Chapter 1331 The problem is not big .jpg


    It is similar to the situation estimated by Chang Haonan. After confirming that the X51A aircraft test failed and lost contact, the Boeing, inclusive and Pentagon held a joint investigation team after a press conference that night.


    Of course, after all, it is just an accident within a normal range. In addition, the spring and autumn brushwork is in place, so it will not trigger the accountability mechanism.


    The investigation team is still formed from the project team. It is led by the project leader of Dr. Collinjie of the project. However, it has joined several engineering staff of the National Defense Senior Research and Planning Bureau. As assistants, speed up the progress of work.


    After that, Collinjie divided the entire investigation team into two in accordance with the convention, and each independently collected and analyzed the remote test data, and then analyzed detailed fault trees to ensure that the confirmed abnormal data was accurate.


    Even with all the first -hand information, this process alone took almost a month.


    It should be said that from the perspective of accident analysis, this series of operations under the command of Collinjie are no problem.


    However, the dismissal of the two levels of theory and engineering is not what his senior engineer can save by his personal power.


    When Chang Haonan sorted out the report and handed it to Zheng Liangqun.


    In the Wilmington Test Center on the other end of the earth, the first plenary meeting since the establishment of the joint investigation team has happened.


    Collin Jie was sitting at the long strip conference table, and two laptop computers were placed parallel in front of them.


    It was the analysis results submitted to him by the two faulty tree analysis teams.


    If the two are the same, it can be confirmed as a valid source of danger, and if there are differences, you need to return to the last same link in the tree analysis and repeat the above steps.


    "Everyone, Dr. Shelton, who submitted these two submitted reports, has all seen it with Dr. Sheldon of the National Defense Senior Research and Planning Bureau."


    Only for more than a month from the accident, Collinje''s originally dense hair had already had bald symptoms, and his tone was full of exhaustion when he spoke:


    "In the end, we determined that the accident tree formed by the two teams can be performed in the same identification ..."


    When this sentence is exported, the entire meeting room suddenly reached an extremely subtle atmosphere.


    It can be described as a few happy and happy.


    For most of the heads of the system, including Dr. Collin Jie himself, although the test results itself did not reach expectations, as long as the accident analysis process can be completed normally, and then solving the problem targeted, it is always a good progress.


    But Daniel Jobornsky, who had ghosts in his heart, was extremely nervous in an instant.


    After all, he knew that the test report of the solid rocket aid was processed.


    There is even no need to analyze the accident tree. You only need to find out all the original data and analyze it again, and you can see the greasy cat.


    Almost subconsciously, he turned to look at Melli Herst next to him.


    After traveling to Alaska last Christmas last year, the two have become a grasshopper on a rope.


    However, the latter still looks like usual, and it looks similar to nothing.


    It seemed that the opponent''s panic was discovered, and Helster gave him a peace of mind.


    But this did not calm Joberosky, but became more heartbeat accelerated.


    He passed away slightly, and seemed to want to say something to Heaster.


    But it was interrupted by Collin Jie''s voice:


    "The accident analysis team determined that the aircraft was not successfully accelerated to the expected value."


    "After the engine starts running, the temperature and pressure in the internal segments are observed abnormal. After studying 156 different nodes, the source of the accident pointed to the exhaust port and the aircraft body installation of the pipe port of the engine. The sealing problem of the indoor port ... "


    When the first sentence was over, Jobrenzki almost fainted because of nervousness.


    But immediately he realized that the other party said that "the unsuccessful acceleration to the expected value" refers to the launch of the super -burning stamping engine, not before.


    The following content shows that the accident analysis team has not considered the perspective of the problem with the help of the weapon, but directly aimed at the aircraft body.


    Before he could understand the ins and outs inside, I heard Collinjie continue to say:


    "Although during the wind tunnel test, we know that the super -burning stamping engine and the hypersonic flight will form a strong heat environment, but still underestimate the intensity of this effect to a certain extent. It is indirectly calculated according to the sensor data. After experiencing 140, 140 After the second flight, the ultra -combustion stamping engine body was actually heated about 0.75 inches, which increased the difficulty to seal the interface interface interface interface connected to the engine and the aircraft body ... "


    "The two teams dismantled the engine on the verification machine No. 2 and No. 3. Finally, it was found that the sealing could not withstand such amazing high temperature and deformation, resulting in the engine when the engine was working, and some of the heat contributed by the thrust contribution did not according to the design exhaust port that was not designed according to the design exhaust port. The passage is discharged, but leaks from the rupture of the cracks into several cabins on the rear of the aircraft.


    "On the one hand, the temperature that is constantly rising is sufficient to melt the circuit board and welded of other key equipment for melting the remote test equipment. The situation is consistent ... "


    "..." Jobrenzki was very serious at first, and even memorized a lot of notes.


    But soon, he paid attention to some details other than technology:


    For example, in this analysis conclusion, a series of issues such as wind tunnel research, theoretical calculation, bomb design, engine production, etc. are also mentioned.


    Highlight a rain dew.


    It seems that each link is related to this "partial success".


    As we all know, everyone needs to take responsibility, which is equivalent to that everyone does not have to take responsibility.


    As for why the Rockets they are responsible for the Rockets are not mentioned ...


    It is estimated that it is just because it is not important enough.


    About half an hour later, Collinje finally read the lengthy preliminary analysis conclusion, and set new tasks to the team members who re -combined into one.


    It wasn''t until this time that Jobrenzki, who had a heavy mind, finally stopped panic.


    But he was quickly replaced by doubt and curiosity.


    There is no mistake, one, one, one, one, one, one, one, one 619, one book, one, one, one, one, one, one, a book!


    Therefore, he quickly found Helster:


    "Meli, why ..."


    The latter seemed to have expected that Joberusky would come over, and even before he said the question, he shrugged and answered:


    "It''s not surprising ... After all, the super -burning stamping engine has successfully started, and it has been working for more than two minutes. It should not be found on our heads."


    "Furthermore, as long as you can find the cause of the accident, it is not good for everyone to trace the roots."


    This is almost equivalent to admitting that the entire accident tree analysis process is greasy.


    Joberrenky does not have much engineering experience, but he is also very clear that if you do not follow the roots, the so -called "cause of the accident" is likely to have a problem.


    "So Dr. Collinjie asked ..."


    "Of course not."


    His words were interrupted again by Herst:


    "It is the meaning of the high -level research plan of the National Defense.


    At this moment, Joberosky suddenly realized that although his team was halfway, he participated in the research and development plan halfway, but under the operation of the relationship between the relationship between the relationship, and the master and sister who was good at communication, it seemed to have penetrated the entire project ...


    Until he left the conference building of the test center, he was in a stagnant state.


    I don''t even know how to get out of Hrst.


    It happened at this time, he saw Collin Jie standing at the door.


    "Collinjie Director."


    The ghost made the gods, and he stopped from behind him.


    "Dr. Jabolosky?"


    Collinjie also recognized him.


    After some brief greeting, Jobrenzki asked quickly:


    "Mr. Director, I want to know why the super -burning stamping engine is still started normally without the speed of the planning threshold ... and will this affect the subsequent work?"


    This problem is obviously beyond the expectations of Collinjie.


    After a while for a long time, he replied:


    "In terms of project, there must be a part of the balance. The actual situation and the calculation of the previous calculation are normal, but the influence ..."


    He hesitated for a moment:


    "At least for the current information, the problem should not be big."
