Chapter 102, "On an Innovative Application of Jiang Hao's Mathematics in Aeroengines" Jiang Hao's special training course in Xijing was originally planned to last eight days, but it actually lasted a full ten days, with two extra days. One day was spent on Jiang Hao's unexpected inspiration, and the other day was spent on Jiang Hao's preliminary explanation and discussion of his recent draft. Although this draft was Jiang Hao's inspiration for the "dual system", by extending the "dual system", Jiang Hao improved the entire lecture system. As Jiang Hao's inspiration and new achievements continue to emerge, his lecture notes are constantly adding new content. As a public figure, Jiang Hao hurriedly returned to Yanjing after disappearing for ten days and appeared in the public eye. Yenching University, Office of “Research on Transformation of World Petrochemical Industry under Jiang Hao Curve Analysis”. This is clearly a project office for the "petrochemical industry", but at this moment, the person sitting in this office is an aircraft design expert - Academician Yang Bin, chief designer of the Z-20. In front of Jiang Hao was a confidential report paper: "An Innovative Application of Jiang Hao's Mathematics in Aeroengines." This paper was newly written by Academician Yang Bin after the introduction of the fourth special training class. From the title of the paper, we can already know the main content of the article. Jiang Hao received the paper three days ago and has finished reading it.
After reading this paper, Jiang Hao, on the one hand, admired Academician Yang Bin's rigorous and strong academic ability, but on the other hand, he was also very cautious about this article. After refilling Academician Yang Bin's cup of tea, Jiang Hao said, "Academician Yang, I know nothing about aircraft engines, but I can assure you that there is no problem with my mathematical thinking in your article. As for the rest, the lecture committee will have to make a collective judgment." The "JHSX Lecture Notes Committee" is an editorial committee with Jiang Hao as the chief editor and more than 20 academicians from various fields as members. The main tasks of this committee are to annotate Jiang Hao's mathematical papers and to review the papers submitted by students in the special training class to decide whether these papers are eligible to be included in the "JHSX Lecture Notes". Academician Yang Bin did not care whether his paper could be included in the "JHSX Lecture Notes". All he wanted was for Jiang Hao to say, "There is no problem with my mathematical ideas in your article." After receiving Jiang Hao's reply, Academician Yang Bin nodded happily and said, "That's no problem!" Mathematics will not directly produce new and usable products like physics, biology, materials science and other subjects. What it brings is more of a theory and a way of thinking to solve problems. Jiang Hao didn't understand aircraft engines, but Academician Yang Bin did. With the help of the new mathematical thinking brought by Jiang Hao, when facing problems in his own field, Academician Yang Bin had new solutions and achieved new results. Seeing Academician Yang Bin's happiness, Jiang Hao panicked. He said hastily, "No, no, no, Academician Yang, my mathematics is just a new direction that has not been accepted by the world." "And there's no valid results to prove that my math is feasible!" “My special training classes and handouts only provide a direction for collective discussion.” "Don't be too hasty to apply this new mathematical thinking to aircraft engines!" Jiang Hao was really anxious. This Academician Yang Bin was none other than the chief designer of the Z-20! The Z-20, which has already made its maiden flight, became a legend in one battle. But there are still some problems, but Jiang Hao knows that it only takes time, and those great military workers in the country will be able to push the Z-20 to the highest level! And there is still plenty of time. More importantly, with the transformation and upgrading of the national light industry brought about by Pinduoduo, and the transformation and upgrading of the heavy industry brought about by the petrochemical industry, the domestic industrial base has become more complete, and the improvement of the battle-20 will be smoother. Jiang Hao didn't want to cause trouble because of himself. Facing Jiang Hao's nervousness, Academician Yang Bin smiled and did not continue the topic. Instead, he changed the topic and asked Jiang Hao, "You haven't been to Shencheng for a special training class yet, right?" "No!" Jiang Hao shook his head and said, "My special training class was held in conjunction with an international conference for the petrochemical industry. There was no conference scheduled in Shenyang, so I never went to Shenyang." Upon hearing what Jiang Hao said, Academician Yang Bin nodded. Academician Yang Bin is an expert in aircraft design, not an expert in aero-engines. But even though he is not an expert in aero-engines, he can come up with new ideas in the field of aero-engines based on Jiang Hao's lecture notes. However, there has been no news from the professional 606 Aviation Engine Research Institute in Shenyang. It turns out that they have not participated in the "JHSX" special training class.
Academician Yang Bin felt that he should go to Shenyang. If Jiang Hao's mathematics could be applied to aircraft engines, it might bring major changes to his "Z-20" project. "I have to go to Shencheng first." After drinking the tea in the cup, Academician Yang Bin stood up and left in a hurry. Jiang Hao hurriedly stood up and said worriedly, "Academician Yang, you really need to think it over carefully!" Office of Cheng Shiying, chief designer of WS-606 aviation engines, 15 Institute, Shenyang, Northeast China. Looking at the chief designer of the Z-20 sitting in his office, Cheng Shiying felt a headache. He said, "Academician Yang, why are you here again? I told you that you have to give me some time! The WS-15 still needs to be improved!" Although the Z-20 has completed its maiden flight, it is equipped with the AL-31F engine produced in Russia. The reason for choosing this engine is simple: domestic engines are not yet mature enough to be used in the test flights of the Z-20. The AL-31F aircraft engine was not only the only choice at the time, but the Air Force had also been using this engine for many years and was very familiar with it. The various logistical support systems were also very sound and easy to use. For a new aircraft model that had just been tested, it was safest to use a mature engine. In fact, since its first flight, the entire Z-20 project team has been working hard to complete the localization of the engine, among which the WS-15 is the ultimate target engine. Because, as the chief designer of the WS-15, Cheng Shiying was under a lot of pressure, and this aviation engine involves a wide range of areas and cannot be achieved overnight. Academician Yang Bin came to urge him in person, and he was really under a lot of pressure. Chief Engineer Cheng Shiying said with a hint of helplessness: "Academician Yang, facing this WS-15, I am more anxious than you. I also want to use it to be elected as an academician!" “But there’s really no rush for this!” Looking at Cheng Shiying who looked impatient, Academician Yang Bin smiled, handed over the paper "On an Innovative Application of Jiang Hao's Mathematics in Aeroengines", and said, "No, Chief Engineer Cheng, I'm not here to rush you today, you see." Chief Engineer Cheng Shiying took the paper handed over by Academician Yang Bin, took a look at the title, and frowned unhappily - he really didn't like others interfering in his project. "Jiang Hao Mathematics?" Seeing an unfamiliar name, Chief Engineer Cheng Shiying asked, "Who is Jiang Hao?" Without reading the paper, Chief Engineer Cheng Shiying said impatiently: "Academician Yang, this matter really cannot be rushed. All experiments must be carried out step by step. Reliability is the biggest requirement! We have time!" Academician Yang Bin smiled patiently and said, "Please take a look at this paper first. I wrote it!" (End of this chapter)
