When Zhang Chun came back, he saw not only troubles, but also some interesting things.

Zhang Chun watched a science and education movie called "Forest" on the square of Xinmin University.

The story is about a little boy and a little tiger playing in the forest, looking for honey. However, in the process of searching, the various forms and evolutionary processes of the forest are fully revealed.

It's a pity that the film is black and white and silent. The narration has a female student from the Academy of Arts who dubbed live during the broadcast.

The film shooting equipment and playback equipment are very backward, and Liang Sishun got it back from France through Lin Changmin.

Originally, the film was used as a teaching material for the Forestry College, but I didn't expect that the little boy and the little tiger were very popular with the students and became an entertainment thing.

Zhang Chun was not satisfied with the quality of the film. However, the way in which movies are used for science and education is affirmed. Because ordinary people may not be able to understand the theories in books, but by covering them up by movies, they can quickly convince even illiterate peasants.

When Zhang Chun once attended a lecture at the Institute of Electronics, he praised this method of science and education, and said that film technology could be further improved, and light and shadow could be directly converted into electronic data, recorded on a certain medium, and then re-read and restored to light and shadow, which was better than film. In addition to the image, the electronic recording of sound is easier to achieve, and the combination of the two is the real film.

Cinema is actually an information recording technology, at least capable of filming biological activities under an optical microscope. It's very useful to magnify very subtle light and shadow under the microscope for people to study. This magnification is much greater than a person's eyesight. Electrical signals can also be visualized in a certain way. For example, the phenomenon of recording the discharge of atoms, but this change is not artistic.

Because of the great progress made in semiconductor and transistor research, the Institute of Electronics put into practice Einstein's laser theory in 1917. They made all sorts of rays. Because of this technology, the Institute of Electronics has set up a physics institute. Study various microscopic physical phenomena in a cave at the Green Lake Research Institute.

They are worried about how to detect, and Zhang Chun's theory of electron microscopy and information recording and analysis has given them a window. The Institute of Physics and the Institute of Electronics immediately jointly established the Institute of Nanotechnology, which means to solve this problem with nano-level information technology.

Liang Sishun did not know that the Institute of Electronics would create a new set of shooting and information storage technologies by improving the optical microscope into an electron microscope.

A lot of the techniques seem difficult, but they get to the point. It's simple. The key is manufacturing technology, and nano needs a complete set of precision instrument manufacturing technology to support. So Nano is doing ant moving work again.

Lin Changmin was entrusted by Zhang Chun to prepare to go to Germany to meet Einstein. Let's see if we can get him to China, even if it's to trick him into China. Zhang Chun's plan was not to leave when he came. Zhang Chun knows a lot of advanced theories, but he can't do practical work.

The temptation given by Zhang Chun was to give Einstein the New People's Science Award for his theory of relativity. Tell Einstein, though. The theory of relativity was not first proposed by Einstein. There was a discussion in ancient China, and Zhang Chun also proposed it in a lecture at Xinmin University, but Einstein proved it with a theory, and the Institute of Physics of Xinmin University proved it with experiments. Because Xinmin Journal is an internal journal of Xinmin University, it is not distributed to the public, and there is no German or English edition. What Lin Changmin brought over was the publication of articles on rays by the Institute of Physics, as well as articles on the principles of radar and radio telescopes.

These principles are actually quite simple. However, the most powerful thing of Xinmin Research Institute is precision manufacturing and miniaturization research. This is far ahead of its time. It is not comparable to Germany and the United States. Of course, it is also the result of Zhang Chun's abandonment of many research directions in the American and German military industries, such as artillery giant ships.

Green Lake Research Institute.

Hidden in a cave beneath the highest peak. A three-stage turbine fan was installed. Inside, a model airplane is doing wind tunnel experiments, and the amount of force generated by the movement of each aileron on the aircraft is recorded. At the same time, the reliability of the hydraulic system is also tested.

The aerodynamic layout of the aircraft is completely the full-lift layout of the canard wing of later generations. If there is not a fixed force measuring device. A gust of wind can blow this aluminum model away.

For this model, the flight controller took much more time to convert than the electronics.

"Light fighters are fine, just cannons first. Do not load bombs. Later, when the plane was equipped with radar and missiles, it could be regarded as a real success. Now it's enough to experiment with manufacturing technology and engine technology, and have a little combat effectiveness. Strive to be able to test flights next year. Pilot training can't just be simulated in a wind tunnel, that's not real. ”

Zhang Chun watched the airplane experiment from behind thick glass.

Wang Zhu and Zeng Yijing were aircraft designers that Lin Changmin did everything possible to dig from Sun Yat-sen's Republic of China Naval Aircraft Engineering Office. However, when the two of them came here, they found that the design and manufacture of aircraft here had exceeded the knowledge of the two people, and the leader of the design was actually the "warlord leader" Zhang Chun, although he just came to talk casually, but the aerodynamic theory proposed was very perfect.

The aircraft of the flight control station was developed from a rocket and was completely different from the foreign design concept. The turbojet engines they use are very well built. The engineers here are very professional, the only thing that doesn't work is that they don't have flying experience.

When Lin Changmin found them, he just said that the two of them would be test pilots, and the two of them were very unconvinced at first. But looking at it now, you can only be a pilot.

The two followed Zhang Chun to Jingmen. There is a train from Luhu to Zhongxiang, but Zhongxiang still uses a bus to get to Huji.

The entire road is hidden in the forest, and there is basically nothing to see except the trees.

Huji has renovated a runway, and a hangar and huge aircraft manufacturing workshop are being built. The equipment is being installed and the workers are being trained.

Of course, even more huge are the surrounding spare parts factories.

"The tire factory is in Qianjiang, and it doesn't meet the design requirements yet. The production plant of the wing is ready to be built in the aluminum mine, and the Fairy Machine-Building Plant is producing a large water press for integral casting and forging, and in the second half of the year it should be possible to conduct process research. From a purely technical point of view, there is no problem. The foundry has been engaged in heat treatment technology for more than ten years, and the material treatment of some special parts is entrusted to them. The design of this aircraft has a good lift and a good mastery, but if something happens to the engine, there is no big problem. Now the key is the electronic control and hydraulic system. If these two systems are not good, you will not be able to come back. Our aircraft engines determine that it is very fast, far faster than propeller aircraft. So in order to ensure the safety of both of them, a parachute ejection device was designed. As a result, the completion of the aircraft design is expected to be postponed, and next year's test flight is only ideal, not necessarily completed. Then there is the fact that the future combat effectiveness of this aircraft comes from missiles and radars, both of which are now very problematic. I can't estimate the time of equipping either. ”

In the past two years, a designer named Xie Wanting has gradually emerged, and this designer who is less than 30 years old has been immersed in the rocket and ammunition station since he was more than ten years old. Now he is the director of the flight control office.

The director of the power institute is called Teng Yusong, who is one year younger than Xie Wanting. These two people and Qin Deming of the Institute of Electronics became the troika of aircraft manufacturing research.

"It's fast and flexible, even if you only have a cannon, you can win with confidence. It's just that it's a brand new plane, and we can only do our best to fly it. Wang Zhu is still looking forward to this plane.

"Not only that, but the two will still be involved in the design of the aircraft in the future, and no one knows the aircraft better than the test pilots. In addition, the two of them should familiarize themselves with the maintenance and operation of this type of aircraft as soon as possible, write teaching materials, and train pilots in the future. And propose improvement suggestions for manufacturing plants. Xie Wanting looked at the skilled workers who were installing the equipment and said.

He doesn't care whether Zhang Chun is present or not, whether he is authoritative or not. The request was made directly.

"Yes". Wang Zhu and Zeng Yijing replied at the same time.

Zhang Chun is actually quite proud of the growth of these people, you know, this is also the top in the world. He smiled and said, "The Air Force will be a powerful branch of the military. But be careful. The army's missiles can shoot you down, and radar and missiles are your nemesis. The sky of the future is the world of missiles. Your goal is higher skies, skies where you have plenty of time to react and dodge. And most likely space. Because I am confident that the speed of the missile will be increased to several times the speed of sound. Airplanes are more complex than missiles, and with manned pilots, they will never be able to catch up with the pace of missile development. ”

"Then why develop airplanes?" Wang Zhu had this concern after seeing the introduction of the missile, but he liked airplanes and refused to say it.

"Because of the radar. Due to the curvature of the earth. Higher in the sky, pilots have the opportunity to avoid missiles with the help of detection equipment such as radar. And the aircraft can also be equipped with missiles for self-protection. Qin Deming squinted his eyes, as if to say a dream: "Radar also has defects, at low altitudes, ultra-low altitudes, ground radars have blind spots." It takes time for the radar to detect the target and for the missile to react to launch. So the plane is not without a chance to play. Our aircraft are designed with both of these goals in mind.
