The propeller of the pigeon-type plane began to rotate, making a buzzing sound, stirring up the surrounding airflow, causing Chu Yun's clothes to slightly illuminate.

The pigeon-type plane, which was less than 800 kilograms, began to glide on the gentle dirt road, and soon it quickly rose against the wind and soared in the air!

As a pilot, Feng Ru could see Chu Yun and his group of people and buildings on the ground getting smaller and smaller. The storm in the air made his face deformed. Fortunately, he had a windscreen, which allowed him to observe the ground scenery that began to become small without any obstacles.

Chu Yun also saw the 10-meter-long plane on the ground becoming like a big bird, and a feeling of familiarity surged into his heart.

Finally, in this era, I saw a decent propeller plane.

Although it is still in the exploration stage and looks a bit strange, if it continues to develop with this momentum, it may be possible to see jets in your lifetime.

"It's really possible to fly into the sky and not fall yet! How did this be done!"

The officials following were stunned, and Ella even pulled Chu Yun's clothes and looked at the pigeon-style plane hovering in the air.

Chu Yun specially picked a clear and cloudless weather to inspect the results, so they could easily see the pigeon-type aircraft in the air, scaled according to the reference objects in proportion, and the pigeon-type aircraft driven by Feng Ru took off at least 1,000 meters.

This is a very impressive progress. The aircraft is not a glider, but an aircraft that can freely manipulate the direction - there are still many shortcomings, but it is enough to cause a sensation in the whole world at this time!

"If you use this object to conduct reconnaissance during combat or throw explosives down, you can easily defeat the enemy." Ella was a naval officer. There was no concept of air force in her time. She always praised the navy more than the army.

However, the appearance of the plane in front of her seemed to give birth to a new army, which made her keenly realize its tactical value.

"The current aircraft are not good yet. They actually dare not get too close to the ground. It is basically difficult to hit the target with explosives thrown by high-speed movement. It is possible to detect and deter the enemy..." Chu Yun also knows the tactical value of the aircraft.

It’s a pity... For his army, it doesn’t matter whether there are planes now. Just queuing up and shooting can sweep across Europe.

Chu Yun currently values ​​its transportation value more, especially establishing airports and oil depots between various overseas strongholds, which can patrol all over the world, just like a navy, while controlling the sea and the sky.

Chu Yun thought about whether he could create a turbojet aircraft in the future, which could shorten the distance between the East and the West. Otherwise, he would have to hit a disobedient kingdom, and sending troops from the local area on a boat would be too far away.

While he was thinking about it, Feng Ru and his two flew in the air for half an hour before they started landing. The pneumatic tire made of rubber material landed first. Due to the violent friction with the ground, a large amount of heat was generated. The entire pigeon plane also shook, which made everyone inspecting the ground sweat for the pilot.

"In fact, it can fly longer and the range can reach more than 120 kilometers. But I'm afraid that adults will get tired of it, so I landed in advance." Feng Ru and another pilot jumped off the pigeon-style plane and took off their windbreak eyepieces.

"I can't get tired of seeing it all. The sea and the sky are areas we have not conquered, and this is our tool to conquer the sky." Chu Yun praised their achievements very much.

"Our aircraft manufacturer has carefully studied the solutions proposed by adults. Adults have a special liking for monoplane aircraft, so we are unique in designing pigeon-type aircraft using the principles of bionics as an exploration of monoplane aircraft. However, at present, biplane operation is stable, reliable in structure, flexible in maneuver, and should be more suitable for the current situation." After Feng Ru and other aircraft factories developed a practical monoplane, they seemed not very satisfied with this monoplane aircraft, and believed that biplane aircraft was better than monoplane.

"You can decide your own research direction based on your experience. I just remind monoplane to be a good development direction. In particular, it is necessary to increase research on aero engines and aviation materials, which is the foundation of the foundation." Chu Yun said.

He overestimated his current technical level. Technical conditions limited the development of monoplane aircraft. At this time, the power brought by the aircraft engine was not large enough. Various metal materials and corresponding processing techniques did not come up, and physicists' research results in the field of aerodynamics were still ignoring the glory. All these limitations made the streamlined monoplane unable to come out for a long time.

"We will try to develop higher-performance aero engines and better aviation materials." The era in which Feng Ru and his group lived was just an era of infancy in aircraft. Many experiences have to be explored by themselves, and they can only constantly encounter problems and solve problems to continuously improve their own technology.

After Chu Yun learned about the progress of the aircraft manufacturer, he brought people to the factory to visit. There were more than a dozen aircraft engines of all sizes. Obviously, these people were also exploring how to produce their own engines and at the same time improving the performance of the engine.

There is also a biplane that has not yet been formed in the factory. The engineers inside said that it is still a semi-finished product and will undergo tests after completion.

After visiting, Chu Yun was quite satisfied with the progress of the aircraft factory. The main reason was that the knowledge of later generations made Chu Yun's taste tricky. Without military purposes, the development and use of the aircraft in the early stage was really worrying. If it weren't for the two world wars, it would be hard to say whether the aircraft could develop rapidly.

There were several four-seat cars waiting for Chu Yun and the others outside the factory.

Since Sofia took the initiative to ask for a car, Chu Yun also went to the engine factory to ask for several four-seat cars. Compared with Princess Sofia's more crowded two-seat cars, these cars are convertible cars with front and rear rows, of course, the cars were still very simple at this time.

"One day I also want to learn how to fly a plane and go to the air to take a look." Ella sat next to Chu Yun and pointed to the pigeon-style plane parked in the open space.

"It's better to wait until the aircraft's technology is more mature. Since its establishment, several pilots have died due to the experiment..." Chu Yun said the unknown secret.

As a pioneer of a technology, the situation is often very dangerous, especially when flying manufactured aircraft at high altitudes.
