Of course, these foreign optical glass and optical lens manufacturers have no good way to China''s current market.


    After all, Tianyuan optics has firmly grasped the domestic market of China. If they want to enter, they must first face the encirclement and suppression of Tianyuan optics.


    But naturally, they can''t let the Tianyuan optical products of Huaxia enter the international market on a large scale. Even the company''s existing customers abroad should find a way to cut them off.


    Because once the company''s products begin to enter the international market on a large scale, the consequences they have to bear will be very serious. After all, there are countless examples in front of them.


    Not to mention anything else, it can be seen from the international high-end bearing market in recent times.


    But in fact, there is no good way for them.


    First of all, naturally, in terms of price, their products have no advantages at all. After all, Tianyuan optics''s similar products are much cheaper than them.


    In terms of quality, they also have a certain gap with Tianyuan optics. Finally, there are other things, such as the official of various countries. However, with the current strength of China, most countries will not rashly offend China because of this small matter, except for the white headed eagle.


    .......


    Wang Bin didn''t pay too much attention to the situation of Tianyuan optics after understanding the specific situation.


    After all, at this time, the 300 hour verification test run of the remaining seven turbojet engines in the aerospace engine laboratory of Tiangong technology has been completed, and the 500 hour and 1000 hour endurance test run will be carried out next.


    In addition, the first UAV produced by Tiangong technology will also be assembled and tested in the past two days.


    Therefore, he has no time to think about others. Compared with his subsidiaries, Tiangong technology is the focus.


    Wang Bin was busy and two days passed quickly.


    On the morning of the third day, in the mechanical test workshop, Wang Bin, Yu Pingping and others were carrying out the final assembly of a formed UAV. This UAV, named Tiangong 001 by Wang Bin and them, belongs to a single engine medium supersonic UAV. The maximum diameter of the UAV is only 1.5m, but its wingspan has reached 8m, The maximum length of the whole machine has reached 14 meters.


    In addition, according to the design data, the empty weight of the UAV is about 3 tons, the maximum takeoff weight is 16.7 tons and the maximum fuel load is 10 tons.


    In other words, the UAV''s full fuel bomb load is also up to more than three tons. If it is not full of fuel, its bomb load will be greater.


    At the same time, the UAV has a maximum speed of Mach 1.6, a maximum range of 20000 kilometers, a maximum flight altitude of 23000 meters and a maximum endurance of 20 hours.


    Because the UAV uses a new communication control system, the controllable range is not limited as long as it is on the earth. Even without network, navigation and radio, the UAV will not be disconnected or signal lost.


    It can be said that this UAV is definitely the world''s top UAV. If autonomous combat modules and various weapons are installed on this UAV, then this UAV is definitely a fighter with super combat effectiveness.


    With the UAV, with the efforts of Wang Bin and others, the last screw was installed. At this point, the UAV was finally installed and ready for indoor testing.


    Of course, since this UAV is a jet fixed wing UAV, it is naturally impossible to conduct flight test indoors, so the indoor test can only carry out some simple tests, such as various wing steering and so on.


    Although Wang Bin was unable to test the specific situation of the UAV indoors, he was not in a hurry. After all, tomorrow they will get up and go to the provincial test flight field of 969 group to test the UAV.


    At the same time, Wang Bin is also very confident about the test flight. After all, it took a lot of energy from Tiangong technology to develop it.


    Among them, there are not only the achievements of Yu Pingping and others, but also the achievements of Professor Zhang and Professor Dai.


    After a series of static tests, Wang Bin and others began to unload all the wings of the UAV, and loaded the UAV with Yu Pingping and others onto the truck that had already stopped at the door of their workshop.


    After all, for such a large UAV, Tiangong technology itself has not run for the time being. If it does not use trucks for transportation, there is no way to get the UAV to the 969 group in the provincial capital.


    The next day, Wang Bin, they set foot on the journey to the provincial capital 969 group early in the morning, and arrived at 969 group at about 9 a.m.


    At the gate of 969 group, Wang Bin naturally called chief engineer Lin first and was soon connected by chief engineer Lin.


    "Chief engineer Lin! I''m Wang Bin of Tiangong technology. I''ve brought our UAV to the door of your 969 group!" Wang Bin said after chief engineer Lin answered the phone.


    "OK! I''ll be right out!" then chief engineer Lin hung up.


    Soon, Wang Bin saw chief engineer Lin coming out of the gate of the branch of their 969 group, so he immediately got off and greeted him. As he walked, he smiled and said to chief engineer Lin, "chief engineer Lin! I''ll trouble you again this time!"


    Chief engineer Lin nodded and said to Wang Bin with a smile: "Mr. Wang, you Tiangong technology is really great! I remember that it has only been a few months since you started developing aeroengines!


    But in such a short time, you have successfully developed your own aeroengine and successfully conducted 300 hours of verification test.


    The most important thing is that you have developed such an advanced UAV in such a short time. It''s really amazing! "


    "Chief engineer Lin, you praised the efforts of our Tiangong science and technology researchers, such as Professor Zhang and Professor Dai. Without them, it would be impossible for Tiangong science and technology to have so many achievements in such a short time." Wang Bin said.


    "No! Mr. Wang! Although Professor Pao and Professor Dai do have extraordinary scientific research capabilities, without the capital and other investment of Tiangong technology regardless of cost, even if Professor Pao and Professor Dai have greater talents and ideas, they can''t have such great achievements in such a short time. Otherwise, Professor Pao and Professor Dai I won''t go to your Tiangong technology.


    By the way, let''s go to my office and sit down for a while. After I tell you what I''m doing, we''ll go to a small test flight field outside our 969 group for test flight. If there''s no problem, I''ll arrange you to go to the official test flight center for test flight.


    If there are no more problems, then your aircraft will have no problems in terms of production license and other certificates, and even orders should be available! "Chief engineer Lin said.


    After listening to chief engineer Lin''s words, Wang Bin nodded and walked towards the 969 group.
