The time crept into the middle of May. The Xianyang Air Defense Flight Unit began to change its equipment. They no longer use the royal coat of arms. Instead, an eagle is used to hold an iron anchor. This indicates that they are naval aviation. Iron anchors mean that they are subordinate to the navy. and not separately or subordinate to the Army.

The insignia of the Celestial Army is an eagle with wings spread. The Army, on the other hand, holds the badge with a cross pattern of muskets and artillery. Special forces have special patterns. For example, each bombing squadron has a different pattern. The one placed on the front line of Qi uses a black bomb pattern. And this is a fierce hammer that belongs to the Western Regions.

The specialization of the badge meant that the competition within the Qin state was fierce. This fierceness exacerbates the sense of unity and honor within the team, which is very useful for taking advantage of the increase in the combat effectiveness of the army.

The improvement of combat effectiveness also requires technical equipment. In the Western Regions, the Qin State urgently ordered the withdrawal of most of the airships. Only some combat aircraft were left as air support.

The subsequent order was even more surprising. King Qin ordered the cancellation of all airship flight missions. This is a direct no-fly order. And not only airship troops. There are also civil airships.

The specific reason is that the latest model of airship produced by the Qin State uses a lot of metal. The drilled steel plate serves as the main skeleton. The use of steel plates replaces the original wood. In order to reduce weight even further. A new type of metal is applied. Aluminum began to become the bracket and skin for rigid airships.

The interior began to be filled with airbags. The use of plastic strengthens the seal. But the gas hasn't changed. Dangerous hydrogen is still used. And in the laboratory has been intensively studied the study of helium. The main result is the shielding gas for arc welding. The industrial method of extraction is from natural gas. The main thing is that there is natural gas in the coal mines of the Qin State. This gas poses a huge threat to coal mine production. An unexpected discovery during spectral irradiation.

But compared. Helium gas due to is just appearing. Cost price. In particular, the cost of research cannot be reduced. So the price is higher than hydrogen. In cost considerations. Hydrogen is still the main filling gas for all airships.

But the accident caused the King of Qin to issue such an order as a no-fly order. The accident was treated by a series of air accidents that occurred together into one major event.

During the war against the Western Regions, there was an incident where the airship spontaneously combusted and crashed. The reason for the investigation is unknown. However, at that time, the structure of the airship was covered with a mixture of metal and textiles. Shangwen believes that it is caused by static electricity. This is the biggest killer of airships. Fly in the air. Especially after the speed is raised. The friction with the air increases. There is a high probability that static electricity will occur.

But the incident has not received enough attention. A serious air crash also occurred during the transportation of the private airship. At that time, the airship was transporting about thirty Zhao infantry units who were preparing to participate in the battle in the Western Regions. Some of the supplies were also delivered. But I don't know why. The airship suddenly burst into flames in the air. The driver had not yet had time to make a forced landing. The airship exploded in the air. At that time, the altitude of the flight was at an altitude of three hundred paces. No one survived the scene. This incident first banned all airship flight plans in the Western Regions.

But what happened next led to the airship being grounded outright. On the front line of the Qi State. A reconnaissance airship also caught fire in the air for unknown reasons. Fortunately, the captain urgently ordered a parachute jump.

But the airship had already penetrated within 150 miles of the Qi country. All members of the airship were captured. Although Shang Wen instructed the Celestial Army to allow capture in case of emergency. It is even possible to say some partial military secrets for the safety of life. For example, the number, the commander of the unit or something. However, the king of Qin did not allow the Qin state to have captives. The King of Qin would rather see the cold corpse than see the Qin fighters captured. He believes that soldiers should maintain integrity. I'd rather commit suicide than be a prisoner. Especially the initiative to surrender as a prisoner. If you have the chance, you should draw a gun and kill yourself.

In short, this incident led to the eventual grounding of the airship. In particular, the King of Qin did not want to see the fact that the airship caused the Qin fighters to be captured.

All airships are in the process of finding out the cause. and before the issue is resolved. Airships are not served as the main transport-combat platform. The issuance of a no-fly order. All of a sudden, there was a large vacuum in the air power of the Qin State.

The emergence of this space is a development opportunity for aircraft building. Only combat aircraft exist on the front line. The demand in the air is particularly great. Especially the Qi front. Because of the no-fly order. In the air, the established fact that Qi has taken air supremacy over some areas has temporarily appeared.

Especially after the airship was banned. On the front line of the Qin State. The Qin State Airship Bombing Brigade transformed an aerial machine-gun airship on its own. The airship is extremely lethal against the country's hot air balloons.

This airship was armed with four large-caliber Point 60 machine guns. This machine gun bullet can easily tear through the balloon's airbag and shoot it down. Most importantly. He spent a lot of time in the air. Turn off the engine. Or keep it at a low and constant speed and stay in the air for a longer time. This will allow for effective control of air supremacy in the region. Sometimes. The airship will also lower its altitude and fire directly at the ground with a machine gun. caused a lot of damage to the Qi country. Transport vehicles were also effectively blocked. Especially the ox carts that carried the grain. Machine guns can kill the entire convoy of cattle. This is a great loss for Qi State.

But after the airship was banned. Only fighters of both sides remained in the air for three hours. This gave the other party a chance to break through the air blockade of the Qin State.

In fact, the actual use of airships is far greater than that of airplanes. Airship in terms of laying cables. There is a big advantage. In particular, his carrying capacity. It took a while for the aircraft industry in the Qin State to create transport aircraft with a certain transport capacity. But the carrying capacity of the airship is already comparable to that of the Hercules transport aircraft.

But airships intensified with the use of new materials. led to a series of Shangwen air tragedies. Make airship transport a usable but not usable point. Shangwen recommends using helium, which has excellent stability. And not hydrogen. Because. The Ministry of Transport reported. If air transport cannot be resumed as soon as possible. Then some special transport cases cannot be resumed.

In order to lift the no-fly order as soon as possible. Shang Wen directly ordered the regulations to be transported by airship. In the future, the airships produced by the Qin State uniformly used helium airships. Hydrogen airships are no longer used. Flight can be resumed after helium is reused.

Thereupon. A large number of airships began to be returned to the factory to replace the fill gas. For a while, the power of the Qin State airship disappeared. Aircraft temporarily became the protagonist of the air. The aircraft power was partially adjusted.
