Chapter 1071: "·Roman Battleship"

Only when you are hungry, eating is beneficial and harmless. Similarly, only when you are loving, dealing with people will be beneficial and harmless.
-Lev Nikolayevich Tolstoy (one of the most outstanding writers in the history of world literature)
After figuring out the truth of the three big and imperial general warships of Xiaozao, Shuanchuan and Anzhai, Nams had a slight sense of nervousness and completely relaxed; in his view, the warships of the Yamato Empire were simply It is the lamb to be slaughtered to send his fleet record!
You know, the first fleet of Rome under Namus, in addition to the flagship is the seven-tier battleship Big Mac, "Empire", there are a full of twenty double-row battleships and thirty three-tier battleships; double-row battleships and three The combat power of battleships is comparable to that of the imperial ship.
Nams, a Roman naval general, was never a self-esteemed arrogant, and he was not an inferior humble person; his self-confidence in his fleet and contempt for the Yamato Imperial warship came from the Roman superb. Shipbuilding technology.
The most common double-row battleships and three-row battleships in the Roman battleships, also known as two-layer paddle battleships and three-layer paddle battleships, its predecessor was the more primitive single-layer paddle battleship, each battleship had one layer of paddles, and the ship There are twenty-five paddles on each side.
With the improvement of Roman shipbuilding technology, the ship became larger and larger, so the oarsmen were divided into two or three layers to accommodate more oarsmen to provide greater power to the battleship; compared to the simpler structure Two-layer paddle warships, the slightly complicated three-paddle warships are staggered on one side of the paddlers, the third layer of paddlers are above the deck, and the first, second and second layer of paddlers are located on the deck. under.
Later, the battleship continued to increase, and it was difficult for a single oar to paddle a large oar, so a five-paddle warship appeared. The paddlers of the bottom layer each paddled one oar. When a person slides a paddle, a total of five layers of paddlers paddle three layers of paddles; because of the more complex hull structure of the five-layer paddle warship, all the paddlers on the battleship are below the deck.
No matter how many levels the oarsmen sit on, the total number of oarsmen in the upper and lower rows has always been a symbol of the size of the warships; therefore, there is a division of double-row battleships, three-row battleships, five-row battleships, and even seven-row battleships. , And Skycrow is another kind of battleship.
One can clearly see from the design of the two-row battleship and the three-row battleship that one of the main problems faced by designers of this typical Roman battleship is to avoid overweight the upper part of the battleship; determine whether the battleship is stable and whether it can These conditions that restore stability on their own when leaning often need to be considered according to the stable height of the warship.
Regarding this concept, although the Romans did not systematically establish the physics and mathematics system, they already knew most of the basic concepts of physics and mathematics; the smart Romans knew that the warship was like it was started The weight is concentrated to a certain point, and it is pulled down to the center of the earth by gravity.
For example, if the battleship is tilted to one side and the hull immersed in the water is small, the center of gravity of the part will move in the same direction; the buoyancy of the water will act through the center of gravity of the part immersed in the water, pushing vertically; The part of the center of mass immersed in the water is fully moved in the inclined direction, then its upwardly acting buoyancy force is offset by transferring downwardly acting gravity to the lower side of the hull.
The final effect of the two forces working together will make the battleship recover on its own. The stabilization height of the battleship is the distance between the center of mass and buoyancy and the intersection of the ship's centerline; this means that the greater the stabilization height The more stable the structure of the battleship.
The warships designed and built according to these professional knowledge, their combat power naturally cannot be underestimated. Take the three-row battleships that generally serve as the main force of the Roman fleet as an example; the typical three-row battleship has a total length of 37 meters and is equipped with three layers. Hundreds of oarsmen, with a length of four meters and a total weight of 45 tons, can continuously sail for about 200 nautical miles at a speed of nearly eight knots (depending on the freshwater and food on the battleship).
There are three battleships with only one hundred oarsmen. The reason why the crew is full is 120. That's because there are 20 professional sailors on board; their duties are sailors and helmsmen. , Lookouts, etc., the status is higher than the paddlers.
With sufficient knowledge about the size of the three battleships, the crew composition of the battleships, and the freshwater equipment on the battleships, you can estimate the stable height of the battleships and adjust the structure of the battleships.
The numbers obtained by the Romans regarding the warship’s draught, the amount of wood used for the warship, and the layout of the paddlers in the warship are susceptible to changes in assumptions; even when there is a slight change in one or more of these factors, This can lead to a five-kilometre or six-kilometre change in the wind, which can cause the warship to capsize.
However, as long as the parameters of various types of ships are kept unchanged, the ratio between the stability values ​​will be correct, even if the two values ​​are not absolutely correct, because this method is correct; therefore, the Romans It will be assumed that the hull and contents of the transition from three-tier battleships to four-tier battleships or five-tier battleships can be changed as little as possible.
Since the evolution of shipbuilding technology is extremely slow and requires a long time to accumulate, this assumption seems entirely possible; but the most unestimable in this analysis is the amount of ballast the ship bears, because the double-row battleship has enough The hull space to accommodate enough ballast to make considerable changes to the smooth characteristics of the hull.
In estimating the ballast, the Romans were willing to keep the hull as light as possible, and to coordinate with other obvious efforts made by the hull assembler of the double-row battleship, that is, the hull manufactured should be matched with the oar to the greatest extent. The strength of the hands; the estimated ballast is 13,000 kilograms. This weight is sufficient to prevent winds of less than 60 kilometers per hour from blowing on the two ends of the hull beam to blow down the battleship.
This obviously unsatisfactory situation shows that the shipbuilder modified his hull design under heavy pressure; from the reasons already mentioned, the only good option for the shipbuilder to consider is Increase the maximum width of their ship's hull.
However, this approach must sacrifice some speed, which is the main reason to design a warship with a larger number of layers first; for the five-tier battleship, if the hull is widened to equal the three-tier battleship for stability The width of the hull, its speed can only be 14% faster than that of the three battleships, and its acceleration is worse.
If 62 paddlers are added to the top layer and 54 are added to the middle layer, then the size of the crew will increase by nearly 70%; and if the stability of the five-tier battleship is reduced to what was previously envisaged, its increased speed Up to 29%.
The three battleships in Rome are powered by the oarsmen in the oars, and the sails are only auxiliary powers. It is worth noting that these oarsmen are not prisoners of war or slaves, and the employer must pay the high compensation they deserve. The fighter's remuneration is quite high, which is why, after recruiting battleships, Bai Feng still has to pay maintenance fees to Roman battleships like other conventional Roman arms.
The three-row warships built on these advanced designs can carry all far-reaching weapons and can directly collide with enemy ships without damage; the more advanced five-row warships and seven-row warships are loaded with large bows Weapons, and other shooting equipment!
