After more than a year of large-scale industrial construction, the types and scale of industries in Taiyuan Administration, Suiyuan, and North and South Mongolia have undergone tremendous changes, and the results of development and construction have begun to gradually appear.

Song Zhewu's Aviation Research Institute has developed new models of fighters, reconnaissance planes, and attack planes, and is now doing its final test flight debugging.

Although the Fourth Route Army's own aero engines are still being intensively developed, and the engines of these three new models are still imported, it only took more than half a year to come up with these three new aircraft, which is still a bit surprising.

At first, Song Zhewu even didn't believe it, because this time was too short. However, Song Zhewu quickly figured out the reason.

At this time, the design and construction of aircraft were far less complex than those of later generations, and were relatively much simpler. In foreign countries, as long as there is money, even individuals can build airplanes, not to mention that in his aviation research institute, there are now a number of top experts and scholars such as Ba Yuzao, Wang Zhu, Wang Xiaofeng, Zeng Yijing, etc.

Song Zhewu was very happy that in such a short period of time, he had his own aircraft with almost complete intellectual property rights, but Song Zhewu still resisted the strong urge to see his new aircraft with his own eyes.

Song Zhewu knows very well that in terms of aircraft design and manufacturing, compared with experts such as Ba Yuzao, he is actually an out-and-out layman. According to the memory of his own previous life, it is okay to give some guidance and suggestions to these experts in terms of advanced concepts and the direction of aircraft development, and even provide some advanced improvement methods in some technical links. However, in his limited memory, there was not much about airplanes anymore, and even if he went, he would not be able to help much.

If it is officially put into operation, according to Wang Zhu's estimates, it will be able to produce about 10 aircraft per month, and in the future, with the improvement of production technology and the rationalization of production technology, as well as the localization of all parts of the aircraft, the output should be increased by another 50 percent.

Although this output is far lower than Song Zhewu's requirements and needs, he has no better way, to build a large aircraft factory, not only needs a large amount of equipment, but also needs a large number of skilled skilled workers with a certain amount of experience, but it will take time.

Now, if it were not for the engineering and technical personnel from Europe and the United States, as well as overseas Chinese engineering and technical personnel and skilled technicians hired by Wang Dong and Li Rujuan, who helped train and participate in actual production, it would not have been possible to produce even five planes a month, not to mention ten planes a month. At least he doesn't have many skilled mechanics who can skillfully control machine tools to process high-quality parts.

The quality of the aircraft surname can have a great relationship with the processing technology of all the components that make up the aircraft, it is one thing to have drawings, and it is another thing to manufacture them, and even the aircraft manufactured according to the same set of drawings, different countries, and even different manufacturers have some differences.

In today's absence of CNC machine tools, the quality of aircraft parts and the level of processing accuracy completely depend on the technical level of the technicians who process these parts. This matter is indeed urgent.

However, fortunately, in terms of quality and speed, Song Zhewu and Ba Yuzao and others have reached a consensus, that is, even if the production and manufacturing speed is lost to a certain extent, the quality must be guaranteed, which is a big matter related to the life safety of pilots.

Of course, Song Zhewu will not now, or he does not have the ability to strive for perfection like the workers of Xiang, he will not demand perfection. In the manufacture of aircraft, and even in the manufacture of other weapons and equipment, it is still necessary to strive for simplification on the basis of guaranteeing the ability of the surname.

Like the Aviation Research Institute, Guo Wenyuan's Machinery and Equipment Research Institute has also come up with the latest tank prototype, which has been greatly improved in all aspects compared with the original prototype in terms of cross-country ability, firepower, and flexibility.

This tank, Song Zhewu has been to see, this prototype is very similar to the famous T-34 of the Soviet Army in World War II. The most gratifying thing is that this tank even achieved partial hydraulic transmission.

The only deficiency now is that the tank gun and protective armor steel are still not up to par.

Song Zhewu found that he still overestimated his own strength, his technical force is still too weak, although there is a technical patent for armor steel, but the quality of the trial armor steel is still not as good as imported, it seems that it is not possible to develop qualified tank guns and armor steel in a short time.

Then there is the problem of tank engines. Wang Dong has developed a new model of high-power diesel engine, which makes the 35-ton tank reach an astonishing 50 kilometers per hour off-road speed. It's just that the technical state of this new model of diesel engine is still a little unstable, not to mention that it often stalls, and the service life of individual components is not high.

The results of the automobile factory are the most remarkable, and the three trucks of the "Iron Horse", "Puma" and "Hummer" and the "Tiger Tiger" Jeep have all been mass-produced. Among them, the production of "Iron Horse" and "Hummer" is smaller, and now it is twenty units per month.

This is not the reason for production technology, because the production equipment is basically bought as a whole eighty percent new, and the technology is also at the advanced level of today's foreign countries, and the problem lies in the management technology.

Although Ford took the lead in setting up an assembly line in 1913, this advanced production method was not widely adopted, as was the case with the automobile factory that Wang Dong bought. However, even so, the output of the automobile factory is several times larger than this output, and now this output is the result of Xiao Guodong's deliberate limitation.

The reason is that the weight capacity of the "Iron Horse" brand truck is only 2 tons, because it is not designed as an off-road vehicle, and the body structure is relatively thin, so it cannot be used as a military vehicle. And the short and stocky "Humvee" is designed for towing heavy artillery. The problem now is that Song Zhewu's troops have very few heavy artillery pieces with a caliber of more than 100mm, and there is no urgent need for a large number of such trucks for the time being.

However, in order to continuously improve the ability of the car surname and accumulate design and production experience, these two cars still need to maintain a small amount of production.

In the three months since the official production of these cars, 45 "Hummers" have been produced. Twenty-five of them were handed over by Xiao Guodong to the Northern Mongolian Front Command presided over by Li Wentian in Northern Mongolia to tow the dozens of heavy artillery, and the shortfall was made up later. The remaining twenty were all given to the Central Teaching Corps by Song Zhewubai.

The reason why Song Zhewu did this was because with the help of the German adviser Weitzel, he was preparing to train the German armor division on the basis of the teaching corps, although the German armor division was not equipped with heavy artillery, only 75mm mountain artillery, but it would be equipped with some heavy artillery in the future, such as the famous 10th and 14th artillery regiments were equipped with German 150mm howitzers. Song Zhewu's purpose was mainly to let the Central Army know that domestically produced trucks were also very useful, and that they should not buy everything from abroad, and the meaning of creating a brand for advertising was very obvious.

Dozens of "iron horses" were all sold by Song Zhewu. The "Iron Horse", which costs 2,800 oceans per vehicle, caused a sensation as soon as it was put into the market, and was snapped up by private transportation companies in Taiyuan that urgently needed to expand the scale of transportation.

Due to the rapid development of industry and commerce in Taiyuan, not only a large number of raw materials purchased have to be transported in, but also a large number of goods produced have to be shipped out as soon as possible after they are sold. However, the capacity of Zhengtai Road is limited, not only the freight rate rises rapidly, but sometimes it has to wait in line for more than ten days.

Because the Zhengtai Road was full of capacity, the profits of the Zhengtai Railway Administration soared, which made the new Minister of Railways, Gu Mengyu, who had been re-accepted by Chiang Kai-shek, overjoyed, and if this state of affairs lasted for a few years, he would have the money to build a new railway.

For this reason, Gu Mengyu not only called Song Zhewu to contact him, but even instructed Wang Maogong, director of the Zhengtai Railway Administration, to personally rush to Taiyuan to discuss with Jia Jingde the construction of a railway to Datong in the Daixian section of the Taiku Railway, so as to connect the Pingsui Line with the Taiku Railway to realize intermodal transportation and increase transport capacity.

For Gu Mengyu's suggestion, Song Zhewu is very supportive, if the Heping Sui Line is really connected, it will be more convenient for the goods of the Taiyuan Administration to enter and exit. And even if the Anti-Japanese War really hits Shanxi in the future, he is not afraid that the little devil will use this railway, the Pingsui line and the different tracks he built, if the little devil wants to use his railway, then he must have his locomotive and carriages, these things will definitely not remain in Datong.

However, the construction of the branch line from Daixian to Datong is not up to him Song Zhewu, whether it can be completed depends on Xu Yongchang's attitude.

However, although Xu Yongchang is also happy to have such a railway, it is only for a moment, because he has no money. Although this section of the railway is not long and does not require too much money, he still can't afford to repair it, and now the military expenses of the Jin Sui army are a headache for him.

And if Song Zhewu pays for the repair, then this section of the railway will be managed by Song Zhewu, although Xu Yongchang does not object, but none of the generals of the Jin Sui army agree. Xu Yongchang had no choice but to give up.

However, this matter has taken a turn for the better after Yan Xishan returned, and according to Wang Maogong's telling Jia Jingde, Yan Xishan was already discussing this matter with Gu Mengyu.

It's just that far water can't quench the thirst of the near, and even if the construction of this railway starts immediately, it will take a year or two after it is built. Moreover, even if it is completed, looking at the current development momentum of the Taiyuan Administration, it will still not be able to meet the needs of the Taiyuan Administration for the import and export of goods, and the automobile transportation will be prosperous.
