"Mr. Wang! The aircraft that is assembling the keel is the first aircraft designed by our Tiangong Technology Institute. According to your requirements, Mr. Wang, our aircraft can not only perform transportation and other tasks, but also perform tactical bombing tasks.


    However, in terms of the flight speed and altitude of the aircraft, the aircraft can not meet the requirements expected by President Wang. It is also the double two standard, because according to our calculation, if you want to meet the double two standard, the aircraft must be equipped with at least three tg-wsx1 engines. Of course, three tg-003 turbojet engines can also be used.


    However, if this is done, the performance of the aircraft will be greatly reduced, especially in terms of transportation capacity and carrying capacity. According to our estimation, it will be shortened by at least half.


    In this way, the practicability of this aircraft will be greatly reduced. After all, as a dual-purpose aircraft for transportation and bombing, if the range and carrying capacity are too small, how useful is it even if the speed and ceiling are too large. "After entering the workshop, Professor Dai said to Wang Bin.


    After listening to this, Wang Bin nodded and said nothing. After all, when the aircraft was designed and finalized, Professor Dai and others had already shown Wang Bin the design drawings of the aircraft and the performance of the aircraft. After obtaining Wang Bin''s approval, they began to manufacture parts. Otherwise, as a private enterprise, It is impossible to carry out such a big project without the boss''s nod.


    Wang Bin and others soon came to the keel of the phoenix-1 aircraft under assembly. Wang Bin carefully lifted a large number of the keel of the aircraft.


    Obviously, the keel of the aircraft is not made of aviation aluminum or titanium alloy. On the contrary, the keel of the aircraft is made of various steels that are not commonly used on the aircraft.


    Of course, these steels are not ordinary steels, but are made of special steels newly developed by Tiangong technology. This kind of steel is not only excellent in various properties, such as heat resistance and oxidation resistance. Even compared with titanium alloy, many properties are much higher, At the same time, in terms of weight, this steel is also very light, reaching the same level as aviation aluminum.


    It is this kind of special steel that has far more properties than aviation aluminum and other materials. They will use this steel as the keel of the aircraft with Tiangong technology.


    Although the assembly of the keel has entered the final stage, the workers who assembled the keel did not neglect it, but conscientiously completed the work in their hands. Even Wang Bin and his arrival were not found by these workers.


    And some people will conduct multiple inspections after installing a keel. If they find that the installation is not in place, they will immediately remove the keel and reassemble it.


    Because as soon as the technicians, they know very well that sometimes a small problem may cause major accidents, such as the crash of Northwest No. 6 aircraft.


    Of course, such an important assembly work naturally has a person in charge. After all, Professor Dai is only the general person in charge of the plane, but he can''t get together and manage everything by himself. In addition, the professor''s grade is not small. Even if he wants to manage by himself, he doesn''t have the energy.


    "Professor Dai! How is the keel assembly of this aircraft? Is it going well?" Wang Bin turned and asked Professor Dai next to him.


    "Mr. Wang! Although there are many difficulties in the assembly of aircraft keel, for example, technicians are unfamiliar with aircraft manufacturing, these difficulties are not major problems. Just check and correct them more.


    If everything goes well, the keel assembly of our aircraft can be completed in these two days, and then the aircraft can enter the final assembly stage. "


    After listening to Professor Dai''s words, Wang Bin nodded and asked Professor Dai again: "Professor Dai! In terms of other systems of the aircraft, especially the equipment that Tiangong technology has not been able to produce by itself for the time being, have you contacted the relevant manufacturers, and do these manufacturers have any information about when these equipment will be delivered?"


    Wang Bin knows that after the keel mechanism of the aircraft is assembled, the next thing to be done is the installation of various subsystems of the aircraft, such as the avionics system and airborne equipment system of the aircraft.


    The aircraft will not be covered and painted until all these works are installed.


    "Mr. Wang, don''t worry. We have contacted relevant official manufacturers and scientific research institutions for relevant equipment and subsystems. At the same time, for relevant electronic equipment, I have also provided relevant manufacturers with chips produced by Tiangong technology to ensure the safety of aircraft electronic equipment." Professor Dai said.


    Wang Bin looked at the workers who were seriously installing the keel in front of him. He was very pleased. Although most of these workers assembled the aircraft for the first time, some technicians were transferred from the engine assembly workshop before, so although they were unfamiliar, they strictly followed the assembly process requirements, The aircraft keel is being assembled.


    They who have assembled the aircraft engine clearly know that the assembly of the aircraft keel can not be careless. Like the previous assembly of the engine, they have strict requirements. Not only can there be no deviation in the assembly parts, but even the screws and nuts have sequence, and they also have process requirements in terms of tightness.


    Of course, when installing these keels, these workers should carefully inspect each keel that has been processed and will be assembled before installation. If there is no problem, they will install it. If they find a problem, even a small pit or depression, they will directly put this part aside, Scrap directly.


    In the following days, Wang Bin and Professor Dai were in the final assembly workshop, and the assembly process of the aircraft was much faster due to Wang Bin''s participation.


    In just two days, the keel of the plane was installed.


    With the completion of the keel installation, the technical workers immediately sent the keel to another workshop with a smaller area but more than 100 meters square for docking and painting.


    Yes, this workshop, which is smaller than the final assembly workshop, is the main painting workshop for their Tiangong technology aircraft manufacturing, and most of the equipment in the workshop is developed by their own Tiangong technology machinery R & D laboratory. Even if they do not have the strength to develop, they are also purchased by Wang bin from the technology mall.


    Therefore, this workshop is very advanced, with a high degree of digitization, automation and intelligence. After this huge aircraft keel was sent to this aircraft, all the painting and coating of the keel was completed in just five days, and the keel was sent to the general assembly workshop again.
