"Lao Lin, I think you misunderstood. Although I also participated in the manufacturing of this engine, I didn''t design this engine. I just made some modifications to some shortcomings of this engine!" Professor Dai said.


    The drawings provided by Wang Bin are not their own, or even the drawings developed by Huaxia, but the drawings secretly developed by a country in World War II.


    Therefore, the fewer people know about this matter, the better. Therefore, Professor Zhang will not tell chief engineer Lin and old Xiong about this matter, so he can only deny that he designed this aircraft engine.


    However, chief engineer Lin and others simply don''t believe what Professor Cha said. After all, according to the observation of chief engineer Lin and others, in the whole aerospace engine laboratory of Tiangong technology, although there are other people besides Professor Cha and his team, it is obvious that these people are fresh graduates who have just come out of the school, all in their early twenties, If it is something less complicated, it may be developed with the ability of these young people.


    However, this is an aeroengine, one of the most complex scientific and technological structures and the highest scientific and technological content industrial products known to human civilization. It is the Pearl on the industrial crown, which can not be developed by just a few young people.


    In the opinion of chief engineer Lin and others, only Professor Zhang and his team have this ability in this aerospace laboratory.


    "OK! I see!" after listening to Professor Poke''s words, chief engineer Lin and others did not argue with him. After all, in their view, Professor poke was just covering up himself, so they replied with an expression we understand.


    After listening to chief engineer Lin''s words and seeing their expressions, Professor poked no more, because he knew that if he didn''t take out the original picture, chief engineer Lin and old Xiong wouldn''t believe it no matter how he explained it.


    Then, chief engineer Lin and others went to Professor Cha and chatted quietly with Professor Cha and others. After all, the engine is still installed on the test bench with the efforts of those young people. If inspection is added, it will take at least dozens of minutes.


    In the chat between Professor Zhang and Xiong, another half an hour passed quickly. At this time, the engine had been installed on the test bench by those young people and the inspection was completed.


    "All right, Professor Zhang! Mr. Xiong, chief engineer Lin and you, now the two engines have been installed, and other preparations have been almost ready. The test run will begin soon. Please follow me to the control room!" when the engine is installed on the test bench and the inspection is completed, Wang Bin said to Professor Zhang and others.


    After listening to Wang Bin''s words, Xiong and others nodded and followed Wang Bin into the control room. Although the number of Xiong and others is not large, Wang Bin''s control room in the workshop is not small. Even if all the employees in the workshop enter the control room, plus Xiong and others, they can easily accommodate.


    "Prepare for the test run in 30 seconds!" Professor poke shouted when everyone entered the control room!


    The controller, after hearing the wrong professor''s order, immediately replied loudly: "yes! Test run preparation, 30, 29,..."


    Although the engine has been tested once before, and it is still a very successful test run. At the same time, the previous test run also proves that the aircraft engine is still good.


    However, the success of the first test run does not mean that the engine has reached a perfect level. After all, the designer of the engine is only a country in World War II.


    Although at that time, perhaps for this engine, their country has concentrated the capacity of the whole country to design this engine.


    However, in any case, there is a gap between the era and the current era in science and technology, so there is a big gap between many design concepts and material cognition.


    Take the afterburner system of the engine for example. According to the meaning of Professor Zhang and others, afterburner combustion of one level is enough and does not need to be divided into multiple levels. However, after many demonstrations and considering the subsequent improvement of the engine in the future, the multi-level afterburner has been retained.


    In addition, after the first test run, Professor poke and others also adjusted many details of the engine. At the same time, Professor poke and others redesigned some internal parts.


    After all, there is a big gap between the material technology during World War II and the current era. Many parts that had to be used were very thick. If they were put into the present, they would not need to be so at all. Better materials can be used to manufacture parts and optimize their parts.


    "10, 9, 8..... 3, 2, 1, 0" with the countdown to zero, the controller of the console immediately pressed the start button, and the motor on the test bench immediately turned up with the engine on the test bench.


    Of course, this start-up only started one test bench, not two.


    Because the engine on another test bench is not within the scope of this test, but will wait until the engine on this test bench is completed. If there is no problem, then the engine on that test bench will carry out the next scientific test, that is, the first endurance test, that is, 24-hour uninterrupted test.


    As the test run began, the whole control room became quiet, and everyone focused on the starting engine on the test bench.


    Driven by the test bench, the engine grew faster and faster, and soon reached the minimum speed required by the test process. After three minutes, all data were reported to Professor Zhang. Everything was very normal as expected by Professor Zhang and others.


    "Inject fuel! Ignite!" seeing that everything was normal, Professor poke immediately gave the order to ignite.


    After hearing the command, the controller immediately pressed the fuel injection button, and then pressed the ignition button.


    Just after the controller pressed the ignition button, the engine gradually screamed. Obviously, the ignition of the engine was very successful.


    And as the controller gradually increased the injection of fuel, the sound of the engine gradually increased, and a trace of flame began to appear behind the engine.


    "The engine is in idle state, everything is normal!" soon, the engine speed reached the idle state, and there was no problem. There was no change in the faces of Wang Bin and Professor poke. After all, this was the second test run.


    But the faces of Xiong and others were different. At this time, their faces were obviously shocked. They didn''t expect that the test run of Tiangong technology would be so clean. At the same time, they also didn''t expect that this engine would be so excellent.


    You know, Tiangong technology is a pure private enterprise! You know, when the country just started to develop jet engines, the hardships were beyond the imagination of ordinary people.


    As the test run continued, all items of the test run were carried out step by step, and soon the engine entered the cruise test state.
