Chu Yun was at a secret factory outside the outskirts of the capital at this time. He seemed to have sensed it and looked to the west.

"Sir, is there something wrong with this newly developed aircraft?"

Feng Ru and his group originally brought Chu Yun to check their factory, but found that Chu Yun suddenly felt a little absent-minded, and thought that there was something wrong with the results of his group's research.

"No, it's just that I was distracted for a while." Chu Yun murmured in his heart, always feeling that something had happened.

"This is a new monoplane developed by our aircraft factory. It uses inspiration obtained from pigeons. Its aerodynamic shape is very similar to that of a bird. Its wooden frame is made of a layer of cloth on the outside. It uses steel pipes as a pillar and is pulled at the same time. The steel pipes are connected to the fuselage skeleton, which is very firm. Here, twisted wing tips are used instead of ailerons. The current standard is two seats, which can be used for two pilots to ride." Feng Ru introduced the huge "strange bird" in front of Chu Yun.

Chu Yun walked around the strange plane. What do you think of this plane... The length is about 10 meters, the wingspan is 14 meters, and it looks a bit weird, like a huge pigeon.

The pigeon-style aircraft is about 3 meters tall, much higher than Chu Yun. However, Chu Yun, who has seen the giant aircraft in later generations, does not think that the aircraft is too big. On the contrary, the aircraft with only two seats looks more like a big toy to Chu Yun.

This is too different from the real monoplane in Chu Yun's impression, just like a black technology aircraft that is still in the exploration stage, with unique shape but not perfect enough.

"Can it go to heaven smoothly?" Chu Yun couldn't help but ask.

"There is no problem at all. Its performance is far beyond our imagination. This guy weighs 650 kilograms in empty weight, and the weight of the two pilots and even explosives is less than 900 kilograms. Its wing area is 32 square meters and its ceiling can reach 2,000 meters." Feng Ru introduced.

"You mean 2,000 meters high? Just relying on this type of pigeon-like structure?" Chu Yun was incredible.

In his opinion, although the aircraft in front of him also has the unique structure of the aircraft such as propellers, engines, wings, tails, etc., the wings and tails imitated by the pigeon design also appear a bit primitive, and the skin is made of variegated linen, making it look thin.

"Don't you believe it? This is indeed very different from our previous biplane aircraft. When we were studying biplane, we were also studying monoplane aircraft. This monoplane performed well. We worked with the engine factory to study aviation engines, and produced an 86-horsepower 4-cylinder water-cooled piston engine, which provided enough power for it." Feng Ru and his group were very confident and proud of their design.

Seeing that Chu Yun was still a little unbelievable, Feng Ru and others exchanged their eyes and offered to perform a flight performance.

In order to verify that this pigeon-style aircraft really has practical effects, Chu Yun naturally agreed.

The aircraft factory was carried out in a vast place outside the capital. In order to ensure that the aircraft, a secret weapon that seriously transcends the era, was not exposed so quickly, almost all the villagers around the factory had been moved away, and soldiers were patrolling nearby to expel good people who wanted to get close to it.

A little further apart, villagers reported to the government that strange big birds were present in this place. However, when the government tracked down the location of the aircraft manufacturing factory, they would be notified that this was a research site of the military and strictly prohibited from entering the investigation. Over time, the government ignored this matter. Instead, the legend of "strange birds" was popular nearby.

As the consul of the empire, Chu Yun certainly would not take the risk of flying the plane himself. In this era, the crash rate of planes was too high and the cost was very high. He and several senior officials in charge of this project came to inspect the project. Ella from the Intelligence Department also followed Chu Yun. She had heard Chu Yun privately describe many future scenes and was full of expectations for humans to conquer the sky. At this time, she seemed a little excited to see Feng Ru and others about to start flying performances.

"Feng Ru, do you want to fly the plane yourself?" A designer at the aircraft manufacturer asked when he saw that Feng Ru was going to operate the pigeon-style plane himself.

"If you are not satisfied with the plane you participated in the design, why would you harm other pilots?" Feng Ru and another pilot climbed onto the two-seat pigeon-style plane.

The experimental pigeon-style aircraft has only two seats and is basically without weapons. One pilot is mainly responsible for manipulating the lifting and lowering of the aircraft, and the other pilot is responsible for observing and firing with muskets or even igniting the fuse of the explosive pack, and then throwing the explosive pack below.

Although it is just such a simple attack method, the fear that ruled the sky brought to the civilian soldiers of this era is like a miracle.

When Chu Yun first came to this era, he had the idea of ​​developing an aircraft, but until now, Chu Yun has been constantly opening up various technologies to lay the foundation for aircraft technology, especially engine technology and petroleum technology, the aircraft finally became quite good - although the primitive pigeon-style aircraft in front of him is still far from the aircraft in Chu Yun's impression.

"Sir, can they really fly into the sky of 2,000 meters? That's 2,000 meters, higher than ordinary hills. Crossing mountains and ridges is not a problem at all." Ella stood beside Chu Yun, her eyes full of expectations.

Even when she came from the early 19th century, steam engines began to become popular, who could have thought that one day human beings could conquer the sky that they looked up to every day?

"There is definitely no problem with a height of several hundred meters, and 2,000 meters should be the limit." Chu Yun saw Feng Ru and others swear that pigeon-type aircraft can fly to an altitude of 2,000 meters, and they must have conducted many experiments and tests to draw such a conclusion. Industrial products like this that are realistic cannot be lying.

Feng Ru and another pilot put on simple windscreen glasses, extended their thumbs to Chu Yun and others, and prepared to take off.

In this era, there are no command towers, no cement runways, no complex communication systems, no ejection chairs and parachutes, and even the weight of the aircraft plus the weight of the two pilots is less than a ton. They can only conquer the sky step by step with their own operating experience and courage.

Chu Yun used to think that the scene of the propeller plane, the pilot who took off with a windshield, was a bit handsome, but he didn't expect to see it here.
