However, when Wang Bin and others re prepared to install the new engine on the test bench, most people in Tiangong technology company a few kilometers away also paid attention to Wang Bin''s situation, because Wang Bin''s research and development of aeroengine by Tiangong technology is no secret to Tiangong technology''s employees at this time.


    After all, various parts of the engine are produced by Tiangong technology. In addition, the sound of engine test is so loud that these employees naturally know that it is the sound of aeroengine.


    Even people who don''t know will inquire about each other at the moment when the engine test sounds. Naturally, they will know what this is.


    Of course, when the sound of engine test just sounded before, all employees of Tiangong technology were very happy. You know, this is an aeroengine! This is really high technology! It''s an industrial crown! And now their Tiangong technology is actually developing aeroengines.


    Now, the research and development has been successful and the test run has begun. This is definitely a very proud thing for all employees of Tiangong technology. After all, many of them have participated in the parts manufacturing of the engine. Even if they have not participated, the engine is developed by their company.


    Therefore, after the sound of engine test started, all employees of Tiangong technology silently prayed that the aeroengine developed by Tiangong technology could succeed this time.


    However, just when everyone was happy to listen to the whistling sound from the engine test run, the sound of the engine suddenly disappeared, which made everyone of Tiangong technology wonder what was the matter, whether the experiment was successful or failed, so many people began to talk about it.


    "How did the sound of the engine disappear all at once? What happened? Did the experiment fail?"


    "Yes! But everything was fine before. I don''t think there will be any problems! I don''t think the experiment will succeed?"


    "I think it may have been successful, especially when the engine sound is very sharp in the last few minutes. I think it should be an afterburner combustion test. You know, it''s great that the afterburner combustion of general aeroengines can last for dozens of seconds, and the aeroengine of Tiangong technology has been a few minutes. I think it must have been successful!"


    .......


    However, while the employees of Tiangong technology talked about it, in the test workshop a few kilometers away, those young technicians finally installed the second engine on the test bench.


    Although this is only the first test run, they naturally prepared standby engines just in case, and not only one standby engine, but also directly manufactured as many as five, that is to say, except for the one tested before, there are still four standby engines in the workshop.


    Soon, with the efforts of those young technicians, the engine was installed on the test bench, and then carefully inspected each part of the equipment until it was determined that all parts were installed in place. All personnel withdrew from the vicinity of the test bench again, re entered the control room and started a new test.


    Although the previous single engine has been tested for many items, due to the replacement of an engine, all the test items must be pushed over and retested.


    So before long, the scream of the aeroengine sounded again in the test workshop, and the workers in the Tiangong technology plant a few kilometers away were finally relieved and listened to the sound of the engine happily.


    In the test shop, Wang Bin and others looked at the engine being tested, but their mood was not as nervous as that of the previous engine test. After all, the previous engine had been tested in an ordinary test, and it was impossible to think of any problems.


    "Lao Dai! After the test run, let the young people take it apart, have a good look at the damage of the engine and record the data. After all, even the previous test run is very important for this engine.


    After all, this is afterburner combustion in case of cooling system failure, which enables us to better understand the operation of this engine, as well as the working condition and working time of the engine in case of similar faults in the future, "Professor poke said to Dai.


    After listening to Professor Zhang''s words, Dai also nodded and replied: "indeed, the previous test data is really very important to us. It really simulates the state of the engine when the cooling system fails!


    So wait a minute, I will personally take charge of this matter to check the internal situation of this engine and record the data! "


    "That''s good!" said the professor!


    After the start of the test run of the new engine, the steps of the previous engine test were very normal and no problems occurred. Of course, this was expected by Wang Bin and others. It was not until they re entered the maximum thrust test, that is, afterburner test, that the face of Professor poke and others became serious again, and Wang Bin''s mood was raised again.


    However, Wang Bin''s worry seemed superfluous, and the condition of the engine far exceeded the expectations of Wang Bin and Professor Cuo. The engine continued for nearly an hour in the afterburner stage before slowly starting to slow down. Of course, this is not a problem with the engine, But the fuel prepared by Professor Zhang and others is not enough to continue the test run.


    After all, although the aeroengine has a strong working efficiency, the fuel consumption of the engine is also very amazing. In such a short time of less than an hour, it has burned dozens of tons of fuel, which is definitely a real money burning.


    You know, this is aviation kerosene! The price of each ton is more than 3000. Even if the situation is special this year, the price is as high as 289. That is to say, Wang Bin''s test run burned hundreds of thousands in less than an hour. If you add the loss of the engine, the kerosene burned by the previous engine and the engine itself.


    The money burned by their Tiangong technology in this test run is definitely more than tens of millions, which makes Wang Bin really feel that aeroengines are really not something that ordinary companies can play.


    If it is an ordinary company, not to mention the research and development of engines, even if it is burned in the test run, it is enough to make them bankrupt.


    As their aviation kerosene ran out, it also meant that the test run had been perfect and successful. The data far exceeded the expectations of Professor Zhang and their staff, and exceeded the drawing design data. In the whole test run workshop, all the young people cheered at once. Everyone jumped and shouted, hugged and hugged, and some threw their hats high.


    Even the professor poked them in the face and finally smiled.
