Chapter 105: Airship Test Flight
At six o'clock in the morning on November 6, 1629, the sun had not yet jumped out of the sea, and the sky was only showing the white of the fish's belly, and the sky was mixed with many banded clouds. Pen? Interesting? Pavilion wWw. biquge。 infoThere are many veterans gathered at the airport of Vostochny Port, all of whom were invited to watch the test flight of the airship.
This airship is not the large airship that Yuan Zhenli asked to build some time ago, but just a small airship, the length of this airship is about 100 meters, the width is not more than 10 meters, and the height is 12 meters, the whole airship is a huge spinning cone, the front end is relatively hypertrophied, and the tail is more slender, and the tail also has a tail for stabilizing the flight attitude and a rudder to control the direction.
The whole airship is covered with a canvas shell to protect the safety of the airbags inside the airship, but the canvas color is more peculiar, because many of these canvases are taken directly from the production line of the textile factory, so the colors are different, the only thing that is the same is that the size is almost the same. In order to meet the needs of various customers, the textile factory produces a variety of canvas colors, almost any color, red, blue, green and bright yellow, of course, the main color of the whole airship is still the kind of white canvas with a pale yellow.
Seeing this airship that was still located in the airship construction dock, the venomous tongue patriarch immediately commented there that the shape of this airship was really not good. In fact, to be honest, no one paid attention to the shape of the airship when skinning the outside of the airship at that time, and the airship skin at this moment was like the tattered clothes worn by Hanako and the feeling of being covered in patches, which immediately made the deterrent power of the airship itself completely gone.
The airship was still parked in the construction dock, and the naturalized workers were busy making the final preparations, and in front of this huge airship, people were as small as ants, and if anyone could look down from a high place, it felt as if many ants were busy around a Zhizhi.
"The auspicious time has come!" There was a patriarch next to him who shouted loudly, and the patriarchs around him looked at him in amazement, saying that the patriarchs who crossed over from the old world almost did not believe in the auspicious days, and at this moment, the patriarch suddenly shouted such a sentence, which inevitably made the people next to him too sideways.
When the patriarch saw that everyone was looking over, he just smiled and pointed to the side of the airship. Sure enough, the naturalized migrant workers next to the airship had already begun to descend from the hatch at the stern of the airship, and the personnel on both sides pulled the cable.
The controller in the airship looked at Yuan Zhenli, Yuan Zhenli took a few deep breaths and nodded at him. The naturalized people in charge of control hurriedly saluted, and then unscrewed the valve of the hydrogen tank.
There are a total of six airbags inside the airship, two at the front, three at the mid-end, and one at the tail. Although there are materials in the large library of the Senate, building an airship is still a matter that needs to be explored for a long time, and it cannot be achieved overnight. Even if the airbag has been tested many times at the beginning of the installation to ensure that there is no air leakage, but whether it is the veterans who operate and command in the airship or the veterans who are watching outside, their hearts are like pressing a stone at this moment, and the lessons of the Hindenburg are still there, if it really catches fire during operation, then it is estimated that the entire airship construction dock can be burned clean with the airship and the crew inside.
As a large amount of hydrogen poured into the airbags, the hull of the airship made a sound of steel being squeezed, which made everyone present feel a little creepy. However, Yuan Zhenli waved his hand and comforted the naturalized people in front of him, "It's okay, this is a normal phenomenon." ”
This is indeed a normal phenomenon, the airbag will start to float upwards after inflation, and the huge buoyancy will make the multiple connection points between the hull and the airbag be pulled by a huge force, so it will make a sound. Because these parts are very important stress points, they have been specially inspected before being put into use to ensure that each part can withstand more than three times the force of the tensile force at the moment before it can pass the acceptance and be put into use. Therefore, Yuan Zhenli didn't have much concern about these voices themselves, the only thing he was worried about was the elders who were watching the ceremony in the construction dock - there were even smokers in these guys!
Yuan Zhenli is not a non-smoking character, but he can also distinguish the situation at the moment, smoking in an airship full of hydrogen, which is even more life-threatening than the old birthday star eating arsenic. You must know that at this moment, in order to prevent sparks, not only is no one allowed to smoke or bring fire, but even the radio used by the airship is grounded. In order to prevent the airship from gathering static electricity when flying in the air, a long large iron chain is specially left at the tail of the airship away from the airbag, and the chain will be lowered to the ground before landing, releasing the static electricity on the airship to prevent fire.
But it's not so scary now, the content of hydrogen in the atmosphere is also there, and now even if it diffuses, it won't catch fire when it encounters Mars, but it's still necessary to take precautions, isn't it?
At this moment, Yuan Zhenli was carrying a parachute bag, and several naturalized people around him were also carrying this thing. These parachutes were produced in this plane, and the material used was silk - all of them were bought from the Wu Dynasty, and even if they could make canvas, the demand for silk was still very huge, so the Medeno people would still bring silk in large quantities as trade materials.
These silk parachutes were produced in recent months due to the unsuccessful operation of using the Mosquito to airdrop ** to the Kitagami detachment a few months ago - two of the cargo parachutes brought by the three old planes were not opened. This made Yuan Zhenli decide to disarm all the parachutes he brought, just kidding, originally using parachutes was to ensure the safety of personnel, but with such a parachute, it is too terrible to be able to reach more than 60% of the non-parachute rate, it is better not to carry it. Therefore, the Air Force purchased a lot of silk and established a small factory near the airport to produce the Air Force equipment in the New World, of which the parachute was the first important production item.
These parachutes have undergone complex quality checks and many airdrop experiments before equipping the Air Force, of course, they cannot fly into the sky with an umbrella bag to jump down every time, a 90-meter-high tower was built next to the airport - the height of this tower is even higher than the square tower in the Haichao Temple not far away, and every day the Air Force testers tie the parachute bag to various heavy objects and throw it down from this parachute tower to check the opening rate.
As more and more hydrogen gas entered the airbag, the airship slowly left the fixed slide rail on the ground, and the personnel on both sides held on to the cable tightly, and walked towards the slowly opening gate under the command of Yuan Zhenli. The sun had just risen, and the sunlight reflected on one side of the wall of the construction dock, illuminating the entire construction dock. The elders present all held their breath and watched nervously as the airship slowly slid towards the gate of the dock.
The airship is different from the airplane, it is actually more similar to the submarine, by changing its own internal filling to meet the needs of flight, it does not use the propeller to generate lift off the ground, its lift comes from the hydrogen in the airbag.
As the airship completely left the construction dock, it was dragged by many naturalized people to the runway of the airport, followed by a large group of veterans, which was not lively enough. The amount of hydrogen injected into the airship at this time was already very large, and the tow rope in the hands of the naturalized people was tight at the moment.
"Isn't that a joke?" Li Zhe muttered to himself there, "The airship itself doesn't need much buoyancy, as long as it can remain suspended, it doesn't need to rise by lift." ”
Indeed, it is enough for the airship itself to maintain a critical value close to suspension, and the amount of hydrogen in its air bag must be adjusted through a regulating valve to prevent excessive hydrogen production. You must know that the higher you go, the thinner the air becomes, and when the hydrogen inside begins to expand, it is likely to directly burst the airbag, and then you can only let the airship crash. In addition, the airship also has a troublesome thing is the sun, the sun will continuously project heat to the earth, and the airship will naturally be heated when it flies in the air. The effect of thermal expansion of the gas is the most obvious, as can be seen from the Stirling engine used in the truck, at the moment the airbag is hydrogen with a very high thermal expansion effect, so it is more cumbersome. In fact, Li Zhe sent an email to Yuan Zhenli in this situation, but looking at this situation at the moment, it seems that Yuan Zhenli didn't take this situation to heart at all. As the bronze bell hanging at the front of the airship struck and the naturalized people on both sides released the towing cable, the airship immediately began to rise.
"Wow!" With the unison of exclamations from outside the airport, the veterans, who had focused on the airship at first, were startled, and looked around, and it turned out that there were thousands of children standing densely outside the barbed wire fence of the airport at some point. This situation amazed the elders present, "When did there be so many students in Oriental Harbor?" ”
That's right, these children are all students of Dongfanggang School, and since the matter of the airship sailing to watch the ceremony is not kept secret from the senators in the Senate, Jiang Yan also knows about it. After she learned about this, she couldn't help but be excited, and asked Li Zhe at that time whether to call all the children of Dongfanggang School to watch the airship. Li Zhe almost didn't jump up when he heard it, joking, although this matter is not secret to the patriarch, but there is still a level of secrecy for the naturalized people, if this is brought over thousands of children in an uproar, what will happen if it is not guaranteed.
However, Jiang Yan did not give up at all, she arrived at the school and discussed it with Wu Fang and many education elders for a long time, and finally unanimously decided that this matter should be seen by the students of Dongfang Port, and even some naturalized people who are teachers here are also necessary to take a look. You must know that these naturalized people in this time and space are always remembered by heart, but they are disdainful of all things in nature, and they basically completely ignore mathematics, physics and chemistry. The Senate has black technology, but it can't be shown in front of them, and the only thing that can stop them before is the steel giant ship Dongfeng, but it is no longer anchored in Dongfang Port at this moment. Now that the airship has been built, it will be tested tomorrow, which is a great opportunity for these naturalized people and children to broaden their horizons. For this matter, a group of veterans from the education department specially went to the executive committee and soaked it for several hours, so that the executive committee had to relax and let the children go outside the airport to see, but they were absolutely not allowed to enter the military restricted area.
Lu Dan and Lu Yu stood in front of the barbed wire, staring closely at the airship that was slowly rising in the sky, and between them stood Lu Hua, and the three children were holding hands at the moment. For them, the most shocking thing they have ever seen before is nothing more than a steel giant ship, although a teacher has taught it during class, saying that as long as the buoyancy is reached, even bricks can float on water. But how can this huge airship, which is in the air, ascend to the sky?
All the children present were like them, full of infinite reverie about this slowly rising airship, and the people of this time and space did not conquer the sky. You must know that the pilots wearing the winged badges of the Chinese Air Force will be watched by naturalized citizens every time they go out, and many people will ask if they will see the heavenly soldiers and generals when they fly in the sky, and whether they will see the pavilions and pavilions of the heavenly court on the top of the clouds. Such a problem is not only a pilot, but even an ordinary ground soldier.
"It's unbelievable that something so huge and bulky can fly off the ground, isn't it?" Xu Xiake looked up at the floating airship at this time, since entering the Oriental Port, he was the first time to come into contact with so many detailed geographical information and all kinds of knowledge, it can be said that everything from astronomy to geography is all-encompassing, although occasionally I have seen a scale and half claw about the airship in some articles, but at this moment I saw a real airship slowly rising in the sky, such a shock has completely broken his worldview.
Different from the hot air balloon equipped before, although the hot air balloon has some simple advantages when preparing for take-off or operation, its controllability during flight is basically zero, basically the wind blows wherever it goes, unless it is tied to a fixed cable, otherwise a gust of wind will blow away. The use of cables is not completely without danger, some time ago a hot air balloon used for observation suddenly broke when the gondola was in use, and the two naturalized people in the gondola fell directly to the ground of dozens of meters and fell directly to their deaths. It was the occurrence of this accident that strengthened the Senate to devote itself to the development of the construction of airships. Not only does the airship have controlled valves to ensure the hydrogen concentration in the airbags, but also two diesel engines to provide power during flight, allowing it to maintain its speed in the air, and the propellers are also variable angle, allowing the airship to adjust its attitude and altitude in real time while the airship remains suspended. The total weight of this airship is about 30 tons, and due to the extensive use of steel structure, the weight has been reduced a lot, and the load can reach 5 tons. Its construction was originally used as a training airship, and it was built in a hurry at the moment, and its main function was to bring back the northbound detachment.
