By the end of the three-year period, Whittle had left China for the United States and had become an ordinary engineer, and the Chinese government had deliberately concealed his presence in later propaganda, so that Whittle had barely left any mark on the history of this time and space, and even had a reputation in history

Hu Weidong's method of "killing people without seeing blood" in letting foreign experts leave their scientific research posts to engage in simple work for a long time has also deterred those foreign experts who come to China, and made them understand that if they cannot guarantee that they will work for China wholeheartedly under any circumstances, they should simply not enter institutions or departments that have a much higher level of secrecy despite their higher funds, so as not to mislead others and themselves

The average age of the Chinese researchers in the institute is less than 25 years old, and they are basically ducks on the shelves after graduating from the bachelor's degree

Although he was only 24 years old in 1941, the young Wu Zhonghua became the chief engineer of the Gas Turbine Research Institute of the Chinese Academy of Sciences, and no one raised any objections, and he became the first person in Chinese history to be the head of a first-class research institute (Note 1) with only a master's degree. Under the leadership of this genius who had a rough life in history, the Gas Turbine Institute had largely eliminated the effects of Whittle's departure in less than three months, and by the end of October 1941. They built the first Shiyan jet engine on the Shijie that could work stably.

After learning the details, Hu Weidong began to congratulate Frank. Whittle's departure because more than a year ago, Wu Zhonghua, who was still working on him, realized that Frank. Whittle's jet engine had major flaws, and it was impossible to build a stable engine with the current level of craftsmanship and materials in China, or even Shijie. Whittle, however, was disdained by his racist (Note 2) and rejected the Chinese disciple, who was only an undergraduate at the time. Instead, he proposed to Hu Weidong to expel Wu Zhonghua from the institute. Fortunately, Hu Weidong was well aware of Wu Zhonghua's genius and achievements in history. Whittle's dissatisfaction was suppressed so that he would not regret it for the rest of his life.

Hu Weidong also realized that there is a highly professional research direction for aero engines. Even if he's a time-traveler. It is not possible to give the right guidance at all times, as it is in those familiar areas. But a capable person like Wu Zhonghua, who has shown outstanding talent both in history and in this time and space, is fully worthy of his entrustment

It is worth mentioning that at that time, Hu Weidong in order to appease Frank. Whittle. Wu Zhonghua was transferred to the gas turbine research group, so as not to delay the development of jet engines because of the argument between the two. However, the research on gas turbines has a lot in common with jet engines, so the transfer did not leave Wu Zhonghua out of his field of expertise, and many of the results of his research are also useful for jet engines.

More importantly, Wu Zhonghua did not give up his insistence, he believed that the reason why Whittle ignored his opinion was because he did not propose a more haode idea, as long as he could find a more haode, he could persuade the teacher to change his course. After more than a year of research, Wu Zhonghua found that perhaps it was better to change the design of jet engines to the centrifugal principle, and after Whittle's departure, Wu Zhonghua, who had gained more power, was able to devote more resources to his own research, and achieved phased success. Whittle was wrong, and Hu Weidong couldn't help but be relieved, "Who said that we can't build haode aero engines in China?" ”

In fact, the reason why China's aero engine has lagged behind the advanced level of Shijie for a long time in history is that the country has not paid enough attention to it for a period of time (but with China's national strength at that time, it is good to be able to ensure the key projects such as two bombs and one satellite in the nature of "sending charcoal in the snow", and there is really not much spare power to invest in secondary projects such as aero engines. In addition, the backwardness of the level of technology and materials is the biggest limiting factor.

And in this time and space, because Hu Weidong brought hundreds of high-temperature and corrosion-resistant modern alloy material formulas and processing techniques in his memory (although these materials were not originally used to make engine components, but because the performance exceeded that of the World War II period too many materials, even if they cameo, the effect is not bad, and they also play a role in enlightening ideas, so that Chinese materials scientists can find more Haode materials on this basis. China has launched a full range of jishu cooperation with Germany, buying and exchanging a large number of materials and processes with Shijie's advanced level, so unless the United States and Britain and other countries steal or research (individual materials are possible, but after all, the age is too different, at least eighty percent of the materials Americans are unlikely to study the formula and process within ten years. The super-era material formulas brought by Hu Weidong, at least for ten years, China will be more advanced than the United States and Britain in the area of high-temperature and corrosion-resistant alloy materials, which is the key to Wu Zhonghua's rapid breakthrough.

Note 1: Hu Weidong divided the major scientific research institutes in China into four grades, from high to low: special grade, first grade, second grade and third grade. Although the two main topics of the Gas Turbine Research Institute (jet engine and gas turbine) are very important, they are not as strategic research directions as rocket and nuclear engineering, so they are only designated as Class I for the time being. However, the money factor is only one aspect, and the excellent work of Wu Zhonghua and others is the key to which the central authorities attach more and more importance to it; after all, jet engines are important, but after all, they are not as vital to the life and death of the country as the two bombs and one satellite, and no matter how much the price is paid, they must produce results as soon as possible; therefore, Hu Weidong, who is in charge of scientific and technological work, will pay more attention to it only when he sees the results and thinks that this research institute is worthy of increasing investment

Note 2: At the beginning, Frank. Whittle accepted Hu Weidong's invitation to come to China, purely because there was no money to continue research in Britain, and at that time, the country was in urgent need of scientific and technological talents, Hu Weidong did not have room to pick and choose, as long as people were willing to work seriously, he could still tolerate a little sulking, but when he neglected his duties because of the war between China and Britain, he inevitably touched Hu Weidong's bottom line.
