Of course, this is only the temporary plan of Wang Bin Tiangong technology. The real R & D progress depends on the R & D speed of Professor Poke''s laboratory.


    Time passed very quickly in the busy work of Wang Bin and others. In the twinkling of an eye, three months have passed. At this time, it has come to the new year.


    At the same time, in the new year, Wang Bin''s goal of Tiangong technology is naturally more huge, and the largest of them is Tiangong technology''s aircraft R & D projects and rocket and spacecraft R & D projects.


    Of course, Wang Bin is very pleased with the achievements of Tiangong technology in the field of aviation development in the past year.


    After all, in the past year, Wang Bin and Tiangong technology have made great achievements.


    First of all, naturally, in terms of electric engine, due to the low difficulty of electric engine research and development, coupled with the support of superconducting battery technology of Tiangong technology.


    Therefore, in the past year, Tiangong technology has developed more than ten models of electric engines, including the aviation engines of helicopters and propeller aircraft. At the same time, the power is also from low to high.


    At the same time, in terms of electric engine customers, Tiangong technology also talked a lot last year, and these customers who used electric engines were very satisfied with these electric aviation engines of Tiangong technology, and all said that they would continue to cooperate with Tiangong technology and continue to purchase Tiangong technology''s electric engines in the new year.


    Even some official manufacturers of helicopters and fixed wing propeller aircraft have great interest in the electric engine of Tiangong technology.


    This is especially true for the manufacturers of low-level trainer aircraft. After all, the efficiency cost ratio of fuel engine is too high, which leads to the high cost of training a low-level pilot.


    However, if the fuel engine is replaced by an electric engine, the efficiency cost ratio will be much lower. After all, for today''s China, electricity is only once.


    In this way, the cost of training a low-level pilot is much lower, and even the lowest can reduce the pilot cost of training a low-level propeller aircraft to less than six digits, which can definitely save a lot of pilot training costs.


    In addition, there are electric helicopter engines, especially high-power electric helicopter engines, which are also of interest to many official aircraft manufacturing companies.


    After all, these official helicopter manufacturers are different from private aircraft manufacturers. They basically have their own mature technology in helicopter manufacturing. Even the engine is not a big problem for them.


    Moreover, these official helicopter manufacturers are basically not so involved in the manufacture of light and small helicopters, and basically focus on medium and large helicopters.


    So they naturally care more about the high-power electric helicopter engine of Tiangong technology.


    At the same time, in the past year, in addition to its achievements in electric engines, Tiangong technology is a fuel engine.


    In this regard, Wang Bin is also very satisfied. After all, in the past year, Wang Bin and Tiangong technology have developed six aviation engines.


    That is, TG-001 turbojet engine, tg-002 turbojet engine, tg-s001 turbofan engine, tg-s002 turbofan engine, tg-s003 turbofan engine and tg-wsx1 small bypass ratio turbofan engine.


    At the same time, among these engines, three engines have entered the stage of large-scale mass production, that is, 001 turbojet engine, S001 large bypass ratio turbofan engine and S002 large bypass ratio turbofan engine.


    Although the remaining three engines have not yet entered the stage of large-scale mass production, they can also do small-scale mass production.


    In addition, in terms of customers, these engines are basically available. Needless to say, the customers of 001 turbojet engine naturally come from the military. After all, this engine has little use in civil use. After all, its economy is too low compared with turbofan engine.


    The second is the S001 turbofan engine, which not only has more customers in China, including military and military aircraft customers, but also has successfully entered the international market.


    Due to the efforts of the International Trade Department of Tiangong technology, the international customers of this engine are not only Yama airlines, but also Duojia international aircraft manufacturers, who have successively signed procurement contracts with Tiangong technology.


    The quantity purchased by these aircraft manufacturers is not low, and the largest one even directly issued a procurement contract for thousands of engines to Tiangong technology.


    All these international orders add up, and the number of engines ordered is as high as 3000.


    Of course, such a large number of orders can not be completed within one year. After all, if domestic orders are added, the number of orders for this engine alone is more than 5000. Therefore, even if Tiangong technology has more capacity, it can not be completed within one year. These orders are orders for three years, and the average engine to be delivered every month, About 200.


    After all, in addition to this engine, Tiangong technology has other models of engines to produce, so it is impossible to produce this engine in all production lines.


    As for the order quantity of S002 engine, there are also many. In addition to the domestic order quantity, there are also seven or eight hundred units, plus the three hundred units of Yama company, the total order quantity of this engine is nearly one thousand units.


    And these orders are different from the previous ones. Because the export of this engine must be approved by the official first, and the conditions are more demanding than the previous tg-s001 model, so up to now, although many aircraft manufacturers have submitted to the relevant departments that they want to buy S002 turbofan engine.


    However, in fact, only Yama airlines, a foreign aircraft manufacturer, has passed the application.


    In addition to these engines that can already be mass-produced, those engines that children can''t do can only be small-scale mass-produced engines. At this time, Wang Bin and Tiangong technology don''t intend to export these engines. At the same time, even if Wang Bin wants to export, according to the current situation, It is also impossible for the government to allow exports.


    After all, the technology of these engines is more advanced, higher performance, more strategic value, and the capacity is also very limited. Naturally, they are given priority to the official and domestic enterprises. Only when the domestic enterprises fully satisfy, will they consider the outlet of some civil engines.


    As for military engines such as 001, 002 and wsx1 engines, it is even more impossible to export them. After all, in terms of the performance of these engines, they are all the top military engines in the world. They are a sharp weapon of the country and can not be exported, even if they are friendly to China.


    Export will not be considered unless one day these engines have become second or even third rate products.
