The weapon tycoon who traveled to Daqin

Only he himself can understand what King Yan was thinking, but to the State of Qin, these are all so-called because King Yan paid a huge expenditure of up to 500,000 gold for this. In addition to the gold payment, most of the rest relied on raw materials. He exported to Qin in exchange for more than just this. He also misappropriated part of the military expenses. His army was in arrears with military pay. This is not a good sign.

In contrast to the King of Yan, the King of Qin expressed a strong interest in aviation. Especially when the Air Force established the club, the King of Qin gave great support. Qin's aviation industry also started with the production of hot-air airships. The King of Qin did not specifically issue releases to the aviation industry.

Qin's aviation industry has developed rapidly due to the special treatment given by the King of Qin. Qin's airships are no longer the hot-air airships of the past. Although hot-air airships are simple to operate, they cannot carry out long-distance voyages.

Hydrogen airships using hydrogen as the filling gas began to appear on the stage. At first, the pilots and flight engineers of Qin could not solve a problem. When the airbag was filled with hydrogen, the airship gradually rose. As the altitude increased, the atmospheric pressure gradually decreased and the hydrogen in the bag expanded. The airbag expanded larger and larger. Later, a pilot desperately wanted to survive and poked a small hole in the hydrogen. This move added a deflation valve to the airship so that the airship could fly safely.

If this move was made earlier, it would definitely be a waste because it was not easy to obtain hydrogen at first. But with the emergence of power plants, Qin State began to use the method of electrolyzing water to obtain it. This method consumes a lot of energy, but it is easier than using chemical reactions to produce hydrogen. Much [

However, accidents have also occurred with hydrogen airships. The airship was equipped with a heavy steam engine. The line of fire from the steam engine collided with the released hydrogen. As a result, the hydrogen airship burned in the air. However, the pilot successfully parachuted and his arm was severely burned and he was unable to fly.

With the occurrence of the accident, the hydrogen airship was improved again. A man named Li Kong invented the air room. This distant relative of Li Xin was very capable of flight transformation.

He made a balloon equipped with an air chamber. Its shape is like a spindle, which is very similar to a modern airship. The balloon has a large silk capsule on the outside and a small air bag inside. There is a gas valve on the small air bag. The outer bag is filled with hydrogen. The balloon generates buoyancy and rises into the air. The inner bag is used to inflate the air. This small air bag is called an "air room".

Before the balloon lifts off, the "air room" is filled with air. When the balloon rises to a certain height, the "air room" is opened to release a part of the air. After the outer bag is inflated, the "air room" shrinks due to compression, causing the outer bag to shrink. The inflation pressure was reduced to ensure that the air bag would not burst. This invention solved a major problem in balloon lift-off and was another major breakthrough in the history of airship development. After that, the "air room" was quickly used on all airships and has been used ever since. Used so far

However, the pace of flight improvement has not stopped yet. The establishment of the Heavenly Army here relies on huge technical support. The attention of the King of Qin allowed these proud men to work harder. They were the first to use internal combustion engines on airships. The modification strengthened the sealing effect and added a water tank to cool the cylinder. Moreover, the Space Army had a lot of diesel, which allowed them to be more free to fight. For this reason, the airship initially carried out a long-distance flight without any landing midway. He actually flew more than a hundred miles. When King Qin heard the news, he was extremely happy.

In addition to the airship, another absolutely exciting flight made King Qin a little obsessed. Not only King Qin, but also Ying Yu wanted to try the glider as another way of flying. Although the flight conditions and flight range are really unsatisfactory, it has one thing better than the airship. The absolute advantage is speed

King Qin and Ying Yu are both naturally interested in things with speed. The speed of a glider exceeds that of an airship. Especially when the wind is suitable, the glider can fly freely. This new way of flying makes King Qin and Ying Yu eager to try it. However, the Heavenly Army Officers tried to dissuade them, saying it was too dangerous.

Under the dissuasion of some military officers, King Qin stopped his adventurous actions. However, King Qin did not give up this attempt. Ying Yu also had her mind started to build the idea of ​​​​an airline.

The flight competition has begun. The competition seems a bit interesting, mainly with various airships participating in the competition. There are more than 20 airships of various sizes floating in the sky. They are like well-fed sheep in the sky, and they are very leisurely.

But there is a strange thing lying on the ground, a new type of aircraft.

Wang Dao is a poor boy from Taiyuan. He worked in a bicycle factory and is very familiar with various mechanical principles. He has been interested in flying since he was a child. He dreams of flying like a bird one day, so he came to Xianyang to see the world. At the bicycle factory, he He found a job where he learned to read and read newspapers. From the newspapers, he learned that the Qin State had established the Heavenly Army and later established an aviation club. He then paid an expensive fee to join the aviation club and became a pilot.

You must know that flying is a game for the brave, and an airship is expensive to build, which makes flying an entertainment project for upper-class children. They have monopolized all flying projects and it is difficult for ordinary people to enter because the cost is really expensive. The cost exceeded the twenty-year savings of five middle-class families.

But Wang Dao doesn't care about this. What he cares about is flying. He is the best pilot with a high level. Many people are willing to fly with a pilot like him. He can solve various problems and he enjoys this kind of treatment very much.

Flying is very beautiful, the feeling of freedom is like that of a bird. He always thought so, but the airship is too slow and bulky, and does not have the lightness of a bird.

At this time, the emergence of gliders allowed him to see the opportunity to fly like a bird. Internal combustion engines are mainly diesel engines. Although they are a bit bulky, they are much lighter than steam engines. What would happen if a diesel engine was installed on a glider? This idea prompted him to develop the Qin Guo It is also the first aircraft in all Chinese history. His aircraft will usher in a new era in the history of aviation. The era of aircraft will replace the dominance of airships. But now he needs to shake the handle desperately to start the diesel engine.
