Zeppelin is a general term for a type or series of rigid airships, which was further developed by the famous German spaceship designer Ferdinand von Zeppelin in the early twentieth century based on the airship designed by David Schwartz. Due to the maturity of rigid airship technology, large-scale is possible. Because of its superior ability compared to contemporaneous aircraft, it can carry large cargo, which is a brilliant achievement in the early days of the aviation industry. "Led Zeppelin" is synonymous with the use of hard-style airships.

On July 2, 1900, an airship designed and built by Count Ferdinand von Zeppelin of Germany made its first flight near today's Friedleport. The airship was built in 1 hangar floating on Lake Constance with an aluminum shell wrapped in wire and wrapped in cotton cloth with 16 hydrogen capsules. Two 16-horsepower engines allowed the airship to reach speeds of up to 14 miles per hour, and the Zeppelin served as an important commercial flight on both sides of the Atlantic. During the American Civil War, von Zeppelin first took to the air in a balloon while serving in the Union Army, and he has been developing airships since 1891.

At that time, the main uses of giant airships covered both civilian and military fields. On the civilian side, Deutsche Airship Transport can be regarded as the founder of modern commercial aviation, having been very active before the outbreak of the First World War. After the outbreak of the Great War, military generals of various countries noticed the usefulness of the flying boat, so they put it on the battlefield instead, serving as aerial bombardment or reconnaissance scouts.

Germany's defeat in World War I brought the operation of Zeppelin to a quagmire, but Hugo Ecner followed up on the legacy of the late Count Zeppelin and revived Zeppelin in the 1920s, reaching its peak in the 1930s. At that time, several popular giant spacecraft, including the LZ127 "Count Zeppelin" and the LZ129 "Hindenburg", were rich in profits on the transatlantic routes between Europe and the United States. However, in 1937, the Hindenburg caught fire and crashed in New Jersey, USA, which is also known as the "Hindenburg Air Disaster".

Ouyang Yu's super magic modified Zeppelin airship is from the hand of Isara, this girl is a natural alchemist, a genius in ten thousand, after following her brother Virugin to the Duchy of Lucerne, she joined the national alchemy laboratory established by Ouyang Yu to study the combination of earth weapons and otherworldly alchemy.

Although the natural science of the earth and the alchemy technology of another world are very different, they are both applications of natural forces, and there are many similarities and similarities, and the purpose of Ouyang Yu's establishment of the National Alchemy Laboratory is to learn from each other's strengths and make his weapons more deadly.

The Super Magic modified Led Zeppelin is presided over by Isara, and is the first improved and successful weapon of the National Alchemy Laboratory, using an inert gas unique to another world to replace the originally dangerous and flammable hydrogen, flying at a higher altitude with the same volume, and the load capacity is also several times that of ordinary Zeppelin.

The shell of the airship is strengthened with alchemy runes, which is light and strong, and can withstand the fire of rifle bullets, and if it is thickened, the defense can be further enhanced, even if it is a 12.7mm armor-piercing bullet, but the weight of the airship will increase by three times, so the magic modified version of the airship is only in the engine, fuel tank, The crew cabin and other key parts are thickened armor, there are 32 airbags in the airship, and there is a certain amount of armor protection between the airbags and the airbags, which can ensure that the entire airbag will not leak due to the shell being penetrated, and the survivability is still very high.

The power uses four 160 horsepower engines, and two otherworldly jet engines are also installed experimentally, with a maximum speed of 120 kilometers per hour, an economic speed of 70 kilometers per hour, and a full fuel can fly 6,000 kilometers at a time, and the time in the air is almost unlimited.

The structure of the jet engine of the Otherworldly Alchemy version is very simple, because it is only in the initial stage of reliability and efficiency, the engine is cylindrical, similar to the jet engine on the earth, one intake and one jet, but the air intake is not by the fan blades but by the magic array, the engine is engraved with dense magic array, the wind magic array sucks the air from one end into the combustion chamber, the fire magic array in the combustion chamber heats the air instantly, and then spews out through the wind magic array at the tail, the whole process is similar to the ramjet engine on the earth, but because of the active and rapid inhalation of the alchemy magic array, even when prohibited or at low speeds, ramjet engines on Earth can only be used in environments above Mach 3.

The jet engine installed on the airship for experimentation, the current power is 880 horsepower, and it needs to be overhauled after 30 hours of work, mainly because it has not yet developed qualified high-temperature resistant materials, once the research of materials has made a breakthrough, then the reliability of this engine has been guaranteed.

There are three types of Zeppelin airships, reconnaissance type, armed type and bombing \\ transport type, the airship has the characteristics of long stay in the air and stable flight, it is best for reconnaissance and ground support, reconnaissance and bombing, transport type only basic self-defense weapons, installed with six twin 12.7mm machine guns, bombing, transport airship can be loaded with five tons of various types of bombs, or a company of soldiers and equal weight materials.

In addition to the basic self-defense weapons, the armed airship is equipped with four 40-mm guns, two on each side of the fully enclosed boat-type gondola, and a 76-mm howitzer, the ground support airship's pod is specially reinforced, otherwise it cannot withstand the recoil of the howitzer, and the howitzer is installed at the bottom of the pod and can rotate down 360 degrees.

The idea of an armed airship naturally came from the AC-130 of the US military, and Ouyang Yu couldn't play the tall AC-130, so he used the Zeppelin airship to modify a copycat version of it, and the test results were not bad, which made her more satisfied.

A total of 36 airships appeared in the sky over the valley of the rebels, 24 of which were armed airships, and the large and small shells fired by these 24 armed airships quickly cleaned up the living dead on the ground, and the "invulnerable" living dead could not stop the shooting of the shells at all, and all of them were blown into fragments and completely turned into immovable dead objects.

The twelve bombing and transport airships slowly lowered their altitude under the cover of the armed airships, and only stopped when they descended to only a dozen meters, and then each airship lowered six ropes, which one soldier used to slide down the airship.

"Put down your weapons and crouch down with your head in your hands!"

A battalion of Ouyang Yu soldiers came down from the airship, some of them were on guard outside, and some of them surrounded the surviving rebel fighters and shouted orders for them to surrender.

With the muzzle threat of the armed airship in the sky, the more than 100 surviving rebel soldiers dropped their weapons without much thought, and obediently squatted down with their heads in their hands, but one person did not do this, he was Lancelot, Lancelot after carefully looking at the uniforms of the soldiers of Ouyang Yu's army, not only did he not have a frightened expression but showed a happy smile, because of the style of the military uniforms on the soldiers of Ouyang Yu's army, he had heard it more than once, it was rumored that this army had defeated the imperial army several times, and the invincible imperial army did not dare to invade their territory, and this time the name of the army was the Duchy of Lucerne army。

"May I ask if you are the Principality of Lucerne Army of His Excellency Count Ouyang?!"

Lancelot excitedly ran to the front of an officer of Ouyang Yujun and shouted, his shouting startled the officer, and the officer pointed a gun at him and warned: "Hold your head and squat!"

But Lancelot, who was already in excitement, turned a deaf ear to the officer's warning, and shouted loudly again: "Are you the army of the Duchy of Lucerne of His Excellency Count Ouyang?!"

The officer found that Lancelot was not hostile and put down his gun, but he still did not let his guard down, but he still answered his question, "Yes, we are the army of His Excellency Earl Ouyang, who are you?"

"Is it really His Excellency Earl Ouyang's army? Great!" Lancelot pointed to himself and said, "I am the leader of this rebel army, is His Excellency Earl Ouyang also here? I wonder if I can introduce me?" I have a lot to say to His Excellency the Earl. ”

"Shut up!" the officer shouted impatiently, "I can pass on your request to you, but Comrade Leader can't see you, then ......" The officer said suddenly stopped, and showed a listening expression, as if someone was talking to him, and after a while he said to Lancelot: "Come with me, Comrade Leader wants to see you." ”

"Your Excellency the Earl knows me, and you want to see me...... This...... I'm so honored. ”

Excited, Lancelot followed the officer towards the cave, and when he was about to reach the cave, he saw Ouyang Yu, who had changed into a Soviet military uniform, and the German soldiers guarding her.

The officer walked up to Ouyang Yu and slammed his heels together and saluted, and said loudly: "Dear comrade leader, the commander of the first battalion of the airborne regiment reports to you, please instruct!"

Lancelot was dumbfounded for a moment, he didn't react for a while, and pointed at Ouyang Yu by the sleeve of the commander of the first battalion of the airborne regiment and shouted: "She is the princess of the Phoenix Empire, an enemy, how can you salute her?"

"Presumptuous!"

The battalion commander angrily kicked Lancelot's knee, knocking him to his knees in front of Ouyang Yu.

After coming to his senses, Lancelot realized what he had done, and raised his head incredibly to look at Ouyang Yu, Ouyang Yu also looked at him condescendingly and said: "Introduce yourself, the first-class earl of the Duchy of Lusen, Yu Ouyang is below, not the princess of the Phoenix Empire, I hope you don't make a mistake next time." ”

After Ouyang Yu finished speaking, he raised his right hand and slapped it heavily on the face of Lancelot, who was already stupid.
