"This ...... Can this float? ”

Everyone looked at a new ship designed by Li Yuanjing, and couldn't help but have doubts in their hearts.

This ship looks quite advanced, but it is too expensive, and it is all made of steel, what should I do if such a heavy ship sinks?

"Don't worry about whether you can float up, just design according to this idea!" Li Yuanjing waved his hand.

Of course, he knew that the ship would definitely float, although Li Yuanjing decided to design the ship himself.

But Li Yuanjing is not a professional shipbuilder after all, and a lot of professional knowledge is not clear.

And all he can offer is some advanced ideas.

The ship is 70 meters long and 13 meters wide, and is powered by two steam engines in an in-line array.

In terms of technology, the original power output has been improved, which used to be a steam engine driving a propeller, but now it is two linkages.

For the steam engine workshop, it is not difficult to solve their problem, it is nothing more than to cancel the linkage on a single steam engine, introduce the steam generated by the two steam engines to the same location, and then install the linkage here and use the power of the two to propel it.

Although it is not known how the power can be changed by doing this, at least it can be ensured that the power output of both propellers is the same.

The rest of the connecting rods were designed by the shipyard, which was originally one to one, but now it has become one to two.

This problem is not difficult to say, it is not easy to say that it is not simple, it is just a round roller, and this task is directly handed over to the carpenter to solve.

The carpenter's task is to carve different textures to ensure that the maximum power is provided, and at the same time the layout is the most reasonable, avoiding unnecessary friction and loss.

In addition, the design of the sealed cabin has been added, and all places below the waterline are designed with sealed cabins, which also makes the position below the waterline of the entire ship unable to be fully utilized.

Basically, except for the boiler room, there are sealed cabins everywhere else, and even the outside of the boiler room has a sealed cabin, but it is slightly smaller than other places.

Since Li Yuanjing has the absolute right to speak here, these designers, and even the entire captain, have to follow Li Yuanjing's instructions.

For a while, the construction speed of some other ships slowed down slightly, and more people were invested in the construction of this new warship.

Other designs have not yet been worked out, but this does not affect the laying of the keel.

The keel laying is no different from other ships, the only difference is that it was originally made of wood, but now it is made of steel.

With the development of the iron-smelting workshop in recent years, the technology has naturally improved, and soon three main keels that meet the requirements were made according to Li Yuanjing's requirements.

Needless to say, the role of the ship's keel is the core of the whole ship, without the support of these main keels, the ship will not last long and will be torn apart by the power of the sea.

And the keel is not to say that the harder the better, but to maintain the hardness at the same time, it needs to have a certain elasticity.

In this way, it took almost two months for the three huge keels, but in the meantime, the other keels and related designs were gradually completed.

Next, the construction of the new ship began to enter a slow construction progress.

Since all of them are steel structures, the most important thing is welding, which is a completely different concept from the construction of wooden boats, which are mainly bonded with a special glue, and then squeezed and spliced, and after a period of time, the planks will be tightly connected together.

There are grooves and buckles between the planks as supports, and the water point is determined after launching, and then a separate treatment is carried out, and then a layer of glue will be fully applied afterward, and it also needs to be constantly checked during the voyage, once there is water seepage, it must be dealt with immediately.

But the steel structure will not be able to use this set again, laying the keel or something is easy to say, what you want is the hardness, and the seepage is not in the scope of consideration for the time being.

But the simple welding method seems to be a little insufficient, and there is no need to think much about brazing or something, and the welding hardness cannot be reached at all.

So, the gang decided to give these splices another insurance, and at the same time came up with a strange way to solve this problem.

First of all, the horizontal and vertical keels are relied upon, the in-line keel is the most important, the width of a single one is nearly half a meter, and if it is not for the use of special equipment, this thing cannot be transported at all.

But the horizontal keel is not so big, and the size of each one is thicker than the arm, and the holes are left directly when making it, and it is enough to pass through these holes directly when installing.

These people made a special furnace, after the two keels were cross-positioned and passed through, the container was covered, and then melted molten steel of the same material was poured, and then heated up and down, front and back, left and right at the same time, the principle is to hope that through heating, these molten steel can be combined with the two keels, which is a kind of casting and welding.

The principle is borrowed from a means of weapon building, that is, the kind of blade is made of stainless steel and the back of the knife is wrought iron.

But the same material will be more combined.

In addition, it is the last safety set, and after smelting, the joints are sanded to make them smooth and flat, and if there are cracks on the top, they can be easily observed.

As for the insurance, it is a special requirement when making the keel, there are several reserved holes around each joint, and the principle of heating and compression is used to fix the connection of two finger-thick cable-stayed steel bars, so as to protect the connection from easy breakage.

Although he was a little too careful, Li Yuanjing still did not deny it, after all, there is nothing wrong with being careful, and the most important thing about the ship is the underwater part.

Maintaining a certain gap between the three keels can actually reduce the pressure to a certain extent.

The underwater part is very fine, but the water part is not so particular, anyway, the main stress point is not them, so these keels are reserved for a hole at every other height, and then the connection is reinforced in the same way.

Time has come to the end of the year in the blink of an eye, and Li Yuanjing, who has been busy for half a year, has just completed the laying of the keel, no, it cannot be said that the laying is completed, it can only be said that it is 90% completed.

It's fucked up when you think about it, because for various reasons, the steam engine must be installed before the keel is laid, and then the capping construction can be carried out.

Looking at the extra space, Li Yuanjing couldn't help but feel a little painful, he already knew that there were three special steam engines.

But just think about it, the steamship not only has space to get on it, but also has to carry enough fresh water and coal, which is a big consumer.

But now it doesn't matter anything, just wait for the New Year to install the steam engine, and then you can carry out the follow-up work.
