August is quickly approaching.

Feng Ruhai and Professor Hua Mingyuan from the School of Aeronautics of Southwest University stood in Zhang Shusheng's office, waiting for him to make the final decision. There were two reports on the table.

After Zhang Shusheng briefly read the report they handed over, he motioned for the two of them to sit down and said, "Southeast's actions are not slow either. The new aircraft successfully completed the test flight so quickly."

The other report on the table opens to the first page, which is a photo of an aircraft, an old-fashioned double-winged aircraft, with a label below: The first aircraft designed and produced by China - Luo Shiwen No. 1, Dashatou, Guangdong.

Words such as airport.[

Feng Ruhai also read the internal reference forwarded by the militia headquarters to the Aviation Research Institute, and commented on the performance of this aircraft: "Yang Yixian is still somewhat capable. He was able to build this biplane with some purchased parts.

It’s rare.”

Zhang Shusheng is extremely satisfied with this young man. There is no immaturity in him at all compared to his peers. At the age of 20, his performance in all aspects is enough to be called a genius.

"If the economy doesn't improve, I'm afraid we won't even be able to build a few old bi-wing aircraft." Regarding the situation in the southeast, Zhang Shusheng knows better than anyone else. Feng Ruhai is anxious and afraid of being overtaken by the southeast, but he doesn't care about this.

Worried, "So, Professor Hua, how sure are you of your plan to build a larger low-speed wind tunnel?"

During the construction process of the wind tunnel, Zhang Shusheng almost turned his hair gray. He experienced repeated failures and pains. The technicians and construction team worked day and night for two years to build the current Zhushanping No. 1 low-speed wind tunnel.

Although this is just a small low-speed wind tunnel with an airflow speed of less than 130 meters per second in the experimental section, it has made great contributions to the successful development of the J-1 aircraft. Although Zhang Shusheng can produce almost all the key data of the aircraft.

, such as aerodynamic layout and detailed design of the airframe, etc., but the actual development process and testing of the airframe still use this wind tunnel, which not only allows scientific researchers to demonstrate the data, but also trains technical personnel.

Otherwise, data is one thing. If the built aircraft is not tested through wind tunnel experiments, it may disintegrate as soon as it takes flight.

"District Chief, regarding the theoretical technology of wind tunnels, you said last time that there are some ready-made technical reserves in the militia system. I think that in this way, although there will be many difficulties in the construction of small and medium-sized wind tunnels, it is only a matter of time before they are completed.

.The current Zhushanping No. 1 wind tunnel is no longer able to support the development of more advanced aircraft. After the completion of the J-1 development mission, the fighter development team has established a project to develop the more advanced J-2 aircraft. Therefore, this wind tunnel

It is urgently needed.”

"Okay, I have approved this project. I hope you can use the same energy as when building the No. 1 wind tunnel and strive to build this small and medium-sized wind tunnel within a few years." Zhang Shusheng took out his pen and wrote in person on this very important document.

He signed his name on the detailed plan. Once finalized, with the high efficiency of the district government, the first phase of R&D funds will be in place within a week.

Although the technology of the militia has gone through eight years of development, with the technical support of Zhang Shusheng and the vigorous purchase of foreign machinery and equipment, it is still far inferior to that of the West.

We can only adopt this method of small steps and fast running, by concentrating resources and technical personnel to carry out research on some key technologies. For example, the success of the aircraft is an example. It is not that the overall technology of the militia is so powerful, but that Zhang Shusheng worked hard

Saburo gave the same priority to developing it.

"Great!" Feng Ruhai and Hua Mingyuan were both overjoyed. Wind tunnels are an important part of the aviation industry. Only with better wind tunnels can more advanced aircraft be developed.

Zhang Shusheng emphasized, "Professor Hua, after the School of Aviation became independent from Southwest University, your burdens have become heavier. In addition, Ruhai, there is currently a shortage of personnel, so you have to focus on managing the newly established pilot school. Only with this

If the plane is not good enough, you still need qualified pilots.”

"Don't worry, District Chief Zhang. The foundation of the Aviation Academy has not been shaken, it is just becoming independent."

"The district chief can rest assured that at present, the flight school mainly has three existing pilots at the base and several returned overseas students serving as flight instructors. The institute mainly sends some theoretical experts with excellent skills to teach the flight students. We strive to let the first

The twenty trainees in the first phase will have two to three practical flight opportunities every week. (The training aircraft is an old-fashioned biplane.) But overall, there is still a serious shortage of scientific research personnel. I hope the district chief can think of more solutions."

Zhang Shusheng is well aware of the shortage of people. Now every department and every research institute is short of people. For example, the Aviation Research Institute will be divided into one and two institutes. The first institute is responsible for the development of fighter jets, and the second institute is responsible for the development of bombers.

.Due to cost considerations, although the performance of the J-1 is not advanced enough, it fully meets current needs. On this basis, the H-1 bomber with a load capacity of 12 tons will be enlarged and developed in batches.

.

After the two went out, Zhang Shusheng picked up the phone: "Hello, this is Zhang Shusheng, please pick up Principal Xiao from Lishuping No. 1 Middle School."

"District Chief, this is Xiao Xueneng." After the transfer from the Headquarters Communications Office, a voice came quickly on the phone. "Principal Xiao, in a few days I will specially approve a student named Qian to come to your school. Yes, it is

Freshmen. Well! No special care is required, but try to provide him with some learning conveniences, such as teacher guidance and library borrowing, and give him the highest borrowing authority."

After hanging up the phone, Zhang Shusheng was slightly lost in thought. Then he raised the corners of his mouth slightly, took a clean work clothes hanging nearby and went out. Today is an important day.

The test site located five kilometers east of Li Shuping is another military test base of the militia.[

"Schidemann, this thing you built is really big."

A steel monster was parked on the test site. The raised muzzle and the powerful parallel machine gun made those standing nearby feel the ferocity of a war beast. Although Zhang Shusheng had seen this kind of thing many times,

It's a monster, but every time I see it, I will be impressed by the power of this war machine.

The tank in front of us, named Tiger 1, is the final result of a team of Chinese and foreign scientists led by Scheidemann in the past few years.

"Zhang, except that this tank is a bit heavier, it almost fully meets your requirements. You see, this powerful 75mm tank gun is the masterpiece of Huffman. Facing those chick-like tanks in Germany, it can fire one shot

You can tear them apart." Today, Scheidemann is already in his thirties. After his family's foundation was completely destroyed, he took his family to find a new life in China. Together with his former fellow sufferer Huffman, he was obsessed with

Invested heavily in the research and development of new tanks for the militia.

"Boss, don't worry, those little girls in Europe will be knocked down one by one in front of this big guy, hahaha..." Huffman also burst out laughing. These two dissolute guys were abandoned by their motherland.

In the end, I completely gave up my heart to go back, especially Huffman. It’s amazing how comfortable he has been living in Xiaoqingshan these years. He eats and drinks well every day, and he maintains a relationship with two or three German female staff in the Dongchuan area.

Intimate relationship.

"Let the test begin." Zhang Shusheng nodded and ordered the test to begin. Two domestic scholars and two security personnel climbed into the tank together.

"Boom, boom~" After a burst of violent diesel engine noise, a large cloud of oil smoke spurted out from behind the butt of the tank. Amidst the roar of the engine, the tank first shook, and then the tracks were driven by the driving wheels and rolled over the lawn of the test site.

stand up.

The sound of the engine became louder and louder. The tank's large 400-horsepower diesel engine gradually increased the speed of the tank to 20 kilometers per hour, and rumbled towards the shooting range in the distance.

Zhang Shusheng felt the vibrations coming from the ground while taking the telescope from the security personnel nearby. He saw the Tiger 1 tank smoking all the way towards the shooting range more than a thousand meters away.

"boom!"

The tank fired its first shot facing the mountainside in the direction of the shooting range. Through the telescope, huge explosion smoke could be seen rising from the mountainside.

"Click, click, click..." Although the sound of the heavy machine gun was no longer loud more than a thousand meters away, through high-power telescopes, the tank's parallel machine gun could still be seen firing wildly.

The tank that had finished firing a certain amount of guns and ammunition received an order to return from the on-board wire.

"Zhang, what do you think of this tank? I haven't disappointed you. Large-caliber tank gun, low defensive design, thick armor, fire control equipment, and on-board wiring equipment."

Scheidemann put down the telescope with satisfaction and his heart was full of pride. Although he had lived a happy life in China in the past few years, it was not until the birth of this Tiger that he gained a strong sense of pride and honor.

In his words, he did not necessarily have to belong to Germany, but he must be loyal to the honor. Therefore, he chose to stay in the militia because there would always be tank research work here that made him excited. His goal was to leave his name in the history of tanks.

Zhang Shusheng nodded. The design prototype of this Tiger 1 tank using a 400-horsepower diesel engine is the German Tiger tank more than ten years later. Although the data and technical indicators are much different in all aspects, for example, the engine power is half less.

, but the design concept is correct.

The tank has a low body, a thick chassis, and enhanced climbing performance. It has 4 crew members, a front armor of 60mm, and is equipped with a 75mm tank gun with 40 rounds and a 792mm parallel machine gun. The maximum road speed is 25km/h.

Hour.

Overall, this is a powerful tank. The only drawback is its weight: 28 tons.

If this weight were placed in Europe, with criss-crossing highways, convenient transportation, and vast plains, it would be a trivial matter. However, in today's southwest, except for the county towns with main roads that can be accessed by ordinary roads, other places are completely blank. At most, there are only small roads.

Road. Moreover, there are many paddy fields in the southwest. Under such circumstances, if the 28-ton tank is fighting in the field, it may even sink into the rice field and be unable to climb out.

After the test, Zhang Shusheng called in Scheidemann, a German expert, and several domestic scholars and technicians, "I am very happy to see that everyone has built such a powerful tank. However, we have some practical problems.

But we must pay attention to it. For example, manufacturing is too difficult, and large-scale production will be difficult to achieve at least before 1927. The cost of a single tank is too expensive. If I equip a division, I may go bankrupt tomorrow. In other aspects, the speed is too slow.

Engine manufacturing problems and steel problems are difficult for us to overcome within a few years."

"Zhang, the development of this tank is not easy. You can't just throw it back into the steel-making furnace and recast it with just one sentence." Scheidemann also understands these problems, but it is really difficult for him to resist designing a successful firepower-concentrated tank.

, the allure of an advanced tank that combines speed and defense.[

"This kind of tank can be equipped in small quantities. I also organized discussions with other experts and came up with another tank plan that is more suitable for the current militia groups."

Zhang Shusheng took out a drawing and handed it to them to see.

"Light tank?" Scheidemann asked doubtfully.

Zhang Shusheng: "Yes, I hope you can complete this Tiger 2 light tank as soon as possible. The Tiger 1 medium tank will only be equipped with a small number of elite troops, while the Tiger 2 tank will be equipped with more."
Chapter completed!
