Old Qin, chief engineer Lin and others left after visiting Tiangong technology that afternoon.


    However, when they left, they didn''t leave empty handed. They also took away five engines of Wang Bin Tiangong technology, including two 350 ton QY1 rocket engines, one 150 ton liquid methane engine, one 50 ton liquid methane engine and one tg-s002 large bypass ratio turbofan engine.


    Although these engines, other than the 350 ton enterprise type I rocket engine, are still under test and have not met the requirements of design data, this is only the design requirements of Tiangong technology. According to the official standards, whether it is tg-s002 large bypass turbofan engine, Or 150 ton and 50 ton liquid methane engines, their performance has far exceeded.


    After all, according to the official standard, as long as the first repair time of the turbofan engine reaches more than 3000 hours, it is definitely an engine with a long service life. Now, the lowest of the ten tested engines of Tiangong technology''s turbofan engine has exceeded 15000 hours, and the highest has even reached 20000 hours, Although such service life has not reached the design life of more than 25000 hours, it has definitely far exceeded the official standard.


    As for the rocket engine, the same is true. Although it is said that the design standard data of Tiangong technology, the rocket engine must adhere to one or two hours at the maximum operating power. In other words, the standard of Tiangong technology is the same as that of aeroengine, which is calculated in hours.


    However, for official space agencies, the life of rocket engines is calculated in minutes or even seconds. Therefore, according to the design standard, these liquid methane engines must be able to operate continuously at maximum power for two hours before they can meet the design data standard.


    Therefore, the performance of these engines is definitely very advanced for officials.


    However, even so, these engines cannot be used immediately after Qin and others take them back. In other words, the role of these engines is not directly used in official aviation or spacecraft. The most important role of these engines brought back by Qin and others is to carry out performance testing in all aspects.


    ..........


    However, on the night Qin and others returned, Wang Bin received a call from the county official.


    "Mr. Wang! You are not authentic! The superior came to your Tiangong technology for inspection. Although he said he had no direct contact with our county official, he also informed us so that we could be prepared!" when Wang Bin connected the phone of the person in charge of the county official Industrial Zone, the person in charge complained.


    You know, this is a real superior! He is the person in charge of managing the National Aerospace! As long as this can help say a few words, it is definitely a great achievement for the county. After all, Tiangong technology is in the county under his jurisdiction, and the achievements of Tiangong technology are even the achievements of the county.


    "Director Lu, you are really well informed! But you can''t blame me for this. The superior informed us of our Tiangong technology inspection, so we didn''t have time to tell you about the county government.


    However, director Lv is very satisfied with our inspection of Tiangong technology. At the same time, we are also very praised for the various concessions given by the county to Tiangong technology. "Wang Bin said after listening to director Lv''s words.


    "That''s good, but Mr. Wang, if any superior comes to inspect Tiangong technology in the future, please be sure to inform our county government, so that we can be prepared!" director Lu said.


    "OK! Director Lu, we will inform you next time!" Wang Bin nodded.


    "By the way, I have something to tell you. Several leaders of our county will come to your Tiangong technology for condolences tomorrow. I don''t know if there is any problem!" director Lu said.


    "OK! Director Lu!" said Wang Bin.


    .................


    Not to mention that the county leaders went to Tiangong technology, after Qin and others returned, that night, the news of Qin and others inspecting Tiangong technology appeared on the Internet. After all, Qin and others came to Tiangong technology this time, although they were relatively low-key, they did not keep it confidential.


    There is even a detailed report about Qin Lao and others'' inspection in Tiangong technology.


    Therefore, this time, Qin Lao and others visited Tiangong technology and praised Tiangong technology. After it was reported, it caused great repercussions on the Internet.


    "Oh, my God! There is another private aerospace company in China. The most important thing is that this company has successfully developed a 350 ton hydrogen oxygen rocket engine. This is absolutely great good news, which directly proves that we have another strong private aerospace company in the aerospace field, which also marks our great progress in the aerospace field A step forward. "


    "Yes! This is not the most important thing. The most important thing is that according to the relevant reports, the first rocket manufactured by Tiangong technology will be launched on the last day of the air show at the offshore launch platform in the South China Sea, and the rocket will also carry the deep space communication satellite of China National Space Exploration Corporation. It can also be seen from here that the technology of Tiangong technology is unique It is not comparable to ordinary private aerospace companies. Otherwise, this rocket will not carry such an important satellite when it is launched for the first time.


    After all, this is a deep space communication satellite! It is an important part of our country''s construction of deep space communication network! "


    “......”


    In fact, the hot discussion on Tiangong technology on the Internet was limited to some professional Aerospace websites at the beginning, but with the continuation of time, the events were also fermenting, and soon appeared on several major military and major websites in China.


    At the same time, it has long disappeared on the Internet, and relevant reports on other products of Tiangong technology have been turned out again, such as optical glass of Tiangong technology, special bearing steel of Tiangong technology, the first engine of Tiangong technology, etc.


    Even some basic properties of some products have been put on the network. Of course, the basic data of some products are not accurate.


    For example, the real maximum thrust of TG-001 turbojet engine of Tiangong technology has reached more than 16 tons, and even the cruise thrust has reached about 14 tons. However, according to the data on the network, the maximum thrust of this engine is less than 14 tons, while the cruise thrust is only about 11 tons, It is far from the real data of this engine.


    After all, tg001 engine is a military engine, so its data can not be disclosed to the public. In fact, the data on the network is only the data speculated by some people. However, with the current scientific and technological level of Huaxia in this regard, many people still choose to believe these data on the network.
