Super Military Scientist

The first thousand and fifteenth chapter prototype was successfully developed

"Director Liu, do you think this is appropriate! Our ‘Skunk Factory’, can ordinary workers come in and work!" Zhao Zhongyao looked at Liu Tianming again and said.

After hearing what Zhao Zhongyao said, Liu Tianming looked at him and said, "Well, what you said makes sense. Then you said, how do we recruit some skilled workers to complete our major production tasks."

"You don't have to worry about Director Liu. I will select some excellent workers from some military bases of our general equipment. Let them help us complete the production task of this prototype." Zhao Zhongyao said again.

"Okay, I'll leave this to you. Hurry up and find some skilled workers!" Liu Tianming also looked at Zhao Zhongyao happily and said.

In this way, Zhao Zhongyao found some more skilled workers, and Liu Tianming applied for some prototype research funds from Liu Changyun, and began to study the prototype of this stealth fighter.

Originally, it was very difficult to study a new type of fighter. It's like crossing the river by feeling the stones. There is no way to go. Everything is moving forward in groping.

But with a master like Zhao Zhongyao, it's different. He can avoid many detours in the development process.

In addition, the skilled workers that Zhao Zhongyao found were all very high-quality skilled workers, like Zhao Gang and Li Nansong, who had many years of technical experience in machinery manufacturing.

In this case, Zhao Zhongyao's time to develop this prototype was greatly shortened. Originally, under normal circumstances, it would only take a year to study a prototype. But in Zhao Zhongyao, it took only two months to develop and produce this prototype.

When this prototype was produced, Zhao Zhongyao called Liu Tianming and Liu Changyun into their ‘Skunk Factory’ together. Let them both take a look at the prototype he designed and developed.

Liu Tianming and Liu Changyun looked at the prototype of the stealth fighter developed by Zhao Zhongyao and felt that this prototype was well studied. It's exactly the same as a real airplane. It feels like this is not a prototype, but a real fighter.

"Zhongyao, how did you develop it? You developed this prototype so quickly. Your work efficiency is really amazing!" Liu Tianming looked at the prototype in front of him. I couldn't help but praise Zhao Zhongyao.

"Yeah! Zhongyao, your work efficiency is really amazing! This is an airplane, why did you produce it so quickly?" Liu Changyun also looked at Zhao Zhongyao very surprised and said.

"Minister Liu, when we do anything, we must have a plan. As long as we have a thorough plan and proceed gradually according to the plan, it is enough. Sometimes, we do things very slowly because we are doing things. There is no careful plan for such a thing. When doing this, many detours will be taken and a lot of precious time will be wasted."

For Zhao Zhongyao, he did not know how to explain why he developed this prototype so quickly. He can only say some seemingly important reasons, but this reason is not an important reason why he developed this prototype so quickly.

After Liu Tianming and Liu Changyun heard what Zhao Zhongyao said, they felt very reasonable, and even believed it. There is no feeling, Zhao Zhongyao is just talking nonsense!

"Zhongyao, the prototype has been developed. What's the next step? Is it the beginning of the test flight!" Liu Changyun can be said to be an outsider in the development of aircraft. He saw that this prototype had been developed, and he wondered if he could start the test flight now.

After listening to Liu Changyun’s words, Zhao Zhongyao smiled again and said, "Minister Liu, things are not that simple. An airplane is no better than a car. After the new car is developed, it can be tested immediately. After it is developed, it cannot be tested in the air immediately. Because it is very dangerous to do so. If you want to make an airplane fly into the sky, the first thing is to let the airplane fly on the ground for a period of time before it can fly into the sky. Go!"

"Oh, this plane needs to'fly' on the ground first! What's the matter, how can the plane fly on the ground. If the altitude is too low, won't it also affect flight safety!" Liu Changyun listened to Zhao Zhong In the case of Haruka, he asked another layman's question.

"Minister Liu, I'm talking about'flying' on the ground. It is not a real flight, but a flight simulation experiment in a wind tunnel. It is a kind of simulated flight, not a real flight." Zhao Zhongyao looked again Said Liu Changyun.

"Oh, I see. The wind tunnel laboratory you built before was designed to allow airplanes to fly on the ground." Liu Changyun heard Zhao Zhongyao's words and seemed to think of some problems. So, Said again.

"Of course, the wind tunnel laboratory we developed is to allow prototypes to fly on the ground. After any new aircraft is developed, a simulated high-altitude flight training must be carried out in the wind tunnel. Only in In the wind tunnel, after a simulated flight, it is possible to fly to real high altitude. If you don't do this wind tunnel experiment, but let the plane fly directly into the sky, wouldn't it be very dangerous!"

Zhao Zhongyao saw that Liu Changyun didn't know much about how to develop a new type of aircraft, so he explained to Liu Changyun in detail how the new aircraft was developed, a problem that ordinary people are not familiar with.

"Zhongyao, so to speak, we can immediately let this prototype enter the wind tunnel experiment for simulated flight." Liu Tianming said while looking at Zhao Zhongyao again.

"Of course this is the case. However, before entering the wind tunnel laboratory, I have to fly a full inspection of this aircraft. If there is no problem, I will do another static experiment. If there is no problem, If so, you can drive to the wind tunnel laboratory for simulated flight training." Zhao Zhongyao looked at Liu Tianming and Liu Changyun and said.

"Oh, I have to do a static experiment. What is a static experiment." Liu Changyun is a layman in aircraft manufacturing. When he heard Zhao Zhongyao's words, he felt that this'static experiment' was a new term for him. , He wants to know about this new term.

After hearing what Liu Tianming said, Zhao Zhongyao smiled and said, "This term is a very professional term. If you want to know, I can explain it to you."

"Okay, tell me!" Liu Tianming looked at Zhao Zhongyao, wanting to hear how he explained.

"Static test is one of the contents of structural test. It is an important means to verify the correctness of aircraft structure strength and static analysis by observing and studying the strength, stiffness, stress and deformation distribution of aircraft structure or components under static load. The loading system for the full-scale static test of the structure is more complicated. Before the 1940s, during the static test, the aircraft was placed upside down, and lead or sand particles were used in the bag to simulate the wing distribution load; the iron block was suspended on the rope. The method of simulating concentrated load is simple. Later, it will be loaded with electromechanical afterburners or hydraulic actuators and jacks. Since the 1940s, full-scale structural static tests have been loaded through a lever system, and a multi-point coordinated loading system is used to ensure that each The loader can be loaded according to a predetermined ratio, and it can be automatically unloaded when the structure is damaged to avoid the continued expansion of the damaged part. In the 1970s and 1980s, the static test has adopted an electronic computer-controlled electro-hydraulic servo system to automatically close the loop to coordinate the loading system. Hundreds of loaders, hundreds of loading points, hundreds of measurement channels, thousands of strain gauges, and electronic computers for data acquisition and processing.

To carry out structural static experiments, it is necessary to design and manufacture structural test pieces, supporting systems and loading devices, and then install them and debug them together with instruments for measuring displacement, strain and load. After debugging, the experiment can be carried out according to the following two steps: ①Pre-experiment stage. Slowly add a small load step by step according to a certain procedure, observe and monitor the displacement and strain measurement points, find out the basic trend of structural bearing and deformation, and inspect the test pieces, support systems, loading devices and measuring equipment. reliability. ②Formal test stage. Often take 5-10% of the expected load as the initial load, and measure the initial stress, strain and displacement. Then load it step by step, uniformly and slowly according to a certain procedure, and measure and record the data of each strain measurement point, displacement measurement point and load measurement point one by one. At the same time, carefully observe the test piece until it reaches a predetermined load or a predetermined experimental state. Formal experiments sometimes need to be repeated many times. Finally, the test piece was inspected, its residual deformation and damage were carefully inspected, and the recorded displacement, strain and load data were processed and error analyzed to draw scientific experimental conclusions. "

Zhao Zhongyao told Liu Tianming what he knew about the static experiment. After Liu Tianming listened, he felt that he had benefited a lot. He looked at Zhao Zhongyao and said, "Zhongyao, how do you know everything? I seem to have never heard of this knowledge."

"Director Liu, you are a leader. How did you learn these professional knowledge? I am a technology company. Of course it is different. In order to design this stealth fighter, I learned a lot of knowledge about aircraft manufacturing."

In fact, the knowledge Zhao Zhongyao said was something he had learned before his death. Although he was a physicist during his lifetime. But the knowledge of these static experiments also belongs to the category of physics. Zhao Zhongyao also dabbled in this knowledge.

"Well, Zhongyao, if you have this knowledge, can you carry out static experiments? If the static experiments are successful, then can you carry out flight experiments on this prototype in a wind tunnel?"

Liu Tianming heard what Zhao Zhongyao said about static experiments, and he imagined what they might do next.

"Yes, we have to do a static experiment on this prototype first. If the structure of the aircraft is completely reasonable and meets the flight requirements, we can put the aircraft in the wind tunnel for flight experiments." Zhao Zhong Yao looked at Liu Tianming again and said.

"Okay, then you quickly do static experiments! We don't have much time. It is very difficult to produce the first new fighter aircraft within a year."

Liu Changyun didn't speak a moment ago, but now he heard what Zhao Zhongyao and Liu Tianming said, and he said something in agreement.

"Yes, Minister Liu is right. We still have to seize the time to produce the first true stealth fighter. We must produce our new fighter before the next'Bamboo Sea Air Show'. This is the air show. At that time, we can let our fighters show off at the'Bamboo Sea Air Show'." Zhao Zhongyao said again.

"Okay, then we won't bother you anymore. You can work quickly!" After Liu Changyun finished speaking, he looked at Liu Tianming and said, "Tianming, then let's go! Let Zhongyao and the others work hard!"

"Okay, we won't bother you. You guys hurry up and work hard!" After Liu Tianming finished speaking, he came out of the experimental workshop of the new fighter plane with Liu Changyun.

Zhao Zhongyao sent the two leaders out of the gate of the factory and then returned to the aircraft experimental workshop. Look at the prototype that I developed successfully. Zhao Zhongyao was also very happy. However, he knew that this prototype could not fly to the sky. It's just an experimental machine for flying experiments on the ground.

If they want their fighters to fly into the sky, they have to develop a new type of fighter. Only then can they be regarded as successfully developing the first new fighter.

Next, Zhao Zhongyao led some of the engineers and technicians under him to conduct a series of static load-bearing experiments on this prototype.

Of course, before conducting such an experiment, Zhao Zhongyao was also very confident. He knew that there would be no problems with the prototype he developed. Because the prototype he developed uses some of the most advanced aircraft materials. Some materials, which may not even be available abroad, were developed by Zhao Zhongyao himself.

For a scientist who has known some advanced aircraft manufacturing materials a long time ago, if he is building a fighter that he has known for a long time, he can definitely avoid many detours. And, it can be successful once.

In this way, Zhao Zhongyao and his scientific and technical personnel conducted a series of static experiments on this prototype. The results of the experiment were very satisfactory to everyone. Because all the experimental data of this prototype machine are qualified. Fully achieved the expected imagination. This made Zhao Zhongyao and the scientific and technical personnel under his staff very happy.
