For the Spring Festival, Li Jingmai invited three Hui troupes to set up a stage to sing big operas in Anqingsu County and Lieshan Town. Therefore, the Spring Festival celebration was very successful, and both the family and all parts of Anhui were very satisfied with Hu Xiaoyan's arrangement. If the data is shown, then it must be the effect of the people's will plus fifty.

It doesn't matter what the people are outside, because that's inevitable. What satisfies Hu Xiaoyan the most is that Angel finally got rid of the gloom she had when she first arrived. After the Spring Festival, she went to the middle school hall of her third brother Hu Pinsan to become a teacher. It is very interesting to be busy every day, and Hu Xiaoyan thinks that Angel is happy to get rid of the strange eyes of Li Jingmai and others.

After the Spring Festival, Hu Xiaoyan almost moved to his aircraft base. There are not only Lawrence's intelligence training base, Wang Wenyuan's aircraft research and development base, but also the airship research base from Germany.

Wang Wenyuan's research and development on the airplane has always been unable to stay in the air for a long time due to the weight of the aircraft, which has led to the stagnation of research, and Hu Xiaoyan had no choice but to let Wang Wenyuan join the research of the airship. The Zeppelin manufacturing company sent ten professional technicians, including Ludwig, Ludwig, Zeppelin's deputy. As for Zeppelin, Germany will not let go. The five large airships in the order were produced in Germany and then shipped to Lieshan for assembly. It was assembled before the Spring Festival, and this time I came to participate in the first flight at the invitation of Ludwig and Wang Wenyuan.

However, because Hu Xiaoyan has not planned to make this new weapon appear now, the test flight is scheduled for the evening. Although the Japanese spies were caught by Lawrence, the Japanese were simply one after the other, not afraid of life and death. If you can keep it secret, keep it a secret.

At eight o'clock in the evening, it was already dark outside, but the base was brightly lit. Due to Hu Xiaoyan's request, neither Ludwig nor Wang Wenyuan boarded the airship. Safety is still very important, these two people are the most powerful flying experts under Hu Xiaoyan at present. Ordinary soldiers would not blink an eye when they killed a single Hu Xiaoyan, but these two people were injured a little, and Hu Xiaoyan had to worry for a long time. Because they're all "hens" that lay golden eggs! Of course, the airship is not the 70-meter-long model that Hu Xiaoyan ordered. Rather, it is a large 120-meter-long airship. Small airships are cheap and easy to experiment. But his attack power was too weak, and the number of loaded shells was too small.

There were five people on the airship, one of whom was a diesel engine technician, a hydrogen airbag technician, and a student of an airship expert, all three of whom were Germans. The other two are both Chinese. A temporary driver, a guard in response to emergencies. The five of them all had parachutes made by Hu Xiaoyan improvised on them. Once an accident occurs on the airship, the guards will open the door of the airship as soon as possible and organize the other four people to parachute. There are also twenty observers in various other parts of the airship, who will record the conditions of the airship before and after liftoff, and provide the necessary experience support for the next lift-off of the airship. They are very pitiful that they don't have any parachutes, it's not that Hu Xiaoyan doesn't give them, but the parachutes are currently very technical, and it is difficult to produce them in large quantities. For this test flight, Hu Xiaoyan tried his best to write down all the safety details that he could think of, so that the technicians could do a good rehearsal.

They were all standing on the outer platform of the fortress. Ludwig nodded at Wang Wenyuan. Wang Wenyuan shouted loudly and excitedly: "Fill with hydrogen!" The flag bearer on one side waved the flag downward, and the ground crew below began to run over to inflate the airbags. Soon the airbags were full, and the airship began to shake. The buoyancy of the hydrogen bag kept the airship in an ascending state, but the airship was pulled by several thick ropes below. (The first airship inflatable from the outside in.) "Put the rope!" Wang Wenyuan gave an order, and the inflators began to retreat, and at the same time, the ground crew next to the huge cement pier began to nervously release the rope restraints.

"Fifty meters!" Wang Wenyuan looked at the huge white cloth strip on the rope and began to count.

"One hundred meters!"

"Two hundred meters!"

"Three hundred meters!"

"Four hundred meters!"

"Five hundred meters!" Wang Wenyuan shouted loudly.

Ludwig and Hu Xiaoyan did not move, but looked nervously at the ascending airship.

"A thousand meters!"

"Two thousand meters!" Ludwig and Wang Wenyuan's foreheads were already oozing with sweat.

"Two thousand five hundred meters!" Wang Wenyuan looked at Ludwig nervously. “

Three thousand meters! "Can't go up anymore!" Wang Wenyuan shouted.

Ludwig remained silent, but he was already sweating profusely. "It's almost all." Hu Xiaoyan couldn't hold on. Further up, the airship may fall apart! This era did not have as many strong and reliable aluminium as later generations. The main body of this airship is all wood, and only near the airbag is aluminum. Even so, the cost of this airship is at least 50,000 pounds.

"Stop! Turn on the lights! Ludwig didn't want to rise anymore, but Hu Xiaoyan didn't shout to stop, and he didn't dare to move. You know, the last time in Germany, the airship flew less than a thousand meters high.

Wang Wenyuan gestured downward. The ground crew who put the rope tightened the rope for the first time, and then fixed it on the cement pier. This huge cement pier weighs at least 500 kilograms and was specially built for the first airship liftoff experiment. A manual winch was installed on it. The ground crew below immediately started running. Many people are holding torches and lighting fires towards the pyre at the established location. Oiled pyre. The pyre was quickly burned. It's a "stop" word.

Hu Xiaoyan didn't know if the people on the airship could see this word, but they must understand what was going on. Because the rope underneath the airship was fixed, the airship stopped on its ascent.

The student technician and captain of the airship, Vanna, had long been frightened, this was the first time that the Germans had flown so high, and if something went wrong, even if there was a parachute, he believed that he would fall into the flesh. Finally, the airship shook suddenly, and the upward trend stopped.

"The auxiliary airbag slowly expels the hydrogen!" Varner calmly completed his mission despite his fear.

After the hydrogen of the auxiliary airbag is discharged, the inside will be filled with air, so that the buoyancy of the airship will be reduced, and the airship will fall.

"The airship is descending!" Ludwig saw several flashing bright spots in the sky where the airship was. It was the technician on the airship who was controlling the switch of the Davy light, sending the code to the command room below.

Varner calmly felt the vibration of the airship in the light of David's lamp, which was descending as planned.

"Two thousand five hundred meters!" Wang Wenyuan received a report from the ground staff. The ground crew determined the height of the airship by means of white cloth markings on the falling ropes.

"Two thousand meters!" Hu Xiaoyan looked at the black shadow in the black sky. Ludwig nodded and agreed. Hu Xiaoyan asked the airship to stay at an altitude of 2,000 meters, because the effective range of the Mauser rifle is 800 meters, but it does not mean that its maximum range is 800 meters. At an altitude of 2,000 meters, few rifles could hit it in this era.

As long as Hu Xiaoyan's airship can remain in the air at 2,000 meters, then his air force is invincible, and no weapon in this world can hit him. Of course, there are exceptions to those who are possessed by the gods or have the aura of the protagonist.

"Two thousand meters! Stop it! Ludwig shouted.

"Stop!" Wang Wenyuan commanded the ground crew to start extinguishing the fire. The word "stop" gradually lost its light.

"Commander! The lights on the ground are off. "The observation post reports to Vanna." Stop the operation of the auxiliary airbag immediately. Varner breathed a sigh of relief.

"Stop the work of the auxiliary airbag." The sound of the observation posts was heard one by one.

Soon the airship stopped descending.

"Turn on the lights! Overhaul the airship once again. Varner finally calmed down. He has already taken to the skies five times in Germany. This time the height was really higher than before, and he was a little nervous.

The lamp is, of course, a Davy lamp and is battery-powered. American production is dedicated to mining. Because at the moment there is no preparation and technology for installing a generator on an airship. At present, the lighting on the airship is all done by Davy lamps. But the Davy lamp is far from being lit for 24 hours and still working as usual like later generations, so it will only be lit when the work needs it. More than a hundred Davy lamps were installed on this airship.

As the German sound of the lights came out of the command room of the airship over and over again, the airship suddenly lit up. When viewed from the ground, it looks like several stars are hanging in the sky.

"There is no problem with the airbag body."

"There is no problem with the auxiliary airbag."

"There is no problem with the engine."

After a long time, another group of voices came: "There is no problem with the main body of the airship." ”

"Good." Varner wiped the cold sweat from her face.

"Start the engine!"

"Start the engine!" Orders were passed down by word of mouth.

"Start the engine!" The diesel technician started the engine. There are two engines, one gasoline and one diesel. They are all products customized for airships by the German company Daimler Automobiles, which were shipped from Germany only a few days ago.

This experiment was an empty airship, so two engines were installed for trial. The gasoline engine has been developed perfectly, and this experiment is mainly aimed at the diesel engine. It is well known that airships are faster than ordinary cruise ships, and large and super-large airships can carry a little more cargo than tankers. Therefore, it is the best choice to use a high-power diesel engine.

"The engine starts." Technician Charles calmly took out a notebook and began to record the engine starting, although when on the ground, Charles participated in the test of this diesel engine, and the diesel engine also performed very well. But then on the ground, and here it was 2,000 meters above the ground. No one knew that in such high skies, the diesel machine would not have problems, after all, this is the first time in history. It is also the first time that humans have reached a height of 2,000 meters.

Will I be remembered by history? Charles was distracted.

The start of a diesel engine is a little slower than that of a gasoline engine. But a loud rumble began to signal his presence.

"Collect!" Varner shouted nervously, it was all still planned, and the start of the diesel engine was the beginning of the airship test.

"Collect!" The guard walks up to the observation position and fires the Morse code of a David's lamp at the ground.

"Put the cable!" Ludwig quickly shouted. He had been involved in the design and experimentation of airships from the very beginning, and these simple Moorish codes, which did not need to be translated by anyone at all, had been in his heart for a long, long time. He also waited a long, long time.

"Put the cable!" Wang Wenyuan shouted in Chinese,

The ground crew on the ground began to run, telling the staff at the cement pier to release the cable.

Once the cable is released, the airship is completely free.

on the airship. "Rope recycling!" Feeling the vibration of the airship after it was free, the crew began to retrieve the cables.

Once the cable is recovered, the airship is truly free, it is no longer tethered to the ground! This is the first time that humans have built such a huge airship, soaring freely in the sky like a bird. In the first German experiment, because it was a small airship, it was not equipped with a gasoline or diesel engine, and its power was done by a dozen workers desperately pedaling on a flywheel like a bicycle.

And this airship will be powered entirely by diesel engines. Maybe Germany has done a similar experiment, but here is China!

"The diesel engine is working fine!" Charles felt it for a long time and finally breathed a sigh of relief.

"The diesel engine is working fine!" Varner finally put his mind at ease when he heard this. He began to feel the slight vibration of the airship. It's finally begun.

"Identify the direction and move towards the goal." Varner shouted.

The observation post picked up the binoculars and looked in the direction of the intended target. There was nothing there, which made him a little dumbfounded. Where is the target?
