The efficiency of Tiangong technology is definitely not comparable to that of the official. Just after Qin Lao left, the rocket technicians of Tiangong technology immediately began to move the launched rocket to the workshop dedicated to detecting the rocket situation, and began a series of inspections on the rocket.


    At the same time, in the rocket manufacturing workshop, in addition to manufacturing larger rockets, three Tiangong-1 launch vehicles are also being manufactured. According to the manufacturing speed, these rockets will be completed within a month and can be filled with fuel and launched at any time.


    At the same time, in terms of aeroengine, the production line of TG-001 engine has already been built. The production line of Wang Bin and tg-s001 turbofan engine has been completely completed and has been put into large-scale production.


    After all, in terms of engines, the most time-consuming thing for Tiangong technology is the production capacity of tg-s001 engine. However, with the new production line put into use, this phenomenon will be solved.


    Finally, the test run of Tiangong technology''s small bypass ratio turbofan engine. At this time, the test run process of small bypass ratio turbofan engine is very smooth. Although some small defects are found in the test run process, it does not affect the test run of the whole engine.


    At the same time, in order to put into mass production immediately after the test run, the production line of this engine has also been put into construction. After the test run of the engine is completed, this production line will also be put into production.


    However, different from those engines before, the production line of this engine has not been built, but only one is planned and built.


    However, the production line of this engine is much larger than that of other models of engines. The maximum production capacity will reach about 70 or 80 units per month, that is, nearly 1000 units per year, which is absolutely enough for this engine.


    After all, compared with the dual-use engine! The use of this engine is much smaller. At the same time, in terms of export, there is no need to think about this engine in the future. Therefore, in the future, the sales volume of this engine is doomed to be impossible. It can sell up to several thousand units a year, just like the large bypass turbofan engine.


    In addition to these engines, Wang Bin and Tiangong technology are also developing larger models of turbofan engines, including large bypass turbofan engines with greater thrust, that is, the engines used by real long-range and ultra long-range large intercontinental aircraft.


    However, compared with the research and development difficulty of the turbofan engine of the regional aircraft, it is obvious that the research and development difficulty of these big guys is higher and the research and development time is longer. Even if Professor Dai and others have obtained the data of the high thrust and high bypass turbofan engine purchased by Wang bin from the system, it is impossible to successfully develop it within the year.


    .......


    North Star.


    Wang Bin and Wang Xu have poked professors and others out of the plane.


    In fact, Wang Bin didn''t want to come to Beixing this time. After all, Tiangong technology is too busy due to various R & D tasks and big attitudes, but they have to come at the invitation of Wan Lao and WAN Lao''s superiors.


    The purpose of wanlao and others inviting Wang Bin to Beixing this time has already been told by Wang Bin, that is, because the engine of the domestic No. 6 bomber is a little outdated and is not up to the development of the times, they are ready to make a certain transformation of the engine of the No. 6 bomber, but there is no suitable engine yet.


    Although Tiangong technology has developed two turbofan engines, namely tg-s001 and tg-s002, these two engines are large bypass ratio turbofan engines and can not be used on unit 6. After all, the turbofan engine used by unit 6 is not large bypass ratio turbofan engine, but small bypass ratio turbofan engine.


    Of course, compared with the small ducted turbofan engine used in small aircraft such as fighter, it is still very different.


    Of course, Wan Lao and his colleagues also discussed how to install the tg-s002 engine of Tiangong technology on aircraft 6. Although the tg-s002 engine is a turbofan engine with large bypass ratio, it is not impossible to install aircraft 6 after a series of modifications.


    However, the cost of such transformation is very large. Not to mention the transformation of electronic equipment and other aspects, but only the transformation related to engine, its engineering quantity and technical difficulty are very large. It is even as good as redesigning a bomber of the same type.


    And although the significance of such transformation is not big for Wang Bin, it is very attractive for wanlao. After all, only after such transformation, the aircraft can immediately increase its bomb carrying capacity by about 30% and its range by about 50%.


    In this way, the maximum bomb load of this No. 6 aircraft can reach nearly tons, and its maximum range can also reach more than 1300km.


    In China, the new bomber is still under research and development. Although the research and development speed has been very fast, we still want to wait a long time until the new bomber is fully put into service. The most important thing is that even if the new bomber is put into service, it is absolutely impossible to equip too much at the cost of the new bomber, At that time, the bomber will still be dominated by No. 6.


    At the same time, when the new bomber has not yet been in service, aircraft 6 is definitely the main force of military bombers. At the same time, it will continue to play the role of long-range bombers. Therefore, it can be imagined that such performance after transformation is attractive to wanlao and others.


    Finally, after thinking about it, Wan Lao did not immediately decide to transform the No. 6 aircraft, but called the major domestic engine and aircraft manufacturers, including Tiangong technology, to discuss and see what way to transform the aircraft.


    That''s why Wang Bin''s trip to the north star.


    Subsequently, Wang Bin and Professor Zhang and others stayed in a hotel arranged by wanlao and others.


    However, just as Wang Bin and his colleagues had just walked into the hotel, someone suddenly called him and his voice was very familiar to Wang Bin.


    So he turned around and found that it was Wang Bin''s old acquaintance, Qiu Tuan, so he said, "Qiu Tuan, you''re here too!"


    "Well! After all, we must participate in such a big thing. After all, we are the end user of this fighter, so our opinions are also very important."


    Then he looked around and said to Wang Bin, "let''s go! President Wang and Professor poke, let''s go to the conference room inside and say that this is not the place to talk!"


    "OK!" after listening to Qiu Tuan''s words, Wang Bin also looked around, nodded, and walked with him to the interior of the hotel subordinate to the military.


    As for Wang Xu and others, they didn''t come because they knew very well that they were not qualified to participate in such a conversation.
