Super Military Scientist

The ninth chapter is a genius and an all-rounder

Zhao Zhongyao took the remote control and commanded the model airplane of his own design, and started flying in the sky. Liu Changyun really didn't expect that the model airplane designed by Zhao Zhongyao could really fly in the sky.

Zhao Zhongyao used the remote control to remotely control his own model airplane, doing various difficult movements in the sky. Liu Changyun looked a little dazzled. He really didn't expect that this model airplane designed by Zhao Zhongyao could not only fly, but also make some difficult movements in the air. The performance of this model airplane in the air is very free and easy, and people will feel that the performance of this model airplane is very good. It is not easy to design such a model airplane. Moreover, it is possible to design such an advanced airplane model aircraft only with a certain knowledge of aircraft design.

"Zhongyao, the model aircraft that you developed is really good. How did you develop it, what was it made of, it looks like it is similar to a real airplane." Liu Changyun is now a little curious, he Said Zhao Zhongyao, who was still looking at the remote control airplane.

"Is this! This airplane is made of a kind of plastic steel." Zhao Zhongyao looked at Liu Changyun and said. "Oh, a kind of plastic steel, is that steel?" Liu Changyun looked at him with a little puzzled after hearing what Zhao Zhongyao said.

"Since it is plastic steel, of course it is not real steel. It is just a strong plastic." Zhao Zhongyao said again.

"That's the case, then can you tell me more about how you developed your model aircraft now. I want to know about this now." Liu Changyun looked at Zhao Zhongyao and said.

"Okay, let me land the plane on the ground first." Zhao Zhongyao said, using the remote control again, the plane landed smoothly from the sky to the ground.

"Zhongyao, the model aircraft you designed can fly fast and smoothly. I really don't know how you designed it. Are you very experienced in developing model aircraft?"

Liu Changyun now wants to know how Zhao Zhongyao developed such an advanced aircraft model fighter. After all, he had never seen such a model airplane before.

"Leader, you want to know how the model airplane was developed!" Zhao Zhongyao put the remote control on the wing of the model airplane and said while looking at Liu Changyun.

"Yes, I just want to know the basics of developing a model airplane. When I was a child, I was very excited about the model airplane and wanted to develop a model airplane myself, but I don't have the ability to do this. As soon as you have developed this model aircraft, I want to know this knowledge."

When Liu Changyun was a child, he was very interested in model airplanes. But when he was a child, his family was very poor, and the country's technology was underdeveloped. There is not much progress in the development of aircraft. The country’s large aircraft are all imported from abroad. Some high-tech model airplanes are also imported from abroad. Most people simply cannot afford such a model airplane. Liu Changyun has only seen these high-tech model airplanes on TV, but he has never seen them in reality.

Today, it was the first time that he really saw a model airplane. And it is a very special model airplane. When he saw this special model aircraft developed by Zhao Zhongyao, he also wanted to know how Zhao Zhongyao developed such a model aircraft. Liu Changyun also wanted to learn from Zhao Zhongyao.

"Okay, let's go to your office and talk about it slowly! There are also a lot of basic knowledge for developing model airplanes. This is not something that can be said clearly in a few words." Zhao Zhongyao looked at Liu Changyun and said.

"Okay, of course, just go to my office!" Liu Changyun listened to Zhao Zhongyao's words, and naturally readily agreed.

After Zhao Zhongyao finished speaking, he looked at Liu Tianming and said, "Director Liu, can you help me move this model airplane to the car!"

After hearing what Zhao Zhongyao said, Liu Tianming smiled and said: "Why can't I, here, I won't help you, who will help you." After finishing speaking, he and Zhao Zhongyao put this model aircraft together again. Carried into the car.

The three of them went upstairs again and came to Liu Changyun's office.

After arriving at the office, Liu Changyun gave Zhao Zhongyao and Liu Tianming to the sofa.

Liu Changyun himself sat on the opposite sofa. He now looked at Zhao Zhongyao and said, "Zhongyao, you can now tell me some knowledge about the development of model aircraft. I am really interested in these things.

After listening to Liu Changyun's words, Zhao Zhongyao smiled and said: "Okay, then I will tell you some knowledge about the development of model aircraft that I know myself!"

After finishing talking, Zhao Zhongyao paused, thought for a while, then looked at Liu Changyun and said, "Model airplanes are mainly composed of airplane model aircraft and airplane remote control. Let’s talk about the airplane remote control first. Wait a moment. , Let’s talk about model airplanes."

After speaking, Zhao Zhongyao thought about it again, and then went on to say: "Common wireless remote control mainly includes infrared remote control and 2.4G remote control according to the different technologies used. Infrared remote control has the characteristics of narrow direction range and short distance, so model aircraft remote control Basically, all devices use 2.4G wireless remote control. So what is the difference? First of all, we need to make a brief introduction to 2.4GHz wireless technology and standards.

2.4GHz wireless technology has now become the mainstream transmission technology for wireless products. The so-called 2.4GHz refers to a working frequency range of 2400M-2483M, this frequency band is free of application for use worldwide.

But because of the different scope of application. The 2.4G frequency is also used as the carrier, and the communication methods derived from different communication protocols will be very different. Just in the amount of data transmitted, there is a difference from 1M per second to 100M per second.

The model airplane remote control uses a 2.4GHzISM frequency band wireless protocol, and the remote control protocol is called the 2.4GHz wireless communication protocol.

2.4G wireless communication module works in the world without applying for 2.4GHzISM channel, the frequency range is 2400MHz-2483MHz. Realize the automatic frequency sweep function when starting up, with a total of 50 working channels. Basically, model airplane remote controllers on the market use 2.4G wireless communication modules, and a receiver will be configured for the remote controller. The remote control (transmitter) and the receiver need to be paired for use, and different manufacturers are generally not compatible because the transceiver chips and protocols used may be different.

The remote control has the difference between domestic and imported. The difference between domestic remote control and imported remote control lies in the gap in radio technology. On the other hand, there are too few domestic research and development institutions and they have not undergone long-term product testing.

Domestic remote controllers use relatively cheap electronic components, so the cost is relatively low, especially the receiver, receiver chips, good receivers are all imported chips, so they are very stable, the programming is better, and the cheaper receiver chips are better. Cheap, so it's easy to get into trouble.

A very simple example, the potentiometer on the remote control, domestic equipment used domestically produced potentiometers generally have a life of 100,000 to 300,000 times, and the potentiometer of imported equipment can reach 1 million times, which directly affects the life of the remote control.

It is generally believed that the JR remote control is the best in terms of the workmanship of the remote control, and the wiring layout is very good, especially at present, only the JR remote control is equipped with a fuse. What's more important is that all JR remote controls are manufactured abroad, and the quality is guaranteed.

So the price of the remote control is what you get. The expensive imported remote control naturally has its expensive reason. The cheap domestic remote control is also cheap.

Nowadays, there are more and more domestic remote control manufacturers, and the price concessions make the threshold of model airplanes lower and lower, so we can reasonably choose our own remote control according to our economic strength. "

After Zhao Zhongyao said the knowledge, he looked at Liu Changyun and said, "How about, Minister Liu, you can still understand the knowledge you told me!"

After Liu Changyun listened to Zhao Zhongyao's knowledge, he felt a little bit understandable. However, in front of Zhao Zhongyao, he was too embarrassed to say that he did not understand at all. After all, he is a leader and also has a college degree. How can he speak and understand this knowledge.

Thinking of this, Liu Changyun looked at Zhao Zhongyao and said, "Well! I can almost understand it. It's just that you just talked about the knowledge of the remote control. Can you tell me more about how to conduct remote control."

After hearing what Liu Changyun said, Zhao Zhongyao thought for a while and said, "Okay, let me talk about the flight controller."

After that, Zhao Zhongyao began to teach Liu Changyun again: "Flight control is the soul of multi-rotor aircraft. So what is flight control? Flight control is the electronic control part of the aircraft, which is called the flight controller in full. The flight control mainly includes Main control processor MCU and inertial navigation module (sensor part).

Compared with helicopters and other aircraft models, the most complicated part of quadcopter is the electronic part. It can be compared with fixed wing and helicopter. In conventional fixed-wing aircraft models, gyroscopes are not commonly used devices. Relatively difficult to control the straight upgrade model, if the automatic stabilization system is not used, the gyroscope is only used for the tail lock. A four-axis aircraft must be equipped with a gyroscope, which is the most basic requirement, otherwise it will not be able to fly, let alone flying stably. Not only does it have to exist, it has to have all three dimensions, which is determined by the mechanical structure and power composition characteristics of the quadcopter. On this basis, supplemented by a 3-axis acceleration sensor, these 6 degrees of freedom constitute the basic part of flight attitude stability and the key core part of the inertial navigation module, referred to as IMU. The attitude sensing in flight depends on this IMU, which shows that it is the core component of the entire model.

The IMU senses the attitude of the aircraft in the air and sends the data to the main control processor MCU. The main control processor MCU will control the stable operation of the aircraft through the flight algorithm according to the instructions of the user's operation and the IMU data. Since there is a large amount of data to be calculated, and real-time control is required, the performance of the MCU also determines whether the aircraft can fly sufficiently stable and flexible. "

Zhao Zhongyao gave Liu Changyun some knowledge about the main controller of the model aircraft. After Liu Changyun listened, he felt that he really gained a lot of knowledge. At this time, he really admired Zhao Zhongyao. Originally, he thought, Zhao Zhongyao might not know much about aircraft model knowledge. After all, he is just a military industry expert, not an expert on aircraft.

However, what Zhao Zhongyao told Liu Changyun about model aircraft knowledge was something Liu Changyun had never heard of.

"Zhongyao, what you said is so good, you are really knowledgeable!" Liu Changyun listened to Zhao Zhongyao's knowledge of aircraft model aircraft, and his knowledge of Zhao Zhongyao was even better. Admire it.

"Hey! I'm also embracing myself! In order to develop this model aircraft, I also learned a lot of knowledge about aircraft model aircraft." Zhao Zhongyao looked at Liu Changyun and said.

Originally, before Zhao Zhongyao, when he was in the "Zhuhai Aviation Academy", in order to study model aircraft, he also learned a lot of knowledge about model aircraft. After all, a qualified aircraft designer must learn about aircraft model aircraft. It is impossible to develop any kind of aircraft at once. First of all, it is necessary to study a model aircraft, test the performance of this aircraft first, and see what advantages and disadvantages this aircraft has. Only constantly modify the deficiency. Only when it is developed into a truly large aircraft, there will be fewer or no problems.

"You are so good at embracing the Buddha, so if you study this knowledge seriously, then you should be so good." Liu Changyun looked at Zhao Zhongyao and said.

Without waiting for Zhao Zhongyao to say anything, Liu Tianming interrupted at this moment and said: "Minister Liu, is Zhao Zhongyao an all-rounder? There is nothing he doesn't know. I have been with him for two or three years. In my opinion, the knowledge that Zhao Zhongyao knows is far above us. Let alone laymen like us. Even some military industry experts do not know as much as Zhao Zhongyao. Liu Tianming can be considered to have deep knowledge. I feel it. He and Zhao Zhongyao have been together for two or three years. No matter what kind of advanced weapons they are researching, as long as Zhao Zhongyao develops them, it will definitely be faster and more advanced than others.

"No, the AK-47 assault rifle developed by Zhao Zhongyao before is very advanced. It can now be said that it occupies half of the sales of light weapons in the entire international market. It has created a miracle in the sales of light weapons in history.

Now that this model aircraft developed by Zhao Zhongyao is so advanced, I really feel strange. I don't understand Zhao Zhongyao, how did you do this, do your head look different from ours. "

Liu Changyun listened to Liu Tianming's words and then recalled what he had heard about Zhao Zhongyao in the past two years. He also felt that Zhao Zhongyao was not only a genius, but also an all-rounder. There is nothing he doesn't understand.
