Zhang Yanzhi's words are like:

The math old man said to the math idiot - math is super easy!

Physics Lao Shi said to the physics idiot - physics pediatrics la!

The old man of chemistry said to the chemical idiot - chemistry is so interesting!

Immediately, the general flag and small flag officers of the navy in the cabin of 'Small Cargo No. 1' looked at each other.

In fact, this small cargo ship is really easy, really foolish, and really similar to the operation of bumper cars - the Ming Dynasty people should be easy to learn.

How the ship for fools operates (do not imitate, do not do it at your own risk):

Put the key in this place, twist it, and start;

The throttle is in the middle position, the propeller is not connected to the engine power, and the propeller stops;

Pull the throttle up, the propeller rotates forward, and the hull drives directly forward;

Pull the throttle down, the propeller reverses, and the hull reverses;

The rudder (steering wheel) can control the direction, and the limit of the rudder is 180 degrees;

Because the cockpit is at the stern of the bed, it can be steered with the bow as a reference;

"For novices like you, when you stop at the dock, just stop outside the dock—"

"Just work with the people at the dock to throw the rope and pull the boat in, so you don't hit it."

The above are all basic operations, except that the throttle is really no different from a bumper car, Zhang Yanzhi let them try it for the first time;

All 14 of them were dancing with their eyebrows and excited.

But the first time they piloted a fool cargo ship, there were still many mistakes and strange problems;

Fortunately, this fool boat was cheap and durable, and fortunately there were no reefs near the bay, and the water was deep enough not to run aground

By the time all 14 of them had practiced it, it was already late. Zhang Yanzhi personally took the helm and drove the boat back to the plank road in the sea.

Don't look at the simple operation now, but the navy is still a technical class!

Let them practice the basic operation for another week, and then they can get on the high-end goods;

The first is radar, and in recent years, even cars have been equipped with radar, let alone boats.

Truth be told, installing this thing these days is as easy as installing a searchlight-

Feed! Master! Please install it carefully!

How can you install a shiptop radar antenna with double-sided tape!?

Screw me hard!

After comprehensive consideration. Zhang Yanzhi did not hesitate to install Huaan brand marine radar KR-1338C on all ships:

Radar range 36 nautical miles (66.6km);

10-inch 32-bit true color LCD display, concise and easy;

With the radar, my mother will no longer have to worry about me driving the ship 'Titanic'!

With radar, my mother will no longer have to worry about me being ambushed by the enemy in naval battles!

With the radar, my mother will no longer have to worry about me not finding a target when I rob!

In short, with the radar, it's cute!

It's easier to dodge obstacles and adjust the direction of navigation, but won't it be fun to play 'kite-artillery warfare' in naval warfare in the future?

When Zhang Yanzhi checked out, he knew that this thing was simply cheap, only 10,000 soft sister coins / unit (Taobao sells it.) Don't hit me in the face, crackle -)

After the radar, it's time to navigate!

That's right! It's navigation!

Don't think that you can only navigate if you put satellites;

In fact, there is another way - radio station navigation.

In layman's terms, radio station navigation is to receive the signals sent by 3-4 fixed-position stations, and then calculate the data of these radio signals to obtain the position of the hull and aircraft relative to these fixed stations, and then adjust the direction and position of the hull and aircraft according to this data to achieve the purpose of navigation.

For example:

Hyundai, the cargo ship departed from Yangcheng and sailed to Sydney, Australia;

The ship's radio navigation system will receive the broadcasts of the 'Yangcheng Radio' and the 'Sydney Radio'. There is also a reference to the radio station 'Yanjing Radio';

Then the system will receive the time, phase, amplitude, and frequency data of the three radio broadcast signals;

Automatically calculate the distance X between the cargo ship and the 'Yangcheng Radio Station Transmission Tower' and the distance Y from the 'Sydney Radio Station Transmission Tower'. Distance Z from the 'Yenching Radio Transmitter' tower;

Then, the system is on the world map:

Take the Yangcheng radio station tower as the center point, and draw a circle with the distance X as the radius;

Take the Sydney radio tower as the center point, and draw a circle with the radius of the distance Y;

Take the transmission tower of Yanjing Radio Station as the center point, and draw a circle with the distance Z as the radius;

The circle of Yangcheng and the circle of Sydney and the circle of Yanjing, the three circles intersect at a 'point' on the map.

This 'point' is the position of the cargo ship.

The cargo ship was kept open. The system continuously calculates the real-time position of the cargo ship according to the X, Y, and Z data of the three stations, and gives the driver adjustment opinions to realize the navigation function.

Of course, these are just principles, and modern radio station navigation systems will complete the above operations automatically;

A radio station navigation system will only act like a car navigation, telling you how to go, how far you are from the target, and so on.

Beginning in the 20~30s of the 20th century. Radio direction finding is the only means of navigation in maritime aviation, and it is still used today.

In modern times, satellite navigation and radio station ranging are used as auxiliary means

At the same time, these future captains and first mates, the current chief flags and small flags, have all eaten the 'Three Corpse Brain Divine Pill', and they must all be included in the management of the Zixiao Divine Sect and abide by the confidentiality regulations.

In fact, to be honest, Zhang Yanzhi is not afraid of them leaking secrets;

Radar, radio station navigation system, they can use it.

But who will believe it?

Even if they stole it back, it would be useless, because they didn't have electricity, they didn't have everything to go with it;

The more advanced things are, the more inseparable they are from the cooperation of the entire modern industrial system

However, even if the Pinghai Navy applied the above two advanced technologies, it was only a clever navigational method;

The military capability is still too weak - after all, it still needs artillery!

Speaking of artillery, modern people have heard it, and it is estimated that they will jump out again and say that this is a technical job:

I can't play without long-term training and learning, or something

Zhang Yanzhi scoffed, there is no impossibility in these years, only whether the brain is open enough!

Next time, I'm going to do it like this, do it like that

While driving the boat, Zhang Yanzhi was thinking about the future development of the Pinghai Sea Army and even the Australian and Song Dynasty Water Army, and soon the boat was safely docked on the pontoon plank road;
