Chapter 160 What is the pinnacle of the mechanical age

Even after the aircraft carrier completely outlawed the status of the battleship, the giant cannon of the large ship is still sought after by countless people, which has to be said to be quite interesting.

If iron and blood romance is too superficial, is there a deeper meaning and reason?

The answer is yes.

Because the life of the main gun of the Longshuo has been exhausted, it will sail into the dock in the near future to accept the maintenance work of replacing the inner bore of the gun barrel.

So now, several engineers and technicians are setting up ladders to investigate the ablation and wear inside the gun bore.

"...Exactly, depending on the number of powder packs used each time it fires, 200 to 400 kilograms of propellant will deflagrate in an instant, and 900 kilograms of shells will be pushed out by the gunpowder gas. Under the extrusion of 88 rifling lines, it rotates at high speed and flies out at a speed of more than 700 meters per second..."

When firing with a full charge, the inner wall of the gun bore bears an average of nearly three tons of pressure on an area of ​​[-] kilograms per square centimeter, which is the size of a thumbnail.

The entire triple turret weighs 340 tons, but the hydraulic mechanism can drive it to rotate half a circle in 1 minute.

As the first battleship to use a high-temperature and high-pressure steam turbine system, the working pressure of the boiler can reach [-] kilograms per square centimeter, and the steam superheater can increase the steam temperature to [-] degrees.

Eight boilers and four steam turbines can output more than 13 horsepower, allowing a battleship with a standard displacement of [-] tons to reach a speed of nearly [-] knots.

The length of the optical range finder is more than 11 meters. It cooperates with the complex mechanical shooting element calculation equipment, and can control nine cannons to accurately strike enemy ships dozens of miles away.

It can be said that the battleship is not only a symbol of naval warfare, but also a product of the combination of human belief, theory, technology, and organizational capabilities.

They are designed by the best talents and integrate the most advanced technology. They are the crystallization of wisdom and practice, and they are truly important weapons of the country.

"...Compared with the Americans, we have a lot of freedom in the design of this kind of capital ship, at least not restricted."

"Huh? How do you say it?"

Lin Xunzhen and Zhou Changfeng walked through the cabins and corridors, the former strolled like a stroll, while the latter was already dizzy by the extremely complicated internal "traffic".

How many cabins did you just go through?Where did you turn the corner?Why is everything so similar?

"Panama Canal." Lin Xunzhen, with an expression of "you don't know this", explained slowly: "After all, it was excavated manually, with limited width and depth, and the size of the lock is also placed there. 110 feet (33.53m). Therefore, the American battleship design scheme must strictly follow the limit, and the broadside must not exceed 32 meters."

"Oh, this, I thought it was something else."

This is essentially a matter of trade-offs. If the limit is exceeded, the battleship will not be able to travel between the Pacific Ocean and the Atlantic Ocean via the Panama Canal, and will have to go south to bypass the entire South America.

One can imagine what a waste of fuel and time that would be.

Maybe the rich and powerful Americans don't care about those oils, but the time for strategic deployment and deployment is hard to buy.

On the way to the conning tower of the bridge, Lin Xunzhen introduced the special features of the Longshuo to Zhou Changfeng.

"This ship is more like a test product of new technology. New boilers and turbines, new main guns, new anti-mine armor, um... even the flue and chimney arrangements are new."

There is only one Longshuo-class battleship, and there is no construction plan for the second ship. Obviously, the Ming Navy is unwilling to spend more budget to build a treaty-type battleship that is tied up in the past few years. On board the Longshuo, they regard her as a technology verification platform.

In this way, once the time of the naval treaty is over, it will be possible to build battleships with better overall performance without restraint.

The Longshuo is a ship with a long forecastle, a hyperbolic S-shaped bow, and a pointed stern.

Her power configuration is eight new high-temperature and high-pressure boilers, four steam turbines, and four-shaft propulsion. The normal maximum output power is 13.2 horsepower, and the maximum speed is 29.4 knots; the power can reach 14.4 horsepower during overload operation.

The main gun is a 400-type 46-inch (982㎜) triple mount, 770 times the diameter, the armor-piercing projectile weighs 15㎏, the muzzle velocity is 380m/s, the horizontal and vertical penetration is 30㎜ at 200㎞, and [-]㎜ at [-]㎞, which is not satisfactory. It can pose enough threats to Colorado-class battleships.

Zhou Changfeng, who was in the control tower, felt like a child who just started school, full of curiosity about everything.

The last time he was in Guangzhou, he hadn't entered the bridge. This time can be said to be the first time in his past life.

"What's this? It's such a big one." He pointed to a large freezer-like steel object next to him and asked.

Lin Xunzhen was flipping through a copy of the Artillery Almanac, and upon hearing the words, he replied casually, "Oh, that's the bombardment calculator, and the one next to it is the shooting calculator."

Every firing of the battleship's main guns must be recorded in a book, and that big book is called the Artillery Almanac.

Shelling calculator?It should be a mechanical computer, right?

To be honest, Zhou Changfeng thinks that this kind of purely mechanical computing equipment has a unique charm. This is the so-called steampunk beauty, right?

Seeing that he was very interested in it, Lin Xunzhen explained briefly.

"Establish a coordinate system on the plane, and solve the radial and tangential velocity components of the enemy ship relative to our ship. Manual calculation must be very slow. Using this is very fast, and the mechanical component solver and differential calculation gear can be done in a few seconds. Out."

"Then, to calculate the elevation angle of the main gun and the flight time of the shell in the air, to solve this problem, you need to use the integral calculator to calculate the integral."

"Okay, now that the flight time of the shell has been obtained, it is time to calculate the change in azimuth based on the measured speed and heading of the enemy ship. Divide the tangential speed by the distance to get the angular speed, and then calculate the integral to know the change of the enemy ship. position."

【Component Solver and Integral Calculator】

It can be said that mechanical computers are the pinnacle of human wisdom before the invention of electronic computers. These types of calculators were jointly designed by outstanding teachers and students from the Department of Mathematics and Mechanics of Suncheon University of Technology and Imperial Gezhi University.

The fire control system composed of them weighs several thousand kilograms, and the manufacturing cost exceeds 1000 yuan, which is more than [-] million yuan in future generations.

It is undoubtedly very time-consuming to visit such a maze-like steel fortress, but Zhou Changfeng, who is full of interest, is full of energy.

Since he had something to do, Lin Xunzhen asked a captain to take Zhou Changfeng to continue shopping, and said he would stay for dinner at night.

Oh?It is said that the navy is an aristocratic branch, and there are many nobles or descendants of the powerful on the capital ships of the Ming Dynasty Navy, so the food must be very luxurious, right?
Zhou Changfeng, who was thinking about the food, naturally agreed. He was very upset that he didn't even eat strawberries yesterday, and he wanted to have a big meal today to have a good time.

It is reasonable for us Chinese to pursue delicious food, right?

So Zhou Changfeng asked the captain generously: "By the way, how is the meal configuration of this ship?"

Apparently the latter misunderstood what he meant, he was slightly taken aback, and replied: "There is an officer's kitchen and two soldier's kitchens, refrigerators, peeling machines, rice washing machines, dishwashers... oh, and ice cream machines too. "

faint!I mean food!

　I found the gif diagram of the two component solvers and the integral calculator.
