Section 21 A ketch that combines ancient and modern Chinese and Western styles (2)
In terms of armament, an exposed turret is installed at the bow and stern of the ship, each with a 70mm rifled cannon. A retractable tarpaulin frame is installed above the exposed turret, which can be covered to protect the artillery. It and the artillery trial production team headed by Lin Shenhe
The exposed turret installed on the fishing boat has the same structure. The only improvement is that the rear seat system of the retractable gun mount has been changed from the original pulley group + cable system to a rail-mounted gun mount - the gun mount is installed on the wheel sliding
On the track, the recoil of the artillery is offset by sliding along the track when firing. The end of the track is a hardwood blocking block. The collision and rebound force between the wheels and the blocking block are used to push the artillery back to its original position - no steel is used.
It is to prevent the collision between the two from sparks. If the traverser's mechanical level is better, Lin Shenhe can introduce more complex gears, rollers and hydraulic systems to achieve a better buffering effect - after all, on a warship,
The weight and volume restrictions to solve the artillery's recoil problem are much looser.
This system has already undergone preliminary testing on the Lingaojiao Fort and is considered to basically meet the needs. Its installation on the No. 0 ship also includes the intention of testing it at sea.
The artillery position is rotary, and the rotation is driven by manpower below the deck. In order to facilitate the gunner to guide the rotation angle, a communication tube is installed on the gun position. The 90 degrees pointing to the deck are limited to prevent the enemy from jumping to control the artillery.
It is used to design the deck and prevent gunners from misoperation.
Although the protection of the exposed turret is not very good, there is no artillery in this time and space that can surpass the range of the 70mm rifled gun. The gun profile is riveted with rolled iron plates, and the defensive power is quite impressive according to the standards of this time and space.
According to the ideas of Wen Desi and the navy, they also wanted to lay a rolled wrought iron armor plate on the deck of the "Zero" to build the first dome-armored cruiser, but they did not plan to install this deck.
After the required number of wrought iron plates was reached, Wen Desi gave up the idea, and finally just installed armored belts around the ammunition chamber as a kind of safety protection.
In terms of auxiliary weapons, Li Yunxing's idea was to make multi-barreled guns, but this thing was bulky and slow to load. In the end, mature technology was used according to Lin Shenhe's suggestion: six 2-pound light mortars were installed: two on the side of the ship.
There is one gun on each side, bow and stern of the ship. The other two guns are to be installed on the platform at the top of the mast. This kind of artillery is very small and is installed on a freely rotating gimbal. It can rotate 360 degrees and the elevation angle can reach 80 degrees.
, the depression angle also reaches 40 degrees. It fires iron sand, broken iron and shotshells with a total weight of no more than 1 kilogram. The range is very short, and its function is similar to the 12.7mm high-altitude aircraft on modern warships. It is specially used to kill enemies at close range. In naval battles, it
It is often used to shoot at the opponent's rigging and sailors on the deck. When necessary, it can also be used directly to clean up the jump gangs who have boarded one's own deck. Of course, the guiding ideology of crossing the navy is to shoot from as far away as possible, rather than exhausting the enemy.
, a close-range bombardment with heavy casualties.
Since the No. 0 ship is not going to install side guns, its available space under the deck is much larger, which greatly improves the ship's self-sustainability and carrying capacity. The living conditions of the crew are naturally much better than those of ordinary sail warships: more
There are more crew rooms and sanitary facilities, better lighting and ventilation, and Wen Desi has prepared retractable hammocks for even the most ordinary sailors. From the perspective of a time traveler, these can only be regarded as the minimum.
Wen Desi was very aware of the weaknesses of his group of people. They had courage and ambition, but lacked the will to live a hard life. Without letting everyone eat well, drink well and sleep well, allowing these people to go on voyages and adventures was tantamount to a fool's errand.
To install the sails, the shipbuilding team decided to temporarily use Chinese-style hard sails after consideration. Hard sails are quite suitable for the ability of the traversers. After all, the traversers themselves do not master the technology of making soft sails. Sewing the sails
It is a specialized technology that not only requires specialized tools, but also requires a huge space. Not to mention that no one in China knew this technology at that time. Even Macau did not necessarily have sailmakers. There were no sail cloths in the warehouse of the Planning Commission.
Inventory must rely on imports. It is still unknown whether there are so many canvases available for import in Macau.
In comparison, the manufacturing and material requirements for Chinese-style hard sails are much lower. The hard sail is a flat piece, while the soft sail jib is a complex curved surface that requires professional craftsmen to sew. The soft sail must be made of special canvas.
Because the hard sail has supporting bones, it does not require high materials. Ordinary cloth or even straw mats, reed curtains and the like can be used instead. Even if it is slightly damaged, it can still be used, and temporary repairs are also very convenient.
The first advantage of a hard sail is that it has high wind reception efficiency. The hard sail is like the wing of an airplane, which can take advantage of wind from all directions. When the wind blows towards the sail at a very small angle of attack, lift is generated on the sail surface, and the lift is perpendicular to
The direction of the wind. When the ship is hit by a side wind, the lift is roughly similar to the direction of the ship, which is very efficient. Even if it encounters an oblique headwind, the ship can follow a zigzag track and still travel.
.The so-called "wind from all directions" can be used. There is a rope on one side of the sail. The sailor can adjust the angle of the sail at any time according to the change of the wind. With the ability to quickly raise and lower the sail and crosswind, it can also take a zigzag route.
It's much more convenient to get there, but the price is slower than the soft sail.
Secondly, the raising and lowering of the hard sail is easy to operate. Since there is no complicated sail cable system, ordinary people can perform the work of furling and lowering the sail with almost no special training. The furling speed is extremely fast, and in critical situations, it is even necessary to cut the main rope.
It can be done in just a few seconds. Raising the sail is slower and more laborious - there are ribs in the sail and the weight is heavier, but it does not require any special skills. The hard sail does not need to be adjusted frequently during sailing, saving the operator's hands.
.
Although in the long run, soft sail rigging will be the development trend of sailboats. Large sailboats and clippers all use this system, but the mission of the No. 0 ship is at most to go south to the Philippines and north to the Japanese archipelago, basically traveling in coastal areas.
Turn. Chinese-style hard sails are very suitable for the environment in the coastal areas of mainland China where sea conditions are complex and wind directions change.
"Let's replace it with hard sails for the time being. Once we have the ability to make sails, we can replace them." Wen Desi actually didn't like using hard sails, but the conditions reminded him that it would be better to be more realistic - apart from the industrial problems, soft sails
Sail rigging requires much higher skills from the sailor and is not as simple and convenient as a hard sailing ship. After all, Ship Zero is a ship that needs to be put into use immediately.
"In the future, steam engines will be used, so why do we need sailboats?" Li Di said.
Wen Desi shook his head: "At least in the next 20 years, large sailing ships will still be the direction of our ocean transportation-it does not require fuel. Steam engine ships do not have an advantage in bulk cargo transportation, they are not efficient and consume coal. Long-distance navigation requires
Solve the problem of overseas coal filling stations. As for when we can produce steam turbines, it depends on how quickly we can climb the technology tree."
Sailboats actually sailed until the 1950s before they were completely eliminated from the world shipping market. Before that, sailboats were still the best means of transportation for long-distance transportation of bulk cargo by sea.
"I really want to fly our ironclad ship as soon as possible." Although Le Lin, a naval controller, does not know shipbuilding technology, she still spends time in the shipyard whenever she has free time.
"In fact, it's not that difficult. Iron-hulled ships are actually easier to build than wooden ships." Wen Desi said, "As long as there are enough materials and skilled workers can keep up with the training, building a thousand-ton iron-hulled ship is a piece of cake."
"Mr. Wen, do you think we can build another 70-ton soft-sailed ship as a training ship?"
The person who spoke was Ming Qiu from the Ministry of Maritime Power. As a naval consultant, he often came to this shipyard to see the construction progress of the Navy's first self-made warship. To be honest, after getting used to seeing modern warships, I suddenly saw the Navy's warships.
It was quite strange that it was actually a sailing ship. Especially the strange gun emplacement - Ming Qiu vaguely remembered that he had seen something similar when visiting a fort built in the late Qing Dynasty. Although the reality was somewhat out of touch with his experience.
, but the basic idea of building a navy is the same: whether it is a navy in the sail era or a navy in the electronic era, people are always the most basic and critical component. Training enough sailors is a top priority. Ming Qiu also saw the visiting South China Sea Navy
I am a sailing trainer ship and feel that this method is very training and suitable for the future needs of the navy.
"What you said makes sense. I will discuss with the executive committee to allocate materials as soon as possible to start construction of another training ship, but this requires the support of the foreign trade department." In fact, a few days ago, Ma Qianzhu had sent a team from the foreign trade company
People went to Macau to see if they could find relevant materials and craftsmen.
As he was talking, a European-style sloop with a swordfish-like long tusked raft and a long row of sails was sailing crookedly in the sea outside the shipyard. The sails were hung in pieces. Look.
It turned out that there were still a few people climbing on it, and faint shouts could be heard in the sea breeze.
"Whose ship is this?" Wen Desi was surprised.
"Li Huamei's ship, the Hangzhou." Chen Haiyang reported, "I reported to the executive committee last time, and she is now teaching everyone how to sail and rope."
"It's her. She looks very active." Wen Desi thought thoughtfully, "Didn't Mond report that she was unwilling to be a coach?"
"She refused. It's not considered a formal teaching now. It seems to be just for fun."
"This is a unique pastime." Wen Desi was full of distrust.
After Li Huamei came to Lingao, the executive committee had doubts about her intentions, so they did not decide how to treat her. So they only sent people from the foreign affairs department to entertain her with good food and drinks. She was bored at the port.
Li Huamei naturally developed a relationship with the navy officers in Bopu. With her name, beautiful appearance, sharp temper and her fast boat, except for a few retired former PLA naval officers, they still maintained considerable revolutionary vigilance towards this woman.
In addition to sex, most of the navy soon lost their due vigilance and often took her boat for a ride in the waters outside the port, pretending to be learning ship maneuvering skills. Li Huamei was also generous, not only teaching various marine
She had great experience in sailing and sometimes performed various ship-operating skills. Her reputation soared and she won a large number of fans. So much so that every time the executive committee held an enlarged meeting, someone would say good things about her. The executive committee was deeply impressed by the charm of women.
