Soon, Wang Bin, Qiu Tuan and Professor Zhang came to a conference room of the hotel and asked irrelevant personnel to leave. Qiu Tuan said, "President Wang, I think you must have known about the transformation of unit 6 this time. I don''t know whether it is necessary for you to transform unit 6 so quickly. After all, the shortcomings of unit 6 are too obvious.


    Even the latest modified version has a range of about 10000 kilometers, and there are some fewer bombs. The most important thing is that aircraft 6 is neither stealth nor supersonic. It is still very difficult to break through the enemy''s defense in war.


    If the transformation is carried out, although the amount of work will be very large, after all, it is only in the body transformation. If you want to install the lower tg-s002 turbofan engine, it is a big problem. You must carry out a series of transformation on the body to transform the engine from built-in to external model.


    However, the benefits of such transformation are also very obvious. Although after such transformation, the survivability of No. 6 aircraft cannot be improved in essence, and it is only a subsonic non stealth aircraft, its operational radius, operational efficiency and ammunition load will be greatly improved.


    Moreover, after such transformation, this aircraft can not only use your tg-s002 turbofan engine of Tiangong technology, but also have more engines to choose from. Even those turbofan engines with high thrust and large bypass can be installed. In this case, its bomb load can be prompted.


    At the same time, because the engine is turned into a mounted type, the original engine compartment of the aircraft can also be cancelled, so that the internal space of the aircraft will become larger and the fuel and ammunition carried inside will become more. "


    After listening to Qiu Tuan''s words, Wang Bin also nodded. If you want to use tg-s002 engine for unit 6, such transformation is necessary, and the amount of transformation is indeed very large. At the same time, the performance after transformation is also very attractive to Qiu Tuan.


    However, for Wang Bin, he is not interested in transforming unit 6. The most important thing is that the small bypass turbofan engine of Tiangong technology is already under development, and the test run can be completed in a short time.


    Therefore, instead of retrofitting unit 6 so that it can install tg-s002 turbofan engine, it is better to directly install tg-wsx1 turbofan engine, that is, the small bypass ratio turbofan engine being developed.


    The small bypass ratio turbofan engine that Tiangong technology is developing now has the right name, that is, tg-wsx1 engine. TG naturally represents Tiangong technology, WS is the first letter of turbofan Pinyin, and X is also the first letter of small Pinyin. Finally, type 1 is the first model of this engine.


    In this way, not only the amount of reconstruction work is very small, but also the engine compartment and body need to be strengthened, so that it can bear greater bomb load and carry more fuel.


    So he opened his mouth and said to Qiu Tuan: "Qiu Tuan! To tell you the truth, I don''t agree with such a big transformation of aircraft 6. Although after such transformation, the bomb load and operational radius of this aircraft will be greatly improved, anyway, the nature of this aircraft is still different, there are too many changes, and it is just a subsonic non stealth fighter.


    Most importantly, the research and development of small bypass ratio turbofan engine by Tiangong technology has also entered the test run stage. The research and development of small bypass ratio turbofan engine suitable for Fighter 6 will be successful at the beginning of tomorrow at the latest.


    So I think instead of spending so much effort, it''s better to install a small culvert directly at that time, which is more suitable than a turbofan engine, and there''s no need to wait too long. "


    "What? Mr. Wang! Your Tiangong technology has developed a turbofan engine suitable for unit 6, and has entered the test run procedure?" Qiu Tuan was surprised after listening to Wang Bin''s words.


    After all, Tiangong technology has launched new engines one after another in the engine area during this period. Not to mention the electric aviation engine, but only in the turbofan engine, two turbofan engines have been successfully developed, and one turbofan engine with greater thrust has almost completed the test run, and now another turbofan engine has entered the test run stage, For Qiu Tuan, part-time work is like a dream.


    However, he continued to ask Wang Bin, "Mr. Wang, I don''t know the performance of your newly developed small bypass ratio turbofan engine. Can you tell me so that I can have a bottom in my heart?"


    Later, Wang Bin told Qiu Tuan some basic data about the small bypass ratio turbofan engine being tested.


    When Qiu Tuan heard the representative''s introduction, his expression was even more shocked. The maximum thrust of about 30 tons can support the maximum flight speed of 2.5 mach, the maximum flight capacity of 25000 meters, and the consumption of fuel is larger than that of turbofan engines with large bypass ratio, but compared with similar engines For the turbofan engine, especially in cruise, the fuel consumption is very economical.


    Therefore, after listening to Wang Bin''s introduction to this engine, he already knew it in his mind. Although it was, the thrust of this engine was far more than that required by No. 6 engine.


    After all, No. 6 aircraft is only a subsonic medium-sized aircraft. At the same time, the maximum thrust of a single engine of this aircraft is less than 15 tons. Therefore, when Qiu Tuan listened to Wang Bin''s words, he also had a great doubt that the performance of this engine is really excellent. If he goes to No. 6 aircraft, part-time work would be a waste.


    However, as Wang Bin thought, if the engine is installed on the No. 6 aircraft, it can indeed immediately and effectively improve the performance of the aircraft. Not to mention anything else, it can be greatly improved only in terms of speed. It is not impossible to reach a flight speed of twice the speed of sound. Of course, the premise is that the body of No. 6 aircraft can bear it.


    Secondly, if two such engines are installed, the bomb carrying capacity of the aircraft will also be improved qualitatively, at least much more than the transformation scheme originally proposed. After all, the thrust of a single engine of this engine reaches about 30 tons. Therefore, if two such engines are used to improve aircraft 6, the static thrust of this aircraft can reach 60 tons, Therefore, if the No. 6 aircraft only changes its engine without changing its fuel load, it can definitely increase its bomb load by more than 100%, that is, the bomb load of this aircraft can reach at least 40 or 50 tons.


    However, this is obviously impossible. Even if the engine can take off with such a large weight, the aircraft body can''t stand it.


    Therefore, if the engine is to be installed and the maximum bomb load and fuel load are to be achieved, it is also necessary to transform the body of unit 6. In fact, the engineering quantity is relatively large, but such transformation is much better and the engineering quantity is smaller than the transformation scheme discussed earlier, that is, the transformation scheme using tg-s002 engine, Therefore, Qiu Tuan was more inclined to this transformation scheme at this time.
