"This is the h-800 type we designed. As the name suggests, it is an 800-ton ship. It is a pure sailing ship with three masts and Chinese-style sails."
Shi Jiantao continued his introduction:
The h800a removed a mast and became a brig, with a small boiler installed at the stern to drive the steam winch; the h800a1 canceled the boiler and installed a cannon on the front and rear decks; the h-800s
Steam engine sail hybrid...
If divided by function, it can also be divided into different subtypes such as specialized agricultural and mining bulk product ships, liquid carriers, standard cargo ships and mixed passenger and cargo ships. The modular concept is implemented in the design to make it easy to modify and repair.
.
"In addition to the most common h-800 series, there are also h-500, h-1300, h-2000..." Shi Jiantao said as he placed the full series of Harmony ship model manuals compiled by the Hong Kong shipyard on Wu De's desk.
Each ship type has beautifully drawn line drawings, renderings and technical parameters. This attracted Wu De's attention.
He carefully flipped through the atlas. If he could build a large number of transport ships like Shi Jiantao boasted, then the planning institute's biggest problem of capacity allocation would be greatly alleviated.
Wu De was a fisherman and had been in the navy for many years, so he knew a little bit about things like shipbuilding. He took a look and found that what these types of river crab wheels have in common is that they use the same basic linearity, and many of them also have the same hull cross-section.
, to facilitate standardized production, just like the A320, A319 and A321 passenger planes in this plane, they only have different lengths and slightly different engine power.
The hull of the first generation crab boat was designed based on a small wooden cargo ship built by Japan at the end of World War II. In the middle of World War II, American submarines went out to the Western Pacific to attack Japanese merchant ships. They faced the u.
To deal with the threat of boats, the merchant ships were broken into pieces and organized into convoys. On the contrary, the Japanese broke them into pieces, built tens of thousands of wooden transport ships, and scattered them on the ocean for the Americans to catch.
Although most of these wooden boats were later smashed into pieces by American Catalina patrol planes and carrier-based aircraft, judging from Lingao's industrial base, they are still practical, technological, and seaworthy.
The damage-resistant models are quite well designed, and the usage environment is all over the sea area between Southeast Asia, China and Japan, and the goods to be transported are also very different.
Of course, the Harmony Wheel created by Shi Jiantao and others is not entirely a copy of Japan's design. Considering that there are almost no qualified ports and docks in this time and space, most of the estuaries and bays used as ports have shoals and dark sand. The draft of ships should not be too deep.
At present, the ships they need are mainly for offshore transportation, and the furthest reaches are the Korean Peninsula, Siam, Vietnam, and Japan. The ship type adopts a fat, flat-bottomed, shallow-draft type - similar to the "speedboats" used extensively by the Dutch on their routes.
It's the same thing. While trying to load more cargo, try to reduce the draft to maximize the use of the natural port, so that it can be easily floated in case of stranding.
In terms of power, as "Yi Shipbuilding", Shi Jiantao knew very well that it was impossible for Hong Kong shipyards to allocate high-end goods such as marine high-horsepower steam engines and fire tube boilers. The power used by the Japanese at that time was mainly "hot ball diesel engines"
"Lingao currently can neither manufacture diesel engines nor have diesel. Therefore, Shi Jiantao's choice of power for the Harmony Wheel was sails.
Considering that in the future, the Harmony Ship will be mainly used for two operations in Zhejiang and Dengzhou, and will also do some coastal trade, so it is still possible to use Chinese-style sails, which are more efficient in offshore navigation and save manpower.
However, the "Chinese-style sails" used on the river crab wheel were designed according to the drawings provided by the "Jungkong Association", a veteran society. These designs actually come from the years of experience accumulated by British and American Chinese sail enthusiasts in the 20th century, combined with modern aerodynamics.
Structural mechanics uses canvas, winches, pulleys, pulley blocks and modern technology, and has undergone simple wind tunnel testing. The reliability, maneuverability and efficiency are higher than traditional Chinese sails.
Shi Jiantao found several professional research and design works on Chinese sails written by Europeans and Americans in Lingao. Originally, he wanted to set up a specialized sailing laboratory in Hong Kong, but was rejected by the National Library, the Ministry of Science and Technology and the Navy.
Opposition: The Sail Laboratory must be located in Lingao. According to the resolution of the Senate, any scientific research department involving technology development shall not be located outside Hainan Island.
However, the Lingao Shipyard that Zhou Ke is responsible for has no interest in building a sailing laboratory. Although Zhou Ke is not good at sailing at all, he is full of admiration for European sailing suits and scorns Junk sailing suits. Naturally, he is not willing to take the lead in building sails.
Laboratory. Shi Jiantao looked for people everywhere and found the Ministry of Science and Technology. The Ministry of Science and Technology has a central fluid laboratory in the Gaoshanling area. In their view, the Sail Laboratory is essentially a wind tunnel laboratory.
Finally, based on the test results of the fluid laboratory, Shi Jiantao selected a suitable Chinese-style sail as the sail type of Harmony Wheel.
Shi Jiantao took advantage of the opportunity to return to Lingao to sell the Harmony Wheel and perfected the design of the Harmony Wheel, the Chinese sail suit, and the control part. Shi Jiantao, who had prepared a full set of drawings and process materials, was very ambitious and had no choice but to ask the Planning Institute for final approval.
Although the Harmony Wheel implements the guiding ideology of simple structure, its specific design and construction focus on various new technologies promoted by the Travel Group in this time and space: iron keel and ribs, power-assisted manual steering wheel, and improved Chinese sail rigging
, hand winch... also used "iron-clad wood structural materials" that they only used in the construction industry in the past. That is, some structural materials with greater load-bearing capacity, which in the past required larger and harder wood, used "iron-clad wood structural materials".
After the "iron-clad wood" structure is built, it can be spliced together with multiple pieces of wood, or some inferior wood can be used. Iron sheets can provide extremely high tensile strength. This iron-clad wood material was used in the United States and Germany in the old time and space.
It is a very commonly used building material and ship material in Northern Europe and Russia. Ironwood I-beams were also widely used in the buildings of Lingao Construction Corporation. They were once criticized by the "Lingao Times" as "the dregs of the new era", until the construction company
The company's architects broke into the newspaper office, grabbed Ding Ding, and gave him a "love education" before they finally got their name corrected.
"How long does it take to build your ship?" Wu De asked after reading the brochure and technical information.
"For the h-800 standard model, if all parts are manufactured, it will take no more than 60 days from assembly to launch and put into use. In the future, it will be faster as you become more proficient, and the final assembly time will not be more than 30 days." Shi Jiantao specially returned to Lingao this time.
I went to Lingao Shipyard to observe the construction process of the 901 Project ship, which is said to be put into use in 90 days. According to his thinking, it is not a problem to complete the final assembly and launch of a standard Harmony ship in 60 days.
"So where are you going to produce these parts?" Wu De asked. He knew the production concept of Harmony Wheel: parts are manufactured in branch factories in various places, and they are only assembled in Hong Kong. It is probably an ambush to say that the construction will be completed in 60 days.
.
But in the United States in the 20th century, it was possible to do this - Americans had the largest and most complete industrial system at that time. Although Lingao in this time and space also had the largest and most complete industrial system in the world, it was simply impossible to provide such a large
production capacity.
At present, the production tasks of various factories in Lingao are already at full capacity, especially the wood processing factory, the main raw material supplier for wooden boat building. Their boat material production lines are already producing in 24-hour shifts, and it is unlikely that they will continue to operate.
To provide raw materials for Hong Kong shipyards, Shi Jiantao obviously can only rely on Hong Kong's own wood processing plants. However, this plant is very weak in terms of production capacity and technical level.
"I'm going to use local production capacity in Guangdong." Shi Jiantao finally laid out his plan.
The first phase of the Hong Kong shipyard project does not have a full set of parts and components supporting companies. Except for a wood processing plant, which is considered a major supporting component, all kinds of metal parts, cables, canvas, putty, grease, and paint must be supplied by Lingao. Shi Jiantao's calculation
Yes: Gradually expand the local parts supply ratio in Guangdong: Raw materials that are not difficult to process or do not require much processing are first purchased locally in Guangdong - for example, the putty used for filling is nothing more than lime, hemp silk, and tung oil, which can be completely purchased in Guangdong.
Outsourced manufacturing. Spare parts start from the wooden structural parts of the Harmony Wheel and are supplied to local shipbuilding workshops in Guangdong.
But this is not an easy task. Shi Jiantao visited several shipbuilding workshops near Huangpu. After seeing the rough tools and components, his heart almost sank to the bottom.
But after carefully observing their construction process, Shi Jiantao discovered that although the shipbuilders' work was very rough and there were no drawings, they built the ships strictly and according to a certain pattern. The ships built followed several standards.
Ship type.
Obviously, pattern manufacturing of ships is not an alien technology to them, but has existed for a long time. It should not be difficult for them to mass-produce the same kind of parts on a large scale. From the collection of the Foreign Intelligence Service to the compilation of
According to "Common Aboriginal Ship Types Along the Coast of Guangdong", there are seven or eight types of ships larger than 100 tons. The hull structures of the same models are almost exactly the same.
But after further in-depth observation, he was poured cold water on him: the tolerances of various ship parts manufactured by shipbuilders were frighteningly large - or rather, there was no concept of tolerances in their eyes.
Of course, given the roughness of the tools they use and the concept of dimensions without specific numbers - all in their heads - it is impossible to mass-produce parts within the allowable tolerances.
