Even in the stage of the Great Depression of the world economy, the empire did not reduce its scientific research expenditure on military equipment, and the scale of investment in research and development of submarines, carrier-based aircraft, transport aircraft, bombers, tanks, self-propelled artillery, machine guns, and chemical weapons remained the same.

After the Spring Festival holiday, Song Biao, accompanied by Mrs. Qiao, went to Taiyuan to inspect the development of a new tank.

Judging from the characteristics of its geographical location, Northeast China is obviously not suitable for China's only military industrial production base, or even the only heavy industry and high-tech industrial base.

China now has five large industrial regions, namely the Northeast, Jiangnan, North China, Huguang, Shandong, and Henan, and the industrial economic zone in North China includes Shanxi Province, and in the past ten years, the scale of heavy industry in North China has gradually reached the same level as the Northeast, and Shanxi is also the center of gravity of industrial production, second only to the Northeast, China's missile engineering and military materials research center are also in Shanxi.

Although the likelihood of the Northeast being captured is low, in the long run, it is also essential for the empire to have two or three large-scale military-industrial production bases.

In April 1931, Song Biao arrived at Taiyuan Airport by plane and immediately went to the China Academy of Armored Engineering in the suburbs.

At present, the empire has five major scientific research institutions, namely the Central Academy of Sciences, the Central Academy of Engineering, the Central Research Institute of Defense Industry, the Far Eastern Academy of Sciences, and the Far Eastern Industrial Research Institute.

Among the five major scientific research institutions, the Central Research Institute of Defense Industry is the only institution directly responsible for the research of national defense military science and technology, and most of the researchers are from the other four institutes, and the research projects of submarines, carrier-based aircraft, transport aircraft, bombers, tanks, and self-propelled artillery are all led by this institution, and other research institutions and universities and enterprises share the research work of sub-projects, including the research of turbojet engines and the pre-research of turbofan engines.

The only exception is that nuclear weapons and nuclear industry research are separately included in the Central Institute of Nuclear Physics, and this research institute is secretly set up in Hanzhong, and is directly under the responsibility of the Central Secrecy Bureau, which is directly under the inner court.

During the Cold War, the Soviet Union's scientific and technological and economic foundations were much worse than those of the United States, and it relied on this large-scale scientific research system to maintain competition with the United States.

In 1931, the empire has begun to develop the first generation of turbojet fighters, and the locations are in Taiyuan and Yinchuan, taking advantage of the empty and uninhabited conditions of the Tengger Desert to carry out large-scale test flight experiments here, as supporting projects, Taiyuan and Yinchuan have built large-scale hollow bases, The largest hollow bases in the empire were located in Yanjing, Changping County, Shenyang and Nanchang.

Turbojet fighter is the focus of development, conventional propeller fighters also need to be studied, the focus of both aircraft is on the engine, the development of reciprocating internal combustion engine is still very important, aviation reciprocating engine is to a large extent consistent with the engine of automobiles and tanks, but the latter can be designed with more cylinders, and the former can only be limited to four cylinders.

The turbojet engine of the empire was started in 1925, and there have been experimental models in the past two years, but these models are still unstable, two centrifugal types, one axial flow type, axial flow type This is still stopped at the stage of the laboratory, the research report of the Chinese Academy of Sciences is that it is difficult to succeed in ten years, and the required materials are too high in terms of temperature resistance.

Theoretically speaking, it must be the axial flow type, the empire is different from the United Kingdom, the empire took the axial flow design at the beginning, and it turned out that it could not be manufactured, so it chose the same centrifugal type as the British.

In this year, China was slightly ahead of the United Kingdom, because China was directly developed by the central government, with sufficient funds, and the samples had been successful, while the United Kingdom was an enterprise and was still in the theoretical stage.

The person in charge of the National Defense Industry Research Institute is General Chen Qicai, who has also been flying from east to west in the past two years, often going to Shanxi, and has the best understanding of the situation here.

The empire has only 15 generals so far, all of which are related to the Liberation Revolution, the Sino-Chinese Xinhai War, the First World War, and the Sino-Soviet War.

After Song Biao arrived in Taiyuan, he gave priority to inspecting the MBT30 tanks of the Central Armored Engineering Research Institute, the headquarters of the Central Armored Engineering Research Institute is in Yanjing, Yanjing is indeed the main location of China's scientific research institutions, and the Central Armored Engineering Research Institute has four branches, which are located in Shenyang, Taiyuan, Wuhan and Nanjing, which not only cooperate, but also compete, mainly in cooperation with local military industry, metallurgical and other enterprises.

In general, the Central Military Department focuses on Taiyuan, and the Taiyuan Branch has the fastest development speed, and the MBT series tanks have been developed in Taiyuan.

This branch of Taiyuan is not in Taiyuan City, but in Jin County, which is the former Yuci County, because Jin County is the center of Taiyuan heavy industry, and the reserves of coal, aluminum, chromite and ilmenite are very high, and the Taiyuan Aircraft Factory is also located here.

Song Biao didn't even go to Taiyuan Mansion, he took a plane directly to the Jinxian Military Airport and then to the Taiyuan Armored Engineering Research Institute, the empire's aviation industry developed rapidly, and the number of passenger planes in the country has exceeded 1,000, which is mainly supported by the Air Force and the Ministry of Cabinet Communications.

Especially in the past two years, Song Biao went to other places to inspect mainly by plane, he was used to it, Qiao Guifei was another matter, when he got off the plane, his face was still pale, it happened that these military units were special secret institutions, and she could not be allowed to go, so Song Biao arranged for Qiao Guifei to go to the Wandefeng Hotel in Jinxian County to rest first.

Song Biao himself, accompanied by Chen Qicai and others, took a car to the Taiyuan Armored Engineering Research Institute on the outskirts of Jin County, because a very remote, cheap and complex large area of land was to be requisitioned in the surrounding area for tank testing, and the location of this research institute was still relatively remote, and the locals called this place Baicaopo, and the surrounding area was hilly.

When the car passed all the way, Song Biao saw all the hills and low mountains in the surroundings, because he was going to inspect, there were several soldiers standing guard and patrolling at a distance of 500 meters on both sides of the road, there were airplanes patrolling at low altitudes, and there were cavalry units of the patrol army on both sides to maintain vigilance on a large scale.

For so many years, Song Biao rarely encountered assassinations during his tenure as emperor, and the most successful assassination was hundreds of meters away from him, compared to President Lincoln, the security and security work around him was still very strict, and the absolute loyalty of the national military forces to him was a very important reason.

After the convoy drove into the institute, Song Biao first met with the main engineers, scientific advisers and representatives of Taiyuan Machinery and Vehicle Factory of the institute, and then visited the main achievements of the institute in the past 15 years under the arrangement of the institute, including the Jin 2 chassis currently used in China, which is basically the same as the American Christie chassis, the biggest difference is that the former adopts a six-wheel load-bearing design.

MBT series tanks MBT10 \ 20 \ 30 lined up, all parked in front of Song Biao's eyes, including self-propelled guns modified with MBT10 \ 20 as the prototype, after the end of the Sino-Soviet War, the Central Military Department of the empire has realized that the division of light, medium and heavy tanks lacks practical value, and what really determines the outcome in the war will be a more balanced tank, as long as the number is enough, it can overwhelming all wins.

This tactical thinking led to the birth of the MBT series of tanks, the prototype of which was the medium tank T4, which shone during the Sino-Soviet War, but the MBT10\20 tank and its modified self-propelled guns were not in large-scale service, and the T4 is still in service with the Imperial Army to this day, as well as the subsequent model T14.

The T series tank is a model and a number, and now the highest number is T15, in fact, only the T14 that was finalized and put into production in 1928 is really in large-scale service, and the 10\20 of the MBT series is a major overhaul of a model, and the MBT30 is a new tank that officially began to be developed in 1928, absorbing many new achievements of the T14 project, and there is only one prototype at present.

At first glance, this prototype of the MBT30 tank looks a lot like the Soviet T-34 tank in World War II, except that the newly adopted Jin-3 chassis adopts a torsion bar reading suspension system, which is not very stable, which is why the MBT30 was not immediately tested on a large scale.

Because the empire directly used the number of the T series very early, the Soviet Union in order to distinguish, they used the PT series number, that is, the meaning of the Soviet tank, a very important reason for this is that the earliest tanks of the Soviet Union almost all came from China, in 1925, the Soviet Union also bought the design and production drawings of the T-4 series of tanks from China, until today, there are thousands of T-4 tanks in service in the Soviet Union.

The Chinese T-4 tank was PT-4 in the Soviet Union, and the two tanks developed by the Soviet Union continued to use the number of the PT series.

China is now walking on two legs, the main battle tanks of the MBT series are also engaged, the conventional light, medium and heavy series of T tanks are also engaged, light, medium and heavy are numbered by the T series, and the infantry fighting vehicles are numbered by the BM series.

An important difference between the MBT and T series is that the former is more expensive, and if you want to use the mobile surname of a medium tank to achieve the defense and firepower of a heavy tank, it is obviously only more expensive, using the best engine, the best defensive armor, the best artillery, the best metal materials and homogeneous armor.

The MBT30 tank is still in the process of development, and it is said that it can be put into service, and it is still far from real maturity.

Song Biao felt good after watching it, but he didn't say that he could be put into service first to see the effect, but told Chen Qicai to continue to increase the work in this area, especially the development of the 88mm cannon should also be accelerated.

By this period, many of Song Biao's influences on the military industry could be seen, such as the design group that had been established in the empire to carry out theoretical research work on composite armor to deal with the threat of armor-piercing shells.

Of course, one of the most important advantages of the Imperial industry over the United States and the Soviet Union at this stage is engine technology, and the Reich has tested new diesel engines in the MBT series of tanks, and this 12-cylinder diesel engine is rated at 550 horsepower.

In order to further expand the tonnage of the MBT series of tanks, the empire is now investing all manpower and material resources to strengthen the research of the engine, the goal is directly aimed at the 750 horsepower engine, at this stage a more reasonable possibility may continue to increase the displacement and cylinders, or the use of mechanical increase technology, theoretically can also use the French proposed turbocharging, but like axial flow turbojet, both need special alloy materials that are resistant to high temperature and high pressure, and this series of materials has no research topics in the world at present.

Either way, a breakthrough must be made in new metallurgical materials, otherwise mechanical augmentation techniques can only be used.

Therefore, the highest level of industry often depends on the most basic foundation, fortunately, the Imperial 201 project from the beginning of the special focus on the metallurgical industry and alloy materials research, the annual investment is very amazing, the level of the imperial metallurgical industry can also be called the world's leading, if the empire can not solve this problem, other countries can not solve the problem, including the United States, under the control of the Far East consortium, the metallurgical industry of China and the United States is basically united, China has the technology, the United States may not have, the United States has the technology, China must have.

The United States has not yet realized that this problem is very dangerous, and when the United States realizes it, it is estimated that China will not need to continue to develop together with the US metallurgical industry, and according to the speed of China's development in the field of metallurgical industry and heavy industry, China will basically wait another five years, at most ten years, and China will no longer need to tie up the US steel industry.

Song Biao did not stay too long in the Taiyuan Armored Engineering Research Institute, and after a general look, he went directly to the Taiyuan Aircraft Factory, where there are now six turbojet fighters in China, which belong to two different models, two in Shenyang, one in Taiyuan, and the last three in Yinchuan.

At present, the problem of whether there is or not is basically solved, in fact, the two models do not have the technical conditions for service, because from the very beginning, the Fudao aircraft manufacturing company, which has the best technology in China, is responsible for Shenfei and Taifei, and it is relatively normal to have problems.

Shen Fei's side is a more conservative plan, agile surname and low altitude are more advantageous, Taifei's side is high speed surname Neng, high altitude advantage, the air force did not deny any plan, the two together.

These two companies are also different, Shen Fei is a subsidiary of the Far East consortium, Taifei is a state-owned Shanxi consortium enterprise, many of Taifei's technology sources come from France and Germany, so far, there are still many engineers in Germany, but these people belong to special contracts, it is basically impossible to leave China. The salary is so high, and the top secrets of China are mastered, and it is impossible to let them leave China.

A very important reason why a country with a vast territory, a large population, and abundant resources like China and the United States is easy to rise is that its per capita income may not be as good as that of Britain, France, and Germany, but its central finance is no worse than that of European countries, and its per capita output value is still inferior to that of the United States, Britain, France, and Germany in 1931, but in terms of total economic scale, China has been on a par with the United States, which is equivalent to the sum of Britain, France, and Germany.

As recently as 1931, China's central fiscal revenue was already higher than that of the United States, and there was still a certain gap between the per capita income and that of Britain, France, and the United States, and the per capita annual income was only 1/4 of that of the United States.

According to the current plan, the per capita income of Chinese will increase by another 70 percent by 1937, and China's total economic output will exceed that of the United States by about 75 percent.

This is really not something that the United States can intervene in right now.

When the per capita income and per capita GDP of Chinese are on par with those of the United States, it is normal for China's total economic output to exceed that of the United States by three or four times, and the total economic output accounts for 1/2 of the world, and if there is no World War II, it will basically reach this scale around 1950.

China will never wake up, and if it wakes up, it will alarm the whole world.

Since the establishment of the empire, it has been like 20 years of reform and opening up, and the development of 20 years has been earth-shattering, there is neither a technical blockade, nor a political obstacle, from the early German and Russian support to the Franco-Russian support in the middle period, and finally the support of the United States and France and the large-scale recruitment of talents from Germany and Russia.

Even if many important scientific research projects in the empire are still in progress, as the emperor, Song Biao is also quite leisurely to sit and watch the world change, after two days of inspection in Taiyuan, Song Biao took a car to Qi County.

At this time, Shanxi Province has some special features in the administrative division, with nine provinces and one state, Qi County is the Zhili County outside the nine provinces, and Pingyao County is merged into Qi County, because the status of Qi County is special, Shanxi Province has more emphasis in the railway construction plan, making its status more important, and the business is prosperous.

After arriving in Qi County, Song Biao and Qiao Guifei still lived in the Qiao family compound as usual, this time when they came to Qi County, Song Biao did not have to ask about anything, but just symbolized the surname to accompany the concubine back to her mother's house once, live for half a month, and enjoy the cultural scenery in Qi County.

Qi County can be said to be the most concentrated area of Shanxi tourism resources, which is also related to the culture of Jin merchants, the local Qiaoqu two compounds can be called the pinnacle of Shanxi folk houses, the Central Institute of Architecture in order to determine the improved design and beautification of Shanxi folk houses, has been to the ancient city of Qi County and Qiaoqu two compounds four times to investigate.

Walking in the ancient city of Qi County like an idle cloud and a wild crane, walking in the aisle of the Qiao family's compound, admiring these gray bricks and black tiles of northern residential buildings, and feeling the atmosphere of this traditional era, what Song Biao can experience is a kind of luck, a kind of luck that has never been destroyed.

It is really not easy for China to have such an era!

As a Chinese, he was so admiring and rejoicing.

With the large relocation of the population to the four northern provinces and Novosibirsk, the population of Shanxi has decreased from 44 million at the beginning of the founding of the People's Republic of China to 27.4 million, and the development of industry and mining and the advancement of urbanization have greatly reduced the pressure on local agriculture, and this stage is when the water and soil pressure in Shanxi is the lightest.

All this has laid a good foundation for the management of the Loess Plateau, and the work of returning farmland to forests has been carried out very smoothly, with more than 200 townships and towns on both sides of the Yellow River returning 440 million mu of terraced fields to forests, mainly planting economic forests and walnut forests.

One of the fundamental reasons for this is that world grain prices have fallen sharply, the country's grain output has been rising steadily, the per capita income has increased so that the income from farming is far lower than in the past, and the central government and Shanxi have also given relatively large subsidies to forestry.

Song Biao remembered that the last time he came here to inspect, he could easily see the soil and tobacco fields in the mountains and fields, the terraced fields were dense, and the barren slopes on the Loess Plateau were thousands of miles, but now they have all changed.

Shanxi's return of farmland to forest is a new policy that has only begun to be implemented on a large scale in recent years, and the vast majority of walnut and chestnut trees planted in the forest area are still at the seedling stage, but in the spring, it happens to be the time when ten thousand trees return to green, and there is a different taste at a glance.

Although the empire has a population of 470 million, the territory is more than twice as large, and the political axe also forcibly promoted the migration of people to work during Wang Yongjiang's four terms as minister of agriculture, and the industrial efficiency is not like the 21st century, with the development of industry, the urbanization rate is easier to promote.

After finishing his trip in Shanxi, Song Biao took a special plane China No. 1 to fly to Shanghai to participate in the opening ceremony of the first China National Sports Games, and at the same time to meet in Shanghai with the new foreign minister Kenkichi Yoshizawa and the father of judo, Jigoro Kano, this visit to Shanghai has received great attention, because Shanghai is also the venue of the fifth Chinese judo challenge in June this year, and the first National Games and the fifth Chinese judo challenge will also be held in Shanghai almost at the same time.

Under Song Biao's arrangement, China's National Games will be held every year on May 1, which coincides with the long holiday of International Labor Day.

The empire was very good at avoiding the impact of the left, and realized that the 51 proletarian common festival advocated by the International Proletarian League was renamed International Labor Day, and it was a seven-day long holiday in China that was determined to be equivalent to the Spring Festival and National Day, while New Year's Day, Mid-Autumn Festival, Dragon Boat Festival, Double Ninth Festival, and Lantern Festival were only three-day long holidays.

China has a long history, there are countless cultural inheritances, and it is normal to have many festivals, which is also a great news for the working class, and it is more beneficial to the development of the capital market.

In order to fit the theme of the National Games and International Labor Day, the athletes of the National Games are all non-professional surnames and are selected from farmers and workers, and the National Youth University Games and the National Youth Games are selected from students.

So in the last three Olympic Games, the empire has chosen to refuse to participate.

It's a matter of time before you participate, it's just that you either don't participate, or if you want to participate, you have to make a splash and toss a big event.
