Just when Wang Bin and his team assembled all the modules of the UAV and prepared to start the test flight, which Kunlun company''s helicopter had been transported to a helipad not far from Wang Bin and unloaded.


    At this time, a chubby young man in Kunlun company''s work clothes looked at Wang Bin.


    Originally, the people of their Kunlun company didn''t care much about Wang Bin and them, but when they saw Wang Bin''s such a huge UAV and chief engineer Lin wearing 969 overalls next to Wang Bin.


    He immediately showed an excited look on his face, walked quickly towards Wang Bin, held out his hand and said to chief engineer Lin: "Isn''t this chief engineer Lin of 969 group? Hello! Hello! Chief engineer Lin, your 969 group, is also conducting flight test today! It seems that we haven''t received any notice from relevant parties before!"


    Generally speaking, although the test site is open to the outside world, if the 969 group wants to conduct aircraft test flight, they will take the lead in notifying the staff of the test site and temporarily close the test site. They will not open to the outside world until they complete the test flight. After all, 969 group is a military industrial unit. Naturally, they have developed the test site The walker must also be kept confidential.


    However, he found that chief engineer Lin and his crew were conducting a test flight today and did not keep it secret. The most important thing is that on the runway where chief engineer Lin and his crew are located, the UAV that is quietly parked does not seem to be a civilian UAV, which makes him a little strange!


    "Hello! Mr. Du, I didn''t expect your helicopter to test fly today! Let me introduce you to the one next to me."


    "This is Wang Bin, President Wang of Tiangong technology. He is also a new member of our country''s private aircraft manufacturing industry. Most importantly, President Wang''s Tiangong technology has a very strong scientific and technological strength and R & D team. If you can have a good relationship with President Wang, maybe president Wang''s Tiangong technology can solve the biggest problem of your company''s aircraft."


    After that, he said to Wang Bin: "Mr. Wang! This is Mr. Du Haili, one of the largest private aircraft manufacturing enterprises in our country!"


    "Hello, Mr. Du!"


    "Hello, Mr. Wang!"


    Then they both stretched out their hands and shook hands with each other.


    Then Du Haili asked chief engineer Lin of 969 group again: "chief engineer Lin, this UAV must be a new UAV developed by your 969 group!


    This plane is really beautiful. I don''t know when our Kunlun group can develop such a beautiful plane! "


    While talking, Du Haili''s eyes were full of envy.


    Although the plane parked on the runway is not a manned plane, as the boss of an aircraft manufacturing company, he certainly understands the difficulty of manufacturing such a large jet UAV. Even if it is a UAV, its difficulty is beyond the ability of their company.


    Of course, if the plane is just a large propeller UAV, it is still possible to make it with the ability of their company.


    "Mr. Du! In fact, this UAV was not developed by our 969 group, but manufactured by the next Mr. Wang and his company. Besides electronic components, all other things of this UAV are designed and manufactured by themselves, including a series of core equipment such as the engine of this UAV!" Chief engineer Lin smiled and said to President Du.


    "What! Chief engineer Lin! You''re not kidding! This UAV is not owned by your company, but by President Wang and Tiangong technology. Besides electronic components, other UAVs are developed and produced by themselves, including engines!" Du Haili couldn''t help shouting after hearing chief engineer Lin''s words.


    Because chief engineer Lin''s words really surprised him. Even the engine was made by themselves. You know, this is the engine of a large UAV!


    According to the large-scale jet UAV developed by previous official units, the engines used are basically manned jet aircraft engines


    In other words, the engine used on the UAV can also be used on a real manned aircraft, which is what shocked him most.


    After all, as an aircraft manufacturer, he is very aware of the difficulty of manufacturing aeroengines. In fact, the helicopter they are preparing to test fly has failed several previous test flights. The most important reason is also on the engine.


    In fact, at the beginning, when they designed the aircraft, they also prepared their own engine. Of course, they did not have the ability to develop a real turboshaft aeroengine, but prepared to use a piston engine as the power of the helicopter.


    But their company completely ignored the difficulty of developing aeroengines, even the piston engines used in helicopters.


    Therefore, when their helicopter was successfully designed and ready for manufacture, they found that the piston aeroengine they developed was still at the beginning of the project, there was no progress at all, and there were many difficulties. It was impossible to develop it for a while.


    Therefore, in the case of no way, their company can only turn to other domestic engine production companies to buy their products to make their own helicopters.


    However, even so, when they built the helicopter and began to test fly, they found that even if they had used the products produced by domestic mature engine companies, there were many problems.


    At the same time, the performance of the aircraft can not meet the requirements of their design, which makes them very upset.


    You know, since the aircraft was manufactured, it has gone through more than ten test flights, but more than ten test flights ended in failure. At the last test flight, it was due to the engine that almost destroyed the aircraft and killed people.


    It is for this reason that they stopped using the engine immediately after the last test flight, and instead purchased the piston aeroengine at a high price from foreign manufacturers.


    Of course, their company has not stopped the engine R & D, and now continues to invest a lot of money, manpower and material resources, but the progress of R & D is still very slow.


    It is precisely because of this that they know more about the difficulty of developing an aeroengine, even piston type, than other private enterprises.


    However, in front of him, Tiangong technology, which he had never heard of, successfully developed a jet aeroengine, which didn''t surprise him!
