After listening to Qi Wenbo''s words, Wang Bin did not hesitate, but directly agreed to his request. After all, even if he did not say, in fact, Wang Bin and Tiangong technology also have corresponding plans. After all, their Tiangong technology plans should be able to produce a series of engines from the engine of small aircraft to the engine of large passenger aircraft.


    So he readily opened his mouth and promised, "OK! Manager Qi, I will hand over this matter to the corresponding designers of our company in the next two days. Your company will just wait for the good news of our company."


    "By the way, Wang Bin, as far as I know, your Tiangong technology has developed high-performance batteries and matching helicopter electric engines.


    I wonder if your company has developed a matching fixed wing electric propeller engine.


    If so, our company also wants to purchase a batch and try to change some of our previous propeller airliners into electric ones.


    After all, fuel engine and electric engine can not be compared in terms of cost performance.


    Therefore, if the fuel engine can be changed into an electric engine, the flight cost of the aircraft will be greatly reduced.


    In addition, the cost of maintenance, reliability and security will also be greatly reduced, which is absolutely necessary for our customers. I think once successful, we will get a large order.


    "Manager Qi, I didn''t expect your company to be so well informed. Yes, our company has indeed developed two helicopter electric engines, and both have been tested for tens of thousands of hours.


    According to the test data, the failure rate and efficiency cost ratio of aviation electric engine are not comparable to fuel engines with the same power at all. It is only about one tenth or even one tenth of the price of fuel engine, and the difference will be more obvious if installed on the aircraft.


    After all, the fuel engine must also carry a bulky and space occupying mailbox in order to carry the fuel used by the engine, but after using electricity as the engine, so much space and weight will be completely liberated. After all, the volume and weight of the battery are far less than the fuel tank and fuel.


    Of course, so far, we only have two electric engines, but if manager Qi needs it, we can develop it for your company at any time.


    And can develop corresponding electric engines in a short time, that is, up to one month.


    Because the research and development of electric engine is not difficult, the speed of research and development is naturally much higher than that of fuel engine, "Wang Bin said.


    "Mr. Wang! That''s great. We''ll make a deal like this. After I go back this time, I''ll ask someone to send you the data of the electric engine we need. After you Tiangong technology develop the corresponding engine, our company will purchase it on a large scale, whether it''s fuel engine or electric engine.


    After all, if we can purchase domestic products, why should we buy foreign products at a high price and be stuck by outsiders! "Qi Wenbo said happily.


    After that, Wang Bin and Qi Wenbo, Wang Xu and Xiao Liu stood up and shook hands with each other. Then, everyone clapped.


    Obviously, Qi Wenbo and Xiao Liu were very satisfied with their Tiangong technology engine this time, and put forward on the spot, hoping to go to their Tiangong technology production workshop.


    So Wang Bin and Qi Wenbo and Xiao Liu spent an afternoon at their aeroengine manufacturer of Tiangong technology. It was not until more than four o''clock in the afternoon that they were sent out by Wang Bin.


    ...........


    After sending away Qi Wenbo and the two of them, Wang Bin immediately began to develop the engines they discussed with Qi Wenbo. After all, these engines themselves are within the scope of their R & D plan of Tiangong technology. Even without Qi Wenbo''s requirements, Wang Bin will develop them.


    The first is the R & D plan of the electric propeller engine. Wang Bin directly entrusted the task to the R & D Department of the electric engine. After all, with the ability of the R & D Department of the electric engine, Wang Bin fully believes that they will definitely develop the corresponding electric engine in the shortest time.


    Moreover, because the third generation superconducting battery of Tiangong technology has also been successfully developed and is ready for small-scale mass production, there is no need to do any restriction in terms of power, and it can be developed according to the power of fuel engine.


    Of course, in fact, even the electric engine R & D Department of their company now has a very heavy task at this time.


    However, their department is busy, not designing and developing electric engines for aviation, but developing high-power electric engines for ships.


    After all, the research and development difficulty of marine high-power engine is not a little worse than that of aviation electric engine. After all, the power of aviation engine is generally impossible to reach tens of thousands or even hundreds of thousands of kilowatts, but the larger the marine engine, the better.


    For those regional jet engines with smaller thrust and more fuel-efficient, Wang Bin is also ready to hand over these tasks to Professor Zhang. He believes that Professor Zhang will not let him down.


    ........


    When Wang Bin and his Tiangong technology were carrying out various R & D projects in an orderly manner, Qi Wenbo and Xiao Liu finally returned to their company, Donghai aircraft manufacturing company.


    The first thing they did when they came back was to prepare to report their achievements in Tiangong technology one by one to their superior, general manager Ma of Donghai aircraft manufacturing company.


    "Manager Qi, Xiao Liu, you''re back. What''s the situation of your visit to Tiangong technology this time? Has their company really developed advanced aeroengines? What''s the specific level? Can it reach the level of several generations of aircraft, the second generation or the third generation?"


    When Qi Wenbo and Xiao Liu just walked into the general manager''s office of their company, Ma Zhong, the general manager in the office, saw them and asked them urgently.


    Qi Wenbo was not surprised by the eagerness of their general manager Ma Zhongma. After all, high-performance aeroengines are too important for their company. Therefore, whether domestic companies have the ability to produce and how their performance is directly related to their company''s next strategic decision.


    "Mr. Ma! I''m about to report this to you! This time Xiao Liu and I went to Tiangong technology to check the situation of their company. It can be said that we have gained a lot. Their company has indeed developed engines with excellent performance. In the future, we don''t have to look at the faces of foreign engine giants, let alone worry about getting stuck." Qi Wenbo said happily to Mr. Ma Zhong.
