Zhang Yuanzhi, who has Xu Zhining as the translator, spent several days to read the dozens of journal papers circled by Liu Xuanxin, and figured out the problems left when reading "Introduction to Anatomy".

Just when Zhang Yuanzhi was still unsatisfied and wanted to continue soaking in the library, Ma Xuanzhong received a telegram: dozens of trucks had arrived in Jiuquan.

In the days that followed, Zhang Yuanzhi was also able to see what General Political Commissar Zhou Xiangyu called the "mysterious" Hexi Corridor in its entirety.

The special train of the New Second Army set off from Xining and went straight to Jincheng, and just when Zhang Yuanzhi was curious about whether it was going in the wrong direction, the special train turned around in Jincheng and turned back.

Zhang Yuanzhi found that unlike the railway to Qinghai, after the train passed Tianzhu, all the personnel at the station were dressed in brown military uniforms; And along the railway line, large military camps can be found at intervals.

And contrary to Zhang Yuanzhi's prediction, along the railway line laid along the Hexi Corridor, in addition to the hills planted with pine trees, you can see the plains that are tightly blocked by dwarf trees; Even around Jincheng, which is located on the Loess Plateau in northern Shaanxi, it is rare to see bare loess.

Whenever they arrived at a military station, the special train would stop for a while, and by the time Zhang Yuanzhi saw the towering blast furnaces of Jiuquan Iron and Steel, everyone had been on the train for several days.

After putting Liuyun and his party down, Ma Xuanzhong returned to the special train and left Jiuquan with condolences.

When he arrived at his own territory, Liu Xuanying became a chatterbox, and on the way from the gun workshop to the rolling mill, he kept introducing various workshops on the roadside......

In the vehicle workshop, when he saw thirty all-wheel drive sixteen-wheeled large trucks, Qin Yugang also felt that these tires were behemoths as tall as one person, and it was more suitable to convert them into armored combat vehicles.

However, after circling around the trucks, Qin Yugang vaguely felt that the original design and use of these trucks might not be civilian transportation, and as for what they did, Qin Yugang couldn't say.

However, when he lifted the front of the car and saw the displacement of up to forty liters and the power of more than 500 horsepower on the engine nameplate, Qin Yugang also understood Ma Xuanzhong a little: These big guys, if they are not converted into armored combat vehicles, it is really a bit of a waste!

Liuyun glared angrily at Liu Xuanling, who wanted to drag race: in order to maximize the use of the existing processing capacity, he plagiarized the design of Lao Maozi's MAZ-543 twenty years later; Although the design has been optimized, it can be inherited from Lao Maozi's stupid big black coarseness, which makes the fuel consumption of these big guys distressed.

Although more than half a century later, it is said to be stupid and coarse, but in this era, high-horsepower all-wheel drive trucks are still very advanced in design, and the difficulty of production is not ordinary.

Just to produce the aluminum engines taken from the T54 tanks, the electrolytic aluminum plant that was launched ahead of schedule has drained the excess power from the power grid near the steel plant.

In order to improve the hardness of parts, the mechanical processing plant has added a batch of heat treatment and forging workshops.

In order to produce gearboxes that can match high-horsepower diesel engines, the steel plant has set aside several in-house electroslag recasting machines for the refining of gearbox alloy gears and box blanks.

As for the steel radial tires that can carry more than 30 tons of weight, the northwest only produces the inflation and deflation system, and the tires are produced by the mining machinery company set up in the United States by Wu Yucheng, the fourth apprentice of Liuyun; The prototype of the self-use mining truck produced by Wu Yucheng's mining machinery company is the chassis of the later Swedish FH-77BDL52 self-propelled gun, and the chassis of Volvo's six-by-six articulated truck.

In order to control the quality of the engine and gearbox products, Liu Xuanying led a turtle team of nearly 200 people, and after several months of continuous testing, compiled nearly 3,000 pages of process specifications......

After the first batch of prototypes rolled off the assembly line and completed the all-terrain test, Liuyun began to rejoice, fortunately, he had picked up garbage for hundreds of years, or he would have lost it.

After the production of ten batches of 120 vehicles, Liuyun understood the reason why the Chinese Communist Party likes to engage in technical breakthroughs.

The junior technician who has worked on the production line for more than a year successfully passed the intermediate technician assessment during the skill assessment.

The technical team, which had not previously been exposed to all-wheel drive trucks, after digesting the technology of the engine and transmission, continued to experiment and improve, and succeeded in increasing the power of the engine to almost six hundred horsepower.

In fact, the northwest already has the ability to produce main battle tanks, but because China is not really a big country, and moreover, many metal deposits in the northwest can only be said to be better than nothing, once the large-scale production of armored equipment, the non-ferrous metal inventory that Liuyun secretly accumulated in Jiuquan will soon bottom out.

And Ma Xuanzhong, because he didn't know how to finish the tank, didn't know that the more than 100 trucks under his hands, dismantling the engine and gearbox, and installing the turret and turret, were tanks.

The Southern Xinjiang Railway, which has been extended to Kashgar, plays an extremely important role in Liuyun's planning: after the outbreak of World War II, various mineral resources in Australia, especially uranium ore, will be transported from Wu Yucheng's ore port in Western Australia to Karachi Port, and then through Pakistan along the Southern Xinjiang Railway to Jiuquan for storage; What's more, this line is close to the Persian Gulf, which is extremely convenient for the future transportation of oil in China......

Before arriving at the gun factory, Liu Xuanliang asked the driver to stop, said goodbye to everyone, jumped out of the car, and rushed back to the Jiuquan Information Center outside the car window.

Looking at Liu Xuanliang's eager back outside the car window, Liu Xuanying patted the seat in front of him: "Dad, another person's heart in our family has been stolen." ”

Liuyun was stunned for a moment, turned his head and looked at Liu Xuanying curiously: "When did it happen?" ”

Liu Xuanying smiled: "Then I don't know very well, I only know that in the second sequence of the Guided Weapons Research Institute, there is a studious little girl who runs to the data center every day." ”

Liuyun nodded: "Oh, my own people." ”

Liuyun, who had already turned around, seemed to remember something, turned around and asked, "Xuanying, how is the 155-mm artillery project of 39 times the caliber going?" ”

Liu Xuanying frowned and thought for a while before answering: "There is basically no problem with ammunition; There is no problem with artillery elsewhere, and even the complex high and low mechanisms have benefited a lot because of the truck project; The most troublesome thing is the bolt, if the bolt is threaded, the rate of fire of the gun will not rise, and with the wedge bolt, sealing is another problem. ”

As soon as Liuyun heard it, he understood that it was the evil consequences of his own "leapfrogging" development; However, there is no way, if you don't have a stick in your hand, anyone who sees it will rob it.
