You should know that the previous introduction is only the vertical takeoff and landing aircraft using the fuel version. If it is the electric driven version, although it may be slower in speed and lower in flight altitude, it can be greatly improved in range and load capacity.


    After all, if you use a fuel engine, you have to load a lot of fuel inside, but if it is an electric version, you can only carry enough batteries on the plane.


    "Mr. Wang! We are looking forward to the performance of this aircraft if we can have a test flight!" Mr. Qiu said impatiently.


    Then, in the witness of the crowd, the aircraft was first pulled out of the workshop by the tractor and came to the airport. At the same time, the ground crew also began to inspect the aircraft.


    At this time, President Qiu suddenly said to Wang Bin: "President Wang! To be honest, we are all looking forward to your Tiangong technology aircraft, but President Wang, if you start to officially produce this aircraft in the future, can you produce more fuel versions and less electric versions!"


    "What! Is there any problem with the electric version? Or is the electric version not as good as the fuel version in terms of efficiency cost ratio?" Wang Bin said with some doubt. After all, this aircraft has not even started the test flight. President Qiu said this, which made him puzzled.


    "No! Mr. Wang! This is not your Tiangong technology problem, but our official problem.


    Because with the large number of electric aeroengines launched by Tiangong technology, these engines can not only be used in aircraft, but also in cars, especially for heavy trucks, such as dirt trucks. After all, your engine has enough power to drive dirt trucks and use electricity , more economical.


    It is precisely because there are a large number of electric aircraft and electric vehicles in China, especially electric aircraft and large electric vehicles. The power consumption is very huge. Neither electric aircraft nor electric heavy vehicles basically have the ability to generate electricity by themselves, and they all need to use the power grid to charge.


    This has directly led to a substantial increase in our demand for electricity. Now some of the official power grids are operating at full load. Although now the authorities have realized this problem and started to build a large number of power stations, they can''t keep up with the consumption for a while, especially our military.


    So in order to ease the power shortage, we''d better make more fuel first. If the power shortage is alleviated, we''ll produce the power version. "


    "What! The power is tight. I remember that in recent years, we have built a lot of large-scale power projects, and even a new generation of nuclear power is under construction.


    In addition, there are many power generation projects in the central and western regions, such as solar power plants and wind power plants. I even heard that there is a lot of spare power in many parts of the central and western regions. Why is there a lack of power? "Wang Bin asked.


    "Mr. Wang, what you know has long been a thing of the past. The current situation is that power is tense everywhere. Even this situation is not only for us, but also abroad," Mr. Qiu said.


    After listening to President Qiu''s words, Wang Bin also sank. After all, the current power problem is indeed a big problem.


    At this time, Wang Bin suddenly thought that he really has the technology to solve the power problem. Even as long as he has these technologies, many energy problems can be solved. That is, the controllable nuclear fusion technology or controllable cold nuclear fusion technology he obtained from Tony very early.


    However, he did not tell president Qiu, but wanted to tell president Qiu about the technology after realizing the technology.


    But now is not the time. Wang Bin is going to wait until the construction of the desert base is completed and carry out research and development there to realize this technology. After all, this technology is too important for a country to be careless. If it is put here, once this technology is discovered, there will never be peace.


    During the chat between Wang Bin and President Qiu, the completion of the plane has been completed.


    Then Professor Dai came up to Wang Bin and said, "Mr. Wang, the aircraft inspection is completed and the first test flight can be carried out. As long as there is no problem with this test flight, then the test flight of load and other subjects can be carried out."


    Professor Dai didn''t feel nervous in the process of speaking. After all, Tiangong technology has been very mature in the process of aircraft design, manufacturing and flight test. Therefore, both Professor Dai and Wang Bin believe that the aircraft they designed has absolutely no fatal problems.


    After listening to Professor Dai, Wang Bin nodded and said, "then start the test flight!"


    With Wang Bin''s nod, Professor Dai also informed the tower and the pilot.


    Soon, the two turbofan engines on the wing also changed the angle and became vertically downward. At the same time, two vertically downward electric fan engines also appeared at the wing roots on both sides.


    And with the operation of the aircraft crew. These engines, for the first time, began to work, and the engine speed was getting faster and faster.


    With the work of the engine, a large amount of air was sprayed to the ground, and Wang Bin and others were staring at the plane that was about to take off.


    With the increasing working speed of the engine, the air flow naturally becomes larger.


    Finally, when the thrust generated by the engine slowly exceeds the weight of the aircraft, the aircraft begins to rise steadily and slowly, and with the increase of engine thrust, the rising speed is faster and faster.


    However, when the altitude of the aircraft reached about 500 meters, Wang Bin and his colleagues clearly saw through the telescope that the angle of the main engine of the aircraft began to change, and the aircraft no longer went up vertically, but began to fly forward.


    When the engine angle of the aircraft returns to the original angle, the speed of the aircraft is very fast, and other downward engine nozzles on the aircraft also begin to close. At this time, the aircraft looks no different from other ordinary aircraft.


    When everyone saw that the plane successfully took off vertically, everyone clapped their hands. After all, it was a successful vertical take-off!


    This is definitely a huge achievement. At the same time, it also shows that Tiangong technology has successfully mastered the vertical takeoff technology. If they have mastered this technology, it will be much easier to develop the vertical takeoff technology in vacuum environment in the future.


    Of course, the vertical takeoff and landing aircraft designed and developed by their Institute of Tiangong technology is more excellent than the same technology abroad. First, the gap in tonnage, second, the gap in speed and range, and finally, the gap in safety and intelligence.


    It can even be said that the VTOL aircraft of Tiangong technology can completely crush foreign products of the same type in all aspects of performance.
