Chapter 487 (2/2)
I smile and say, ”of course. What am I going to do to build this guy
”Can we see the take-off effect?” Asked a president of the United States.I gestured to woma below, and she nodded.
Since the success of the thruster experiment, our guild has been working hard to follow the emerging aircraft, and the goal of course is to let us have the air fortress. But in the end, when the three technicians discussed for a long time, they came up with a design plan that was beyond most people's imagination. They made a strange thing that could not be related to the aircraft, and named it the big windmill.
This windmill looks like a huge beer barrel, and the structure of this guy is half wooden! In everyone's surprise, this giant beer barrel like object suddenly extends from one-third and two-thirds of the height with six giant blades. These blades are made of super light high-grade materials. The only drawback is that the price and performance are the same.
Suddenly, the two leaves began to move, but their rotation direction was completely opposite. With the rotation of these blades, the whole object actually slowly rose. When this thing rises to a high altitude, it suddenly begins to tilt eastward. When the tilt angle reaches 45 degrees, it suddenly begins to fall down. In the process of falling, it also moves rapidly toward the East. As the height drops, it suddenly begins to tilt backward, turning its bottom to the East, and then the speed begins to drop rapidly. When the horizontal movement is completely static, the barrel falls vertically It also began to slow down, and finally, as it approached the surface, it was completely stationary.
As everyone can see, this guy's trajectory is like a helicopter, but its shape is really ugly! In fact, there is a big gap between this thing and the principle of a helicopter, except that the flight attitude is somewhat similar!
”How did this thing fly?” The presidents asked excitedly.
I explained with a smile: ”there is a large gravity resistance device in the main body of that wine bottle. It actually relies on this anti gravity device when it lifts off, not the rotating blades. In fact, those blades are just starting. Because these blades only need to reach a certain speed to generate power, so they are already in operation when they are launched. When he reaches the approved height, the guy starts to tilt, pointing the bottom in the opposite direction. At this point, the gravity resister is turned off and the seven large air turbines inside it and the rotating blades on the outside are started at the same time. And then air is drawn in from the tail of the aircraft, and then air is ejected from the top of the turbine. Because the ”barrel” is inclined at this time, the lifting force will decompose. Part of the force will push it forward to make it move in the horizontal direction, while the other part of the force will hold the barrel to let it fall at a relatively slow speed, otherwise it will surely fall to the ground. As for the large rotating blades, they can also provide some lift, but in fact they are only equipment to help adjust the flight attitude
A slightly more knowledgeable German player immediately said: ”ziri president, don't be so stingy! I'm afraid the thruster can't reach this high thrust, can't it? You must have other equipment. After closing the gravity resistance device, the floating situation of that thing is very strange. It doesn't look like a complete propulsion flight equipment. You must have other technology. Please don't hide it. In the end, can we buy technology from you? ”
When he said this, other presidents met and asked me what kind of secret technology it was.
I said with a smile, ”actually, it's nothing to tell you. The president is right. It's impossible to support such a heavy weight by relying on the propulsion equipment. ”
”What kind of high-end technology do you use?” American players are always more excited.
I said with a smile, ”it's actually a very simple principle. I make a balloon.”
”Balloon?” After thinking about it for a long time, one of them suddenly asked, ”do you mean that some places in this thing are filled with ultra light gas such as helium, and they use the huge air buoyancy to pull up this huge object?”
”In fact, we didn't fill it in with helium. You know there are too many things needed to extract helium. It's not convenient in the game.”
”What did you rush in?”
”We didn't rush anything.”
At first, the German president looked at me in surprise: ”do you mean there are two vacuum chambers inside?”
”The vacuum chamber is lighter than helium, so it weighs less at the same volume.”
”But how do you do it?” Another German player asked, ”do you have a vacuum pump? What about support? If you want that thing to have enough lift, is the volume of the vacuum chamber too small? If the big thing is not strong enough, it will be flattened by atmospheric pressure, but if the shell is too thick, how can you solve it? ”
”With regard to stress, we find it easy to solve. We made it into a sphere, and then we built the shell of the ball with the strongest lightweight material we could find. When a certain pressure was applied to its surface, the pressure would be evenly distributed on the surface of the sphere, and then the pressure would further stabilize the molecular structure, thus generating enough resistance to the pressure. That is to say, the greater the pressure, the stronger it will be, and it will not be flattened at all. ”
”Negative pressure theory? The technical strength of your guild is very strong. You can make things of this principle level! ” The German then asked, ”but what about the vacuum? How do you make a vacuum? Ordinary air pumps can't draw vacuum, can't they? ””Of course we know that, but we have this one.” I pointed to the huge number of fire hydrants standing next to the square.
A guild president cried out: ”diffusion pump? You How did you do it? ”
”It was created by our guild tech players. It was originally designed to provide a vacuum environment for the vacuum fault detector. Now it's ready to use.”
Next to an American president, he asked the German president, ”what is a diffusion pump? Is it good? ”
Ashford answered for the president, ”the diffusion pump is a two-stage pump. It doesn't have much pumping capacity on its own, but once connected to the primary centrifugal pump, it can be used to create a high proportion of vacuum environment. There is a diffusion nozzle in its interior, which can eject the internal dispersant at high speed. After wrapping the air molecules, these dispersants will sink to the bottom of the gas chamber, and then the high-density molecules at the bottom will be pumped out by the primary pump, so that the air chamber becomes a vacuum environment. The principle is about this, but the specific manufacturing is extremely complex, not something that can be made casually
Those presidents all listen and take a breath.
Ashford said to me, ”what kind of dispersant are you using? That's not easy to do
I smile and stretch out a hand, and then fly from behind a few pieces of silver feathers, feathers into steel, silver bees fly to the top of my hand. These steel honeybees quickly turned into a ball of mercury above my hand, and then gathered more and more.
Now I don't have to explain it. Ashford himself sighed, ”so you can manipulate the magic mercury! It's strange, otherwise
A president at the back asked, ”how much is this? Can't we buy it yet? ”
Ashford helped me answer: ”unfortunately, I'm sorry to tell you that even if ziri president is willing to sell it, you can't buy it back. The dispersant needed by the diffusion pump is not easy to find in the game. The only easy to find is mercury, but it can't be used unless you can control it. The dispersant is easy to volatilize. It is very difficult to pour it into the diffusion pump. I don't think it can do without the ability of ziri president to do so! ”
There was a murmur below, all of which were saying that it was strange. Otherwise, I told them everything so generously that it turned out to be a technology that could not be imitated at all.
Red moon began to introduce to the presidents: ”although we can't sell the diffusion pump, we will start to sell the evacuated vacuum chamber in the future. I think you should be interested? Even if you can't build an aircraft, you can make a hot-air balloon or something like that! ”
When the Red Moon said that, the presidents around wanted to buy it. We quickly explained that there was no production line ready for the time being, and production could not start until the end of the battle.
After we had arranged all the things in the city, the fleet started to set out. As for the mobile fortress named windmill City, we didn't let it fly directly. The speed of that thing was not flattering. We're going to start the ship in the back of the ship, and we're going to pick up the ship. In this way, this big guy can not only catch up with our battle in time, but also reinforce our fleet by the way.
There is a cross-border transmission array in windmill city. We can go to the city at any time. So I didn't set out with the fleet. I could go through the transmission array when I needed to.
Windmill city is said to be a city, in fact, there is not much space. The barrel city itself is not very big. The vacuum tank occupies two-thirds of the space in the upper part of the city. In fact, only the bottom third of the city is available. The gravity resistant device was the size of two big buses, and none of the seven air turbines was inferior to the gravity resisting device, and as a result, they occupied most of the remaining one-third of the space. In addition, the energy extractor specially designed for these big guys is also a fantastic guy, and the remaining space has to be occupied again! At the end of the day, a huge transnational transmission array was to be placed in the remaining space. Therefore, our designers moved for a long time to free up an open space. However, the mobile city could not be without communication and lookout equipment. So we built a communication room and City Council hall, and also built an observation cabin to serve as the revival hall and domestic transmission array. In the end, there is still a little space left to be designed as a take-off deck, which is convenient for the air force coming out of the transmission array to take off. After all, our guild has a lot of flying regiments. Because there was no more space, the flying city had no self-defense weapons at all. However, there were several small channels around the transnational transmission array, which were specially used for bombing. It's OK to push the bombs out of the transmission array through this hole. In case of emergency, it can also serve as a personnel exit to relieve the pressure on the main take-off deck.
The windmill city is a temporary piece of work. Because there are many problems that can't be solved, we have to make do with it first. As a result, the product has become the current virtue. On the contrary, at least it is small enough to be towed by warships. This is also an advantage.
As the fleet sped through the sea, players in the city began to load their bodies with medicine. Once again, I asked Weina to keep a blessing spell for all the soldiers. Weina said that as the LORD God of the city, she had the obligation to bless us, but she could not give us constant blessing, but she added a 24-hour God's prayer to all of us. The priest's prayer is at most a few blessing effects, but God's prayer is another matter. Not only the players themselves, but also the magic pets and weapons are strengthened, which makes the eyes of foreign players straight.The players in Eisinger's communication room suddenly reported with a private chat: ”president, the fleet has reached the sea off Indonesia.”
This chapter is 7000, and there is one in the morning, which is not necessarily the length.
