The Aircraft Research Institute is located in Wuzhuang forty miles away from Lantian County. The terrain is open and flat, and the wealthy Yi Zhengde bought all the tens of thousands of hectares of land around him and left it deserted in one breath.

The airport is not big, and only a simple cement runway has been built. The aircraft really does not have high requirements for the runway. The few aircraft currently used for experiments only need a piece of grass or gentle slope to take off and land.

The newly moved aircraft research institute, the separated helicopter research institute is not far from the airport, and behind it is a factory building, a large area of ​​newly built two-story red brick houses look very eye-catching from a distance.

Although all the local people in Wuzhuang have moved, the continuous recruitment of scientific researchers, newly recruited college students, technical workers, a large number of troops and engineers and supporting affiliated institutions have quickly made Wuzhuang prosperous and lively.

Yi Zhizu arrived in Wuzhuang and moved directly into the only guesthouse. After taking the train for two days, he was really tired. After taking a hot shower, he slept again and then recovered. When he entered the living room, he saw Yi Zhengde and Zhao Liewen quietly reading newspapers. He couldn't help but smile and "Go out and have a walk."

Wuzhuang is not big, with only one street that is only 200 meters long, but there are all banks, posts, telecommunications, newspapers and kiosks, bookstores, shops, teahouses, restaurants, barber shops, snack shops, etc. Perhaps because they have already gotten off work, it looks a bit lively and there are many pedestrians on the street.

The three of them walked all the way, walked around and entered a teahouse casually. After asking for a private room and called tea, Yi Zhengde whispered: "All the shops are invested and built by us, and there are no outsiders in the entire Wuzhuang."

After hearing this, Zhao Liewen couldn't help but smile and said, "This has really become a paradise."

"It's very appropriate to have a paradise." Yi Zhizu said: "It's remote, but it has tap water, electricity, heating, telegraphs, planes and cars. It's all about daily needs, and it's basically isolated from the outside world. Isn't it a paradise?"

As he said that, he said with great certainty: "Okay, very good! He was thoughtful. Only in this way can they take root here and do research steadily."

After a pause, he continued: "In addition, parks and sports venues must be built to provide them with leisure and exercise venues. You can also organize art troupes from the troops to come and perform. In addition, you must also consider building schools to avoid their worries."

Yi Zhengde smiled and said, "Didn't it meant that this is just temporary?"

"This time, at a short time, at a short time, at a long time, at a twenty or even thirty years." Yi Zhizu took a sip of tea and said slowly: "The appearance of the plane in Shanghai has caused a sensation in the world, but it will take a long time to put the plane into the military field.

Judging from the information currently available, major powers in the world are actively developing aircraft, but they do not have a military background. After all, no one has realized the great value of aircraft in the military.

As for helicopters, because of the reasons why our country is confidential, countries around the world do not have the idea of ​​helicopters. If there is no big war, the confidentiality time for helicopters may continue to be extended."

Yi Zhengde said in confusion: "Since the aircraft has great military value, why didn't my father keep it secret at the beginning?"

"Can it be kept secret?" Yi Zhizu smiled and said, "How can so many foreign scientific researchers in your aircraft research institute keep secrets? Besides, I didn't expect that the research progress of aircraft would be so fast.

Another thing is that when a plane flies in the sky, there are many people who can see it, and it is difficult to keep it completely confidential. Although you are in Lantian, who do not know about the planes that can fly in the sky now?"

Yi Zhengdedao: "Isn't Xi'an not open to the public? Just control the newspaper..."

"As such a novelty, it will inevitably be mentioned in private messages. Can you control newspapers and private messages?" Yi Zhizu said: "Although Xi'an is not open to the public, it is the largest industrial base in the northwest after all, and it should not be without the eyes and ears of various countries. We are collecting foreign intelligence, and foreign countries are also trying every means to collect our country's intelligence."

After a pause, he continued: "This is just the first aviation base in our country. Once the conditions are ripe, we will build a second and third aviation base in other more remote and secret places."

The Helicopter Research Institute covers a vast area and has newly transplanted many trees. The environment is quite elegant. The first thing to inspect is the helicopter power department. There is a huge helicopter engine in the tall workshop. After the machine is started, the propeller and tail rotor begin to rotate quickly.

The half-moon shape surrounding Yishizu's scientific researchers showed unconcealed enthusiasm in their eyes, not only because Yishizu proposed the helicopter's idea, but also because Yishizu directly drew a simple sketch of the helicopter, especially the tail rotor of the helicopter.

A small tail rotor is really a wonderful idea, because the tail rotor has a great effect, which not only solves the problem of helicopter spinning, but also solves the problem of helicopter control yaw and pitch, greatly shortens the research time and directly gives the helicopter great practical value.

Yi Zhengde introduced: "This is the initial power of the helicopter, using a four-cylinder internal combustion engine, with 30 horsepower." After a pause, he continued: "The engine shakes very much and the control is complicated. If an engine with more power is used, the shake will be stronger..."

Not only is it shaking, but it is also noise. It is easy to estimate that helicopters in later generations should have used turbine engines, but he knows nothing about this thing and doesn't know where to start if he wants to mention it.

Just shake. It’s not too late to replace the turbo engine in the future. What he needs now is that helicopters have certain practical combat capabilities. He remembers it very clearly that during World War II, the engine of the fighter could reach 1,000,2,000 horsepower, but it was only twelve-cylinders.

He reached out and pressed the signal to turn off the engine. After waiting for quietness, he turned around and glanced at the middle man and said aloud: "Whether it is an airplane or a helicopter, the most important thing is power. If the airplane is compared to humans, the engine is the heart of the airplane!

The engine plays a decisive role in how the aircraft can develop! The Aircraft Research Institute, the core of the airline is not something else, but the engine!

The current internal combustion engine is only in its infancy, and the four-cylinder engine still has a lot of room for improvement. It can develop five-cylinder, six-cylinder, nine-cylinder, and twelve-cylinder engines. The engine's horsepower can also exceed your imagination!

Here, I can tell you clearly that you are engaged in the greatest, most promising industry of mankind, full of infinite beauty and possibility. This is an industry and opportunity that can allow you to be recorded in the history of human civilization, the world and the history of our country's aerospace. It is also a scientific research project that can make you strive for for your whole life!”

Without applause, everyone was shocked by the twelve-cylinder engine he proposed. Everyone knew that this big shopkeeper of Yuanqi would never speak nonsense!

"Remember one sentence: as long as the power is strong, the bricks can fly into the sky!" Yi Zhizu said and walked out of the workshop quickly.

A single-engine aircraft with a full metal shell painted silver-white paint was quietly parked on the airport simple runway. Compared with the aircraft that first tested in Shanghai, the aircraft has undergone great changes. Although it is still two layers of wings, it has been significantly reduced. At first glance, the proportion of the entire aircraft is much coordinated.

Yi Zhizu circled the plane a few times, knocked and touched it, and finally came to the propeller on the nose. In his eyes, this all-metal winged aircraft was still simple, but it was exactly the same as the plane he remembered before the battle.

Huang Dianyuan looked disbelief and asked softly: "Can this guy fly into the sky?"

Yi Zhizu smiled and said, "Try it." He pulled him out of the runway.

Tang Chutian, a pilot who had been waiting by the plane for a long time, quickly stepped forward and turned the propeller, then boarded the plane, gestured and closed the cabin hood. After the plane quickly gambled on the runway for a distance, the nose of the plane lifted and instantly left the runway and flew into the sky.

Seeing this scene, Huang Dianyuan opened his mouth wide for a long time and looked at the plane gradually moving away, Yi Zhizu asked slowly, "What is the current flight speed?"

"The speed is about 100 kilometers per hour." Yi Zhengde blurted out: "The altitude should be around 200 meters."

"The speed is too slow and the fuselage is too small." Yi Zhizu said: "This kind of aircraft can also serve as a reconnaissance." After a pause, he continued: "Is the wind tunnel built? You can boldly try and improve it. For example, two layers of wings can be changed to one layer..."

After hearing this, the people behind him had already started to take out their laptops and start recording, "The entire aircraft must be larger, the fuselage must be widened and lengthened, so as to be able to carry heavier weights. We can't let the aircraft throw grenades from the air, right?

To drop bombs in the air, if they want to create huge lethality, bombs often have to be hundreds of kilograms, and it is impossible to carry only one bomb, right?

In addition, heavy machine guns have great lethality. You can consider equiping heavy machine guns or small cannons on the planes, which are the main weapon for aircraft to fight in the air. You should also be clear about how much the heavy machine gun consumes ammunition.

Therefore, the load capacity of an aircraft must be considered mainly. According to the different uses of the aircraft, it should be divided into reconnaissance aircraft, fighter aircraft, and bombers.

At present, the power is insufficient, so the main experience can be concentrated on smaller, mobile and flexible fighters, but even fighters need to carry at least three or five hundred kilograms of weapons and ammunition."

After a pause, he continued: "Fighters will be the main aircraft of the Air Force. I need to fix the machine gun at the nose position, and the pilot can directly shoot machine guns and drop bombs."

Yi Zhengde was stunned when he heard this, "When shooting from the nose, won't you hit the propeller?"

"How to not hit the propeller is the issue you should consider." Yi Zhizu said slowly: "There is insufficient power, especially for bombers, you can consider adding engines, twin engines, and four engines, and you can try it, although you don't need to consider the funds at all."

After a pause, he continued: "There is another thing that must be considered. Flight speed and altitude, speed is the biggest advantage of the aircraft. As for altitude, it is for safety reasons. You should know the range of rifles and machine guns. If the aircraft is shot down by rifles and machine guns, it will be a joke, so the altitude must be considered."

Yi Zhizu was watching the plane in the air while talking. Tang Chutian, who had rich flight experience, obviously showed off his intention and performed a series of performances around the airport, sometimes diving and sometimes pulling rapidly, sometimes turning left and sometimes turning right, turning reassuringly, light and flexible, like an eagle soaring in the air.

Looking back on the clumsy flight when I first watched the first plane show in Shanghai, I feel contented and satisfied. It seems that they have not been abandoned in the past few years. It is not easy to make such great progress in just a few years.

Thinking of this, he felt a little moved. Perhaps he should try to start the formation of an aviation brigade. The training of pilots must be ahead. After all, pilots cannot be trained in a short period of time.

As Tang Chutian's performance ended, a helicopter slowly flew over and waited to approach. Yi Zhizu couldn't help laughing. Although he had known that the fuselage of the helicopter was made of wood, he still felt like he wanted to laugh when he saw it with his own eyes.

The helicopter was designed completely according to the sketch he drew. The style was not bad, but it was very rough. Yi Zhengde explained embarrassingly: "The helicopter is still in the stage of exploring and trying..."

Yi Zhizu nodded. Helicopters are new things after all. Even if they successfully fly the helicopter, they are still not sure about the performance and structure of the helicopter, so they use wooden frames to facilitate improvement and adjustments anytime and anywhere.

When he approached the helicopter, he did not perform long performances, but just carried forward and circling left and right, and then slowly led the way down. Yi Zhizu said strangely: "Can't you hover?"

"Hoom?" Yi Zhengde was stunned and didn't understand what it meant.

Hovering means hanging in the air without moving. This is the biggest difference between a helicopter and an aircraft. Yi Zhizu didn't explain it, so he waved his hand. He was a person he had never seen before, but knew that the helicopter could hover. How could this be explained? Anyway, after a long time, they could figure it out by themselves.

After walking around the helicopter, he pulled open the cockpit and observed for a while without expressing any comments. He had seen the appearance of the helicopter, but never saw what was going on in the cockpit. After pondering for a moment, he said: "The helicopter should be equipped with two pilots."

Helicopters are different from fighters. Generally, fighters are one pilot, while helicopters are two pilots. He knows this common sense.

Yi Zhengde was very surprised and asked, "Why?"
Chapter completed!
