It is not that this procedure can be avoided if the theoretical knowledge is solid and the technology is advanced, even Germany and Japan, which were praised by the Chinese people as the most advanced industrial science and technology and the most craftsman spirit in later generations, have made this kind of low-level mistake.

A newly launched warship in Germany was actually crooked, because the center of gravity was not right, and a huge Japanese freighter was also dismantled into two sections shortly after it was launched and sank into the sea.

Yang Wenli was not a scientist in his previous life, let alone a scientist, but he knew the importance of quality, and the Chinese were not good at this, and he wanted to change this situation.

How to change? It is to work the manufacturing process and quality inspection, and to work hard, not just talk.

The ship model is relatively simple, at least it does not have a complex power system, and there are no naval guns or anything, they are replaced by some models, and with the efforts of the technical department, it was built in half a month, and the simulated pool is simpler, but it is a few pumps.

On this day, Yang Wenli personally participated in the experiment, the 1.5-ton ship model, people can not lift, pulled by four healthy horses, to the experimental site, and then hoisted into the pool by the tower crane.

The pool is not a wave first, you have to see if the ship model is crooked, not to mention, this water, it is indeed a little crooked, so Yang Wenli asked: "Liren, when you make the model, are you made it in equal proportions?" ”

"Your Majesty, it is definitely made in equal proportions, Wechen knows that this ship model is to be experimented, and it has a heavy responsibility, not an ornamental ship model, how dare Wechen be negligent, I am supervising the whole process."

"It's not your fault, it's the design is wrong, you quickly find out the reason, and then correct the ship model, and then do a simulated high-risk sea state experiment. If it's really okay, I'll report the detailed changes to me, and I'll have to change the blueprints. ”

"Yes!" Yang Liren bowed and promised.

There was a problem at the beginning, and Yang Wenli's joy just now was gone, he instructed Yang Liren a few words, and then turned around and left.

However, the tilt of this ship model is not large, which proves that there are no major problems and can be easily corrected.

When the real ship was built, there were more experiments, one of which also had a tilt test, which was to use heavy ballast, and to experiment in various places.

There are also mooring experiments, sea experiments, etc., these are all small experiments.

After that, the naval artillery experiment is to see if the naval gun is on the central axis, and then to see whether the naval gun will cause resonance and whether there is damage to the hull.

There is also the most important power system experiment, although there are no complex electronic devices, but all kinds of basic experiments have to be carried out, and they are all the same.

The experiments of the first ship type are particularly numerous and risky, and there is no need for so many experiments on the same series of frigates later.

By mid-October, the model had finally passed the experiment of simulating harsh sea conditions, which meant that the shape and center of gravity of the frigate were basically fine, and the hull could be built.

Because of the addition of a large amount of manpower, the shipyard also has several workshops, and the manufacture of workpieces and parts is carried out in the shipyard, and most of the workers in the technical department and the industrial zone are transferred to the shipyard to work, and the current shipbuilding is the focus.

Entering the manufacturing process, Yang Liren is the leader, and no one is more suitable than him, so he also became the first temporary director of the shipyard, of course! Yang Wenli also stayed in the shipyard the whole time, and he was always the big boss in charge.

It was already very cold in mid-October, some outdoor activities had stopped, only the indoor still did not affect the work, and the construction in the factory could be done using the sectional construction method, but there were no large flatbed trucks, and they could not be pulled into the dock to assemble after they were built.

What to do? In a short time, this problem can be solved with orbital transport, since the frigate is not large, only one and a half thousand tons in total, divided into three sections, each of which is only five hundred tons.

What kind of towing can be used is a big question? 500 tons is also not something that can be pulled by a horse, the main thing is that the horse cannot brake, and when it reaches a downhill slope, the hull will lose control.

"Liren, no matter what, the hull is built on the rails first, and there will always be a way."

"Your Majesty, how wide are the railroad tracks? What are the specifications of the rails? ”

"This is a freight rail, to be a little wider, it must be two meters five, and the rails must also be heavy-duty rails, weighing more than 100 kilograms per meter."

"Whoa! Wechen immediately went to the steel mill to customize. ”

Yang Wenli had already had the idea of building railroad tracks and trains around the island, and Yang Liren was his closest person, of course, he knew a lot about it, but he had not been free before, so he did not put it into practice.

Now there is no way, the cold weather in winter, the workers can only work in the warm workshop, and can not delay the shipbuilding period, forcing Yang Wenli to lay the rails in the shipyard first.

And because the hull is very large and heavy, the track is not good, and the track is light, so there is the perverted specification that Yang Wenli just said.

This is very different from the train track specifications of later generations, which is more than 50 centimeters wide, in fact, once Yang Wenli formulated this specification, the train track of the Far Eastern Kingdom in the future is this specification, because the train is not a small toy, it is a huge system engineering, and it will affect the whole body, not to change the wide track, and even the entire industrial system will have to be changed, which is difficult to change.

There is no doubt that the best tool for towing the hull is the train, but it is certainly not possible to redevelop the train, which is no less difficult than the corvette, if not more so.

However, the Far Eastern Kingdom also has a certain foundation, there are electric motors, there are power systems, and it is not difficult to build an electric locomotive.

Yang Wenli, who felt that time was pressing, immediately returned to his office in the industrial zone to start designing the world's first electric locomotive, no, it should not be called a locomotive, it should be a locomotive chassis.

Because of the lack of power of a single motor, only a distributed power system is adopted, which is simply a motor for each train wheel, and a braking system must also be used.

In this way, it is relatively simple, as long as the design of a train wheel is solved, it is equivalent to the power and braking system of the full train chassis system.

Fortunately, when the bicycle was developed in the past, the brake pad material was also developed, the motor was ready-made, and there were no special requirements for other materials, which showed that Yang Wenli did not want to re-develop materials and important parts, just design, the task was much lighter, and now the most difficult thing is the complex chassis system.

Yang Wenli is not alone, he has 150 designers, and most of the train chassis is repetitive, there are many people, and the design speed is also very fast.

There is still time, there are many workpieces and parts before the construction of the hull, and the segmented hull is not to be built on the chassis of the electric train, some even have to be made in the steel mill, such as some large plates, I-beams, etc., all need large rolling mills and large plate bending machines, and the I-beams must be welded with large equipment to ensure quality.
