Chapter 117 It’s Not Always Our Fault Compared with the United States, China has always been weak in the field of aviation engines. The early test flight of the Z-20 was still equipped with the AL-31F engine of Russia. Later, after the domestically produced WS-10 was successfully put into service and mass production, it was gradually replaced by the "Huaxia Heart". However, the level of the WS-10 engine can only be considered world-class, and there is still a big gap compared with the advanced F119 and other top engines of the United States. Considering that the Z-20 still has a lot of room for improvement, a newer engine - the WS-15 has become our urgent need. Now Jiang Hao has also joined this work with his team. This has given Jiang Hao an inexplicable pressure and he has also learned to be cautious. …… This time, the new experiment of "Institute 606" was conducted according to the new plan involving "Air Research 106 Group", so the data generated by the experiment are all new. The current work of the "Air Research Group 106" is to re-analyze and organize these data based on "Jiang Hao's mathematical thinking", so as to change the perspective and re-understand the "WS-15" from the perspective of "Jiang Hao's mathematics". This job is simple to say but difficult to do in reality. It requires all members of the team to abandon their previous inherent way of thinking and think about problems in a new way.
Of course, new problems also arise with new ideas. When the "Space Research Group 106" officially completed the data analysis for the first time, the group immediately fell into doubt when seeing the unreasonable new results: "How could this result happen?" "Yeah, that's unlikely. With such a high total pressure ratio, there won't be a surge problem? Impossible!" "Is there something wrong with our calculation process?" "How could such a result occur?" "Team Leader, what do you think?" After a brief debate, everyone threw this question to team leader Jiang Hao. Jiang Hao frowned, crossed his hands over his chest, and stared at the results deduced on the whiteboard carefully. The entire derivation process is led by Jiang Hao, so there should be no calculation problems. 可问题是，姜浩的很多运算逻辑都是全新的，比方说，原本的一些运行逻辑是“1+1+1+1=4”，而在姜浩这里，他运用的运算逻辑是“2+2=4”或者“1+3=4”。 Although the running results are the same, different calculation logics explain different problems. "1+1+1+1=4" explains the addition of four "1", while this new logic explains a different problem. But shouldn’t such an unreasonable result occur? Although Jiang Hao is not from a professional aviation background and his aviation knowledge is entirely a recent cramming effort, he has also read a lot of aviation textbooks and literature. The current result is too unreasonable! Even Jiang Hao didn't know how to "remedy the situation". Is it that my calculation logic does not match it? My mathematical thinking is not suitable for data analysis in this field? Or is my mathematics simply wrong and useless? Jiang Hao really had a headache. At this moment, he really regretted that he had no knowledge of aircraft engines in his previous life, so that he now had no reference from his previous life. After standing in front of the whiteboard and thinking for a while, Jiang Hao said, "Pull another whiteboard over here and let's do the calculation again." "Whoa whoa whoa~"
After Jiang Hao finished speaking, everyone immediately hurriedly pulled over a blank whiteboard. At this moment, the atmosphere in the teaching and research room was very solemn. This "unreasonable result" was like an extremely gloomy dark cloud, hanging over everyone's hearts, making everyone feel suffocated. Everyone's eyes were focused on the team leader Jiang Hao. They waited nervously, hoping that the team leader would find the error in the new calculation and get a normal new result. "Swish, swish, swish~" It was late at night, and the city that was bustling with traffic during the day had long since fallen asleep. In this quiet teaching and research room, everyone's heart was beating along with the pen of team leader Jiang Hao. Time passed by minute by minute, and Jiang Hao quickly finished writing on a whiteboard. Jiang Hao completed the last calculation very quickly. Because he was confident and wanted to save time, he omitted some steps that could be omitted. But the result obtained last time gave Jiang Hao a heavy blow. For Jiang Hao, this feeling was just like when he was doing the last big question in mathematics for the college entrance examination. He was full of confidence and felt that he would definitely get it right. His calculations were very smooth, but in the end he got a result from physics. This made Jiang Hao feel very disappointed with his "full of confidence" and "definitely got it right". So when he rechecked the calculations again, Jiang Hao not only proceeded very slowly, but also went through each step very carefully and did not dare to skip any. Time passed minute by minute, and everyone present held their breath, thinking and deducing carefully along with the calculations of team leader Jiang Hao. "Ah?! Why is it still the same result?" When Jiang Hao completed the derivation carefully again and saw the same result, a member of the teaching and research department subconsciously said something. "Are we wrong?" Nong Yunliang, the leader of the "1063" team, stared at the whiteboard and thought seriously for a while, then raised a question that no one dared to say out loud. Although "Jiang Hao Mathematics" is a new mathematical logic, everyone present is an elite. They have all studied and received "Jiang Hao Mathematics" seriously, so when Jiang Hao conducts detailed deductions and calculations, they are able to keep up with Jiang Hao's thinking. They were sure that there was nothing wrong with Jiang Hao's deduction, but why did such an unreasonable result appear? The only possibility is that it was wrong from the beginning. This was a speculation that made everyone feel depressed. The already solemn atmosphere in the teaching and research office became even more solemn. In the quiet teaching and research room, no one even dared to take a deep breath. They stared nervously at the young team leader Jiang Hao who was standing in front of the whiteboard and thinking seriously. Seeing the same result after the second calculation, Jiang Hao was also deeply skeptical at first. But when he applied this deduction process to the entire aircraft engine system, Jiang Hao thought for a while, shook his head, and said to everyone: "It may not be our fault." After Jiang Hao said this, the originally depressing atmosphere in the quiet teaching and research office eased a lot. Although this team leader is very young, through the contact over the past few months, everyone is still very convinced of his ability and wisdom. Jiang Hao turned around and looked at everyone, then said, "The reason why this problem occurred here is, on the one hand, because we are taking a new route, and on the other hand, it may be due to the bypass ratio problem." Glancing out the window and seeing that it was already late at night, Jiang Hao said to everyone, "That's all for today. We have been working overtime for a week. Let's take a good rest tonight and continue to work hard tomorrow!" "Tomorrow, we will use the same mathematical thinking and direction to analyze the bypass ratio!" "If the result of the bypass ratio analysis is the same as this one, which is not in line with the norm, then it means we are not wrong!" After Jiang Hao finished speaking, the teaching and research office fell into a whispered discussion, and Jiang Hao sat back at his desk, picked up a new blank draft paper, and began to write and draw calculations. Although Jiang Hao had said that it was time to go home from get off work, no one left the teaching and research office. Everyone returned to their desks and began to work seriously.
