New Year's Day in 1931 came in a hurry, and when people had not yet come out of the festive atmosphere of the Gregorian New Year that had emerged in recent years, Song Zhewu raised his somewhat tired legs and walked out of the newly renovated Northern Frontier Governor's Office, which was the former military governor's office in Yan Xishan.

During this time, Song Zhewu was so busy that his feet barely touched the ground.

In addition to inspecting the training and defense affairs of the various units, he also had to inspect the resettlement of the disaster victims, the implementation of various administrative affairs in the Taiyuan Administration, Suiyuan, and Nanmeng, the establishment of new schools, and the construction of new factories.

In a word, time is too tight.

In Song Zhewu's feelings, the pace of time was like a roaring cannon, and it was constantly approaching him without hesitation, with a huge threat and thick blood.

Although he was skeptical that he could turn the wheel of history on his own, he had to do so, even if it was to change the wheel of history only slightly, or to slow it down. It can make the Chinese nation shed less blood, the 40,000,000 comrades suffer less, and the country will become stronger and prosperous sooner, and he will do it without hesitation, no matter how difficult it is.

It's just that "9.18" is the time node that makes him anxious, and it is impossible for him to tell anyone, he doesn't want to be regarded as a god, and he doesn't want to cause people to misunderstand.

He had just returned from Baotou Jing Yuexiu last night, and he had not yet recovered from the fatigue of the journey, but early this morning, he and Xiao Guodong had to go to the Fourth Route Army Research Institute on the shore of Jinyang Lake to review and guide the revised five-year plans of various scientific research institutes.

Song Zhewu must personally do the work of reviewing and guiding the revised five-year plans of various scientific research institutes, because only he knows the original historical trajectory best, only he feels the most obvious sense of urgency of time, and only he knows the most clearly and best understands the correct development direction of contemporary science and technology.

Originally, when these research institutes of the Fourth Route Army were located in Laiyuan, they already had a five-year scientific research plan. However, at that time, Song Zhewu had not yet seized Shanxi, and it was impossible for Song Zhewu to reveal his top-secret plan to seize Shanxi to these experts at that time.

Therefore, the five-year plans of various disciplines at that time were designed according to the situation in Laiyuan.

At that time, none of these experts could have imagined that in just one year, Song Zhewu and his Fourth Route Army would undergo tremendous changes in all aspects that might affect the scientific research process, such as manpower, financial resources, equipment, facilities, industrial production capacity, and natural resources under their control.

For example, at least including Ba Yuzao, Guo Wenyuan, Wang Lianzhang, Li Minghua, Zheng Dazhang and others, no one could have imagined at that time that the research institute of dozens of people at the beginning has now soared to hundreds of scientific research personnel who have studied abroad, and the scientific research strength of many disciplines has become the strongest in China, and the responsible people of various scientific research institutes are no longer satisfied with the plans formulated before.

Therefore, before the end of last year, the five-year plans of all research institutes were revised and enriched.

Enhancing scientific and technological strength and speeding up the establishment of a strong national defense industrial system are the most urgent tasks for Song Zhewu at present.

However, Song Zhewu did not get carried away because of many favorable factors, and he was not carried away by the arrival of many talents, and still maintained a very clear mind.

He is well aware that although he has the guidance and guidance of a traverser, the formation of a strong scientific research force and the production capacity of the national defense industry must be achieved in a down-to-earth manner and step by step.

Of course, Song Zhewu will never develop his scientific research strength and science and technology step by step and in accordance with the rules, and it would be a fool not to make good use of the great advantages of the scientific knowledge he had mastered in his previous life and the correct development direction of various disciplines that he knew.

In developing his scientific research strength and industrial construction, Song Zhewu adopted the policy of accumulating strength, cultivating talents, correctly advancing, guiding key points, and running in small steps.

At present, although his scientific research strength is still very weak compared with Western countries, it still has a certain scale, and the best way to speed up the scientific research level of his scientific research personnel and improve the speed of training qualified personnel is to take a number of key projects as the goal, so that his scientific research strength will continue to grow in the course of research and development, and it may even be possible to achieve a small leap in the development of scientific research ability.

This approach was very successful in Song Zhewu's memory in his previous life.

For example, the moon landing program launched by the United States in the 50s and 60s and the research on the "Star Wars Program" carried out in the 80s have greatly promoted the great development of the US scientific and technological level, and the US technological level has always lagged behind all countries in the world.

Song Zhewu wants to accelerate the development of his scientific research strength by developing a number of key and cutting-edge projects that he urgently needs.

Although quantitative change will eventually lead to qualitative change, a certain degree and scope of qualitative change will in turn lead to rapid growth of quantitative change. Song Zhewu believes that through such a scientific research project, his scientific research team will grow rapidly.

The most correct development direction and the most advanced scientific research projects of various disciplines, only Song Zhewu is the most clear, and these high-end scientific research projects must be inspired and issued by Song Zhewu. If these experts and scholars are to gradually explore by themselves, it will take a lot of time, and it will definitely be a waste of Song Zhewu's experience.

Ba Yuzao, Wang Zhu, Wang Xiaofeng, Zeng Yijing, and others are very energetic, and the Aviation Research Institute, which is composed of the engineering and technical personnel they brought from Mawei as the backbone, has already carried out the research and development of fighters, bombers, attack planes, reconnaissance planes, and transport planes at the same time as planned.

Song Zhewu believes that although Ba Yuzao and others are enthusiastic, they have divided their forces a little too much, which is not conducive to making breakthroughs in key areas and coming up with high-level planes as soon as possible.

Although the research and development of new reconnaissance planes and attack planes is progressing rapidly, the development of several other types of aircraft is not very optimistic because of the lack of strength.

After Song Zhewu consulted with Ba Yuzao, Wang Zhu, Wang Xiaofeng, Zeng Yijing and others, these people also realized that they were in a bit of a hurry and did not fully consider the actual capabilities of the Aviation Research Institute. In the end, it was decided to develop fighters, attack planes, and reconnaissance planes first, and after the three types of aircraft were successfully developed, they would then carry out the research and development of transport planes, bombers, and other types of planes that were more difficult.

Song Zhewu's requirements for the development of three types of aircraft: fighters, attack planes, and reconnaissance planes: high, fast, smart, far-reaching, and strong.

Specifically, they must not only fly high, fast and far, but also be more agile and stronger, and this "five-character mantra" is enough to serve as a guiding principle for the development of aircraft in the next 50 years.

In addition to the five-character mantra of high, fast, smart, far, and strong, Song Zhewu also demanded that all aircraft must achieve an all-metal structure.

For Song Zhewu's "five-character mantra", Ba Yuzao and others not only have no objections, but they also very much agree with Song Zhewu's requirements for the aircraft to achieve all-metal standards, they are the world's top experts, very clear that these five words and all-metal structure aircraft, is definitely the right direction of contemporary aircraft development, Song Zhewu's keen sense of the direction of aircraft development are very admired.

However, for the all-metal structure aircraft, they feel that it is temporarily difficult for two reasons: first, the all-metal structure will inevitably lead to an increase in the empty weight of the aircraft, and in order to realize Song Zhewu's "five-character mantra", it is necessary to have an engine with greater thrust; Second, the metal used in aviation is not an ordinary metal material, it must be as strong as possible, but also relatively light in weight. In other words, an all-metal structure aircraft needs a new metal alloy with higher strength but relatively lighter weight.

Now, the Institute of Aeronautics has just been able to design a single-row air-cooled radial engine with a maximum power of 300 kW and a power-to-weight ratio of less than 1 kW/dan. Now the world's most advanced air-cooled radial engine, the maximum power has exceeded 400kw, and the power-to-weight ratio has exceeded 1kw/dan.

For example, the Wright Company and the Pu Company? Hui Company has successively developed single-row 'Whirlwind' and 'Hurricane' as well as 'Wasp' and 'Hornet' engines.

Although Zeng Yijing is very confident in designing the most advanced aero engine, he also believes that it will take at least a year for the Fourth Route Army Aviation Research Institute to design such an engine, and this is because of the help of the technical data that Wang Dong brought back to him.

If the plane wants to fly high and fast, a high-thrust aero engine is indispensable, and Song Zhewu has long been prepared for this.

Song Zhewu believed that with Zeng Yijing's ability, it was certain that he would be able to develop the most advanced single-exhaust cooled radial engine, and even he believed that Zeng Yijing and his researchers would eventually be able to keep up with the pace of the world's aero engine development.

However, Song Zhewu believed that this was far from enough, and with his limited resources, he only came up with an advanced engine of the same era, and although he was not inferior to the Soviet Union and the Soviet Union in terms of the technical level of the aircraft, he was far from catching up with the other side in terms of the number of aircraft. And the disadvantage of quantity, at least in a short period of time, he can't do it anyway, he must beat quantity with quality.

Therefore, Song Zhewu didn't want Zeng Yijing to follow behind others step by step, so that he would always fall behind others, and he had to be appropriately ahead of others.

It is obviously unrealistic for Zeng Yijing's engine research institute, which is still relatively weak in scientific research strength, to develop a turbojet engine that appeared more than ten years later, after all, Zeng Yijing and his team still need to accumulate technology. The development of the twin exhaust cooled radial engine, which was successfully developed before and after World War II, is more suitable for the ability of Zeng Yijing Engine Research Institute.

The twin exhaust cold star aero engine is no stranger to Song Zhewu, he was a military fan in his previous life, but he has studied it carefully, although Song Zhewu is not very clear about the specific principle, but he still remembers the structural layout very clearly.

In order to hide his otherness, Song Zhewu sketched a sketch for Zeng Yijing in the conference room of the Aviation Research Institute in the form of discussion.

Deep Blue apologizes to all book friends! Recently, my family has been grabbing the computer with Deep Blue, and my writing has been delayed! But there is no way, and the family's affairs cannot be delayed, and in two months, it will be good to buy another one for Deep Blue. However, lately Navy will definitely try to try not to release pigeons.
