After meeting and discussion, the superior departments finally prefer to use the engine of Tiangong technology. This is because the performance, reliability and safety of the engine previously produced and sold to the military by Tiangong technology have proved that the engine produced by Tiangong technology is absolutely an excellent engine.


    Whether in terms of the basic performance of the engine or the safety and reliability of the engine, it exceeds the engines of motor companies and northern Arctic countries.


    In addition, the most important thing is that Tiangong technology is a domestic enterprise. Once there is a problem with the engine, Tiangong technology can solve it immediately. Once the foreign engine is selected, it is not so easy to solve it.


    So, half a month after the accident, Qiu found Wang Bin again.


    "Mr. Wang! The investigation results of the same batch of engines in the previous accident engine have been published. According to the investigation results, there are more or less problems with the bearings of more than 100 wholesale engines. The most important thing is that there are problems in not one bearing in an engine, but in all States of the engine, so according to our military professionals According to the analysis, it is not feasible to replace all the bearings in the engine, because in this engine, many bearings are actually connected with the engine, and the most important manufacturer will certainly not allow us to do so, that is, these engines must go back to the factory.


    However, these engines have been installed on the aircraft, and it takes a lot of time to disassemble them. Of course, the most important thing is that the superior has not trusted the engine manufacturer.


    I don''t know Mr. Wang! Does your Tiangong technology have an engine suitable for our main station aircraft? If so, the superior decides to use your Tiangong technology engine, even if the engine still has some defects, but it is not serious, such as those with less thrust.


    At the same time, it was decided at the superior meeting that if you Tiangong technology can solve this problem perfectly, then in the future, major domestic military aircraft manufacturers and aircraft will give priority to your Tiangong technology engine. "After finding Wang Bin, Qiu Shidang immediately finished all what he wanted to say at one time.


    After listening to this, Wang Bin was immediately excited. For the engine of this main fighter, Wang Bin and Tiangong technology naturally have suitable engines. Let alone the tg-wsx3 engine under development, it has almost reached the stage of small-scale mass production. If the superior is willing, they will use the tg-001tg-002 turbofan engine of Tiangong Technology, It can also be installed on this aircraft.


    So Wang Bin said, "Qiu Shi, we naturally have, and there is not only one engine suitable for the 16th main fighter. We have three engines suitable for the 16th fighter.


    The three engines are TG-001 turbojet engine, tg-002 turbojet engine and tg-wsx2 turbofan engine with small bypass ratio.


    Among these three engines, each has its own advantages and disadvantages. Among them, TG-001 and tg-002 engines have disadvantages. Because these two engines are turbojet engines, they have high fuel consumption and high requirements for fuselage strength when flying at low altitude. However, these two engines have excellent high-altitude performance. Aircraft No. 16 is equipped with In the case of two engines, especially tg-002 engine, the aircraft can definitely achieve more than double three standards.


    After all, when we used the seventh master to test the TG-001 turbojet engine on the spot, we could reach the double three standard. Although the diameter of the tg-002 engine is similar to that of the TG-001, the thrust of the tg-002 is two tons larger than that of the 001. Therefore, it is definitely not a fool''s dream to make it reach the double three standard or above after it is used on fighter 16.


    As for the tg-wsx2 engine, it is a small bypass ratio turbofan engine. It was originally developed for our new fighter. Its performance, I think you know, its advantage is that it surpasses the turbojet engine in terms of endurance when the speed is less than Mach 2 and the altitude is less than 20000 meters... "


    With Wang Bin''s introduction, Qiu Shi''s face obviously appeared a smile. Although according to Wang Bin''s introduction, fighter 16, whether preparing to use TG-001 or tg-wsx2 engine, needs to make some transformation to the engine compartment of the aircraft. If you want to use tg-002 turbojet engine, you need to improve the strength of the body, The fuselage skin has been strengthened to some extent, but there is no doubt that the engine problem that bothered them has been completely solved. In the future, the number of aircraft they manufacture will no longer lead to insufficient production capacity due to engine problems.


    So immediately, Qiu Shi reported the situation in front of Wang Bin.


    "Mr. Wang, according to the instructions of our superiors, we are ready to buy 20 TG-001 turbojet engines, 30 tg-wsx2 engines and 10 tg-002 turbojet engines from your Tiangong technology. In addition, the engines to be replaced for the 16 fighters in our base will also be completed by your Tiangong technology.


    In addition, in a few days, manufacturers related to fighter 16 will contact you to order this engine. I have no way to tell you the specific quantity, but according to the instructions of the superior department, the order quantity here will reach more than 300! " After hanging up, Qiu Shi immediately said to Wang Bin.


    After listening to Qiu Shi''s words, Wang Bin immediately smiled. After all, Qiu Shi brought a lot of orders this time. The number of engines of No. 16 fighter manufacturer and the total number of aircraft to change engines all add up to at least 350.


    If calculated according to the price of one thousand two thousand engines, the amount of this order is at least more than 7 billion yuan.


    For this huge order, Wang Bin naturally won''t give up, so he immediately nodded and said to Qiu Shi, "good Qiu Shi."


    Later, after Wang Bin and Qiu Shi talked for a while, Qiu Shi went back to the base, and the next day, the three No. 16 main fighters that needed to change their engines were already in the hangar weight of Tiangong technology, including the plane that had been in an accident before.


    After all, there is no damage to the aircraft except that one engine is completely unusable, so as long as the engine is replaced, the aircraft can still be used.


    At the same time, according to the conversation between Wang Bin and Qiu Shi yesterday, the engines to be installed for the three fighters are also different. They are respectively installed with TG-001 turbojet engine, tg-002 turbojet engine and tg-wsx2 turbofan engine.


    Wang Bin naturally would not object to such an allocation. At the same time, he also knew that the military must want to see which engine this aircraft should use.


    In fact, Wang Bin is not worth it at this time. Because Tiangong technology has three engines, the superior departments are also quite contradictory. Some think that turbojet engines should be installed. In this way, this aircraft can immediately change into a high-altitude, high-speed and multi-purpose fighter, but others think that turbofan engines should be installed. In this way, this aircraft should be installed at low speed, It can give better play to the performance of the fighter itself.
