Chapter 71: Chinese tiger

It's August soon.
Feng Ruhai and Professor Hua Mingyuan from the School of Aeronautics at Southwest University stood in Zhang Shusheng's office. Waiting for him to make a final decision. There were two reports on the table.
After Zhang Shusheng read the report they handed in, they signaled the two to sit down and said, "The movement in the southeast is not slow. The new aircraft successfully tested the flight so quickly."
The other report on the table, opened, is a photo of the aircraft, a biplane of the old aircraft, marked below: the first aircraft designed and produced by China itself-Luo Shiwen No. 1, Guangdong, Dashatou Airport and other words .
Feng Ruhai also looked at the internal reference forwarded by the headquarters of the Mindan League to the Institute of Aeronautics, commenting on the performance of this aircraft: "Yang Yixian still has some ability. Depending on the parts and components bought back, this biplane can be built. It's rare. "
Zhang Shusheng was extremely satisfied with this young man. He could not see the immatureness of his peers at all. At the age of 20, his performance in all aspects was enough to win the word genius.
"If you can't afford it economically, you're afraid you won't be able to make a few old biplanes." Zhang Shusheng knew better than anyone about the situation in the southeast. Feng Ruhai was anxious to be overtaken by the southeast. He didn't worry about this. "In this way, Professor Hua, how confident are you with your plan to build a larger low-speed wind tunnel?"
During the construction of the wind tunnel that year, Zhang Shusheng had no worries about his hair, and repeatedly experienced failures and pains. Technicians and construction teams rushed to work two days a day and night to build the low-speed Zhushanping No. 1 wind tunnel.
Don't look at it. This is just a small low-speed wind tunnel with an air velocity of less than 130 meters in the experimental section, but it has contributed to the successful development of the J-1 aircraft. Although almost all of the aircraft's key data, Zhang Shusheng, can be produced, such as the aerodynamic layout and detailed design of the fuselage, the actual development process and the process of testing the fuselage still use this wind tunnel. After a while, technical personnel were trained.
Otherwise, the data is the same thing. If the aircraft produced does not pass the wind tunnel test, it may disintegrate as soon as it is tested for flight.
"District chief, the theory and technology of the wind tunnel, you said last time that there are some ready-made technical reserves in the civil group system. I think that although the construction of small and medium-sized wind tunnels will be difficult, it is only a matter of time The current Zhushanping No. 1 wind tunnel has been unable to support the development of more advanced aircraft. After the development of the J-1, the fighter development team has initiated the development of the more advanced J-2. So, this wind tunnel Is urgently needed. "
"Well, I approved this project. I hope you can show your enthusiasm for the construction of wind tunnel No. 1 and strive to build this small and medium-sized wind tunnel in a few years." Zhang Shusheng took out his pen. I personally signed my name on this detailed plan. After the final decision, with the district government's high efficiency, the first phase of research and development funding will be available within a week.
Although the group's technology has developed for eight years, with Zhang Shusheng's technical support and vigorous procurement of foreign machinery and equipment, it is still far inferior to the West.
We can only take such a small step and run fast method, by concentrating resources and technical personnel, to carry out some key technical problems. Take the success of an airplane, for example. It's not that the overall technology of the Mindan League is more powerful, but that Zhang Shusheng has desperately developed it like Sanlang.
"Great!" Feng Ruhai and Hua Mingyuan are both very happy. The wind tunnel is an important part of the aviation industry. Only with a better wind tunnel can we develop more advanced aircraft.
Zhang Shusheng emphasized, "Professor Hua, the aeronautics school has become heavier after independence from Southwest University. In addition, such as the current shortage of personnel, you have to focus on the newly formed pilot school. Light has The plane will not work, and there must be qualified pilots. "
"Relax, Mayor Zhang. The foundation of the aerospace college is unshakable, it's just independent."
"The mayor is assured. At present, the flight school is mainly the three pilots currently in the base and a few returning international students are serving as flight instructors. The institute mainly sends some highly skilled theoretical experts to teach flight students. Twenty students in the first period have two to three actual flying opportunities per week. (The training aircraft is an old-fashioned biplane.) The overall research staff is still seriously inadequate. I hope that the mayor can think of ways. "
Regarding the lack of people, Zhang Shusheng knew that there was a shortage of people in every department and research institute. For example, the Aviation Research Institute will soon be divided into one and two, one responsible for the development of fighters, and two responsible for the development of bombers. Due to cost considerations, although the performance of the J-1 is not advanced enough, it is fully in line with current needs. On this basis, the bomber-1 bomber with a 1.2-ton bomb capacity developed and developed will also be equipped with a batch of .
After the two went out, Zhang Shusheng picked up the phone: "Hello, I'm Zhang Shusheng, please pick me up from the principal of Lishuping No.1 Middle School."
"District chief, my name is Xiao Xueneng." After the transfer at the headquarters communications office, a voice came out quickly. "Principal Xiao, in a few days I will specially grant a student named Qian to your school, yes, it is a freshman. Well! No special care, but try to provide him with some learning conveniences, such as teacher guidance and library lending And the like, give him the highest borrowing rights. "
Hanging up the phone, Zhang Shusheng was slightly surprised, then raised the corner of his mouth slightly, took a clean work clothes hanging on the side and went out. Today is an important day.
The proving ground, five kilometers east of Lishuping, is another military test base for the militia.
"Sterman, this guy you made is really big."
A steel monster was parked on the proving ground. The high muzzle and mighty juxtaposition machine guns gave way to those standing nearby. I felt a puppet belonging to the war beast. Although Zhang Shusheng has seen this monster many times, every time he sees it, he will feel the power of this war machine.
The tank named Tiger Ⅰ is the final result of a team of Chinese and foreign scientists led by Shideman in the past few years.
"Zhang, except that this tank is a little heavier, everything else almost meets your requirements. You see, this powerful 75mm tank gun is a masterpiece of Huffman. In the face of our German chicks, it is a shot They can tear them apart. "Today, Schedman is already in the midst of several dozen people. After the family's foundation was completely destroyed, he took his family to find a new life in China. Together with Huffman, a former brother, he devoted himself to the research and development of the new tanks of the civilian group.
"Boss, don't worry, those little girls in Europe will be pushed down one by one in front of this big guy, hahaha ..." Huffman also laughed. After being abandoned by the motherland, these two guys who left the wave shape have completely lost their hearts, especially Huffman. All these years in Xiaoqingshan have been very comfortable, and they eat and drink every day. They also maintain close relationships with two or three German female staff members in the Dongchuan area.
"The test will begin." Zhang Shusheng nodded and ordered the test to begin. Two domestic scholars and two security personnel climbed into the tank.
"Boom ~" After a violent diesel engine blast, a large cloud of oil fume was sprayed from the buttocks of the tank. In the sound of the booming engine, the tank first trembled, and the track was driven by the drive wheels to run over the lawn of the test site stand up.
The sound of the engine was getting louder and louder. The tank ’s 400-horsepower diesel engine gradually increased the tank's speed to an hourly speed of 20 km / h, and the blast rumbled towards the distant shooting range.
While feeling the vibration from the ground, Zhang Shusheng took the telescope from the security personnel next to him, and saw that the Tiger I tank smoked all the way to the shooting range more than 1,000 meters away.
"boom!"
The tank fired its first gun at the hillside facing the shooting range. The telescope can see a huge explosive smoke rising from the mountainside.
"Da Da Da ..." Although the sound of heavy machine guns was no more than 1,000 meters away, in parallel high-powered telescopes, tank side-by-side machine guns were still seen firing wildly.
The tanks that had already finished a certain amount of shells and ammunition received a return order from the on-board radio.
"Zhang, what about this tank? Didn't let you down. Large-caliber tank guns, low defense design, heavy armor, fire control equipment, and on-board radio equipment."
Shideman put down the telescope with satisfaction, full of pride in his heart. Although he has lived happily in China in recent years, he did not get a strong sense of pride and honor until the tiger was born.
In his words, he doesn't have to belong to Germany, but he must be loyal to honor. Therefore, he chose to stay in the militia, because there will always be tank research work that excites him. His goal was to leave a name in the history of the tank.
Zhang Shusheng nodded, this Tiger-type Ⅰ tank using a 400-horsepower diesel engine, the design prototype is the German Tiger-type tank ten years later. Although the data and technical indicators in various aspects are much worse, such as the engine's horsepower is half less, the design concept is extremely correct.
Low tank body, heavy construction site, enhanced climbing performance. The vehicle has 4 members, the front armor reaches 60mm, is equipped with a 75mm tank gun, has 40 rounds of ammunition, and a 7.92mm parallel machine gun. The maximum road speed is 25 km / h.
Overall, this is a powerful tank. The only drawback is its weight: 28 tons.
If this weight is placed in Europe, the highway is vertical and horizontal, and the transportation is convenient, it will be a trivial matter in the environment of Yipingping. However, today's southwest, except for the county roads of the main roads, which can access ordinary highways, it will be blank. Only a small road. In addition, in the southwest, there are many paddy fields. In this case, if the 28-ton tank is used for field operations, it may even get stuck in the rice field and cannot climb out.
After the test, Zhang Shusheng called Schedman and a German expert, several domestic scholars and technicians, "I am glad to see that you have built such a powerful tank. However, some practical problems, we But we must pay attention to it. For example, it is too difficult to manufacture, and large-scale production was difficult to achieve at least before 1927. The cost of a single tank is too expensive. If a division is equipped, I may go bankrupt tomorrow. In other aspects, the speed is too slow. Engine manufacturing issues, steel issues, are difficult for us to overcome in a few years. "
"Zhang, the development of this tank is very difficult. You can't throw it back to the steelmaking furnace and recast it in one sentence." Shideman also understands these problems, but he is really difficult to resist the design of a successful set of firepower The seductive power of an advanced tank with speed, defensive power.

"This kind of tank can be equipped with a small amount. I also organized discussions with other experts and came up with another tank solution that is more suitable for the current use of civilian groups."
Zhang Shusheng took out a drawing and showed it to them.
"Light tank?" Schedman wondered.
Zhang Shusheng: "Yes, I hope you can complete this Tiger II light tank as soon as possible. The Tiger I medium tank will only be equipped with a small number of elite troops, and the Tiger II tank will be equipped more."
The reason why they started to develop the more difficult Tiger I tanks was to make enough technical reserves. While developing medium tanks, the light tanks that have been mainly used in recent years have developed better.
---------
The current two or three technologies of the People's Regiment are all concentrated and developed. Zhang Shu gave a lot of effort. In the next few years, the development of science and technology should be more logical. The emergence of tiger tanks and fighter aircrafts is just a start-up. Start. The latter will be more logical.
