For hundreds of years, the design of ships has changed little, only in shape, with the exception of the groundbreaking bulbous bow design, of course.

Taking the unique Fu ship of the Ming Dynasty as an example, there is a segmented combined keel and an anti-sinking compartment design, which are inherited by modern ships.

Moreover, ancient wooden sailing ships had to withstand huge stresses because of the sails that served as a power source, but the design was more complex and stronger.

The 400-material warship of the Far Eastern Kingdom Navy is a typical Fu ship, and Yang Wenli simplified the design of the structure of the Fu ship, but in fact, the technical difficulty is not great.

The flying scissor bow can cut the waves and significantly increase the speed of the ship.

The floating hull can significantly increase the stability of the ship and reduce the resistance of the seawater, and this good ship design idea should also be inherited.

Under modern ships, there is a cylindrical load tank shaped like a submarine, which lowers the center of gravity of the ship and improves the stability and wave resistance of the ship.

There is also a square stern, which better arranges the power system and further increases the stability of the ship, which is a good method that is also inherited as a whole.

It should be said that this is already the general shape of the beautiful modern ship, but this is not enough, Yang Wenli also has his own unique creativity, he found that the two ribs of the submarine in later generations have short balance wings similar to the wing, this short balance wing, in the harsh environment of high wind and waves, has the same stabilizing effect as the needle of the sea, I don't know why the ships of later generations did not use? Is it the reason for the reduction in the speed of the ship? Probably not.

The front eaves of the balance wing, which can be designed as a streamlined parabola, should increase the drag very limited, but if properly designed, it can not only increase the stability of the ship, but also significantly increase the buoyancy and thus the speed of the ship.

The principle is the same as the principle of wing lift of the aircraft, further raising the bow of the ship, so that the ship is similar to the sea-skimming flight, just like the principle of high-speed motorboats, the purpose can be achieved by adjusting the short balance wing, slightly tilting up to raise the bow, flatten the bow to lower.

Of course, the idea is good, and it will take a lot of experiments to sum up the experience in order to finally achieve the desired result, but Yang Wenli has already decided to add a pair of short wings to his new frigate.

Because of the different historical eras, the combat objects of warships are also different, and the upper part of the frigate designed by Yang Wenli is quite different.

First of all, because his opponents are very weak, then the upper part of the ship can be relatively one layer or two layers, and the area of the bullet is increased, and it is not afraid that others can hit it.

The purpose of this is to combine the functions of the frigate and the landing ship into one, which can carry more soldiers, and Yang Wenli initially estimated that each frigate can carry an additional car of soldiers, about 1,400 people.

On the other hand, because there is no advanced radar electronics, this new type of frigate also needs manual early warning, that is, it also needs a lookout to stand at the height of the mast to lookout.

Because it is a new-type power ship with good conditions, of course, it is impossible to be the same as the lookout of the Xiyi people, sitting in a simple wooden bucket at the top of the mast, blowing a strong sea breeze, and there is no place to hide from the rain on rainy days, and the bad sea conditions with strong winds and waves can only tie themselves to the mast with a rope, and if they are not careful, they will be blown away by the sea breeze.

Everyone should have seen the tower crane on the construction site, there is an operation room on the top of the tower crane, three sides are glass, the view is good, because it is too hot in summer, and it is also equipped with air conditioning.

Yang Wenli borrowed this design, but because of the strong sea breeze, he designed the observation deck as a bullet-shaped cabin with a streamlined slope in front.

In order to further improve the field of vision, in addition to the necessary internal support columns, there are full-view glass on three sides, a built-in leisure chair that can be rotated 360 degrees at will, and it is also equipped with air conditioning, as well as drinking facilities, urinal troughs, and binoculars, so that the lookout can stay on it for a day if he brings enough food.

There are telephones in there that talk to the command module, huh...... Of course, it is a primitive pipe-type intercom, and there is a modern alarm button, which really has an electric bell, if the enemy situation is found to be serious, you can press the alarm to warn the whole ship.

Yang Wenli is a modern person, and his design ideas have modern thinking, and everything is beautiful, which can be regarded as a beauty control, and of course there are some fluid mechanics factors in it.

The superstructure of the frigate also has a backward slope windward side like a yacht, and between each floor, there is a balcony part, and the side side is a stealth integrated design that is slightly inclined inward, and the aisle is located in the middle of the cabin instead of a straight passage.

The appearance of the entire hull is like this, like a stealth frigate of later generations, without a large area of uprightness, and basically made an inclined or cut design.

There are three decks on deck, the top one is the command cabin, the cockpit, the training cabin and the canteen, because the upper level has direct sunlight and is too hot to be used as a crew cabin.

The lower two floors are pure crew cabins, which occupy more than half of the upper deck because there are no huge chimneys, and on either side of the long passage are brightly lit luxury cabins.

Because there is only one twin 76mm naval gun on the front and rear decks, the volume is not large, so in order not to waste, Yang Wenli made this unique design, like a yacht more than like a warship.

Because this kind of 1,500-ton frigate can only be equipped with one steam turbine power system, even with the addition of coal tanks, one layer of cabins is enough, so below deck, there are two layers of cabins that can carry people.

Of course, it is not so luxurious configuration, it is a mixed type of people and goods, not a special cabin, the most important thing is the cargo hold, as the weapons and equipment of the army and the logistics supply and transportation, but when there are many people, hanging a hammock can also carry people.

In order to speed up the process, Yang Wenli also brought a design team, and he divided the hull into several independent parts, and split them into their respective responsible parts, some responsible for cabin design, and some responsible for bilge design.

Fortunately, it was the season of heavy snow and freezing, and there was nothing else to do except do scientific research indoors, so Yang Wenli could concentrate on designing the hull.

"Everyone should pay attention to the use of materials, in addition to the periphery and support stress parts, the rest of the secondary parts, try to use lightweight materials.

Even the waterproof compartment at the bottom is the same, in this era, no one can blast through the shell of this new type of ship of our army, so the internal isolation layer can be made of thin steel plates, the bottom deck, etc., must be made of thin steel plates, in short, try to reduce the weight of the hull. ”

Yang Wenli is like a design director, reminding them from time to time, he shuttles around each designer, solves problems for them, and corrects their mistakes from time to time.
