The whole process of signing the confidentiality agreement was relatively smooth, on the one hand, because the people brought by Wang Hao were well prepared and explained the terms in detail; On the other hand, the people present now are the people who Yi Xuan personally audited very early, whether they are new or left by the old factory, they are all people who have passed the test in terms of technology and character.

Seeing that everyone signed it quickly, Yi Xuan and Qian Dongxu said a word, and asked them to start arranging the division of labor and officially starting work.

After the official start of construction, many people realized that they were taking it for granted, and it was not the materials that could float to build a ship that could float in the air.

This is because the steel used this time is different from the material that everyone has seen before.

After Yi Xuan finished the transformation, he thought for a long time about how to assemble these materials.

In order to keep the buoyancy sufficient, if the buoyancy level of all materials is increased to support 10,000 tons, then Yi Xuan has no choice but to build the factory in space.

Otherwise, the strong buoyancy will make these steel plates float, and they must be suppressed with a 10,000-ton object.

But if the buoyancy level of the material is too low, and the overall hull is built, it can't float, so what's the difference between building an ordinary ship?

So at the beginning, Qian Dongxu's team gave a plan to build a ship the size of a railway wagon car for experiments, so that the material does not need to have strong buoyancy, and dozens of tons of buoyancy can still be suppressed with the existing equipment, and then slowly try to increase the entire hull.

Although in the end, at least a floating train can be built, and the purpose of getting rid of roads and tracks can be achieved, but the capacity of a single ship is still not comparable to that of a 10,000-ton ship in the ocean.

In particular, Yi Xuan's ultimate goal is not this kind of unreliable transportation carrier with traction links, otherwise how can it operate in the interstellar in the future? Such a volume is too small.

In the future, Yi Xuan was preparing a huge spacecraft of the million-ton or even billion-ton class that could operate interstellarly, so Yi Xuan immediately rejected Qian Dongxu's plan.

Just when Qian Dongxu was very puzzled by Yi Xuan's decision, Yi Xuan immediately threw out a piece of information for him to see, and immediately dispelled Qian Dongxu's doubts.

It turns out that among the energy circuit technology that Yi Xuan researched in school, the use of gravitational circuit can solve this problem very well.

This way, you don't have to make a lot of buoyant materials from the beginning, you can use a lot of less buoyant materials with long strips or very strange shapes.

Sliding grooves are installed in the main load-bearing parts of the hull, and the energy circuits in these sliding grooves are driven by motors, and these components are controlled by different combinations and combinations distances.

Eventually, the combination of these energy circuits and the change of position generate forces in different directions, allowing the spacecraft to sail freely in the atmosphere.

Of course, because the spacecraft designed now is not fully enclosed, it cannot enter space for the time being, and as for entering space, it is also the goal that Yi Xuan wants to achieve in the future, but because he can't recruit relevant talents for the time being, he can only put it on hold for the time being.

After all, the creation of floating spaceships in the atmosphere has made Yi Xuan feel extremely lacking in relevant talents, but fortunately, Qian Dongxu has played a great role, otherwise it is estimated that everyone really doesn't know where to start now.

After so many strange materials appeared at the experimental site, many people thought that the cutting workshop had sent things to the wrong place.

But when we see that the various strange-shaped materials marked in the drawings need to be installed in various reserved chutes, we know that these accessories really need to be assembled.

Although in the end these parts were assembled, because they were not controlled to be combined through the chute, so everyone did not know the function of these parts, but continued to assemble the hull according to the drawings step by step.

Because Qian Dongxu uses the latest hull manufacturing technology, even though this ship is different from the ship that goes to sea, and there is no need to follow large accessories such as wheel propellers, he still decided to assemble the spacecraft in sections and finally weld it together as a whole.

Because of the emergence of Yi Xuan's energy circuit system, Qian Dongxu installed a corresponding gravitational loop system in the six main directions of the hull.

The hull is guaranteed to be able to navigate freely under all circumstances, especially since some backup gravitational loop systems are installed above the hull, so that even if the hull accidentally capsizes, it can float in the air and not crash.

Of course, these gravitational energy circuits are ultimately controlled by the main computer of the hull, and various instructions are analyzed and calculated through special management software to ensure the changes and opening and closing of various combinations of the hull in the state of floating and descending, turning left and right, moving forward and backward or capsizing.

And these designs, these assemblers will not understand, but they just think that these accessories are installed everywhere on the hull, and they just think it is strange.

This experimental ship Yi Xuan did not plan to build too exquisitely, but felt that he would put all the functions needed into practice and lay the foundation for mass production in the future.

As a result, in the manufacturing process, because of the error problem of blanking, most of the time is spent on the problem of welding joints, and the workload that could have been completed in one month often takes one more month to complete.

This also gave Yi Xuan a deeper understanding of the manufacturing level of the old factory in the past, and next, it is estimated that Li Dongliang will have to trouble Li Dongliang to dig people and buy equipment, or won't mass production be more headaches in the future?

Time passed quickly, and even if the interior decoration had been abandoned, it took nearly 6 months for the spacecraft that had only reached the basic navigation control capabilities to pass the preliminary review and be ready for experimental sailing.

For such a long time, all the engineers and technicians involved were already haggard, but they were still relieved to see the huge hull that had been built.

Because the hull is basically made of materials that change the gravitational properties, all the materials have their own buoyancy effect, although they are not large, but they are basically equivalent to losing gravity in the earth's gravitational field, so the hull as a whole is relatively light, basically the weight of some materials and equipment such as welding materials and electrical equipment that do not change the gravitational properties.

And these equipment and materials that are still affected by the earth's gravity and the volume of the entire hull are too small, so now such a huge hull is placed in the factory, and there is no need for any steel structure iron horse or track.

It was placed directly on the specially opened open space, and it did not crush the ground.

Of course, this is not the case of the load, if all the cargo is pulled, it is estimated that it will still need a track or a large iron horse dedicated landing field, or where there is no water, you need to keep the gravitational loop system on, or these weights must frackard the ground.

However, Yi Xuan thought that it was okay to keep these gravitational loops open, after all, the motors just controlled them together, after Yi Xuan designed a kind of card slot to help fix the various states of these gravitational loop components.

The overall control can distinguish various gears, basically as long as the motor hangs the gear, you don't need to care about him.

The only thing that needs to be changed repeatedly is only in the horizontal control, after all, the height of the float does not need to change too frequently, and in the horizontal direction, whether it is the various gears in the forward state, or the momentum control in the corner, it needs to be controlled frequently.

On the whole, this spacecraft only needs to be powered by the motors that control all the gravitational energy circuits, and even the rest of the living and working electricity that lives on it in the future, and the rest, whether it is forward power or floating power, basically does not need a separate power source, and the powerful field formed by the gravitational energy circuit is solved.

As long as the floating gravitational energy circuit component is stuck in one gear, the spacecraft can stay in the air for as long as it wants.

The gravitational energy circuit in the horizontal direction is different from the floating circuit, making full use of the various forces in the earth's astral gravitational field, and controlling the speed and angle of navigation by changing the magnitude of the forces of repulsion and attraction.

Because only the medium of air has resistance, it can be said that even if this kind of floating spacecraft uses the traditional diesel engine to propel by propeller, it will save a lot of energy output.

For the sake of cost savings, Yi Xuan did not plan to dismantle the traditional engine drive, but still used gravitational field power.

Therefore, the successful construction of this spaceship has initially realized Yi Xuan's dream, and it depends on whether it can be sold at a good price in the end.

As for this problem, Yi Xuan is not worried, those large shipping companies are estimated to be keen to buy this kind of ship, which will create another "Age of Discovery".

The experimental voyage of the new ship was finally scheduled for the evening, because during the day, an object of this size suddenly flew into the air, which was expected to mislead the average person.

For this experimental voyage, the entire Ark company can be described as a whole mobilization, except for those who make traditional orders.

The engineers spent a day testing the control of all gravitational energy circuits on the main control platform, and after confirming that they were correct, they repeatedly tested the status of each and carefully checked the installation and fastening of all accessories, which can be described as meticulous.

Yi Xuan can also experience the enthusiasm shown by everyone, because even when he understands all the principles and effects, he is also excited to see such a behemoth about to sail in the air, after all, this may be the same as the Wright brothers' first experimental aircraft, which will make the entire human race enter a new era.
