When Dingyuan Marquis Zheng Lian left the dock on his Oriental Pearl, one good eye and the other injured eye were just staring at the cargo ship full of military supplies, which made Zhang Mingcheng, who was traveling with him, very disdainful, can the Hantang Group not comply with the requirements of the contract?

But because he asked for others, he didn't say much, so he had to meditate on himself for a long time, and he was not afraid of noise, he was wearing work earmuffs.

There are technicians who are interested in military cooperation with the Zheng family group who do not care.

In the eyes of people like Director Wu Jie, his sailboat is the most worthy of attention.

The dividends of the wooden sailboat, he personally believes that it is far from being fully eaten.

Under the continuous experiments of Director Wu Jie and Fan Xiu technicians, Anjiang Shipyard finally successfully built a whale handling ship that has never been seen in the world, and now it is being led by Captain Guo Ziren to sea trials everywhere.

At the moment, it doesn't seem like a big problem.

Director Wu Jie didn't ask Secretary Yang Youxing to name it, so he named it himself, "Humpback Whale", isn't this good?

The production process of the "Humpback Whale" fully reflects the characteristics of the Hantang Group, but it is a little regrettable that it did not catch up with the ocean-going launch training operation, but there is no hurry, as long as the number of sea trials is good, then there is a chance.

The so-called whale handling ship, its scientific name is the three-masted schooner integrated transport ship, Wu Jie also expects that it can not only directly deal with whales at sea, but also play a variety of purposes such as transportation and engineering, and can even be equipped with weapons as a long-range support ship.

The three-masted schooner, which was very popular in the age of sailing, was very suitable as a commercial vessel because of its similar capacity to a full-sail ship and the need for fewer manpower. Compared to schooners that are suitable for wind-rushing sailing, and full-sail sailing ships that are suitable for long-distance sailing in the seasonal winds, the three-masted galleon combines the best of both worlds.

Many later large iron-hulled sailing ships also adopted similar sail outfits. Since Hantang Group wanted to use it to complete the business of processing whales at sea at the same time, it had to make some changes.

It has a total length of 67 meters, a width of 15 meters, a draft of 5.4 meters, a mainmast of 60 meters high, and a load of 600 tons.

It's not too big in this plane, but it's the world's first steel-ribbed wood-hulled ship on this plane.

Director Wu Jie and technician Fan Xiu of Anjiang Shipyard finally got the most cost-effective number after repeated modeling.

Its keel and ribs are forged in sections, and then truckloads are transported to the slipway to rivet them by number.

The power engines of the Anjiang Shipyard and the Estuary Forestry Base were completely finalized as early as last year, and they did not care at all about the type of power engine that appeared.

They are all pots and camel machines with water, large, medium and small. Without him, there is a lot of waste materials. Of course, their pot camel tractors can't use waste materials, only machine-made charcoal, otherwise the power output and combustion time will be a problem.

At present, there are four main types of vehicles on the roads of the Geranza area.

"Lululu", this is a rickshaw too.

"Gotta got", this is a four-wheeled carriage also.

"Tutu Tu

"Knock knock", this will be a hot bulb internal combustion tractor in the future, and it has not yet been built.

Our Anjiang shipyard is more special, "pants", "pants", "pants", this is the camel pot tractor.

The workway riveting is mainly to invite the technicians of the Red Star Industrial Zone to help, which requires technical costs, and finally has to be settled in a unified manner.

Director Wu Jie didn't want to take care of this group of people's meals, but we have given this processing fee, so you should bring your own lunches...... But he was afraid that others would see that he was stingy, so he generously said, "Friends, there is chicken for lunch!" ”

The technicians who were helping the Anjiang Shipyard riveting ignored his generosity, nor did they hear the distress in Director Wu Jie's voice.

For a while, the red rivets on the slipway flew all over the sky, and the huge hull gradually became visible when the sound of local smashing was shocking.

The Ming boatwrights present were stunned, the Hantang Group actually used steel to make keels and ribs!

Iron nails, hooks, screws and so on, this steel keel, ribs, mast is really beyond their imagination.

The tin boat can be understood by guò enamel washbasin, and this steel keel and rib plus wood, they can't think of it.

At that time, the director of Wu Jie touched his bald head very happily, and he bragged to the Ming boatman: "Do you think that the big iron ship you saw is the biggest?" I can be as big as I want, and if you take the money, we can produce a 100-kilometer boat, but you can't? ”

Of course, the Ming boatwrights quit, and they were busy doing the woodwork.

In this way, they placed orders for the Red Star Industrial Zone, and the required components were continuously delivered from the Red Star Industrial Zone.

The hull and deck panels are also pre-machined, as long as they are installed in position and order according to the numbers on the drawings.

The cross-sections of those plates are cut into W-shaped long grooves to facilitate the joint of the plates when they are spliced together.

When the deck is installed, the section is coated with casein glue, and a large number of nails are used inside and outside the hull to make the whole hull a whole to improve strength.

The Anjiang plant put the safety of the Humpback Whale ahead of performance.

These ocean-going vessels have double hulls and unconnected cabins below the waterline, and large pieces of balsa wood are processed to fit between the inner and outer hulls and fit tightly to the planks.

Unfortunately, due to the fact that the current quantity is not enough, it can only be used in important places.

The heaviest wood in the world is ironwood, which weighs 1,122 kilograms per cubic meter; So, what is the lightest wood? It is a large tree of the ceibaceae family native to the Americas, which weighs only 115 kilograms per cubic meter, which is one-tenth of water.

A normal adult can lift a barsa wood that is about 8 times its own volume.

It is said that Columbus first discovered the New World in the 15th century. Since then, European colonists have rushed to send troops to occupy territory in the Americas.

When the Spanish army arrived in Ecuador, they were amazed to see seven indigenous girls drifting down the rough waves on a raft made of special wood in the roaring river to the island of Satsuma, sometimes on the crest of the waves, sometimes in the splash, but never sinking.

Later, the soldiers also found that this kind of wood is particularly light and has good antiseptic properties, and local craftsmen use it to make a variety of household utensils and handicrafts, which are very popular with people and are often in short supply.

Therefore, the Spanish soldiers called this wood basa wood.

Later, balsa wood was shipped to Spain and throughout Europe, where it gradually spread throughout the world.

Basha wood is not only particularly light wood, its wood is fine and white, insects do not eat, ants do not eat, and it grows rapidly, the trunk is tall and straight, the branches are few, and the leaves are large and round.

In the tropical rainforest, it is like a Dai girl wearing a tight short tube skirt, a silver belt, and a green paper umbrella, slender and beautiful, slim and slim.

Hantang Group values that it can be widely used in aviation, navigation, sound insulation, heat insulation, interior decoration, etc., and the effect is particularly good.

The Hantang Group has been successfully cultivated in the glass greenhouse breeding area of the Chiji Agricultural Zone, and in that world, Guangdong, Fujian, Yunnan and Hainan have more readers than they read pirated copies.

In fact, when their basha wood was still a seedling, the Hantang Group found in the trade that Manila had stock, but not too much.

So they bought it to be cut into small pieces to make canvas-filled life jackets, which had already been fitted to the warships in the ocean-going training program.

Hantang Group simply took down all the inventory of other people, and we just used it to make thermos stoppers, okay?

The purchase of the Hantang Group invisibly speculated the price of Basha wood, and when the Spaniards were fortunate enough to ship it from South America and wanted to get a good price, they found that the price of Basha wood had dropped a lot, and the Hantang Group itself was able to produce it...... You see, this basa wood grows so fast.

Of course, that's all for later.

In this way, the watertight compartment of the past has become a "half-timber chamber", and even if it hits the reef or encounters a strong tropical storm and the outer hull of the ship is damaged, there is not much buoyancy.

Later, this "waterline wooden dense cabin structure" became the standard design of Han and Tang warships, but the filling material was changed to a lighter flame-retardant foam material.

In fact, this three-masted schooner carrier was originally designed to be four-masted, but in order to deal with whales, a mast was subtracted in order to make longitudinal space, and now it is in the form of a three-masted schooner, and the position of the mast has been recalculated.

The Humpback Whale's steel conical hollow mast is up to 60 meters high, and in the future, merchant ships of the same class with different roles will still be able to use the four-masted schooner design.

The cable system on its foremasts uses full-bone flat-topped sails with ropes; The tail sail was replaced with a jib to strengthen the mast by adding a rear support cable.

When the sailboat is sailing downwind, the wind pressure center will move forward, so that the ship will have a tendency to turn downwind to form a downwind rudder; When a ship is sailing against the wind (not the headwind), the center of wind pressure moves back, causing the ship to have a tendency to turn upwind to the side to form an upwind rudder.

In the past, the solution to this problem was to turn the rudder downwind when the upwind rudder was upwind, turn the rudder upwind to maintain the course when the rudder was downwind, and lower the sail when the rudder could not be solved (lower the tail sail when the upwind rudder is downwind and lower the foresail when the downwind rudder is downwind), or relax the corresponding sail rope (loose sail), but these methods will affect the speed.

Director Wu Jie ingeniously installed a movable water shield for the "Humpback Whale".

It is mounted on the downwind side and moves back and forth through guò, increasing lateral drag while moving the center of lateral drag of the boat to balance the upwind or downwind rudder problem without reducing the efficiency of the sail.

Commonly known as the "waist rudder", the water plate is used to increase the lateral resistance of the boat, and is installed on the downwind side of the amidship to reduce drift when sailing against the wind. Since then, all Taiwanese schooners have had waterboards.

Due to the pursuit of loading space and loading weight, it adopts a U-shaped bottom, and the underwater linear type is designed in strict accordance with the fluid science specifications, in order to achieve the best cost performance.

In order to take into account the center of gravity when hoisting whales, it increases the ballast weight, which enhances stability and righting torque, allowing the boat to be equipped with a more powerful sail rope system and a hanger that can bear about forty tons.

The sail rigging is connected to the cockpit of the stern with a number of pulleys, and the sailor controls the sails with two pedal winches. There are two steering wheels in the cockpit, and the helmsman can use the upwind steering wheel to control the heading so that the view is not obstructed by the sails. For safety reasons, a subrudder blade has been added to this model, which can still sail if the main rudder is damaged.

A three-ton pot camel machine is also installed on the ship, which can easily lift medium-sized blue whales onto the deck of the ship in combination with a human pulley group.

Of course, it is also needed to provide a heat source when processing whale oil.
