mr. Wang. If it''s true, I think many equipment in our military can use this material.


    I don''t know when Tiangong technology can produce this material on a large scale? "President Qiu said.


    "Don''t worry! Mr. Qiu, Tiangong technology is already building a large-scale production line of this material. If there is no accident, it can definitely carry out large-scale mass production within the year," Wang Bin said!


    At this time, old Qin was also very happy to look at the load-bearing wheel of the aerospace plane and said to Wang Bin: "Mr. Wang, your metal rubber is definitely a very good material. If we had this material earlier, many of our previous rocket launch failures would not have happened."


    While they were chatting with Wang Bin, the ground crew finally completed the inspection of the aircraft. At the same time, the crew were ready to complete and the aircraft was ready for another test flight.


    At this time, Wang Bin, President Qiu and old Qin are also continuing to chat, and they don''t feel nervous about the program at all.


    After all, a successful test flight has been carried out. Wang Bin and Qin Lao have great confidence in this test flight.


    Soon, after receiving the reply from the tower, the Phoenix kt1 space plane finally began taxiing under everyone''s eyes. After taxiing for more than 2000 meters, it took off and went straight into space.


    With the Phoenix kt1 aircraft taking off again, Tiangong technology has once again become the focus of the whole world. After all, due to the success of the last test flight, now the whole China and the whole world, who doesn''t know that Huaxia Tiangong technology has developed an aerospace aircraft that can fly directly from the ground to space.


    Of course, the success of the research and development of aerospace aircraft by Tiangong technology has also greatly stimulated the major countries in the world, especially those countries that have made great achievements in aerospace.


    For example, owl country has successfully developed an aerospace aircraft due to the influence of Tiangong technology. Although they have also had an aerospace aircraft R & D plan before, the process is not fast. Therefore, in order to speed up the R & D progress, they hope to take out the corresponding aerospace aircraft in the shortest time and directly allocate hundreds of billions of financial allocations for R & D.


    The situation of Arctic countries is similar. Although the economic situation of Arctic countries is not ideal, they still took out $50 billion or $60 billion to develop their aerospace aircraft.


    In addition, they also took out the drawings of the snowstorm before the disintegration of the Federation again, hoping to design an aerospace aircraft based on this.


    There are also the western continent space agency, the island space agency and the elephant space agency, which have successively launched their own space shuttle program and invested huge funds.


    After all, this is about the future of the country and the nation. No one dares to slack off. At the same time, at this time, no one at home or abroad is saying that developing the aerospace industry is a waste of funds and resources.
