"Is this the biplane you have developed?"

Chu Yun surrounded an airplane parked on the lawn, which finally looked very similar to what he remembered. On the plane, he also painted a dragon totem with red paint.

Previously, Feng Ru and his team took out a single-wing pigeon-type aircraft. Although they could soar in the air, they were still very different from what Chu Yun believed to be a practical propeller aircraft. Pigeon-type aircraft was just a bionic attempt in the early stages of aircraft development.

The aircraft factory has developed a practical new aircraft.

A biplane less than 6 meters long parked on the lawn, with an altitude of no more than one floor.

What is the concept? It is about the same size as a light truck.

The early biplane was like an enlarged toy, and Chu Yun could easily climb onto the plane without any tools.

In any case, this biplane propeller aircraft is very similar to the early propeller aircraft that Chu Yun remembers.

"The pilot is 5.7 meters long, 2.6 meters high, 8.5 meters wingspan, 21.4 square meters wing area, 420 kilograms of air-cooled star engine, and 110 horsepower air-cooled star engine is used. It is a reciprocating internal combustion engine with cylinders arranged around the crankshaft. The piston is connected to the crankshaft through a main connecting rod..." Feng Ru introduced the basic parameters of the aircraft to Chu Yun, focusing on emphasizing the heart of the aircraft engine, that is, the aircraft engine.

Chu Yun only knew that the aero engine had made greater progress, and the shape of the biplane was closer to his ideas. As for the working principle of the star engine used, Chu Yun was very difficult to understand.

But there is no problem with this. Professional machines can be solved by professional talents. They only need to care about the performance of the aircraft.

"What is the flight speed, altitude and battery life of this thing?" Chu Yun asked.

"The maximum flight speed may reach 185 kilometers per hour, the altitude can reach 5,000 meters, and the battery life is 2.5 hours." Feng Ru introduced the practical performance of the new aircraft to Chu Yun one by one.

Chu Yun's eyes lit up, as if the biplane could be put into use.

"Can you load explosives?" Chu Yun asked.

"It can load up to 45 kilograms of explosives."

"This is already very exaggerated..."

Chu Yun thought about it and it seemed that the local area did not need a biplane much.

Overseas wars may or may not be needed, because today's infantry and artillery can push continental areas by using traditional battle tactics.

It’s better to use airplanes to sprinkle pesticides and other people’s livelihood purposes...

Before the emergence of transport aircraft, there was no military need, so the purpose of the aircraft was not very big, and both passenger and freight capacity were urgent.

If used in military terms, it can be used to detect and drop bombs.

What is more convenient is that the biplane has good low-speed flight performance, simple instrumentation equipment, can take off at a simple airport, and is also convenient for maintenance.

Next, Feng Ru flew a new biplane to perform a flight for Chu Yun.

In Chu Yun, who has seen large passenger aircraft from later generations, it is a very magical thing that this big toy-like biplane propeller can fly smoothly.

The engine drove the propeller to rotate rapidly, and the biplane gambled on the runway for a short distance before flying into the air against the wind!

A group of officials who arrived with Chu Yun had already seen the flying performance of the pigeon-style plane last time. They were not particularly shocked that the biplane propeller plane could fly into the sky. They roughly understood the principle.

"If we could use this new weapon called an aircraft when we were fighting in the past, we could throw gunpowder on the enemy's heads and easily destroy the enemy's formation and morale, as if there was help from God." An official said.

The plane appeared too late.

In the past, when fighting in the local area, there were two-wing propeller planes that were about to scare the enemy to death.

Unless you see the biplane propeller planes close by, who would have thought that people could fly into the sky and bring explosives?

"We have several strongholds in the West, and we can transport several planes to the West through steamboats or sailboats to shock them." Chu Yun thought about it carefully.

The local government has limited functions for both military and civilian purposes, so it is okay to scare people if you pull them out.

Feng Ru flew a biplane and performed for half an hour. The flight was very smooth, and the performance of the aircraft was better and safer than other models before.

"Please name this kind of aircraft." Feng Ru returned to the ground, turned off the engine, and asked Chu Yun to name the first practical biplane propeller aircraft.

"It's better to call it the Dragon Propeller Aircraft, and then develop the second and third generations later."

Chu Yun gave the world's first practical biplane propeller aircraft a name.

Because there is no need for war, the Dragon aircraft does not have a machine gun loading, nor does it have a special system for loading machine guns, but only improves the structural design of aircraft engines and aircraft.

"I think there are two development directions next. One is to load 1 to 2 machine guns and external explosives on the dragon aircraft, which will become fighter jets and bombers. The other is passenger aircraft and transport aircraft, used for passenger transport and freight transport. For passenger transport, first consider how many passengers can be transported, and freight transport can be used to transport mail first."

Chu Yun mentioned two main uses. The two research directions have great commonalities. Many technologies can be used for military and civil use at the same time. Of course, there are some differences.

"We will be committed to the research of monoplanes and all-metal aircraft, and plan to produce a passenger aircraft that can reproduce four people." Feng Ru said.

"Where is a parachute? Is there a parachute protecting the pilot's safety?" Chu Yun asked.

"We already have parachutes that can fold and pack the parachutes, parachute ropes, etc. and place them in the cabin, suitable for flight personnel to use. However, there are still certain dangers and cannot be used easily." Feng Ru replied.

“It’s safer to have a parachute than not.”

Chu Yun encouraged the large-scale use of parachutes. Pilots and aircraft researchers are important reserves. If something happens to the plane, the parachute may be able to save your life.

"You can produce five dragon-type aircraft, perform flights at the International Nations Expo later, or even throw explosives, which scares the princes, nobles and ambassadors of all countries."

Chu Yun had a bold idea to use a biplane to deter the personnel coming to participate in the World Expo by force. After the World Expo, an aviation team could be set up to fight in Europe.

"Sir, I want to learn to fly a plane." Ella said to Chu Yun on the way back. She was staring at her eyes just now when she was watching the flight performance.

"...Are you sure?" Chu Yun was quite surprised.
