As the commissioning work continues one by one, it will soon reach the full power working state. At the same time, the maximum power commissioning will last for half an hour as the first time.


    As time goes on, it will soon be half an hour. At this time, a slight joy has appeared in the eyes of Wang Bin, Professor poke and others. After all, the whole process of the test run is very smooth, whether it is the test bench or the engine itself.


    Soon, half an hour''s test run passed, and Professor Zhang finally gave the order to stop the test run.


    When the controller heard the command from Professor poke, he naturally pressed the stop button immediately according to the command. After the controller pressed the stop button, the sound naturally changed and the speed began to slow down slowly.


    "Mr. Wang, Congratulations, congratulations on your successful test drive!" when the engine speed began to slow down and finally stopped, old Xiong smiled at Wang Bin, Professor Zhang and others.


    And the chief engineer Lin on one side, after Xiong Lao finished, also opened his mouth to bless Wang Bin and them.


    Of course, although the test run has been a complete success, the test run of the engine on the test bench next to him has not yet started. Therefore, although Professor Zhang is very happy about the success of the test run, he did not go out of the control room, but asked the controller to start the engine on test bench 2 and start a 24-hour uninterrupted test run, At the same time, the staff were asked to unload the engine on the No. 1 test bench and send it to the assembly workshop.


    At the same time, he also ordered the staff to reinstall an engine on the No. 1 test bench and conduct durability test together. However, unlike the No. 2 test bench, the engine on the test bench will be tested continuously for 48 hours of maximum power.


    Of course, in such a situation, only those bosses who are rich and willful like Wang Bin''s Tiangong technology will do so. If ordinary enterprises or official units develop engines, they will not do so. Their test run will only be carried out step by step.


    One test run, two test runs, and then three test runs, followed by durability tests such as 12 hour and 48 hour test runs.


    Of course, when we arrived here, the inspection of Xiong Lao and chief engineer Lin and others was almost the same. Therefore, after the second test run, Wang Bin took Professor Cha and his party out of the test shop. Professor Cha and others naturally could not follow Wang Bin and them because they wanted to continue the durability test run and the disassembly of the engine.


    After Xiong Lao and others walked out of the test workshop, they did not continue to investigate other projects of Wang Bin''s Tiangong technology, but directly came to the parking lot. After praising Wang Bin''s efforts and encouraging Wang Bin and their Tiangong technology to make persistent efforts and create brilliance, they got on the car with chief Engineer Lin and others and went back.


    On the bus, Mr. Xiong and Mr. Lin were sitting in the back row. After they left the aerospace engine laboratory of Tiangong technology, they talked. Naturally, the content of their chat was about Wang Bin''s Tiangong technology.


    Lin Zonggong Road "Mr. Xiong, the old stamp of this day''s industrial technology has really given us a great surprise! The maximum thrust of more than 13 tons, the cruise thrust of more than 10 tons, and the most important thing is that this engine is only the primary prototype at this time. If slightly improved, the cruise thrust of this engine can reach at least 12 tons in the future, which is definitely a great success Just! "


    "Yes! It''s not easy for Tiangong technology to develop such a powerful engine, which is really very important for our country. Unfortunately, Tiangong technology is only a private enterprise, not an official enterprise." Xiong said with some regret.


    "Mr. Xiong, I think it is precisely because Tiangong technology is a private enterprise that is more valuable, so we should pay more attention to it and focus on support. After all, you don''t know the situation of other private enterprises in China." chief engineer Lin said.


    ......


    On the side of Tiangong technology, with the departure of Xiong and others, Wang Bin was also relieved, thinking that the inspection was finally passed.


    After all, the attitude of old Xiong and others has a direct impact on whether Wang Bin''s engine can obtain airworthiness certificate and a series of procedures in the future!


    Meanwhile, with the departure of Xiong Lao and others, Wang Bin also returned to the mechanical R & D workshop of Tiangong technology and continued to develop the production line of superconducting batteries with Yu Pingping and others.


    When the 48 hour maximum power test run of the engine in the aerospace engine laboratory was completed, Wang Bin and his team finally produced the first production line of superconducting batteries.


    Of course, compared with the superconducting battery production line manufactured by himself and Yu Pingping, Wang Bin is more concerned about the completion of the 48 hour maximum power uninterrupted test run of the engine.


    Although there were no problems with the two engines on the two test stands during the 24-hour and 48 hour maximum power test run, and the working state of the engines was still normal, Wang Bin and Professor Cha were very cautious.


    After the 48 hour uninterrupted test run, Wang Bin even had no time to test the superconducting battery production line. He immediately came to the aerospace laboratory and asked the staff to disassemble the two engines and check the internal conditions. Only after confirming that all the internal parts were normal, Wang Bin and Professor Zhang were relieved.


    With the completion of the internal inspection of the engine and the confirmation that everything was normal, Wang Bin and Professor Zhang became happy. After all, the 48 hour maximum power endurance test run is definitely a milestone for an engine.


    At the same time, with the success of 48 hour uninterrupted test run, it is natural to have a longer durability test run, that is, 72 hour test run.


    "Mr. Wang! Congratulations on the successful completion of the 48 hour endurance test run of the aeroengine of Tiangong technology!" on the day after Wang Bin and Tiangong technology completed the 48 hour endurance test run, Wang Bin received a blessing call from chief engineer Lin of 969 group.


    For chief engineer Lin, he was not surprised to know that Wang Bin and their Tiangong technology had completed the 48 hour durability test run. After all, the current era is not the previous era.


    After Wang Bin talked with chief engineer Lin for a while, chief engineer Lin said to Wang Bin on the phone: "Mr. Wang! I have a document that has been sent to your confidential email of Tiangong technology. Have a look!"


    "What?" Wang Bin asked curiously after listening to chief engineer Lin.


    "Mr. Wang! What I sent you is definitely a good thing. Take a look first. After reading it, I''ll talk to you carefully!" chief engineer Lin said on the phone.
